Description

has been connected with the Winding-roll 3. and the apparatus put in motion, it is evi-' dent that the sheet will be drawn over the tracker 2 to effect the playing of the instrumeat. It will be seen that the edge of the sheet passes between the :hilurcate sides of the block 43. it will also be seen that the pneumatic 23 tends by its expansion to force the music-sheet 8 to the left of-the'drawing Fig. l, which tendency is opposed by H e light spring 23*. if at any time the slr. eet 8 should be forced too much to tl e left, its edge will bear against the block 43, so as to turn the lever 40 on its pivot 41 and raise the valve 37 from its seat 36. Air under pres- Inatic to iexh aust to atmosphere. "sprang 23* then acts to draw the music-sheet sure from the chamber 1 will then pass through thevalve-ch amber 35 and tube 34 to raise the-diaphragm 33 and move the valve 32 from the position shown in Fig. l of the drawings, so as to connect the tube 30 with the pressure-chamber 31. This in turn depresses the diaphragm 29 and acts, through the lever 28 to raise the valve 26. Tl. is cuts oil" connection between the pressure chamher 25 and pneumatic 23 and pernuts tle pneu- Tl e 8 to the sight of the drawing Fig. :1. It is understood that in practice these lateral movements of the music-sheet 8 are very slight and are repeated as often as is necessary to insure movement-of a music-sh set in its'true pathouer the tracker 2. lnordinary cases the alternate expansions and contractions of the pneumatic 23 will be very slight, amounting to a more wavering of the finger 22 suilicient, however, to hold the musicsheet 8 in its correct alineinentthat is, in correct transverse relation to its path or" movement.

It is obvious that very many mechanical changes may be made in the form of my in vention without departing from its spirit. It is also clear that While I have shown the instrument as actuated by pressure above that of atmosphere, it would require only such knowledge as is possessed by any one skilled in the art to make the necesssary mechanical. changes for adapting it to an instrument operated by suction.

W hat I claim isl. A music-sheet-guiding device comprising means normally operative to move the including a part bearin senses a sheet laterally in one-direction, and means v against an edge of the sheet and movable laterally thereby for governing said sheetsrnoving means.

2. A musicsheet-guididevice comprising pneumatically actuate means 'fo1"n1ov 'ing the sheet laterally, a movable part against which the sheet bears when laterally deflected from its path, and connections between said movable part and said moving means for controlling the latter said connections including a pnesrnatic valve moved by said part.

' 3. A music-sheetguiding device comprising means normally operative to move the sheet laterally in one dniection, a movable part a ainstlwhich the sheet hears when.

moved by said means from its :path, and connections between said movable part and said sheet-moving means for controlling the latter.

4. A music slieet-guiding device comprising means including an actuating-pneumatic and suitable connections for moving the sheet j laterally, and means including :a, movable part against which the sheet bears when de-' ilected from its path and a valve connected to said movable past, and pneumatic-connections between said valve and said actuatingpneumatic'for governing the latter.

5. A enusic-sheet-guiding device comprisi a tracker, longitudinally movable musicro' l-supporrting shafts at each side of said tracker, pneumatically actuated means for longitudinally moving said shafts simultaneously and equally, a partbearing ainst an edge off the music-sheet and movab e late erally thereby, and a pneumatic valve moved by said part for governing said shaft-moving means.
