MULTIPLE CYLINDER RECIPROCATING PUMP WITH RACK AND PINION ACTUATING MEANS Filed March 10, 1950 //V VE/V TUE Patented Jan. 19, 1954 MULTIPLE CYLINDER RECIPROCATING PUMP -WITH RACK AND PINION ACTU- ATIN G MEANS oharleso. 'Kruse, Bothell, Wash. Application March 10, 1950, Serial N 0. 148,881
' 3 Claims. (01. 103-170) This invention relates to pumps. Among other objects the invention aimsto provide a pump especially for liquids which is more efiicient than other-pumps known tome in that t it will lift water .or other liquids to a higher elevation with less power.
, Another object is to provide a pumping system and method whichpermits pumping by remote control, that is,'with thesource of power located considerable distances away and at any convenient point. j
Another object is to: provide a pump where parts are very largely standard'or stock parts, hence may be readily manufactured and easily repairedor renewed, in the event of breakage, corrosion or wear.
Other objects will be apparent from the following description.
The invention is described in connection with drawings which show one of the many embodiments of the invention contemplated by me. It will be understood that the invention is not limited to the showing of the drawings; its scope is defined by the claims which are appended hereto.
In the accompanyingdrawings forming a part of this specification,
Fig. 1 is a perspective view of a' complete pump installation embodying the invention;
Fig. -2 is-a'side elevation of the same, on a slightly. larger scale;
Fig. 3 is a side elevation; on the scale of Fig. 2, the parts being viewed from the right side of Fig. 2;
through a novel rack mechanism to be described later. Pistons 20, 2 I, as shown in Fig. 2, reciprocate in the upper ends or cylinders of vertical pipes 22, 23 respectively, and said upper pipe ends terminate within the tank in perforated guides 24, respectively through which the liquid is discharged into the tank. Obviously a tank is not necessary, and another form of base for the motor and the parts operated by it may be used.
The lower ends of the pipes 22 and 2 3 which are filled with liquid being pumped, as shown,
. are connected to the pump cylinders 3| and 32 by Fig. 4 a horizontal section on line i -4 of Fig. 2 but on a larger scale;
Fig. 5 is an enlarged side elevational view, partly in vertical section showing the rack bar and its drive.
Referring particularly to the drawings, and first to Figs. 1, 2 and 3, the preferred arrangement of parts may include a tank ll having an overflow pipe or discharge l2, said tank being shown open at the top although in many cases it will be closed to confine th liquid being pumped. Secured upon the top of the tank is a motor base l3 carrying a pedestal l4 upon which an electric or other motor I5 is mounted. Motor 15 has a shaft l6 which drives pinions ll, l8 and I l l8 through a reduction gear unit IQ of conventional construction. It will be appreciated that in an actual installation the outer end of shaft IE will be supported by a frame member or pedestal (not shown) mounted on the top of the tank or other base. Pinions l1, I8, Il l8 are employed to operate a pair of pistons 20, 2I'
suitable pipes. Bypass pipes 29 and 30 also are connected to the pump cylinders 3| and 32, as shown. The pipes 29 and 30 are provided with suitable intake fittings 52 and 54.
, Now considering Figs. 1, 3, 4 and 5, pistons 20, 2| extend upwardly from the upper ends of the perforated guides 24, 25 and are secured to or integral with loop structures 66, 61 respectively, each loop structure having rack teeth on opposite sides or side portions thereof. Pinions l1, l8 mesh with the rack teeth 68, 69 of loop structure 66.' Motor I5 is slidably mounted as at 10 on its pedestal support I4 so as to move forward and back along the axis of its shaft l6 to bring the large pinion I! into mesh with teeth 68 or alternatively to bring the adjacent small pinion [8 into mesh with teeth 69. As these pinions are driven at the same speed, obviously engagement of the large pinion I1 with teeth 68 of a greater ratio than pinion l8, will cause the loop structure 66 and piston 20 attached thereto to move rapidly during the up stroke, since the large pinion H is of a greater ratio relative to the small pinion l8. Engagement of the small pinion l8 with teeth 69, which occurs when the motor with its shaft is shifted axially, will cause the loop structure 66 and piston 20 to descend slowly. It will be observed that loop structure 66 is offset on opposite sides, to permit pinions I1, l8 (whichare side by side on the drive shaft) to engage the teeth 68, 69 on opposite sides. Loop structure 61 is likewise ofiset on opposite sides to permit pinions Il I8 to engage alternately teeth ll, 12 of loop structure 67.
To shift the motor shaft and its four pinions automatically, loop structure 66 carries at its upper end a tapered shifting cam 15 (Fig, 2) which engages a protuberance or wear block or beveled disc 16 fixed on the motor shaft to slide the motor and shaft in one direction, when the loop structure 66 reaches its maximum or lowest point of descent at the end of its down stroke, and
of the rising assembly to the lowering assembly is of course determined by the ratio of the diameters of pinions I1 and I8.
Obviously many changes in and refinements of the construction may be made without departing from the spirit of the invention as defined in the appended claims. For example, pipes 22, 23 need not be vertical but may be horizontal or curved or have any other shape desirable for the cond-- tions encountered.
Having described an illustrative embodiment of my invention, what I claim as new and desire to secure by Letters Patent is:
l. A liquid pump of the class described comprising a plurality of pistons, pipes receiving said pistons, a piston rod carried by each piston, a loop carried by each rod, each loop having opposite side portions the loops being in substantially parallel relation, a shiitable drive shaft movable transversely through said loops, drive means carried by said shaft and selectively engageable with said side portions of the respective parallel loops for moving the respective pistons in opposite directions, and co-acting means carried by said loops and said shaft for shifting said drive shait transversely of said loops to bring said drive means into selective engagement with said opposite side portions of said loops to reverse the dimotion of travel of said pistons when said pistons reach predetermined positions.
2. A liquid pump of the class described comprising a plurality of pistons, pipes receiving said pistons, a piston rod carried by each piston, a loop structure carried by each piston red, the loop structures of the piston rods extending in substantially parallel relation, each loop structure having opposed sets of rack teeth arranged in lateral ofiset relation, a shiftable drive member movable transversely of the loop structures,

remaining pinions being engageable alternately with said rack teeth on opposite sides of the loop structures, the small pinions alternately actuating the pistons to produce a power stroke at one speed and the large pinions having a greater ratio than the smaller pinions for actuating the pistons to produce a return stroke at a greater speed-and co-acting means carried by said drive member and said loop structures to shift said pinions of said drive member into and out of selected meshing engagement with said opposed sets of rack teeth of each loop structure at the end of each stroke of a loop structure and piston assembly.
