REPRODUCING PIANO.

Application filed July 1,

To all whom t may concer/ri:

Be itknown that I, FRANCIS LiLNooLN YOUNG, a citizen of the United States, and

resident oi' New York, in the county of Neiv York and State of New York, have invented certain new and useful Improvements in Reproducing Pianos, of which the following is a specification.

My present invention relates to improvements in reproducing pianos and more particularly to improved means for adapting the instrument to play interchangeably with various makes of music-sheets having diiferent kinds and arrangements of yexpression 5 controlling perforations.

The drawings illustrate one of the preferred embodiments my invention is adapted to take. In them, Fig. 1 is a vertical vsection partly in elevation through the 20 tracker mechanism, etc., within my invention, said figure also showing in vertical section the cut-oil valve boxes used in connection with the foregoing, and further showing diagrammatically the more important 1" operative parts of a reproducing piano including a diagrammatic showing of the pneumatic connections between the related parts of all of the foregoing; Fig. 2 is a face View of the main and supplemental trackers of Fig. 1,-in other words, a view of same as looked at from the left hand side of said Fig. 1, .the middle portion of the main tracker bar being broken away to save room in the drawing; and F ig, 3 is a top lan view of part of the devices shown in 4iig. 1 including the main and supplemental trackers and related parts and one oitl the cut-ofi' valve boxes, only one of the supplemental trackers being shown as aforesaid in top plan view, the other, namely supplemental tracker 11, being shown in horizontal section taken through its row ot expression controlling ducts in Fig. 1.

Describing now my invention as illus- "i trated by the particular embodiment thereof in the drawings, 1 is the main tracker bar with its note-playing ducts 2. Projecting longitudinally from each end of said main tracker bar are integral spaced apart exten- 'W sions 3 and l connected at their ends by the transverse piece 5.

On the back of each-piece 5 is secured a bracket 6, therebeing aligned bearings in said brackets which yreceive the ends of a 1922. sei-iai No. 572,225.

rock shaft 7 located behind the tracker bar.

Mounted on and rrigidly secured to this rock shaft are the brackets. 8 .and 9, the forward ends of which respectively'support the supplemental tracker sectionsl() and .11 within the rectangular'openings 12 atthe ends of the main tracker bar 1, the said rock shaft permitting said supplemental sections 10 and 11 to be adjusted transversely relatively to the tracker v1 to bring at will any of the rows 14, 15 or 16 of expression ducts in said supplemental sections into proper playing position relatively to the note-ducts of the tracker 1.

The tracker 1 and the sections 10 and l1 are all transversely crowned on their active or music-sheet contacting face (compare Fig. 1), the crowning being on substantially the arc of a circle described about the longitudinal axis of the rock shaft 7 so that the music-sheet will make proper contact with the ducts of the main tracker and of the supplemental sections in spite of transverse adjustments given to the latter. Fig. 1 shows a music-sheet 21 in playing position on the tracker, the part 21a of said sheet being supposed to be on a music-spool, and the part-21b being supposed to be wound on the usual take-up spool.

Row 15 is shown in proper playing position. The other rows 14 and 16 are supposed to be out of play, row 14 being one notch above playing position and row 16 being one notch below playing position. The notches referred to are the notches 17 formed in the side of one of the end pieces 5, best shown in Fig. 2. These are severally adapted to be releasably engaged by rib 18 on the back of a leail spring member 19 located4 in a space provided for the purpose between the piece 5 and the adjacent supplemental tracker section 11, the inner end oi" said member 19 being fixed to the bracket 9 (F ig. 3), and its outer end being provided with an operating knob 20. Thus, means is provided constituting a handle for the operator to use in simultaneously adjusting the sections 10 and 11 to bringthe desired row of expression controlling ducts into play and to lock same in position against unintentional displacement.

The broken row of ducts 14 shown in the drawings correspond and are adapted to play with expression perforations of the socalled Duo Art music-rolls, The other rows 15 and 16 may be assumed to correspond and be adapted to play the expression perforations of two other kinds or makes oi reproducing piano music-rolls, so that the aforesaid tracker bar construction is capable oi playing said three different kinds of reproducing piano music-rolls.

