FLUID- MoTlvE-POWER PUMP.

SPECIFICATION forming part of Letters Patent No.f761,366, dated May 31, 1904.

Application filed September 5, 1903. Serial No. 172,158. (No model.)

To all whom, t may concern,.- y

Spring, in the county of VVashington and State of Virginia, have invented a new and useful Fluid-Motive-Power Pump, of which the fol-l lowing is a specification. This invention relates to improvements in fluid-motive-power pumps. I y

The principal object of the invention is to ,construct a pump in which the pressure or head of one body of water may be employed for ,the pumping of a portion of the same or of an entirely diii'erent body of water to any desired distance and in this connection toso arrange the ram as to entirely separate the two bodies of water or other liquid, so that there will be no danger of interminglingof the two,

especially where a large body of compara tively impure water is used for the pumping of spring or other water to a house or bar for drinking or like purposes.

A further object of the invention is 'to provide a novel form of pump in which positive means are employed for opening and closing the controlling-valve. 1 A still further object ofthe invention is to provide a hydraulic pump with a novel form of inlet-valve so arranged with respect tothe current of incoming water that the pressure or head of the water cannot interfere with the opening or closing movement of the valve. I A still vfurther object of the invention is to provide a novel form of valve and valve-actuating mechanism in which the escape-valveV is yieldably connected to the .piston that is operated by the pressure'of the water, the

parts being so arranged that closing movement ofL the valve will be opposed by conperior area of the latter finally causinga quickopenin g movement of said valve after the exertion of a predetermined strain or force on thel vention consists in the novel construction and v arrangement of parts hereinafter described,

entrance port.

K f illustrated in the accompanying drawings, and Be it known that I, HENRYT. FARNsWoR'rII, a citizen of the United States,residing at Grladev particularly pointed out in the' appended claims, it being understood that various changes in the form, .porportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of tlie`invention.

In the accompanying drawings, Figure lis a longitudinal sectional elevation of a hydraulic pump constructed in accordance with7 the invention. lower portion ofthe same, showing the partsT Fig. 2 is a similar view of the indifferent positions. Fig. 3 is a sectional plan view of the device approximately on the line 3 3 of lFig. l. Fig. 4 isa detail perspective view of the inlet and exhaust valves. Fig. 5 is a view similar to Fig. 1, illustratinga slight modification of the invention.4 v Similar numerals of reference are employed tov indicatecorresponding parts throughout v Y the severalflgure's of the drawings.

In the drawings, l represents a `water-chamber or slulce-boX, preferably rectangular 1n form and provided at one end with an inlet 2 and at the opposite end with an outlet 3. The inlet end is rounded and provided with a threaded opening, into which the inlet-pipe may be secured. while between the inlet end and the water-chamber proper is a dependent partition 5, thatoccupies the upper half of the space and leaves a substantially rectangular port between the lower portion of the entrance-pipe and the water-box for the passage of the Water. The inner face of this partition is preferably rounded Lon a line struck from the center of a pin orshaft 6, which may bein the form of a bolt, and this pin carries a lever 7 at the outer end of which is a valve 8, the outer surfaceV of the valve being concentric with the trawise movement of the piston, and the sun' axis of the pinand adapted to fit snugly against the curved face of the partition 5, so that it may act freely in closing or opening thewaterthis valve, the thrust-'line of the water will be directed to the lcenter of rotation of the valve andthe water cannot to any material extent impede the free movement of said valve.

' The outlet 3 is somewhat contracted in area, having inclined walls 9 and 9', which gradu- Owing to the curved face ofv ally converge inward from the outlet end t`o form a substantially rectangularport in an inclined wall 10. This port is closed by a valve 12, carried by an arm 13 of the lever 7, and the face of the valve is provided with a covering 14, formed of leather or some similar material. The two valves 8 and 12 are so arranged with respect to each other that when one is open the other will be closed, and the inclination of the valve 12 is such that the water will act to better advantage in keeping the valve closed than if said valve were arranged in a direct vertical line.

