EUGENE T. TURNEY, OF ROCK IFSLAND, ILLINOIS, ASSIGNOR TO ARTISTA PIANO PLAYER COMPANY, OF MILAN, ILLINOIS, A CORPORATION OF ILLINOIS.

WINDING AND REWINDING MECHANISM FOR MUSIC SHEETS OR RECORDS.

To all whom it may concern Be it known that I, EUGENE T. TURNEY, a citizen of the United States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in l/Vinding and Rewinding Mechanism for Music Sheets or Records, of which the following is a specification.

This invention relates to improvements in winding and rewinding mechanism for perforated musical sheets or records for use with pneumatic playing attachments for music instruments, and the primary object of the invention is to provide improved means for adjusting the record or music sheet with respect to the tracker board over which it is adapted to pass, to properly position the same to aline the apertures therein with the apertures in the tracker board.

A further object is to provide improved means for adjusting the record rolls to position the music sheet or record with respect to the tracker board while the record is passing over the tracker board and without stopping the operation of the mechanism.

A further object is to provide an improved form of roller adapted to center the music sheet or record and prevent it from piling up at the end of the roller as the roller shifts.

A further object is to provide an improved device of this character which will be simple, durableand cheap in construction and effective and efficient in operation.

To the attainment of these ends and the accomplishment of othernew and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings, illustrating an embodiment of the invention, and in which,

Fig. 5 is an enlarged detail sectional view on line 55 of Fig. 7 Fig. 6 is a detail elevation of the sleeve for holding one of the locking members of one of the record rollers against displacement. Fig. 7 is an enlarged detail sectional view partly in elevation of the locking mechanism for locking one of the rollers to the op eration mechanism. Fig. 8 is a view of the I elastic band or collar which holds the bearing sleeve in place.

Referring more particularly to the drawings and in the present exemplification of the invention a suitable frame comprising side members 10 and a top and bottom member 11, 12 is provided, which frame is supported in any suitable manner within the casing of the instrument and in any desired position convenient for the operator. ithin the frame thus formed is an upright member 13 which is spaced a short distance from one of the end members 10, preferably the right hand end, and secured between the member 13 and the left hand member 10 is a tracker board 141, which is preferably located midway of the top and bottom members 11, 12. This tracker board 1 1 is provided with the usual apertures 15 and connected with the respective apertures are flexible tubular members 16 which are also connected to the pneumatics which operate the piano action and which are not shown in on from the roller 18, it will be centered with respect to the roller and prevented from piling'up at the ends of the roller as the latter is bodily shifted in a manner to be set forth. axles or trunnions which are loosely ournaled in suitable bearings 21, one of which is supported by the end member 10 and the The roller 19 is provided with other by the member 13 and these trunnions or axles 20 are of a length to extend for a short distance beyond the respective bearings whereby the roller 19 may be shifted longitudinally in its bearings to vary the position of the roller with respect to the tracker board 14. 22 projects through one extremity of the trunnion 2O beyond the end member 10 of the frame to prevent the trunnion from being displaced with respect to its bearing.

Secured to the free extremity of the other trunnion 20, beyond the member 13, is a gear wheel 23 which may be held in position in any desired or suitable manner, preferably by means of a fastening screw or bolt 24 passing through a collar 25 on the gear 23 and engaging the axle or trunnion 20. This gear 23 is adapted to mesh with an elongated pinion 26, which is secured to the extremity of a flexible rotary shaft 27, which latter passes through a suitable aperture 28 in the adjacent 'end member 10 of the frame so that when the shaft 27 is rotated a rotary motion will be imparted to the receiving spool or roller 19 to wind the record sheet 17 thereon as it is paid out from the roller 18. The aperture 28 in the member 10 is adapted to permit the shaft 27 to be flexed by means of a suitable op erating rod 29 connected to the collar 30 which surrounds the shaft 17 to move the pinion 26 out of engagement with the gear wheel 23.

