Be it known that we, FRANK C. HINCKLEY and JOHN J. ScuLLY, citizens of thevlUnited States of America, and residents of Bridgeport, Connecticut, have invented a new and useful Improvement in Automatic Stops, which invention is fully set forth in the following specification. a

This invention relates to stop mechanism, and particularly to stop mechanism-espa cially designed for use in talking machines.

In machines of the latter type, a soundboX operatively connectedto a sound-conveying member, which together, will here ferred to as a traveling element,, has move ment relatively to arotary record-support, which support, or any other suitable motor driven member, will be referred tohereafter as a rotating element, the sound-box and sound-conveying member Igenerally being fed across therecord-support by the coaction of the former with thegroove in the sound-record tablet. It is an object of this invention to provide a stop mechanism of improved construction, whichshall stop the rotation of the record-support or other rotating element upon the completion of the traverse of the sound-box and sound-com veyin member. i

A further object of this invention is to provide stop mechanism of the character referred to, with improved means whereby a predetermined number of revolutions of the rotating element must occur before said stop mechanism can come into; :action, whether the traveling element be stationary or not. I a i i A still further object of the invention is to provide a stop mechanism of the type characterized with a manually-operable controlling member by which the machine may be stopped at any time independently of the mechanism for automatically stopping the same. a c

Yet another object of the'invention isito provide a stop mechanism of the type characterized for use in connection with a motor hinged to its support, whereby the motor may be swung into and out ofits normal position without the necessity offmanually connecting and disconnecting thetparts of the stop mechanism respectively connected to the movable motor and the stationary support.

. Other objects relate to the provision of a stop mechanism of 5 the type in question which is simple in construction inexpensive tomanufacture and install and efiicient in operation. H Stated broadly, the invention comprises, in combination, a rotating element, a traveling element, stop mechanism, a member for actuating the same shown as, a rotating member, means operatively connected withthe rotating element for movingsaid member into stop-actuating position, and means operatively connected with the traveling element for preventing the movement of said member into stop-actuating position while the traveling element continues its traverse, said stop mechanism being controlled by a member, shown as a detent, and preferably both pivotally and bodily movable, which coacts with said stop mechanism to move said controlling member out of operative relation with said actuating member upon actuation of said stop mechanism. Preferably a predetermined number of revolutions of the rotating element must occur before said actuating member comes into approximate stop-actuating position, said means operatively connected with the traveling element thereafter, and so long as the traveling element continues its traverse, preventing said actuating member from moving into final stop-actuating position. Said stop mechanism, which may be either abrake or a switch, is operatively connected with a main ual controlling member for moving said stop mechanism into starting position, and a manually-operable member is also preferably provided for effecting the actuation of said stop mechanism independently of the automatic mechanism above referred to.

The invention is capable of receiving a variety of mechanical expressions, one of which is shown on the accompanying drawings, but it is tobe expressly understood that the drawings are'for purposes of illustration and are not to be construed as a definition of the limits of the invention, reference being had to the appended claims for that purpose. I i

In said drawings Fig. 1 is an end view of a talking machine provided with automatic stop mechanism in accordance with the present invention;

Fig. 2 is a, plan view of the stop mechanism, showing the machine stopped but, for convenience, the stop-actuating member in the position it assumes during the normal operation of the machine;

Fig. 3 is a fragmentary plan, parts being omitted for the sake of clearness, showing the machine in operation and the stop-actuating member in an intermediate position;

Fig. 4 is a detail perspective of the brake lever and its controlling member;

Fig. 5 is a fragmentarydetail perspective of the motor-drive of the actuating member; and

Fig-(Sis a'perspec'tive view of the manually-operable stop-actuating member.

Referring in detail to said drawings, wherein the same reference characters designate corresponding parts in the several. figures, 1 represents the driving spindle of a rotary record-support 2 designed to carry the usual record-tablet, and 3 the usual sound-box connected to the tone-arm 4 suitably mounted on the talking machine casing as by a bracket 5, said tone-arm being mounted in any suitable way to enable the sound-box to traverse a record on said support.

