My invention relates 'to a new or improved apparatus by means of which the vis viva or momentum of a mass of water flowing downward from any suitable source, waterfall, or tank may be utilized for forcing, raising, or elevating a portion of said water up to a level higher than the level in the source or tank. The apparatuses of this class, known as hydraulic rams, as heretofore constructed must generally be located in the lower reach or level ofa waterfall and communicate with the upper reach or level through a main or pipe, into which the water circulates with a certain speed imparted to it by the pressure of the head of Water, and consequently with a corresponding momentum which is utilized for producing a shock against a valve suitably arranged for elevating a portion of the water up to a certain height above the lower level of the waterfall. Such devices are objectionable because of the following inconveniences: As they must be located in the lower reach of the waterfall or somewhat above the lower levelof the same, they are liable at certain moments to be completely very small head of water, it only being necessary that the mouth of the inlet-pipe be constantly covered by or immersed in the Water of the source, so as to preventjthe air from penetrating in the said pipe. For the purpose of imparting to the water in the inletpipe the sufficient speed, and consequently the momentum necessary for producing the mechanical effect desired, I provide at a suitable point of the inlet-pipe a'device, such as a suction-pipe, acting by depression, so as to cause the flowing of the horizontal column of liquid contained in the inlet-pipe.

In order that my said invention may be readily understood by any person skilled in the art, I will now proceed to describe the same fully with reference to the accompanying drawing.

The accompanying drawing shows my invention in vertical section,

A is a tank or any other receptacle in which the water of the source or waterfall is collected. The tank A communicates through an inlet-pipe B with a chamber C, the under side of which is provided with an opening controlled by a check flap-valve D and a vertical pipe E, leading to the bottom of a well or to the lower reach or level K of the waterfall,

and preferably provided at its lower end with a sliding valve or cook G or any other suitable means for opening or closing the said pipe. The front or right end of the chamber O communicates with an air-reservoir 11 through an opening controlled by a valve F, actuated upon by a helical spring '1, and on the air-reservoir H is branched the elevatingpipe R. The axis or shaft P, onto which is keyed or otherwise secured the check flapvalve D, is provided at its outer end with a bell-crank lever or arm N, bearing an adj ustable weight 0 and the swinging movements of which are limited by two spring adjustable buffers m and n.

In certain cases, (such as for supplying towns with potable water,) where the available quantity of potable or filtered water is comparatively small, it is often necessary to raise.

this whole quantity. This I may effect by utilizing any dirty or not potable Water. In

said potable water is collected into a reservoir X, while the' motive dirty water is fed into the apparatus from a tank or reservoir, such as A. v

Inside the chamber 0 a movable disk or piston U is secured to one end of a bag-like corrugated membrane V, made of india-rubber, leather, thin metal, or any other suitable elastic material. The edges of the other end of said membrane are attached to the front or right end of the chamber 0, so as to form a' water-tight collapsible chamber S, communieating with the air-reservoir H through an opening normally closed by the valve F, pressed by a helical spring T, and with the potable-water reservoir X through a pipe Z, controlled by a downwardly-opening Valve Y. Inside the chamber 0 is fixed an annular stop U, the object of which is to limit the rearward stroke of the disk U, and on the front end of the chamber 0 is provided a cock 0",

enabling to discharge any water which might eventually leak into the space comprised between the membrane V and the wall of the chamber 0 in the case where the disk or piston U would not be absolutely water-tight.

The working of this device is as follows: Assuming that the tank A, the inlet-pipe B, and the part of the chamber 0 situated at the left of the disk or piston U be filled with motive (not potable) water, and the collapsible chamber S, the air-reservoir H, and the elevating-tube R be filled with potable water which has been fed from the reservoir X through the pipe Z when the apparatus is. started by opening the sliding valve or cook G and as soon as the check flap-valve D is closed by the pressure of water flowing through the pipes B and E the motive water circulating in the inlet-pipe B and chamber Crushes orimpinges, owing to its momentum,

while the valve Y remains closed. When the momentum of the water is expended, the spring T closes the valve F, and the greater pressure of the water in the reservoir X, the level of which is higher than the level of the motive water in the tank A, opens the valve Y and forces back the disk or piston U to the left end of its stroke in close contact with the annular stop U, thus expanding the cham ber S and filling it again with potable water, whereafter the same working is repeated.

The membrane V and disk U might be replaced without departing from the nature of my invention by any other suitable device constituting a movable water-tight partition between the potable and not potable water, and for holding the disk U in a vertical plane a helical spring may be provided into the chamber S.

I do not wish to limit myself to the location of the reservoir for the potable Water above the raising apparatus.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, what I claim is In combination, the horizontal pipe B, the pipe E leading down therefrom, the valve D controlling the pipe, means for opening the valve, the disk U movable in the pipe B, the valve F with its spring for closing the valve against the pressure from the flow of water through the pipe, a reservoir connecting with the space between the disk U and the valve F, and the flexible material for holding the disk U in normal position, said valve and diaphragm being arranged transversely of the horizontal pipe and operating horizontally, substantially as described.

' In witness whereof I have hereunto set my hand in presence of two Witnesses.
