Abstract

620,504. Making screw sockets. VAES, M., and VAES, P. E. Aug. 15, 1946, No. 24335. Convention date, Jan. 23. [Classes 83 (ii), 83 (iii) and 83 (iv)] Coiling helical tubes; corrugating; inserting screwed bushes.-A hand-tool for forming and inserting non-ferrous linings in the holes in sleepers to protect the wood from rust comprises a socket tapped at 8 correspondingly to the thread of the coach screw and a mandrel 5 with a thread 4 either identical with or slightly smaller than that of the screw. Strip 3, to form the lining, is introduced by a slit 10 with its sides 11, 12 inclined at the helix angle and with a radial side 14 to guide the strip into the slotted end 6 of the mandrel. The mandrel is screwed into the socket, drawing in the strip 3 that is now guided by the tangential side 13 of the slot. The lining when formed is removed on the mandrel which is next employed as a tool for inserting the lining in the sleeper. After insertion, a sharp twist of the mandrel in the reverse direction breaks off the tang remaining in the slot and the mandrel is unscrewed, leaving the lining in the hole.
