' To Yall whom t may conc-ern.'

Be it known that I, EDWIN M. KnLLoGG,

vcitizen of the United States, residing at Mo Iinefin the county of Rock Island and State of illinois, have invented a certain new and useful Improvement in Repeating Mechanism for Phonographs, of which the following is a full, clear, concise, and exact descri tion.

'lv y invention relates to phonographs and has for its object the provisionv of improved mechanism whereby the phonographs may automatically repeat the playing of records. In accordance with one feature of the in'- vention the mechanism that is adapted to effect the return of the tone arm structure to normal position is so located with reference to the record supporting turn table as not to require displacement in order to permit the removal and replacement of records.

The invention has for another object the provision of improved mechanism operated by the turn table actuating mechanism and controlled by the tone arm structure to effect movement of the latter torecord starting position upon the completion of eachv performance and while this second object of my invention is desirably accomplished by mechanism which permits the removal and replacement of records without requiring readjustment of the parts, yet this feature of the invention is notte be so limited. The invention has for its further object the provision of improved means whereby the number of times a performance is to bey repeated is limited, this means being desirshowing the preferred embodiment thereof and in which Fig. 1 is a plan view of a part of a phonograph with parts removed to reveal details of construction and other parts broken away which are not essential to an understanding of the invention; Fig. 2 is a sectional view on line 2-2 of Fig. 1; Fig,

-3 is a side view of the structure shown in Fig. 1; Fig. 4 is a perspective view of novel features of the invention; Fig. 5 is a view on line 5-5 of Fig. 2 and Fig Gis a view on line 6--6 of Fig. l.

table l `for supporting a disc record, a record 2 being indicated. The turn table has a hub portion 3v secured thereto. A spindle 4, ro-

tated by a lspring' or other suitable form of motor; passes through the hub of the turn table and a distance: beyond the turn table, each .record havingv a central aperture 5 in which the upper end of the spindle ma be diiving connection with the hub by any suitable means such as the pin and slot structure 6, Fig. 2. The parts of the phonograph thus far specifically described in connection with the accompanying drawings are wellfknown to those skilled in the art as isalso the form of tone arm structure illustrated and which is inclusive of the arm 7 mounted to swing at its o'uter end upon the mounting 8, the inner end of the arm having a section 9 swingingly supported upon the balance of the arm and carrying or terminating in a sound box 10 that has a stylus carrier .11 for holding a stylus 12 receivable in the spiral record groove upon the record disc.

The type of phonograph illustrated is well known to those skilled in the art but the 1nvention is not to be limited in its applica.

tion thereto.

In practicing my invention I employ a track 13 which extends across a portion of the turn table 1 toward the central portion thereof, the track being interposedv between the turn table and the' tone arm structure that overlies the turn table. The track 1s hinged at its outer end upon the support 14 mounted upon the top portion 15 of the phonograph cabinet and is normally positioned to be out of effective engagement with the tone arm structure. The track may be lifted at its inner end to be inclined outwardly, as indicated by a dot and dash line in Fig. 2, to lift and be engaged by the tone arm structure on the outward movement of the latter, said vtone arm structure be.- ing desirabl provided with a bearing roller 16 engagea le with the track and allowing the tone arm structure to roll downwardly on the track with minimum friction.

The track is desirably positioned as indicated in Fig. 1, occupying an arc of the circle traversed by the roller 16, in the bodily movementY of the latter. vI preferably emplo a spur pinion 17 below the turn table andy ri 'dly secured upon the hub of the turn ta le in order that the spindle' may at y' all times be free for the reception and the removal of records which may readily be inserted within the space intervenin between the track 13 and the turn table an removed from such space. A spur gear wheel 18, also below the turntable, is mounted to turn upon an upright stub shaft 19 which may be secured to the cabinet portion l5 `by means of the pointed end of the shaft 19 driven into said cabinet portion. Some of the teeth of the gear wheel are omitted as indicated in Fig. 1 to permit the gear wheel and pinion to be normally disengaged. A cam 20, of any shape suitable to its function and also preferably located below7 the turn table, is arranged to be operated by the gear wheel 18. This f cam is preferably circular and concentric with the gear wheel 18 with which it may be integrally formed. The track' 13 has a continuation 21 engageable with the cam. The continuation 21 of the track normally rests upon the lowest portion of the cam whereby the track is normally maintained in its lowermost positionout of effec- Y 25 tive engagement with the tone arm structure. A" in 22 projects laterally from and turns wit the spindle, this pin being preferably directly secured to the hub of the spur pinion 17. Anotherpin 23 is movable radially of the gear wheel 18, to be engaged with and separated from the ypin 22, being slidably mounted at its inner end within the hub of said gear wheel and at its outer end within the high part of the. cam 21, the pin 23 thus this pin inwardly turning withv the gear wheel18. A spring 24 surrounds the pin 23 and has its inner endA `in engagement withI the hub of the gear wheel 18, the outer end of said spring ena-ging the abutment 25 fixed uponsaid pin. aid spring'thus serves to press the pin 23 outwardly. A pin depressor 26 is mounted upon the cabinet portion 15 and normallyv engages the outer end of the pin 23 to press normally to preserve it out of engagement with the pin 22.