Whichever of the rows of expression ducts 14, 15 or 16 is selected to be operative, the other rows are automatically rendered inoperative so that the ducts of said latter rows will not be aifected by the passage of music-sheet perforations over them. The means Jfor accomplishing this will nov: be described, that shown being one convenient form of said means. Y

Qi, 25 and 26 are cut-ofil valve boxest one tor each row et' expression ducts 14, 15 and 16. Fig. 1 shows these bol-ies in vertical cross section, and Figu 3 shows part ot one of them, namely, pai-t ot bor; 25, in plan view. All oi the box-es are of the same construction so that the description ot one sufices for all.

Each box contains as many enclosed circular chambers 2l' as there are expression ducts in the row 14, 15 or 16 to which the given box relates. 4F01 instance7 boi: 25 will lhave nine of such chambers 2T (only three, however, beingl shown in Fig. 3 Jfor the sake oi' simplicity) severally connected to the nine ducts ci the row 15 by tubes 28.

Every chamber 2T is divided into an upper and l wer part by a diaphragm or pouch 1ilvery tube QS connects with a duct Q9 which opens into the 1upper pouch chamber. headingl from every upper chamber is another duct 30, Then the pouch 13 is up3 t is adapted to close the mouths of said ducts 29 and 30.

31 is a duct which connects with all ot the lower pouch chambers in the given cutoff box.

Q40, 250 and Q60 are three ports on the tace ot the block 32 being the mouths of three duct-s in said block whose other ends are severally tube-connected, as best shown in 1, to the ducts 31 oic the hoz-:es @el and Q6 respectively.

fla is a rearward extension Afiom the bracket 9, said extension carrying` the port 9b being` one end ot an elbow tube 9c whose other end is connected by a tube S3 to the suction or exhaust d evice said port il being adapted to be caried by said extension 9a into communication with one at a time ot the ports 24th 25() and 260. the others remaining open to the atmospl ere.

lt will be understood that the ducts 29 and and the tubes 28 are kept .normally on suction by reason ot their connection with the exhanster through interveningl pneumatic connections in the saine manner that the tracker tubes connected with the note-playing ducts of the tracker bar of the ordinary piaycr piano are kept` normally on suction.

imrtli x, it will he undcrstoml that whenever there sucion in the lower pouch chambers, the pneumatic p1 .ie on both sides oi" the pouches is e. ..lzed and the ponches drop and do no. cnt of communication between the ducts Qi) and S6. This is the condition which happens to he shown in lief; Q5 (Figi. 1l diie to the esiliati pori, 9b being in communication with the port 2543 which in turn is connected. as prevonslj,7 dei-:cribedv` with all ot the lower pouch. ch: bers in the box This res "s in the ducts Q9 and 30 in said bei; l5 being pnt into ccizimunication without any ohstrurtion by the pouches 13,---which in tuV results in malting operative the related row 1a ot expression controllino' ducts.

Sin'iilarly, the row 1l or the row 16 oi' expression controllingl ducts is brought into proper playing; iosition relatively to the note ducts in the main tracker, lthe mere act ot makinr this adinstn'ientwill rendering said row ot ducts l! tive to function with the expre ations ot the given music-sheet .incense said adjustment will bring the walnut.,-A pfurt 9b into conm'iunication resp-tc! velt' with the port 240 or the port Q60, and will ielease the pouches ot the box 2J; or the bora 2J respectively, depending upon which row ot ducts 14 or 16 has been adjusted into playing position.

Vice versa. the rows ot expression controllingl ducts which are not in playing` position arey thereinv antoniatirallv iendcred inoperative. This is the case with rows i-l and 16 in Fin: i. and results troni the tact, that the ports 2l!) and tf) are open to the atmosphere and, therefore. all oi! the ponche; 13 in the related cut-eti hoi-es Q-land :26 are pressed against the months ot thi` ducts Si) and 30 and have cut otiA conmninication between said ducts and theieiore have rendered inoperative said related rows lland 16 of expression controlling ducts.

