ROTARY PUM P.
SPECIFICATION forming part of Letters Patent No. 254,069, dated February 21, 1882.
V Application filed August 18,1881. (Nomodel.) l
To all 'whom 'tt may concern Be it known that I, JOHN MITCHELL TAY- LOR, a citizen otl the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Rotary Pumps; and I do hereby declare that the following is a full, clear, and exact description of the saine, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference lnarked thereon.
Figure l ofthe drawings is a side elevation of my invention, partly in section, with oney the outer casing or shell of the pump, havinga cylindrical interior chamber.
I have shown in the drawings my invention as applied to a double-acting pump, the chambers being double, as shown. at B C, each of which chambers is provided with the usual feed-pipe, a, containing check-valve b. A shaft, D, passes horizontally through the chambers B C, and has its bearings in the sides of the shell or outer casing, A.
A rotary motion may be imparted to the shaft D by a suitable crank-handle connected thereto, or by other desirable means, such as belts and pulleys, or suitable gearing.
To the shaft D may be keyed or otherwise rigidly connected cranks E, which carry rollers o d, of different diameters, as more fully shown in Fig. l. The peripheries of the rollers c d bear against the interior face of aring, F,revolving eccentrically within the chambers B C'. Each ring F is composed of two sections, e f, which form respectively the outer and inner peripheries thereof. Between the sections e fis placed a packing, g, of indiarubber or other like material, and against or A over the edges of the packing are iiat metal rings or bands h, which are kept in contact with the interior sides of the chambers B C by the elastic packing g, thereby taking up the frictional wear of the metal rings or bands. A
discharge, t', communicates with each 0f the chambers B C, over which is located or placed 6o a cut-0E valve, G, held open by a suitablel spring, It. The lower end of the valve G is pivoted to the casing A, and is formed hollow, so as to contain a filling or packing, l, of rubberv or other like material, and over the edges u of this packing are placed metal plates m. These plates, as they wear from frictional contact with the interiorl sides of the casing or chambers, are forced up in contact therewith at all times by the elasticity of the packing, 7o
thereby acting, the same as the meta-l rings or bands h and packing g, for taking up the wear.
Attached to the free end of the valve G is a shoe,n, concave upon its face to fit or correspond with the convexity of the ring F.
When the shaft D is revolved each crank E moves with it, and by frictional contact of the rollers c d with the interior of the ring F, and frictional contact with the outer periphery of the ring with the interior of the cham- 8o ber of the pump, said ring is carried around with the crank, and at the same time revolves upon its own axis, thereby bringing the entire periphery of the ring in contact with the i11- terior of the pump-chamber during a complete S 5 revolution, and thus preventing wear on one portion of the ring more than another. VThe water is drawn up and discharged in the same manner as in all rotary pumps of this class,
the ring F, as it moves around the interior of 9o the pump-chamber with a rolling cont-act, drawing the water up through the feed-pipe a and driving it around and out through the discharge fi, the valve G being ,closed when the ring F is in the position as represented in dotted lines.
Having now fully described my invention, what l claim as new, and desire to secure by Letters Patent, is-
1. In a rotary pump, the shaft D, having roo connected thereto crank E, carrying rollers c d,
in combination with the rings F, consisting of Y the sections of, packing g, and bauds h, subhereunto subscribed my name in the presence stantally as and for the purpose set forth. of two witnesses.
2. In :L rotary pump, the combination, with the crank E, carryng rollers c d, and ring F, JOHN MITCHELL TAYLOR.
5 of the eut-off valve G, containing packing l and plates m, substantially as and for the pur Witnesses:

pose set forth.
In testimony that I claim the above I have