Frictionally connected to the tone-arm in any suitable way is an arm 6 provided at its outer end with an operating nose 7 engaging in the slot provided by the bifurcated end 8 of a lever 9pivota'lly mounted at 10 on the motor-board 11. The opposite end of said lever 9 is provided with an operating nose 12for a purpose to be explained hereinafter. To'limit the movement of said lever, a pair of adjustable stops 13 may be threaded into lugs 14 carried by the motorframe 15.-

Rotatably mounted on the motor-frame at 16 is an actuating member 17 shown as a gear provided with a'plurality of radial teeth 18. Carried by said member 17 is a pair of lugs 18- and 19, one or both of which are designed to coact with the operating nose 12 of the lever 9 and with a controlling member to be described. Suitable means are provided for positively and intermittently rotating the member 17 from the motor of the machine. In the form shown, a pinion 20, meshing with a gear 21 in the drive of the spindle 1, is carried by a stub shaft 22 upon which is mounted a rotary pawl shown as provided with a single tooth designed to engage the teeth 18 of the member 17 and rotate the latter through a distance equal to the pitch of the teeth.

Pivotally mounted on the motor-frame at 24 is a brake lever 25 provided with an operating arm 26 and, in-the form shown, with a depending arm 27 carrying a brake element 28 designedto engage the usual brake disk of the talking machine governor. It is toibe expressly understood, however, that the invention is not limited to the use of a brake pad, as a switch might be operated by said lever 25, nor to the application of the brake pad to the governor disk, as by suitable variation said brake pad might engage other rotary members driven from the motor. The inner end of lever 25 is provided with a nose 29 for coaction with a controlling member to be presently described, said lever being normally drawn into operative relation with said controlling member by a spring 30 connected at one end to lever 25 and at its opposite end to a pin 31 suitably provided on the motorframe.

Pivotally mounted on a pin 32 carried by the motor-frame is a controlling member 33 which, in the embodiment of the invention illustrated, performs the function of a detent for the brake lever 25. Said detent 33 is also mounted on the pin 32 for vertical bodily movement longitudinally of said pin. Detent member 33, which may be desirably made by bending the same up from a form struck out of sheet-metal, is provided with an operating nose 34 designed to coact with one or both of the lugs 18 and 19 projecting upwardly from the member 17, with an car 35 designed to coact with the brake lever 25 and maintain the same in inoperative position, and with a cam surface 36 shown as an arm bent upwardly, then inclined downwardly and forwardly, and then inclined again upwardly to a point slightly in advance of the ear 35. A spring 37 suitably connected at one end to the detent member 33 and atits opposite end to a pin 38 carried by the motor-frame, normally retains said member in its lowermost position and in engagement with an adjustable stop 39 threaded into a lug 40 provided on the motor-frame, said spring, however, permitting both pivotal and vertical bodily movement of said member.

For starting the machine, a starting lever 41 is pivotally mounted on the motor-board 11 at 42 and provided with an operating nose 43 designed to engage the arm 26 of the brake lever 25. A spring 44, suitably connected to the starting lever 41 at one end and to a pin 45 at its opposite end, normally maintains said starting lever at the end of its limiting slot in the position shown in Fig.2;

Means are also preferably provided to enable the manual actuation of the stop mechver 46 is shown pivoted to the motor-board at 47, said lever being provided at one end with a finger-piece 48'projecting through a slotin the motor-board and at its opposite end with an operating nose 49 designed to engage and rotate the detent member 33.

reac es In the form of the invention shown, the motor. is mounted for movement into and out of its normal position about a hinge as shown in Fig. 2. Owing to the relation of the end 7 of arm 6 and the bifurcated end 8 of lever 9, said lever may move with the motor into and out of operative engagement with said arm without requiring manual connection or disconnection of the parts constituting the train of mechanism between the tone-arm and the stop-actuating member 17.

To start the machine, lever i1 is swung from the position shown in Fig. 2 to the position shown in Fig. 3 against the tension of spring 4st. During this movement, operating nose 4E3 engages arm 26 of lever 25 and moves said lever against the tension of spring 30 until nose 29 on said lever is moved out to a position wherein spring 3'? may snap ear 35 on member 38 behind said nose 29 to retain the stop lever in off position, as shown in Fig. 3. As nose 29 is moved outwardly, the detent member is also drawn downwardly by the spring 37 as fast as is permitted by the coaction oi the inclined end of arm 36 with said nose 29.

