SELF-PLAYING MUSICAL ENQTRUMENT- Application filed August 19, 1905.

To all whom 732; may concern:

Be it known that I, HARRY M. SALYER, a citizen of the United States, residing in New York' city, borough of Bronx, New York, have invented certain new and useful Improvements-in Self-Playing Musical Instrution.

I, My invention relates to improvements in the class of-pianos wherein pneumatically ophammers through the medium of a roll of perforated paper. v

One of the objects of my invention is to cause, the hammers and associated parts of the action to respond accurately and promptly to the action of the operating pneumatics, and also to permit positive disconnection of the operating pneumatics from the piano action when the piano is to be played manually; and further objects of the invention are to compactly arrange the main automatically operating parts in the space above the mit ready accessibility to the various members controlling the operating parts, and generally to improvesuch class of pianos.

My invention comprises the novel details and arrangements of parts and their relation to the manual keys and strings as more fully the claims. I

form of finger 26, Fig. 1 1 is a perspective view diagrammatically illustrating the relation of parts for controlling the automatic playing devices, Fig: 12 is a detail plan view of part of the governor for the music-sheet operating motor, Fig. 13 is a central section, enlarged, through the bellows 82, Fig. 14 is a central section, enlarged, through valve casings 88 and 89, Fig. 15 is a section of the valve 90, Fig. 16 is a section through valve 94, Fig. 17 is a detail section, enlarged, of valve 108, Fig. 1% is an enlarged section of casing 115, and Fig.19 is an enlarged section of the governor valve devices.

Similar numerals of reference responding parts in the several views.

1n the drawings 1 indicates the piano casing which may generally be' of any well known construction, and in the example shown the upwardly and rearwardly inclined top frame or front board 2 of the casing has a centrally disposed opening 3 adapted to he closed by a door a, which may slide upward in guides 5 to permit access to a receptacleo, disposed .behind the opening 3 and adapted to contain music-sheet operating rolls 7, 8, and the tracker 9, said receptacle being above the shelf 10 and above the manual keys 1-1. in the space forward of the strings behind the top frame 2. The latter also has openings 12,13 shown on opposite sides of the opening '23 and preferably having doors 1-41, 15 providing ready access to certain devices to be operated for controlling the automatic playing of the piano as hereinafter explained.

g The; operating pneumatics 16 and their primary and secondary valves and. wind chests 16, which may be of any Well known construction, are located in the spaceabove the keys-and forward of the strings 17, and

indicate corforward of the prolongs or abstracts 18 that action will have positive movement to accord with the movements of .the corresponding pneumatics, and whereby said arms 21 may be moved out of operative engagement'with the wippens for manual playing.

As shown clearly in Figs. 5, 8 and 9 the arms 21 are pivotally connected, as by links 22, with a rocking bar 23 longitudinally disposed in front of the abstracts and above the operating pneumatics 16, and supported, as by hinges 24, so as to rock up and down, each link 22 being shown connected with a' projection 25 carried by the bar 23. The arms 21 are shown provided with fingers 26 adapted to enter recesses 19 in the wippens 19, which may be provided with felt or the like 27. The finger 26 is preferably made adjustable with respect to its arm 21 to regulate the proper relation of the arm to the wippen, and for this purpose the finger 26 may be provided with screw threads to screw into the arm 21 as in Figs. 5, 6, 8 and 9, or thefinger 26 may be adjustable on arm 21 by means of screw and slot connection 28 as in Fig. 10. The arms 21 are also adjustably and movably connected with the fingers l6 of the pneumatics 16 so that said arms may rock, and for this purpose 1 have shown screws 29 projecting from arms 21 through openings in the fingers 16 and provided with rounded nuts or buttons 30 on opposite sides of said fingers, whereby said arms may be adjustable with respect to the collapsed positions of the pneumatics 16, will rise and fall co-extensively and in unison with the corresponding pneumatics, and may swing sidewise relatively to the fingers 16.

