Title: Improvements in or relating to the manufacture of corrugated metal tubes
Inventor: HICKS LEONARD
IPC: B21D15/06
Filed: 1957-09-11
Abstract: 891,124. Corrugating tubes. POWER AUXILIARIES Ltd. Sept. 1, 1958 [Sept. 11, 1957], No. 28700/57. Class 83 (4). A method of deforming the wall of a seamless or seam-welded metal tube into contact with a suitable shell mould to produce an annular corrugation comprises introducing axially into the tube a tool mandrel containing a suitable deforming cam withdrawn within the inside diameter of the tube, rotating said mandrel relative to said tube or vice versa while forcing said cam outwardly to deform the wall of the tube until a predetermined position of maximum penetration is reached, and thereafter jointly rotating the mandrel and cam relative to the tube or vice versa until a complete annular corrugation of a profile corresponding to such maximum penetration has been produced and then withdrawing the cam to its original position to permit axial displacement or removal of the mandrel. A tube 1 is inserted into a twopart die 2, 3 formed with internal corrugations 5. A mandrel 8 is then inserted into the tube and rotated so that a cam member 12 accommodated in a transverse slot 10 therein is urged outwards, by frictional engagement with the tube and/or by gear means 17, 18, until it strikes a stop surface 14 on the mandrel. Subsequent rotation of the mandrel causes the cam member 12 to form an annular corrugation 7 in the tube. Thereafter the cam member 12 is retracted by reversing the rotation of the mandrel and/or by the gears 17, 18, the die 2, 3 is opened and the tube 1 is moved downwards so that the corrugation just formed is accommodated in the next internal corrugation of the die 2, 3 which is then closed. A further corrugation is then formed by the cam member 12.

Abstract: 767,159. Brakes for hand-propelled vehicles. SAGE, H. F. G. Sept. 21, 1955 [Oct. 11, 1954], No. 29239/54. Class 103 (1). In a locking device for the wheel of a perambulator or like hand-propelled vehicle, a rotor member rotatable with the wheel and having one or more recesses in its circumferential surface, is adapted to be locked by an interlocking plunger mounted non- rotatably on a stator member by a control device operable from the handle of the vehicle to disengage the interlocking mechanism. In the embodiment illustrated, one or each of the rear wheels 14 incorporates a locking device 18 which is controlled automatically by a handle-bar device 15. The locking device 18 comprises a stator 19 fixed to the non-rotatable axle 12. An L-shaped bracket 22 is attached to the stator and carries the lower end of the sheath 25 of a Bowden cable control; the cable 26 of which is attached to the upper end of a locking plunger 27 which is slidable through holes'provided in the circumferential wall 20 of the stator 19 under the action of compression spring 32. A cup-shaped rotor member 37 having an outwardly projecting hub flange 38 for attachment to the wheel spokes 39, is provided with a series of holes 41 which which are disposed in line with the plunger 27 and adapted to receive the bolt portion 28 of the plunger 27 whenever the Bowden cable 26 is released. The handle-bar device 15 is arranged to control the Bowden cable 26 and comprises a transverse front rod 42 and a transverse rear rod 43. The former is attached in ballbearing 44 which acts as a fulcrum for rocking levers 45 ; the rear ends of which are rigidly connected to the rear rod 43, the forward end being attached to cable 26 of the Bowden mechanism. Thus, whenever the hand pressure is removed from the rear rod 43,'the spring 32 brings the plunger 27 into its locking position automatically to prevent accidental movement of the perambulator in forward and rearward directions.

A method of producing hardened wire or strip coils of cylindrical helical conformation comprises the steps of helically winding the wire or strip in a cold state on a cold mandrel C having a free end from which the coil B is continously discharged, passing the cold coil B as it travels away from the mandrel C through an oven D and applying thereto a hardening temperature, and instantly quenching, e.g. by liquid from a nozzle H, the heated coil on its emergence from the oven D. The coil may then be cut into lengths by a cutting wheel M swingable to and from the coil on a reciprocating carriage K. The lengths may then be transferred to a tempering oven. The coil B passes through the oven D through a tube E heated by a gas burner F.
