MEANS FOR TRANSMITTING POWER FROM STEAM-ENGINES OR OTHER MOTORS.

SPECIFICATION forming part of Letters Patent No, 251,593, dated December 27, 1881.

. Application filed March 23, 1881. (No model.)

To all whom tt may concern Be it known that I, HENRY A. JAMiEsoN, of Brooklyn, in the county of Kings and State ot' New York, 4have invented certain new and useful Improvements in Means for Transmittin g Power from Steam-Engines or other Motors, ol' which the following is a specitication.

Myinventiou relates to mechanism for transmitting the power ot` a steam-engine or other motor to any distant point-as, for instance, from the top to the bottom otl a mine-shaft for workingpumps to free the mine of water-without the use of rods, shaftiug, belts, gearing, or other positive connections.

The object of the invention is to enable watertor other incompressible liquid to be practically used as a means of transmitting power, the water or liquid being forced alternately through pipes by the reciprocation of the piston or diaphragm of a steam-engine or other motor, and actuating a piston or diaphragm in a cylinder or chamber at a distant point.

The invention consists in the combination, with two cylinders or chambers and pistons or diaphragms therein, of two pipes for establishing a free communication from the two ends of one cylinder or chamber to the two ends ofthe other cylinder or chamber, a steam-engine or other motorfor reciprocating' one of said pistons or diaphragrns, and pass-over valves in the cylinder or chamber of the piston or diaphragm so actuated as to permit the liquid to pass from one end thereof` to the other end, as

hereinafter fully described. When the two cylinders or chambers and their connecting-pipesare lled with water or other liquid the movement of one piston or diaphragm will force the water infront of it through one of the connecting-pipes, and thus produce a simultaneous movement ofthe other piston ordiaphragm, and the powerof the actuating piston or diaphragm, when moved in either direction, is transmitted Vthrough a water or liquid column and prod uces-l a corresponding movement ofthe other piston or diaphragm, which may operate a pump or perform other useful work. Whenever the piston or diaphragm which is actuated by the liquid completesits stroke the continued motion of the other piston or diaphragm will cause the liquid to pass through one or the other of said pass-over valves and permit the last-said piston or diaphragm to complete its stroke, thus providing for the working of the two pistons or diaphragme simultaneously after the completion of lthe first stroke, even though they may not both be at the end ot their stroke when started.

The invention also consists in the combination, with the foregoing, of a supply-reservoir connected with one of the cylinders or chambers or with the connecting-pipes, and serving to compensate for any leakage by keeping the two cylinders or chambers and their connectin g-pipes completely tilled with water or liquid.

In the accompanying drawings, Figure 1 represents a longitudinal elevation and partial section ot' a pumping apparatus embodying my invention and arranged in a mine-shaft: and Fig. 2 represents a transverse section 'upon the dotted linea-, Fig. l.

Similar letters of reference designate correspondinp,` parts in both iigures.

A designates a cylinder, which may bc arranged in any suitable place-as, for instance, immediately over the mouth of a mine-shaft, B; and O designates a piston, which is reciprocated by a direct-actin g engine, D, of ordinary or any other suitable construction, or by any other mechanism adapted to the situation. The cylinder A is very similar to an ordinary pump-cylinder, but is not provided with any suction or discharge valves.

E designates a cylinder, whichis arranged at the bottom of the shaft B, or in any other situation where it is not desirable to place the engine D itself. Upon opposite ends of the cylinder E are single-acting pum p-cylinders F, which openinto the cylinderE and are closed at their outer ends, as clearly shown. In the cylinder E is a piston, Gr, to which are connected two pump-plungers, H, and the two plungers and piston may be provided with suitablelleather or other packings and be all connected by a bolt, a., passing through them and having a uut, b, at each end. In the ends ofthe cylinders F may be placed rubber cushions b for the nuts b to strike against. Below the cylinder E is a suction-chamber, I, into- Which water is drawn through a suction-pipe, c, and above it is a discharge-chamber, J, from which water is discharged through a standpipe, d, which may lead to the top of the shaft` f IOO l. Water is drawn from the suction-chamber through valves e into the pump-cylinders F, nd from said pump-cylinders is discharged hrough other valves, j', into the dischargehamber J; but none of the water enters the ylinder E.