Referring' now to the rest ot the apparatus shown in Fig. 1, yet to he described. l's may take so many 'forms that l have shown them only diagrannnaticaliv. Thus. il?, represents any usual pneumati'.: action tor actuating` the hammer mechanism ot' the piano.

,The exhauster 34 is operativelyy connected to the pneumatic action through the expression box 35 as shown.

"37 is any well known Aform of valve box Moperatively connecting the cut-out boxes 24, f a 25'and 26 with theexpression box 36 and vwith soft and sustaining pedal operating means 41 and 42, etc., usual to these instruments. Although there are three of these 1 cut-out boxes, there need be only one valve box 37,`because, as already explained, only one oi said cut-out boxes is operative at one 4time to operativclyconnect the given active 'ii one duct 30 of box 26, all three of said ducts 30 being then operatively connected by tube 39 with one of the valve mechanisms 37 in the valve box 37. .s

In'the same way', other duct-s 30 respectively from the boxes 24, 25 and 26, will or may be inter-connected in sets of three, and in turn connected tothe respective valve mechanisms in box 37 adjacent said valve mechanism 37,

Although I have shown and described the rows 14, 15 and 16 of expression controlling ducts as operating through one and the same expression box 36, it will be obvious that I could make them operate through three different kinds or constructions of expression boxes, the latter method having the advantage that expression boxes could be chosen respectively adapted to render with thefbest possible effect the expression perforations of the different kinds of musicrolls, but said duplication of expression boxes will, of course, have the disadvantage of adding that much more mechanism to the piano with corresponding increase in its cost and its complication. Also, there may be a special valve box 37 for each expression box 36.

It is possible that other changes and modifications may be made in the illustrative embodiment of my improvements which will, nevertheless, still be within the scope and spirit of my invention and within the scope and spirit of the annexed claims, and as such are intended to be covered thereby; also that certain features may be used without others.

I have happened to illustrate an embodiment of my invention adapted to play threel kinds of music-rolls but, of course, the invention is adapted to be embodied to playy two or any greater number of kinds of rolls by correspondingly reducing or increasing the number of rows of expression control-` ling ducts and the cut-off boxes and connections, etc.

What I claim is:

1. Means ttor adapting a reproducing piano to play interchangeably with musicsheets 'having different kinds and arrangements ot expression controlling perforations, said means comprising a main tracker bar having note playing ducts; a supplemental section having plural rows of expression controlling ducts, the said rows being respectively adapted to co-act with the expression controlling pertorations of said different. kinds of music-sheets; said supplemental section being supported for transverse adjustment at the end of the main tracker bar to permit any of its rows of expression ducts to be brought into proper playing position relatively to the note ducts in. the main tracker bar.

2. Means for adapting a reproducing kpiano to play interchangeably with musicsheets having different kinds and arrangements of'expression controlling perforations, said means comprising a main tracker bar having note playingy ducts; a supplemental section having plural rows of expression controlling ducts, the said rows being respectively adapted to co-act with the expression controlling 'pertorations of said diferent kinds of music-sheets; said supplemental section being supported for transverse adjustment at the end of the main tracker bar to permit any of its rows of expression ducts to be brought into proper playing position relatively to the note ducts in the main tracker bar; and means which automatically renders inoperative all expression ducts except the particular row which has been brought into said proper playing position.

3. Means for adapting` a reproducing piano to play interchangeably with musicsheets having diiierent kinds and arrangements ot expression controlling perforations, said means comprising a main tracker bar having note playing ducts; a supplemental section having plural rows of expression controlling chiots; the said rows being respectively adapted to co-act with the expression controlling perforations of said different kinds of music-sheets; said supplemental section being supported for transverse adjustment at the end of the main tracker bar to permit any of its rows of expression ducts to be brought into proper playing position relatively to the note ducts in the main tracker bar, there being one of said adjustable supplemental sections at each end of the main tracker, said sections being structurally united so that the transrerse adjustment of the one section carries with it. the other.
