To all whomttm/ayl concern:

Beit known that I, HENRY PRICE BALL, a 1 citiZenofthe United States, residing at New York city, county and State ofNew York, have inventedcertain new and useful llmrovementsI i'n Music-Rolls for Mechanical usical Instruments, of which the following is a specificationf.

, My inventin consists in the construction lo lof a music roll and its'supports, 'as also in the means whereby the muslc strip upon'the music roll isv centered relative tothe trackerboard.

The object of my invention i's to provide a Amusic roll on which a music strip may freely .expand and contract when influenced by atmos heric conditions, and which will serve to gui e the music strip and cause it to register with the desired openings inpthetracker' '2o board, and thus overcome the objection-oi` z 5 ments employing a music strip and a tracker- 3 5 Fig. 2 is a view 1n perspective'of the music roll 'and the devices forexerting an inward pressure upon the guiding iianges and giving Fig. 3 is a longitudinall motion to the roll. section through the tubeformin partof the 4o music roll. Fig. 4 is a longitu inal section through the tube, and vertical section through the guiding flanges at the ends of the tube.

Fig. 5 isa longitudinal section and elevation' of a modified form. offroll, its supportin mechanism and centering mechanism, an

'also showing in elevation and section a music strip partially wound upon the 'music rolll Fig. 6 is a perspective view of the nip le used to transmit motion of the power sha t tothe 5o music roll.

In the drawings, 10 indicates the supporting body Jr'vor the music strip.v ,This may be constructed as shown in Figs. 1, 3 and/1, of a hollow tube, formed of any'materialwhch v will have substantially the same coefcient of expansion' and contraction, under atmospheric conditions, as the substance of which the music stri is made. now comm'o y formed of pa er,.I may 'form this tube of paper; that is, I) may form the tube of a er pulp or by su er'posing layers of Etliie re uired width I wish it understood that-I do not limitLmyself-inanywise to the manner of making the- -tube, or of the material from which it 'may be 'As music .strips are .upon each other until the desire diameter of tube is obtained.

made, so long as it will contract and ex and in accordance with the contraction an expansion of the `music stri wound thereon.'

,Insteadlof-primarily orming the tube as vshown'in Figs. 1, 3 and 4, I may form the supporting body by winding a/portion of the material from which the music strip is made upon a separate body, as shown inFig'. 5i In this figure, strips or' other forms of metal, or

' other material, 1 1 are connected together by 'means of rivets 12, and upon such body there is wound the required number of layers of thel music strip 13. It will be observed from a comparison' of Figs. 1, 3, 4 and5, that'ineach form of music roll provision is made for 'the admission .of atmospheric air to the interior of the supporting body.-` Tl1is I find to' be necessary owing to the fact that if air is only allowed access to the 'outside of the supporting body, it iwill not contract and expand at the same ratio as that ofthe music strip Wound on it, but at ja different ratio. In

other words', to produce the best results, the' supporting body must be so constructed that the air wi ll act equally on all sides.

The supporting'body 10 is made preferably 'I slightly longer thanv the' width-of themusic strip: f Arranged ateach end of the 'supporting body are the guiding flanges 14, vhaving openings 15. To carry the supporting body y and ilanges 14v in a mechanica musical instrument, withwhich it is to be used, and to 18, vand ends turned oppositely at right angles 19. These nipples have their cylindrical portions 17 introduced into thesupportingv provi de means for transmitting motion to the l music roll, there is arranged in each end of the supporting body the ni ples 16, Fig. 6,. i These nipples consist 'of a cy mdrical portionv i 17, having the projecting parallel extensions Amusic strip 13 ex ands.

The music rol, so far as described', to-

' gether with the music strip wound thereon,

forms what may be termed a commercial music roll, such as is now sold for use with mechanical, musical instruments.

In order to provide for moving the guiding -flanges inward upon contraction of the music .strip ilipon'the music roll, I provide th'e disks 20. iese disks are mounted on and secured l' to short shafts21, 22, carried in bearings 23,

on the mechanical musical instrument and in which they are 'longitudinally movable. These shafts extend through the disks and are ada ted to be introducedinto the open ings 24 etween 4the parallel extensions 18 of thev nipples 16, thereby supporting the roll. In order to give motion to the roll, the disks 20-are slotted across their inner faces, 25, to receive the ends'lQ of the nipples 16. The slots 25 are made of such depth that when the disks 20 are moved inwardly the flanges 14 will be brought in contact with the outer ends of the sup orting body 10, beforethe ends of the nipp es 16 seat themselves in the bottom of the slots. Motion is transmitted to the music roll by means of the broad faced gear 26, in mesh with a narrowfaced gear 27, on`shaft 22. i l In order to center the music roll'relative to the trackenboard, as well as to provide for the inward movement of the disks 20, there is mounted upon the shafts 21, 22, the collars 2S. These collars are slotted and located in the slots are pins 29, mounted in yokes 30, on the Aupper end of levers 31,- ivoted at 32. Connected to the lower end o `the levers 31, are the. links 33, pivoted to a lever 34, which is pivoted at to the frame of the instrument and centrally of the tracker-board.

' In order t`o exert a constant elastic tension in an outward direction upon the links 33,

the spring36, is employed. The lever 34 is" also provided with a handle 37, by means of which the position of the links 33 and the disks 2O maybe regulated by hand.

The operation of the device is as follows Then changes in atmospheric conditions takeplace, the supporting body will expand and contract vwith the music strip mounted on it. There expansion takes place, guiding flanges 14 are moved outwardly.. When contraction takes place, the guiding flanges`14 under the action of the s ring 36, acting through the links 83 and dis s 20, are moved inward. Centering of the roll :.is `eil`ected,

owing to the fact that the disks ..14 make `equal pressure on opposite 'ends of the roll.

The centering device and means for moving the disks 20 inwardly I find to be well adapted for the purpose. I wish it understood, however, that I do not limit myself to the employment of the mechanism described, as it is obvious that very many devices may be employed which will accomplish the same result. L
