To all whom it may concern:

Be it known that I, LYMAN D. KELLEY, a

subject of the King of England, residing at Memphis, in the county. of Shelby and State of Tennessee, have invented a new and useful Phonograph Repeating Attachment, of which the following is aspecification.

The principal object of the present invention is to-providea device of simple construction for automatically effecting the repetition of reproductions of the records ofphonographs and similar machines.

A further object of the invention is to provide a'device of this class which may be attached to anyordinary phonograph and in which provision is made for effecting very accurate ad'ustment in accordance with the starting an stopping positions of the record.

A still further object of the invention is to provide a device of this type which will automatically operate to restore the sound box carriage to initial osition after the completion of each repro uction so long as there is sufficient motive ower to run themachine- With these an other objects in view, as will more fully hereinafter a pear, the invention consists in certain nove featuresof construction and arrangement of parts hereinafter fully described, illustrated in the accom anying drawings, and particularly. pointe out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirili or sacrificing any of the advantages of the invention.

. In the accompan 'ng drawings, Figure 1 is ,a front elevation of a repeating device constructed in accordance with the invention, showing the same applied to a phonograph. Fig. 2 is a front elevation of the repeating device, parts being broken away to more clearly illustrate the construction. Fig. 3 is a detail perspective view of one end of theattachment looking from the rear. Fig. 4 is a transverse sectional view of the repeating attachment on the line 4 4 of Fig. 2.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The sound-reproducing machine shown in the drawing is of the Edison 'or other type and includes the usual sound-box A and soundbox carriage, having a forwardly-extending arm B, which under normal condi tions is supported on a stationary guide-rail at the front of the machine.

. The attachment which forms the subject of the present invention includes in its construction a substantially U-shaped frame 10, the vertical arms of which are widely separated, and the base member of this frame is held in position by a suitable clip 11, confined by thumb-screws 12, that ass through slotted openings in the clip in order to permit ready readjustment of the frame both toward and from the phonograph and in the direc-, tion of its length.

the frame are openings for the reception of pivotins that project from arms 15 and 16, w 'ch latter are connected by an intethe forwardly-extending arm B of t e soundbox carriage.

At-the r ght-hand end of the framethat is to say, adjacent to the vertical'bar 18 .,thereof-the bar 17 is provided with a slightly-angularupper edge 20, as shown in Fig. 4, for en agement by a locking-lug 21, that projects om a pivotally-mounted' arm 22, this arm 22 being pivoted between two ears ofa stud or bracket 24, that is carried by the base, and being normally held to the left, or'in the osition shown in Fig. 2, by means of a sma l compression-spring 25.

the arm B of the sound-box carriage is al'-- lowed to travel in a horizontal plane, which with the recor such record, the carriage being moved to the right, as usual, and on arrivlng at the end of the record the arm B will engage the arm 22' and move the lug 21 from bar. 20, ermit ting the latter to rise in the manner ereinarm B, moving the sound-box carriage up out of re roducm position.

In or er to e ect the necessary adjust-' points in the length of the cylinder, the upper end of the arm 22 is provided with an opening for the passa roughly adjusted an then ocked 'in lace by a set-screw 28. The inner end o this "pin is threaded and carries a nut 29, which may be turned inorder to effect the very 111- this the lowermost position of the bar 20- permits the re roducing-stylus to engage" and effect reproduction of after described and to elevate with it the ment for records that terminate at different.

At the upper ends of the vertical arms of gral bar 17, that forms a rest or support for i too eofa in27,whichis movesthearm 22 to release os1t1on.

' riage will I nut42- to be engaged by the arm B when the inclined face of the bar.

fine adjustment essential to stop the movement of the carriage at the end of the reproduction.

The left-hand arm of theframe is provided with a lug 31, arranged for the reception of a curved arm 32, having at one end a hook for the reception of the end of a carriage-returning sprmg 33, which moves the carriage back to starting position after the bar 17 has been elevated, and in order to At a point near the arm 30 is a stud or bracket 37, to which is pivoted an arm 38, thatis bent upward to. the rear of the bar 17 and is provided with an openin for the re ception of a pin 40, which may e locked; in

place by a set-screw 41, and this 'pin, has a.

threaded innerend on which is mounted a carriage'reaches e initial or'starting osition. The arm 38 is bifurcated, so as to ibrm an auxiliary arm 45, that extends rearward of the arm 30' of the frame. and is ro.vided withtwo stops 46 and 47', arrange respectively, to engage against the outer and the inner faces ot the arm 30 and limit move.- ment of the arm 38. This auxiliary arm 45 is rounded: and forms a cam, for en a ement with the lower-faceof the arm-16 o t ecarriage-suplporting bar 17, and when said arm 38 is pu ed to theiritght by an adjustable s ring 49, extending etween the arm and the standard 50, the cam will elevate the arm 16 and the bar 17, this operation occurimmediately after the carriage-arm B At the right-hand end o the frame is a s ring 51, one end of which is connected to tlie arm, 18 and the other end to. the arm 15 .of, bar 20, this spring 51 being much weaker than the spring 49- and'serving to draw the bar-20'down to the lowest positionafterthe arm 38. has been moved outward by engagement of" the sound-reproducing carria e therewith, and in this. connection it is to e noted that the downward movement of the bar 17 under the influence of thespring 51 'is limited by a stop 54, that projects from the auxiliary cam-arm 45. In the operation of the device the bar 17 will be normally held in its lowest position bythe engagement of" the lug 21 with the As the soundbox carriage moves to the rightlduring the reproduoin operation the arm of the oarfinally engage with the nut 29 of pin 27, moving the arm 22 to the right and releasing the lug 21. As soon as this occurs the heavy spring 49, acting on the arm 38, causes the auxiliary cam-arm 45 to act on to the inoperative osition. occurs the s ring-.ock 34 moves under the lower edge 0 the bar 17 and looks the latter the arm 16 and elevate the bar 17 to such an extent as to raise the sound-box carriage As soon as this in elevated position, so as to support the weight of the sound-box carriage during=its return to initial position under the'retractile force of the spring 33L When the arm B ofthe sound-box carriage engages the nut 42 of pin 40, it will move the arm 38 to the'left, and said arm will engage the arm of spring 34, moving the latter to release position, and at the same time the cam-arm 45 will be carried to the leit, moving mitting. the spring 51 to drawthe bar 17 down to the initial position. As soon as this is accomplished the. stylus of the sound-box engages the record at the starting-point, and

,at the same time the arm 22moves to the left and its lug 21 engages over the bar 17 holding the latter down until the completion of the reproducing operation, after which the same operation is repeated as many times as necessary or until the motive power is exhausted.
