Description
- ac~ ro~lncl o~ e Inventlon Although water hammer type pumps have been known for almost two centuries, they generally have not been developed to the point where they may be made available for general private and commercial use. The two major defects preventing such use are:
1. The highly destructive force~of water-hamm r tends to decrease the life of the pump and, over a period of time, damage the two main valves responsible for pro-ducing the water hammer. To protect water conduits andvalves from this destructive force, relief valves and bursting plates are sometimes used. However, there still remains the problem of noise and vibration caused by the constant opening and closing of the valves, making such a pump undesirable for use in urban and residential areas.

To protect water conduits andvalves from this destructive force, relief valves and bursting plates are sometimes used. However, there still remains the problem of noise and vibration caused by the constant opening and closing of the valves, making such a pump undesirable for use in urban and residential areas.
2. To create the water hammer to operate the pump, it is necessary to install a waste valve which shoots "waste"
water out of the pump at every stroke of the water hammer.
While this is relatively unimportant for agricultural use when fresh water supplies are abundant, it is impractical ~,................ .

to pump precious treated water to supply schools, factories, homes, and offices for human consumption with such a waste-ful device.
It may be seen that the enormous savings of energy attained through the use of a pump operated by water hammer are often offset hy the waste, noise and limited life of such pumps.
It is the purpose of the present invention to provide a high efficiency pump of smooth and stable operation and of reduced noise and vibration operated solely by water hammer force.
It is a further purpose of the present invention to provide a high efficiency water hammer type pump wherein the waste valve may remain closed for a maximum period of time to provide a smooth pumping operation able to supply water at a relatively even flow.
It is a purpose of one embodiment of the present invention to provide a water hammer type pump wherein water released by the waste valve may be returned to the pump without decreasing the efficiency of the pump.
It is a purpose of a further embodiment of a water hammer type pump according to the present invention to provide a ~econdary pump which, by utilizing the up and down motion of the discharge valve of the water hammer type pump to drive a piston thereof, is capable of pumping water from underground sources to replenish the supply -- 2 _ source of the water hammer pump.
Numerous other purposes and advantages of a pump according to the present 'invention will become obvious as the invention is now described with reference to the appended drawings, wherein;

Detailed Description of the Invention ' As shown in Fig. 1, a pump made in accordance with , the present invention is comprised of a pump stock 20 having .. . .
fixed at one end a supply pipe 12 for supplying water to ~ said pump stock 20 from a supply reservoir 10, said supply pipe being provided with,-a filter screen 11. The upper ' block 23 of said pump stock 20 is provided with a discharge hole 21 and a flange 23a to which is secured a pressure tank 30. The side wall opposite to the side to which the supply pipe 12 is connected,is,provided with what is generally ~; ~ referred to as a waste hole 22. The upper portion of'said ~ ~ discharge holes 21 is inclined outwardly from the center ,~ ~ to form a funnel shaped seat in said upper block 23 wherein `

