Title: Improvements in or relating to the manufacture of composite belts and apparatus therefor
IPC: B29D29/00
Filed: 1948-11-30
Abstract: 670,503. Belt gearing. GOODRICH CO., B. F. Nov. 30, 1948 [Jan. 31, 1948], No. 31023/48. Class 80 (i). [Also in Group VIII] A composite belt of rubber-like material and parallel reinforcing tension elements such as cords, wires or cables is made by progressively feeding together two groups of spaced-apart parallel tension elements, with the elements of one group intercalated with those of the other group, simultaneously feeding plastic sheet rubber-like material between the groups and pressing it against the said elements, while forcing the latter into alignment of their axes in a single plane by pressure applied to the assembly uniformly across its faces, and simultaneously working the plastic material into intimate contact throughout their outer surfaces with the tension elements. Plastic sheet rubber-like material may be applied to the opposite faces of the material so produced to enclose the tension elements. Two groups 62, 63 of tension elements are drawn from sets of braked spools 20 mounted on pins 21 on creel frames mounted on the stantions 13, 13' and 17, 17<SP>1</SP> respectively. They then pass through dipping tanks 25, 37, where they are coated with rubber cement or other coating material, and through drying ovens 35, 45, being guided by rollers 27, 28, 29, 26, 30, 36 and 39, 40, 41, 42, 43, 44 respectively, and through comb boards 55 or 56, and, together with an interposed sheet of rubber-like material 61 from a roll 60, pass into the nip of the rollers 50, 51, which is adjustable by handwheels 54. Sheets 66, 67, of rubber-like material one or both of which may contain fabric reinforcement, from rolls 111, 140, are applied to either face of the composite sheet, and the whole squeezed together by a pair of rollers 52, 53. The edges are trimmed between a driven roller 68 and adjustable circular cutters 69. The sheet passes under a vertically-movable counterweighted roller 79 to a wind-up reel 88 on a carriage 82; the roller 79 carries a sheave 86 which rests on the driving-belt 83 of the wind-up reel 88, and is raised, permitting the belt to slip, when the tension of the sheet increases. A wind-up reel is provided for the liner 100, removed from the sheet 61, comprising a driven roll 102, rotating in contact with a roll 109 of the liner. A similar wind-up 110 is provided for the liner 120 which is stripped from the sheet 66 as it passes under a weighted roller 114, which is guided in vertical slots in the stantions 113. A limit-switch 130 is actuated, and causes the drive to the liner wind-up to be engaged, if the pull of the sheet 66 and action of a brake 132 acting on the sheet roll 111, causes the roller 114 to rise into contact with it, a lower limit switch 131 being provided for disengagement of the drive. A wind-up comprising a driven roller 141 in contact with a roll of linen formed on a mandrel 146, is provided for the liner removed from the sheet 67.

Abstract: 439,329. Cabinets. ROBINSON, F., and BETTS, C. 1., 39, Earl Street, Maidstone, Kent. Oct. 30, 1934, No. 31030. [Class 52 (i)] [See also Group VI] One wall of a food safe, cupboard or like container, comprises a flexible metallic permeable member which is slidable in guideways formed in other parts or walls of the safe, to open and close the container. The flexible wall may be made of perforated sheet metal, e.g. zinc, or may consist of a number of lengths of wire 25, Fig. 7, secured together by flexible binding wires 16. The flexible wall may be arranged to be wound on a spring roller, but as shown in Fig. 2, the flexible wall 1 slides in guides 5, over a roller 8 and between the top 4 of the safe and an inner false top 6 which is flanged at its lower end to be secured in a channel 7, e.g. by soldering. The free edge of the flexible wall may be secured to a counterweight, but as shown it is simply beaded at 18 to prevent it from catching against the walls of the safe. The lower edge of the wall 1 is stiffened with a transverse strip, the ends of which project into the guides 5. Battens 11 and 12 also are secured to the lower edge of the wall 1 and rest on the floor of the safe when it is closed. The outer batten 12 may have a lip or flange 14 to extend below the floor level. Alternatively, a groove may be provided in the floor to receive the flange 14 or other downwardly extending part of the wall 1. A lock may be provided on the lower edge of the wall, and a finger piece 15 is also fitted. The top 4 of the safe may be flat, and two rollers 8 provided to guide the wall. The flexible wall may form only a part of the front wall of the safe, the remainder of the wall being a rigid structure. The wall may be arranged to move laterally.

Abstract: 733,298. Mincer. KROTZ, A. Nov. 10, 1953 [March 28, 1953; April 17, 1953], No. 31131/63. Class 28 (2). The annular rotated meat trough 56 of a mincer is provided with two or more overhung cutter shafts. Each shaft has an external sleeve rotated in the opposite direction from its concentric core shaft and also carries cutters which create a scissors like action with the blades of its concentric cutter. The cutters however may rotate in the same direction. The spacing of such co-operating cutter sets may vary from 0 to 2 millimetres for fine cutting to 10 to 30 millimetres for coarse cutting. One of the cutter sets in the trough may be adjusted for rough cutting, the other set being adjusted for subsequent fine cutting. Fig. 2 shows at its lower half several cutters 10, 11 mounted on a neck 8 widely spaced from oppositely rotated co-operating cutters 23, 24. The neck 8 is externally hexagonal to receive the forked end 13, Fig. 7, of the cutters 10 and 11 thereby allowing the cutters to be spaced like radii on the shaft 1. (The cutter 12, Fig. 7, is a special cutter with a lug 42 for peripheral cutting.) The cutters 10 and 11 are secured by a screwed on or pressed on clamp ring 15 secured by a grub screw 16. The cutters 23, 24 likewise secured on the neck 26 of a hub 17 having dogs, or radial grooves or keys 18 to receive the drive from the outer shaft 2. The upper half of Fig. 2 shows alternative closelyspaced cutters 33, 37 of the shape shown in Fig. 8 secured by countersunk screws 34 on flanged rings 32 and 36 respectively. Such cutters are suitable for cutting meat tendons, and have co-operating cutting edges 38, Fig. 9. To avoid adjustment of the cutters various sets of cutters are mounted on various sleeves 5 and-35 respectively so that the sleeves can be slid on and off their drive shafts 1 and 2 and clamped thereon by nuts 30 and 19 respectively. Fig. 5 shows a number of cutters 12 with spacers 43 similarly mounted on the inner shaft 1 there being no co-operating cutters on the outer shaft 2. The various cutter assemblies may be driven at different speeds by different independent motors 40 (Fig. 4, not shown), or one or more assemblies may be stationary. The bowl trough may have a motor for independent rotation at any selected speed.
