AUTOMATIC STOP FOR PHONOGRAPHS.

To all 107i om 1125 may concern Be it known that I, FRANCIS W. DOLIER, a citizen of the United States, residing in liloorestown, -in the county of Burlington. and State of N ew Jersey, have invented certain new and useful Improvements in Automatic. Stops for lhonographs, of which the following is aspeeification.

My invention relates to an automatic stop for a phonograph, graphophone, or other sound or voice reproducing;r apparatus.

lt is the object of my invention to provide simple and effectivel mechanical means for automatically stopping the movement of a sound record after the record has been traversed, completely or otherwise, by the reproducing stylus or needle; and it is more particularly the object of my inventionto provide apparatus for this purpose which dispenses altogether with any addition to or alteration of a sound record. ,To this end I have provided simple means for releasing or .setting a brake which brings the record moving system to rest.

My invention resides in the features hereinafter described and pointed out in the claims.

For an illustration of one of the forms my invention may take reference is to be had to the accompanying drawing, in which:

Figure 1 is a top plan view of a sound re- ]iroducing machine having my invention applied thereto. Fig. 2 is a sectional view, some parts in elevation, taken on the line 2-2 of Fig. 1. Fig. 3 is a horizontal fragmentary sectional view, some parts in plan, taken on the line 3 3 of Fig. 2. Fig. 4 is a cross sectional view, some parts in elevation, taken on the line 1- L1 of Fig.2. Fig. 5 is a cross sectional View, parts in elevation, on the line 5-5 of Fig. 2. Fig. 6 is a fragmentary side elevational. view of part of the setting or adjusting apparatus.

Referring to the drawing, 1 is a suitablev base, such as the top of the usual box inclosing the motor for driving the sound record. The sound record 2, here shown by way of example, as being of the disk form, though it may be of any suitable form, rests upon the felt or other suitable material 3 which in turn is disposed upon the platen or turn table which isx driven in the usual way by the shaft 5 of the driving motor.

The usual hollow sound transmitting arm 6, part of which has been omitted, is movable about aivertieabaxis on a bracketLl'not Specification of Letters Pat-ent.

example,

shown, secured to the motor box. Attached to the arm 6 is the hollow bend 7 communieating with'the interior of the arm 6 and with the sound box-S carried on the end of Patented Apr. 13, 1915. Application flied January 14, 1913. Serial No. 741,955.

the member 7, the member 7 having pivotal i movement about a horizontal axis upon the member 6, as is wel] understood in this art. The sound box S carries the usual reproducing needle or stylus 9 which engages the record 2 asthe latter revolves. In moving from the ciroiiinfereiice of the record 2 toward the center, in traversing the successive spirals in the record, the stylus 9 swings in an arc Whose center is the pivotal aXis of the arm 6.

On one corner of the base of top l 'is mounted the usual manual brake comprising the brake shoe 10 which is adapted to engage the peripheral or outer surface 11 of the platen 4 to bring the saine to rest.

The

shoe 10 is released, as well understood in the art, by the clockwise movement of the hand lever 12, as viewed in Fig. 1 about its pivot, which movement releases the brake shoe to the control of a spring, which spring presses the shoe against the surface 11. And movement 0fthe lever 12 in counter-clockwise direction withdraws the brake shoe and holds it withdrawn.

Secured to or integral with the post 13 is the arm 14: free of and across and above the sound record 2. The post 13 is secured to the base 1 by the bolt 15 which may be tightened to such degree as to produce suflicient friction between the post 13 and the base 1 to cause the arm 14, for the purpose of this invention, to remain in any position to which it may be shifted about the bolt 15 as a center. .'l`he'arin'14'may be of any suitable shape, but it is here shown, by Way of as of channel section. Near its outer end it carries a block 16 pivoted at 17 to the arm 14, so that the block 16 may move upon a vertical axis with respect to the arm 14E. Within the block 16 there is pivoted at 18 the rod 19 movable about the horizontal axis formed by the pivot 18. At its inner end the rod 19 has a pivot 2 0 upon which is Y supported the pin 21. The lower end of the .Zontal pivot 18. As seen in Fig. 3, the pin 21 is normally out of alinement with the hole 25. The movement of the pin'21 into the hole 25- accompanies the pivotal movement of the block 16 about its vertical pivot v17.