Brake element 28 being new withdrawn from engagement with the governor disk, the motor starts and rotates the spindle l and record-support 2. Gear 21 rotates gear 20 and, through shaft 22, the rotary pawl 23. At each rotation, said pawl engages one of the teeth of the stop-actuating member 17 and advances the same through distance equal to the pitch of the teeth. In order to advance the lugs 18 and 19 on said member [7 from their position when the machine is stepped into ope 'ative relationship with nose 12 of lever 9 and nose 34: of detent the member 1'7 must make half a revolution. While said member is making this one-halt revolution, ample time is provided for the positioning oi" the sound-box in operative relation in the outer-groove of the record tablet. Thus, assuming that there are twenty teeth on the member 17 and that gear 20 makes one revolutioi'i :tor each seven and a halt revolutions of the turntable spindle, it will require seventy-five revolutions of the turn-table before the lugs on member 17 are advanced into operative relationship with lever 9 and detent It is to be expressly understood, however, that the invention is not restricted to the use of twenty teeth on the member 1'7 nor to the lapse of one-halt a. revolution of said member before it assumes operating relationship with the lever 9 and detent 33, as any suitable numberot teeth may be employed on said member and, by suitable variation the lapse of time be- .t'ore said member assumes operative relationship with the lever and detent may be less than one-half a revolution or as much as a whole revolution.

The sound-box having been operatively engaged with the sound-record tabiet during the period when member 17 is making ahalt revolution, the sound-box and tone-arm now traverse the record and, through the triotional connection betweenthe tone-armiand the arm 6, tend to drive said arm in a clockwise direction. Operating nose 7 on said arm 6 by engagement with the bifurcated end 8 of lever 9 tends to drive said lever in anti-clockwise direction. The extent oi movement of said arm and lever is, however, limited by the engagement of said lever with one of the stops 1.3. Thereafter, until member 17 has been advanced in clockwise direction through one-halt a revolution to approximately stop-actuating position, the arm 6 will slip with respect to the tone-arm a. When one of said lugs 18 or 19 is advanced into approximately stop-actuating position, it engages the operating nose 12 0t lever 9 nd moves said lever in a clockwise direction, id lever moving arm 6 in an anti-clockwise direction, which movement is permitted by the frictional connection between said arm and the tone arm. After pawl 23 moves out of engagement with said member 17, and while it is making its rotation to the next tooth of said member, arm 6 driven by the tone-arm moves lever 9 in an anti-clockwise direction and, through its engagement with the lug on member 17, rotates the latter in a clockwise direction adistance equal to the pitch otthe teeth. Pawl23 then coming into engagement with the tooth on said member moves the latter in an anti-clockwise direetion an equal distance. Thereafter, and so long as the traveling element continues its traverse, member 17 is subjected to the intermittently and oppositely acting impulses of the lever 9 and the pawl 23, whereby it oscillates in opposite directions through alimited are. Throughout this period the other of the two lugs 18 and 19 on the member 17 is in approlrimately stop-actuating position just out of engage ment with nose 3& of detent 33. When the tone-arm ceases its traverse, lever 9 is no longer moved in an anti-clockwise direction to move member 17 in a clockwise direction. Said member therefore remains in the position to which it has been moved by the pawl 23, whereupon at the next engagement of pawl with member 17, said member is in an anti-clockwise direction advanced through a further distance to engage the lug thereon with nose 84- ot detent 33 and swing the latter about its pivot 81 against the tension of spring 37. Thereby car 35 is drawn from engagement with nose 29 of lever 25 and. said lever is drawn by the spring 30 along the cam face of arm 36 until brake element engages the governor disk. Owing to the coaction of nose 29 with the cam or inclined surface of arm 36, detent 33 is moved upwardly along its pivot pin 31-nntil nose 34 is freed from the lug or member 17 in engagement therewith, whereby said lug may pass by said nose. The controlling member 33 being thereby moved out of operative relation with the stop-actuating member, the latter is in position to make a half revolution upon again starting the machine and before the lugs on said member resume operative relationship with the lever 9 and member 33.

If it is desired to stop the machine prior to the automatic actuation thereof, or in case the automatic mechanism should not operate, the machine may be stopped by pressing inwardly on lever 4:6 until nose 49 engages detent 33 and moves the same about its pivot to release stop lever 25 in the manner just described.
