To aZZ whom t may concern.'

Be it known that ALBERT KALINOSKY, a citizen of Poland, residing at New York, county of New York and State of New ork, have invented certain new and useful improvements in Phonograph Repeaters, of which the following is a specification.

My invention relates to improvements in the repeating mechanism of phonographs, and it is the principal object of my invention to provide a mechanical repeating mechanism which is automatic in its operation, and which may conveniently be installed into any existing type of musical instruments of this class.

Another object of my invention is the provision of a repeating mechanism allowingl an adjustment to cause the operation of the repeating mechanism to suit theV exact size of each record to be reproduced.

A further object of my invention is the provision of a repeating mechanism provid ing for the raising of the reproducer needle from the record groove prior to the return of the reproducer to starting position.

AV still further object of my invention is the provision of a repeating mechanism including means for regulating the gradual introduction of the needle into the record groove at the completion of the return movement in order to avoid injury tothe record.

Other objects of my invention arethe provisions of means for adjusting the repeating mechanism to suit the width of the inner circle or to the size of the groove nest, and of means for throwing the repeating mechanism out of action if this should be desired. Y

Still further objects of my invention are the provision of means for coupling the repeating mechanism with the motor and uncoupling it therefrom at given times, and of means for ensuring this action at the proper times.

According to my invention the record itself is used for returning the repeating mechanism into its working position after each operation. r

The invention shall now be described in its preferred form with reference to an embodiment thereof in a machine using disk records, and which is provided with the usual articulated reproducer arm.

Referring morespecifically to the drawings, 10 indicates the ordinary box or housing of the phonographprovided with a cover 11 hingedly oonnectedin theV ordinary manner, 12 the turn table and 13 a disk record.

The` usual amplifier and bracket 14 support the'V articulated reproducer arm 15 pivotally attached by means of pin 16 to one arm of a bracket 17, secured with its other arm to the upper part of the box 19.

The free end of the tone-arm 15 is shaped to forni a drinn 18 open at the ends and the front. In this drum the roof bar of a hollow T-piece 19 is rotatably arranged, the outer ends of which carry handles 20 and 21 while its inner wall are connected by nieans of pins 22 and 23. The tubular shaft of the T-piece is open at its end and adapted to receive a knee piece 24 to which the sound box 25 carrying the stylus 26 is removably attached in the usual well known inanncr.

To pin 23 is attached a longitudinal rod 27 near its inner end, while the end of said rod loosely engages the other pin 22. A wire loop 28 is attached with one of its ends to the inner wall of the tone` arni and rests with its looped other end 29 on rod 27, to the free end of which a chain 3() is attached at one end, the other end of which is secured to one end of curved bar 3l attached with its opposite end to a pin 32 rotatably secured in the walls of bracket 14 extending through these walls and carrying at one end a curved finger The end of arin 15 has at its lower end a transverse partition wall 34 to which a pin 35 is attached, adapted to enter into an opening in a partition 36 arranged within bracket 14.

In the outer wall of arin 15, at sonic distance above its lower end two screws 37 and 38 are secured, and a curved plate 39 provided with longitudinal slots 40, 41 slides across the outer wall of the tone arin andis guided by the shafts of screws 37 and 38 playing in slots 40 and 41. At one end the plate 39 carries two outstanding checks 42 and 43 4) and the lower flattened end of an angular lever 44 is engaged between both cheeks, while its upper end is guided through a bracket 45 and shaped into a handle 46 by ineans of which plate 39 can be displaced across the tone arm.

Plate 39 is fornied in approximately its center with an angular nose or projection 47 having' a toothed or stepped outer end 48, and to the projection 47 is pivotally secured by a pin 49 with a binding eect the split rear end of a finger 56, to the upper front edge of which one end of a` leaf spring 51 is attached as at 52, the other end of which is curved upwardly and then downwardly te pass through a slot in finger into engagenient with the steps or teeth 48. The side wall of finger 50 is cut to forni a curved groove 53, and the other end of finger 50 is forked to form two prongs 54 and 55, and a hook 56 is attached to the side face of finger 50 opposite the groove 53.

A shaft 57 journaled in the vbox 10 is adapted to receive its rotation by ineans of pulley 58 from the pulley 60 on a shaft 61 rotated by the niotor of the phonograph in the usual inanner. This shaft carries a collar 62 at its inner end which is hollow to receive the end 63 of a connecting ineinber 64 having a collar 65 at one end and a collar 66 at its opposite end which is also hollow for the reception of the end of a worin shaft 67 keyed to member 64 as at 68. The ineni` ber 64 and the end of shaft 57 are provided with a longitudinally extending channel 69, in which a latch 7 0 is longitudinally displaceable provided with a recess 71 in its upper face, the end of which latch is engaged by a spring 72 normally tending to press the latch into its locking position.

A coupling elenient or leaf spring 73 is fastened at its rear end to a block in boi: 10 as at 74, while its other end is forined into a lug 75 having an upstanding lip 7 6 at one side. The lug 75 is split as at 77 in its lower face and cut away as at 78, and the material of lug and lip 76 is set o so as to forni a channel 79 of a curvature best illustrated in Figure 8.

