WILLIAM CURLETT, OF SAN FRANCISCO, CALIFORNIA.
PIPE-COUPLING.
SPECIFICATION forming part of Letters Patent No. 545,877, dated September 10, 1895.
Application led December 21,1894. Serial No. 532,546. (No model.)
To @ZZ whom t may concern,.-
Beit known that I, WILLIAM CURLETT, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Pipe-Couplin gs; and I do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in that class of detachable pipe-couplings which are designed especially for connecting a lead or soft-metal pipe-section with an iron or hardmetal section; and its novelty will be fully understood from the following description and claims, when taken in conjunction with the accompanying drawings, in which- Figure l is a diametrical section of my improved coupling, which is adapted to effect the connection of one or two lead pipe-sections to an iron section; and Fig. 2 is a similar View of a modified construction adapted to effect the connection of a lead pipe-section to an iron pipe-section.
Referring by letter to said drawings, and more particularly to Fig. lthereof, A indicates an iron or hard-metal pipe-section, which is exteriorly threaded.
B indicates lead or soft-metal pi pe-sections, and C indicates the coupling-sleeve of my improved coupling, which is preferably of the proportional diameter illustrated. This coupling-sleeve C is interiorly threaded, as illustrated, for the engagement of the thimble or thimbles, and it is provided at or adjacent to its middle with an annular flange D, the inner edge of which is threaded, as shown, to engage the exteriorly-threaded pipe-section A.
E indicates the hard-metal thimbles of the coupling. These thimbles have their outer ends contracted, as shown, and they are provided at their opposite ends with exterior threads a., which are designed and adapted to engage the interior threads of the couplingsleeve.
In using my improved coupling to connect a section of lead or soft-metal pipe and a section of hard-metal pipe the hard-metal section is screwed into engagement with the threads of the annular flange D and a hardmetal thimble E is placed on the lead or softmetal section.
The end of the soft-metal section is then iiared by any suitable device and the hard-metal section is introduced therein, after which the coupling-sleeve is screwed up on the hard-metal section, when the interior threads of said coupling-sleeve, engaging the exterior threads ct of the thimble E, will draw said thimble toward it. This movement of the thimble E will force the soft metal of the section B into the spaces between the threads of the section A and will crowd the end of said section B between the thimble and the annular iiange D of the coupling-sleeve, and consequently it will be seen` that the connection between the two pipe-sections A B is rendered thoroughly water-tight and there is no liability of the said sections being casually disconnected, which is a desideratum.
When my improved coupling is employed to connect two sections of soft-metal pipe to a section of hard-metal pipe, a short section or union of hard-metal pipe and the two thimbles E are employed, and the connection is effected in the manner illustrated in Fig. l.
In Fig. 2 of the drawings I have shown a more simple construction of coupling for connectin g a soft-metal pipe-section B and a hardmetal section A. This construction comprises a hard-metal thimble E, similar to those shown in Fig. l; but the coupling-sleeve C,which is provided with interior threads to engage the exterior threads of the thimble, differs from the coupling-sleeve shown in Fig. l, inasmuch as its annular flange D', which is interiorly threaded to engage the section A, is at its end instead of at an intermediate point of its length.
In using this modiied construction of coupling the hard-metal pipe-section is screwed through the annular flange D of the coupling-sleeve and the thimble E is placed upon the soft-metal section. The hard-metal section is then introduced into the end of the soft-metal section, which has been previously flared, after which the coupling-sleeve is screwed up on the hard-metal section, when the interior threads of said coupling-sleeve, engaging the exterior threads a of the thimble E, will draw said thimble toward it, and the soft metal of the section B will consequently be forced into the spaces between the IOO threads of the section A, and the end of said section B will be crowded between the thimble and the annular flange D of the couplingsleeve, for the purpose stated.
Having described my invention, what I claim isl. The herein described pipe coupling comprising a soft metal pipe section having its end flared, an exteriorly threaded hard metal pipe section inserted in the end of the soft metal section, the hard metal thi rnble mounted on the soft metal pipe section and having its outer end contracted and provided at its opposite end With exterior threads, and the coupling sleeve having interior threads engaging the exterior threads of the thilnble and also having a threaded annular flange engaging the exteriorly threaded hard metal pipe section, substantially as and for the purpose set forth.
2. The herein described pipe coupling cornlof the thirnbles andalso having a threaded annular ange engaging the exteriorly threaded hard metal pipe section, substantially as and for the purpose set forth.
In testimony whereof I affix my signature in presence of two Witnesses.
WILLIAM CURLETT. Witnesses: T. MAHONY, E. G. EISEN.
