Abstract

396,061. Vulcanizing long lengths. WESTERN ELECTRIC CO., Ltd., Bush House, Aldwych, London.- (Bell Telephone Laboratories, Inc. ; 463, West Street, New York, U.S.A.) Jan. 26, 1932, No. 2416. [Class 70.] In means for sealing a vulcanizing-chamber of apparatus for the continuous vulcanization of rubbercovered wire, one or more flexible, perforated discs are held around the wire by a retaining - member yieldingly urged against the discs by fluid pressure supplied to an operating piston under a remotely situated control. The wire with a freshly applied vulcanizable rubber compound thereon, is passed through a chamber 12 comprising a pipe 10 supplied with pressure steam, a steam jacket, and an insulating- covering 24. The wire then passes through cooling and drying steps to take-up reels. A tube 30 threaded on the end of the pipe 10 supports a cylinder 31. and is recessed to receive rubber discs 33 which are clamped by a member 34. An internal hollow tubular member 36 engages a spring-metal sealing-disc 60, Fig. 4, intermediate the centre and circumference of the discs 33. A piston 43 operates the member 36 through a bell-crank 37 with a forked end which bridges the wire. The compressed air which actuates the piston 43 is supplied through a pipe with a reducing-valve, a restricted aperture, a cock for connecting the cylinder 31 to supply and exhaust, a pressure gauge, and pet cocks to effect a temporary control. The discs 60, 61, Figs. 4, 5, and 6, have radial slits out of register and central apertures 65, 66. The aperture 65 is larger than the wire, and the apertures 66 smaller. The escape steam or vapour is confined to a chamber 67 with an exhaust 68. The wire passes over a pulley 70 to the take-up reel. In a modification a discclamping sleeve, adjusted by an arrangement of pivoted bolts and nuts, is arranged to slide on the end of the tube threaded on the pipe 10. The vertical arm of the bell crank is articulated to facilitate cleaning the wire passage. The upper part of the arm is normally retained in position by a spring-pressed detent. Adjustable tappets are provided in the lower arm to limit the movement.
