To aZZ whom it may concern:

Be it known that I, CLINTON E. Wooos, of Bridgeport. Connecticut, have invented a new and useful Improvement in Start and Stop Mechanism for Talking -Ma-chines, whi h invention is fully set forth in the following specification.

This invention relates to start-ancl-stop mechanism especially designed for but not necessarily restricted to talking machines. In providing startandstop mechanism for talking machines, a variety of possible conditions have to be taken into consideration. The motor may be a continuously running motor, capable of being connected to, or dis connected from, the talking machine for starting and stopping the same; or, a motor such as an electric motor may be in constant operative relation'with the machine, and the current to the motor be switched on and off to start and stop the motor; or a spring-actuated motor may be in constant operative relation with the machine, and a sufficient resistance introduced at a suitable point in the mechanism to overcome the motor and stop the machine. which resistance being removed, permits the motor to start the machine. The object of the present in vention is to provide means whereby the talking machine shall normally be held stopped when the ire-producer is out of operative relation with the record-groove; whereby the talking machine shall be automatically started when the reproducer is placed in operative relation with the recordgroove, and whereby the talking machine shall continue to operate so long as the reproducer remains in operative relation with the record, but shall be stopped when the tone-arm. with its accompanying reproducer, is shifted to inoperative position, whether it be at the center or at the periphery of the record. A further object is to provide a simple and efficient device for accomplishing the results indicated above.

With this object in view, the invention consists, as in a ta king machine, of startand-stop mechanism therefor, a movable element or tone-arm, and means, as a cam, moving with said movable element or tone arm and positively actuating said start-and stop mechanism. Preferably, there is an arm connected with the movable element or tone-arm provided with two suitably spaced cams, either one of which is capable of being positioned to actuate the start and stop position to commence the reproduction of a record, the mechanism is automatically re leased, and the machine started, and it continues in operation until the tonearm is moved to a point (either at the center or the periphery of the record) where one of the cams again engages the start-and-stop mechanism. In case the .record is of sufficient length, the parts may be and sometimes are, so constructed that the record itself will advance the tone-arm sufiiciently near the center of the record-tablet to actuate the startand stop mechanism to stop the machine. Otherwise, the stoppingaction is effected by manually moving the tone-arm to the proper position.

The inventive idea involved is capable of receiving a variety of mechanical expressions, two of which, for the purpose of illustrating the invention, are shown in the ac companying drawings, one showing the application of the inventive idea to a structure embodying an electrical motor, and the other to a structure embodying a spring motor; but it is to be expressly understood that such drawings are for the purpose of illustration only, and are not designed to define the limits of the invention, reference being had to the appended claims for this purpose.

In said drawings,

Figure 1 is a top plan view, showing the start and--stop mechanism constituting the present invention, operating in association with a spring motor;

Fig. 2 is a similar view, showing the start-and stop mechanism operating in association with an electric motor;

Fig. 3 is a sid el a on, partly in sect-ion (some of the parts being broken away for the sake of clearness), showing the tone-arm, its mounting on a hollow support, and the connection between said tone=arm and the startand-stopmechanism; and

Figs. 4 and 5, are detail views.

Referring to the drawings, wherein like reference nun'ierals indicate like parts, is any suitable motor, whether spring or electric, secured in any usual or desired manner to the underside of a motor board 11. Said motor drives a vertical shaft 19, which passes through the motor board 11 and on which is mounted the usual turn table or record support (not shown). The motor board 11 is provided with aperforated car 13, preferably formed integrally therewith, on which car is mounted a hollow support 14: for the tone-arm. This support is provided with a flange 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 which the usual or any suitable sound-box is secured) and a vertical section 18, which, as here shown, is associated with a sound-deflector 18, though any suitable amplifying horn may be employed. \Vithin the vertical section 18 is preferably secured, to turn therewith, a sleeve 19 which projects down into the hol' low support 1% and is connected in any suitable manner to an arm 20 which is rotatable in a recess 21. in said hollow support 14. As here shown, the connection is effected through the intermediary of an annular member 2-2, provided at its upper end with a plurality of lugs 23 which engage in cor responding recesses in sleeve 19, and at its lowcrend with lugs 24 which engage corresponding recesses in arm 20. By this, or any other suitable connection between the -tone-arm and said lover, the movements of the former are transmitted to the latter, so that as the tone-arm is propelled across the record the arm 20 will be moved through th same angular distance. The starting and stop-ping of the motor are cont-rolled by the movements of the tone-arm operating through said arm 20, the latter acting to effectively perform this function, whether it is associated with an electrical motor 10, as indicated in Fig. 2, or with a spring motor 10, as indicated in Fig. 1.

