To (LZZ whoiii/ it pray concern..-
Be it known that I, Munnrrr GALLY, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Mechanical Musical Instruments, of which the following is a specification, reference being had therein to the accompanying drawings.
In the accompanying drawings, Figure 1 is a side view of an instrument embodying the features of my invention. Fig. l is a transverse section showing the construction of the swell-motor. Fig. 2 is a transverse section of the exhaustair chest, showing the bellows, pneumatics, and reed-valves, also the trackcrrange, inclosed grooves, reeds, &c, Fig. 3 is a transverse section of a traeker-range,showing its ducts leading into inclosed grooves, which terminate in pneumatic motors. Fig. 3 is a modification showing tracker-range ducts operated by finger-keys. Fig. 3" is a modification showing tracker-ducts operated by means of music-sheet and valves connected directly therewith. Fig. 4 is a plan of the grooved board with parallel grooves; Fig. 5, a modification of grooved board having diverging grooves. Fig.6 is a perspective of combined tracker and grooved board, both having diverging grooves; and Fig. 7 is amodiiication of the construction of Fig. 2.
In a small organ it has been found very difficult to construct and arrange the exhaustpumps of the bellows in a manner to produce sufiicient exhaust for the perfect operation of the instrument. It is also necessary, when pumps are operated by crank, as shown in drawings, Fig. 1, to have at least three pumps, in order to secure a steady motion to the crank. Three pumps, placed on the surface of reservoir F, would be so narrow that their folds would injure their capacity for properly exhausting the instrument. To obviate this defeet I use only two pumps, G K, on the face of the reservoir F, and place a third pump, L, at the end of the reservoir, as shown. The dotted lines show the position of the leader from reservoir F to pump L. Pump L is shown at tached for support to the end of wind-chest A; but it may be attached, if preferable, directly to the end of reservoir F. Motion is given to pumps G and K by means of pitmen N and M, operated by cranks I? of crank-shaft l e. I make a slot in pitman II, or in a piece attached thereto. A pin, (1, projecting from the side of pump L, enters the slot of pitman N. The moving pitmau, in connection with the pin, produces the movement of the pump L, the three pumps operating in proper time to secure a steady motion to the crankshaft, and also producing a proper amount of exhaust.
The valves E for the sounding devices, as shown in Fig. 2, are placed within the exhaustchest A, and are held to their seats by means of springs 0. These valves are operated by means of bellows-shaped pneumaties D. Two reed-boards, B 8, each contain a part of the scale represented by the range of the tracker H. In an ordinary manual reed-orgau the reeds are placed as near together as possible, in order to correspond in. position with the finger key-board. Pneumatic motors made narrow enough to correspond with such an arrangement of reeds would be weak in their action and would not open the reedvalvcs unless very nicely and carefully adjusted. To avoid the necessity of such careful adjustment I make the pneumatic motors wider and space the reeds to correspond, as shown in Fig. With only one reed-board for the entire scale, the instrument, with these spaced reeds, would be much too long. I therefore divide the scale and use two reed-boards, B. placed opposite each other, as shown in Figs. 2 and 7, and place the pneumatic motors in two lines be tween them, one line of motors for each reed board.
In Fig. 2 the pneu matic motors D shown attached di rectly to the plane :l'ace of the valveboard; but in Fig. 7 a recess shown in the valve-board in which the two lines of pneumatics are placed, allowing the valves to pro ject directly under them.
In my application for patent filed October 30, 1882, I describe inclosed grooves leading from pneumatic motors toward the trackerrange or operati ug-keys. In Figs. 2 and 3 of the present case I show a similar construction of grooves having tracker-range II attached to the grooved board, the ducts of the tracker leading directly into the grooves. Fig. a
shows a plan oi the grooves arranged parallel to each other, the position of the pneumatics being shown bydot-tcd lines.
Fig. is a niodification, showing diverging grooves. Fig. 6 is a perspectiveshowing the tracker-range H, having diverging ducts leading into diverging grooves in grooved board 0. I use this construction when the scale of the instrument is Verylong. To attempt to reach directly the V pneumatics of a long scale by meansof diverging ducts in the trackerrange would require a tracker-range too high to be conveniently placed in an ordinary instrument, and to de pend alone on diverging inelosed grooves in the grooved board with parallel ducts in the tracker-range wouldmakc the grooved board for a long scale too wide for an ordinary instrument. I therefore use, when desirable, the modification shown in Fig. 6, combining the tracker-range having diverging duets with the grooved board having diverging grooves.
The ducts of the tracker-range may pass into the diverging grooves of the board only on one side of the tracker-range, or may alternate, passing into grooves on both sides of the trackcr-range, as indicated by the dotted lines.
In using the trackerrange and grooved board combined I employ either the parallel or the diverging grooves or ducts, as the case may require.
