To all whom it may concern:

Be it known that'I, WILLARD S. PAIN, a citizen of the United States, and a resident of Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in -Perforated Music-Sheets and Tracker-Boards of which the following is a specification.

This invention relates to improvements in music.sheets and tracker boards to be used in connection therewith and relates particularly to that class of music sheets and instruments therefor which are provided with accenting devices and with supplementary ducts in the tracker board for leading to neumatic means for operating the accenting devices. Heretofore accenting holes have been provided along the edge of the sheet so 'as to register with special ducts at the ends of the row of ordinary ducts in the tracker board, but due to the shrinkage of the paperand other irregularities it frequently occurs that these accent holes do not properly register with the special ductsin the tracker board and it also occurs that when the bearings for the rolls are shifted laterally so that the ordinary music note slots register properly with their ducts, the accent apertures are thrown out of register with the supplemental ducts.

The object of my invention is to avoid these ditiiculties in a simple and effective manner.

In the accompanying drawings in which like letters of reference indicate like parts in all the figures :-Figure 1 is a face view of my improved music sheet, parts being broken away and others omitted. Fig. 2 is a vertical longitudinal sectional view of the tracker board, parts being broken away.

The note sheet 1 is provided with the usual note slots 2 arranged according to the melody and which are .to register with the corresponding ducts 3 in the tracker board t. At each end. the tracker board is pro vided with a supplemental duct 5 which is considerably wider at its mouth than the ordinary ducts I have shown such a duct 5 at each end of the tracker board as the tracker board shown is to be used in an instrument which has the mechanism divided into two parts, one for the bass and one for the treble. Of course if the instrument does not have such division itwill not be necessary to have two ducts 5 and a single v rnnromrnn music srrnnr 'aitn rairoxnii noann."

Specification of I duct will suffice. vided along its edges with accent apertures 6 which are made small and always appear in multiple, that is in groups of at least two, but both apertures 6 of one group are on the same transverse line of the sheet and are to register with one and the same duct- Of'course it will be understood that when there is only one duct 5 in the tracker apertures 6 need be arranged only along one edge of the sheet but when there is a duct 5 at each end of the tracker board the apertures 6 must be arranged along both edges of the sheet. If the sheet is dis olaced transversely to its length and longitu inal to the tracker board, as frequently occurs in playing this displacement does not necessarily interfere with the tracking of the note slots 2 with their ducts 3 because even if these note slots only partially track with the ducts 3 the playing pneumatics will still respond. But such displaoement'is sufficient to bring the small accent apertures 6 out of tracking position with the ducts 5 and for this reason these small apertures 6 are made in multiple as I have shown, and I prefer to make them in duplicate as a greater number might weaken the note sheet too much at the edges. These note sheets are not ubject to any great stress nor are they act to be injured any where except at the edges which must retain to as great an extent as possible,-the inherent stiffness of the paper, as otherwise they are apt to be turned or folded over thus preventing proper tracking. It is therefore not permissible. in View of the nature of the paper to weaken the edge parts to any great extent andaccent openings of the size of'the smallest punch for a note slot wpuld make holes so large that the edge of the paper would be weakened. to such an extent that it would not only be apt to be doubled over but would be torn. Extended testsof my improved note sheets as described above have shown that the multiple small openings in transverse rows in the sheet do not weaken the edge of the sheet and do not cause the same to be turned or doubled over.

Having described my invention what I claim as new and desire to secure by Letters Patent is The combination with a tracker board, for pneumatic key instrument player, which tracker board has a supplemental duct in addition to the usual note ducts, the dimen- The note sheet 1 is prosions of the mouth of which, in the direction siderably less than the correspondin .di-
