Referring to the drawings the numeral [5 designates generally a housing structure, which has mounted therein a coin changing mechanism including a coin delivery means generally designated as it, and an electrically operable selector mechanism generally designated as H. The .delivery mechanism i6 comprises a series of outer vertically disposed tubular magazines l8, I9, 20, 2| and 22. The coins in the magazines [8 to 22 inclusive are adapted to gravitatingly move downwardly in the magazines as the lowermost coins in the magazines are discharged therefrom.

The magazines I 3, l9, and 20 are secured to the top wall 23 of a slide housing generally designated as 26, and the housing 24 has slidably mounted therein a plurality of horizontally slidable coin delivery slide members 25, 26, and 2.7. The slide member 25 is slidable beneath the magazine 18, the slide member 26 is slidable beneath the magazine i9 and the slide member 21 is slidable beneath the magazine '23. The housing 24 is provided with a bottom wall 28 having openings 29, 3t, and 3| therein which overlie a coin delivery chute 32. The coin delivery chute 32 is formed of a downwardly inclined bottom wall 33. A vertical wall 34, and upstanding side Walls 35, and the chute 152 communicates at its lower or forward end with a delivery opening 36 formed in the front wall 37 of the housing 15. The housing 2:1 has fixed to the bottom wall 28 thereof a block 38 which is disposed beneath the lower end of the magazine l9.

The space between the upper face of the block 38 and the inner face of the top wall 23 of the housing 24 is suflicient to permit a small coin such .as a dime to slide between the block 38 and the top wall 23. Theslide I9 is of a thickness sufficient to effect movement of the lowermost coin in the magazine l9, so that this coin will be moved forwardly and will then gravitatingly drop downwardly into the interior of the housing 23, and downwardly through a delivery opening 38 in the bottom wall 28 which is positioned forwardly of the block 38. The slide 21 is of substantial thickness, and in the present instance is of a thickness substantially equal to the distance between the top and bottom walls 23 and 28 respectively, so that five pennies may engage in the opening 43 which is formed in the forward end portion of the slide 21 and which is adapted to normally register with the lower open end of the magazine 26. The magazine 20 is adapted to receive pennies, and upon forward movement of the slide 21 the pennies in the recess 40 are adapted to move with the slide 21 and then drop downwardly through a delivery opening 3| formed in the bottom wall 28 forwardly of the magazine 26. The slide 25 is formed with an opening 42 registering with the lower end of the magazine I8 and the single coin engaging within the opening 42 is adapted to be discharged through an opening 43 formed in the bottom wall 28 forwardly of the magazine I8.

The magazine I8 is adapted to receive half dollars, and one coin of this denomination is moved from beneath the lower end of the magazine l8 and then discharged into the delivery opening 43 from where the coin drops into the delivery chute or hopper 32. A guide or slide housing 44 is disposed in laterally spaced relation to the housing 24, being the second one of the outer pair of delivery housings and is secured to the lower ends of the two magazines, 2| and 22. The housing 44 has slidable therein a pair of slide members 45 and 46 which are slidable beneath the lower ends of the magazines 2| and 22. The slide members 45 and 46 may be constructed integral with each other and each slide member 45 and 46 is adapted to have an opening therethrough registrable with the lower ends of the magazines 2| and 22 when the slide members are in their normal coin receiving position.

The slide members 45 and 46 are similar to the slide members 25, 26, and 21 with the exception that the slide member 46 is substantially thicker than the slide member 45, so that when the slide member 46 is moved forwardly two nickels will be moved out from beneath from the stack of nickels which are positioned in the magazine 22, for delivery through a delivery opening 6| formed in the housing 44. The magazine 2| is adapted to receive quarters and the slide 46 is adapted to move only one quarter from beneath the stack of coins positioned within the quarter magazine 2|, for delivery through a delivery opening 62 in the housing 44. The outer pair of housings 24 and 44 are associated with each other and the slide members carried thereby are movable as a unit so that when a dollar is inserted in the coin controlled slide operating mechanism, the slides in the housings 24 and 44 will deliver coins of several denominations making a total of one dollar.

