STOP FOR TALKING-MACHINES.

Specification of Letters Patent.

Patented Mar. 12, 1918.

Application filed June 22, 1917. Serial No. 176,370.

To all whom it may concern:

Be it known that I, J AMES S. LANE, a citizen of the United States, residing at Snohomish, in the county of Snohomish, State of iVashington, have invented a new and useful Stop for Talking-Machines; and I do herethe tone or sound arm for stopping the turn table that supports the record.

A further object of the invention is the provision of a device of this kind having an oscillatory spring tension frame or bracket mounted upon a plate and provided with a screw to be adjusted according to graduations upon a dial, whereby, as the stylus or needle reaches the end of the sound groove of the record, the tone or sound arm will engage the end of the abutment screw and cause the frame or bracket to oscillate incident to the tension of its spring, thereby applying a buffer to the turn table for stopping the same.

A further object of the invention is the provision of a dial and an abutment screw threaded through itscenter, and having an arm to overlie and register with any one of the graduations of the dial in accordance with the ending of the sound groove of the record, whereby thetone arm may contact with said screw tooscillate said frame or bracket. This abutment screw may be provided with any number of threads, each of any suitable pitch in accordance with the graduations of the-dial and vice versa. In other words, the graduations of the dial may be varied according to the pitch and the number of threads.

In practical fields, the details of construc tion may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown inthe drawings and claimed.

In the drawings Figure 1 is a plan view of a portion of a talking machine, showing the improved stopping device applied, whereby thetone or sound arm may automatically actuate the stopping device.

Fig. 2 is a plan view showing the stopping device as having been actuated.

Fig. 8 is a view in side elevation of the stopping device, showing the same on an enlarged scale.

' Fig. 4 is a view in elevation at right angles to that illustrated in Fig. 3.

Referring more especially to the drawmgs, 1 designates a portion of the casing of a talking machine, and in which casing the motor, not shown, for driving the record supporting turn table 2 is designed to be arranged. Swiveled in a conventional man nor on the casing 1, whereby it may oscillate across the record is a conventional form of tone or sound arm 3, which is provided with the usual coupled vertically oscillatory section 4 which is supplied with the sound box 5 having the stylus or needle 6. A partial circular supporting plate 7 is provided, the same having laterally extending perforated ears 8. Said ears are bent downwardly so as to hold said plate spaced at an interval above the casing 1, there being suitable screws 9 passing through .the perforations of the ears, to fasten the plate firmly to the casing. The center of the plate 7 has a perforation or aperture 10, for the reception of a pivot bolt 11, the head of which is arranged between the plate 7 and the upper face of the casing. This bolt 11 passes centrally through the circular base 12 of the oscillatory bracket 13, there being a suitable washer or circular plate 14 interposed between the base 12 and the plate 7, thereby holding the base of the bracket spaced fromthe plate 7. These interengaging parts may be well lubricated, so that the bracket will easily and freely oscillate a limited distance. Projecting from the marginal edge of the circular base of the bracket is a projection 15, the end of which is provided with oppositely disposed upwardly extending long and

short arms

16 and 17. The long arm 16 has at its upper end an overhanging curved hook is, to be engaged by an operators finger for resetting the oscillatory frame or bracket. The short arm 16 is provi'dedwith a substantially key-hole shaped slot- '19, in the larger end of which a suit- V able buffer 20, constructed of any suitable fiber, either leather or rubber, adapted to engage the marginal edge of the turn table 2, to stop the same, as the stylus or needle 6 reaches the end of the sound groove of the record. A'nut '21 is threaded" on the upper end of the bolt 11, to hold the circular base of the bracket or frame "on the bolt. Rising upwardly from the plate 7 is a'lug 22, and rising upwardly from the edge of the projection 15 ot" the base .of the bracket is a lug 23. Connecting the upper ends of the lugs 22 and :23 is a tension spring 2 l,'which, when the bracket or frame is disposed as in Fig. 1 with the buffer out of coin tact with the; turntable, contacts slightly to one side of the center of the bolt 11, so as to hold the bufler out of contact with the table. However, when the frame or'bracket is tilted to the position shown in Fig. 2, the spring '24 contracts slightly on the opposite side of the center of the bolt 11, thereby holding the butter frictionally in contact with the turn table and acting to stop the same. The circular base 12 of the frame or bracket, adjacent its marginal edge, is pro- -vided with .a cut-away portion 25 having

shoulders

26 and 27 at the ends of the-cut- 'awa ortion. The luv 22 is dis osed so as y P 2: l

IO play between the

shoulders

26 and 27 of said lug, provided the record supporting table "be removed,"when the spring 24 has contracted on .theside of the bolt 11 nearest the table supporting spindle. However, as long as the table 22 remains :in place, the shoulder 26 remains out of contactwit'h the lug'22. Extending upwardly from the circu'lar base of thebrac'ket or frame, is an upstanding arm'28 having a right angle extending portion 29, which is provided with an upright disposed disk .30. having a dial 31 on one face. An abutment screw 32 has its shank 33 (which maybe provided with any suitable number and pitch of threads) threaded through'the centerof the :disk .30. The screwshank is provided with a reduced part 34 on which a collar 35 is mounted. A

knurled head 36 is threaded on the reduced part 134:, to hold the collar 35 closely in contact with the shoulder 37 at the point where I the reduced part 34 axially extends 'from th'efscrewr EThe collar-35in its wall has an fopening 38, "in which the angular arm or :inernber 39 is secured in any "suitable man- ";ner.

The'predetermined graduations, according to the various records, having been ascertained, the record'is placed upon the turn table and v the screw .32 adjusted, so that the lateral portion 40 of the arm 39 may be arranged accordingly. The tone arm is then placed so t hat the stylus or needlemay follow'the soundgroove, and when the needle reaches the end of the groove according to the predetermined graduation, the tone arm simultaneously contacts with the abutment screw,
