WILLIAM E.l DERRICK, OF JORDAN, NEW YORK, ASSIGNOR T0 HIMSELF' AND AARON BECK, THE SAME PLACE. i'
Letters Patent No. 68,851.2, dated September I7, 1867.
IMPROVEMENT IN PIIM P-PISTON S.
T0 ALL WHOM IT MAY CONCERN:
Be it known that I, WI-LLIAM E. DERRICK, of Jordan, in the county of Onondaga, and State of `New' York, have invented certain new and useful improvements inthe construction of Pump-Pistons;v and I dohereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompany ing drawings, making part of this specification, Ain which- Figure 1 is an elevation of my invention, representing a portion broken away in the plane'ot` the red line o n'fg. 2, so as to show the relative arrangement of the upper and lower sections and the pivoted valve.
Figure 2 is a horizontal section in the plane ofthe red line a: infig. 1, looking down. I
Figure 3 is a detached view of the pivoted valve.
Like letters indicate corresponding parts.
This invention relates to that class called submerged pumps, and'its nature consists mainly in providing such pumps with vertical `or inclined valveseats, so as to prevent the lodgment of any sediment upon the face of the seat, or between it and the valve.
To enable others to make and use my invention, I will describe its construction and operation.`
I make the piston-head in two primary parte, B and D, with un intervening ring, C. The hollow pistonrod P is screwed into the boss A of section B. This and section D are each providedwith arched or chambered water-ports E and F. The two ports in each section open toward those in the other. .The arch of" the ports is formed as seen in ig. l, so as to form a vertical seat or bearing for the wings 'w Yof the valve GL This arrangement entirely prevents the loclgment, upon the `face of the valveor upon its seat, of sand or other sediment, and consequently a close and perfect iit ofthe valve against the seat is always insured. The valve is composed of a metal plate, so made as to turn upon an axial pivot, a, which is cast uponthe web of section D, iig. 2, and has two wings w, figs. 2 and 3, fitted to the ports E and F. Sections B and D are each made with a slightshoulder, z', g. 1, to centre the ring C. The parts are clamped together by screw-bolts b. The object of making the ring C separate is to afford free access to the vertical face of the ports E and F, 'with a file or other convenience for trimming them up. The ring C may he provided at one or more points with a projecting lug or rib to fit in a correspondingV recess in the upper and lower sections B 'and D, so as to secure the desired relativo position ofthe parts in the two sections, as shown in Iig. 2. When the piston rises the ports E are opened, and the water from the upper part of the 'pump passes through these ports and up the hollow piston, at the same time filling the lower portion of the pump. When the piston descends the valve reverses, opening port F and closing E, and the water below is forced up through the -piston and discharged, while the` upper part of the pumprbarrcl is being filled. It might be desir-able, in order to facilitate the moulding of sections B and D, to make the face of the valve-seat more or less inclined in the direction of the dotted lines c, fig. 1, instead of vertical, and place the wings w of the valve on the same oblique line.
I am acquainted with the pump-piston patented to S. B. Mason and C. B. Gill, February 6, 1866, and do not `claim anything therein shown; but what I do claim, is-
The pump-piston, having two sets of induction andl eduction ports E and F, anda valve, G, with two at wings w connected together by a shank, which is held in position by thc solid pivot a upon the lower half D of 4the piston-head, all the parts being constructed and arranged in the manner shown and described and for thel purposes' set forth.
WILLIAM E. DERRICK.
