MOTOR FOR MECHANICAL MUSICAL INSTRUMENTS.
SPECIFICATION forming part of Letters Patent No. 722,196, dated March 3, 1903. Application filed September 9, 1902. Serial No. 122,682. (No model.)
To all whom it may concern.-
Be it known that I, JOSEPH COURVILLE, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Motors for Mechanical Musical Instruments, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to new and useful improvements in a motor specially intended for mechanical musical instruments forthe purpose of propelling the perforated shee over the tracker-range.
The invention consists particularly in the construction of the valvecasing and'the valveaction and also in the combination, arrangement, and construction of the various parts, all as more fully hereinafter described, whereby the device is simplified in construction and materially cheapened in cost of manufacture, besides being rendered more durable and easier of operation.
In the drawings, Figure l is a perspective view of a three-bellows pneumatic motor containing my invention. Fig. 2 is a vertical section through the valve-casing centrally through one of the valves. Fig. 3 is a horizontal section on line a; a; of Fig. 2.
A represents-three bellows, which in the terms employed in the art of piano-players and other mechanical musical instruments are calledpneumatics. The movable boards Bof these bellows are hinged at one end and at the other end are connected by connectingrods 0 with cracks D upon a crank-shaft E, which isjournaled in brackets F. The cranks are arranged at thirds, so that when the bellows are operated each one of them will give a successive impulse to the shaft, and therefore give a continuous rotation thereto in the well-known manner of constructing such motors for mechanical musical instruments. The valve-case for these bellows I preferably secure, as shown, to the stationary boards of the bellows, which are arranged side by side, and I preferably make it of two blocks G and H. The block G, I form with a longitudinal groove I in its upper face and the block II secured on top of the block I, so as to close or'form the top of the groove I. This groove when closed at the top by the block II forms a common exhaust or pressure chamber for all the pneumatics of the motor. In the block H, I form a series of lateral chambers J, one for each bellows of the motor. Through the block H and through the chambers J therein I bore a ho1e,which leads from the top of the block II into the chamber 1 of the block G, and I line this hole with a tubular lining K, as plainly shown in Fig. 2. The lining K, I provide at a point in the chambers J with a port or portsL.
M is a piston fitting in the tube K and adapted to be moved above and below the ports L by suitable connection with the crankshaft. In this case. I show the piston connected with the crank-shaft through the medium of the connecting-rods O by means of the connecting-rods O, which are connected to the piston-rods P, in turn connected to the piston, and work through guide-apertures in the guide-bar Q, which is secured in this case upon the blocks R upon top of the blocks H and by suitable screws S with the rear wall of the pneumatics.
The particular motor which I have illustrated is adapted for operation either with compressed air or with an exhaust apparatus. If an exhaust apparatus like an eX- haust-bellows is used, the air is exhausted from the chamber I, and the piston M in one of the bellows being above the ports L will connect that bellows with the common exhaust-chamber I, collapsing the bellows and starting the shaft to rotate. That piston will then be caused to move downward, first closing the ports L, and then passing below those ports, so as to open the ports to the atmosphere through the upper face of the block II by way of the tube K, thereby permitting the air at atmospheric pressure to rush in and expand the bellows. These operations being repeated in each one of the three bellows successively, a continuous rotation will be imparted to the shaft E,
It will be seen that this is a very economical form of motor and a very economical form of valve-casing to make, as the chamber I can be routed out of the top of the block G, while the chambers J can be readily made by machinery, the tube K being simply forced into the bore which is made through the block H, the whole being secured together by glue, screws, or otherwise. By having the tube K a comparatively large one and the ports L of large area I get a very rapid action of the exhaust and air inlet with but little of the sucking noise, which has been one of the difficulties of some other motors, and it is well known each tube, and a piston in each tube actuated by the motor-pneumatic, and adapted to be moved beyond said ports each way.
2. A valve-casing for pneumatic motors comprising two blocks secured together, the lower block having a longitudinal groove in its edge and the upper block secured thereto covering the groove to form a passage lead- JOSEPH COURVILLE.