At 31 is a handle connected with bar 23 and shown extending forwardly in line with the opening 12 in top frame or front wall2 of the casing, a suitable catch 32 serving to en gage handle 31 to hold bar 23 in position to maintain the arms 21 and their fingers 26 in operative connection with the wippens, as in Figs. 5 and 9. .The arrangement is such that when. the arms 21 through their fingers 26 are in operative engagement with the wippens, as in Figs. 5 and 9, the action may be operated by the pneumatics 16, the prolongs 18 will move independently of the manual keys 11, and the hammers, dampers and associated parts of the action will move in perfect unison and accord with the operation of the pneumatics so there will be no dclayed action of the hammers, dampers, etc. with respect to the pneumatics. When it is desired to play the piano manually the handle 31 will be raised, bar 23 will swing downwardly and withdraw the fingers 26 from the wippens, and the action will then be free to be operated by the keys without interference in any manner by the automatic playing mechanism.

In order to limit the upward movement of arms 21 and the wippens by the pneumatsmear ics 16, and also to prevent the pneumatics 16 from operating the arms 21 to the injury of the action while. the arms 21 are released from the wippens, I- provide stops 33 on the bar 23 over the corresponding "arms 22 to stop the upward movementof said arms during automatic playing, and said stops may be adjustable. l have shown said stops in the form of screws carried by bar 23 and having heads at the lower ends which may be provided with felt. Said stops are also in such position with respect to arms 22 that when bar 23 is lowered as in Fig. 8 and arms 21 are out of operative engagement with the wippens, said stops will prevent the arms 22 from rising if the pneumatics should be operated, thereby preventing the fingers 26 from engaging the wippens.

To keep the manual keys 11 from moving while the piano is being played automatically I have shown a bar 35 extending along the rear ends of the keys and having a flange 35 over-lying the keys, said bar being provided with one or more slots 36 arranged at an angle to the length of the bar and receiving a pin or pins 37 projecting from a bar 38 that is guided to slide on the part 39, as by means of screw and slot connection 40, whereby as bar 38 is moved in one direction pins 37 in connection with slots 36 will cause bar 35 to rise and lift the flange 35 from the keys, as in Fig. 8,- and when bar 38 is moved in the other direction flange-35 will be drawn down upon the ends of the keys to keep the latter from moving. Bar 38 may be operated in any convenient manner. 1 have shown the same provided with a pin 41 engaging a lever 42 pivotally supported as at 43 and extending under the front part of the casing in convenient position to be operated for sliding bar 38 back and forth.

At 45 is a pneumatic motor for operating the music-sheet rolls 7, 8, and shown located in the space forward of the strings behind the top frame 2 and above the receptacle 6, the motor shaft 46 having a sprocket 47 from which chain 48 passes over sprocket 49, on

the shaft 50 that is connected by suitable gearing with said rolls for operating them in any well known manner. The lever 51 pivotally supported at 52, has an arm 53 passing through the side wall of receptacle 6 and projecting within said receptacle in convenient position for operation, said lever being loosely connected with a sliding bar 54, mounted upon the top of receptacle 6, by a rod 55 having nuts 56 adapted to engage a projection 54 through whichrod'55 freely passes, said nuts being at a distance apart to permit rod 55' and lever 51 to have movement independent of bar 54. Bar 54 also operates a clutch 57 to engage and disengage shaft 46 and a sprocket wheel 58 over which a chain 59 passes to sprocket wheel 60 on the shaft 61 of a governor for motor 45. The arran ement is such that when arm 53 is moved the governor while at the same time coupling clutch 51 for the re-winding roll 7 and when rod 53 is moved to the right in Fig. 4

the clutch 51 will be coupled for operating.

winding roll 8simultaneously with the'coupling of clutch 57 for throwing the governor into coaction with motor 45, and uncoupling clutch 51 from roll 7. Shaft 61 carries a worm wheel 62 (Fig. 12) that meshes with a worm 63 connected with ball governor 64-. for rotating them, the arms of which governor connect by a block 65 and rod 65- with valve 66.

