Description

UNITED STATES PATENT OFFICE.
JOHN MCCLELLAND, OF WASHINGTON, DISTRICT OF COLUMBIA.
IMPROVEMENT IN HYDRANTS.
Specication forming part of Letters Patent No. 37,820, dated March 3, 1863.
To all whom, it may concern:
Be it known that I, J oHN MCCLELLAND, of the city and county of Washington, in the District of Columbia, have invented certain new and useful Improvements in the Construct-ion and Mode ot' Operating Slide-Valves for Fire- Plugs, Hydrants, and for other Purposes; and the following is a full, clear, and exact description of the same, reference being had to the accompanying; drawings, making a part ofthis specification, in which- Fi gnre l represents a top view, closed valve, with stutting-box and wrench. Fig. 2 shows the under side with the valve open, the crank or eccentric to operate it.
My inventon consists in the construction of a sliding valve with its slotted arm operated with the crank or eccentric, through the cap or cover ot' a hydrant or tire plug, in the man' ner hereinafter described.
To enable others skilled in the art to make and use my invention, I will describe it more fully, referring to the drawings and to the let ters of reference marked thereon.
I make the cap or cover A to be used for re-plugs of metal, ot any required form or dimensions, having one or as many nozzles or spouts, B, to attach hose as may be desired. Under each nozzle B, I place a valve, C, of sufficient size to cover the spout b b, which, projects far enough below the cover A to allow the crank or eccentric D to turn between the cover A and the arm or lever of the valve C, which extends out several inches from the portion that covers the spout and is pivoted to the cover A by the screw-bolt a. The face ot the sliding-valve C and the spout b b are dressed olf and ground together and make a water tight joint. On the cover, in the plane with the face of the spout, I have a. rib, d, for the valve to slide on when moved oft the opening E, and also a ledge, e e, to keep it up to its place. On one side ot the arm of the valve c I have a projection, F, through which is an oblong hole, f, into which a large pin or hub, '1, works, the same being attached to the crank D on the under side of the cover A and made to turn about one-third round on a shaft, H, which comes up through the cover and is made water-tight by an ordinary stuffing-box, K. The pin or hub I forms the stop to hold the valve in the proper position both on or oi' the opening. By the key or wrench G applied to the square h on the upper end of the shaft H the valve is easily opened or closed, no matter how great the pressure may be upon it from the inside of the hydrant.
The great advantages of my invention, as will readily be seen, are the simplicity of its construction, no liability to get out of order, become loose and leaky, the valve being in such a position that the pressure of water or steam will always hold it irmly to its seat, 'and the eccentric which moves the valve being applied to act so direct and positive that it will always operate with certainty with a slight power applied to the shaft.
Another advantage my invention has over others known and used is that in a four or more plug hydrant each conduit has its independent valve to let on and shut oitl the water, so that there is no time lost or waste in coupling hose while others from the same iiow are being used.
My invention may be constructed to any sized scale, andwill be equally effective, may be placed in the water mains, to shut ott' or regulate the flow and pressure in the branch pipes, and can be operated instantly in any place where it is applied.
Having thus fully described my invention,
what I claim as new, and desire to secure by The sliding valve C, with its slotted arm F, and the crank or eccentric D, with the cap or cover of a hydrant or lire-plug, in the manner herein described, for the purposes set forth.
JOHN MCULELLAND.
