V. J. MILLER WATER ELEVATOR Filed Feb. 13, 19.22

enemies an 17, rear.



Application filed February 13, 1922. Serial No. 586,134.

To all whom it may concern. I

Be it known that I, VERNON J. MILLER, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Water Elevators, of which the following is a specification.

This invention relates to improvements in what may be termed water-elevators, espe cially of the piston-type, and is particularly designed for providing a source of watersupply for houses or dwellings in obtaining such supply from a well or cistern, where a source of water-supply is not available by the facilities provided in cities.

The invention has for its object, among other purposes, to provide for automatically controlling the delivery of the water-supply from the cistern or well to the dwelling or house.

A further object is to provide for simplifying and lessening the parts and to pro-' mote efficiency and out the aforesaid ends or purposes in an inexpensive and expeditious manner.

Other objects of the invention, together with the foregoing, will be apparent from the following description and accompanying drawing thereof.

The invention therefore consists of certain instrumental-ities and features of construction substantially as hereinafter: more fully disclosed and defined bythe appended claim. Y

In the drawing is disclosed the preferred embodiment, or forms, of my invention, wherein it will be understood that various changes and modifications asselate to the detailed construction and arrangement of parts may be made without departing from the spirit or scope of the invention as covered by the claim, and in which drawings:

Figure 1 is a longitudinal section of my invention.

Fig. 2 is a similar view of form of the same wherein the piston is provided with a valve, and the water-inlet pipe is provided with a valved extended inlet member or pipe delivering into the cylinder above the piston.

Fig. 3 is a like section of the invention, the outlet .or house-feed-pipe being shown as having a second valved connection with the piston-cylinder.

Fig. 4.- is a longitudinal section of a two- 7 cylinder and two-piston type of the invention, and

Fig. 5 is a like sectional view of a hori- Zontally arranged type of the invention.

Fig. 6 is a sectional fragmental View showing a slight modification of the previous figures in that the inletwvalve 9 and the outlet valve 12 are arranged in the well pipe 7 and the outlet-pipe 11 respectively, the well-pipe connection in this instance being efiected with thebottom of the cylinder and having connection by means of arms 6 and 6 with the outlet-pipe 11 andintake pipe 11, respectively, the intake pipell? connecting at its upper end with the cylinder at the upper end, above the piston, the valve 9 being arrangedin the well-pipe inr terinediate the connections of the two arms 6 and 6 of the well-pipe 7.

As characteristic features of my invention, I provide a cylinder 1, preferably bot-- tomed, butwhich may be open or closed at the opposite end and within the cylinder is provided a piston 2 having a carrying rod 1 The piston carrying rod 1 is weighted by suitably applying preferably heavy metallic 'members or weights '8 thereon,

whereby the required pressure may be exerted upon the water or contents within the cylinder below the piston, as in forcing or I delivering the water from the cylinder out through theoutlet or housepipe, the water previously, of course, upon thepis ton-upstroke, having been sucked into thecylinder and the intake pipe valve automatically closing, all aslater seen. Suitable mechanical appliancesare employed for' raising or lifting the piston 2 after making its downstroke, as for instance, a cabled wound upon a drum 5 adapted to be hand-actuated or otherwise, as indicated, these l1owever,lbeing only used as expedients and not constituting, as such, essentials ofmy invention, may

be optionally exchanged for other means, as will be appreciated.

A water-inletor intake pipe 6 is supplied to the cylinder 1, laterally thereof and clear down, adjacent its-bottom, or it maye-ven enter the cylinder at the bottom, and to the suitable inlet pipe 6 is supplied a well or cisternentering pipe 7, at right-angles thereto, the connection between the cylinder and said pipes being effected by means of a right angledihollow or tubular member 8, of elbow-like construction. The member 8 is provided with an inlet water pressure-controlled valve 9 adapted, when the cylinder is filled or supplied ith water by suction caused by the upstroke of the piston, to automatically cut oil the outflow of the Water from the cylinder via the inlet .pipe 7.

An outlet or outtake-pipe 10 is supplied laterally to the cylinder 1, or it may even enter the bottom thereof, or it may connect with the inlet-pipe intermediate the checkvalve thereof and the cylinder, the check valve in the outlet pipe being suitably arranged in plane above the check-valve ot the intake pipe. The outlet or outtake pipe 10 has supplied thereto a pipe 11 adapted to be led to a dwelling or house, or other point to which it may be desired to convey the water for convenience in use. The con-- nection between the outtake or delivery pipe and the pipe 11 is effected by means of tubular or hollow right-angled, or elbowlike, member 12, which is provided with a water-pressure-controlled valve 13, adapted. while the cylinder is being tilled or supplied with the requisite quantity of water, as pre determined by the weighted piston, and during the down stroke of the piston, to auto- *matically open up communication between. the cylinder 1 and the pipe 11 via the pipe 110 and for the delivery of the water from the cylinder, the valve 9 automatically closing under the water pressure in the cylinder.

