Specification of Letters Patent. Patented Aug, 30, 1910,

Application filed June 16, 1906, Serial No. 322,014. Renewed February 7, 1910. Serial No. 542,646.

To all whom. it may concern: Be it known that I,'FRANCIs L. YOUNG,

a citizen of the United States, and a resi-' 'provide for the automatic selection of the notes to be accented, which automatic'selectlon 1s controlled by manual means, so that it may be rendered operative for different ranges of notes or inoperative at the will of the operator.

Still further objects of invention will appear in the specification and be pointed out in the claims. I H .In the drawings, Figure 1 is a front elevation of so much ofa m'echan'ical musical instrument as is necessary to show my invention, the casing and other parts of the instrument being removed. Figs. 2, 3, 4, 5 and 6 are vertical sections through the planes 2- 2, 33, 44, 5 5 and (36, respectively, of Fig. 1. Fig. 7 is a longitudinal vertical section through the plane 77, Fig. 3. Fig. 8 is a vertical section through the line 6-6 extended downwardly through the action casing. Fig. 9 is a diagrammatic view of the note selecting connections.

In the drawings, 10 designates the tracker of the mechanical musical instrument, 11 the music roll,.and 12 the winding roll, on which the music sheet 13 is wound during the operation of playing. The tracker 10 is provided with the usual ducts or apertures 14 adapted to cooperate withthe note sounding perforations in the mus c sheet. In the pres ,ent instance, it is also provided with five additional ducts, numbered 15, 16, 17, 18 and 19 respectively, located at the ends of the series of ducts 14 (see Fig. 1.). These five special ducts are connected by flexible tubes, omitted from the drawings for clearne s of illustration. for operating. five pneu matic bellows, numberedrespectively 20, 21,

22, 23 and 24, Figs. 1, 2 and 4. The conmotions of one of these tubes is clearly shown in Fig. 4 of the drawings, which represents the bellows 21. attached to a board or casing25, longitudinallyof which runs a chamber 26, which This bellows is is connected to a source of wind tension or I suction,'not shown. The flexible tube lead: 11] the under side of a diaphragm 27 ,-to which is connected the usual, double diaphragm valve 28 adapted to alternately open the from the tracker duct 16 is connected to f bellows 21 t0 the suction chamber 26 or k to atmosphere. I 1

Each of the a finger 29, which fingers bear against D- valve boards 30, 31, 32, 33 and 34 respectively. These are mounted on a board .35,

bellows 20 to 24 inclusive has longitudinally of which runs a suction chamberv 36. A port 37 for each of the valve boards is connected by a flexible tube 38 to a port or series'of ports 39, 391, 392,

393 and 394 controlling diaphragm pneumatics and valves as shown in an action casing 40, to be hereafter described, (see Figs. 7 and 9). The tube from board leads only to port 39; that from 31 leads to three ports 391, and similarly each of the others,-

32, and 34 leads respectively to three ports 392. three-ports 393 and three-ports 46, on which is pivoted adog 47 normally bearing against a stop 48. Pivoted on uprights 49, 50 (Fig. 1), shown as attachedto the ends ofthe board 35 is a U-sliaped rod 51 having rearwardly extendingarms252 at its upper ends, which are drawn downward by tension springs Secured fothe lower middle portion of the bar 51 is a curved finger 54 adapted to engage with the dog 47 on the lug 46.

Mounted in the present instance immc diately below the winding roll 12 is a series of four bars 55, 56, 57 and 58, each of which push buttons extend hrouglrthe casing. of

, is provided atits forward end with ushw button 59, 60, 61 and 62 respectively, w ich,

the instrument, as shown in Fig. 5, so as to be within convenient reach of the operator (see Figs; 1, 5 and 6). Each of the bars 55, 56 and 57 contains a D -valve 63 connecting a port 64 extending to a suction chamber, not shown, with a port 65. Each of the pm 65 is connected by a flexible'tube 66 with a port 67, 671 or 672 in the casing 40.

The bar 58, to which is attached the push button 62, is solid (see Fig.6). Each of the bars 55 to 58 inclusive is pressed forward by a spring 68. On each of the bars 55, 56

and 57 is a block 69 having its rear face 70 inclined. The bar 58 carries a block 71- of greater length than the blocks 69 and having its'rear face 72 similarly inclined. Pivotally mounted above the blocks 55 to 58 is a bar 73 having a downwardly extending lug 74 the bottoi clihed (see gs. 5 and 6). Connected With the push button 62 by means of a bell-crank action case of the instrument containing the usual pneumatic action.

lever 75, rod 76 and lever 77 is a valve 7 8 in the casing 40, (see Fig. 8), the function of which valve will hereafter appear.