The governor valves are shown in Fig. 19, wherein a port 67 connects by a pipe 68 with motor 45, and a port 67* connectsby a pipe 69 with pipe or trunk 70 of foot bellows 71. The slide 72 has ports 72, 72 registering with ports 67, 67 and ada ted to communicate with the cavity 66 in slide valve 66. To control the speed of motor 45 at will by reason of the flow of air through pipes 68 and 69 the movable part 72 of the governor valve is connected by a rod 73 with a crank 74 connected by a link 75 with a lever 76 having a hand piece 77, whereby the movable part 72 may be shifted. As the motor rotates the ball governor 64 will be rotated by the connected gearing and thereby valve 66 will be caused to provide more or less communication between pipes 68 and 69 to govern the speed of the motor. To alterthe speed of the motor at will lever 76 is shifted so that the connecting rod 73 will shift ports 72 and 72 and more or less open communication with cavity.66 to permit more or less air to flow from the motor through pipes 68 and 69 according to the speed of the motor desired, the ball governor and valve 66 serving at all times to controlthe flow of air permitted by the relative positions of ports 72 and 72 with res ect to cavity 66. A spring 65 coacts wit the ball governor 6 1. I On lever 76 l is a brake shoe 78 adapted to bear against worm 63 to check the rotation thereof when said lever 76 moves slide 72 sufiiciently far to stop air flow from port 72 to cavity 66, stopping the motor and checking the mo mentum of shaft 61. Lever 76 and its han dle 77 are shown located on shelf 10 in the space behind opening 13 in the front wall or 4 board 2 in convenient position for operation,

and may be concealed by the door 15.

The air for the operative pneumatics 16 is controlled by the foot bellows 71 and trunk 70 through the medium of a storage bellows 80 and low pressure bellows 82 connected with said trunk, in well known manner, a pipe 81 providing communication between 5 said bellows and said pneumatics, (see Fig.

11). The pressure in bellows 82. is controlled as desired by means of a valve device I within said bellows connected by link 84. and lever. with a shifting handle 86 shown guided in a slot in shelf 10 and having its operative end located within the compartment behind opening 12 in the top frame 2 (see Figs- 1, 3 and 11), whereby when handle 86 is shifted as to the left in Fig. 11 the-pressure in bellows 82 will be reduced and when shifted as to the right the pressure will be increased. As shown in Fig. 13 the valve device within bellows 82 consists of a slide valve 83 connected with rod 84 and having a port or cavity 83 thatcommunicates with a port 7O leading to trunk 70, and valve 83 has a port 83 opening through the side thereof adapted to be controlled by a lever 83 pivotally supported within the bellows 82 at the side of valve 83 as from the stationary board of the bellows at 83 on a bracket 6, a link 83 pivotally connecting lever 83 with the movable board 82 of bellows 82. A pipe 87 connects the chamber in the bellows with a valve casing 87 that is connected by branch pipe 81 with ipe 81. The air entering the chamber of beliows 82 from the pneumatics 16 through pipe 81 and valve casing 87 passes into trunk 70 through ports 83, 83, and 70*, and the action of said air in connection with the expansion spring 0. causes the movable board 82 of the bellows to operate to actuate the lever valve 83 and the degree of suction maintained in the/chest of the primary and secondary valves 16 of the operative pneumatics 16 is controlled by the position of the slide valve 83 'with respect to lever 83 in its relation to the port 83. Thus, the nearer valve 83Fis adjusted by lever 86 toward spring a the greater degree of suction will be' required to cause lever 83 to co-act with port 83 to cut off suction through said port into trunk 70, owing to the position of the link 83 which gives the thrust from 82 to the lever 83, and whereby when suction is properly cut off spring a will by expanding cause the movable board- 82 to withdraw lever 83 from said port 83 to permit freer flow of air through said port, re sulting in a greater degree of exhaust from the pneumatic action, and the more valve 83 is adjusted away from spring a, the less -.pneu'matics is caused, and to this end i provide controlling valve 88 illustrated in section in Fig. 14, into Which-the pipe 81 leads by a branch pipe 81 which opens into a chamber 88 on one side of diaphra m 88 adapted to close pipe 81 pipe88 eading from chamber 88 to trunk whereby when pipe 81 is open in chamber 88 full exhaust from bellows 71 is permitted to communicate with the wind-chests of the pneumatics. To control the high exhaust through valve 88 at will I provide controlling valve 89 which has a chamber 89 connected by pipe 89 with chamber 88 in valve casing 88, and chamber 89 of valve casing 89 connects by pipe with bellows 80. At 89 is a rod having a valve 89 normally closing the port 89 between chambers 89 and 89, and said rod also has a valve 89 adapted to close a port 89 communicating with the atmosphere, 89 being a guide for rod 89*. Within casing 89 is a diaphragm 89 on one side of chamber 89 providing a chamber 89 that communicates by a pipe 92 with a valve casing to admit air into chamber 89, a small equalizing hole 89 in diaphragm 89 permitting the pressuresin chambers 89 and 89 to equalize when the valves 89 and 89 are in normal lower positions. Valve casing 90 (Fig. 15)

