PUMP.

SPECIFICATION forming part of Letters Patent N 0.. 662,180, dated November 20, 1900.

serial No. 732,317. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM WILDMAN, a citizen of the UnitedStates, residing at Spadra, California, and whose post-office address is Spadra, in the county of Los Augeles and State of California, have invented certain new and useful Improvements in Pumps; of which the following is a full, clear and exact description,reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to certain new and useful improvements in pumps; and my invention consists in certain features of novelty hereinafter described and claimed.

FigureI is a detail side elevation of my improved pump. Fig. II is a detail side elevation of my pump, taken one-fourth the way around from Fig. I. Fig. III is a detail longitudinal section taken on line III III, Fig.

II. Fig. IV is a longitudinal section taken on line IV IV, Fig. VI, showing a complete body-section, the casing being omitted. Fig. V is a detail side elevation of a lower crosshead. Fig. VI is a transverse section taken on line VI VI, Fig. II, a casing being shown. Fig. VII is a lower end view of one of the pumping-sections, showing rods in section and a base-plate. Fig. VIII is a longitudinal section taken on line VIII VIII, Fig. VI, showing the adjacent ends of two body-sections. Fig. IX is a detail longitudinal section taken on line IX IX, Fig. I.

Referring to the drawings, my improved pump is formed with a series of links or bodysections 1, of which any number may be used found most desirable, said body-sections being counterparts of each other and secured to each other by means of bolts 2, passing through lugs 3 on the respective ends of the body-sections. Each body-section is provided with a central tubular or cylindrical body having alongitudinal opening or aperture 5, in which operates a cross-head 6, formed in two parts joined together by means of clamping-bolts '7.

8 represents a piston-rod'secured to the cross-head 6 at 8: said piston-rod being in two sections having screw-threads 9 on their adjacent inner ends, which screw into the cross-head 6 and are held therein by means of jam-nuts 10. The cross-head 6 being in two parts, the piston-rod may be easily connected therewith. At each end of the cylinder 4 are lower and upper pumping-chambers 11 12, the water passing through the opening or aperture 5 and into the chambers 1112 at 13.

On each end of the piston-rod 8 are located pistons 14 15, each formed of two rings 16 17, screwed to each other at 18 and connected with the piston-rod 8 by central screw-threaded collars 19 20, said collars being a hub for the rings 16 17.

21 22 represent spring-closed valves operating loosely on the respective ends of the piston-rod 8, said valves seating against the inner face of the piston-rings 17.

23 represents Waterways passing through the piston-rings, through which the water travels when the valves are open.

24 represents end plates or heads secured to the respective ends of the cylinder 4 at the outer ends of the water-chambers 11 12, said plates having valve-stems 25 secured thereto, on which are loosely mounted spring-closed valves 26. The valve-stems 25 are so constructed that when two sections are joined together said stems interlock or telescope into each other, as shown at 27, (see Fig. VIII,) thus making one stem and one spring serve the office of guiding the valves and retaining the spring.

28 represents water-legs located immediately outside of the tube or cylinder 4 and on the opposite sides of the tube or cylinder and extending the full length of the body-section 1.

29 represents waterways extending through the end plates of the cylinder l, through which the water passes to the water legs 28. The pistons and the piston-rod are operated by rods 30, located on opposite sides of the pumpin which is located a two-part cross-head 37, connected with bolts 38, the side pump-rods 30 having their upper ends connected with the cross-head 37 as shown at 39, in the same manner as they are connected with the crossheads 6. Extending upwardly from the crosshead 37 and secured thereto is a central pumprod 40, which may be connected with any suitable power (not shown) for operating the pump.

41 represents a sleeve secured to the rod at its upper end, said sleeve being open at its lower end, as shown at 42, and telescoping over an inner sleeve 43, said inner sleeve having its lower end secured at 44 to the inner wall of the

section

34, 45 representing a packing-ring secured to the outer sleeve extending down a short distance below its lower end in drder to prevent the passage of water around the sleeve.

My pump may be operated inside of a wellcasing, as shown at 46, (see Fig. Vl,) or it may be operated entirely independent of the Well-casing.

In operation as the rods 30 and the crossheads 6 move up or down, carrying with them the piston-rod 8, the pumping-chambers 11 12 are alternately made suction-chambers or pressu re-chambers, the water passing through the respective valves out and into the waterlegs 28, traveling upward. The lowest section of the pump is provided with a base-plate 47, closing the orifice in the end of the section in order to prevent the water passing downward. (See Fig. VII.)

I claim as my invention 1. The combination of the body-sectionhaving a cylinder located within it, providing water-legs, and a longitudinal opening extending through the cylinder and body-section,

pumping-chambers located at the ends of the cylinder in communication with the opening and water-legs, the heads having waterways and located at the outer ends of the pumping-chambers, spring-valves seating against the outer sides of the heads for closing the waterways in the heads, the pistons each composed of two rings having waterways and screwed together and located in the pumpingchambers, the piston-rod having its ends secured to the pistons, the spring-valves seat ing against the outer sides of the pistons for closing the waterways in the piston-rings, a cross-head extending through the longitudinal opening and secured to the piston-rod, and means secured to the cross-head for reciprocating the piston-rod.

2. A pump comprising a tubular bodyhaving pumping-chambers, means for forcing wa ter through said chambers, water-legs connected with said chambers, an upper section having its water-legs discharged into a central pipe, an opening extending into said upper section, a cross-head adapted to operate in said opening, a central pumping-rod connected with said cross-head, and inner and outer sleeves surrounding said puin ping-rod, and sleeves adapted to telescope with each other and having suitable packing to prevent the passage of water, substantially as set forth.

WILLIAM WILDMAN.
