T0 ALL WH'OM IT MAY CONGRN: t

Be it k-nown thatthe following is a. full, clear, andexact description of n. new and useful Improvement in Faucets, invented by me, ALBERT Fontes; formerly of Cincinnati, in the county of Hamilton, and State of Ohio, but` now of thevcity, county, und State of.New Yorlr, reference being-had to the accompanying drawing, and to the letters of reference marlred thereon. l i

This improvementl relates to elastic plug-valves, as used, for instance, in faucets, that is, valves made, say, of India rubber, having a solid character orform;` and my invention consists inencasingsuch a valve by a metallic shield, in such manner as that said shield not only answers toL confine the rubber plug and keep it in proper shape all round, but also serves or may serve to form a valve of a compound character, as regards its bearing-surfaces orfaces, namely, part metal A:and part rubber,without losing its peculiarity as an elastic plugvalve, and so that, when drawn or forced against ite seat 'or seats that are constructed to suit such action, the rubber' forms a softcentral, as it were, contact with its seat, followed up by anoutside bearing of metal upon metal, as the shield is brought in contact with its seat, said shieldalso acting, by its eirternal position, to protect the rubber face of the valve all round, and keep itfrom spreading laterally, whereby a closer tit ofthe `'elastic plug against its seat is secured. v

By th'is, my improvement, the rubber plug is so confined asithatitfmay be kept invproper shape, when used,

for instance, in hot water orlsteam, and the liability to leakage'fand.V binding is. reduced, also 'thefaucet made more ediciont and durable.

In the accompanying drawingi Figure 1 is a central longitudinal section of a faucet having my improvement applied to it, and

Figure 2 a view of the. vulve and working parts detached from the body of the faucet or cock,

The body of the faucet is here shown ns castl in two pieces, A and B, which are screwed together, as seen in fig. 1. The cap C is also screwed to the piece-, us shown in the same ligure. By a common handle, L, the camshaft K is turned, giving motion lto the valve-stem D, and thus opening aud closing the valve. The valve 'is'elastic, and may consist of 5x plug or body E, of India rubber, encased in a metallic shield, which is here shown ns made in two purts, namely, a thimble` Ff, and houd G, tig'. 1, the' head being movable in the thimble. By means of a screw-nut, lI, the elastic body of the vulve may be compressed between the'head G andthe disk portion of n guide, Thus embraced by metal, the rubber will bear a high degree ofbeatwithout undue i expansion. The joint formed by the vulve will be perfectly reliable, and there will be no abrasion ofthe rub Vber under the sevcrest test. l

The valve-seat mny be dat, slightly angular, or oftother suitable form. When the lipof the lhield il' intended to beur upon the valve-seat, the shupe of said shield must conform ta'theahgpgof the seat.l n'order.' to prevent the lip of the shield, as the thmble or-part Fvmay be called, from being pressed t'oo violently nipoti.

the 'vulve-sent, the-.head G of the shield is made capuble of sliding into theflthinibleF, and of again receding from the thimblc as the valve leaves its seat. lAlthough thc shield may thus act in connection with the rubber i to form u metal joint. in combination with a rubber joint, or n combination of Iu metallic valve witha rubber vulve, theimportunce of the shield, us n protection to the elastic valve or plug E, must notbe lost sight of.

The vulve may be mudo with a shield in one piece, a'spring, if'desired, being placed behind it.

The camshaft, K, is shown with ushoulder, which restsv upon a corresponding shoulder in the part or piece l l A of the cock, as seen in fig. 1. This supports the cam-shaft, and prevents it from resting upon the-stemD Between the shoulder on the cam-shaft ondlower end of the cup C, may be a stung-box, lille-d with elasti' packing, P. v .l

By'tliis arrangement the camshaft K has u. free movement inthe cup C, and yet the water is prevented from escaping through thc joints of said cap.

The cam at thc lower cnd of the shaft K is shown embraced by u yoke in the vulve-stem D,Kso that the turning of the handle .L gives s. positive motion to the valve.- The length ci'l the stem D should `be such as that v the csmhsrhen its stroke is completed, will bring the valve .rmly upon its se'at, without violence or injury to the valve.

The constructionl may be somewhat varied, without, departing from my invention, and gutta perche or other elastic substance may be used, instead of Indio rubber; therefore, I do not conlineniyself to the precise arrangement set forth, so long as the same object or objects 'is or are attained. l

In my pctentsof v18551;.nd 1858, di'erent forms of elastic plug-valves are described; therefore, I'ldo not here broadly claim suchdevice. In neither of' these patents is the Vrubber plug completelyor equivalentlyv encased and confined, and therefore not.' so well adifpted Ate hot fluids, .nor do snch valves present a. metallic bearing or face outside the rubber plug, 'so esto protect and confine the outer bearing edges of the rubber, as yis thec'ase in this my improvement.

Having mus muy described my impl'vement, what I claim, and desire to secure-by Letters Patent of the I United States, is l 1; Ail-elastic plug-vulve, encased in Ythe'alsoire-described metallic shield, for the pnl-poses set forth. *y 2. .Anelastic plugvalv, encased ina metallic shield, as described, when the shield is constructed to present. a' valve-face, vWhclriel transverselyor lnterelly exterior to the plug, in oombinticn with va. vulve-sent or seats to both the elastic and metallic faces ofthe valveI substantially as' sharm and described.
