4 To all whom it may concern,.-

Beit known that'we, JOSEPH NEWTON FUL- TON and LUTHER D. FULTON, citizens of the United States, residing at Titusville, in the Vania, have invented certain new and useful Improvements in Apparatus for Transmitting Power, of which the following is a specication.

This invention relates to new and useful improvements in apparatus for transmitting power, and is more especially adapted for use in operating series lof pumps. Its primary object is to provide an apparatus of simple construction which dispenses withall movable levers, rods, dac., in transmitting power 'and which permits of the direct application of power from a central station to one or more pumps or other devices to be operated.

A further object is to provide an apparatus whereby the devices to be operated may be moved in unison without loss of motion.

Aof the main cylinder is adapted to be operated by a suitable motor, and the pistons of the remaining cylindersare secured directly to the pumps or other devices to be operated.

i The pipes and cylinders are completelyfllled with a non-compressible liuid adapted to be moved back and forth within the supply and return pipes and the cylinders by the movement of the main piston, said pipes'being provided with suitable valves and cocks, whereby circulation within one or more of the cylinders may be cut off and leakage of water from one side to the other of the pistons within the cylinders be automatically compensated for.

The invention also consists in the further novel constructions andcombinations of parts hereinafter more fully described and claimed, and illustrated in the accompanying draw'- ings, showing the preferred form of our invention, and in which- Figure lis a diagrammatical view of the apparatus, showing the cylinders in section. Fig. 2 is an elevation of a portion of the apparatus, showingH its application to a .pumpg and Fig. 3 is a detail view of a modified -arrangement of pipes.

Referring to said figures by numerals of ref- 5 5' erenoe,1is a main cylinder having gages, as 2, connected thereto by means of pipes 3 and having mounted therein a piston 4, the rod 5 of which may be secured to any suitable motor 6.

of, is a pipe 7, which may for 'convenience 'in describing the apparatus be termed the supply-pipe. A pump, as 8, is connected to this pipe and may be driven in any suitable manner, said pump being adapted to force liquid into pipe 7 as desired. The supply-pipe is arranged adjacent' to each of one or more cylinders 9, each ofwhich is provided with a piston 1Q, having a rod 11, which maybe con- 7o nected in any suitable manner to the device to be'operated thereby. -In Fig. 2 we have shown said rod applied to a pump and connected thereto by means of parallel rods *12,

which run parallel to the cylinder and are 75..

' pipe 16, which connects the cylinder with the 8o supply-pipe 7, and said inlet is supplied with va suitable cock, wherebytthe passage of liquid therethroughmay be readily controlled.l Pipes 17 are arranged between the cylinders and the supply 7 at points between the inlets 85 a 16, and these are supplied with valves', as'/l8,A adapted to open outward when the piston passes the pipes 17 thereof in the event of water escaping from one side'to the other -of the piston, 'thereby compensatingfor the 9o leakage.

In Fig." 3 we have shown a modified form of inlet and valved pipes, which is especially adapted for'use where rthe supply-pipe is remote from the cylinders. supply-pipe is connected with the cylinder by A means of inlets, hereinbefore described. In lieu of extending the valved pipe from the cylinder to the supply, however, we provide a short outlet-pipe-19, communicating by means roo of a connecting-pipe -20 with the inlet.

They supply-pipe is laid adjacent to each of (Shown in dotted lines, Fig. 1.) `Ex- 6o .l tending from this cylinder, near one end there- .l

In said figure the the cylinders 9 and is provided at a point between the inlets of each cylinder with a cock, as 21, for the purpose hereinaftermore fully described. The end of this pipe is connected to a return-pipe 22, which passes directly to that end of main cylinder 1 which is farthest removed from the supply-pipe 7.

A connecting-pipe, as 23, preferably extends from the supply to the return pipes, as shown, and is provided with a branch pipe 24, opening into an air-exhaust chamber 25, having a suitable outlet 26, which maybe closed in any suitable manner. Cocks, as 27 are arranged between the branch pipe 24 and the pipes 7 and 22, respectively.

1n operation all of the valves of the apparatus are opened and a non-compressible liquid, preferably formed of water-and calcium chlorid, is forced into all of the pipes and cylinders by meansnof the pump 8. It will be understood 4that all air within the system will be forced out through the chamber 25, and the expulsion thereof may be accelerated by operating the piston of the main cylinder during the filling of the machine. When the air has been expelled, the cocks 27 and 21 are closed and the piston .4 is driven by means of a motor, as 6. ton moves toward the supply-pipe 7 the water in'the path of said piston will he forced into. the pipe, causing a portion of the contents of the pipe to be forced into one inlet 16 of the cylinders, moving their pistons in unison with the main piston, and the liquid in their paths being forced out through the other 'pipe 16 of the cylinders, causinggas is obvious, a portion of the liquid within the return-pipe to ow into theV main cylinder in the rear of its piston. When the movement of the pistou 4 is reversed, the movement of the current within the pipes and cylinders will be` reversed therewith, and as the liquid used completely iills the system and cannot escape or be compressed it will be readily understood that the pistons of each cylinder will move in harmony with the main pistonr4.

In the event of any leakage which mighta occur phrough the pistons of the cylinders causing the amount of liquid on one side ofthe piston .to be less than the amount required to drive said piston its full stroke the pressure will be eqnalized by the admission of liquid to the side of the piston requiring the same through one of the valves 18. In

other words, should the piston in one of the cylinders 9 reach the vend of its stroke prior to'the completion ofthe stroke of the piston 4 the water which continues to flow into the cylinder in rear of its piston will force open the valve 18 adjacent to said piston, and thus flow past the closed valve 21, arranged within the supply-pipe 7 at a point between the valves 18.

When it is desired to st'op the motion of one of the cylinders without interfering with the operation of the balance of the system, it is merely necessary to open the cock 2,1 of

It is obvious that as the pisthat cylinder, and the liquid will then pass directly through the supply-pipe 7 without entering the cylinder by way of the inlets 16. By opening the cocks 27 all of the cylinders 9 will be placed out of circuit, as' the WaterI will flow directly from one end to the other of the cylinder l.

While we have shown and described this device as being especially adapted for use inl pumping systems, we do not limit ourselves thereto, as the same may-be used forany of numerous purposes forwhich a stationary .engine may be employed, nor do we restrict ourselves to any particular form of motor for driving'the Amain piston 4. The pum-p 8 may be operated by means of the motor 6; but it is preferably driven independently thereof.

Itis our idea to have an air-chamber 25 arranged at one or more points above thebalance of Ythe system. We find that when a system is charged with iuidfrom the pump 8 the air is forced ahead of the same and through the pened cocks 27 i to the airchamber. The small amount `o air which mixes with the water soon finds its way to the air-chamber, discharged. The cocks within the pipes `16 'and 17 are employed for preventing the water from flowing into the cylinders when it is desired to repair them or for any other reason. In the foregoing'description we have shown the preferred form of our invention; but we do not limit ourselves thereto, as we are aware that modifications may be made therein without departing from the spirit or sa'cricing from which it may beV readily ICIO the advantages thereof, and we therefore reserve the right to make such changes and alterations as fairly fall within the scope of our invention.
