Original application flled lvovember 4; 19d? Serial'No. 400,681; Divided and this application flied December I I I 17,1908. Serial N0. 4G8,OH87.'

To all whom it may concern:

. Be it known that I,- Anrnonsn LAURnxr. Musrnn, a citizen of the Re ublic otF ance, rance,' have in vented certain new and useful ovements in' AutomaticPlayer-Pianos and the Like, of which the following is a full, clear,

and 'exact description.

Thepresent application is a divisional of tracker for instruments of the type-mentimed-{and it is particularly intended -for gstrgments havingmore than a :single key j object of my invention is toprovide a suitable tracker for thisjpurpose, which 'is of the 'iusual width and preserves the customaryfa mm. interval between adjacent tracker 2holes,'while at the same time. ar-

ranging-,the holes'for the differentseries of keyboards, one behind the other in the line 4. travel of the usual perforated band, whereby i the necessity for excessive delicacy in. the adjustment and positioning of thefl It is a further object of my invention to.

' "so. construct the tracker that it may be employed with hands perforated in the usual way for either of the instruments embodied in my combination instrument, .while at the same time being adapted'ior service with bands perforated so as to operate the combined instrumentsat the same time.

Two embodiments of the n-inciple of the tracker with. superposed holes'and the arrangement of the'perforations in the band of paper employed with this tracker are illustrated in the accompanying drawing. e

In this (ha-wing Figilre's 1 and 2 are diagrammatic front elevations of two forms of the tracker; and l!" 3 illustrates diagrammatically an examp ed the bandjof perforatod paper unwound in. 'front of. :the

tracker. Fig. 4 is a diagrammatic-sectional elevation showing the pneumatic, its 'valve mechanism and the connection to theper foratio'ns in the tracker in the form shown in Fig. 1; and Fig.5 is a similar View of he mechanism as arranged for a tracker in form shown in F ig.-2.

It will of course be readily understood that the same notes of the piano and organ maybe simultaneously sounded by arrangin that a erforation b shall. lie over the Fig. 1) or'bf (Fig. 2) atthe same time that a perforation a lies over the hole'a. And it is furthermore obvious that a band of pei-fo'ated paper provided with perforations for one of the two instruments only would. actuatevthis instrument asif it were isolated without actuating the other.

Modifications in this structure which do not depart froininy invention may be devised and I do notliniit myself-to the prebut claim as my invention: p 1. A tracker ,bar havinga plurality of sets of apertures .in its working face alined transversely of tie tracker, independent sets of pneuinatlcs communicat ng therewith respectively, each set of apertures occupying a -ilitt'oi-ent extent transversely of'the bar, substantially as described. T I

2. A tracker bar having a plurality of sets of passages corresponding sets of sound operating p'neuinaties 'connnunicating there- I with respectively, correspondingsets, of apertures in the wo'rkingface of said tracker opening into said )assages, said apertures being alined in the cirection of the travel of thermusic sheet ti'ansveiselyof said bar and occupying a different extenttransversely of the bar, substantially as and' for the purpose.

described.

.3. A trackerbar having a plurality of sets of apertures in its working face alined transversely of the tracker, independent sets of p'neumatics communicating therewith respectively, each setof apertures occupying a different extent transverselyof the bar, in

combination with a music sheet provided with a plurality of sets of perforations of different length,.the perforations of one set serving to o'peratively open but a,single set of apertures in the tracker,substantially as described. l i

4.- A trackerbar having a plurality o f sets of apertures in its' working face alined transversely of the tracker and communicating with independent -sets of pneumatics,

each set ofaperturesoccupying a different extent transversely of the bar, in combination with a music sheet provided with a plurality of sets of perforations of different lengtlnlthe perforations of eachset serving to operatively open a; different set of apertures in the tracker, substantially as described.

5. A tracker provided in its working face with a plurality of sets of apertures opening to independent sets of pncuina'tics for operatin different sound rodiicin instruments. g b 3 One setof apertures. extending a greater distance t 'ansvei s'ely of the tracker thanthe I other, in combination with a perforated music sheet provided withtwo sets of perforations,'one coniprisin separate perforations of constant area am the other comprising p'erfo'ations ofless width an'dgreater length, each Set serving to a but a single set of apertures. p

A tracker provided in its working face with two parallel-sets ofapertures alined transversely of the t 'ackcr and communicating with-independent sets of pneuinatics for operating difierent ound producing instru merits, in combination with a perforated inusic sheet provided with two sets of per-- fdrations, one comprising separate perforations ofc'onstant l pcratively open A nnuisionsand the other comprisingperforations of loss width and of greater length, each set of perforations scrving to operatively open but a single set of apertures. sulistantia ly as described.
