IMPROVEMENT IN ROTARY PUMPS.

Specification forming part of Letters Patent N0. 48,604, dated July 4, 1865.

4 and exact description of the nature, construction, and o )eration of the same reference being had to the accompanying drawings, inak- 4 ing part of this specification, in which- Figure l is a side elevation ofthe pump, the

movable side plate being removed, and a portion ofthe rim and rotating cylinder being broken away to show more clearly the working parts.

Fig. 2 is a vertical section on the line a: m, Fig. 1,'the`rotating cylinder being supposed to be rotated in the direction of the arrow, so that y y thereon shall be inline with w Similar letters denote like parts iu the two igures.

This pump is constructed with a vibrating valveron the `periphery ot the cylinder which rotates within the casing, the water which en` ters from a supply-pipe being drawn from the annular space surrounding the cylinder into the interior of the latter, and discharged atan orifice in the sideV of the casing.

To enable others skilled in the art to which my invention appertains to fullywnnderstand and use the same, I will proceed to describe A is an outer casing or cylindrical box containing an annular recess Within it, which is traversed by a piston, G, pivoted at H, so as to vibrate within the slot in the periphery of an open-ended spoked cylinder, C, which is attached to a shaft, D, and driven by a crank, E F. The said annular space within the outer casing communicates by the pipe M with the water-supply, and as the cylinder C, under the impulse ot' the crank, rotates in the direction of the arrow marked upon it the inwardlyprojecting arm G of the valve G strikes against the pin K,which is permanently attached to the side ot' the casing, and trips the valve, so that it passes the abutment on the casing, which is seen in Fig. limmediately above the watersupply aperture M. As soon as the valve Gr passes the abutment it is again thrown out by the spring I, so as to occupy the annular space in the cylindrical casing, being restrained from too great a movement in that direction by the stopper J, which is secured to the inner side of the rotary cylinder, and, of course, rotates Witht, so as to retain the valve in the right position, not quite in contact with the sides ot' the annular space, thus preventing the friction ofthe valve ou the sides of the annular space. As the cylinder revolves the water from the pipe M, being pressed against by the valve, and being prevented from escaping forward, owing to the fitting ofthe cylinderagainst the face of the abutment, is, crowded into the interior of the cylinder and escapes by the pipe or opening N.

The plate B is secured to the side of the casing A by means ot' the screws L through it and the packing-ring.

Having thus fully, clearly, and exactly described thenature, construction, and operation of my improved rotary pump, what I claim therein as new, and desire to secure by Iletters Patent, is-

The combination ofthe casing A and its plate VB and pin K with the rotary cylinder C, vibrating valve Gr G',spring L, and stopper J, substantially as described and represented.
