Y. Cranford, county of U nien-, a

To aZZ whom it may/c c W'HEINS a citija resident of nd State of New is a specification.

My invent nrelates to mechanical musical tomechanical players for Struments and to the perfoets used in connection therewhen the music-sheet is in or out of exact almement with' the tracker ducts and for readily readjusting it to proper alineinent.

In the drawmgs,`Figure` 1 representsv in front v elevation so much of a mechanical Inusical instrument or mechamcalmstrumentplayeras isnecessary to show the invention. ig. 2 is a transverse vertical section through vtho 151132 2 of F 1 lool-ing to tho loft. 'o

2 esignates a take-upv roll rotated by a shaft 21, which is turned by suitable and well-known means.- (Not shown.) A

3 designates a music-roll which carries the ordinary music-'sheet 31, provided with the usual note-perforations 32 for cooperating ducing devices. In addition to the perforations 32 the sheet 31 is provided -with an lthe ordinary means (not s own) for rotating Specification of Letters Patent. ipiiottio mea 'Juno 24,1905. serai No. 266,732.

which may detachably engage with the shaft It will beseen that the operator by turning f tho key o3, in-oahor dirootion-moy, through the'worm'O and lug 57, turn the rockshaft 53,"which in turn acts through the lugs 55,

engaginglin the grooves 51 of the collars 5, to adjust t e'shafts 21 .and 34 simultaneously "and equally in either direction longitudinally of the tracker-board 1, or, in other words, laterally of the path of motion of the music sheet 31,y which travels over the tracker. It will b e observed that this lateral movement of the sheet may be produced at any time, whether or not the sheet is in operation. v

kFig.1 shows the indicator-arm' 7, which forms an important feature of the invention;

It is shown as ivotall mounted on the tracker 1 althoug it is o vious that it might be mounted on any other convenient part of the instrument which is in fixed relation to the tracker-board. When in its operative position, its: ointed end 71 exactly corresponds with t e uide-line 30 yon the sheet 31, providin that t e-sheet is in roper adjustment wit the tracker, in whic case the perevice the driving-shafts 21 and 34 artition-walls 43 and' 4 4. vOnj each of the s afts 21 and 34 is mounted a col- I' *the shaft whenitis -desired to rewind the IOO i" yfruffltted guide-line will accurately overl theimperforate space betweenthe tvvn series of ducts 11 in the tracker. By means of this indicator the operator is enabled to immediately note lthe slightest variation ofthe mu sic-sheet fromjits A true lateral'position with- `relation to the tracker and by means of the,

ke 63 to instantly correct the same. v

t is of course understood that'while the instrument is being played the indicator' 7-is stationary, so that its point'71 always occupies the same position relative to the tracker For convenience,`however, the indicator may be-pivoted, asm Fig'. 1, so that 'it can be swung up' away from' the sheet for convenience in placing' the music-roll 3 in position 'orinremodving theV same from the instru` ment.

It is ofcourse obvious'that other vdevices than' that shownmay be used'to secure the relative movement of the music-sheet lor its supportingsrolls and the tracker-board to.

provide'the required lateral adjustment.
