Abstract

352,801. Rod couplings. DARDELET THREADLOCK CORPORATION, 120, Broadway, Manhattan, New York, U.S.A.- (Assignees of Thomson, A. M. ; 636, Mt. Prospect Avenue, Newark, New Jersey, U.S.A.) Sept. 5, 1930, No. 26557. Convention date, May 24. [Class 99 (i).] In a sucker-rod for deep-well pumps, comprising sections coupled by threaded joints, each upper section has a rounded end 17a engaging a conical or rounded seat 14a in the box on the lower section, the sections being out of contact between the end 17a and the threads 13. The grooves are wider than the threads and, when the rod sections are forced apart by contact of the end 17a with the bottom of the box, the coned tops of the threads 13 in the box join on the coned bottoms of the grooves 18 in the rod. The diameter at the bottom of the grooves 18 is the same as the normal rod diameter and the cross section of the box has the same area as the normal rod cross section. The ends 11 of the box are tapered and the sections are without abrupt change of form, in order to obtain a stream-line contour. The sections are formed with squared portions to receive a wrench. Specification 242,299, [Class 80 (iii), Linkwork &c.], is referred to.