. The roller 18 is provided with a trunnion 31 projecting from one extremity thereof, which is journaled in an adjustable bearing 32, which latter is supported by the end member 10 and is adapted to move longitudinally in a suitable bushing 33. Secured to the outer face of the member 10 is an elastic member 34 preferably in the form of a leaf spring, one extremity of which engages the outer extremity of the bearing 32. Projecting from the opposite extremity of the roller 18 is a trunnion 35 which is provided with the ordinary laterally projecting lugs 36 adapted to project through suitable slots 37 in a bearing 38 when the extremity of the trunnion 35 is seated in the hearing so that the rotation of the roller will impart a rotary motion to the bearing 38. The hearing 38 is provided with a projecting shank or trunnion 39 extending from the opposite face and at the diametric center thereof and this shank or trunnion projects into a sleeve 40 which latter is provided with a bifurcated portion 41 and a circumferential groove or recess 42 adjacent one extremity thereof, preferably the extremity in proximity to the bearing 38. Secured to the opposite extremity of the sleeve 40 is a disk 43 which is of a'diameter somewhat larger than the diameter of the sleeve.

A sleeve or bushing 44 is provided 111 the A suitable cotter or pin upright member 13 and preferably projects for some distancebeyond the face of the member remote from the roller 18 and is of an internal diameter slightly larger than the external diameter of the sleeve 40, so that latter may be inserted within the bushing to rotate freely when the roller 18 is rotated. The sleeve 40 is held against displacement with respect to the bushing 44 by means of the disk 43 which stands adjacent one extremity of the bushing and a spring clip or collar 45 which is adapted to be seated within the circumferential groove 42 in the sleeve 40 beyond the other end of the bushing. A pin or lug 46 projects laterally from the shank or trunnion 39 and extends into the bifurcation 41 of the sleeve and is preferably of a length that the extremity thereof will stand flush with the periphery of the sleeve. This pin 46 is adapted to move longitudinally in the bifurcation 41 and when the bearing 38 is rotated, it will engage the side of the bifurcation to rotate the sleeve 40 within the bushing 44 and also the disk 43. The bifurcation 41 in the sleeve preferably has its opening adjacent the bearing 38 and the elastic band or collar 45 which holds the sleeve 40 against displacement with relation to the bushing 44 is adapted to project across the bifurcation to prevent accidental displacement of the shank or trunnion 39.

When it is desired to remove the bearing 38 and the shank 39, the elastic band or collar 45 is first removed and then the shank 39 may be easily drawn out of the sleeve and if desired, the sleeve 40 may be also drawn out of the bushing in the opposite direction.

Supported by the disk 43 and preferably secured to the face thereof adjacent the member 13 is an elastic member preferably in the shape of a flat spring 46*, one extremity of which is secured as at 47 to the face of the disk 43 and the other extremity 48 rests upon the head 49 of a pin or projection 50 which extends through the disk and beyond the opposite face therof.

A bodily movable member 51 is located between the member 13 and the adjacent end member 10 of the frame. This member 51 is supportedby means of the flexible shaft 27 which passes loosely therethrough adjacent one of its extremities, as at 52, and the member is of a length to terminate short of the bottom member 12 of the frame. The upper extremity 53 is provided with an inclined slot 54 into which a lug or projection 55, supported preferably by the member 11 of the frame, extends. The slot 54 is inclined toward the member 13 so that when the member 51 is bodily depressed by means of the shaft 27 when the latter is flexed under the influence of the operating member 29, it will also move in a direction toward the member 13. Supported by this member thereon.

' 51 adjacent the disk 43 is a stub axle 56 upon whichis journaled a sleeve 57 and supported by the sleeve is a disk 58 which is of a diameter substantially equallto the diameter of the disk 43 and is provided with an open slot 59 in theperiphery thereof. The sleeve 57 is held against longitudinal displacement with respect to the stub axle 56 preferably by means of a screw or bolt 60 which passes through the sleeve and into a peripheral groove 61 in the stub axle 56. The sleeve 57 18 of such a length that the disk 58 will normally stand in close proximity to the disk 43 so that when the member 51 is bodily moved, the disk 58 will be brought into close proximity with the disk 43 to permit the lug or pin 50 to enter the slot 59 and lock the.

tension of the elastic member 16* until the slot is brought into alinement with the end of the pin or lug, at which time the latter will spring into the slot to lock the parts.

