START .ANDVSTOIP MECHANISM FOR TALKIG-MeCI-IINES.

Lacasse. i

Application filed ctober 15, 1913,v Serial chilies, and is designed more particularly7i for use. in connection with that class of talking machines in which a tone-arm or other tubular sound-conductor, together with the reproducer, is advanced across the face of a disk record in the act of reproducing said record. With said devices the machlne' is automatically started when the operator places the reproducer and tone-arm in position to commence reproduction and automatically stopped when, for any reason, the reproducer and tone-arm cease their advance movement across the face of the record.

One of the objects of the present invention is to provide a startandstop mechanism which willbe highly eiiicient in operation and will operate equally well however the diderent records reproduced may vary in the number of threads to the inch.

An objection to the start-andstop mecha nisms at present employed is that, after the tone-arm comes tol rest, the sound record is not promptly stopped but continues to rotate, sometimes fifteen or twenty times, be fore the machine is stopped, thus prolonging the disagreeable scraping sound of the stylus on the record; and by the present invention it. is sought to obviate this objectionable feature by promptly stopping the motor after the tone-arm has ceased to move.

YVith machines employing start-and-stop mechanism connected to and controlled by the tone-arm, it has heretofore been necessary to exercise care in manually moving the tone-arm to prevent injury to the parts;

and it is a further object of the present inlvention to provide a device which will obviate this objection and which is so simple and durable in construction as t0 practically eliminate the chance of injury bycareless handling. Brieiiy stated` the invention consists. generally, in providing a record support across` Specification of Letters Patent.

which the tone-arm is propelled, and in introducing between the tone-arm .and motor two movable members, one connected tothe tone-arm and the other to the motor,v` said,l members normally moving at substantially the same speed. These members engage and operate a third member which is 'normally held in position to permit the motor to run, but which thirdjmember is moved to elit'ect the stopping of the machine when one of' said first two members ceases to move, or its speed of movement is materially varied, 'as

by decreasing below a-predetermined limit,- In the preferred embodiment of the inventive idea illustrated herein, a dierentiajl gearing is introduced between -the motor and the tone-arm, this gearing, as herein shown, preferably 'consisting of two bevel. gears, one driven from the tone-arm and the. other from the motor. Normally they ro tate at substantially the same 4Speed in op- ,4

posite directions, and mesh with and rotate a bevel pinion, the movement of which latter y operates, through suitable connections, to stop the machine when one of said bevel gears ceases to rotate.

The invention will be better understoodV by reference to the accompanying drawings, illustrating one expression of theinventive idea, and wherein- Figure 1 is a top plan viewishowing the start-and-stop mechanism constituting the present invention, operating in association with an electric motor;

Fig. 2 is a vertical elevation of the mechanism shown in Fig. 1; 1 4.

Fig. 3 is a view similar vto Fig. l, showing the start-and-stop mechanism operating' in association with a spring motor;

Fig. Ltis a detail elevation, partlyin section, showing the slip connection between the pinion that mesheswith the rack one the lever arm (connected to the .tone-arm) and'. its associatedbevel gear; i -z Fi 5 is a detached perspective, view, showing the start and stop v mechanism;

Fig. '6 is a vertical sectionthrough said mechanism; and

secured in any usual or desired mannerto of a motor-board 11: Said,- i

motor drives a vertical shaft 12 which passes through the motor-board on which is mounted the usual turn-table or record support 13 (Fig. @2). The motor-board is provided ed a hollow support 15 .for the ltone-arm.

This support is provided with afiiange 15 which rests on the ear, and an extension 16 that passes through the perforation in the ear in snug engagement therewith.

The tone-arm is preferably composed of a horizontal section 17 (to which4 the usual or any suitable sound-box is secured), and a vertical section 18 which, as here shown, is associated with the sound delector 18, though any suitable amplifying horn' may 'be employed. Vithin the vert-ical section 18 is preferably secured', to turn therewith, an annular member 19 provided at its upper end with a pluralityof lugs which engage in corresponding recesses in section 18, and at its lower end 'with lugs which engage corresponding'recesses 20 (Fig. 5) in a con* nectmg arm 2l which 1s rotatable m a re cess 22 in saidextension 16. By this, or any other suitable connection between the tone-arm andsaid connecting arm 21, the movements of the tone-arm are transmitted `to 'the connecting arm so that as the tonearm is propelled across the record, the con necting arm 21. will be moved through the Same` angular distance. The 'starting and e movements of the tone-arm operating through said connecting arm 21, the latter acting to effectively perform its function,

whether it is associated with an electric motor 1G, as indicated in Fig. 1, or with a spring` motor l0', as indicated in Fig. 3.

