Application January 15, 1947, Serial No. 722,264
3 Claims.
My invention relates to pumps designed more particularly for pumping water from cisterns or shallow wells for farm or other uses, and one object of the invention is to prov1de a new and useful pump of simple, compact and durable construction, which can be located at any convenient place and utilized for pumping water into an elevated tank from which the water may be drawn as needed.
A further object is to provide a pump into which water is sucked from a well or other source and discharged by a pair of reciprocatory d1- aphragms forming important features of the pump and employment of which dispenses with the use of packing, glands, pistons and other parts subject to friction, wear and the loss of efficiency.
A further object is to provide a pump having a hollow upright frame, casings secured to two oppositely disposed side walls of the frame and provided with reciprocatory diaphragms for sucking water or other fluid into the casings and forcing it therefrom, and mechanism located within the hollow frame and adapted to operate the diaphragms.
Other objects will hereinafter appear and in order that the invention may be fully understood reference will now be had to the accompanying drawings, in which:
Fig. 1 is a vertical sectional view of the pump with some parts in front elevation.
Fig. 2 is a vertical sectional view of the pump, taken on line 2-2 of Fig. 1.
Fig. 3 is a side elevation, partly in section, of eccentric means.
Fig. i is a perspective view of the upright frame of the pump.
Fig. 5 is a perspective view of one of the pum casings.
Fig. 6 is a detail perspective view of a drive shaft and bearings therefor.
Referring in detail to the different parts of the pump, 2 designates a hollow upright frame preferably of rectangular cross section and provided with a pair of oppositely-disposed side walls 4. The frame 2 has an enlarged base 5 provided with feet 1 adapted to be secured upon a platform or other support, not shown. The two other side walls 8 of the frame 2 are united to the side walls 4 and provided at their upper portions with a transversely disposed drive shaft l0 mounted in bearings l2, provided with plates [4 which are secured to the side walls 8. The bearings l2 may be of the ball-bearing type and side portions thereof extend into axially alined openings 2 IS in the walls 8. The shaft 10 is provided at one end with a fixedly mounted pulley l8 which may be driven by an electric or other, suitable motor, not shown.
Arranged within and protected by the hollow frame 2 is an eccentric mechanism comprising an eccentric 20 fixed upon the shaft ID, a ring 22 surrounding the eccentric 20, ball bearings 2| interposed between the periphery of the eccentric and the inner surface of the ring 22, and a yoke 24 having a vertically elongated aperture 26, in which the eccentric 20 and the ring 22 operate. The lower portion of the yoke 24 terminates in a pair of downwardly extending lugs 28 connected for support to the upper ends of a pair of elongated legs 30 fixed at their lower terminals to a bar 32 arranged transversely in the base 6 and fixed at its ends to the side Walls 8. The legs 30 consist of spring metal leaves 33 reinforced by vertically disposed bars- 34; Fig. 3.
Opposite sides of the yoke 24 have integral axially alined circular'heads 35 which extend into axially alined circular openings 38 in the respective side walls! of the frame 2. Each head 36 is provided with a diaphragm 40 secured at its intermediate portion to the head 36 by a circular plate 42 and suitable fastening means, such, for example, as screws 44. Each diaphragm 40 consists preferably of a circular sheet of thick rubber or other flexible material which is clamped to the outerface of the associated side wall 4 by a ring 46 and screws 48. The circular openings 38 are considerably larger'diametrically than the circular heads 36 to leave ample room for the free operation of the diaphragms. I
After the different parts of the pump, hereinbefore described, have been assembled a pair of casings 52 are installed. Each casing 52 has an open side 54 surrounded by a marginal flange 56 which is secured to a corresponding flange 58, on the associate wall 4, by elements 60, so that the casing can be readily removed when desired for inspection and repairs of the parts located therein. Each casing is divided by lower and upper horizontal partitions 62 and 64 into a large intermediate chamber 66, a lower suction chamber 68, and an upper discharge chamber 10. The suction and discharge chambers 68 and I0 communicate with the intermediate chamber 66, through ports 12 and 14 located in the partitions 62 and 54, and controlled by poppet or other suitable self-closing Valves I6 and 18, respectively. Water is admitted to the suction chamber 58 from a well or other source, not shown, through an inlet pipe and a portion of the water flows into the companion suction chamber through a duct 82 connecting the chambers. Each discharge chamber communicates with an air chamber 84 through a tubular connection 86. A discharge pipe 88, leading from the tubular connection 86 may extend to an elevated tank, not shown, from which water can be distributed for use. Water from the companion tubular connection 86 flows through a discharge pipe 8'! connecting the tubular connections 86;.
