APPARATUS FOR RAISING WATER.

SPECIFICATION forming part of Letters Patent No. 641,251, dated January 9, 1900.

Application filed August 18, 1898. Serial No. 688,921. (No model.)

To all whom it may concern:

Be it known that I,'LELL I-I. WOOLLEY, a citizen of the United States of America, residing in the city of Oakland, in the county of Alameda and State of Oalfornia, have invented certain new and useful Improvements in Apparatus for Raising Water, of which the following is a specification.

My invention relates to improvements made in apparatus for pumping or raising water from a lower to a higher level through the medium of steam-pressure or other gaseous medium supplying the required degree of pressure acting upon the surface ofthe water within a pipe or chamber; and the said improvements consist in certain novel construction and combination of parts having for their object the production of a simple and rapidly-operating apparatus for raising water, as hereinafter described and claimed. 7

The following description explains at length the nature of my saidinvention and the manner in which I have constructed, produced, and carried out the same, reference being had to the drawings that accompany and form part of this specification.

Figure 1 of the drawings is a side elevation, principally in longitudinal section, of an apparatus constructed in accordance with my invention. Fig. 2 is afront view of the steamchest. Fig. 3 is a top view with the cover of the chest removed to expose the valve. Fig. 4 is an elevation of the apparatus, taken from the front or right-hand side of Fig. 1, one of the pressure cylinders or chambers being shown in section. Fig. 5 is a top view of the two cylinders and the discharge-pipe and con nections.

A A indicate two cylindrical pressurechambers set in upright position side by side, and B an inlet-pipe of smaller diameter lead ing from the bottom of each chamber downward into the Well or body of water and provided with an u pwardl y-actin g valve 0 in the lower end.

D is a discharge-pipe connected to an outlet d in the pipe B above the foot-valve O and leading from that connection upward to the required point of discharge above the pressure-chamber. The discharge-pipe from the inlet-pipe B of one chamber is connected into the discharge-pipeD of the other inlet-pipe B, and from that point of connection 01 a single pipe D is carried upward to the tank or other place where the water is to be discharged.

A check-valve E of usual construction is placed in each pipe D between the inlet-pipe B and the point of connection between the two pipes D D.

F-is a float fitted loosely in each pressure chamber and of less length than the chamber. This float is best made of a wooden block conforming in shape to the chamber and presenting a flat head or top. G is a rod fixed in that end and extending vertically upward through the head of the chamber A, a stuffing-box a being provided in the center of that head through which the rod is fitted to work easily.

L is a steam-pipe connected to an aperture h in the head of the pressure-chamber and leading from that part to a steam-chest H, to

which such pipe is connected at it below the floor or bottom of the valve-chamber H I is a slide-valve of the usual construction controlling theinlet-ports l 2 and the exhaustports 3 4 in the valve-chamber.

K is a rock-shaft having a tappet K engaging the slide-Valve and on the end outside the chest an arm P, by the movements of which the valve is thrown to one side or the other.

In the lower part of the steam-chest are the steam-passagesm m to which the two steampipes L L are connected, and also the separate exhaust-steam passages 17 p, from which the exhaust-steam pipes or outlets M M are carried through the ends of the chest.

The inlet-ports 1 2 are arranged on opposite sides of the abutment or partition separating one steam-passage m from the other or other source of supply, and by the throw of the Valve the steain is admitted alternately through the ports 1 and 2 first into one chamber A, above the float, and then into the other chamber A.

The movements of the valve are effected by the downward movements of the floats F through the medium of the rods G on each float, a tappet G on the rod, and a lever S, attached at one end to the arm P of the rockshaft and forked on the opposite end to embrace the rod, as shown in Fig. 4E.

The levers are crossed and are pivoted at S S on a suitable fixed support- T.

As thus constructed the operation of the apparatus is as follows: When the pipes B B are immersed in the well or body of water to a sufficient depth to bring the greater portion of the chamber A below the level of the water, steam is admitted to the valve-chamher and the valve is set in motion. According to the position assumed by the valve steam is admitted to one or the other of the chambers A, forcing down the float and acting against the surface of the water contained in the chamber and in the inlet-pipe above the foot-valve with sufficient pressure to force the water into the discharge-pipe and beyond the check-valve in that pipe. As the float reaches the limit of its downward movement the tappet G2 on the floatrod strikes and draws down with it the outer end of the lever, thereby throwing up the opposite end, that is connected to the arm on the rock-shaft, and through that movement throwing the valve over to the opposite side. By such movement the inlet-ports are set to admit live steam to the other pressure-chamber, While the exhaust-ports are opened and set to connect the steam-conducting passage of the first chamber with the exhaust-pipe and outlet provided for it in the side of the steam-chest. By this means the steam-pressure is removed from one float, and it then rises by virtue of its own buoyancy and the upward pressure of the water entering the pipe B as the float in the other chamber is forced down by theincoming steam admitted through the valve and the conducting-pipe. The tappets G2 are adjustable on the rods G for the purpose of regulating their time of contact with the valve-actuating levers.

In place of steam compressed air or other gases supplying the required degrees of pressure may be used as the medium to work upon the floats.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The herein-described apparatus for raisin g water comprising pressure-chambers A A, suction-pipes B B having foot-valves O,a common discharge-pipe D, connections between the suction-pipe and the discharge-pipe,checkvalves in said connections, a steam-chest in which there are separate compartments for each pressure-chamber having ports and passages for admitting steam to and exhausting it from the pressure-chamber,a slide-valve controlling the two sets of ports and passages, floats F F in the pressure-chambers, float-rods G G, and the means whereby the slide-valve is operated by the rising and falling move ments of the floats consisting of the rockshaft arm fixed thereon, levers attached to said arm and the tappets on the float-rods adapted to engage the levers, substantially as described for operation as set forth.

2. In-an apparatus of the character herein described, the combination with a pair of pressure chambers having inlet pipes and discharge-pipes provided with suitable valves to prevent the return flow of the water; of the steam-chest having a set of inlet ports and passages and a set of exhaust ports and passages for each pressure-chamber, a valve adapted to control said ports and passagesin alternate manner through the medium of the float-rod of the chamber, a tappet on therod, a rock-shat t adapted to move the valve and a pivoted leverconnected to the rock-shaft and set with relation to the tappet of the float-rod, as described for operation as set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
