Pins for cottering.- For securing a bolt, stud, pin, &c., a locking member is employed which passes through or engages the end of the part to be secured and is rotated about its axis and thereby stressed to effect the lock. Figs. 2 and 3 show the application of the locking pin or member to a bolt. The pin a is bowed and passes through a bore f in the bolt. It can be rotated by a crank arm c from the unlocked position, Fig. 3, to the locked position Fig. 2, which is beyond the dead centre position where the pressure between the bow b and the top of the bore f is a maximum. A lip d on the end of the arm c may engage a hole in the bore to prevent longitudinal movement and relative rotation of the bolt and work. or the arm may be curved to engage the wall of a recess in the work. In a modification, the bowed pin engages two bolts, the crank arms being arranged between the bolts. In another arrangement, the pin engages holes in lugs and can be brought to bear upon the head or end of a bolt &c. located between the lugs.

[Class 83 (iv)] [See also Group V] The extrusion chamber of a device for sheathing cables with lead is arranged vertically, molten lead being delivered to the upper part of the chamber by a continuously operating screw pump and solidifying during its passage therethrough, and the cable passing downwards through the chamber and the die. Molten lead passes from a vessel through pipes leading to screw pumps 16, 17, by which the metal is driven through a chamber 33 and between the die and counter-die 38, 36. The metal is heated adjacent the pumps by an electric heater 55, and is cooled and solidified during its passage through the press chamber bv coolant in channels 57. Thermostat contacts for automatic control of the temperature may be inserted in pockets 59. The die 38 is supported and centred by wedges 46 controlled by nuts 49 on screwed portions 48, a ring 44, and a ring 50. A ring 37 bears on the die 38. A screw pump, which is described in Swedish Specification 74,114, comprises worms 61, 62 with threads of opposite hand mounted on a common shaft and disposed one on each side of an outlet channel 34, further worms 63, 64 and 65, 66 co-operating with the worms 61, 62 respectively. The cable 20, Fig. 1, enters the press 10 after passing over a roller 21, and, after leaving the press, passes over a roller 22, and is drawn off in a horizontal direction. In a modified form of press a single pump is employed having a hollow driving screw through which the cable passes. According to the Specification as open to inspection under Sect. 91, the apparatus may be employed for the manufacture of rods and tubes, and for the extrusion of materials, other than metals, having organic or inorganic constituents. The press may be arranged horizontally. This subject-matter does not appear in the Specification as accepted.

Abstract: 533,277. Clutches. MAGNAGHI, E. Oct. 26, 1939, No. 28770. [Class 80 (ii)] [Also in Group XXVIII] The cylindrical body 5 of a pump comprising pistons 6 reciprocating in cylinders in the body 5 under the action of a swash-plate 10 is driven by a rotary shaft 1 formed with a frictional conical bell 4 into contact with which a conical part 17 of the body 5 can be brought by means of a cam 21 on a lever 20 which can displace a plunger 18 to the left against the action of a spring 19 and thus permit the body 5 to move to the left under the action of springs 11 which are normally overcome by the action of the spring 19. On release of the lever 20 the pressure of the fluid acts to maintain the clutch elements 4, 11 in engagement. The liquid enters via a pipe 12 and suction conduit 13 and is urged into the pressure conduit 14 connected by a non- return valve 16 to the outlet pipe 15. In the position shown a groove 24 in the rod 18 connects the suction and outlet sides of the pumps so that the clutch elements do not engage. The outlet 22 is closed by the solid part of rod 18 when this rod is moved to the left.
