FORCE-PUMP AND WATER-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 484,169, dated October 11, 1892.

Application filed April 29, 1891.

To all whom it may concern.-

Be it known that I, MILO LUTHER GATES WHEELER, a citizen of the United States, residing at- North Yakima, in the State of Washington, have invented certain new and useful Improvements in Force-Pumps and Water- Elevators; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in compressed-air water-elevators; and the object in view is to provide simple and efficient means for raising the water from a well, cistern, or other subterranean place by means of the force of compressed air, steam, or other motive fluid.

In this invention I contemplate the provision of means whereby water froma lower level than the place where the air or steam is compressed or generated may be raised without any expenclilure of manual labor, although the latter may be used, if desired; but it is not essential, as provision is made for the automatic inlet and egress of the pressure-fluid and for the like automatic ingress of water to a cylinder and for exit of the Water from the lower levelto the devices which convey the same to a higher level.

By this invention either air or steam may be used as the motive fluid, and in case of steam-power it is only necessary to provide a suitable generator and couple the same to the working cylinder of the hydraulic elevator. When compressed air is to be used as the motive fluid, an air pump or compressor is provided, which may be located very close to its source of power-as, for instance, upon the tower of a windmill close to the sails thereof and thereby avoid the friction and waste of power necessarily present when heavy cumbersome pitmen are used to transmit the powerv from the elevated shaft to the counter-shaftiug at the base of the tower.

The inventionconsists in the combination of devices and novel construction and arrangement of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

My invention is fully illustrated in the ac- Serial No. 390,997. (No model.)

tail detached views of the valve mechanism for the hydraulic cylinder provided for the regulation of supply and exhaust of the compressed motive fluid.

Like letters of reference denote corresponding parts in all the figures of the drawings, referring to which A designates the hydraulic cylinder, adapted to be lowered into a well, cistern, or other deep or shallow place and to be entirely submerged in the water-supply therein. This cylinder A may be of any suitable construction, consisting, preferably, of a cylindrical barrel a, the two heads I) b, and bolts connecting said heads, although this detail construction is not essential, as I may employ short bolts to couple double-flanged barrel and heads together in the manner familiar to those skilled in the art. In the lower part of the barrel of the hydraulic cylinder is provided a water-inlet port 0, through which the water flows into the cylinder, and this portis closed by means of a flap-valve O, which is adapted to open inwardly when the cylinder is free from the influence of the compressed motive fluid adapted to be admitted thereto for forcing out the water therein, whereby this inlet-port valve may be opened by the pressure of surrounding Water to permit the cylinder to be filled to the desired limit by the pressure of the water in which the cylin I der is submerged. A suitable valve-seat maybe secured around this inlet-port, and the seat and valve may be packed in any desirable manner, which,'however, I have not deemed it essential to illustrate, as the same is of the ICO is secured the spouted pipe F, having the goose-neck or spoutf at its extremity, and on this pipe F is secured the collar or supporting-plate F, which is adapted to be secured in any suitable way to the floor of the cistern, well, or other place where the elevator is used. The lower end of the pipe E terminates close to the bottom head of the cylinder A, and the lower end of the pipe F likewise is arranged close to the bottom of the upper inclosure or shell E. g

The upper head of the hydraulic cylinder is made dome-like in form, and itis provided on one side with ahand-hole g, which is closed by a cover G of common construction. This head of the cylinder is shaped or constructed to receive the support or block H of a Valve I, adapted to control the supply and exhaust of the compressed motive fluid adapted to be admitted to the hydraulic cylinderA to expel or elevate the watertherein. This valve-seat H is secured to the upper head by bolts or in any other suitable Way, and the lower side of the valve-seat is provided with a segmental or curved recess h, which constitutes the seat for the valve 1, and the upper side of the valve is curved,as at 2', to adapt the same to be sn ugly fitted in the seat. This valve is of the oscillating variety, adapted to rock or turn back and forth around a fixed axis, which is formed by the shaft, trunnions, or bolt t", on which the valveis rigidly secured. This axial bolt or shaft 2" of the rocking valve has its ends loosely journaled in the lower extremities of adjusting-links J J,'the' upper ends of which pass through fixed guides j, which are rigid with the valve block or support H, and the upper ends of the links are encircled by spiral tension-springs j, which bear against the fixed guidesj, and nutsj which are fitted on the threaded upper ends of the suspending links. These spiral springs serve to normally draw the valve snugly to itsseat in the block or support, and by adjusting the nuts the tension of the springs can be varied to always insure the necessary tight joint between the valve and its support or block to prevent the leakage of the motive fluid between the valve and its support.

