6 Claims.

This invention relates to pumps and has for its object to provide a force pump located slightly below a small stream of water by means of which it is actuated.

Another object of the invention is to provide in a pump a double lever operated by water for actuating the pump piston.

A further object of the invention is to provide in a water pumping system means for distributing a stream of water whereby a pump will be driven by the force of said water.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings in which:

Figure 1 is a diagrammatic view illustrating my invention,

Figure 2 is an enlarged elevational sectional view of a pump housing and connection,

Figure 3 is an enlarged detail sectional view' of a lever operating member,

Figure 4 is an enlarged top plan view of Figure 1,

Figure 5 is an enlarged sectional view taken it will be noted that my pumping apparatus Ill,

is located somewhat below a spring, or stream designated as A. The distance the apparatus is lo-' cated below the water level a, is immaterial as long as all the operating elements of the device are below said line a, in order that the water will flow freely to said elements.

The pump housing H is substantially rectangular in shape and is formed to include the vert cal walls [2, one of which supports a fulcrum 43 upon which the cylinder block I4 is pivo-tally mounted. An inlet end for the cylindrical block I4 is provided and is connected to a flexible hose 5 which will be connected in any suitable manner with an elevated source of water supply A.

The inner ends and 2| of the relatively long lever pipes 22 and 23 are secured to the block l4, while their outer ends 24 and 25 are secured to and support the tanks 26 and 21. Extending clean through the pipes 22 and 23 and the mem ber 14, is a heavy wire rod 28, the ends 29 and 30 of which project into said tanks 26 and 21. Connected to the end 29 is a valve 3| adapted to open the port 32 into tank 26 when the member 22 is in raised posi ion as indicated in Fig- 2 ure 1 of the drawings; and on the rod end 38 is mounted a valve 33 adapted to close port 3 1 of tank 21 when said tank is in its lowermost position as also indicated in Figure l of the drawings.

Pivotally mounted as at 35 in the top wall 26 of tank 26 is a gravity actuated lever 36, on the outer end 37 of which is a weight 38. The lower and inner end 39 of the lever is pivoted at 40 to the inner end 29 of the rod 28. Fixed to the extreme end 28' of said rod is a downwardly projecting right angularly disposed elongated pin 4! which runs through and somewhat below a loop 42, the horizontal arm 43 of which has a right angular end 44, the terminal of which is fixed at 45 to a flap valve 46 adapted to close the outlet port 41 of the bottom wall of the tank 26. When element 22 is in raised position, the weight 38 will have thrown lever end 31 to the position shown in Figure 1 causing end 39 of said lever to draw rod 28 inwardly of the tank 26, and outwardly of the tank 21, this action causes arm 4| to push against end 42 of link 42 and the arm 44 to a position to close valve 46. In this position the valve 3| is open and valve 33 of tank 2! closed, causing water to flow into tank 2'6. This action reverses the action of like members in tank 21, pulling end 30.

of rod 28 out drawing member 48 with it and causing link 49 to draw arm 50 to open the valve 5| to permit water to flow through port 52 from the tank 21. The action then again reverses and cont nues indefinitely. A support 53 for the rod end 30 is pivoted at 53 to the tank 21 and to said rod end 30.

Mounted on the lever arm 23 is a pump jack 55 p votally connected to the outer end 56 of the piston rod 51 of piston 58 operating in pump cylinder 59. Between the spaced apart bottom walls 6!] and (S! of housing l l. is formed a relatively small water receptacle 52 into which the lower end 63 of cylinder 59 opens. Also opening into the receptacle is a water inlet pipe 54 having a goose neck from which the pipe extends to connect at 63 with inlet 19 of member l4. Located in section 6'! of pipe 64% is a check valve 68. One end of the outlet pipe 89 connects at ill with the receptacle t2 and connects at its other end at H with the storage tank T2. The flexible pipe 16 is connected at is to a supply pipe 14, the inlet end E5 of which opens into said water supply A.

Having now set forth and located the elements of my invention I will proceed to explain its operation. Water flows through the pipe I4 and through the flexible connection [6 to the distributing member l4, from whence it passes through the several ports thereof to pipe 64 filling receptacle 62 which is always full, then the water flows down through pipe 23 now stopped by valve 33, then the water fiows up through pipe 22 through open port 32 and fills tank 26, the bottom valve 45 of which is closed. The weight of water in tank 26 causes it to drop to lowermost position throwing crank 38 to reverse position of rod 28, thereby opening port 34 allowing water to fill tank 21. With the same action the valve 35 is opened permitting water in tank 26 to escape, and as this tank thus becomes lighter, the heavier tank 21 goes down. This cycle continues indefinitely. As lever arm 23 goes up and down it operates the pump piston 58 drawing water into cylinder 59, and with it a fresh supply for receptacle 62 through pipe 64, Which pipe is then checked by valve 58. The piston then goes down forcing its supply of water down into receptacle 62 which is already full. thus water therefrom is forced up into pipe 69 and on through the same and into 'tank12.

the thimble 8! and supports the end link of the,

chain -84. The-other endof the chain is linked to the valve 85 eccentrically, whereby when the -end 78 is forced inwardly. thelever 8!! will rotate thimble'Sl raising hook 132 and with it the chain 84 and valve (15. Reverse action on rod 28, of course, permits thevalve-to .close'by gravity.

.Itis .to be noted that if desired the elements 155 and 51 maybe disconnected andpipe 6'. plugged and another pipe (not shown) connected to pipe 55, .and run tola spring whereby the pump will be operated from the streamA, and water to tank l2v drawn from a spring or other source than said stream A.

.It is thought thatpersons skilled in the art to which the invention relates will be able to obtain a .clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description Having now described my invention that which I cla m as new and desire to procure by Letters Patent is:
