Description
Background of the Invention
1. Field of Invention
The invention is an improved hydraulic pump which applies electrical energy, air pressure, centrifugal force and gravity to produce hydraulic pressure at low energy expenditure. It is a device which has a plurality of wheels driven by an electric motor which rotates the wheels along a table surface, the surface of which is slotted, and in such slots are located a plurality of levers which, when rolled across, activate a double acting hydraulic piston which produces hydraulic pressure. By the use of air pressure which is applied to a lever attached to the revolving wheels, the effect of centrifugal force and additional weight are applied to the wheels, causing a pressure output at low energy expense.

Description of a Preferred Embodiment of the Invention
Referring now to the drawings, as shown on FIG. 1, there are three major operating areas of the machine designed to combined electrical, centrifugal, and mechanical energy to produce hydraulic pressure. These three levels consist of the energy input level, the energy output level and the rotary table assembly. In the energy input area, an electric motor (10) is mounted to the underside of a stationary table (12), and is mechanically connected to a gear box (11) which turns shaft (15) in either clockwise or counter-clockwise rotation. For the purposes of describing the action of the machine, we may assume only one direction of rotation. By the use of the gears (26), such shaft rotates shaft and housing (27) which is mounted on stationary table (12), which is mounted on non-rotating shaft (28) and supported by ball bearings (not shown) in such a manner as to allow it to freely rotate, and extends through an opening in stationary table (31) and is connected to rotary table (45) by a thrust bearing (47) and lock nut (46) assembly in such a manner so as to allow rotary table (45) to rotate in the same direction as shaft and housing (27).
The second level of operation or the energy output level consists of the equipment located between the two stationary tables (12) and (31). Numerous double action hydraulic pumps (24) are mounted in a circular pattern on table (12) by the use of a welded angle iron bracket (14) and pin assembly (13) in such a manner that as the machine operates, the pumps may move independently in a generally "rocking motion". Hydraulic fluid is obtained from a reservoir (60 on FIG. 2) by use of piping (20) to enter the pumps (24) by open check valves (23). As the pumps operate, the fluid is passed through the open check valves (22), into a hydraulic collector channel (21) to the hydraulic reservoir (60 on FIG. 2), thus completing the circuit. The hydraulic pumps are operated in an up and down manner by the plunger (25) which is mechanically attached by a pin assembly (29) to an "S" configured lever (30) which extends through an opening (34 on FIG. 3) in stationary table (31), such lever (30) being also attached to table (31) by a bracket (33) and pin (32) assembly which allowsit to freely operate in an up and down manner.
To the rotary table (45), is attached bracket (41) which fits into a groove cut in lever (42), such assembly is more fully shown in FIG. 4. Attached to lever (42) is a wheel (40) which rotates freely on lever (42) and rolls along table (31) in a circular path, and in so doing passes over opening (34) and, by contacting "S" configured lever (30), first drives plunger (25) upward, and then downward due to the "S" configuration of the lever, producing the pumping action. Lever (42) is also connected to rotary table (45) by an angle bracket (48) which is welded to table (45) to which is attached a pneumatic plunger (43) which is connected to lever (42) by a hole (not shown) cut into the lever (42). The pneumatic plunger (43) is forced downward by air pressure supplied through air line (44) from an air reservoir (50) which is permanently attached to rotary table (45). The air pressure remains constant in the reservoir at all times during the operation of the machine.
The foregoing is considered illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and, accordingly, all suitable modifications and equivalents may beresorted to falling within the scope of the invention.