Referring particularly t0 Fig. 1, 23 is the usualelectric plug connected to conductor 24 which conveys current to Athe electric motor 10, and. and 26 are conductors that lead to a sultable switch mechanism (not shown) contained in 'casing 27 carried bv theI casting 28 which is secured to the motor-board in any suitable manner, as by a plurality of bolts29 (Fig. `2). The circuit to the motor is opened and closed at said switch by a movable element or terminal 31 which is carried in a sleeve 32 (Fig. (i) connected to the switch casing, said terminal being under the tension of a 'spring 33, the tendencyr of which is to force said terminal ton'fard the right. This terminal is provided, preferably in its underside, with an inverted V-shaped notch 34 for a purpose which will hereinafter be described, and is slotted, at 35, to accommodate a pin 361 mounted in sleeve 32, which pin prevents the terminal 31 from rotating.` .The free end of said terminal is preferably provided with an stopping of the machine are controlled by 1 35 th Lacasse vthat position by the engagement in notch 34 of a latch 40carried by a pin 41 (F ig. 5) having bearings in housing 42 which is prei-`- 'erably integral with the casting 28. It is through openings in the side walls ol this housing that projects sleeve 32 carrying the terminal or plunger 31. The latch 40 has one end of a spring 43 connected thereto, the other end of said spring being anchored in said housing 42, said spring acting` to withdraw the latch 40 from the inverted V- shaped notch 34.

When the parts are in the position shown in Figs. 5 and G, itfwill'be observed that latch 40 is held in engagement with notch 34 (to maintain the plunger or terminal 31 in position to permit the machine to operate) by the engagement with the nose of said latch of the beveled end of a pin 44, the other end of said pin being provided with an eye 45 which loosely encircles a rod 4G. The upper `beveled end of this pin projects through a slot 44 (Fig. 5) in the, bottom of housing 42, for the purpose of limiting the movement of said pin around rod 4o, the inner or right hand end of said slot (Fig.A 5) acting as a stop for the pin 44 so that said pin, while holding latch 40 firmly in engagement with the V-shaped notch 34, cannot move vso far as to jam against said Then said dog 38 engages llo latch or to oiier any considerable resistance to its movement from under the latch at the proper time. This pin carries a bevel pinion 47 which is loosely mounted thereon, said pinion being held in place by collar 48 keyed to saidA pin. The bevel pinion meshes with a bevel gear 49 which is also loosely mounted on' rodf46, said pinion 49 being provided with a hub 50 (Fig. (i) which projects through an opening in the side 51 of a casing which is provided with {ianges 52 and 53. When the parts are in assembled position, flange (Fig. 5) is secured to flange 54 on boxing 42 by any suitable means, as screws 55, flange 53 being also secured t0 the bottom of said boxing.

The hub 50 is keyed to the hub of an annular member 56 also loosely mounted on rod 46, to which member is tiXedly secured, as by a key 57, a plate 58 (Figs. 4v and 6) provided ,with a plurality of tapering slots 59 (here shown as three), each of which slots carries a roller G0, which rollers cngage a pinion 61 which meshes with a rack 6,2 provided on a downwardly extending member 63, preferably integrally connected to connecting arm 21. A plate 64engages wall attract the face of pinion 61 and plate 58, and a nut 65 is screwed onto the end of rod 46 and holds the parts in the position shown in Fig. 6. Through these connections, bevel gear 49 is rotated in a clockwise direction when the tone-arm is being propelled across the sound record, during reproduction. When the tone-arm is being manually. returned to starting position, the bevel gear 49 is not rotated, for the reason that the pinion 61, as it rotates in a counter-clockwise direction, moves the rollers 60 from the smaller ends of slots 59 into the larger ends thereof, where said rollers idly rotate, none of the movement of pinion 61 being at this time transmitted to its associated parts.l When, however, the pinion 61 is rotated in a clockwise direction by engagement therewith of rack 62, said pinion will walk the rollers 60 in the same direction and force them into the tapered ends of slots 59, whereupon the plate 58 .and bevel gear 49 will be rotated in a clockwise direction.