The coin delivery mechanism also includes a second pair of guide housings 41 and 48 which are disposed inwardly from the housings 24 and 44. The housing .41 has secured to the upper side thereof a pair of upstanding coin magazines 4'9 and 58. The magazine 49 is adapted to receive dimes, whereas the magazine 56 is adapted to receive pennies. The housing 48 has secured to the upper side thereof a pair of upstanding magazines 5| and 52. The magazine 5| is adapted to receive nickels, whereas the magazine 52 is adapted to receive quarters. The housing 41 has slidable therein a pair of coin delivering slides 53 and 54 which may be formed integral with each other and the slide 53 is adapted to deliver one dime into a delivery opening 55 which is formed in the bottom wall of the housing 41. The housing 41 is also provided with a second delivery opening 56 forwardly of the magazine 56 through which the pennies moved forwardly by the slide 54 are adapted to drop for delivery to the person inserting the coin in the coin mechanism through the delivery chute or hopper 32. The slide 54 is adapted to move five pennies forwardly from beneath the lower end of the stack of coins disposed in the coin magazine 50. The housing 48 has slidable therein a pair of integral slide members 51 and 58 and the housing 48 is formed with a delivery opening 59 forwardly of the magazine 5| through which two nickels are adapted to drop. The housing or guide 48 is also formed with a second delivery opening 68 forwardly of the magazine 5| through which one quarter is adapted to drop when this one quarter is moved forwardly from beneath the stack of coins in the magazine 52 upon forward movement of the slide 58.

An inner slide housing or guide 63 is dispose between the housings 41 and 48 and has slidable therein slide members 64, 65, and 66. The housing 63 has secured to the upper side thereof in upstanding relation coin magazines 61, 68, and 69. The coin magazine 68 is disposed above the slide 65 and the coin magazine 69 is disposed above the slide 66. The slide 64, 65, and 66 may be formed integral with each other, and may be provided with suitable openings for registry with the lower ends of the magazines 61, 68, and 69 respectively, so that when the slides 64, 65, and 66 are moved forwardly the coins carried therewith will be discharged into a delivery opening 10 which is common to all of the slides 64, 65, and 66 and which communicates with the hopper or delivery chute 32. The slide 64 is adapted to move one dime from beneath the stack of dimes in the magazine 69; the slide 65 is adapted to move five pennies from beneath the stack of pennies in the magazine 68 and the slide 66 is adapted to move two nickels from beneath the stack of coins in the magazine 60 so that proper change for a quarter will be delivered from the magazines 61, 68, and 69 through the delivery hopper or chute 32.

An intermediate pair of slide housings or guides 1| and 12 are disposed between the housings 41 and 48 and have secured in upstanding relation thereto coin magazines 13 and 14 respectively. The housing or guide 1| has slidable therein a coin delivery slide 15 for delivering five pennies from the penny magazine 13 to a delivery opening 16 formed in the forward lower portion of the housing 1|. The housing 12 has slidable therein a coin delivering slide 11 which is slidable beneath the lower end of the magazine 14 for delivering one nickel from the nickel magazine 14 to a delivery opening 18 formed in the forward portion of the housing or guide 12. The delivery openings 16 and 18 communicate with the hopper or chute 32 for delivering the ejected coins to the person inserting one dime in the coin slot toibe hereinafter described.

A centrally disposed guide housing 18 is disposed between the two housings 1| and 12 and forwardly of the housing 53. The housing I9 has secured in upstanding relation thereto a coin magazine 80 which is adapted to receive pennies for delivery to the delivery chute or hopper 32 when a coin delivering slide 8I which is slidable in the housing 19 is moved forwardly from beneath the magazine 80. The coins which are five in number and which are moved forwardly by the slide 8| are discharged into a delivery opening 82 formed in the forward portion of the housing 79 and which communicates with the delivery hopper or chute 32.