The combination, with the cylinder E and `iston G, of the pump-cylinders F and plun- 'ers H, I do not here claim, and in lieuof be- 1g employed in pumping, lthe cylinderl't` and listen G might be employed to do other useul work.

K K designate two pipes which establish .ninterrupted communication between the two nds of the cylinderA and the cylinder E, and hese pipes may extend any reasonable distance nd through circuitous passages where power ould not be practically transmitted by rods r other mechanical devices. It' the two cylnders A and E are entirely iilled with water r other liquid, it will be readily understood hat when the piston G is moving in the di! ection indicated by the arrow the water or liqlid will be forced down the pipe K, moving he piston G and the pump-plunger-H in the Lirection indicated by the arrow, and producing ,n upward current in the pipe K', to lill the `ylinder A, behind or on the right ot' the pis-y on C. NVhen the piston C is moved toward he right lthe water will be forced downward n the pipe K and upward in the pipe K, movng the piston G and its attached plungers H oward the left. Thus it will be understood hat in whichever direction the piston G is noved the pressure exerted by it is transmited through the columns of water in the pipes i K, andthe piston G is moved simultaneousyin the opposite direction. By inserting a ining in the cylinder D its power would be ncreased, but the piston E would not then per- 'orm its whole stroke.

It is desirable that the two pistons G and G `li'ould both move in unison, or commence their ytroke together, and yet if, when the apparatus s started, the piston C commences its stroke vhile the piston G is at the middle of its stroke, he piston C could only move until the piston Sr reached the end of its stroke, and the appalatus would be stopped. To prevent this, and inable both pistons to come to a common startng-point, no matter at what point in their itroke they are started, I connect the two ends f the cylinder A by two passages, g, oneot' vhich is shown in section, and the flow ofliquid 'rom the ends of the cylinder through the pas- ;ages is controlled by pass-over valves h h', v'hich are weighted or loaded, so that during :he ordinary working of the apparatus theyA will not open. 1f we suppose that at the first itarting of the apparatus the piston C starts `'rom the position shown in Fig. l to move toward the right, while the piston G starts at )alf-stroke, thepiston O, as soon as the piston 3i ,reaches the end of its cylinder, will, create sufficient pressure to open the valve h, and thus )ermit the passage of water around the piston C to the left-hand end of the cylinder A, and allow said piston to complete its stroke. The two pistons C and G will then commence their second stroke from the ends of their respective cylinders and terminate their strokes together.

It is intended to keep the cylinders A and E and the pipes K K always full of water; but as there will necessarily be some slight loss by leakage, I provide a reservoir, L, above the cylinder A, which communicates with the passages G by pipes i, in which are check-val ves i', which will open to permit water or other liquid to pass from the reservoir L to the cylinder A, but will not permit liquid to pass from said cylinder to said reservoir, thus compensating for any leakage.

In deep mines the rods for transmitting motion to pumps in the mine from actuating mechanism at the surface are often of great length and weight and take up room in the shaft which cannot well be spared. By my invention such ponderous connectionsare dispensed with-and the power transmitted through the water-columns in an economical and effective manner.

1f desirable, diaphraglns might be substituted forthepistons G G and the chambers in which the diaphragms'are arranged connected by the pipes K K.`

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination, with two liquid cylinders or chambers and -pistons or diaphragms therein, of two pipes for establishing free communication from the two ends of one cylinder or chamber to the two ends of the other cylinder or chamber, a motor for reciprocating one piston or diaphragm, and a pump or pumps actuated by the other piston or diaphragm, substantially as and for the purpose specified.

2. The combination, with two liquid cylinders or chambers, the two ends of one ot'which are connected by passages controlled by loaded pass-over valves, and pistons or diaphragms in said cylinders or chambers, of pipes establishing a free communication from the two ends of one cylinder or chamber to the two ends ot' the other cylinder or chamber, and a motor for reciprocating one piston or diaphragm,substantially as and for the purpose specited.

3. The combination, with two liquid cylinders Aor chambers and two pistons or diaphragms therein, of pipes for establishing free communication from the two ends of one cylinder or chamber to the two ends of the other cylinder or chamber, a liquid-supply reservoir, and a valve or valves which permit the passage of liquid from said reservoir `to one of said cylinders or chambers, and a motor for reciprocating one ot' said pistons or diaphragms, substantially as and for the purpose specified.