The bevel pinion 47 meshes with a second bevel gear 66 Which is identical with bevel gear 49, said gear 66 being driven from the motor, through suitable connections, at substantially the same speed of rotation as said gear 49, but in a direction opposite to that 'of gear 49. Referring particularly to Figs. 2 and 6, 67 indicates a worm mounted on vertical shaft 12, which worm meshes with a Worm-gear 68 mounted on one end of a shaft 69 which has bearings in lugs 70, 71, preferably integrally formed with casting 28. The other end of said shaft 69 carries a pinion 72 which mesheswith a gear4 73 loosely mounted on a collar 74 which turns freely on rod 46, said collar being keyed to the hub of bevel gear 66. For a purpose to be hereinafter described, a friction-drive is provided between gear 73 and bevel gear 66, and as here shown, a steel disk 75 and a rubber disk 76 secured thereto are fxedly mounted on said sleeve 74, the steel disk 75 engaging one face of gear 73. The other face of gear 73 is preferably engaged by a steel plate 77 fixed to sleeve 74, the parts being held in position by nuts 78 and 79.

When the parts are in the position shown in Figs. 5 and 6, the bevel gears 49 and 66 are rotating at substantially the same speed in opposite directions, and inasmuch as they both mesh with bevel pinion 47, the latter is rotated on its axis, andreproduction is being effected. Any difference in the speed of rotation of gears`49 and 66 will be in favor of the former, in order to hold vpin 44 securely against theend 4of slot 44 and iii-engagement with latch 40. When the tone-,arm ceases its movement, as, for example, when it reaches the end of the record, bevel gear 49, which is driven therefrom, rwill also cease rotating, Whereas bevel gear'66 being driven froml the motor will continue to rotate. The continued rotation of bevel gear 66 will not only cause pinion 47 to rotate around its axis, but will also' cause member 44 to rotate around rod 46, thus removing the beveled en'd of said member from engagement with the nose of latch 40, whereupon spring 43 will withdraw latch 40 from inverted V-shaped notch 34 in plunger or terminal 31. Spring 33 will promptly force plunger 31 toward the right and into the position indicated in Fig. A2, whereupon (if an electric motor is employed) the circuit to the motor will be opened and the machine stopped or, if a spring motor is employed, the plunger 31 will act through suitable connections to apply the usual friction pads to stop the machine. f

lln Figs. 3 and 5, the present invention is shown as applied to a talking machine which vis operated by such a spring motor 10. Referring to Fig. 3, 80 indicates the governor shaft, and 81 a friction disk keyed to said shaft. In this embodimentof the inventive idea, the movement toward the left of plunger or terminal 31 operates, by any suitable means, to remove friction pads 82 from the friction disk to permit the machine to start,l whereas the movement of said terminal or plunger toward the right in Fig. 3 operates to press the friction pads 82 against friction disk 8l to stop the machine. The particular means here shown consists of a lever 83, one end of which en-. gages the movable element or terminal 31, and the other end of which is securely fixed to the upper extremity of a sleeve 84 (Fig. 5) rotatable on a pin 85 secured in casting 28, the lower extremity of said sleeve carrying an arm 86, to the free end of which isv secured a resilient member 87.l This member bears against a downwardly projecting i arm 88 carriedby a rod 89suitably mounted in brackets 90, said rod carrying a friction pad-supporting-member 91, to which is secured a plurality of Vfriction pads 82 which, as heretofore stated, are pressed against friction disk 81 to stop the motor.

As will be seen, the pads 82 aremoved into engagement with disk 81 by the tensionvof 11,5.- spring 92.

ment of the stylus with the record-groove,

and accordingly bevel gear 49 is rotated in va clock-,Wise direction by reason of 4the engagement between the rack 62 carried by connecting arm 21 and vpinion 61. AAt the 125 same time, bevel gear 66 is being driven from the motor in a counter-clock-wise direction, but substantially at the same speed as that of gear 49,'theaction of said bevel gears 49and 66 being to rotate bevel pinion 47 130 on its axis, and to maintain the parts in the position shown in Figs. 5 and 6. When the movement of the tone-arm across the record ceases for any reason, as for example, when theend of the record` is reached, bevel gear 49 at once, ceasesv to rotate, but thecounterclock-Wise movement of bevel `gear 66 continues. This continued rotation of. bevel gear 66 not only causes pinion 47 to rotate on its axis in a counter-clock-Wise direction, but, by reason of the fact that it meshes With stationarybevel gear 49, said pinion 47 be- 1 gins to Walk around bevel gear 49, thus removing the end of pin 44 from under the nose of latch 40. The bevel gear 49 thus serves as an abutment against which the pinion 47 reactsL When power is applied bythe gear 66. Spring `43 immediately Withdrawsvlatch 4Q"from the inverted \lshaped notch 34 in plunger 31, whereupon spring 33 forces said plun er toward the right, and, through connections heretofore described, efects the stopping ofthe machine. It will also be apparent that, if the speed of one j Lacasse is beipg rotated in a clock-Wise direction, f