The coin selector mechanism II includes a vertically disposed coin receiving chute generally designated as 83 which is substantially V-shaped in side elevation and is open at its upper end. The upper end of the chute or coin guide 83 is disposed beneath a hinged closure or door 84 carried by the top wall 85 of the housing I5. The closure 84 is provided with a coin slot 88 communicating with the upper or large end of the chute 83. The lower or small end of the coin receiving chute 83 is secured by means of a bracket 81 to a coin receiver 88 mounted on the bottom wall 89 of the housing I5 rearwardly of the coin delivery mechanism It. The guide 83 comprises an inner pair of side walls 90 which are of insulated construction and are secured at one edge thereof to a vertical end wall 9! which is also of insulated construction. A metallic outer housing or jacket encloses the insulated side walls 90 and includes a pair of outer side walls 92 and 03 which are connected together by an end wall 94. The end wall 94 is disposed opposite from the end wall 9i. The end walls ill and 94 are disposed in downwardly convergent relation as shown in Figure 3, the angular relation of these walls one to another being such as to effect a wedging and stopping of coins of different denominations as these coins move downwardly in the guide 83.

Th end wall 8| adjacent the upper portion thereof is provided with a coin delivery opening 95 which is of sufficient length to permit the delivery of a dollar therethrough. A contact 96 is disposed in inwardly projecting relation with respect to the opening 95, projecting inwardly a slight distance from the inner wall SI for engagement with a dollar which is dropped into the chute or guide 83. The contact 96 constitutes a means for limiting the downward movement of a dollar in the guide 83 and is carried by a U- shaped supporting member 81. The supporting member 97 includes a bight portion 98 carried by parallel arms 09 which are slidable in an opposed pair of upwardly and rearwardly inclined guide members I and I0! positioned on the opposite sides of the housing or jacket formed by the walls 92, 93, and 94.

The guide structures H30 and HH are formed with guide channels I02 and I03 respectively within which the parallel arms 95 slidably engage. The guide member 93 is also formed with an opening E04 below the opening 95 which is adapted to confront a half dollar. A contact member I05 which is carried by the bight portion I06 of a U-shaped support is adapted to project inwardly a slight distance through the opening I04 for engagement with a half dollar and for limiting the downward movement of the half dollar within the guide 83. The bight portion I08 includes a pair of parallel arms I01 which are slidable in a pair of opposed guide members I08 and I09 carried by the side walls 02 and 93.

The coin chute or guide 83 is also formed with a coin delivery opening IIO disposed below the opening I04 which is adapted to confront a quarter engaging with the guide 83. A contact member III carried by the bight II2 of a U- shaped member I I3 is adapted to project a slight distance through the opening I I0 for engagement with the edge of a quarter and limit the downward movement of the quarter within the guide 83. The U-shaped support II3 includes a pair of parallel arms or legs II4 which are slidable in outwardly opening guide members H5 and H8 carried by the side walls 92 and Q3 respectively.

The guide member 83 is formed with a delivery opening II I below the opening IIO which is adapted to confront a nickel disposed in the guide 83. A contact member II8 which is carried by the bight portion II9 of a U-shaped member I28 is adapted to project slightly into the guide 83 through the opening II 7 thereof for engagement with the edge of a nickel and to limit the downward movement of the nickel within the guide 83. The parallel arms I 2| of the U-shaped member I20 are slidable in outwardly opening guides I22 and I23 which are fixed to the side walls 92 and 83 respectively and are inclined to the horizontal.

The guides I88, I89, H5, and H8 are also inclined to the horizontal. A lowermost opening 124 is formed in the end wall 0| below the opening ill and. is adapted to confront a dime engaging within the lower portion of the guide 83. An inwardly projecting stop member I25 may be fixed to the lower end portion of the guide 83 in order to limit the downward movement of the smallest coin or dime within the guide 83. A contact member I28 which is carried by the bight 52'! of a U-shaped support I28 is adapted to project slightly into the interior of the guide 83 for engagement with the peripheral edge of a dime to form an electric contact with the dime and also to limit the downward movement of the dime within the guide 83. The U-shaped support I28 includes a pair of parallel arms or legs I28 which are slidable in opposed outwardly opening guide members 530 and I3! which are inclined to the horizontal and are fixed to the side walls 92 and 93. The U-shaped member '91 has pivotally connected to the free ends of the parallel arms 89 thereof, a pair of links I32 and. I33.

The link I32 at its forward or lower end is pivotally connected to an arm I3 which is fixed relative to the integral slides 25, 28 and 27. A guide roll I35 is rotatablycarried by the housing 2t on the inner side thereof and the arm' I34 engages the roller I 35. The arm I34 is adapted to move in a horizontal plane whereas the link or connecting member I32 moves in an upward and rearward direction.

