Abstract: 305,118. Lambert Tire & Rubber Co., (Assignees of Brundage, J. W.). Jan. 31, 1928, [Convention date]. Moulding wheel tyres.-In tyre moulds having core pins adapted to form transverse holes in the tyre tread, the pins are secured to and are advanced and retracted by a spider connected to a piston working in a cylinder mounted upon the mould. The invention is shown applied to a watch-case vulcanizer comprising a central stationary section 1 carrying half-mould shells 33 co-operating with mould shells 43 carried by doors 20 hinged to the section 1 and adapted to be secured thereto by locking rings 9. Each shell 33 is interchangeably positioned by seatings 28, 29 on the part 1 and is secured thereto by screws 32. Similar seatings 30, 31 on each door 20 locate the co-operating shell 43 which is. embraced by a flange 38 on the shell 33. Core pins 64 pass through tubes 58 which also reinforce the shell 43. The tubes are formed with a screwed portion 56 engaging recesses 55 in the shell and with shouldered portions 59 abutting against the door against which they are clamped by nuts 62. The forward ends of the pins 64 are adapted to engage recesses 42 in the shell 33 and their rear ends are secured to a spider 67 connected by a thread 81 to the rod 79 of a piston 78 working in a cylinder 71 bolted to the door 20 and furnished with fluid connections 74, 75. A yoke 85, bolted to the door 20, guides the spider 67 and is also bored at 86 to receive and guide an extension 82 of the rod 79, inward movement being limited by a stop flange and nut 84. Each locking ring 9 is located upon a flange 8 and is furnished with a lubricating groove 11. Hooks 12 on the ring carry wedges 13 adapted to engage corresponding wedgemembers 24 on the door 20. The ring is turned through a fluid cylinder and piston connected to a lever on the ring or through a pinion engaging racks on the ring and on the stationary member 1. In use, a built-up tyre carcass fitted with an air bag is placed within the mould and the latter closed, the core pins being withdrawn. Suitable air pressure is applied to the air bag and after sufficient time has elapsed to soften the rubber the core pins are advanced and left in this position until curing is finished. The pins are then retracted and the mould opened for removal of the finished tyre.

Patent GB-369097-A (GB)
Title: Improved manufacture of olefin-polysulphide plastics
IPC: C08G75/16
Filed: 1931-06-18
Abstract: A plastic body is obtained by incorporating a protective colloid with a dispersion of an olefine polysulphide, preferably during the formation thereof.  To obtain the dispersion of the olefine polysulphide, a finely divided, insoluble basic compound of an alkaline earth (such as a hydroxide, oxide or carbonate of calcium, barium or magnesium) may be incorporated with the mixture of olefine compound and polysulphide, and the protective colloid, preferably a protein, may be incorporated with the reaction mixture or dispersion. On coagulation of the dispersion, the protective colloid remains with the plastic.  The polysulphide employed may be the polysulphide of an alkali, alkaline earth, ammonium or organic base, such as triethanolamine and the quantity of sulphur therein may vary from twice that in the normal sulphide up to the maximum, usually S5.  In an example, a polysulphide is reacted with an olefine compound such as ethylene dichloride in presence of the dispersing agent such as magnesium hydroxide and the protective colloid, such as egg albumen. The magnesia may be added as magnesium chloride, preferably with the addition of a little alkali.  The ethylene dichloride is preferably added last, in small quantities and under a reflux condenser.  The final temperature of the mixture may be 190-195 DEG  F.  The latex produced may be washed by decantation with water.  To coagulate the latex, it is first neutralized with an acid such as sulphuric or hydrochloric acid, washed with water by decantation, and flocculated by addition of a dilute alkali such as soda, potash or ammonia. Instead of egg albumen other colloids may be used, such as glue, casein, blood albumen, gelatin, hydrolysed starch, gums, dextrin, saponin and the like; and instead of ethylene dichloride there may be used formaldehyde, hexamethylene tetramine, a methylene dihalide, or a dihalide of a higher olefine such as propylene, butylene or amylene.  The coagulated product may be milled in a rubber mill with compounding materials such as zinc oxide, carbon black, litharge, stearic acid, clay, &c., yielding a plastic and tacky mass which on heating to 212-300 DEG  F. under pressure becomes resilient, tough and elastic having insulating and dielectric properties and insoluble in oils and organic solvents.  It may be extruded in its plastic form to form tubes or the covering on electric conductors and may be pressed upon cotton, duck, or asbestos fabrics, being heated subsequently to harden the material.  Reference has been directed by the Comptroller to Specification 359,000.