In practice, when shaft ll] is rotated it imparts a reciprocatory motion to the diaphragms 40 through the intermediacy of the eccentric the ring 22 and the yoke 24. As each diaphragm 40 is drawn outward through the adjacent opening 38, Water is drawn into the associated casing '52 and expelled as the diaphragm is forced into the casing 52. As one diaphragm 4!) draws water into '4 for said resilient legs fixed to the lower portion of the frame.
2. In a pump, in combination, two duplex casings spaced apart and provided with confronting open sides, respectively, surrounded by flanges, a hollow upright frame having an enlarged base and two oppositely-disposed side walls upon which said casings are mounted, each side wall having an opening registering with the open side of the adioinin'g casing each casing having lower and upper partitions whereby it is divided into a lower suction chamber, an upper discharge chamber and an intermediate chamber; means for securing the flanges of the casings to the side walls of the upright frame, valves for controlling the flow of a fluid through ports in the partitions,
, spring means for closing the valves, means for the associated casing 53, the other diaphragm forces water from the companion casing 52, thus a substantially continuous stream of water is forced through the discharge pipe 88 during the operation of the diaphragms 38. Owing to the length of the resilient legs upon which the yoke 26 is mounted, the latter will move in approximately :1, horizontal plane and thereby avoid any tendency to pull upward or downward upon the diaphragms 40, which action would result in a waste of power as it would not aid in pumping water. Friction and wear on the working parts are reduced to a minimumas the ring 22, in describing an orbit about the axis of the shaft 19, does not contact the upper orlower surface of the elongated aperture 26 and little or no friction is developed between the ring 22 and the opposite verticle sides of the aperture 26, or between the ring 22 and the eccentric 2!}, due to the interven ing antifrictional balls 21. Damage to the working parts from extraneous causes is avoided by enclosing them within the hollow frame 2.
From the foregoing'descriptionit is apparent that I have provided a pump which is well adapted for the purpose intended, and while I have shown a preferred form of the pump, I reserve all rights to such changes and modifications thereof as properly fall within'the invention as claimed:
Having thus described my invention, what I claim and desire to secure by Letters Patent, is:
1. A pump comprising a casing having means through which a fluid may enter and leave the casing, an upright hollow frame to which said casing is secured, said casing and frame having registering openings, a diaphragm reciprocably mounted between the casing and the frame to seal said registering openings and force the fluid through the casing, a one-piece yoke connected to the diaphragm and located in the frame, a rotatable eccentric adapted to impart a reciprocatory motion to the yoke and thereby actuate the diaphragm a pair of elongated resilient legs supporting the yoke and extending down into the lower part of the frame, and supporting means supplying the suction chambers with the fluid, air chambers communicating with the discharge chambers, means communicating with the air chambers and through which the fluid is discharged, diaphragms sealing the openings in the frame and adjacent open sides of the casings, and means mounted in the frame between the casings and adapted to operate the diaphragms.
3. A pump comprising an upright hollow frame having a base and two oppositely disposed side walls each of which has an opening therein, a casing secured to each side wall of the upright frame and provided with an open side registering with the opening in the adjacent side wall of the upright frame, each casing having valve con trolled inlet and outlet ports, a pair of diaphragms interposed between the upright frame and the casings and arranged to seal theregistering openings, a yoke in the upright frame and connected at opposite sides to the diaphragms, respectively, said yoke having an elongated vertical opening therein, a rotatable eccentric located in the opening of the yoke and adapted to reciprocate said yoke, means for operating the eccentric, and a resilient leg secured at its upper portion to the yoke and at its lower portion to the lower part of the base of the upright frame.