, .
lOS3S05 is disposed a valve piston 31 in the general configuration of an inverted truncated cone and which is mounted on a valve stem 32 extending through the upper block 23 in a central position relative to said hole 21. The end of the valve stem 32 extending beyond the valve piston 31 ' is threaded and has locked thereon by means of a nut 32a a plurality of weights 33 intended to increase the weight "
of the valve piston 31 which is made of lighter but more resilient material. The end of the piston stem 32 extending beneath the upper block 23 has disposed therearound a coil spring 34 locked thereto by means of a nut 32b to insure that there is a good seal between the valve pdston 31 and ~he,discharge hole 21.
The pressure tank 30 consists of an air chamber 301 and an outlet pipe 34. Said outlet pipe 34 is provided with a flat valve 35 to prevent any reverse flow of water so that ' water from the pump stock 20 may be transferred to higher, ground.
By controlling theitotal weight of the weights 33 and the amount of tension of the spring 34,'the number of operations the valve performs over a specified period of time may be controlled, raising the overall efficiency of the pump.
' The waste hole 22 is provided in the wall 24 of the pump stock 20 which is at an accute angle of approximately 45 to a level base 25. The bottom edge of a valve plate 40 is pivotally attached to the bottom edge of the waste hole 22 , so that the upper portion may move freely up and down along an arched path of travel. The valve plate 40 is somewhat - 4 _ lOS3505 smaller than the waste hole 22 so the~entire plate may fully enter therein. Layered onto the outside of the 'wall 24 is a resilient water proof gasket 43 having a hole significantly smaller than the valve plate 40 provided through the center thereof, a pressure plate 44 of size and shape corresponding to that of the gasket 43, and a waste valve housing 48 securely provided over the outside of wall 24, the gask~t 43, and the pressure plate 44. By making the center,hole in the prsssure plate 44 and gasket 43 the same size and by virtue of the fact that they are signifi~
cantly smaller than the waste hole 22, the waste hole 22 will be sealed very tightly when the valve plate 40 enterq said waste hole 22 and comes flush with said gasket 43. ' According to the present invention, when the valve plate 40~
~ . .
' ' ~15 strikes ayainst the pressure plate 44, the gasket 43 will , ' act as a buffer, absorbing the impact, and allowing a tight ~' seal to be attained. Due to the impact absorbing function ~
` of the resilient~gasket 43, the seal will be maintained `1 --until pressure intthe!pump stock 23 has been significantly '-~~~~
: ., , - , - , 20 ~ decreased by water escaping said stock 23'into the air, chamber ' 301 by means of the discharge hole 21.
, ~ . .
Through the center portion of valve plate 40 is provided ~;~ ` ,, a valve stem 41, and at the~bottom of the valve plate40-~re - . , provided adjustment bolts '42. By adjusting the length of the valve,stem 41 the amount of movement of the valve plate 40 inside the pump stock 23 and the angle of the opening between the waste valve hole 22 and valve plate ,40 may be , ' _ 5 - '' .
.
lOS3S05 controlled. The waste valve housing 48 is provided with a control rod 46 having one end exposed and extending out of the housing 48. The exposed end of control rod 46 is provided with a knob 460 and a spring 47 is disposed between said knob 460 and the waste valve housing 48. The opposite end of the control rod 46 extends through a throat base 45 provided internally of the waste valve housing 48 and con- .
tacts the waste valve stem 41. The adjustment bolts 42 ~ :
~erve to control the tightness of the valve plate 40 to the inner wall of the pump stock 23. By adjusting the bolts 42 it is possible to obtain the best advantage of the force of the water hammer possible without damaging the pump.
As shown in Fig. 2, one end of a water return p1pe 51 is attached to the lower end of the waste valve housing 48.
15 : An outlet gate yalve 510 is provided at a tee to said pipe 51 and past said gate valve 510 is provided a one way valve :
: 511. The other end of pipe 51 is connected to a return tank 50. Said return tank 50 is provided internally with a hori~
;~ zontal rib 52 over which is hooked or otherwise secured a . I --: .20 tension spring 53. The spring 53 hangs down to the open end of the return tank 50, which ends in a nozzle 54. A steep :~
: sided tray 55 having a diameter substantially larger than that of the open nozzle 54 is hooked or otherwise secured to .
the.free end of the spring 53. A dome like stopper 56 of a resilient material is provided on the floor of the tray 55 capable of sealing shut the ~louth of the nozzle 54. An : elevated base 13 having a diameter less than the main body .
of the tank 50 but greater than that of the nozzle 54 is , :1053505 provided on the supply pipe 12 relatively close to the pump stock 20 and the return tank 50 is mounted therein.
The mouth of the nozzle 54 is generally sealed shut as the tension of the spring 53 pulls the dome shaped stopper 56 thereagainst, preventing water from the supply pipe 12 from entering the return tank 50. However, as the valve plate 40 is closed, much water will be thrust out thereby into the waste valve housing 48 and consequently into the return plpe 51 and return tank 50. The increased pressure produced by this thrusting action will force the tray 55 and stopper 56 away from the mouth of the nozzle 54 and water will flow back into the supply pipe 12. By returning the waste water to the pump in this intermittent fashion at times of low pressure in the supply pipe 12, it is possible to return ; 15 all of the water from the waste hole 22 to the pump stock 20.
In anather embodiment of the present invention the up and down movement of the discharge valve 31 and stem 32 is utilized to drive a second pump to draw water from an under-,: :
ground source and, if desired, supply such water to the '~
supply reservoir 10 of the water hammer pump, as shown in Figs. 4 and 5. ~

According to this embodiment, the return pipe 1-2 is provided with a check valve 512 and said return pipe 51 is connected to the upper chamber of a water drawing pump 60.
Said water drawing pump 60 is provided with a piston 63 in the middle of which is provided a check valve piston 631.
Said piston 63 is connected to a piston rod 61 which extends through the top portion of the water drawing pump 60, th~

extending end thereof having disposed thereon a compression spring 68 for the purpose of aiding the operation of the piston rod 61 and above said discharge valve rod 32, making the operation more sensitive and accurate. At the top o the piston rod 61 there is pivotally secured a lever 62, which is pivotally secured to a support base 67 at a section near the end opposite the end secured to the piston rod 61, said opposite end being pivotally secured to the discharge valve rod 32 by any suitable means. As shown in Figs. 4 and 5 the discharge valve rod 32 extends beyond the bottom of the pump stock 20 and the spring 34 is disposed between the lever 62 and the bottom of the pump stock 20.
The lower end of the said upper chamber 64 of the water drawing pump 60 adjoins a check globe valve 65, the lower end of which is connected to a suction pipe 66 leading to an underground water source. In addition, the upper portion of the water drawing pipe 60 is provided wlth an outlet pipe 69 which leads to the supply reservoir 10 for the water ham~ er pump and is provided at that end with a control valve 691.
Z A hand lever 71 may be attached to the upper end of the piston rod 61 and secured to the top of the water drawing pump 60 by means of a connecting rod 70 (shown by broken lines in Figs.
4 and 5) so that the water drawing pump may be operated manually to fill the sup~ly reservoir 10 should there be an insufficient water supply to facilitate operation of the water hammer:pump.
The lever 62 may be first detached from the pis~on rod 61 to insure easier manual operation.
After attaching the lever 62 to the piston rod 61, and -- 8 _ ~053505 when the water hammer pump has been started as above explained, the steady rythmic up and down move~ent of the discharge valve stem 32 will by means of lever 62 drive the piston rod 61 to operate the water drawing pump to draw water from an under-ground source.
The operation of this embodiment of the present invention is identical in all respects except that to cease operation the valve 691 is close which perform the same function as valve 511 in the previous embodiment. I
In this way, a high efficiency water hammer pump may be provided which eliminates shock, noise, and wasted water so that it may be used commercially to supply houses, schools - and offices with water day and night, with no need for elec-tricity or other power sources.