has avalve 9O adapted to control the opening of pipe 92 by means of a spring-Icontrolled push button 91 normally holding valve 90 against pipe 92. During the normal playing of a piece the suction through bellows 82 is utilized, and then the suction through pipe 88 into trunk'70 causes'diaphragm 88 to close against branch ipe 81 to shut ofi direct communication etween pipe 81 and trunk 70, because atmospheric air can enter chamber 88 through pipe 89 from chamber 89 and port 89 of valve 89. As soon as accentuation of a: piece being played is desired button 91 is pushed, unseating valve 90, and opening pipe 92 to the atmosphere, whereupon air rushing into chamber 89 of casing 89 raises diaphragm 89' by reason of the suction maintained through pipe 80 and bellows 80, thereby raising valve 89 from its seat, opening port 89 and causing the suction from bellows 80 through ipes 80 'and 89 to ,equ'al'ze pressure in t e chambers 88 and 88301 valve casing 88, diaphragm 88 then permitting air from the chests of the operativepneumatics to pass by lpipe 88 into trunk .70 under high suction. he length of time button 91 is held down controls the duration of the expression 'desired in the piece being rendered' As soon as button 91 is released valve 89 will close port'89 and then diaphragm 88 will again close against pipe 81 and playing by reason of the ordinary suction through bellows 82 may be maintained.

When it is desired to cause re-rolling of the in valve casing 94, (see Fig. 16).