Any suitable means may be provided for rotating the disk 58 from the shaft 27. A suitable and eflicient means for accomplishing this urpose comprises a sprocket wheel 62 supported by the sleeve 57, and a similar sprocket wheel 63 supported by the shaft 27, and a sprocket chainfit surroundlng the two sprockets 62and 63.

in Fig. 1 of the drawings, the pinion 26 will be in engagement with the gear wheel 23 and motion will be imparted to the roller 19 to wind the record 17 thereon from the roller 18. Then it is desired to re-wind the record upon the roller 18, the shaft 27 is locked and also to disengage the pinion 26 y from the gear 23. The disk 58 being rotated by the shaft 27, it will be apparent that when the disks are locked together, the roller 18 will be rotated in the opposite direction and the record will be re-wound Any suitable means may be provided for shifting the record 17 longitudinally with respect to the tracker board 1 1 in order to properly aline the apertures in the record with respect to the apertures in the tracker board and for this purpose there may be provided a pin or member 65 which is loosely supported preferably by the upright member 13. This pin or member 65 is of a length somewhat greater than the thickness of the member so as to project for some distance beyond the faces thereof, one extremity being adapted to engage one face of a peripheral flange 66 on the bearing 38 and if desired, a suitable piece of fabric 67, such as felt or the like, may be secured to the member 65 to act as a brake on the spool 18. Pivotally supported intermediate its ends on the opposite face of the member 13 is an arm or lever 68. The free extremity 69 thereof stands in close proximity to the extremity .70 of the pin or member 65 and is adapted to engage said extremity when the arm or lever is rocked so as to bodily shift the roller 18 longitudinally so as to move the bearing 32 in the bushing 33 against the tension of the elastic member 34 to slide the record 17 longitudinally over the tracker board to the desired position. When this roller 18 is thus bodily adjusted, the roller 19 will be automatically adjusted longitudinally by means of the record 17, the trunnions 20 of the roller 19 being adapted to move freely in a longitudinal direct-ion in the bearings 21. During this bodily movement the gear 23 will move longitudinally along the elongated pinion 26 to prevent accidental disengagement of the operating mechanism. The roller 19, being crowned, will cause the record to be uniformly distributed or centered thereon and will prevent the record from piling up at the ends of the roller.

Any suitable means may be provided for rocking the arm or lever 68 aboutits point v of pivotal support 71. A suitable and effi- VVhen the parts are in the pos1t1on shown cient means for accomplishing this purpose w1ll now be described.

An ad usting bolt or screw 72 1s rotatart d, preferably by means of the upright member 13. One extremity of this bolt or screw 72 is provided with an operating head 73 located to one side of the member 13 preferably adjacent the roller 19. The other extremity 73 of the screw or bolt projects for some distance beyond the opposite face of the member 13 and the bolt or screw is held from longitudinal displace ment preferably by means of a collar or bushing 7 5 which surrounds the bolt or screw 74 adjacent the member 13 and is secured to the-bolt or screw by means of a suitable fastening pin or member 76 passing through the collar and engaging the bolt. This collar cooperates with a shoulder 77 formed by the operating head 73 of the bolt acent the opposite face of the member 13. Mounted to travel upon the threaded extremity 7 1 of the bolt or member 72 is a nut 78 which is provided with a convexed surface 79 adjacent the arm or lever 68, and projecting beyond this convexed surface is a lug or pin 80 which preferably extends parallel with the extremity of the bolt or member 72 and projects into a bifurcation 81 formed in the free extremity of the arm or lever '68. With=thisconstruetion it will apparent that when the'head '73 -is operated to rotate the shank of "the bolt ormember 72, the nut 78 will-be fed toward-=or away from the member 13 according to-the direc tion of rotation of the operating head 73.: -VV'hen the nut '78 is'fed away from the mem-, ber 13, the bifurcated extremity'of the-lever. 68 will also be moved away from the mem ber 13 when thenut 78 engages and moves sai'd' extremity and "when the nut -7 8 is 1 fed toward the member 1 3 the extremity "69 of the 'lever'will be moved in'a direction away from the roller 18- to release the tension on. the elastic member 34 which latter will shove "or move the roller 18 longitudinally in its bearings toadju'st the record 17 with re; spect tothe tracker board. The convexed surface 7 9 of the nut 78 permits the lever 68 to be freely rockedand the pin or proj'ection' 8O which extends into the bifurca tion 81 will hold the' nut 78 against rota-r tion with the bolt 'or "member 7 2.