The'casing 40 (see Figs. 3, 7 and 8) is the For clearness of illustration, parts are omitted, the striking playing, or operating pneumatics being inerated by a1r tension or suction. The aetion casing 40 is shown as provided near its lower portion with a chamber 81, connected to the high tension bellows or chamber, not shown, and extending the full length of the casin Immediately above thisare four cham ers 82, 83, 84 and-85, separated from each other by air-tight partitions 86. Above the chambers 82 to 85 are thirteen chambers marked 87 to 99 inclusive; At the-rear of the row of chambers 82 to 85 and. the row 87 to 99 is afchamber 100 running the entire length of the casing and connected ,by

means, not shown, with the low tension wind chamberor bellows. A suitable passage 101 leads from each. of the chambers 87 to 99 in: elusive to supply suction to groups of the pneumatics 79 and their respective pneumatic 'diaphragms and valves 80. Each of the chambers 87 to 99 inclusive is connected by a passage closed by a flap valve 102 with the low'tension chamber 10 The operation of my device is as follows: WVhen the music sheet 13 passes over the tracker 10 with imperforate portions thereof covering the five ducts 15 to 19 inclusive,

face of which is forwardly in thus be sounded-with the'normal force of the low tension or low wind of the instrument. Assuming, e. 9., that one of the perforations in the paper passes .over the aperture 16 in the tracker board, air will be admitted beneath the diaphragm 27 Fig. 4 to raise the double valve 28, which cuts off the pneumatic 21 from atmosphere and con nects it with the suction chamber 26. The

pneumatic 21 will thus be collapsed and. its

finger 29 bearing against the D-valve board i 31 willforce the same against the action of its spring so as to disconnect the port 37 from the suction chamber 36 and to open the same to atmosphere. Air will then pass through the branched tube 38-t0 the three ports 391 and will act to raise the diaphragm' valves in the chambers'88, 92 and 96 so as to connect the same with the chambers 88, 84 and respectively. If we assume. that one of these chambers, e. 9., the chamber 8 1,'

has previously been connected with the hi h tension chamber 81 by the raising of t e valve 671, it is plain that the particular striking pneumatics 79 connected with the chamber 92 will be connected to the high I tension chamber 81 and will sound their notes with increased force whenever their valves 80 operate to make them sound, that is, these notes will be accented. Obviously, the connecting of the chamber-92 with the high tension chamber 81 will act to close the flap valve 102 between the chamber 92 and the low tension chamber 100. But the valve 671 can only be'raised to connect the chamber 92 with the high tension chamber 81 by pressure on the push button 60', which acts, as already described, to force back one of the bars 55 so as to cut off the passage 67 from the suction passage 641 and to connect the same to atmosphere. It on the other hand all three push buttons 59, 60 and, 61

had previously been pushed back, it is, ob- V 1 vious that the striking pneumatics connected with all three chambers 88,92 and'96-would be subjected to the high tension. suction of the chamber 81.. In the same way a perforation in the music sheet 13 passing over the duct 17 in the tracker will act to open the chambers 89,93 and 97 to the chambers83, 84;- and 85 so that the simultaneous or previous pushing in of one of the buttons 59,

60 or 61 will act to open the corresponding chamber 89, 93 or 97, as the case may be, to the high suction. This is ofcourse equally the effect of .a perforation in the note sheet passlng over-the duct 18, which will open i an through a chamber 82'and its pneumatic valve shown above the port 39, with the chamber 81, so that whenever the tracker duct 15 is opened the pneumatic 20 and its valve 80 cause air to pass to port 39, thereby openin the valve above it and supplying high wind for the group of say 17 bass notes supplied from chamber 87. As the valve 39 connects the high tension chamber-81 with the chamber 87 through the chamber 82, the

latter two chambers being connected by open passages (see Fig. 7), these lower seventeen notes will be open to high tension and 'will, consequently be accented independently f the movement of any of the manual playing buttons 59 to As the push button 62 has the effect of opening the high tension chamber Sl'directly .into the lowtension chamber 100, it. is obvious that the pushing back of this button renders unnecessary any. opening of the ducts 15 to 19 in the trackers, and of itself opens all the notes of the instrument to high tension and causes them to sound with in creased force. i

The particular grouping of the connections between the ducts in the tracker board and the push buttons v above described is shown diagrammatically in Fig; 9 of the drawings. It is obvious that this grouping maybe varied within wide limits, it being advantageous thatithe groups of note-sounding devices in which the air pressure connections are selectively varied by the means antomatically" actuated by the note sheet should differ in number or position, or both from the groups connected with the push buttons. In this way any particular note, as a solo note, may be accented, it being unusual that notes immediately adjacent to the solo note should be struck therewith.

