Title: Improvements in traversing devices for use on winding cables
IPC: B21C47/12
Filed: 1939-06-29
Abstract: 531,265. Coiling cables &c. COMPAGNIE GENERALE D'ELECTRICITE. June 29, 1939, No. 18973. Convention date, Aug. 3, 1938. [Class 109] Relates to traversing arrangements for use in coiling wires or cables on drums and to the application of such devices to collecting drums interposed between a delivery apparatus and a receiving drum. The collecting or storing device shown comprises a drum 1 for receiving wire or cable from a cable-making machine &c., a delivery drum 2 delivering the cable, say, to a receiving drum, not shown, and a connecting member 3 provided with pulleys 4 over which the cable passes from drum 1 to drum 2. The drum 1 is loose on its axis and is locked in one direction by a ratchet 7. The drum 2 is driven round an axle 9 by gearing 11, 12, the axle being driven by gearing 13, 14 and friction clutches 15, 16. The clutch 15 is driven by a toothed wheel meshing with pinion 8. The clutch 16 is also driven by pinion 8 in such a way that the axle 10 tends to drive the member 3 in the opposite direction to drum 2. The coils of cable on the drums 1, 2 also embrace rollers 5, 6 which are kept inclined to the axes of the drums. The rollers 5, 6 are mounted by means of arms 17 and pivots 18, the angle of inclination being regulated by modifying the position of the arms 17. The two pulleys 4 are each mounted on a carriage driven by a right and left-hand screw, operated by a chain 20 and sprocket 19. The sprocket 19 is integral with a wheel 21 loose on the axle 10 and is driven by a wheel 22, keyed to the axle 10, there being play from differential wheels 23, 24. The operation is as follows: The cable is first wound on the drum 1 in turns the regular spacing of which is ensured by the roller 5 and then proceeds to the drum 2, via the connecting member 3. The cable leaves the machine after being wound on the drum 2 in regularly spaced turns as determined by the roller 6. The member 3 is subjected at each movement to a couple tending to make it turn in the direction of movement of the drum 1, the couple being limited by the friction of the clutch. When the member 3 turns about the common axis of the drums 1, 2 to wind or unwind the cable on or off the drums the point where the cable leaves the drum 1 or 2 to pass over the member 3 is changed and the pulleys 4 are correspondingly displaced under the action of the gearing 22 ... 24 on the right and left-hand screw. The cable is wound on the drums in equidistant coils the distance apart of which is determined by the inclination of the rollers 5, 6 to the drums.

Title: Covering perforate metal tubes with imperforate sleeves
Inventor: BULLAS BASIL GEORGE
IPC: F16K3/26
Filed: 1962-05-17
Abstract: 993,634. Metal tubes. LABURN Ltd. May 17, 1962, No. 18999/62. Heading F2P. A method of covering a perforate metal tube with an imperforate sleeve of flexible and resilient material, the sleeve having internal dimensions equal to or slightly less than the external dimensions of the tube, includes moving the sleeve relatively to the tube over the outer surface of the tube while causing a gaseous fluid under pressure to flow between the outer surface of the tube and sleeve and allowing the fluid to escape from the end of the tube, restrictor means being provided in the tube to restrict the escape of fluid elsewhere and thus to prevent the sleeve contracting on the tube while the sleeve is being moved relatively to the tube, removing the restrictor means and causing the flow of gaseous fluid to cease, thereby allowing the sleeve to contract on to the tube. The metal tube may be of square or rectangular cross-section, and of the close-jointed kind. The restrictor means may be an element of elongated form, such as a rod, tube or inflatable bag, inserted into the metal tube to prevent any substantial flow through the perforations in the tube. The element may be such as to prevent the free flow of fluid therethrough and the fluid is fed into the sleeve from that end thereof not surrounding the tube, or through an aperture in the wall of the sleeve; alternatively, the fluid is fed into the sleeve through an element of elongated shape. Another form of restrictor means comprises a plug moved lengthwise in the tube as the sleeve is moved relatively to the tube. In a particular application, a metal rod is inserted into the perforated tube, the latter being supported by a spigot entered in one end thereof and mounted on a bench, and a plug having a frustopyrimidal head is inserted into the other end of the tube. The sleeve is drawn from a coil of polyvinyl chloride tubing wound on a drum, the inner end of the tubing being connected to a source of compressed air by way of a footoperated valve. The outer end of the coiled tubing is pushed on to the head of the plug and compressed air is admitted to the tubing as the sleeve is pushed forward over the perforated tube. The sleeve engages a vertical stop-plate on which the spigot is mounted, the air supply is cut off, and the sleeve severed adjacent the plug, the latter and the rod then being withdrawn. The rod may form a permanent extension of the spigot or the combined rod and spigot may be replaced by a tube through which air is introduced, the plug then having an axial hole and means being provided to prevent air escaping from the inner end of the coiled tubing. Specification 993,633 is referred to.