Through the fixed support or block H of the valve are provided the inlet and exhaust ports 70 for the compressed air or other motive fluid, said passages being'independent of'each other, and the upper ends of the passages are enlarged and internally screwthreaded to adapt the lower ends of the supply and exhaust pipes K K to be coupled directly to the support orblock H. The lower ends of the passages 70 70 open through the lower side or seat of the valve-block, and with these passages are adaptedto communicate radial passages ZZ, forming the inlet and egress passages through the valve for the compressed air or steam, said inlet and egress passages in the valve terminating at their inner ends in circular enlargements which open through the side or lateral faces of the valve to insure means of the fixed studs 0 0, which are rigid with the valve and project laterally from the same, and these studs are adapted to alternately impinge against the stop-bar 0 which extends across the face of the valve and has its ends secured to the valve-support H, so that the play of the valve is arrested at the desired points to cause the ports therein to properly align with the passages in the support or block H.

To one arm of the valve shaft or bolt is rigidly secured a rock-arm L, to the other end of which is pivoted an endwise-movable floatrod L, that is arranged vertically in the hydraulic cylinder and lies parallel to the wateroutletpipeleadingfromsaidcylinder. Around this float-rod and the exit-pipe is loosely fitted the float M, of any suitable form and construction, and which is free to rise and fall in the hydraulic cylinder with the water therein, and this float acts on the stops m m, which are secured to the float-rod at the upper and lower ends thereof, or at any desired points at. which it is desired to cause the float to open the valve-ports for the ingress and egress of the compressed air, so that the upper stop m is adapted to determine the water'level in the hydraulic cylinder. The stops on the float-rod are in the path of the float, and when the float is lowered with .the Water in the cylinder A the lower stop m is forced down to depress the rod, turn the arm L, and move the valve so that the exhaust-port Z therein will align with the exhaust-passage 7c in the support H to permit the compressed air in the cylinder A to pass into the exhaust-pipe K, which should extend above the surface of the water in the well or cistern in which the cylinder is submerged, and when the water has reached the desired level and the float is released, it impinges against the upper stop on and raises the rodLto turn the arm L and the valve, so that the alignment is broken between the exhaust-passages Z and k in the valve and seat and establish communication between the inlet-passages l the lower stop m and the valve-rod so as to shift the valve I and bring the ports Z 70 into alignment, so that the air in the cylinder can be exhausted or discharged and the valve 0 reopened to again admit water to the cylinder A.

Steam from a suitable boiler or generator may be admitted directly to the cylinder by leading and connecting the pipe K to the steam-dome of said generator; but I may also employ an air-compressor, as shown in Fig. l, to supply compressed air as the motive fluid for raising the water. This compressor has a connected barrel and heads, forming the cylinder P, in which reciprocates the piston P, which is suitably packed, the heads of the air-cylinder being provided with the springcontrolled inlet-valves p 10, adapted to act alternately to admit air to either end of the cylinder on reciprocation of the piston P. This piston has its rod q, passing through a suitable stuffing-box in one head of the cylinder, and said rod operates in a fixed guide q. The piston-rod is reciprocated in any suit-.

able way, either by a pitman (not shown) of a windmill or engine or by a hand or power lever Q; but this is not essential, although it is evident that the air-compressor may be placed on top of the tower of the windmill close to the sails thereof, to avoid the use of heavy cumbersome pitmen, and the pipe K can be led from the compressor to the valvesupport of the hydraulic cylinder.

The air-pump is of the duplex or doubleacting class, and from the opposite heads thereof lead the outlet-pipes a" 4", which each havea check-valve T and said outlet-pipes are connected to a common pipe R, which in turn leads and is coupled to the supply-pipe K for the hydraulic cylinder.

To the supply-pipe R is connected, at a point between the'valve-pipes a" r, a pipe S, having a. relief-valve s, and when the airpump is in operation during the time the airinlet port is closed in the hydraulic cylinder and the exhaust is open therefrom to allow water to fill into the cylinder A the air-pump is relieved from accumulating excessive pressure in the pipes R K by the opening of the relief-valve s in the pipe S.

The operation of my invention will be readily understood by those skilled in the art from the foregoing description, when taken in con nection with the accompanying drawings.

If desired, a signal or call-whistle (not shown) may be attached to the pipe K for supplying the motive fluid, and it will be found that the pressure in this pipe is suflt cient to sound a loud blast on the call, which can be used for signaling or other purposes.

I am aware that changes and alterations in the form and proportion of parts and details of construction can be made without departing from the spirit or sacrificing the advantages of my invention, and I therefore reserve the right to make such modifications as fairly fall within the scope of my invention.

Having described my invention, what I' claim is 1.
