V,Specification of Letters Patent.

Application led January 21, 1920. Serial No. 353,000.

To all whom t may concern.-

Be itknown that I, FRAK STOKLOSA, a citizen of Poland, residing at Chicago, in the county oi" Cook and State of Illinois, have invented certain new and useful Improvements in Pumps, specilication.

The primary object of the present invention resides in the provision or" a pump of the lift type wherein the piston within the pump cylinder for elevating the water is raised and lowered by an oscillatory movement of an operating handle operatively connected to the piston.

of which the following is a A further object of the invention is to associate a lweighted lever with a lift pump to equalize pressure during the raising and lowering movement of the pump piston.

Vith the above and other objects in view, the invention consists in the novel form, combination and arrangement of parts herein fully described and shown in the accompanying drawing, wherein like reference characters indicate similar parts throughout the several views.

Inthe drawings,

Figure 1 is a front elevational view of a lift pump constructed in accordance with the present invention, the lower portion of the pump cylinder being broken away,

Fig. 2 is a vertical cross sectional view of the pump shown in Fig. 1 showing the lift piston within the pump cylinder,

Fig. 3 is a cross sectional view taken on line lll-III of Fig. 2 with the valve positioned above the piston head, and

Fig. t is a cross sectional viewV taken on line IV-IV of Fig. 2 with a portion of the piston head broken away.

The invention relating to water pumps of the lift type, there is illustrated a pump cylinder 5 adapted for sinking in a well with the head 6 of the cylinder secured to the well cover 7 by the lateral flange 8 shown more clearly in Fig. 1, while an outlet spout 9 arranged adjacent the upper end of the cylinder head 6 is adapted for the delivery ot water Jfrom the pump cylinder.

rfhe mechanism for elevating the water in the pump cylinder 5` embodies a hollow piston 10 of the form best illustrated in Fig. 2, the piston and cylinder being preferably rectangular in cross section to prevent relative rotary movement between the parts. The upper end 10 of the piston 10 is provided with water passage openings 11 that are normally closed by a flat valve 12 shown in Figs. 3` and 4, the valve 12 having a central opening therein to loosely receive the central boss 13 in the top 10 of the piston. Guide pins 111 extending vertically from the upper end 10 of the piston form guides for the vertical movements of the flat valve 12 while the heads of said pins 14 limit the upward movement of the valve. A piston rod 15 is connected to the piston boss 13 and projects upwardly of the head 6 of the pump.

In order to effect a reciprocation of the piston 10 within the pump cylinder 5, there is provided a frame mounted upon the pump head 6 which comprises vertical bars 16 and 17 between which the lever beam 18 is pivoted as at 19, an adjustable weight 20 being mounted on each end of the lever beam 18 for purposes of weighting and counterbalancing the same. A vertical end extension 21 is carried by the lever beam 18, being braced as at 21 and has a lateral extension 22 connected by a cord or cable 28 to the upper end of the piston rod 15, the cord 23 passing over a pulley 24 mounted in thc bearing 25 at the upper end of the side bars 16 and 17. A sprocket wheel 26 operated by a crank 27 is journaled on the front face ot' the cylinder head 6 and a point above the outlet spout 9 while sprocket wheels 28 are j ournaled at opposite sides of the spout, and over all of which sprocket wheels passes a sprocket chain 29 with the ends connected to cords 30 carried by opposite ends of the lever beam 18.

In the operation of the pump, the crank handle 27 is oscillated to follow the path shown by the curved arrow line in Fig. 1 to effect a rising and lowering of the opposite ends of the lever beam 18 with a consequent rise and fall of the piston 10 within the cylinder 5. During the lowering movement of the piston, caused by its end weight when the arm extension 21 of the lever beam is elevated, the valve 12 moves vertically upon the pins 111 to permit the water in the lower end of the cylinder to pass through the piston openings 11, while during a reverse movement of the lever beam 18, with the rise of the piston 10, the valve 12 seats directly upon the upper end 10 of the piston to elevate the water within the cylinder above the piston for delivery by way of the outlet spout 9. The adjustable weights 20 upon the lever beam 18 insure an easy operation of the pump by counterbalancing the Patented July 20, 1920.