At 26a there is a web extending trans- .ver'sely to the channel 14, such web having an inclined edge 27, as indicated in Fig. 5.

Pivoted at 28 to thJ under side of the platen 4 is the member 29 having the downwardly extending cheek 30 adapted to engage the inner side of the flange 4a ofy the platen 4, being held normally in such position by the spring 31 secured at its one end to the flange 4al and engaging with its outer end thexmember 29. Extending under the lower edge of the flange 4El is the lug 32 secured to or integral with the cheek 30, the lug 32 extending out beyond the periphery of the flange 41and as the platen. 4 revolves passes through the space or slot 26.

Pivoted at 33 to the base 1 is the lever 34 Whose outer end is connected by link or" other connecting means 35 with the hand lever 12 of the brake releasing mechanism. At 36 the lever 34 has an upwardly extending llange which is adapted to be engaged,

under circumstances hereinafter' explained, by the flange 3() upon the member 29.

To the sound box 8 is secured a projection or lug 38 adapted to engage the outer end paf the rod 19 as indicated by dotted lines in i 1. 'The operation is as follows: The sound record 2, which need be in no respect altered for service with this braking apparatus, is placed in position upon the platen 4 inthe well known manner. When the motor has been started the stylusv traverses the sound recordV causing the reproduction of sound in the well known way. When the -selection has been completely reproduced,

`the lug 38 engages the rod 19 shifting it in counter-clockwise direction about its ivot 17, as viewed in Fig. 1, carr ing the pm 21 from 'its normal position in icated in Figs. 1, 2, and 3 into alinement with vthe hole 25 whereupon the pin21 dropsv into. the space or slot 26, the-`rod.19 movin uponl its

horizontal pivot

1,8 during this dropping movement. The lug 32, .whichnormally passed freely throu gh the slot 26, now engages the pin 21 causin the flange 37 to move inwardly about its ivot 28 in opposition to' spring 31, and whi e so4 held inwardly by the pin-21 the flange 37 engages the flange 36 upon the lever 34 causing a clockwise movement of the lever 34 about its pivot 33 as viewedin Fig. 1. This causes a pull to be transmitted to the lever 12 throughtlie connection 35 with the result that the brake-is tripped or released or set and the shoe 10 engages the platen 4 stopping the sound recordmoving system. When a new record has been placed upon the platen the sound box may be moved manuali center of the record until stylus 9 is in the last sound reproducinggrooveof the record. Then the arm 14 1s swung upon its pivot 15 to bring the rod 19 near or against the lug 38. Then the stylus is returned to the start of the record. Then by pushing downwardly on the outer end ofthe rod 19 the pin 21 will be lifted out of the hole'25 and as the lower end of the pin 2l clears the upper surface of the lug 24 the rod 19 engages the' inclined surface 27 of the web 26 and the continued downward movement of the outer end of the rod 19 is accompanied by a lateral movement of the rod 19 about its pivot 17 carrying the piii 21 to one side of the hole 25 to its -normal position as indicated in Figs. 1, 2, and 3. Then upon the traverse of the record by the stylus the brake is again applied as described.

Ii desired a pointer 39 may be provided upon the member 40 pivoted at 41 to the arm 14. Backof the pivot 41. the member 40 is provided with a lug 42 extending under the lowerA edge oi the arm 14 and beneath the rod 19. The rear end of the member 40 back of the pivot 41 may be made heavier than the forward end carrying the needlet'i soy that normally the needle or pointer 39 is' raised from the record 2; or the arrangement mayl be such that the pointer 39 can in no case come into actual contact ,with the record 2.

This device may be used to position the arm 14 without manually moving the sound boX 8 across the record for purposes cf setting the arm 14. Thus, when a record has been put in position, the pointer 39 may be brought to the last sound record groove in the record and the forward end of member 40 depressed to bring the pointer 39 into such groove. This properly locates the armI 14. This depression of the member 40 will cause the lug 42 to lift the rod 19, which has dropped due to the braking of the previous record, lifting the pin 21 free of the hole -less accuracy. But the accuracy will be 'still greater if the pvot 15 of the arm 14 were 'on the other side of the sound record, that is, near the top of Fig. 1, for then the arm 14 and the arm 6 would be more nearly concentricallyk pivoted. In such case the memover toward the maaien ber l0 would be pivoted on the that is, the left hand edge, ber le.