The link I33 at its lower or forward end is pivotally connected to an arm I35 which is fixed relative to the two integral slides # 25 and 40. The

U-shaped member formed by the bight I06 and the parallel arms I0! has pivotally connected to the parallel arms I01 thereof a pair of downwardly and forwardly inclined links I3-I and I38. The link I31 at its lower or forward end is 'pivotally connected to an arm I 39 which is fixed relative to the integral slides 53 and 5G and the forward or lower end of the link I38 is 'pivotally connected to an arm M0 which is fixed relative to the integral slides 51 and 58. The parallel arms H4 of the U-shaped member I I3 are .piv-

otally connected to a pair of links I II and I42 which at their lower forward ends are connected to arms I43 and I44 respectively which are fixed relative to the integral slides 64, 65, and 66. The arms I43 and I44 are disposed on opposite sides of the housing 19 as shown in Figure l.

The U-shaped member I has-pivotally connected to the lower ends of the parallel arm I2I thereof, a pair of connecting links I45 and I46. The links I45 and I45 at their lower forward ends are disposed in convergent relation and are fixed together. The convergent ends of the links I45 and I46 are pivotally. connected to a rearwardly extending arm I41 which is fixed rela tive to the slide SI.

The U-shaped member IE8 has pivotally connected to the parallel legs I29 thereof a pair of downwardly and forwardly inclined links or connecting members I48 and I49. The lower forward end of the link I48 is pivotally connected to a rearwardly extending arm I50 fixed relative to the slide 15. The lower forward end of the link I49 is pivotally connected to the rear end of an arm I5I which is fixed relative to the slide 11.

In order to provide a means whereby the in serted coins which are dropped into the chute or guide 83 may be ejected from the chute or guide 83, I have provided a coin ejecting and circuit closing structure generally designated as I52. The coin ejecting structure I52 includes an upwardly extending contact carrier I53 which is pivotally mounted as at I54 on a bearing structure I55 fixed to the bottom wall 69. The carrier I53 has secured thereto a longitudinally arcuate contact member I56 which is movable through an opening I51 formed in the end wall 94. The inner end of the contact member I56 is disposed in a position for engagement with a dollar and is disposed opposite from the contact 66 so that when a dollar is inserted in the guide 83, this coin will bridge the two contacts 96 and I58, and thereby close an electric circuit within which these contacts are interposed.

A second longitudinally arcuate contact member I58 is fixed to the carrier I52 below the contact I56 and is movable through an opening I59 formed in the end wall 94 substantially opposite the opening I04 and confronting the contact I05. When a half dollar is inserted in the guide 83 this coin is adapted to bridge the space between the two contacts I05 and I58 so as to close the electric circuit to the electric operator for the carrier I52. The third contact I60 is fixed to the carrier I52 below the contact I58 and is movable through an opening I6I formed in the end wall 94 substantially opposite the opening I I0. When a quarter is inserted in the guide 83, this coin is adapted to wedge between the two contacts III and I 60 so as to thereby bridge the space between these contacts and close an electric circuit to the electric operator for swinging or moving the carrier I52. Another longitudinally arcuate contact I62 is fixed to the carrier I52 and is movable through an opening I63 formed in the end wall 94 substantially opposite the opening I I1. When a nickel is inserted in the guide 83, this coin is adapted to wedge between the two contacts H8 and I62 for closing the electric circuit to the operator for moving the carrier I52. A lower longitudinally arcuate contact I64 is fixed to the carrier I52 below the contact I62 and is movable through an opening I65 formed in the lower poropening I24 and when a. dime is inserted in the guide 83 this coin is adapted to wedge between the two contacts I26 and I64 for closing an electric circuit to the operator for the carrier I52.

The upper portion of th carrier I52 is swingable in a substantially sector shaped housing generally designated as I66 including a pair of side walls I61 and I68 disposed in parallel relation. The side walls I61 are formed adjacent the upper end portion thereof with a longitudinally arcuate guide I69 within which a roller I10 carried by the carrier I52 is adapted to movably engage. The side walls I81 are also formed with longitudinally arcuate guide channels I1I, I12, I13, and I14 within which rollers I15, I16, I11, and I18 are adapted to movably engage. The channels I1I, I12, I13, and I14 are correlated with contact members I58, I60, I62, and I64 respectively.