Collars 65 and 66 are channeled to guide a pin or rod 80, the outer end of which is formed into an open loop, and 'the inner pointed end of which engages in the channel of lug 75 to raise the saine whilegliding along the upper curved wall of the channel 79 to raise the lower, downwardly curved lip 81 out of recess 71 of latch 70 to allow a shooting home of latch 76 under the action of spring 72 to couple shaft 57 with ineinber 64 to which the worin shaft 67 is keyed (see Fig. 14).

A hair spring 82 is attached at one end to collar 66 and its opposite end is wound around the shorter shank of pin 86, and this spring has the tendency to return pin 8O after each operation into its original position as will be hereafter more fully described.

Collar 66 carries an Sshaped pin 83 for a purpose later to be referred to, and worin shaft 67 carries at its opposite end a collar 84 provided with an upstanding ridge A tubular sleeve 86 has forn'ied therewith a cam 87 and is keyed as at 88 to a stub shaft 89 which is also keyed at 90 to worin shaft 67, and the other end of which is journaled in a suitable bearing 91 in bonY 16.

The cam 87 is excentrically mounted on shaft 89 and has a shape best illustrated in Figure 5, in which the upper end of the cani is formed into a curved thumb piece 92 separated from the cani by a recess 93, and linger 33 engages Cain 87 as shown in Figure 5.

A block 94 having a longitudinal slot 95 and a graduation 96 is secured to the top plate 97 of the phonograph box 10 which is also slotted in alignment with slot 95 to allow the passage of a vertical pin 98 provided at its upper end with a handle 99 by means of which pin 98 may be displaced in slot 95. This pin is also passed through a. horizontal bar 100 carrying at its other end an operating knob 101. The lower end of pin 98 is secured to a horizontal bar 102 having an angular arm 103 extending across worm shaft 67 a'bove the same, and ending into an angular linger 104. Bar 100 is displaceable in a depression of cover or topplate 97, and a cover plate 106 set into plate 97 flush'with its upper face, covers the repeating mechanism, and is provided with guides on its upper face in which a segmental slide 107 is displaceable to allow an inspection of they mechanism through a slot in p-late 106 covered by said slide 107.

Means are provided for shifting block latch 70 to disconnect the worm shaft 67 from the shaft 57 ,by means of lug 75 which is formed on one end of leaf spring 73, the under side of said lug 75 having a cam 78 as is shown clearly inrFigs. 9 and 10; and said leaf spring is so mounted at 74 to create a pressure between the underside of cam face 78 and upper face key 7 0, thereby keeping under side of cam face 78 in contact with upper face of key 70 when worm shaft 67 and shaft 57 are connected; and as'the two rotate together with key 70, which has a recess 71, one sideV of said recess 71 having a beveled side 70a (see Fig. 15) comes inrcontact with cam face 78 hereby allowing the narrow portion 7 6a, of cam face 78 to gradually drop into recess 71 and disengage key 70 from shaft 57.

As will be apparent from the following description of the operation, the projection 104 at the end of the arm 103 is, in the revolution of the worm shaft 67, engaged by the ridge and moved upwardly to llift the arm 103. This arm in its upward movemen engages beneath hook 56 of finger 50, to lift the finger and disengage the same from the worm shaft to interrupt the swinging movement of the tone arm. Therefore, the position of the arm 103 determines the point at which the swinging movement of the tone arm is arrested, and as this arm 103 can be moved to different positions by shifting the bar 102 by means of the handle 99, it is obvious that `the outward movement cf the tone arm can be interrupted at any desired position, that is,'in`accordance with the initial or starting groove of the record. By this construction, the tone arm can be placed in proper starting position for records of different sizes through the adjustment of the bar 102 as described. l

The repeating mechanism operates in the following manner:

After adjustingv slide loop 102, 103, 104 by the proper manipulation of knob 101 or handle 99 to suit the size of the record to be played, and shifting finger 50 by the proper manipulation of handle 46 according to the size of the inner circle ofthe record', so that it will engage needle 80 at the proper moment, i. e. at the end of therecord, the motor is started. The engagement of the needle 26 with the record 13 will swing the arm'15 in the 'usual manner to turn'in bracket 14, until, at a predetermined point i. e. at the end of the record, the prongs 54 and 55 of finger 50 will have engaged needle 80 and press the. same inwardly until' its pointed end gliding along the inner upper curved wall of 'slot 79 will lift leaf spring 73 to allow latch 7 Oto be shotV home under the action of its spring 72 to couple shaft 57 with the worm shaft 7 At this moment, when worm shaft 67 starts to'rotate, the S-shaped pin 83 on collar '66 will engage and ride upwardly in groove 53 of the finger 50 along the bottom'wall thereof and bring the same into engagement with the worm shaft. At this moment the finger 33 will travel towards the highest point of the cam 87 and during this motion finger 33 will be swung backward to draw the inner end ofV curved bar 31 forward and lower its rear end, tauteningchain 30 and pulling on lever 27 to rotate the T-piece 19 within drum 18 and raise its outer end to which the sound box is attached so that the same is lifted off the record. The rotation of worm shaft 67 with which finger 50 is worm shaft 67 will be in a position which allows linger 33 to drop into the lowest part, so that bar 31 is raised again to slacken chain 30 and to allow the needle 26 to drop into engagement with the record and to repeat the above described cycle of movements.
