WATER- MOTOR.

SPIHJCIFICATION forming part of Letters Patent No. 267,672, dated November 21, 1882.

Application filed March l0, 1882-. (No model.) i

[o all whom it may concern:

Be it known that I, JOHN G'OATES, a citizen of the United States, residing at Erie, in the county ot' Eric and State of Pennsylvanimlhave invented new and useful Improvements in Water-Motors; andl do hereby declare that the following is a full, clear, and exact description thereof, reference being had to 'the accompanying drawings and the letters or figures of' reference markedthereon.

My invention relates to the construction of water-motors, and particularly to that class of water-motors known as piston-r'notors.7

The particular object ot' my invention is to. construct a water-motor which is peculiarly adapted to operate the bellows of organs. My device, however, is not restricted in its use to the purpose named, butmay be used as a motor for general purposes.

The especial nature ot my improvements and the scope ot' my invention will fully appearinthei'ollowinggeneraldescription thereof and the subjoined claims.

My device is illustrated in the accompanying drawings, as follows: Y

Figure l is a longitudinal vertical section, with some parts in elevationthe line of section in this ligure being theline z z in Figs. 2 and 3. Fig. 2 is a transverse vert-ical section on the line a; a: in Fig. l, the parts beyond being in elevation. Fig. is a plan view ot' thed under side ot' the cover of the bed A. Fig. 4 is a detail ot' construction. Fig. 2 also shows the connnection ot' the inlet-valves of the snpply-pipe with the organ.

The various parts are indicated by letters of reference, as follows:

A is the base of the machine, and contains the valves and valve-gears within its chambers A. B is thecylinder; B',the piston-chamber; B2., the piston 5 B3, the 4piston-rod. U is the valve-`chamber5 U,thevalve; l 2 3 4, the passages in the valve; cl d', the passages from the valve-chamber to the passages. leading to the piston-chamber; D, the supplyp`assage; c c, the exhaust-passages; I? \l, the passage to the upper end of the cylinder; P2, the passage to the loner end ot' the cylinder. p p are the ports. g' is a tappe'L-arm ou the pistonrod. g g are adjustable tappet-collars on the valve-rod. G2 is the valve-rod or tappet-rod.

G is the valve-crank G, the valve which regulates the movement of the piston in the auxiliary cylinder from which theirain valve is moved. E is the saidauxiliary cylinder; e, the piston-stem ofsaid auxiliary cylinder; C2, the crank-arm of the main valve. D' D2 are inlet-valves in the supply-pipe. gan; M, the organ-bellows. L is the winch by which the organist opens the supply-valve D'. K is a cord connecting said valve with said winch. I is a weighted arm regulating said valve D. J isthe Weight on said arm. I and J are similar devices onthe valve D2. K `is a cord connecting the arm l with the b ellows M. F isthe supply-pipe for the cylinder E. H is the valve-chamber of this cylinder, H H, the water ways or passages, and h the exhaust. i

The construction is as follows: The main cylinder, B, sits on the base A in a vertical position. which conveys the water 'to and from the upper port, Q. The lower port, p, is in the top of the base. 0n the under side of the top of the base the castingfi's extended down so as to bring the valve into proper position, and thus are formed the chambers P' 13R-which are in fact parts of thc passages to the ports 1o and p. The ina-in valve U is an oscillating plugvalve. lt is mounted at one end on its stem as a journal and at the other end on a pivotpointed adjustingscrew, N, which holds it so as not to bind or wedge in its chamber. It is provided with Ds or pas'sagcs l 2 3 4, ot'which l is the supply D, 2 and 3 are exhaust 4. is the back chamber, and is connected with the supply D by a veilt or passage, V, which allows the water to lill the chamber 4 and keep the valve balanced. C is the main valve chamber or chest, and has openings c c for the exhaust, and d d for connecting with the passages P, P', and P2. into the supply passage or chamber D. llhe valve is moved by an arm or lever, C2. The water exhausted" from the valve-chamber enters the chamber Al in the base A, and finally passes ofi through a pipe, a.. By this arrangement the exhaust is very i'ree and no backpressure will occur. Y

