TO ALL WHOM IT MAY CONCERN: I
Be it known that I, CHARLES HARRISON, of the city and State of New York, have invented, made, and
applied to usea certain new and useful Improvement in Cocks or Faucets; and I do hereby declare the follow ing to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is a vertical section of the said faucet,'^and Figure 2 is a sectional plan at the line a: z.
Similar marks of reference denote the same parts.
My invention relates to a gradual self-closing cock or faucet, and is adapted to the supply of water to a `water-closet, or when saidco'ck is made of a smaller size, it is of a character for use with stationary washbasins, baths, &c. l y
My invention consists in a hollow metallic piston upon the lvalve-stern, that acts upon the water in the cylinder of. the cock to cause the gradual closing of that valve by the action of c. spring, and thatdvithout the concussion and hammering action sometimes experienced'in diaphragme and other devices,`snch as cup- Ieathers, heretofore `employed to control the closing of such valves, 'and I form a guide upon the piston-rod working through the valve-stem to steady the said piston and valve in their movement.
In the drawing, a is the barrel of the cock or faucet, la is the inlet-waterpipe and coupling, and c the delivery-pipe.' When this cock is employed for a basin or bath, the lower'end of the cylinder a is flanged to set upon the slab, and the pipe 6 comes up through that slab, and the pipe c forms the hollow arm for the basin. When iitted for a supply-valve for a water-closet, the arm d is employed for attaching the same in place, or any other suitable connections may be employed.
e is the valve-seat between the pipes b and c, and above this is the cylinder f, leaving a water-way, g, around and above the seat e, and this cylinder f may be removable from the barrel a, as in the cock of Charles H. Miller, patented November 26, 1867, or it may be cast withfthe barrel a. I prefer the former, as allowing the valve and all its parts to be taken out without disturbing the barrel a. v
Through the cylinder f are' slots, forming water-ways to the water-way g, and within the cylinder f is the piston Je upon the rod z' that passes through a packing below or within the screw-cap c, and l is a head to said rod z', by which it may be operated upon by hand to press it down, or a lever might be employed for this purpose. I
Below the piston z is a guide, m, that fills the watcr-wayof the valve-seat, e', but said guide is groovcd for thev passage of water, and n is the valve itself, closing against the seat e, and acted upon by the pressure of water and the spring Z that may be placed around the valve-stem z', as shown, or be placed below the valve.
The piston h is made of metal, and hollow or cup-shaped, so that it receives and holds water as it moves in the cylinderf with the valve in closingrthere being a small amount of leakage between the piston and cylinder. This hollow piston h being of metal, is not subject to being compressed or changed in shape by the pressure of water on the valve.- Hence there cannot be the hammering action of the valve upon the seat as in cup-leather valves, where the ram action of the water causes the valve to close by compressing the leather of the piston, and its expansion again opening the valve, and thuscausiug several concussione of the valve on its seat.
In order to insure-the proper filling of the cylinderf, I form grooves, t, near the bottom thereof, through which the water can pass freely when the piston h isdepressed, but when said piston commences to rise as the pressure of the rod iis relieved, the said grooves tare of no further service as the piston moves away from them.
What I claim, and desire to secure by Letters Patent, is-
1. The piston h, formed hollow, in combination with the guide m, valve n, and cylinderf, as and for the purposes specified.
2. The grooves t, within the cylinder `in combination with the pistou h and valve n, as and for the purposes set forth.
In witness whereof, I have hereunto set my signature, this twenty-fifth day of March, A, D. 1868.
CHAS. HARRISON.
