Title: Improvements in machines for moulding plastic material, for exampleí¬butter
IPC: A01J21/02
Filed: 1949-10-22
Abstract: 674,005. Positive clutches. BRECKNELL, MUNRO & ROGERS, Ltd., and LAWSON, C. W. Jan. 22, 1951 [Oct. 22, 1949], No. 27164/49. Class 80 (ii). [Also in Group V] In a machine for moulding plastic material such as butter (see Group V) a main shaft 31 is first driven and then motion is transmitted to an auxiliary shaft 48 without undue shock and yet so that the parts driven by the auxiliary shaft are set in motion in correct phase relationship with those driven by the main shaft. A drum 90 of disc form is secured to the auxiliary shaft 48 and a'plate 91 is secured to the main driving shaft 31. The plate 91 carries a pair of brake shoes 92, 93, Fig. 8, pivoted thereto on a pin 94. The brake shoes are moved apart to expand against the inner periphery of the drum 90, by a wedge 97 moved radially outwards, the movement overcoming the tension of springs 109. The wedge 97 carries a pin 96 screwed into it, and this pin is forced outwards when the tapered end of a pin 194 moves forwards, the movement imparted to the wedge being adjustable by screwing the pin 96 in or out. The pin 194 is carried by a sleeve 99 that can be slid along the shaft 31 by the movement of a handle 100. In the drum 90 is a disc 108 in which is a shallow arcuate groove 106, Fig. 7, subtending an angle of about 90 degrees, its depth increasing from zero at 116, till it ends in a hole 107. When the brake shoes 92, 93 have expanded to their furthest extent by the forward movement of the pin 194 the end of this pin meets the end 116 of the groove 106, and after about 90 degrees lost motion the pin 194 enters the hole 107 and the drive from the shaft 31 to the shaft 48 becomes positive and in correct phase relation. The positive clutch action is strengthened by additional pins 110, 111 carried by the sleeve 99. and co-operating with grooves 112, 113 and holes 114. 115. The grooves 112, 113 are of different radius from the groove 106 so that positive drive can be established only when the parts 90, 91 are in correct phase relation. The resisting torque to be overcome by the shaft 48 may be a variable quantity, and the greatest driving torque that can be applied by the friction brake shoes must therefore be adjusted, by screwing the pin 96, to ensure that the whole of the lost motion will be taken up before the shaft 48 has been driven for any considerable period of time in the wrong phase relation. Specification 672,742, [Group V] is referred to.

Abstract: 906,797. Rubber-coated fabrics. DU PONT DE NEMOURS & CO., E. I. Aug. 10, 1960 [Sept. 1, 1959], No. 27687/60. Drawings to Specification. Class 140. Rubber-coated fabric sheet material suitable for the production of grooved diaphragms is produced by applying a layer of uncured rubber composition to at least one side of a fabric, pressing the thus-coated fabric while heating it to curing temperature for a period of time sufficient to cure the rubber layer partially to 50 to 90% of full cure, whereby the fabric is anchored against under movement relative to the plane of the rubber layer when grooved diaphragms are subsequently moulded from the partially cured sheet. Both sides of the fabric may be coated with a layer of the rubber composition, the two layers being of approximately equal thickness. The uncured rubber-coated fabric may be continuously and uniformly pressed and heated in a moving arcuate pressure zone formed between the cylindrical surface of a heated rotating drum and an endless pressureband looped about a major portion of said surface and moving therewith. Flexible diaphragms having an annular groove in the intended region of flexure may be made by simultaneously pressing and heating the partiallycured sheet material in a grooved mould at a pressure, temperature, and for a period of time sufficient to cure the rubber coating fully. The rubber composition may comprise a natural or synthetic rubber, e.g. butadiene-styrene copolymer, and may contain a sufficient amount of free sulphur to cure it fully; the pressing and heating of the uncured rubber-coated fabric being carried out so as to cause 50 to 90% of the sulphur to react with the rubber, based on the weight of sulphur needed to cure the coating fully. The rubber coating may also contain polyvinyl chloride. A primer coating, which may contain butadiene-acrylonitrile copolymer, phenol - formaldehyde and paracoumaroneindene resins, may be applied to the fabric which may be a woven cotton or nylon fabric, non-woven, or open weave fabric made from fairly heavy threads. The surface of the coated sheet material may be dusted with mica and/or a synthetic wax.
