Filed Mar. 11, 1960, Ser. No. 14,371 2 Claims. (Cl. 103-68) This invention relates to pumps and more particularly to a novel means for operating the same.
The primary object contemplated herein is the provision of a pump assembly wherein the power for operatmg the same is freely available from forces in nature.
More specifically, it is one of my objects to provide a pump assembly designed to be submerged in a body of water such as the ocean, a lake, pond or the like where some undulation or turbulence is present at the surface in the form of waves, ground swells, or tides and to utilize the force created by such undulations or turbulence to operate the pump.
A further object is to provide an anchored, but relatively freely movable float susceptible of rising and falling with the waves on a body of water and connected to a piston to be reciprocated within a submerged pump assembly.
Further objects and the more obvious advantages of the invention will be mentioned or else appear plainly from the description which follows.
This invention consists of novel parts and combination of parts to be hereinafter described whereby the objects set forth are attained, as pointed out in the claims, and illustrated in the accompanying drawings, in which:
FIG. 1 is a perspective view showing a submerged pump assembly mounted for operation according to my invention,
FIG. 2 is a side elevational view of the device shown in FIG. .1 with portions of the pump housing broken away and portions in section,
FIG. 3 is a perspective view illustrating a modified float structure used with this pump, and
FIG. 4 is an elevational view showing a double pump assembly operated according to this invention.
Referring to the drawings a body of water is designated by the numeral and the bottom thereof by the numeral 12. Such body of water may be the ocean, a lake, pond or the like where any turbulence or undulations are present. A block or base 14 is suitably anchored on bottom 12 and need be only at sufficient depth so that the pump assembly 16 is submerged. Thus it will be appreciated that the installation to be described herein may be close to the shoreline, if desired, although this is not required. Pump assembly 16 is mounted to base 14 by means of any suitable pivot or swivel arrangement 18.
No invention is claimed in the pump assembly 16 per so as any suitable type of many commercially available pumps may be usedmy invention relating to the means for operating the pump and not the pump structure. However, for purposes of illustration, I have shown assembly 16 as including the housing 20 in which a piston 22 is mounted for reciprocation and is connected to the piston rod 24 which projects axially and upwardly through suitable packing 26. The piston 22 is shown (FIG. 2) as dividing the interior of housing 20 into an upper and lower chamber 28 and 30 respectively. Inlet ports 32 and 34 connect to the respective chambers 28 and 30 as do the respective outlet ports 36 and 38. Ports 36 and 38 also connect to a common outlet 40 which in turn is connected by a flexible flow line or conduit 42 to the manifold 44 that will transmit water to the point of use. Inlet ports 32 and 34 are provided with the respective check valves 46 and 48 and similar valves 50 and 52 are in the respective outlet ports 36 and 38. It will thus "ice be appreciated that I have used a double action pump for illustration and as shown, when the pump is primed, as piston moves up, water enters chamber 30 from inlet 34 so that valve 48 is open and valve 52 is closed and at the same time water in chamber 28 is discharged through outlet 36 where valve 50 is open and with valve 46 in inlet 132 closed. On the downward stroke of piston 22 the relationship of valves and water intake and discharge is of course reversed and at all times water discharged from housing 20 moves through conduit 42 to the manifold 44 for transmission to the point of use.
With reference now more particularly to FIGS. 1 and 2, piston rod 24 terminates in a suitable fitting 54 to which there is secured a float member 56. The form and shape of float 56 and its means of attachment to rod 24 are not material, the important point being that member 56 is a suitable float or vessel susceptible of floating on the surface 58 of the water 10 so as to rise and fall with the undulations or turbulence thereat. Float 56 is anchored to the bottom 12 and for this purpose, I show a plurality of anchors 60 concentrically arranged relative to base 14 and chains or the like 62 extending from each respective anchor 60 to a spaced fitting 64 on float 56. The means for anchoring float 56 is not criticalthe important purpose being accomplished by any suitable means calculated to maintain a relative position relationship between the float and the pump assembly. As shown in FIG. 1, float 56 shown in the form of sphere is provided with a circumferential vane, rib or fin 66 which extends horizontally from sphere 56 relative to its position in the water for the purpose of increasing the bearing surface against which the water can act and thereby increases the efficiency of the pump by minimizing any tendency for the sphere 56 to become awash in turbulent water.
Thus far described it will be appreciated that float 56 will continually be rising and falling with natural undulations of the water 10 and as this occurs, piston 22 will be reciprocated whereby pump 16 is operated in its normal manner and since the pump is submerged the problems of air lock, loss of prime and leaks are completely eliminated. The arrangement of pivot 18 and flexible line 42 are designed to permit assembly 16 to tilt as float 56 moves within its anchored limits to permit proper action of piston 22 and assure a pump stroke of suflicient capacity to allow for maximum and minimum tides or waves. It should also be mentioned that the intensity of the undulations is important only in regard to the amount of pressure that may be developed and that a relatively quiet appearing pond has sufficient undulation to operate a small pump as has been demonstrated by actual successful use of this method of operating a pump in a small body of water to irrigate adjacent farm land. It can be mentioned here that an inch of movement of the float will produce an inch of displacement in the pump cylinder since water is not compressible and this will take place regardless of the position of the piston in the housing, providing the pump has sufficient over travel.
With reference to FIGS. 3 and 4, the construction and operation of the pump 16 is the same as described so that like parts are given like numerals. In FIG. 3, float 56 is shown formed in an enlarged and elongated tear drop shape attached at its large end portion to fitting 54 having a pivot or swivel means 55 for attachment to rod 24 and at its smaller end is pivotally attached to the upper end 68 of a derrick or tower-like support or standard 70 mounted to the base 14 in spaced relationship to pivot 18. The effect of float 56' on pump 16 is of course the same as previously described with the difference being chiefly in the means for anchoring the float.
FIG. 4 illustrates an arrangement of two spaced pump assemblies 116 on an enlarged base anchor 14'. A tower or support standard 72 is mounted to base 14' intermediate the pumps 16 and to the top 74 of standard 72 an elongated float 76 is pivotally attached intermediate its ends. At each respective end, float 76 carries a pivot or swivel fitting '78 and 8-0 respectively for suitable attachment to the respective fittings 82 and 84 on the respective piston rods 24 of the two pump units 16. Thus arranged, float 76 will be rocked on standard 72 by the undulating Water to simultaneously operate the two pump assemblies 16.
It is submitted that the invention shown and described is aptly suited to achieve the purposes intended and is characterized by a combination of highly useful and mutually cooperation elements that combine their respective and proportionate functions in accomplishing the objects sought to be obtained.
It will be understood that the phraseology employed herein is for the purpose of description and not for limitation and that modifications and changes in the construction and arrangement of this invention can be made within the scope of what is claimed, without departing from the spirit and purpose thereof. It is thus intended to cover by the claims, any modified forms of structure or mechanical equivalents which may be reasonably included Within their scope.