Referring particularly to Figs. 2 and a, 26 is the usual electric plug connected to conductor 2i which conveys current to the electric motor 10, and 28 and 29 are conductors that lead to a suitable switch mechanism (not shown) contained in casing 29 rarried by casting 30 which is secured to the motor board in any suitable manner. The circuit to the motor is opened and closed at said switch by a movable element or terminal 31, which is operated from the arm 20, and which has bearing in an extension of said casting 3,0. hen the parts are in the position shown in Fig. 2. the terminal 31 has been moved inward to open the circuit, and when the terminal occupies the position shown in Fig. 4. the circuit through the motor is closed. The terminal is moved inward (in the present instance to open the circuit) against the tension of coiled spring 32, which reacts between a nut 33 and a pin 34; passing through the terminal; and is moved in, the opposite direction by said spring 352.

The particular form of means herein shown for operating said movable element or terminal 31 consists of two cam surfaces 35 and 36 formed on extensions 87 and 38 of said arm 20, incline 39 being associated with cam surface 35 and incline 4L0 with cam surface 36. Between these inclines is provided a cut-out portion 41. l l hen either cam surface 35 or 36 engages the end of the movable member or terminal 31, which latter is preferably provided with an anti-frictional roller l2, said element is moved to open the switch and stop the motor. VVhe n said roller 42 engages incline 39 or 40, said movable element moved by spring 32 to close the switch and start the motor and the mot-or continues to run while the cutout portion 41 passes the movable member, as shown in Fig. -l. The function of incline 3 and ll) is to control the compression and expansion of spring 32, so that its action will be gradual, and the mo! or will be started and stopped without violence or jarring, though none the less quickly and effectively.

Referring particularly to Figs. 1 and the present invention is shown as applied to a talking machine whi h is operated by a spring motor 10. The governor shaftis indicated by 4.3, and 514 is a friction disk keyed to said shaft. in thi the in entive idea. the movement of element 31. operates. by any suitable means, to press friction pads 45 against the friction disk with sufficient force to stop the motor. The particular means here shown consist of a crank 46,01 9, end of which engages the mova lo element '81, and the other end of which is securely fixed to the upper extremity of a sleeve 47 rotatable on a pin 48 secured in casting 30, the lower extremity of said sleeve carrying an arm 49 to the free end of which is secured a resilient member 50. This memcrnbodiment o ber bears against a lever 51 pivoted in brackets 5252, said lever carrying a frictionpad-supporting member 53 to which are secured aplurality of friction pads which, as heretofore stated, are pressed against friction disk 44 to stop the motor. The pads 45 are moved against the tension of spring 54L (F ig. 1) into engagement with disk ell to stop the motor. One end of said spring is secured to crank 46 and the other end is anchored to casting 30, said spring acting to remove the pads from the friction disk when the cam surfaces 35 and 36 are disengaged from roller 42.

The horizontal movement of the tone-arm is limited in any suitable manner; as'here shown (Fig. 3), the end of a screw 55, carried by the hollow support I l, engages in a slot 56 in sleeve 19 carried by the vertical section 18 of the tone-arm.

The operation of the device is as follows If the sound record is of suflicient length so that, when the reproduction is completed, the tone-arm shall have moved the arm 20 until the ram surface 36 has engaged the roller at), the motor will. be automatically stopped. On the other hand, if the record is a shorter one, so that the tone-arm does not move far enough to engage the cam surface 36 with roller 42, the motor may be stopped by manually moving the tone-arm the necessarv additional distance to engage surface 36 with roller 42. At this time, the tone-arm and the sound-box occupy the po sit-ion shown in dotted lines in Fig. 2, that to say, the sound-box is adjacent the centor of the record tablet. The motor is also stopped when cam surface 35 engages roller 4-2 and actuates movable member 31. This engagennent is effected by swinging the tonearm in the opposite direction to that in which it is; propelled by the sound-record. and until the pin 55 engages the end of slot 567 At this time the sound-box is clear of the record, and when it is desired to start the motor: the operator moves the sound-box and tone-arm inward until the stylus ongages the commencement of the record, at which time the roller has passed off of cam surface 35 and onto incline 39, thus permitting spring 52: (Fig. 1) or spring 32 (Fig. 2) to displace movable member 31 to close tl e circuit of the electric motor 10 or to withdraw from disk il: the friction pads 45 associated with the spring motor 10. hen the roller 42 reaches the inner end of incline 39, the movable member 31 has reached the limit of its movement toward the right- (Fig. 1 and said member continues in this position until incline ll) engages roller 42, when nmnber 31 is gradually forced toward the left against the tension of its associated spring. When cam surface 36, either manually or automatically, engages roller 42, as heretofore stated, the movable element 31 will have reached. the extremity of its movement toward the left, to the end that the circuit of the electric motor is opened or the friction pads 45 are pressed into stopping ongagement with friction disk 44.