f I employ mechanism, operated by the tone arm structure when reaching its inner recordv finishing position, for breaking the normal engagement between the pin die-f pressor 2,6 and the pin 23. The mechanism illustrated for this urpose is inclusive of an arm` pivoted at 27) upon the cabinet portion 15 and preferably made up of normall relatively

fixed sections

28 and 29 whic are frictionally coupled at 30. Said arm is adapted to be brought into turning en gagement with the gear wheel 18 when the tone arm'structure reaches its inner record finishin position. To this end the tone arm is provi ed with a depending pin 31 engageab e with the arm section 29 to move the arm 28-29 against the pin 32 upon Vthe gear wheel 18. As a result of the engagement of the arm 28j-29 with the pin 32, the gear wheel 18 is turned in a counter-clockwise of engagement with the pin idepressor 26 whereupon the spring 24 projects the pin 23 into the circle of travel of the pin'22. As the pinion 17 turns the pin 22 thereon will engage the pin 23 and continue .the rotation of the gear wheel 18 to bring the teeth thereon into engagement with the teeth of the pinion 17 The gear wheel 18 will thereupon be turned one complete revolution to bring the gear wheel 18 to the normal position illustrated in Fig. 1, the teeth of the pinion' 17 escaping the gear wheel 18 vjust as this gear wheel is placedin the normal position -shown. The cam`v 2O accompanies the gear wheel I18 in its rdtation and causes the track structure to Aproceed through its cycle of movements. clockwise 'direction the extension 21 of the track 13 is gradually raised to bring the track into engagement with the roller 16 upon the tone arm structure which has now reached its inner record iinishing position. While the track continuation 21 rests upon the high part of the cam the track 13 will remain in its outwardly inclined position sufiiciently long to allow the tone arm structure to be brought to its outer position. When the tone arm is in yits outer position the high part of the cam-will leave the track continuation 21 which thereupon de.- scends upon the cam to the inclined position illust-rated in Fig. 2, whereby the track 13 is gradually lowered to bring the stylus 12 into engagement with the record at the initial end of the latter.

The track structure desirably carries a cushion-abutment 33 engaged by the sound box to limit ,the outward movement of the tone arm structure. This abutment is adjustable along the track to suit the record which is being played. The timeiat which the pin 31 is to engage the arrn section 29 may be adjusted with reference to the length of the record by turning this arm section 29 s the cam rotates in a counter' upon its companion 28, the frictional engagement between lthe two arm sections beingfsufficient to maintain them in rigid relation after the desired adjustment has been sein the form of a depending rim. The second member 38 of the brake, is arranged'to engage with the braking rim 37 when the turn table 1s`to stopped. The brake member 38 38 and which are successively engaged by the outer end of the in 23 in ea'ch bodily revolution thereof. ach vtime the record is played the wheel 39 is turned a step tobring the brake member -38 a step nearer its engagement with the brake' member 37. The

number of times that the record lis to be played is determined by the number of pins 40 which are successively engaged by the pin 23. The number of times that the record may be played may be adjustably determined by initially setting the brake member 38 which'may be done by manually adjusting the disc 39. In this adjustment theI number of pins which the pin 23 may successively engage before the brake member 38 engages the brake member 37 is arbitrarily determined. ;It is possible so to adjust the disc 39 that only one'pin 40 will be'encountered by the pin 23 before the brake member 38 engages the brake member 37, in which event the record will be played only once. j If the diskv39 be adjusted to permit two p-ins 40 to be successively engaged by the pin 23 before the brake member 38 engages the brake meml ber 37 the record will be played twice, and

so on. For convenience of the user, the. periphery of the disc 39 is knurled and has thereon a number of indicating marks 41 disposed around its periphery and numbered in correspondence with the number of times therecords are to be played, there being an index plate 42 having a mark43 thereon with which the selected mark 41 is broughtlnto register in determining the adjustment of the brake member 38.

While I have herein 'shown and particularly described the preferred embodiment of the invention I do not wish to be limited to the precise details of construction shown as changes may readilyl be made without departing from the s irit of my invention, but
