Letters Patent No. 110,334, dated December 20, 1870.

IMPROVEMENT IN DRAUGHTCO 2KS.`

The Schedule referred to these Letters Patent and making part of the name.

'Toall whom it may concer-n Beit known that I, WALLACE' B. BATE of East Somerville, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Draught-Cocks for Liquids, of which tbe following is a full, clear, andexact description, reference being had to the accompanying drawing making part of this specification, in whichl Figure 1 is a perspective Iview of my improved cock, having the end of a leadpipe connected therewith.

Figure 2 is a section th'rough the cock and pipe, showingthe manner in which they are united` This invention particularly relates to water-cocks which are to be attached to lead pipes.

The usual method of attaching'l a stopcock t6 a piece of lead pipe is to make what isvordinarily termed a wiped joint, which consumes a large quantity of solder, (about one pound,) and also requires much time vand labor. one or more plates or back pieces, which are vsecured by screws to hold the pipe and cock in place.

The chief object of 'my present invention is to enableme to dispense with the wiped joint, to make which requires a skillful workman, and also to avoid the Vlabor and expense incident thereto; and, f

v My invention consists in a stop-cock, the rear portion of which is Vprovided with an enlargement, preferably. cast in one and the same piece therewith, the lsaid enlargement having one or more apertures, connected with the interior of the cock, for the admission. of the endof the pipe, which is secured therein by solder Yor otherwise, the back plate for supporting the pipe and cock in place being preferably cast in the same piece with the enlargement.. Y

Toenableothers skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawing- A represents the stop-cock, at the rear end of which, and cast in the same piece therewith, is an enlargement, a, terminating in a back plate, b, provided with It' is also necessary to solder on holes c for the reception ot'jthe screws by which itis secured in place.

Extending through the enlargement at right angles to the passage through the cock, with which it communicates, is formed au aperture, (l, each end of which is provided withva shoulder, e, against which the end of the. lead pipe B'is made to. abut. l

The diameter of the aperture d isa little greater than that of the lead pipe, so as to abrd a space Ybetweenthe two, which is filled with a small quantity of solder, j; by means of which a tight joint of neat` appearanceis easily and expeditiously made at a very triling cost, an ordinary -mechanic being competent to perform this operation, whereas skilled labor is required to make a wiped joint, which` is, moreover,

quite expensive. y l Where onepipe only is to communicatewith the cock the side of the enlargement opposite to the end' of the pipe may be closed or-cas'tsolid.

Where au ironor other 'hard-metal pipe `is to be used, it may be provided with a screw-thread to it a corresponding thread in the interior of the enlarge Instead of, or in addition to, the horizontal passage d, a vertical passage in the enlargement may be pro` vided for the reception ot'` one or more vertical pipes.
