IMPROVEMENT IN COMBlNED STOP-COCKS AND T-JO|NTS.

Specification forming part of Letters Patent No. 178,312, dated June 6, 1876; application filed April 12, 1876.

in proper relation with the T-joint, three wipejoints being thereby rendered necessary in' providing the T-joint and stop-cock for the boiler -an ugly and cumbrous job being thus produced, and the joints being liable to sweat where the T-joint and the stop-cock are inserted, all this being well understood by plumbers, and requiring no more specific description here.

The object of my invention is to obviate all this, by providing as a new and complete article, ready for use, a combined T-joint and stopcock t'ormed in one, with a short sectionot' pipe, and provided at each end with a screwthread. By this means the insertion of the T -joint and stop cock by the clumsy wipe.- joints is avoided, and provision is made for the insertion of the appliances into the pipe at a mere fraction of the cost involved in the practice of the usual method the device complete being simple, cheap, strong, and constituting a new article of manufacture and trade.

Figure l is a side View, and Fig. 2 a longitudinal section, of a combined T-joint and stop-cock made according to my invention.

. A is the stem of the T-joint, internally threaded, as shown at a, to receive any pipe desired to be attached thereto, and B is the l T or head of said joint.

TheT or head B is formed in one portion of a short section-pipe, O, in the opposite ends of which is formed the socket b, which receives the plug D of the stop-cock-this latter furnished with the usual handle 0.

Upon the two opposite ends of the device, as thus constituted, are formed screw-threads f, upon which lengths or sections of pipes may be screwed when the stop-cock and T joint are applied in position with reference to the range-boiler or similar apparatus.

It will be observed that the T-joint A B, the stop -cock D c with its adjuncts, and the screw-threaded ends f, are all formed in onethat is to say, taken together they constitute a single device, apparatus, or piece of mechanism, which would fail to accomplish its in tended purpose if any or either of the just herein-named parts were removed and that the said apparatus is fitted into its place, when applied to use, by its threaded ends f, aforesaid; the troublesome, expensive, and clumsy wiped joints, ordinarily requisite in the attachment of a stop cock and T -joint to the pipe of a range-boiler or like apparatus, being entirely superseded and done away with, a much neater and satisfactory, aswell as much cheaper, job being secured.

What I claim as my invention is The herein-described new article of manufacture, comprising the T- joint A B, short pipe-section (J, stop-cock D b c, and the ends F, constructed with the screw-threads f, the whole combined, constructed, and arranged substantially as and for the purpose herein set forth.