The mechanism for moving the main valve is as follows: An auxiliary motor, E, is at- It is provided with a passage, P,

7s, andv O is the or- It also has an opening -tached to the cover of the base A, and lies at as this engine is operated the main valve is oscillated. The time of movement of the auxiliary motor is regulated by the position of the collars g g on the tappet-rod, and as they can be adjusted as desired the length of stroke of the main piston can be regulated. rlhe object of the auxiliary motor is to secure a full movement of the valve by a tappet device and prevent the valve C from stopping while its faces are passing the ports of the valve-chainber, which it would do if the tappet-rod were connected directly or by levers with the arm C2, for the reason that the water has no expansive power, and as soon as the pressure is stopped, (as it is the instant the faces of the valve get opposite the ports,) the source of power-wiz., the head ot' water-v-is cut oft' from action upon the piston and the motor stops. It' the motor were operating machinery which would run past the point by vmomentum it would be able to pass its faces over the ports; but in an organ-blower this could not well occur, and the advantage of this construction is that the main pistonrod B3 changes its movement from one direction to the other without any perceptible jar or jerk.

rlhe mechanism for regulating the supply of water to the motor is as follows: D' and D2 are throttles in` the supply-pipe, one of which is connected by a cord with the winch L, or some other suitable device on the organ, which is accessible to the organist, the other throttle is connected to the organ-bellows. These throttles are weigh ted similar to a safety-valve on av boiler, and unless held open by the cords will be keptshutbytheweight. Thethrottleconnected with the bellows is so connected therewith that when the bellows are collapsed the throttle will be open, and when the bellows are iniiated the throttle will be closed. The other throttle is opened or closed at will by the organist. The resultot` this construction is that when the organist opens the throttle D' the motor will be set in motion, and it' the bellows get pumped full the other throttle, D2, will be closed and stop the motor, thus avoiding all danger of bursting the bellows in case the organist fails to stop the motor when he stops playing upon the organ, or when the consumption ot' air is less than the supply. When my motor is used for running a gas-machine the second throttle can be connected with the gasolneter and serve as a governor, the same as in the present instance.

In Fig. 4 a detail of construction is shown.

It consists ot' a friction-bearing upon the tappet-rod to keep itfrom falling of its own weight. The bearing is pressed against the rod by a spring, the tension of which is regulated by a screw.

The object in placing the valve at one end ot' the cylinder ot' the main motor is to get as speedy an exhaust as possible by utilizing the weight of the water. This position of the valve would be of no special advantage it the cylinder was horizontal. Another advantage of this v ary motor for opera-ting said valve, also ar.

ranged within said chamber, and, finally, a valve-gear for operating the valve of said sec ondary motor from the movements of the main motor.

`2. In a water-motor, the combination, substantially as shown, ofthe following elements: the hollow base A, with discharge a, the cylinder B, with ports connecting with said hollow base, a valve for supplying water to and exhausting it from said cylinder, placed within said base, a secondary motor arranged within said base, and connected with said valve by the rod e, and having a valve, G, with arm G', and, finally, the tappet-rod G2 and tappetarm g'.

3. In a water-motor, the valve C', with D- chambers l 2 3 4, and vent or passage V, substantially as and for the purposes set forth.

4. rlhe combination, with the supply-pipe ot' a watermotor, ot' two throttles or shut-off valves, D' D2, having cords for the purpose set forth, of mechanism which, when valve D' is opened, opens and closes throttle D2, for the purpose set forth.

5. The combination, with the supply-pipe ot' a water-motor, ot' two throttles or shut-ofil valves, D' D2, the first operated by hand and the second by the action ot' the mechanism to los IIO

which it is attached, as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 4th day of March, 1882.

JOHN GOATES.
