PUMP
INVENTOR BY ATTORNEY Patented Jan. 1, 1924.
UNITED STATES PATENT GEORGE M. ASK, OF SAN JOSE, CALIFORNIA.
' PUMP.
Application filed March 20, 1923. Serial No. 626,347.
T 0 all whom it may concern:
Be it known that I, GEORGE M. As a citizen of the United States, and a'resident of San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Pumps, of which the following is a specification.
It is the object of my invention to provide a balanced pump whereby water may be lifted a given distance with a minimum amount of power.
It is another object of my invention to provide a pump of the character indicated that will be simple in form, economical to manufacture and highly efficient in its practical application.
The drawing is an elevation of my improved pump in a well, showing the operating mechanism, partly in section and partly in elevation.
Referring more particularly to the drawing, I show at 1 a well supplied with water to the'level 2. At 3 is a cylinder arranged in the well and extending one foot below the water level 2 and a distance upwardly into a discharge tank 4: having a water level at 5. At 6 is a piston provided with upwardly opening check valves 7 and mounted to reciprocate in cylinder 3. Piston 6 is operated by a rod 8 connected by a cable 9 to a pin 10 on a plate 11 eccentrically mounted at 10 on a flywheel 12 mounted on shaft 13. The cable 9 operates over pulley 1A mounted on framework 15.- In rod 8 is set a pin 16 extending laterally to engage the upper end of cylinder 3.
At 17 is shown a second piston mounted to reciprocate in cylinder 3 and fitted with upwardly opening check valves 18 and carried by a cylindrical rod 19 enclosing rod 8, this rod 19 having vertical slots 20-20 formed therein to engage pin 16 in rod 8 as shown.
For the purpose of illustrating the operation of the device it will be assumed that slots 202O are one foot long, the pin 16 normally engaging the lower ends of the slots and therefore maintaining the two pistons 6 and 17 a uniform distance of one foot apart. It will also be assumed that the pin connection 10 describes a circle when rotating about shaft 13, the axis of which is four feet long.
If now the pin connection 10 is on its bottom dead center the two pistons 6 and 17 will be inthe positions showngin Figure 1 because pin 16 engaged thetop of cylinder 3 when the piston 6 had reached thelimit of its downward movement this occurring. when p n connectionlO reached the position 21. The piston.17 however continues its downward movement until to a point close to piston 6, reaching the limit of its movement when pin 10 reachesfits lower deadcenter 21 During these movements the water is of course passing up through the check valve to the upper side of piston17, there being no movementof water from tank 4: and the two pistons being immersed in four'feet of water. 7 a
The pin connection now moves through position 21 a distance of two feet to position 21 thereby raising piston 17 one foot and since this movement closes the check valves one foot of water is raised into tank 4; and overflows therefrom, During this movement piston 17 is actually raising but three feet of water, however, because while it is discharging one foot of water at the top the head of water in the well forces water into cylinder 3 below the piston 17, the inflow of water at this end increasing as the outflow at the top decreases.
In the construction herein contemplated,
I provide two other pumps inserted in the well and communicating with the same tank 4, their parts being indicated by the numerals above used followed by an appropriate letter. The pin connections 10-10 10 of the three cables are, however, equally spaced in triangular formation on plate 11. A separate pulley is provided for each cable, the three pulleys being also equally spaced in triangular formation corresponding to the spacing and arrangement of points 1010 -10.
As a result of this formation the following action obtains during the next succeeding movement of piston 13. The pin connection 10 now moves from position 21 to position 21 moving piston 17 upwardly one foot, and since pin 16 has now engaged slots 20 the piston 6 also moves upwardl one foot, the foot of water displaced there y being taken u by the one foot head of water in the wel forcing water into cylinder 3 beneath piston 17. In this movement pistons 6-17 have discharged one foot of water into tank 4,
but since pistons 6 and 17 a have been moved downwardly one foot, and 17 does not move at all there has been no discharge of water from the t-ank. This perfectbalancing of the three pumps continues during the full revolution of Wheel 12 because as the pistons 617 ascend in cylinder 3 they-draw' the Water therein up after them by suction so that they at all times carry, in the presentcase, three feet of Water except during that portion of theirtravelwvhen they pass through the foot .of Water in the bottom of cylinder 3; but"'y'vhile one-set of pistons is'iinmersing' in the said'water the other'two sets are balanced, and asthey" move upwardly'o'utof thes'aid foot ofwaterthey are tionof ea'ch pump or three feet during one complete revolution of Wheel 12.
It is to be understood,ofcourse, that the figures used herein are'illustrative only to make it clear that the several piston strokes, head of atepandr-adius of the circle described by point '10 are properly proportioned to secure the results set forth. 7
It is to be further understood that changes in form construction and method of operation may be made Within the scope of the appended claim.
I claim 'In a pump, a revoluble driving element, an
element'pivotally mounted thereon'in eccentric relation thereto,- a cable attached to said last mentioned-element a distance from the center thereof,- a support for said cable arranged a distance from said driving element, a lift-pump operatively co1n1e'cted-to--said cable and counterbalancing means connected to said second mentioned element and arranged at the apices of anequi-lateral triangle.