In order to provide a means whereby the carrier I52 may be rocked rearwardly to a coin ejecting position upon insertion of a coin within the guide 83, I have provided an electric motor I19 which is disposed rearwardly of the guide 83. The motor I19 has mounted on the shaft I thereof a plate I8I having an eccentrically dis.- posed pin I82 mounted therein. A U-shaped carrier operator I83 has the parallel arms I84 thereof disposed on opposite sides of the guide 83 and the housing I66.

The bight I85 of the operator I83 has a rear wardly extending arm I86 fixed thereto which is pivotally mounted at its rear end of the crank pin I82. The forward or free ends of the parallel arms I84 of the U-shaped operator I83 are pivotally connected to a pair of oppositely extending bars I81 which are fixed to the carrier I52 at a point below the upper end thereof. In Figure 10 there is disclosed diagrammatically the electric circuits associated with the motor I19 and the contacts hereinbefore described. These electric circuits include a conductor I88 connected to one side of the motor I19 and connected by means of conductors I89, I90, I9I, I92 and I93 to the contacts 96, I05, III, H8, and I26 respectively. The other side of the motor I19 is connected by means of a conductor I94 to the car.- rier I52. In this manner when a coin is inserted in the guide I83 this coin will bridge the correlated pair of contacts and effect a closing of the electric circuit to the motor I19. When the carrier I52 is moved to its rearmost position the coin engaging between the engaging contacts will drop down, and the electric circuit to the motor I19 will thereby be broken.

In order to provide for the continued operation of the motor I19 after the coin is released from between a pair of contacts, I have provided a stationary resilient contact I95 which is connected by means of a conductor I96 to the conductor I88. The contact I95 is mounted on a plate I91 mounted on the front wall I98 of the coin receiver 88 which is positioned below the rear contacts 96, I05, III, H8 and I26. A second resilient contact I99 is fixed to the rear side of the carrier I52 in a position to engage the stationary resilient contact I95after the carrier I52 has initially started its coin ejecting operation.

The two contacts I95 and I99 are shown more clearly in Figure 11 wherein it will be noted that these contacts are in disengaged position when the carrier I52 is in its normal forward position so that the electric circuit to the motor I19 within which the contacts I95 and I99 are interposed will be broken just prior to the time that the carrier I52 reaches its foremost or normal position. By means of the two contacts I95 and I99 the continued operation of the motor H9 is assured so as to provide for one complete revolution of the crank plate I8I and for the complete cycle of the operator I83 which is connected to the carrier I52. In order to provide for a return of the several coin delivery slides to their normal positions beneath the correlated coin magazines when the carrier I52 has returned to its normal forward position, which is the position shown in Figure 3, I have provided a spring 200 which is connected at one end to the slide member 25, 26, and 21 and the other end to the front wall 31 of the housing I5.

The slide members 45 and 40 are also returned to their normal position beneath the magazines 2| and 22 by means of a spring 20I fixed at its rear end to the slide 46, and its forward end to the front wall 31. The slides 53 and 54 are returned to their normal position beneath the magazines 49 and 50 by means of a spring 202 which is connected to the slide 53 and to the front wall 31. The, slide members 57 and 58 which are correlated with the slide members 53 and 54 are returned to their normal position beneath the magazines and 52 by means of a return spring 203 connected at one end to the slide 5'! and the other end to the front wall 37.

The slides 64, 65, and 66 are returned to their normal positions beneath the magazines 61, 68, and 69 respectively by means of return springs 204 and 205. The slides I5 and II are returned to their normal positions beneath the magazines I3 and I4 by means of return springs 206 and 207. The slide 8| is also returned to its normal position beneath the magazine 80 by means of a return spring 203. By means of the slide return springs hereinbefore described, the contacts 96, I05, III, H8, and I25 are placed under tension during their rearward and upward movement and also promptly returned to their normal positions with respect to the guide 82 so that when the carrier I52 is in its normal forward position the contacts 93, I05, III, H8 and I26 are also put in their normal positions.

