JOSE SAMPERE, 0F J OSE SAMPERE,

NEW YORK, N. Y.; MARIE SAMPERE, ADMINISTRATRIX 0F SAID DECEASED, ASSIGNOR T0 .WIN TER & CO., A CORPORATION OF NEW SHEET-ADJUSTING APBARATUS.

To al? iii/mm, 'it may cm1/cern vBe it known that I, JosE SAMPERE, a cit-izeii of the United States, residing in the borough of Manhattan, in the county of New 1 ork and btate of New l ork, have invented Specification of Letters Patent. Application filed March 2, 1911.

certain new and useful Improvements in Sheet-Adjusting Apparatus, of which the following is a. specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in sheet adjusting apparatus and has particular reference to and is illustrated in the accompanying drawings in its piano player.

.Referring to the accompanying drawings, Figure 1 is a front elevation partly in sec` tion of an apparatus illustrating an applicalion of my invention. Fig. 2 is a planv view looking downwardly upon the same.

Fig.3'

application to a is an enlarged view of the tracker board, and;

valve mechanism partly in section on the line -wi of Fig. 4, looking from the back of the saine, and Fig. 4 is a view looking from left to, right at F ig. 3.

5 is the outer framework in which t-he usual spools 6 and 7 are suitably mounted and upon .which the tracker board S is secured. One of these spools may be driven iii any'suitable manner as by the chain 9 engaging the. sprocket provided with pinion 11 engaging the gear 5() of the spool. which the other end of the other shaft 60 10 secured to the lshaft 11 13 is another bracket in.

may be mounted and from which it is forced;

righiwardly by the coil spring 14, said bearing being retained within the bracket 13 bv .any suitable means such as the collar 15 held by the pin 16. .At the opposite extremity of the shaft GO is mounted an arm 17. The other end of this arm or bracket is suitably secured to theA shaft 19 which is preferably beiitqt right angles at the opposite extremity serving as a bearing 20 for the cam 21 mounted within the bracket 22, secured to the frame 5. rfhis cam is secured to the lever 23 by the pin 24 so. that as the lever 23 is moved, the cam 21 is moved within the bracket. 22 thereby causing the shaft 19 to shift the spool 6 rightwardly or leftwardly. The lever 23 is pivoted to the lever 25 which is pivoted to the'pneumaticprovided with chambers 2,642.7 connected by the bar 28. 29 and 30 are tubes communicating respec- PatentedJaii. 27, 1914. seriai No. 611,896.

tively with each of the chambers 26 and 27 of said pneumatic and the slide pieces 31 and 32 of the valve mechanism. These slide pieces are provided with the movable menibers 33 and 34 which are L shaped as sho-wn to better advantage in Fig. 4 and project above the surface of the tracker to engage the edges of the perforated sheet 35. These movable members are preferably pivoted to the slide pieces as shown at 36 and 37 and are provided with projections 38 and 39 adapted to cover the openings 404-41 in the tubes 29 and 30 respectively.

42 and 43 are screws or other suitable means serving to guide the slides 31 and 32 Arespectively provided with the slots 44 and 45. These guides are preferably tapped or threaded to receive the bar 46 which is also tapped or threaded as shown, the threads running in opposite directions and may be provided with a linger piece 47 which may be knurled and secured to said shaft so that upon turning said finger piece, the slides come together or separate as may be required to adjust the movable members 33 and 34 to various widths of perforated sheet music. The tracker board may be cut away as shown at 4S to accommodate the finger piece 47 to allow the bar 46 to lay closely to the side ofthe tracker board and to keep the same in position, and the projections or arms 3S and 39 may be provided with suitable packing such as leather 49 or the like upon the inner surface where the saine closes the openings of the tubes 29 and 30.

From the foregoing it will be understood that when the sheet of music shifts to one 'side it shifts one of the movable members 33 or 34 thereby opening one of the ports 40 or 41 to the atmosphere and allows air to pass through one of the tubes 29 or 30 to one of the chambers 26 or 27 of the pneumatic. As soon as the air is allowed to enter one side of the pneumatic, that side immediately expands and shifts the lever or bar 25 as aforesaid thereby causing the spool 6 to move rightwardly or leftwardly so as to keep the perforations of the sheetin alineinent with the perforations in the tracker board.

Of course it will be readily understood that various modifications may be made without departing from the spirit of the invention as set forth in the claims.
