MUSIC-SHEET.
To all whom tit may concern: pneumatics for sounding a set of speaking devices 55 Be it known that I Wrrr.YAM H. Ross a citizen of which may be regarded as the normal or lower manual. the United States residing at Worcester county of In addition to the note channels the tracker-board is
Worcester and State of Massachusetts have invented 6- a new and useful Music-Sheet of which the following is a specification.
This invention relates to an improved construction of music sheet for use on automatically controlled musical instruments having two sets of speaking devices such
10 for example as a double'manual organ one set of speaking devices of which corresponds with one key-board or. manual while the other set of speaking devices correspondswith the other key-board or manual such as is described and claimed in my application for patent
15 Serial No. 289 077 fled November 25 1905 on an."Automstic musical instrument" of which this application is a division:
The especial object of this invention is to provide a music sheet particularly adapted for use with instru-
20 menta of the general character mentioned above so as to enable such an instrument to produce automatically all variations and combinations which can be made in playing such an instrument by hand.
Reference is to be had to the accompanying sheet of 25 drawings which represents one form in which my in-' vention may be embodied and in which
Figure 1 is a plan of a tracker-board such as may be used on instruments of the above mentioned character and Fig. 2 is a plan partly broken away of a music sheet
80 embodying the present invention.
In playing a double manual organ by hand it is possible to secure a wide range of effects; for example a melody may be played on the upper manual and the accompaniment on the lower manual; or a melody may
85 be played on the lower manual and the accompaniment played on the upper manual. By means of couplers the melody may be sounded upon both manuals and the accompaniment upon either one of the manuals alone; or the melody may be sounded upon either of
40 the manuals while by the couplers the accompaniment may be sounded on both sets of manuals. Where louder effects are desired the melody and accompaniment may both be sounded upon both manuals. In addition to these ordinary variations a skilled organist
45 will also produce more complicated effects such for ex-ample as may be done by "trilling" a note from the upper to the lower manual or by other rapid changes from one manual to the other.
The especial object of the present invention is to pro-
50 vide 'a music sheet especially adapted for use in'bhe
above mentioned ways and for producing any or all of
the effects set forth. To accomplish these results in an
automatic musical instrument the tracker-board T is
provided with a supplemental set of channels N' which operate an individual set of switches one of these switches corresponding to each note channel and serv- 60 ing to change the sounding of the note from a speaking device corresponding to the lower or normal manual to a speaking device of the upper or supplemental manual.
The individual switches are of a delicate quickly responsive construction; permitting instantaneous 65 changes from one mamigleee the other for "trilling' or rapidly shading effects. The tracker-board is also preferably provided with a main switch channel S corresponding to a single line of perforations of a music sheet for controlling a main switch for causing all notes to he 70 sounded upon the upper or supplemental manual with-out the use of the individual switches and the tracker-board additionally is preferably provided with a single channel J corresponding with a single line of perforations on the music sheet for actuating a coupler device 75 not shbwn for causing notes to be sounded in unison upon both manuals.
Each of the channels N of the tracker-board which corresponds to a note is connected by suitable means
in such a manner as to exhaust the pressure from a 80 channel leading from one of the speaking devices of a set of such speaking devices corresponding to the lower manual and it is also so connected as to bring into action one of the speaking devices of a set of speaking de-vices corresponding to the upper manual. These con- 85 nections are of ordinary construction except as is indi- sated in the above mentioned application. When operated in this way the same note will be sounded in unison upon speaking devices in each set of said speak-
ing devices. 90
The exhaustion of pressure to permit an automatic coupling action is preferably controlled from the marginal tracker-board channel J. This tracker-board channel registers with a single margiral line of perforations of the music sheet and is connected with a coup- 95 ling device as is set forth in the above mentioned application in such a manner as to permit the simultaneous sounding of a note on both manuals for various lengths of time even down to the very shortest grace notes which could possibly be desired. 105
As has been stated corresponding with the note channels N of the tracker-board the latter is also preferably provided with a supplemental set of perforations N' one of which corresponds with each note perforation these supplemental channels preferably alternat- 105 ing with the note channels. Each of these supple-mental or individual switch channels is connected to
provided with a set of note channels N which control operate a check valve as inset forth in the above men-
the required perforations are located.
Having thus fully described this inventie. nd ascertained the manner in which the same is to be per-
formed; what I claim `as new and desire to secure by Letters-Patent is+-
1. As an article of manufacture a music skeet having two sets of note perforations located in interspersed rows
one set representing a distinct musical part and the other
along one edge with a line of perforations 1110 for Oper= the acconrnaniment therefor 'said sheet having a marginal 25 ating the coupler mechanism to sound all notes in uni- row of perforations at the side of the note perforations

10 this purpose the tracker-board is provided with the marginal channel S above mentioned corresponding with a single line of perforations` near the edge of the
music sheet. This channel is connected by suitable perforations and in which the main switch and coupler connections with a series of check-valves each corre- are controlled by the marginal perforations respectively

I regard this as desirable because by controlling the main switch from a single line of perforations of the music sheet it is possible to avoid multiple cuttings in the music sheet which otherwise might be necessary if a general switching action was produced by the control of the switches individually. It is to be understood also that the particular design of music sheet in which the switch perforations are alternated with the note

be sounded on the upper manual. Also a wide variety
30 of elaborate effects may besecured-by combinations of the music sheet perforationsreontrolling the individual switch mechanism and the.note perforations. For example the set of mijsic sheet perforations A—A' will produce. "trilling" on two notes` of. the-upper
35 manual; the set of perforations B will produce a single_ note on the upper manual; the set of perforations C will sound a .note first on the lower manual and then switch the latter part of the note to the upper. manual;
'the set of perforations D will produce a "trill" in meat with certain note :perforations corresponding to the
40 which the same note is sounded alternately upon the lower manual whereby said sheet may be used on a double
