UNITED STATES PATENT OFFICE.
C. L. ADANCOURT, OF TROY, NEW YORK.
IMPROVEMENT IN ROTARY PUMPS.
Specification forming part of Letters Patent No. 40008, dated September 22, 1863.
To all whom, it may concern.-
Be it known that I, O. L. ADANCOURT, of Troy, in the county of Rensselaer and State of New York, have invented a new and Improved Rotary Pump 5 and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, formin apart of this specification, in which- Figure 1 represents a vertical section or" my invention, taken in the plane indicated by the line .r x, Fig. 2.` Fig. 2 isa similar section of the same, the plane ot' section being indicated by the line y y, Fig. l.
Similar letters of reference in both views indicate corresponding parts.
The principal difficulty with rotary pumps hitherto has been to keep the working parts of the same tight and in the proper working order, and manifold attempts have been made to arrange the packing in the working parts of such pumps so that it .keeps itself tight, land that it provides itself against wear.
To ei'ect this purpose, and to construct a pump which will work tight fora long time, is the object of my invention, which consists in the arrangement of a rounded stem on the back of the packing-pieces, in combination with correspondingly-rounded sockets in the face' 0f the stationary abutment in the cylinder and in the iaces of the sliders in the rotary piston in such a manner that the action of` the water itself keeps said packing-pieces tight. Furthermore, by the arrangement of the side flanges I increase the capacity of the water-chamber.'
To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation with reference to the drawings.
The cylinder A is rmly secured to the wall or to any suitable place, and it is closed on both ends. Openings a a in its circumference connect one with the suctionpipe andthe other with the discharge pipe of the pump. Between these two openings, and iirmly secured to the inside of the cylinder, is the abutment B, the t'a e of which is provided with a rounded socket, b, to receive the packing-piece O. The face of this packingpiece works tight against the surface of the rotary piston D, and a rounded stem, c, on its back, which ts into the socket b, allows said packing-piece to adjust itself so that the pressure of the water, which is greater on one side of the 'abutment than on the other, will keep the packing up tight against the surface of the piston, and prevent a leakage from one side of the abutment to the other.
The piston D is provided with side flanges, d,which work tight against suitable packing, e, in the ends or heads of the cylinder. 1t (the piston) rotates on the shaft E, and it is furnished with three (more or less) sliders, F, which move in and out iu recesses f in the body of the piston. The motion of these sliders is governed by friction-rollors-g, attached to pins h, which project through slots i in the sides of the piston, and these frictionrollers work in cam-grooves G in the inner faces ofthe cylinder-heads.
It will be vnoticed that the recesses fdo not pass clear through from one end to the other of the piston, but leave the apertures closed above the slots I, and prevent an unnecessary leakage of the water. This arrangement also increases the proportionate capacity ot' thc water-chambers. Each of the sliders is provided with a socket, j, and with a packing piece, H, similar to the socket b and 'packing-piece O in the abutment B. These packing-pieces close up tight against the inner surface of the cylinder, and they are kept tight by the pressure otl the water itself,which is necessarily greater on one side than on the other. This mode of packing the abutment and the sliders is very simple, and it keeps the working parts of the pumps tight for a long time without requiring` any attention.
It is obvious that these improvements are applicable to rotary steam-engines as well as to rotary pumps.
What I claim as new, and desire to secure by Letters Patent, is
1. The arrangement of the packing pieces C and H, with rounded stems to lit into sockets b orj, substantially in the manner and for the purpose hert-in described.
2. The combination of the grooved flanges d with the sliders F and piston D, substantially as and for the purpose described.
