Title: Improvements in or relating to raking devices
IPC: A01D78/16
Filed: 1955-02-22
Abstract: 804,344. Side-delivery rakes. VAN DER LELY N.V., C. Feb. 22, 1955 [March 5, 1954], No. 5330/55. Class 6(3). A side-delivery rake comprises a main frame carrying horizontal axles 5, 6, 7, 8 with a driven rake-wheel on each axle, the circumference of the rake-wheel having teeth which are capable of deflection on encountering the ground or crop but means are provided to maintain the teeth, after deflection, at a suitable orientation for raking. The frame consists of two units composed of tubes 13, 14 and 15, 16 welded together at right angles and carrying bearings 9 for stub axles 5, 6, 7, 8, each axle being integral with a rake-wheel 1, 2, 3, 4. Each unit includes a castor 23 which drives one of two rake-wheels through a universal joint, Fig. 4 (not shown), a shaft 62 and bevel-gears 58, 60, the other rakewheel of the pair being driven from the first through chain-gearing 56. The swivel axes of the castors are lockable by pins inserted through mating flanges 46, 47 or they may be swingable with a pivoted drawbar 33 through connections 48, 50. The drawbar is pivoted to an inverted U-shaped member 31 interconnecting the units which may be swung around to form two parallel rows, for swath-turning. The drawbar carries lugs 38 which engage springs 39 encircling a fixed loop 36, the springs being anchored by a pin passed through one of several holes in the loop. The rake wheels each comprise a disc 72 with spokes 78 extending outwardly tangentially to support, coaxially, a rim 79, the spokes passing therethrough and terminating in short teeth 80. Steel wires 77 also extend between the disc and the rim and are bent back twice, at 81, 82, before terminating in short teeth 83. At the second bend 82 each wire has a loop through which passes an endless, sinuously-coiled wire 84. The wires are readily deflected out of their wheel-plane by torsion of the parts 77 but the wire 84 prevents too great a separation occurring between adjacent teeth, so that the portions 83 always remain parallel to their original direction. Specification 804,345 is referred to.

Title: Improvements in the production of sheet metal cylinders, drums and like containers and in apparatus used therein
IPC: B21D51/20
Filed: 1925-02-27
Abstract: 243,947. Giles, A. C., and Tanks & Drums, Ltd. Feb. 27, 1925. Hollow - warc. - Longitudinally corrugated metal cylinders, drums &c. have their ends flattened in regular folds in order that the heads may be jointed liquid-tight to the bodies without the use of solder. A sheet metal cylinder formed in the usual way is passed between dies 2, 3, Figs. 7 and 8 of which the lower die 3, is fixed upon a rubber &c. support 8 while the upper die 2 is reciprocated vertically, adjustment being effected by a wedge 6. The first stroke of the upper die corrugates the whole length of the cylindrical body except for a small portion between flattened parts 2a, 3d of the dies; the body is then fed forward one corrugation at a time so that the ends of the corrugations come successively between the flattened portions 2a, 3d, a rib 3b of the lower die being shaped as shown so that the flattening is gradual as indicated in Fig. 1. When all the corrugations have had their ends flattened except the last two a part 3c of the lower die of corresponding width to the flattened portions 2a, 3d is slid sideways into an inoperative position so that the flattened ends are not again corrugated, and the blank is then fed forwards to complete the flattening. The head is seamed on and a hoop 10 arranged as shown in Fig. 11. For producing bilged barrels the dies may be curved.

Abstract: 487,802. Fluid - pressure brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and GATES, G. R. G. Feb. 25, 1937, No. 5725. [Class 103 (i)] The piston or pistons of a hydraulic brake operating cylinder are adapted to be operated by auxiliary mechanical means which act within the liquid space of the cylinder. In Fig. 3, the pistons 12, 13 which engage the shoes 14, 15 of an internal expanding brake have projections 31, 32 with inclined ends engaged by rollers 39 carried by a rod 24 slidable through a gland 25 in the wall of the cylinder 11 which is secured to the back plate 10. To ensure efficient rolling action of the rollers three are employed mounted on a common pin, the upper and lower ones bearing only on the inclined end 38 and the middle one of larger diameter only on the end 37 and being accommodated in a groove in the end 38. Washers 46 are interposed between the packing caps 45 and the pistons and passages 47 permit entry of air between the washers and pistons when these are moved by the mechanical means. Toggle links may replace the wedge device shown. In Fig. 1, projections 31, 32 on the pistons 12, 13 have helical cam surfaces 29, 30 engaged by similar surfaces on projections 27, 28 on a disc 21 adapted to be turned by a rack 23 slidable in the upper part of the cylinder and formed on a rod extending through the wall. The pistons engage caps 18, 19 slidable on the cylinder ends and prevented from rotation by engagement of slots with projections 17 on the cylinders, pins 20 preventing rotation of the pistons. Adjustment for wear of the brake linings is effected by rotating the head 34 on a stem 35 screwed into the piston 13. The rack 23 may be replaced by a worm which is turned to operate the pistons. When the cylinder has a single piston the mechanical means may be operated through the closed end thereof. According to the Provisional Specification the mechanical means may comprise a cam interposed between the two pistons, the cam spindle extending transversely through the cylinder wall.
