Abstract
544,621. Making pipe couplings, valves &c. PARKER, A. LA R. Dec. 3, 1940, No. 17198. [Class 83 (ii)] Tube couplings, valve cocks &c. are made from an extruded bar of cross-section roughly conforming to that of the finished articles, and slugs 11, Fig. 2, cut from the bar are die-shaped, so as to form a standard blank from which various finished units can be made by machine working. The standard blank 12, Fig. 3, may be of T- form, in which each leg includes a non-circular head portion 14 and an axially projecting portion 15. The blank is bored, and the non-circular portions are removed,. e.g., from. two of the legs and the axial extension from the remaining leg, so as to form a finished unit having a female counterbored portion 22, Fig. 5, and two threaded. male extensions 21, 24.