this action of' the bevel` gears causin bevel pinion-47 'to rotate on its axis, and tie end of pin=44 to beheld in env agement with the nose of latch 40. It Wil be observed that 'dog 38 readily passes beyond plunger 31, as

"shown in Fig. 3, and, as heretofore stated, it v can, by 'reason of its yielding mounting, read ily return tothe position shown in Fig. l..

It frequently happens that after the reproduction of a record is started, it is desired to have only the .last part thereof rcproduced, and often the Operator Will rapidly move the tone-arm across the record to the desired point. In machines heretofore employing sta1t-andstop mechanism operated from the tone-arm, such of the bevel gears, 49 and 66, be inateriallyftlltmeni W35 liable t0 094115e injury: but

varied with respect to the other, the same operation will result. Thus, if thespeed of rotation of bevel gear 49 be materially decreased, as by a material decrease in the speed of traverse of the tone-arm, the more rapid rotation of bevel gear 66 Will cause pinion 47. to Walk around gear 49, removing` the beveled end of member 44 from engagement with the latch, whereby plunger 31 Will be actuated to stop the machine.

When it is desired to. restart the machine,

y the tone-arxn is moved to the position indicated in Fig.` 1', dog 38 as. it passes roller 37 moving around its pivot and away from stop v39. As heretofore stated, it is only when ear 61 is rotated lin a clock-Wise direction t at bevel gear 49 is rotated at all, the return move-ment of the tone-arm to the starting position acting to rotate only gear 61, which has a slip connection (in the form `of rollers 'with plate 58. l

When the parts are in the position shown in Fig. 1, the `beveled end of pin 44 is out of operative engagement with the nose of the latch 40, and as the tone-arm is brought to the starting position, the rack on armf21 engages the pinion 61 substantially at the instant dog 38 engages roller 37. The first efect of the rotation of pinion 61 by the rack is to cause a clock-Wise rota-tion of bevel gear 49, which not only imparts rotation to bevel pinion 47, but also Walks the saine around bevel gear 66, Which at that time is. stationary, this rotation of the bevel p1n-I Yion 4'? continuing until the parts are` in the l position shown in Figs. 5 and 6. As the flat face of dog 38 presses upon'roller 37 (Fig.

Il), plunger 31 is forced tothe left, and the movement ofthe parts is to timed thatvthe invertedv V.shaped notchy 34 will come oppo- .by the present construction, the liability of damageby-reasonof rough usage is prac- '.tically eliminated. vUnder the conditions above supposed, it is pointed out that the frictiondrive between gear 73 and disk 75 acts to,- prevent the speeded rotation of the bevel gears 49 and 66 (caused by the rapid movement of the tone-arn1 across-.the record by' the operator) from being transmitted to the motor, thereby eliminating the dan- .ger of breakage to the mechanism due to this cause.` Further, such speeded rotation of the gears which would tend to jam lpin 44 against the nose of latch 40 with undue force, cannot have this effect for the reason that after such pin 44 reaches the end of slot 44 (Fig. 5) it cannot be further moved.4

40 and spring 43, and to permit the parte contained in, said boxin be readily inspected an oiled.

and casing 51 to Not only can the device of the present invention be constructed at a fraction of the cost of start-and-stop mechanisms heretofore used, but it is highly eli'ective inoperation, and, so far asthe eliciency of the device is concerned, it is-'immaterial that the number of threads to the inch on different records to be reproduced ma vary largely'. Further, by theldeviceof tie present invention, vthe machine is ,promptly stopped after the tone-arm ceases its movement across the record. ln addition to this, the device is so simple and durable in construction as to practically eliminate the chance of injury by careless handling.'
