Title: Improved machine for moulding and vulcanizing articles of footwear
Inventor: VDOLEK VLADIMIR
IPC: B29C35/00
Filed: 1956-10-23
Abstract: 831,092. Moulding footwear. BRITISH BATA SHOE CO. Ltd. Oct. 23, 1956, No. 32245/56. Class 87(2). Shoe soles are moulded on to uppers by placing the uppers on lasts 19a, Fig. 3, removing moulded soles on lasts 19 along tracks 74 and then moving the lasts 19a along tracks 73 into the moulding position. In operation low pressure fluid is supplied to a cylinder (see Fig. la, not shown) causing a beam 21 to be lowered. As the beam moves downwardly, links 50 are moved inwardly causing (a) members 17 to move the lasts 19 against a central side mould member 2, and (b) side mould members 11, 11a to be moved against the lasts 19. When a shoulder 64 engages a flange 40, further inward movement of the lasts and side mould members is stopped. High pressure fluid is then supplied to the cylinder to cause the top mould members 55 to be moved down against springs 47 to close the mould cavities. The rubber is then vulcanized by electric heating elements or a high frequency system. A thermostatic control 78 may be provided. Thermal insulation e.g. as shown at 66a, may be provided between all the mould members and their supports. After a predetermined time, the machine is opened by automatic time control, the beam 21 first lifting the moulds 55 and then moving the side moulds 11, 11a outwardly and then, when a dog'53 has moved along a slot 18, the lasts 19 are moved away from the central side mould member 2. The lasts with the moulded shoes are then removed along the track 74. The mould members are provided with overflow passages 70a, (706, not shown) 70c, 70d and overflow chambers 69a, (69b and 69c not shown) and 69d. The size of the overflow passages is arranged to be such that the resistance of the rubber in the passages prevents the pressure developed in the mould from being reduced.

[Also in Groups XIII, XXIX and XXXII] Differential pressure responsive apparatus, particularly for use in a fluid flow meter, comprises two chambers 28, 30 adapted to receive fluid under different pressures, bellows 52, 54 whose interiors are filled with liquid and connected by a passageway 68, a control spring 76 connected to the closed end of the bellows 54 and extending away therefrom perpendicularly to the axis of the bellows, and a device 74 for indicating externally the movements of the bellows 52, 54. The spring 76 (Fig. 3) is formed of a pair of spiral elements 76a, 76b each fastened at its outer end to the body of the apparatus and at its inner end to a shaft 74 connected to the bellows end plate 66. In order to vary the range of the flow meter the spring 76 is replaced by a similar spring having a different rate. Fig. 4 shows a device used to provide temperature compensation. It consists of a pair of cross-shaped elements 106, 108 having their outer ends joined by straps 110. The inner ends of these elements are connected respectively to the last convolution of the bellows 52 and to the bellows end plate 64. The elements 106, 108 have different coefficients of thermal expansion and thus a rise in temperature opens out the end convolution of the bellows 52. The construction of the bellows 52, 54 is shown in Fig. 6. Pairs of diaphragms 82, 84 are secured together alternately at their inner and outer ends, support rings 90 being provided to prevent damage to the bellows on occurrence of high pressures in the chambers 28 or 30. To prevent wrinkling of the bellows under these conditions, the diaphragms are so shaped that spaces 92, 94 are formed when the bellows collapse. Also described, Figs. 7 and 8 (not shown), is a third bellows to act as a seal where the movement indicating rod 80 passes through the wall of the liquid-filled space 72 contained by the bellows 52, 54. The movements of this rod are recorded by a conventionapen-recorder. The flow of liquid between the interiors of the bellows 52, 54 is damped by a plug 120, the position of which can be manually adjusted. Specifications 790,294 and 843,145 are referred to.
