COIN-CONTROLLED MECHANISM FOR VENDING-MACHINES.

SPECIFIGATION forming part of Letters Patent No. 703,207, dated June 24, 1902.

Application filed January 20,1902. Serial No. 90.503. (No model.)

To aZZ whom, it may concern.-

Be it known that I, DALLAS KNowLToN, a citizen of the United States, residing at Washington, District of Columbia, have invented new and useful Improvements in Coin-Controlling Mechanisms for Vending-Machines, of which the following is a specification.

This invention relates to improvements in coin-controlled mechanisms for vending-machines.

The main objects of the invent-ion are to provide a simple, efficient, and positive coincontrolled mechanism, the same being adapted to permit of one or a plurality of successive operations of the delivery devices, whereby for the single coin introduced into the machine agiven number of articles may be vended or delivered before the delivery devices are again locked.

I have illustrated the invention in connection with a vending apparatus forming the subject-matter of a contemporaneously-pending application-to wit, Serial No. 61,09 9, filed May 20, 190l-which is primarily intended for the vending of cigars; but it is to be understood that the present invention is not to be limited to the application shown, but may be used in connection with other vending-machines that deliver by the operation of a slide or its equivalent.

Other objects and advantages of the invention will hereinafter appear, and the novel features of the same will be particularly pointed out and claimed;

Referring to the drawings, Figure l is aperspective view of the front portion of a vending-machine employing my coin-controlled mechanism. Fig. 2 is a longitudinal central section of the same. Fig. 3 is a plan view of the machine with the cover-plate removed, showing the coin-controlled mechanism as the same appears when the machine is locked. Fig. at is a similar View showing the parts in the position they assume after the introduction of a coin and an upward movement of the free end of the operating-lever. Figs. 5, (S, and 7 are details of parts hereinafter referred to.

Similar numerals of reference indicate similar parts in all the figures of the drawings.

The machine when viewed in plan is of a general oblong shape and comprises opposite side walls 1, preferablyinclined toward their rear edges, as shown, and from about their middles being slightly and abruptly elevated, as indicated at 4, thereby forming the side walls of a superimposed hopper 6. As will hereinafter appear, the hopper 6 contains the articles to be vended. The frame of the machine also comprises the front wall 2 and the rear wall 3. A platform 5, supported by the side walls 1 and front wall 2, supports the coinway and coincontrolled and tripping mechanisms hereinafter described.

Located in the hopper 6 is an inclined feedbottom 6, which extends possibly a little over one-half the distance from the rear wall 3 toward a transverse front wall 7, that connects the two side walls of the hopper The feed-bottom, as before stated, is inclined, and terminating, as it does, short of the wall 7, GOD]- bines with the latter to produce a feed-opening 8, the adjacent edge of the feed-opening being beveled on its under side, as shown. The front end of this feed-openiug is formed by what may be termed a fixed cut-01f 9, the lower edge of which is substantially in line with the beveled edge of the feed-bottom, and said cut-off may be vertical and straight in cross-section orinclined and curvedslightly, the latter being preferable for reasons hereinafter apparent.

Below the'bottom of the feed-opening of the hopper l) and the platform 5 and in close proximity to the former and in opposite parallel inclined ways 10, affixed to the side walls 1, is asliding cut-0E 11, the same being provided with a transverse delivery slot or slots 12, the upper edges of which may be slightly rounded. lhedelivery-slotmaybe,butpreferably is not, made adjustable in width; but in the latter event, as herein, is of a width suffioient to cause it to readily receive the largest size (in diameter) of merchantable articles the machine will be called upon to vendas, for instance, a cigar. Also the length of the slot is such as will adapt it to readily accommodate the longest of such articles. It being intended when the machine is employed to vend cigars, for which it is primarily designed, to adapt said machineto vend successfully the largest, the smallest, or any intermediate size or length of cigar ordinarily made and sold it would be natural to suppose that the width of this slot or the cut-off must be necessarily made adjustable; but practical demonstration proves that the cigars will vary so slightly in diameter that a slot sufficiently wide to receive the largest cigar will successfully receive and manipulate the smallest.

Afalse, preferably L-shaped, side wall 13 is applied to one wall of the hopper 6, in this instance the said false wall being provided with any suitable well-known means of adjustment. It is preferred to slot the upper horizontal portion of the wall, as indicated at 14, and the same overlying the upper edge of the hopper-wall may be held in any of its laterally-adjusted positions by set-sore ws 15. The lower edge of the false wall and its front end are so shaped as to escape both the bottom of the hopper and the stationary cut-off 9, and thus, as will be apparent, a manipulation of the adjusting means will result in either an increase or decrease of the width of the hopper as a whole, and consequently the feed-opening. In this manner it will be seen that cigars or other articles to be vended can be readily accommodated as to length.

