Application filed July 18,

and effective attachment which will cause the sound box and needle to be automatically swung over into its initialposition when it has reached the end of the record.

A further object is todevise a repeating device which can be adjusted to work with records of different sizes and a still further object is to devise a repeating dGVlCGWhlCh will be silent in operation.

My invention consists of a repeating device constructed and arranged all as, here1n after more particularly described and illustrated in the accompanying drawing in which I Fig. 1 represents a plan view of the record table, sound box'and tone arm showing my device applied thereto.

Fig. 2 is a side elevation thereof showing the'needle engaging the record and a portion of my device mounted on the sound box in the inoperative position, and Fig. 3 is a similar view to Figure 2 showing a portion of my device on the sound box in the operative position.

Like characters of reference indicate corresponding parts in the dilferent views.

1 is the record turntable/to which is removably secured the usual central spindle 2 adapted to be rotated in the usual manner.

3 is the sound box. 54 is the tone arm. 5 is the annular'plat'e in the-case of the gramophone through which the tone arm 4: extends.

51 is a bracket member suitably secured to the back face of the sound box and having pivoted to its lower end the arm 6 upon. the free end of which is journalled the wheel 7 which is preferably rubber-tired. 8 is a shoulder on the upper end of the arm 6 adapted to engage a corresponding shoulder 9 on the lower end of the bracket member 51 when the arm is swung into the position illustrated in Figure 3.

10 is a spring secured at one-end to the bracket 51 and at the other end to the arm 1922.- Serial No. 575,792.

6. 11 is a projection .on the free end of the arm 6.

12 is the needle mounted in the usual man- 7 ner in the socket 13 on the sound box.

1 1 is a hood member adapted. to extend over the spindle 2 above the record 15 and.

to be secured thereto by means of the setscrew 16. 17 is an arm extending transversely through the hood 14 above the spindle 2 and adaptedto be adjustably secured in position therein by means-of the setscrew 18. I

19 is an arm adjustably secured at one end to the plate5 by means of the headed stud 20 on such plate which extends through a slot 21 in the arm 19. 22 is a thumb screw journalled in the-bearing 23 on the top'of the machineand held against-displacement by the collars-2 1. 25 is a lug on' the held end of the arm 19 said lug being provided with the threaded orifice 26 adapted to receive'the screw 22. The free end of-the arm-is bent inwardly towards the spindle 2 -and provided with a hooked. member 27 pivoted thereto, one endof the hooked member 27 being provided with the buffer 28' andga spring 29 extending between the arm 19 and th hooked member 27 for normally holding the same in the required position. 1

My device operates as follows:

When the record is placed onthe turntable and the latter rotated thesound box the record is reached, when upon the" arm travels across the same in an inward direc- -t1on' 1n the usual. manner until the end of such arm will strike the-projection 11 on-the arm 6, causing'such arm and' wheel'7 to be swung downwardly into the position illustrated in Figure 3 wherein the wheel 7 will engage the record 15 and the needle will be raised off such record. Owing to centrifugal force the sound box when supported on the wheel which engages the record will be swung to its outermost position] wherein a buffer 30, provided on the forwa'rdlface of the sound-box,willengage the buffer28, thus F [swinging the hooked end of the hooked member 27 into engagement with the arm 6 swinging the latter into the inoperative position illustrated in Figure 2. The spring 10, which is distended when the arm 6 is moved into the position illustrated in Figure 3, will restore the arm to the position illustrated in Figure 2 when such arm is moved by the hooked member over the vertical centre linethus allowing the sound box to drop down until the needle engages the record. On desiring to adjust thev arm 19 to suit records of different sizes, it is merely necessary to rotate the thumb screw 22, which moves the arm through the medium of the lug 25 thereon into which the screw is threaded.

From the above description it will be seen that I have devised a simple and effective gramophone repeating device which can be readily applied to existing gramophones and which will be positive in use and moreover can be adjusted to operate on records of different' sizes.

lVhat I claim as my invention is.

1. In a gr'amophone' repeating device, the

combination with the sound box and record,

of a bracket secured to the sound box, an arm pivotally mounted on the bracket, a wheel oi'irnalled' onthe free end of the arm, the wheel engaging the record upon the arm being swung into the operative position and elevating the sound box with the consequent disengagement of the needle from the record, a shoul der'on the bracket and a shoulder on the arm engaging each other upon the arm being swung into the operative position.

2. In' a gramophone repeating device, the combination with the sound box and record, of a bracket secured to the sound box, an arm pivotally mounted on the bracket, a wheel journal'led on the free endof the arm, the

wheel engaging'the record upon the arm being swung into the operative position and elevating the sound box with the consequent disengagement of the needle from the record, a shoulder on the bracket and a shoulder on the arm engaging each other uponthe a rm' beingswungi nto the operative position and a spring secured to the bracket and its other end secured to the arm for normally retaining it in the upper or inoperative position.

3". In a gramophone repeating device, the combination with the sound box and record, of at swin able arm pivoted to the sound box, a rotatabIe member on the free end of said swingable arm adapted to engage the record upon being. thrown into the operative position and lift the needle out of engagement therewith by raising the sound box, a projectifon on the arm, means engaging the projeetion torswingingthe arm into the operative position andmeans engaging the arm for swinging it-into the inoperative position. 4. Ina gramophone repeating device, the

member engaging the arm. upon the sound box reaching the outer limit of its run.

5. In a gramophone repeating device, the combination with the sound box, record turn table spindle and record, of a swingable arm pivoted to the sound box, a rotatable memher on the free end of said swingable arm adapted to engage the record upon being thrown into the operative position and lift the needle out of engagement therewith by raising the sound box, a projection on the arm, an adjustable arm on the record turn table spindle adapted to engage the projection upon the sound box reaching the inner end of its run and a suitably supported adjust-able hook member engaging the arm I upon the sound box reaching the outer hm1t of its run.

6. In a gramophone repeating dev1ce,- the combination with the sound box, record turn table spindle and record, of needle disengaging means and a hood adapted to be secured to the top of the record turn table spindle. an arm adjustably secured to the hood adapted to engage the needle disengaging means for throwing the same into the operative position and an adjustably mounted arm having a hook shaped member adapted to engage the needle disengaging means and throwing it into the inoperative position, a buffer on the sound box adapted to engage the buffer on the hook member for actuating the same.

7. In a gramophone repeating device, the combination with the sound box, record turn table spindle and record, of needle disengaging means on the sound box, a buffer on the sound box, an adjustable arm, a spring-held hook member mounted on the adjustable arm, a buffer on the hook member, said buffer on the sound box adapted to engage therewith.
