Description

* UNITED STATES PATENT OFFICE.
THOMAS. J. RICE, OF BETHLEHEM, PENNSYLVANIA.
IMPROVEMENT IVN VVP|PE*COUPL|NGS.
Specification forming part of'Letters Patent No. 173,239, dated February 8, 1876 application iled January 15, 1876.
To all whom it may concern.'
Be it known that VI, THOMAS J. RIQE, of Bethlehem, Northampton county, Pennsylvania, have invented a new and Improved Pipe- Goupling, of which the'following is a speciication:
My invention consists-of a socket-piece on the end of each pipe-section to be connected, with one exterior thread screwing into a sleeve-nut, one into each end of said'pieces, and one-end of the nut having finer threads than the other,
l'so that, by screwing the nut onto the nelythreaded socket-piece a certa-in distance, and
then screwing it onto the other, the difference' tions, respectively, and Eis the sleeve-nut for connecting thecouplings by screwing it onto -them,'loy line threads 'F on one, and coarse threads G on the other.
The ne threads are a little longer lthan the I others, and the nut is screwed along them a little farther than it is designed to' be when the joint is completed, and then it is screwed back vonthecoarse thread until the two couplings come tightly together by the differential movements of the different threads.
` Havingthus described my invention, I claim as new and desire to secure' by Letters Patentcouplings C D by means of dierential-threads F Gr, substantially as specified.