A suitable display-case 16 may have its front wall hinged, as at 17, to the front wall of the hopper and its rear walladapted to be secured by'a lock, whereby only authorized persons may have access. If the machine is employed for the vending of cigars, for which it is primarily intended, the cigars may be loosely dumped into the hopper and the display-case closed and locked. To better display the cigars, however, it is preferable to remove the bottom of the cigar-box 18, and place said box over the hopper, the contents of the box readily falling into the hopper and fed toward the feed-opening 8 thereof. For the purpose of retaining the box immorably in position, suitable clamps-for example, as 19--may be employed upon the upper edge of the hopper-wall.

Hinged, as at 20, to a cross-bar 21 or other support is a gage-plate 22, the same being located immediately under and in close proximit-y to the sliding cut-off 11. This gageplate preferably terminates at the front edge of the openingS of the hopper, and therefore immediately in rear of the delivery-opening 12 of the sliding cut-off and above an inclined delivery-chute 23, the delivery end of which convenient cross-bar, may have its upper free end bearing against the under side of the cut-off for the purpose of giving the same a tendency toward returning to its locked position. It will of course be understood that the cut-off is capable of being operated by any coin-controlled mechanism; but the one which I will now proceed to describe is the preferred form, for the reason that it may be regulated to vend a plurality of articles with the introduction of but a single coin. I may also provide some retarding device for the cut-off for the purpose of preventing the latter being moved too suddenly to receive and discharge a cigar. One very simple form of such retarding device I have herein illustrated. The same consists of an air-cylinder 27, suitably supported within the casing, and a piston 28, the front end of which is connected by an arm 29 with the sliding cut-off 11. The cylinder, it will'be observed, acts as an air-cushion in a manner well understood.

30 designates a coinway mounted on the platform 5 and against the front wall 2 of the casing, by the upper edge of which latter it is surrounded. This coinway is provided along its opposite edges with vertical flanges 31 and may be provided between its ends with an opening 32 of less width than the distance between the said flanges. The coinway extends from one side of-the machine to a point near the opposite side, but terminates short of the latter, at which point the platform 5 is provided with a discharge-opening 33, immediately below which and the opening 32 is located a coin-receiving drawer 3%, provided with a suitable lock. Mounted upon the sides of the casing, and therefore above and combining with the platform 5 to form an intermediate space, is a protecting-plate 35, the same having at a point above the coinway a circular hole 37, the diameter of which agrees with the width of the coinway. This protecting-plate is further provided with a longitudinally-disposed slot 36 and for the purpose of giving sight to the contents ofthe coinway may be provided with a glass-covered opening 38.

To the right of the slot 36 of the coinway,

which I might also state is continued in the platform 5 and countersunk within said platform, is a disk 39, mounted for free rotation on an axis 40. For a purpose hereinafter apparent the present disk is provided at diametrically opposite sides with two corresponding notches 41, formed in the periphery there of, and within its edge with a series of six indentations or openings 42, one edge of each of which is beveled. A segmental arm 43 overlies the disk 39 and has its outer end pivoted, as at 44, to the side wall of the casing, its free or opposite end extending to the opposite side of the said disk. On its under side a detent 45 is located, and the same is designed to successively engage with the openings 12 of the disk. A light spring 46, afflxed to a convenient point of the casing, has its free endbearing on the rear or curved side of the segmental arm.

A trip-lever 47 is fulcrumed in a plate 48, let into the platform 5, the forward end of said lever passing through a convenient opening formed in one of the flanges 31 of the coin way, and therefore terminating slightly beyond said flange in said coinway. If the opening 32 is employed in the way, the trip-lever terminates immediately above the same.

The tripping end of this lever is preferably beveled, so that a coin of the proper denomination and which would accurately fit between the flanges 31 may ride over and depress said lever, and smaller denominations of coin will of course drop through the opening 32 and be of no effect so far as operating the machine is concerned. Of course if the machine is intended to operate with a dime there will be no necessity of the opening 32 in the coinway, as the dime represents the smallest coin of our currency. The opposite or rear end of the lever 47 terminates in a depending tooth 49, and said end being the heaviest is normally lowered, so that the aforesaid tooth is in engagement with a notch 50, formed in the upper side of the sliding cut-off 11, whereby until said trip-lever is tripped by a coin the cut-off cannot be moved to the rear to effect a delivery. In rear of its fulcrum-point, but intermediate its ends, the trip-lever is provided with an L-shaped shoulder 51, which when the said lever is in its normal position that is, with its rear end depressedengages with either one of the notches 41 of the disk, whereby, as will be obvious, the disk is held against rotation. It will be clear, however, that by depressing the front end of the triplever, as by a coin in the coinway, the lever will be elevated at its front end and the L- shaped catch be brought to a position that will permit the disk to rotate.