The coin receiver 88 which is adapted to receive the inserted coins which are to be changed, comprises a receptacle formed of side walls 209, 2I0, a rear wall 2I I, bottom wall 2I2a and front wall I98. A top wall 2I2 is fixed within the receptacle 88 below the upper end thereof and is formed with an opening 2I3. The opening 2I3 is closed by means of a pair of doors 2M and 2I5 which are hingedly secured to the top wall 2 I2 by means of hinge members 2 I 6, and 2 I I respectively. The doors 2 I4 and 2 I 5 are adapted to gravitating- 1y swing downwardly into an open position 'so as to permit a coin engaging on the upper face thereof to drop into the receiver 80. The doors 2I4 and 2 [5 are resiliently and normally held in a closed position by means of a pair of pivoted a downwardly bent door engaging cam 2.26 which is adapted to engage the underside of the door 2I4, when this latter door is in an open position, and the arm or lever 2I8 is moving inwardly to effect closing or raising of the door 2 I4.

The arm or lever 2I9 is provided with a door closing cam 22'! on its inner edge thereof and adjacent the forward portion for engagement with the under side of the door 2I5 so as to facilitate the raising of the door 2I5 when the door 2I5 is in an open position. The forward end of the arm or lever 2I8 is provided with an integral and obtusely disposed extension 220, and a pivoted arm operating member 229 is pivotally mounted as at 230 on the extension 223, and extends obtusely with respect to the arm or lever 2| 8.

A spring 23I carried by the extension 228 bears against the outer edge of the arm or lever operator 229 so as to normally maintain the extension or operator 229 in alignment with the extension 223. The arm or lever 259 is formed at its forward end with an obtusely disposed integral extension 232, and a lever or arm operator 233 is pivotally mounted as at 234 on the extension 232 and is constantly urged to an aligning position with respect to the extension 232 by means of a spring 235. Ihe two pivoted operators or lever extensions 229 and 233 are disposed in forwardly convergent relation and are provided at their forward ends with enlarged heads 23B and 23'! respectively. A V-shaped lever operator 238' is carried by a rearwardly extending support 239 which is fixed to the rear side of the carrier I52 and is disposed in a position for engagement with the head members 236 and 231, so that upon rearward swinging movement of the carrier I52 the levers 2 I0 and 2 I 9 will be swung outwardly to a door releasing position. The supporting memher 239 has fixed thereto a pair of laterally extending pins 240 which are adapted to engage and rest upon a supporting track 24I disposed forwardly of the receptacle 33.

The track 24I is supported in forwardly spaced relation with respect to the receptacle 88' by means of upwardly and forwardly extending supporting braces 242 and 243. The upper end of the guide 83 is fixed to the lower wall 244 of a depending housing 245 which is disposed below the under side of the closure 84. The bottom wall levers or arms 2 I8 and 2 I9 respectively which are pivotally mounted at their rear ends on pivot members 220 and 22I respectively.

The pivot members 220 and 2 2I engage through the top wall 2I2. A spring 222 mounted on a pin 223 carried by the top wall 2 I2 bears against the forward end and outer edge of the door clos- 244 is provided with a slot or opening 245 registering with the open upper end of the guide 283. A pair of resilient flaps 241 are positioned within the housing 245 and are normally disposed in a horizontal position with their adjacent edges in substantial contact so as to thereby close the coin slot 85. In order to provide a means whereby a second coin cannot be inserted in the guide 83 while the carrier I52 is moving either rearwardly or forwardly, I have provided a guide closing or locking plate 243 which is fixed at one end to the inner side of the carrier I52 and is slidab-le through an opening 249 formed in the end wall 94. The guide closing or looking member 248 is of resilient construction, being normally longitudinally bowed, and is adapted to slide over the surface of the bottom wall 244 of the housing 245 for closing the opening of the slot 243.

