Abstract

570,815. Making pipe fittings. JOHNSON, H. C. Oct. 11, 1943, No. 16609. [Classes 83 (ii) and 83 (iv)] [Also in Group XXVIII] Stamping screw-threads ; embossing ; dies.- An end fitting for a hose of the type having a helical reinforcement 2, comprises a coupling member 4 having a continuous or interrupted helical ridge or helical row of projections adapted to make screwed engagement with the helical reinforcement of the tube, said ridge or projections being either pressed from the wall of the member or separately attached thereto. The member 4 may have a wire 5 soldered thereto or a series of studs helically arranged and soldered to the member. A press, for stamping a helical ridge or helical row of projections in the member 4 comprises a base-plate 20, Fig. 5, a block 9 having a semicylindrical recess in which the tube 4 rests, and a die 16 adapted to be engaged by a hammer and having an end guide portion 18 engaged in the baseplate 20 and a lateral extension 12 to which is detachably secured a member 14 which provides a ridge, or, series of projections, extending beyond the face of the part 12. The recess in the block 9 has a helical groove 11 which coincides with the position of the projection 14. The tube 4 is partially rotated after each hammer blow.