52 designates a lever mounted to vibrate upon a pin 53. The forward end of the lever may carry a follower-plate or, as shown, be formed with a bifurcation extending under the coinway and at an angle to a longitudinal slot 54, formed in said way. Mounted in the way in the latter instance, which is the one herein shown and preferred, is a loose reciprocating follower-plate 55, the same having a pin 56 depending from its under side through the slot 54 of the coinway and engaging with the bifurcation of the lever 52. Pivotally connected to the opposite or rear end of the lever 52, as at 57, is a link 58, the opposite end of which is loosely connected to a knob 59, the stem of which depends through the slots 36 in the protecting-plates and platform and is connected with the sliding outoff 11. In the path of the link 58 lies the front or free end of the segmental arm 43, and at the point where the two come in contact when the link is moved forward the latter is provided with a flanged recess 60, adapted to receive and take over the said free end of the segmental arm. For the support of the free end of the segmental arm above the surface of the disk there may be employed a track 61, the edge of which is formed on the arc of a circle concentric with the pivot of the arm and may be provided with a shoulder 62, and thus form a stop to limit the for ward movement of the arm, a pin 63 being formed on the under side of the arm for abutting against the said shoulder.

The operation of the machine may be briefly described as follows: A coin of theproper denomination being placed in the coin-opening 37, the operating-knob 59 is pushed to the rear. The length of the slot permits the knob to have a limited movement notwithstanding the engagement of the same by the rear end of the trip-lever 47. This preliminary movement of the operating-knob moves the coin along the coinway until it has depressed the front end of the trip-lever, the rear end of which is thus disengaged from the slot 50 of the sliding cut-oft, whereby the latter is released. The manner of advancing the coin along the way will be obvious, in that the link 58, moving in a fixed line at one end, through the guidance of the slots 36 will serve to vibrate the lever 52, thus forcing the follower along the coinway. The

cut-off being thus forced to the rear, an article-in this instance a cigar-will fall into the opening 12 thereof, so that a subsequent return movement of the cut-off will cause such article to drop into the inclined discharge-chute 23 and be delivered at the side of the machine through the opening 24 or at any point to which said chute may lead. In this manner it will be obvious that the machine is adapted for single delivery. It will of course be understood that when the machine is thus used-that is, as a single-deliv ery machine-the segmental arm 43, its spring 46, and the disk 39 are omitted or removed. When, however, these parts thus enumerated are in position, it will be seen that the rearward movement of the link 58 will cause the same to contact with the free end of the segmental arm 43, so that the latter is carried to the rear. Rotation of the disk is permitted, it will be understood, by the elevating of the rear end of the trip-lever 47, the catch 51 thereof being raised so as to disengage from the peripheral opening or notch 41. The movement of the link 58 is sufficient to cause the segmental lever, through its catch 45, to advance or rotate the disk the distance of .one hole 42. As the knob is returned and the cigar or other article delivered the segmental lever through its spring 46 is likewise returned to the position shown in Fig. 3, where its catch 45 is engaged with the next succeeding opening 42.

The peripheral notch 41 havingpassed be yond the catch 51 of the trip-lever the latter will not reengage this time with the former, and therefore the catch at the rear end of the lever cannot engage with the sliding cut-off; but the trip-lever will be supported by the disk in an elevated position. The knob can now be moved to the rear, a second article, such as a cigar, caught by the slidingcut-oif and delivered, the disk being again rotated the distance between its openings 42. Still the parts will remain in the unlocked position, and a third movement of the knob and a third delivery may take place. Upon the return of the knob to its initial position for the third time (by which time three articles will have been delivered for the single coin inserted) the opposite peripheral notch 41 will have arrived opposite or in line with the catch 51 of the trip-lever, whereupon the lever will drop at its rear end, thereby throwing the catch 49 into engagement with the slot or recess 50 of the cut-off and the catch 51 into engagement with the notch 41 of the disk. In this manner after the delivery of the three articles for the one coin the parts immediately become locked and can only be unlocked and the machine again operated successively for the delivery of three additional articles by the insertion of another coin. In this manner it will be observed that, for instance, three cigars for a quarter, three for a half, or three for a dollar may be vended, as well as three for a dime or a nickel. It will be obvious that this system may be carried out so as to deliver any given number of articles for a single coin. For instance, as I have illustrated in Fig. 7, by employing but one peripheral notch and the six openings 42 the machine may be operated six times before looking. It will also be obvious that the single notch 41 may be used in connection with a disk only having three openings, and thus only three deliveries made before the parts again become locked, or, again, by employing only two openings 42 but two deliveries may take place, and so on, all of which is within the scope of my invention.
