UNITED STATEs PATENT OFFICE- IsaAc F. vAN-DUZER, 0E MIDDLETOWN, NEW YORK] IMPRovi-:MENTIN PLuMBERs JolNTs.
Specification forming'part of Letters Patent No. 150,109, datediAprl 21, 1874 reissue No, 6,488, dated June l5, 1875; application filed October 16, `1874.
vention the ends of the pipes to he joined are first cut, pared, filed, or otherwise formed so that they may iit into one another. lhe pipes so formed are then held together by a y coupler constructed of lead, over which a layer of solder is wiped or conducted in the usual manner known to plumbers, the object of my invention being mainly to substitute the cheaper metal, lead, for solder in the principal part or base of the joint, the llead being justas good for stiening the joint as solder, and the joint itself being quite'as iirrn when the lead is wiped or coated over with solder,
but that my invention may be fully understood I will describe the same in detail by aid of the accompanying drawings, which form part of this specification.
Figure 1 represents a side view, and Fig. 2 a vertical section, of a T-joint formed according to my invention. Fig. 3 represents a vertical section, and Fig. 4 aside view, of the parts in position before being wiped or covered with solder. Fig. 5 is a plan, Fig. 6 an end view, and Fig. 7 an under side view, of a coupler for forming T-joints. Fig. 8 is a side view, and Fig. 9 a section, of a straight joint Fi 10 is a side view, and Fig. 11 an end view, gf
the coupler represented infFigs. 8 and 9.- Fig. 12 represents a side view, partly in section, of
two pipes ready for coupling. Fig. 13 shows the same with the coupler applied in position to receive the coating of solder.
'In each of the views similar letters of reference are employed to indica-te corresponding parts wherever they occur.
A, Figs. 1, 2, 3, and 4, represents a main and B a branch pipe. ais a conical seating formed in the pipe A, int'o which is inserted the conical end b of the pipe B. D represents a coupler constructed of lead, and formed externally of the shape desired to be given to the finished joint, and having lips lor extensions d adapted to embrace the periphery of I formed as follows: A conical seating, a, in the pipe A and a correspondingly-shaped conical end, b, to the pipe B having been formed by.V
any suitable means, the coupler D is slid or sprung over the pipe A, so that the pipe A may lie in the channel-Dl and be embraced by the lips or extensions d. The conical end b of the pipe B is then inserted into the conical seat a by passing the end b of the pipe B up through the opening d1v in the body of the coupler D. The parts having thus been placed in position, as shown by Fig. 3, a quantity of solder is then poured onto the parts and wiped or conducted around, so as to give a coating or covering, C, to the same and form a neat joint i similar in appearance to' an ordinary plumbers joint. 1n wipin gor conducting the molten solder C around the parts a portion ofthe same is caused to flow in through the openings or holes e to the interior of the coupler D, thereby more'securely uniting the` parts together. -In forming a straight joint a conical seating, a, in the end of the pipe A, and a conical end, b, to the pipe B, is first formed, as shown in Fig.'12. The ends a b being thus shaped, are brought together Within the coupler D, as shown by Fig. 13, after which the molten solderis wiped or conducted around .the parts, so as to form a covering or coating,
G, to the same, a part of the solder C being caused to ow into the interior of the couplingvD through the holec, as in the caseof sthe T.,joint previously described. In all. cases the coa-ting of solder C is conducted a suiicient distance along the pipes A B, as shownat C C', so as to firmly secure all the parts together.
d1 is a circular open- Having thus described my invention, what I claim, and desire to secure by Letters Patent is l: A plumbers joint, constructed by uniting pipes A B within a coupler, D, forming the base or body of the joint,and coating or covering and uniting the parts by means of al.
layer of solder, C, applied externally of the coupler D, in the manner and for the purpose described` I 2. A coupler, D, forformingthe base or body of a plumbers joint, constructed with lips or extensions d, channel or groove D', and opening d1, substantially as and for the purpose described.
3. The combination, with a pipe, A', formed with a conical seating, a, anda pipe, B, having a conical end, b, of a coupling, D, substantially as and for the purpose described.`
4. The combination, with a pipe, A, and a branch pipe, B, placed at an angle thereto, cf the coupler D,\having a groove or channel, D?, to receive the pipe A, and aperture d1 to receive the pipe B, as and' for the purpose del' scribed. l