In the form. or modification ot the invention as disclosed by Figure 2, l; en'iploy piston 2 having a downwardly opening valve 2", and provide the water-intake pipe with a valved pipe extension l t, effecting connection with the cylinder at a point pro- 'viding also for the delivery of water above the piston, the valve of the extension pipe 14: bein indicated at l ih'thus providing for b L Q supplying water into thecylinder both below and abovethe piston as shown.

in the form or modification, as disclosed "by Fig. 3, l have shown the Fig. 1 form of my invention, as provided with the waterintake valved extension pipe 1d and its. valve 14 also the outtake pipe 11 thereof as having a valved connection 15' with the cylinder 1, adjacent the upper end of the cylinder.

This arrangement is double-acting. [is the piston makes its down stroke the water enters the outlet pipe, at the lower end oi": the cylinder, is thence drav-Jn'into the cylinder at its upper end, and, upon the upstroke of the piston the water is forced through the outlet pipe connection at the upper end of the cylinder, and at-the same time the cylinder is being filled from the pipe connected at the lower end. It does not matter whether the pipes, at the upper end, are connected thereto laterally or to its top (the head), or angularly or-otherwise,

the same arrangement or connection being also applicable to the bottom of the cylinder and the inlet pipe and the outlet pipe may enter the cylinder from the same pipe by means of a T provided with suitable valves.

In the form or modification as disclosed by Fig. 41, I have shown my invention as embracing a multiple of cylinders, with a common intake pipe 16 and a common outtake pipe 17, the intake-pipe having valved pipe connections in multiple form both at the upper and lower ends of each cylinder, as 18 and 19, respectively; also the outtake pipe having valved pipe connections, in inuitiple form, both at the upper and lower ends of each cylinder, respectively, as at 21 and 20. This arrangement is a multiple ct that shown in Fig. 3 except that the weights on the pistons are arranged to counter-balance each other.

In the modification or iorni of my invention as disclosed by Fig. 5, l have shown the same embracing the cylinder with its piston-rod extending from each side of the piston and adapted to be actuated from each end, and by the actuating cable and drum or pulley, with the weight, as above shown. adapted to function with the parts arranged horizontally, the same otherwise being devised along the general lines of the form or modification disclosed by 3.

As disclosed in the modification designated as Fig. 6 of the drawings, it will be observed that l have shown the inlet-valve 9 and outlet valve 12 as arranged in the well pipe 7 and the outlet pipe 11, respectively, the well-pipe connection, in this instance, being eltected with the bottom ot the cylinder and having connection by means of arm-pipes 6 and 6 with the outlet-pipe 11 and inlet pipe 11*, respectively, the pipe 11 connecting at its upper end with the cylinder at the upper end, above the piston, the latter being provided with a valve similarly as the piston in Fig. '2, the valve 9 being arranged in the well-pipe intermediate theconnections of the two arms 6 and 6 of the well-pipe 7.

It will be observed that, referring more particularly to the disclosure of Fig. 6, wherein the device functions to take in the water intothe upper end of thecylinder, the valve 9 ot the well-pipe 7 is not functioningshould not function then the outtake then being by way of the arm-pipe G te the outtake or service pipe 11, this obviously being necessary, otherwise .the water would return or pass back through the pipe '7 into the well, the intake in this case being by way of the arm-pipe 6 to the service pipe 11.

It will be seen that by the above construction a water elevator has been provided which can be used in place of a hand-operated pump or a small gasoline engine, for



furnishing water in a private water system,

for example; to and through a house, park, garage, lawn or wherever water is required.

The device operates as follows:

The weight 3 carrying the plunger is lifted by hand with the aid of any convenient mechanical device, such for example as the one illustrated in the drawings. Considering Fig. 1 when the weight is raised the plunger being raised also, the inlet valve is opened and the water is drawn into the container 1. When the weight and plunger are allowed to fall by gravity, the outlet valve is opened and water is forced out of the container 1 through the outlet valve and into the outlet pipe 11.

Referring to Fig. 2, when the weight and plunger are raised the inlet valve 9 is opened and water is drawn into the container 1. On the downstroke of the piston the outlet valve 13 is opened and water is forced out of the container 1 and into the outlet pipe 11 to the point of distribution. Furthermore in the construction shown in Fig. 2, on the downstroke of the piston a certain amount of water will be drawn into the container above the piston through the up er inlet valve 1?; thus water flows in t e space above the piston to occupy the increasing volume as the piston moves down. When the piston moves up the upper inlet valve 14-. is automatically clos d and the water that is above the piston is 'forced through the piston by means of the downwardly opening valve 2* provided in the piston.

The construction disclosed in Fig. 4 operates in substantially the same Way as the opened at the same time and closed at the same time, and the valves 13 and 14 are opened at the same time and closed at the same time. On the downstroke of the piston 2 water isforced out through the valve 13 and drawn in through the valve 14*. On the upstroke'of the piston water is forced out through the valve 15 and drawn in through the valve 9.

I claim and desire. to secure by Letters Patent:

A device of the type described, including a water-containing or receiving cylinder, a weighted valve-equipped piston arranged in said cylinder, the valve of said piston opening downwardly and delivering into the cylinder as the piston performs its up-stroke for delivering the water from above the pistondown into the cylinder, a valved intake delivering into thecylinder above the piston, a second valved intake delivering into the cylinder below the piston and a valved eduction pipe connected with the cylinder at the lower end thereof, adapted to discharge the water entering the cylinder at a common point therefrom.

In testimony whereof I aflix my signature.