sin-.261

playing the piece reversely during the re-rollmg, I provide the following arrangement: Valve casing 87 is of the same construction as shown in Fig. 14 with respect to casing 88, the pipe 81 entering casing 87 in manner similar to' pipe 81 incasing 88, pipe 87 corresponding to pipe 88 and the diaphragm within casin 87 corresponding to the diaphragm 88 mite action in connection with pipe 81 Pipe 93 connects the lower chamber in casing 87 below its diaphragm (corresponding to chamber 88 with chamber 95 In casing 94 is a rod 96 having a valve 97 normally closing a port 98 connecting chamber 95 with the atmosphere, and rod 96 also has a valve 99 normally unseated from a port 100, but adapted to seat against said port during rerolling, at which time valve 97 opens port 98. A chamber 101 in casing 94 provided with a diaphragm 102 connects by pipe 103 with bellows 80, and-a chamber 104 on the opposite side of diaphra m 102 is connected with a pipe 105, said dlaphragm having an equalizlnghole 102. Said pipe 105 leads to a valve casing 106, and pipe 105 has a branchv 107 controlled by valve 108 (see Figs. 11 and 17). As shown in Fig. 17, pipe 107 leads toa port 109 in casing 110 controlled by valve 108 which normally closes said port, and valve 108 is controlled by a finger 111 carried by shifting-lever 51 in such position that when the lever51 is in the position shown in Fig. 4 andclutch 51 is in engagement to operate the rewinding roll 7, valve 108 will be unseated toadmit air to pipe 105, and when lever 51 is shifted to the position for causing the roll 8 to wind the music-sheet, finger 111 will be drawn back to permit valve 108 to close to prevent air entering pipe 105 through port 109. Valve casing 106 and the devices therein are similar to valve 89 illustrated in Fig. 14, and pipe 112 leads from a chamber in valve 106 corresponding to chamber 89 to a chamber 113 on one side of a diaphragm 114 in a casing 115 arranged substantially similar to casing 88 and its diaphragm and parts, diaphragm 114 closing against aipipe 116 in chamber 117, which pipe communicates with pipe 68. A pipe 118connects chamber 117 of casing 115 with pipe 69, and a pipe 119 connects chamber 117with a chamber in casing 106 corresponding to chamber 89 in casing 89, pipe 105 communicating with a chamber in casing 106 corresponding tochamber 89 in casing 89. The operation of the parts above described is as follows1- when lever 51 is shifted to the position shown in Fig. 4 for re-winding the music-sheet on roll 7 valve 108-will open port 109 and atmospheric air will be admitted to pipe 105, whereupon air entering chamber 10']. in casing 94 causes valve 99 to close against the port 100 and valve 99 opens port 98, allowing being played atmospheric air to enter chamber and passpneumatics so that playing will not occur during re-rolling bf the music-sheet, and at the same time air in pipe will enter the chamber in casing 106 corresponding to chamber 89 causing the diaphragm corresponding to diaphragm 89 in Fig. 14 to 0pcrate the valve corresponding to 89 and open the port correspondingto 89 and close the port corresponding to 89 whereupon the pressures on diaphragm 114 will be equalized, whereby direct communication will be established from the motor from pipe 68, through pipe 116, chamber 117, and pipe 118 to pipe 69, and thence to trunk 7 0 for operating the motor at high speed for quickly rerolling themusic-sheet. Pipe 119 supplies suction for the chamber in valve 106 corre.- sponding to chamber 89 to cause the corre sponding diaphragm to operate the valves when air enters pipe 105. In said position of lever 51 clutch 57 is uncoupled so that the motor is no longer controlled by the governor, and the motor can run free. 7

To provide means for conveniently operating the damper mechanism of the piano action 01' sustaining pedal while the-feet are being used for operating the bellows 71, and to permit such damper action to be operated in theordinary way'by foot when the piano is manually, 1 provide the followmg arrangement the damper rail 120 and damper rod 121 arranged in any well known manner (see Figs. 5 and 11), are shown connected with a lever 122 supported by a spring 123 connected by a rod 124 with a foot pedal 125, whereby when said pedal is depressed the dampers 120 will be lifted oil the strings. The rod 121 .passes loosely through an opening in lever 122 and has a shoulder bearing against the'same, and r0 121 is adapted to be lifted by-a lever 126 cpnnected by a .rod 127 with a projection 128 carried by the movable part of a bellows 129, which may be operated by any suitable pneumatic mechanism, such as being connected with. bellows 71 by pipe 130. The pneumatic mechanism of said bellows, which may be of any well known construction, indicated generally at 131, is connected by a pipe 132 with a valve 133 similar in construction to valve 90, 91, and so arranged that when the button 134 is pressed air will be admitted into pipe 132. Thus, when the piano is being played automatically and it is desired to lift the dampers oil the strings, button 134 will be pressed and air passing through pipe 132 causes the bellows 129 to collapse, which by pulling upon rod 127 will operate lever 126 to raise damper rod 121 to operate damper rail 120.

The valve 133 is shown located on the shelf 10 adjacent to the handles 31 and 86, behind the opening 12 in the top frame or front board 2 in convenient position for operation. The valve 90 as well as lever 76 are shown located behind opening 13 in the top frame 2 i on the side of opening 3 opposite opening 12 in convenient position for manipulation, being shown'supported upon shelf 10. Shields 135 may be provided behind the openings 12 and 13 to conceal the interior mechanism and exclude dust.
