TALKING-MACHINE STOP;

Specification of Letters Patent;

Patented May 7, 1913.

Application filed August 7, 1916. Serial No. 113,583.

To all whom it may concern: Be it known that I, QHARLIEJ. Bons- FIELD, a citizen of the United States of America, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Talking-Machine Stops, of which the following is a specification.

This invention relates to talking machine stops.

One object of my invention is to produce a positive and simple device which will automatically stop the talking machinemechanism at any point desired, during the travel of the tone arm across the sound record.

Another object resides in the provision of means under the control of the operator whereby the device may be set to stopthe mechanism at any point during the travel of the tone arm across the sound record.

With the above and other objects in view,

the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing, and particularly pointed out in the appended claims, it being understood that changes may be madein form, size and minor details without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawings:

Figure 1 is a plan view of my device showing the mechanism out of operative engagement.

' Fig. 2 is a side elevation of the same.

Fig- 3 is an isometric view showing a slight constructive difference "over that shown in Fig. 1.

In the drawings, 1 is the top of a talking machine cabinet upon which is mounted a I turntable 2 adapted to carry a sound record from thelower part of'the tone arm 4 1s a lug 6, for apurpose to bepresently explained. v I

A plate 7 is pivoted to the casing at 9, said plate by the same pivot 9, is an operating lever 10 having an enlarged portion 11 at its inner end. Two

upturned ears 27 are formed at adjacent *sides of the enlarged portion of the lever 10, which serve to limit the stroke of the lever 10. A helical spring 12 has one end attached to oneear 27 of the enlarged portion 11 of thelever 10, its other end being secured to an ear 23 formed at one side of the plate member 7 This spring has a tendency to normally throw the outer end of the lever-10 into engagement with the lug 6 of the tone arm a. A fiat spring 13 is attached at one end to the upper side of the plate 7 by means of a rivet 28 which is formed with a raised head; The opposite end of the spring 13 isbent up and secured to theunder side of a lever 11, which tends to draw the inner end of the lever 1 1 downwardly upon the enlarged portion 11 of the lever 10. The raised head of the rivet 28 serves as a fulcrum upon which the lever 14 is adapted to be rocked.

The inner end of the lever 1 1 overlaps the enlarged portion 11. of the lever 10, as shown at 14: and by reason of the spring 13 pulling downwardly on the under side of the inner end of the lever 14. the end 1 1 is held in frictional contact with the said enlarged portion 11 of the lever 10. It will and at its inner end, on one side of the pivot 19, is provided a receiving notch 20 for the reception of a lug 21 projecting from the edge of the plate 7. A spring 22 has one end attached to the inner end of the lever 18 on the opposite side of the pivot 19, and its other end attached to the lug 23 projecting from the opposite edge of the plate 7 The spring 22 normally has a tendency to pull the lever 18 to the left to the stopping position,but is held from doing this by the engagement of the log 21 with the notch 20 i when the parts are in operative position;

*A stop 24 is attached to the casing for limiting the movement of the plate 7.

In the operation of my device the tone arm 4 is first moved to the point on the record at -which it is desired to stop the operating mechanism and the travel of the tone arm, then by pressing down on the thumb rest 17, the end 14 of the lever 14 is moved away normal position and the end le of. the lever 14 will frictionally hold thelever 10 in its adjusted position. The tone arm is then swung onto the first line of the sound record (as shown in dotted lines of Fig. l) and the mechanism started by moving lever 18 to the right, whereby the lug 21 will be received in.

the notch 20 thereby holdin said controlling lever 18 in its starting position against the tension of the spring The tone arm will thus start moving across the record toward the center thereof. Upon the tone arm reaching the point at which it is desired to stop the mechanism, the lug 6 of the tone arm will engage the outer end of the lever 10 thus swinging the lever 10 and consequently the plate '7 and second lever 14L about the pivot 9 until the stop 2-l prevents further movement. This releases the lug 21 from the notch 20 whereby the spring 22 will move the lever 18 to the left and stop the mechanism.

In Fig. 3 a slight modification of my device is illustrated. In this figure the plate 7 has a pair of upturned ears 8 at adjacent sides thereof, while the lever 1 1 has a simi' lar pair of downwardly turned cars 15 which are adapted to fit between the upturned ears 8. The two pairs of ears are pivoted together by means of the pivot pin 16. A fiat spring 13 is attached to the upper side of the plate 7, the free end of said spring being curved and then pressing upwardly against the outer end or the under side of the lever 1%, thereby normally placing the opposite end in of said lever 1% into frictional contact with the enlarged end 11 of the lever 10, thus holding said lever 10 in any position to which it may be adjusted. The rest of the elements in this figure are the same as those illustrated in Figs. 1 and 2.
