Specification forming part of Letters Patent No. 184,95 1, dated December 5, 1876; application filed January 22, 1876.
steam-cylinder. It is provided with a piston,
O, and rod G. Externally it is fitted as a piston to the cylinder B. A is provided with a hollow piston-rod, through which the rod G passes. A can also have a piston-rod pass out ofthe opposite head of cylinder B, either or both of which can be used for the purposes hereafter described.
The cylinder-piston A is provided with two longitudinal cuts or grooves in its outer surface. They are each a. trifle longer than the stroke of the piston, and communicate with ports of cylinder A only at one end of grooves, the other groove communicating with the opposite port. These grooves are the means of supply and exhaust for cylinder A. Midway in cylinder B are orifices connecting with these grooves. There are passages connecting with these orifices, and with opposite ports of cylinder B, also with source" of supply through the four-w'ay valve-boxes. There are two of these valve-boxes. connected, so that they balance. Their movements are simultaneous and in opposite directions-that is, as one set of ports are closed, the corresponding ones are opened. These valves are actuated by mechanical means.
The cylinder B is provided with an exhaust independent of those through the four-way valve box. This independent exhaust is either stopped off and opened by the piston A or with suitable valves and gear.
In this system it is intended to work oruse steam or any elastic fluid, full force or pressure, in the cylinder A and against the piston G. Then its property of expansion is utilized in B against the piston A in the first part of the return stroke.
In this system the expansive property of The valves arethe fluid is first used to overcome the resistance; then the direct push or initial force completes the stroke or semi-revolution of the crank.
When A has performed the functions of piston for cylinder B, and has moved its full throw, it is in that position held rigid while piston G is moving through its cylinder. A is then released and again performs its duty as piston. Thus itsfunetions alternate. A is held in position and released by suitable mechanical means attached to its piston rod or rods, or to the cylinder-piston A direct.
This system of cylinder-pistons can be increased, if practicable. Necessary packing, means of lubricating, pet-cocks, &c., are provided.
Its operations are as follows: Suppose A, on one side of C, to be charged with the fluid of initial pressure. As the valves are actuated so as to bring a similar press'ure on the opposite end of 0, communication with cylinder B and cylinder A will be opened, and expansion will move the piston A. O and rod G will be carried with it. When piston A has performed its travel an exhaustport is opened, letting the expansive fluid that moved it escape. At this point A is held firm, as already described. As the steam resistance is now removed from 0, this piston will be moved to the opposite end of cylinder A, thus completing the semi-revolution of the crank. The valves are now changed, the piston A is released, and a similar action in the opposite direction is produced, which becomes alternate.
What lclaim, and wish to secure by Let-.
ters Patent, is
1. In a movement that is actuated by the mechanical properties of fluids, the combination of one cylinder and two pistonsviz., the cylinder-piston A and piston C, so that 0 moves with A when A acts as piston, and through A when A performs the function of cylinder, substantially as and for the purposes set forth. v
2. The combining of cylinder B, cylinderpiston A, piston G, and rod G, so arranged that the piston-rod G will be produced a dis tance equal to the sum of the travel of all the pistons in the system, substantially as described.
Th wfQ m a v $0. arranged cornb'iliatibii witli cylinder-piston A 5nd cylinder B, to operate substantially as described.
4. The afrangement, in a system of cylin-' ders and pistgl s, pf the g egtps, substantially as described, fbiactuating dne pisto'n only at a time, each piston, after it is moved its throw,
me p nainin g stationary as to its cylinder "until all the pistons reach the end of their strokes.