In the use and operation of this coin changing device the various coin magazines may be filled with coins by raising the closure 84 which is nor mally locked by means of a locking structure 250. When the magazines have been filled, the coins positioned therein will engage the respective slide or coin delivery members positioned therebeneath. In the event it is desired to change a dollar this coin is inserted in the coin slot 86 and moved downwardly until the coin engages and wedges between the two contacts 96 and I56. The dollar will engage the contact I56 adjacent the lower portion thereof and will engage the contact I56 adjacent the upper portion thereof. As soon as the dollar engages between the two contacts 96 and I56 this inserted coin will close the electric circuit embodying the conductors I89, I88, and I94 to the electric motor I19. The motor I19 will thereupon swing the carrier I52 rearwardly and as the carrier I52 swings rearwardly the coin will roll with respect to the two contacts 96 and I56, rolling beneath the contact 96 after the coin passes through the opening 9|. The rearward movement of the carrier I52 will pull the yoke or U-shaped member 91 rearwardly and upwardly, which will effect rearward movement of the links I32 and I33. Rearward and upward movement of the links I32 and I33 will pull the slides 252621 and the slides 45 and 46 respectively rearwardly to a coin delivering position.

Rearward movement of the slides 25, 26, and 21 will effect delivery of the coins to the delivery chute or hopper 32 and rearward movement of theslides 45 and 46 will effect delivery of the coins to the delivery chute or hopper 32. As the slides 25-2 6--21 are moved rear-wardly the spring 208 will be tensioned so that immediately upon dropping of the dollar from between the two contacts 96 and I 56 the spring 288 will return the integral slides 25-26--21 to their normal forward position beneath the magazines I8 I9 and 20. The same operation is effected by means of the spring 20I with respect to the slide 45 and 46. After the dollar or other coin has been delivered down onto the closed doors 2 I4 and 2I5 of the receiver 88, the motor I 19 will continue in operation by reason of the closing of the circuit thereto which is effected by the contacts I95 and I99. The contact I99 is connected by a conductor 25I to the conductor I94 so that when the contacts I95 and I99 are in engagement with each other a circuit will be closed from the con tact I95 through the conductor I96 and conductor I88 to one side of the motor I19. The other side of the motor I19 is interposed in the closed circuit by means of conductors I94 and 25I, the latter being connected to the contact I99.

When the carrier I52 initially moves rearwardly to an inserted coin ejecting position and a change delivering position, the lever opening or swinging wedge 238 will swing the levers 2 I8 and 2 I9 outwardly to a doorreleasing position thereby permitting the doors 2M and 2I5 to gravitatingly swing downwardly to an open position. This swingingmovement is provided prior to the dropping of the co n which closes the circuit to the motor I19. When the wedge member 238 passes the heads or forward ends 236 and231 of the pivot members 229 and 233, the levers 2I8 and 2 I9 will be promptly returned to a door closing position by the springs 222 and 224. At the time the inserted coin drops down from between the two contacts 96 and I56, as an example the door 2I4 and 2I5 will be in a closed position in view of the fact that at this time the wedge shaped lever operator 238 will be positioned inwardly of the pivoted arms 229 and 233; the inserted coin which is at this time effecting operation of the change delivering slides will drop onto the closed doors 2I4 and 2I5 and will stay.

plungers, means connecting the other side of said "352- plungers means connecting each plunger with a on the upper sides of these doors until a subsequent coin is inserted in the guide 83.

By this means the owner of the change mechanism will be able to determine the value'of the inserted coin, so that if any coin magazine should be empty and an insufficient number of coins be delivered to the delivery chute 32, the owner of the device may promptly make up the deficiency and may also resupply the empty coin magazine. The disposition of the last coin changed on the closed doors 2I4 and 2I5 also provides a means whereby the person desiring the change and receiving the same, cannot dispute the amount of change received.

When the wedge shaped member 238 returns to its forward position upon forward swinging of the carrier I52, the levers 2 I8 and 2I9 will remain in their door locking position by reason of the swinging or pivoting of the lever extensions 229 and 230 without movement of the levers 2I8 and 2 I9. This is accomplished by providing the springs 23I and 235 of substantially lighter tension that the springs 222 and 224. In this manner the levers 2I8 and 2I9 are only swung outwardly to a door released position when the wedge shaped operator 238 is moved inwardly.

After the carrier I52 on its return stroke moves forward to a point where the two contacts I and I 99 are in disengaged position, so as to break the electric circuit to the motor I19, the carrier I52 continues forwardly to the end of its movement by means of an adjustable weight 252, which is adjustably mounted by means of a set screw 253 on an elongated support 254. The support 254 is disposed at an acute angle to the length of the carrier I52 and extends forwardly therefrom so as to gravitatingly swing the carrier I52 to its foremost or inoperative position.
