lUNITED STATES PATENT CTT-Ion SYLVESIER G. MASON, OF ELBRIDGE, NEW YORK.
IMPROVEMENT IN PUMP-PlsToNs.
`Specification forming part of Letters Patent No. 57,531, dated August 28, 1866.
To all whom fit 'may concern.-
Beit known that I, SYLvEs'rEn G. MAsoN, of Elbridge, in the county of Onondaga and State of New York, have invented a new and useful Improvement in Pumps; and I do hereby declare that the following is a full and eX- act description thereof, reference being had to the accompanying drawings, making part of this specication.
Figure l is a central vertical section of a pump-cylinder with my improvement applied thereto; Fig. 2, a perspective view of the inner portion of the piston and the valves; Figs. 3, 4, and 5, views ot' the valves in thc various positions they are placed for planing` and lit,
ting.
Likeletters of reference indicate corresponding parts in |all the figures.
My improvement belongs to that class of doubleacting force-pum ps in which the water passes through the interior of the piston to a hollow piston-rod, where it is elevated.
The invention consists in the combined construction and arrangement of the piston, consisting of two side segmental valves, with au interior chamber, the whole fitting within the piston-rim in such a manner as to insure a direct flow of the water, the construction of the valves being such that they are easily planed and fitted.
As represented in the drawings, A is an inverted piston-rim, open at the bottom, but closed at the top, provided with two inductionports, a a, situated, respectively, on opposite sides, and provided also with a hollow pistonrod, B, screwing therein, and extending to the top of the well. Under the bottom of this rim shuts a cover, C, bolted to said rim by means of bolts b b. This cover is provided with induction -portsV c c corresponding with those above, and is cast with a central chamber, G, extending vertically to the top of the rim, and having the piston'rod opening over it. The sides of this chamber are made plane, and are provided at the top with ports ff, and at the bottom with ports g g.
Against the sides of the chamber rest segmental valves D D, made in the skeleton form shown, and having central vertical ribs or braces, It h, to insure-sufficient strength. These valves ll the whole diameter of the interior of the piston-rim5 but their height is some- What less than that of the interior, so as to al low sufcient play to alternately uncover the ports j' g.
At the downstroke the valves will be Vforced upward, as in black lines, Fig. 1, and the wachoked. The parts are few and easily connected and held.
Peculiar advantages lie in the facility and ease with which the valves may be |nanufactured by the quantity at once.
It will be noticed that the sides are all plane or circular. In order to plane or smooth the sides, a large number of the valves are placed end to end and side by side on the bed of a planing-machine, and clamped or secured in place, where they may be all planed at once.
In Fig. 3 is shown the position for planing' the sides, and in Fig. 4 the tops and bottoms. In order to turn the edges or rims, two valves are placed together, with a block between, so as to form a circle, as shown in Fig. 5, and these are secured to the face-plate of a lathe. In this manner the valves are turned, two at a time, very rapidly.
I am aware of no other pump in which the valves may be planed and fitted so expeditiously and cheaply. In most pumps the shape of the valves is so irregular that they cannot be thus turned out by the quantity.
What I claim as my invention, and desire to'secure by Letters Patent, is
1. The combination of the segmental side valves, D D, with the central plane sided chamber, G, said parts being arranged in connection with the inclosing-rim A and cover C, as described, and the whole operating as set forth.
2. The construction of the segmental valves with plane sides and a circular rim or edge, as described, for the facilities of manufacture, as set forth.
sYLvEsTER e. MASON.
