VALVULAR ARRANGEMENT' FOR FAUCETS, 85C.

Specification of Letters Patent No. 17,624, dated June 23, 1857.

To all whom 'it may concern:

Be it known that I, EDWARD HAMILTON, of Chicago, in the county of Cook, in the Staterof Illinois, have invented certain new and useful Im rovements in Water, Steam, and Fluid Coc s; and I do hereby declare that the following is a full, clear, and eXact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1, is a sectional view of the cock. Fig. 2, is a sectional view of the valve., Fig. 3 is a sectional view showing the application of the valve to a basin cock.

The same letters indicate like parts in all the figures.

This invention consists in the employment of a hollow conical perforated valve, in the manner hereinafter described.

In the accompanying drawings a (Fig. l) represents the valve seat; I) represents the rotary conical shaped valve, capable of being turned by handle d, in valve-seat a; e is a cap fitted with a screw about its periphery, closing the orifice at the bottom of chamber or valve-seat a, through which valve b is introduced into its seat. The interior of valve b is hollow and open at the base c is a spiral spring with one end resting on cap e and the other pressing up against valve (b) to keep it in its seat when not so kept in its seat by the pressure of any confined iuid f, (Fig. 2), is an orice in valve b to admit the passage of the fluid when the valve is properly turned for that purpose 5 g g, is the waterway through the cock and the direction of the current therein is indicated by the signs The space between the base of valve b and cap e is sufiicient to admit the free passage of the fluid underneath valve b, from water-way g, and up into the hollow interior of valve b.

To open the cock for the passage of the fluid, valve b is turned by handle d, till orifice f, in the side of valve b is brought coincident with water-Way g, on the side toward the mouth of the cock. To close the cock and stop the passage of the fluid valve is turned around sufficiently to bring orifice fout of coincidence with water-way g.

Fig. 3 represents the application of the valve above described to a basin-cock-wthe mechanical construction of the same being substantially similar to the preceding; a being the valve seat, and b a conical-shaped valve rotating therein; c, is a spiral spring holding valve b, in its seat; g, gis the waterway through the cock-the direction of the current therein being indicated by the signs d, is the handle for turning valve b, and which also operates as a spout for discharging the fiuid at the mouth 7L. The base, however, of valve b, is closed instead of being open as in Fig. 1; and the fluid instead of passing into valve b at the bottom, as in 1, is conducted into valve b, at the orifice f, through a channel or duct i, fi, in the side of hamber a, indicated by the dotted line,

To open the cock and discharge the fiuid valve b is turned around by handle d until orifice f in valve is brought coincident with channel i in the side of valve seat or chamber a. To close the cock and stop the flow of the Huid valve b is turned suciently to carry orificef ast duct i.

The fo lowing useful results arise from my improvement: 1st. The pressure of the water assists to kee the valve in its seat and renders the ceci perfectly tight. 2d. Unlike mostcocks the valve and valve seat do not become leaky by wear when in use; but as the valve rotates in its seat, and is more or less pressed upward into its seat by the water while being turned, the valve and seat by the act of use are ground together and always kept smooth and even.

I do not claim, broadly, the employment of conical valves in water cocks nor do I claim, broadly, the arran ement of valves in such a manner as that t e pressure of the fiuid shall keep the valves tight in their seats. An example of both these features may be seen in O. A. Fautys faucet, 1853. But

What I claim as new in Water cocks and desire to secure by Letters Patent, is

The employment of a hollow conical perforated valve (b), in the manner, substantially, as described.

EDWARD HAMILTON.
