Title: Method of making foundry moulds and apparatus therefor
IPC: B22C17/00
Filed: 1973-09-10
Abstract: 1450431 Foundry moulding SHEBWIN WILLIAMS CO 10 Sept 1973 [10 Oct 1972] 42520/73 Heading B3G In a method of making a sand mould, a mould box is formed by positioning a movable bottom wall 62 and a movable side wall 61 against a fixed top wall 46 and a fixed side wall 60, positioning squeeze heads provided with patterned surfaces to form opposed end walls of the box, filling the formed box with sand, ramming the sand with the squeeze heads to form the sand mould with the patterned surfaces impressed therein, opening the box by retracting the heads from the mould, and moving walls 61, 62 diagonally away from the wall 40, 60. After the diagonal movement, the walls 61, 62 are moved horizontally to convey the sand mould to a position in alignment with a horizontal bed along which the mould is pushed. A horizontal stack of moulds is thereby formed on the bed, and the stack is moved stepwise thereon past a station where molten metal is cast into the mould cavities formed between juxtaposed moulds. The walls 61, 62 are mounted on a carriage, not shown, and moved horizontally on rails, not shown, towards and away from the fixed walls, by an hydraulic piston and cylinder assembly 65 acting through pivoted toggleaction linkage means 74, 78. On closing the box, cam rollers 86, 87 on the carriage engage fixed cams 88, 89 causing a diagonal upward movement see arrow 243, Fig. 12, of the walls 61, 62 to effect final closure movement; on retraction of the walls, Fig. 14, a diagonal downward movement, precedes the horizontal movement. With the mould box closed, a sand reservoir located above it is filled with sand which is then blown into the box via a slot in its fixed top wall. After the sand pressing operation in which the squeeze heads are driven by opposed hydraulic piston and cylinder devices and vibrated, the heads are withdrawn from the box which is then opened and the mould conveyed to a position in front of an hydraulically driven pusher which transfers the mould to a bed along which it is conveyed. Such conveying means forms the subject matter of the divisional Specification 1,450,432.

Title: Device for separating rubber and textile fibres from their bonded mixture
IPC: B29B17/00
Filed: 1961-12-11
Abstract: 980,698. Rotary sieves. H. A. MERGES. Dec. 11, 1961 [Dec. 10, 1960], No. 44310/61. Heading B2H. An apparatus for the separation and classifying of fibres and grains of bulk material such as pre-crushed mixtures of rubber and fabric from vehicle tyres comprises a rotary sieve drum having sections of different mesh size, and a relatively rotatable shaft within the drum and provided with rods radially extending from helical lines on the shaft into spaces between rods extending radially inwardly from the longitudinal periphery of the drum, the drum rods being substantially equal in length in the sections near the input end and progressively shorter and spaced further apart in succeeding sections; and the drum having a truncated conical or pyramidical end section with spaced comb-like rows of teeth on its inner longitudinal periphery, a baffle and discharge shoot. In Fig. 1 hexagonal sectioned drum 1 drawn by motor 2 is arranged to rotate in a direction either opposite to shaft 5 driven by motor 6 or in the same direction but at a different speed. The mesh size on the drum longitudinal walls is progressively larger away from an input shoot 9. In operation bulk material is fed in through shoot 9 and the combing and beating effects of the drum rods 3 and shaft rods 4 at the input section where the rods are densest is said to separate the components of the material, some of the rubber particles passing through the drum mesh to discharge shoot 12. The remaining material passes to the succeeding sections and the process is continually repeated, the rubber particles according to size passing through the mesh and down shoots 13-16 where they are carried away preferably by pneumatic suction means. The truncated conical end section, Fig. 1 (and Fig. 2, not shown), has equispaced combs 8 which take up the fabric fibres and drop them on to a baffle 10 which in turn deflects them through a discharge shoot 11. The shaft rods 4 may be resiliently flexible so that they can be bent back by the bulk material and then beat with increased force or stops may be provided on the drum for the bending process. Alternatively the shaft 5 may be eccentric to the drum's rotational axis or it may be cranked. Instead of radial rods the drum and shaft rods may be inclined to a radius.

A clamping device comprises a rail 1 adapted to be attached to a supporting surface, a plurality of clamping elements 2 slidably mounted on the rail to engage parts 3 to be clamped, the rail being T-shaped in cross-section with a web and flange projecting therefrom, each clamping element having a corresponding T-shaped slot with re-entrant flanges underlying the flange on the rail, the slot permitting sliding and tilting of the element on the rail, and the rail and clamping elements having interengaging pawl and detent members 17, 8 adapted to slide over each other in one direction to press the elements against the parts to be clamped and to engage each other by tilting movement of the elements. As shown, the slot in each element has non-parallel upper and lower surfaces to permit the tilting movement which in a clamping operation is effected by a tool inserted between teeth on the head of the rail pawl. The elements are released by pressing their upper ends together; inadvertent release of the clamped parts is prevented by securing members 20 mounted on the rail.
