SPECIFICATION forming part of Letters Patent No. 647,926, dated April 1"?, 1900.
Application filed April 20, 1898. Serial No. 678,228. (No model.)
To all whom it may concern:
Be it known that I, ROBERT W. PAIN, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Musical Instruments, of which the following is a specification.
My invention relates to musical instruments, and more particularly to a melodystop for automatic musical instruments.
I will describe a musical instrument embodying my invention and then point out the novel features thereof in the claims.
In the accompanying drawings, Figure lis a sectional elevation of a portion of a musical instrument embodying my invention.l Fig. 2 is a horizontal sectional view taken on the line 2 of Fig. l. Fig. 3 is also a horizontal sectional view taken on the line 3 of Fig. l. Fig. 4 is a vertical cross-section taken on the line 4 4 of Fig. l.
Similar letters and numerals of reference refer to corresponding parts in allthe figures of the drawings.
In the following my invention is described in connection with an -automatic organ the reeds of which are caused to speak by an exhaust. It will be understood, however, that the same results could be accomplished by forced air, the operation of the parts being opposite to that described in connection with an exhaust.
A represents an exhaust chest or chamber, B a tracker-board, and O a perforated sheet movable over the tracker-board.
c represents a motor for moving the perforated sheet over the tracker-board. The passages in the tracker-board are in communication with an equal number of passages c', and at the other end of each passage c is a pneumatic c2. As the perforations in the sheet pass over the passages in the trackerboard air is admitted to the pneumatics c2, which then operate to move a train of parts to open the reeds to the exhaust, and thus cause them to speak. The same arrangement of parts is had. for each reed, so that the following description of one train of parts will apply equally to all:
D represents a pallet which when it is moved by a pneumatic c2 opens a pneumatic d to the exhaust A and closes a vent cl2 of the pneumatic to the atmosphere. The pneumatic d in turn moves a lever d3, carrying a pallet d4 to open a reed J to the exhaust A, which causes it to speak.
In addition to the set of reeds J of the organ I provide a second or supplemental set or series of reeds of preferablyahigherpitcli,which I term solo or melody reeds. These reeds are caused. to speak by an exhaust, though forced air may be employed, and they are controlled by the perforated sheet O.
G represents one of the series of solo or melody reeds, g an exhaust chamber or chest,
and g a pallet normally closing the reed GV to the exhaust. Fach reed G is provided with a pallet g', which is moved by a train of parts. The same arrangement lis had for each pallet, so that the following description of'one arrangement will apply to all.
H represents a pneumatic, which when it is operated moves a lever g2 to raise the pallet g. Passages h h2 form a communication between the pneumatic I-I and a chamber h, which is connected with an exhaust. A valve 7c', carried by a stem K, normally closes the vent h4 of vthe passage 71.2 to the chamber h, while a valve 7o permits a vent h3 from the passage h2 to the atmosphere to be normally open. When the valve-stem K is shifted, the vent h3 will be closed and the vent h4 opened, so that the exhaust through chamber 7L will operate the pneumatic Il.
L represents a pneumatic for moving the stem K. This pneumatic is in communication with the exhaust A through port Z2, passage Z, and tube Z., the end of which is closed byapallet D to the exhaust. Thus the sounding of a reed G is controlled by the perforated sheet O, for when the pneumatic c2 is allowed to operate a pallet D the pallet D opens a tube Z to the exhaust to operate its pneumatic L. As the pneumatic shifts its valve-stem K a pneumatic II will be opened to the exhaust in a chamber 7L and operated to lift a pallet g.
In operating the melody-reeds it is preferable that only one reed thereof be sounded at a time, which reed should sound the air or melody note. This l accomplish by having all the chambers 7L in communication and exhausting through all of them the current passing from the chamber of the lowest note of the bass or subbass through the intermediate chambers to that of the highest note of the treble-that is, the exhaust will be from the chamber 7i, with which the pneumatic ll of the lowest note of the bass is in communication through the chamber 7L belonging to the pneumatic H of the next lowest note, and so on to the chamber 71, of the highest note in the treble, with which chamber the exhaust is connected. Thus if the exhaust is broken in its passage through the chambers the pneumatic H belonging to the chamber h next to the chamber 7L from which the exhaust is cut off will be operated to open its reed to the exhaust through chamber g.
The several chambers 7L are in communication with each other through channels 7L, As
shown in Figs. 2, 3, and 4, the channels are arranged diagonally, so that the opposite ends of adjacent chambers will be connected. The direction of the current through the chambers 7L and channels 72. (see Fig. fi) may be described as follows: Beginning for convenience at chamber 3, the current passes up through the port over the front end of chamber 3 into the third diagonal channel, down through the port over the rear end of chamber 2 into chamber 2, through chamber 2 to the front thereof, through the port over the front end of chamber 2, through the second diagonal channel, through the port over the rear end of chamber l, through chamber l, through the port over the front end of chamber 1, and through the first diagonal channel to pipe l', so that should the exhaust be interrupted through any one of the chambers the pneumatic H belonging to that chamber would be caused to operate.
On the Valve-stem K in each chamber 7L l have provided a valve 7a2 for closing the port between its chamber and the diagonal channel leading from the adjacent chamber in a direction opposite to the direction of the exhaust. I also provide a port or Vent for each channel to the atmosphere, which is closed by a pallet hg. This pallet is moved by an extension of the Valve-stem K.
M represents springs on the Valve-stems K for returning the valves carried thereby to their normal positions.
The air or melody note is generally the topmost note of a chord, and the perforation of that'note is made in the sheet near that edge which passes over the passages in the trackerboard leading to the treble reeds of the organ.
The operation, briefiy stated, is as follows: As the perforation indicating the air-note passes over a passage in the tracker-board air is admitted in that passage to operate the pneumatic c2 at the end thereof to set in operation the train of parts to cause the air-reed of the organ to speak. Simultaneously as the pallet D of that reed is opened the exhaust A operates through the tube/ opposite it to collapse the pneumatic to shift the Valves on the stem K, connected with it. For example, should the Valves in chamber 3 be shifted Valve 7a2 therein would close the passage h, leading from chamber t and Vent that passage to the atmosphere. The exhaust would then start from chamber 3 and cause the pneumatic H belonging to that chamber to operate and open its reed to the exhaust through chamber g. As long as the valve 7.1 leaves the port h4 open its pneumatic H will be held collapsed. As soon as the perforation of the melody in the paper has passed over the passage in the tracker-board the air will be shut off from its pneumatic c2, which will then collapse and allow all the parts to return to normal position.
lVhat l claim as new is l. .ln a musicalinstrument the combination of a set of reeds or analogous devices, a special set of reeds for emphasizing the air or the bass, each special reed corresponding to one of the first-named set, a pneumatic chamber for each special reed, passages by which an air-circuit may be caused to pass in succession, through pneumatic chambers, a Valve for each pneumatic chamber adapted when opened to effect the speaking of the corresponding special recd,a second Valve for sluitting off the passage connecting with the succeeding chamber, a pneumatic motor for multaneously operating` both the said Valves, a second pneumatic motor for causing the speaking of the corresponding reed of the first-named series, a third pneumatic motor controlled by a corresponding channel in a tracker-range, and means operated by said third motor for simultaneously actuating the said first and second motors, whereby when two or more channels of the tracker-board are opened all of the correslionding reeds of the first-named set are sounded, but the first only of the corresponding reeds of the special set is sounded.