Secured to the casing and water-chamber is a cylinder 16, the upper end of which has a threaded boss 17 for the reception of a smaller cylinder 18, the latter having internal threads adapted to theboss. The upper end of the cylinder 18 terminates in a T-shaped head, and to one branch of the T is connected an inlet-pipe l 19, having an upwardly-opening check-valve vpreferably formed of Aspring metal.

20, while connected to thev opposite branch of the T is an outlet-pipe 21, having an upwardlyopening check-valve 22. p

In the cylinder 16 is arranged a piston 24, the periphery of which is curved for the reception of a ring 25, formed of leather or other packing material, and a split ring 26, The split ring serves to maintain the packing-ring in the full out position in contact with the outer wall of the cylinder and will to some extent automatically compensate for wear of the packing-ring. The packing-rings are held in place by a metallic ring 27, bolted or secured in like manner to the head of the piston.

The piston 24 is provided with a hollow stem 30, the upper end of which has a threaded connection with a piston-rod 31, that extends up through an opening of suitable diameter formed in the top of the cylinder 16 and at its extreme upper end has athreaded connection with a small plunger'or piston 32, disposed within the cylinder 18. The construction of the plunger may be altered to accommodate varying conditions; but I have found .that a preferred form of piston consists in providing the rod with a ring 33, that rests onV a shoulder 34 near the upper end of the piston-rod, and then placing on thethreaded end of the rod a main piston-body 35 of approximately the same character as the larger piston already described. i

The lower end of the piston-rod is provided with a second set of threads to which is secured a spring sleeve or casing 36, carrying a coiled tension-spring 37, the upper end of which is secured to the'upper portion of the sleeve or casing, while the lower end of said spring is connected to the valve-carrying arm 13 at apoint intermediate of its length.i

In the operation of the device, the parts being in the position shown in Fig. 1, water is allowed to low through the open inlet-port and maintains the outlet-valve 12 closed. The

closed and at the same time to elevate the piston. Owing to the superior area of the 1 latter, the spring will be gradually placed under increased tension untilit overcomes the pressure of the water on the valve, and the valve will open suddenly, allowing the water within the cylinder and water-chamber to flow freely through the discharge-pipe. The openingA movement of the valve 12 has caused a corresponding closing movement oi' the valve 8, so that no water can enter the chamber 1 until the piston in traveling downward decreases the length of the spring and by gradually compressing the same forces the valve 12 to closed position and at the same time opens the inlet-valve. rIhe water again enters through the inlet-port, and the same operation is completed. The uppercylinder 18 and itspiston act as a suction and force pump, and thewater pumped through pipe 21 to the point of consumption may be either a portion that actuates the ram or a distinct body of water, so that water from a spring or other minimum source of supply may be pumped without waste to ahouse or other point by means of a running stream of impure water.

The: construction may be slightly modified in the manner illustrated lin Fig. 5 by placing the spring at a point wholly above the piston. In this figure the corresponding parts bear reference-numerals similar to those in Fig. 1. A spring 37 is arranged in a casing 36', having one end secured to the upper portion of the piston 24 and its upper end connected to the plunger of the pumping-cylinder. The lever 13 is connected to a rod 40, extending up through the compression-spring 37 the upper end of this rod is an enlarged collar or flange 41, with which the upper end of the spring comes into contact when the piston has been raised Afora part of its stroke. On npward movement of the piston the spring is compressed and finally overcomes the resistance olfered by the valve 12. This construction is in some respects preferable to that illustrated in Fig'. l, inasmuch as there is no waste of water and the spring is more eifectually protected.

The spring-casing 36 is provided with an opening 42 to permit the drainage of any water which may accumulate in the upper portion of the main cylinder.

Having thus described the invention, what is claimed is- 1. In combination, a casing having inlet and discharge ports, a pivotally-mounted inletvalve having its seating-face arranged on a Atl vpressure, and a yieldable connection between said piston and the valves.

curved -linel concentric with the pivotal axis of the valve, a discharge-valve connected to and movable with the inlet-valve, a piston arranged within the casing and exposed to water- 2.