To operatethepneumatic motors I use either the perforated music-sheet V, Fig. 2, directly in connection with the tracker-range or the music-sheet in connection with valves on the face of the tracker-range, as shown in modifi- V cation, Fig. 3*, or operate them by means of finger-keys, as shown in modification, Fig. 3. In using the valves V on the face of the tracker-range, I hinge them on one side, as shown. The valve is held open by means of a spring, a, unless held closed by means of the pressure of the music-sheet V. When a perforation in the music-sheet passes over the spur of valveV" the. spur passes into the perforation and the valve opens.
The letter (1 indicates the music-sheet rest.
In Fig. 1 is shown the large pneumatic motor X, which operates the swell or swells of the instrument. This motor is operated indirectly from the tracker-range through a small sensitive pneumatic, Y. The construction is more particularly shown in Fig. 1. As I describe and claim, broadly, in previous patents this method of operating the swells, I will only describe specifically the present construction and arrangement. The large pneumatic X is placed on the Valve-board outside of the airehest A, and the small operating-pneumatic Y is placed within the chest, as shown. The duct 6 leads to the tracker-range and the small duct 19 to the interior of the air-chest A. This duct 1) may lead through the movable board of the pneumatic, if desired. The operation i will be the same. When the pneumatic Y ns valve 12, thelarge motor-pneumatic Xis hausted and opens the swell W. In my patents of April 8, 1879, I produce Ieturn movement of the motor-pneumatic means of the return movement of the pneumatic Y,and in my patent of N0- vember 25,1879, I produce the return movement of themotor-pneumatie X by means of a duct from the track er-range directly to-the 1notor-pneumatic. In the present case I either connect the motor-pneumatic by a duct to the tracker-range for the return movement, or use the more-quicklyaeting device shown in Fig. 1*. The small primary pneumatic h connects with the tracker-range through duct m. This primary pneumatic operates the valve 71*, which opens a-duct from the interior of the motor X to the external atmosphere.
the motor may remain collapsed after the re turn movement of pneumatic Y until it is desirable to inflate it, when it may be quickly or slowly done by means of the primary pneumatic h. l
The operation of the pneumatic motors D, Figs. 2 and 7, depends upon the dift'erence'in air-pressure on the two sides of the follower or movable board of the pneumatic, caused by the opening of duct t to the external atmosphere, duetf being much smaller than duct t, in order that the air passing through the music-sheet may be in excess of that passing through duct f. This is broadly covered by claim 3 of my patent of April 8, 1879. The position of ductfis immaterial, whether as shown in Fig. 2 or as 19, Fig. 1, the effect is the same. I sometimes lead the duct 19 directly into the duct t, near the pneumatic, as shown at 1',Fig. 4.
The principal feature of the pneumatic action in the present case is its arrangement and combination with other parts to produce a Thus compact instrument of cheap and durable conalso bearing the reeds and reed-valves, com-' bined with a series of pneumatics which connect with the grooves in the board and also with the reed-valves.
2. The combination, with the reservoir-bellows, of a pump operated by crank and pitman, and the supplemental pump L, arranged substantially as specified.
3. The combination, with two reed-boards and valves for each board, of the recess in the valve-board between the reed-boards containing pneumatic motors for operating the valves.
4. The combination, with thegrooved valveboard having inelosed grooves, of the trackerrange attached thereto, the inelosed grooves leading from the ducts of the tracker-range to the pneumatic motors.
5. The grooved board having air-passages and reed-apertures therein and tracker-range attached thereto, in combination with pneumatic motors in the wind-chest, connected with said passages and serving to operate the reedvalves, which are also in the wind-chest, a
single board thus constituting the support for the entire system of reeds and valves, snbstarr tially as described.
6. The combination, with a grooved reed and valve board and a tracker-range placed transversely thereof, of a series of pneumatic motors on said board, each connected with its proper groove in the reed-board, and a line of reeds at each side of said board outside the pneumatics, substantially as described.
7. The combination, with thetracker-range, ot'the grooved hoard having diverging grooves.
S. The combination, with the tracker-range having diverging ducts, of the grooved board having diverging grooves.
9. The combination with the reservoir-bellows, of a pump arranged horizontally, connected with the reservoir, and a pump placed vertically at the end of the reservoir, with a crank and slotted pitman, said pitman attached to the horizontal bellows and operating the vertical bellows by means-of a pin working in the slot.
in. The combination, with the swell or swells XV and the pneumatic motor X. of the primary pneumatic Y, all attached to the reedboard, substantially as specified.
11. The combination, with the tracker-range, of a reedboard countersunk on the under side, the pneumatics inclosed in said countersunk portion, and the reed-valves pivoted directly to the board and bearing on said pneumatics, as set forth.
12. The combination, with thetracker-range, of avalve hinged thereon,a spring connected with the valve and range to lift said valve, and a projection on said valve to hold the same down until permitted to rise by a perforation in the sheet, as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