As a means for closing the valves controlling the admission of-air' to the chambers 87 to 99 inclusive, I have shown means illustrated' in Figs. 2 and 4 of the drawings. ,VVhen thebello ws 21 is collapsed by the registration of a perforation in the note sheet with the duct 16 it not only forces back the valve board 31, but also forces back the U- shaped bar 51 against the tension of the spring 53; This bar 51, as shown in Fig. 9,

- carries a curved finger 5 1 which first acts through the dog 47 and lug 46 to'tilt the board 43 so that its lug 44 is raised above the plane of the lug 41 on the valve board 31. 'As soon as the finger 54 passes the dog 47 the board43 is permitted to drop back to its horizontal position, in which its log 44 will engage with the. face of the lug/11 and hold the'fiboard 31 against the thrus't'of the spring shown in Fig, at. -When the bellows 21 distends to its normal position, as if shown, the dog 17 swings on its pivot pern'iits the finger 54 to pass idly thereby.

It is obvious that the next passage of a perforation 1n the music sheet over any one of the ducts 15 .to 19' inclusive will againlift f' the board 43 when the valve board 31,0r any particular back will be released and. thrust forward by valve board that has been thrust 1 its spring to the closed position shown in Fig. 4.

lnclusive. The first three of these, Nos, 59,

60 and 61, are connected with valve boards,

which carry blocks 69 adapted to pass to the rear of and pi vot as each push button Somewhat similar means are shown 11 Figs. 5, 6 and 8 for closing the valves 63' in connection with the push buttons 59 to 62- 1 be engaged by the lug on the bar 78, the bar being tilted on its is pressed" in-" wztrtllly. It is obvious that the pressing in of any push button will raise the bar and;

hence permit such bars as have previously been pressed back to be returned to their normal forward position by the action of' their springs 68. The push button 62shown M in Figs. 6 and 1 ofthe drawings has instead of the block G9 a bloc'kWL of considerable length, so that it acts to tilt the board 7 3 on its pivot and to hold it in its raised position, thereby releasing any or all of the othervalve boards 55, 56 or 57 which may the have been pressed back. For clearness, I have omI tted many familiar details of construction such as thefQ -O mounting for the'various valves that con? trol the pneumatic 7 9 and the chambers to and the guides for the various slid ing or D-valves, because such details are .1 well known in the art and the drawings. are; clearer without them.

pneumatics and valves may be of widely dlfierent forms without affecting the 'prin f ciples of the invention. It will be seen that each of the buttons 59, 60 and 6-1 manually controls the accenting of one ofthe three f groups of notes which have connection respectively with the chambers 83, 84, and

85, and that the special or accent ducts 16, l 17, 18, or 19 of the tracker control the admission of the high .wind or accenting windv 'totone chamber 88 to 99 of the four haying communication with the respective ohambers 83, 84, 85, each of the ducts simulta neously actuating the valves "of three of the chambers 88 to 99 and/controlling the commi'lnication 1 of those 7 three chambers with the chambers 83, 84, 85. Thus I provido two sets-ofmeans for accenting the notes, one set being manually controlled to determine a range or group ofniotes whefei: the accent ]S to fall, and one set eing auto linatic means for determining the subdivi-fl sion of that group that is to be-accentedal These accentmg means are additional, of; 1

So also the various A course to the normal wind connections de-" scribe and to the valves 80 which cause the playing or silence ofthe individual notes,

It- -is obvious that many' -m echanical changes may be-ma'dein the embodiment of my device, as well. as in the grouping and arrangement of the various connections,

. without departing from the spirit of my invention. It will also be understood that by the phrase group of note sounding de vices or the like I intend to include any desired number of such note sounding deincluding parts of twoor more of the first vices (one or more) less than the entire number.
