Patent GB-777015-A (GB)
Title: Improved method of forming hollow articles from sheet metal blanks
IPC: B21D22/16
Filed: 1955-08-31
Abstract: 777,015. Making hollow ware, wheel discs; spinning; altering physical structure. LODGE & SHIPLEY CO. Aug. 31, 1955 [Sept. 9, 1954], No. 25067/55. Classes 83 (2) and 83 (4). A method of forming hollow articles which have sides of tapering thickness by displacing metal of a blank comprises supporting a blank on a spindle defined by a curved surface of revolution and while the spindle and the blank are rotating, making a roller having a working tip in contact with the blank to displace metal of the blank and making said working tip follow a path having the same curvature as the curve defining said surface, the path being non- parallel to said surface and displaced therefrom in a direction parallel to the axis of the spindle by a distance substantially equal to the original thickness of the blank to axially displace metal of the blank and thereby form a hollow horn or bow-shaped article whose side is of tapering thickness. In an embodiment for making automobile wheel discs a flat or cupped metal blank 1208 is held against the flat portion 1207 of a dome-shaped spindle 1204 by a tail stock 1209. The blank is rotated and a roller 1220 starting from a point 1221 follows a working curve 1222 which is identical to the surface curve 1206 of the spindle and axially displaces the metal of the blank to conform with the spindle and reorientates the grain structure. Thus the thickness of the formed sides measured parallel to the axis of rotation remains equal to the original thickness of the blank while the thickness measured normal to the spindle surface gradually decreases. The surface cuve of the spindle may be tangential to the flattened end portion (Fig. 3) or intersecting (Figs. 4 and 6) or the curve may be such that a uniformly decreasing taper is imparted to the side of the formed hollow member (Fig. 5). In another embodiment the spindle is provided with a curve 1247 having a radius of curvature which decreases as the curve goes away from the axis 1250 of the spindle (Fig. 7) so that the side thickness of the formed hollow article has a taper gradually increasing towards its mouth. A plurality of rollers may be used and the head of the spindle may be pointed. The thickness of the blank may be non- uniform, e.g. the portion clamped between the spindle head and tail stock may be thicker than the remainder of the blank.

Title: Apparatus for supporting and raising working platforms used in building
IPC: E04G1/20
Filed: 1944-12-14
Abstract: 591,596. Scaffolding. BRADBURY & SONS, Ltd., J., and POWELL, A. D. Dec. 14, 1944, No. 25102. [Class 20 (ii) ] Apparatus adapted to raise and support working platforms used in building or the like comprises a tubular steel scaffolding standard 5, a platform carrier or guide 1, guide retaining means 2 and guide jacking means 3. The guide comprises a tube 4 which slides on the standard 5 and has a plate 11 welded to it, to which plate a ledger is attached by the U-bolts 12. The guide retaining means comprises a gripping plate 9 tiltable on trunnions which are mounted in a pair of depending lugs 8, one lug being an extension of the plate 11 and the other being on a plate welded to the lower end of the tube 4 opposite the plate 11. When the plate 9 is tilted its jaws 9<1>, 91, which are rigid, engage diagonally opposite points of the standard 5, and it is held thus by the pressure of a spring 14 on the arm 15 rigid with it. The plate 9 can be brought level, and so freed from the standard, by raising a lever 18, so causing a roller thereon td engage a cam profile 17 on the arm 15; and the plate 9 can be retained in its free position by the lodgment of the roller in a depression between the tip of the arm 15 and a guide bar 16. The guide jacking means comprises a gripping plate 24, similar to the plate 9, from which, when in its gripping position where it is urged by a leaf spring 26, a pair of links 25 is suspended. The lower ends of the links 25 receive the fulcrum of a lever 22 which has a forked end which straddles a slide 21 and is pivoted to it. When the lever 22 is depressed the slide is forced up the standard and pulls the guide with it through suspension pins 7, the plate 9 slipping up the standard under an upward force. When the lever 22 is raised the plate 9 takes the load and the plate 24 slides up the standard to its new position, and so on. To lower the guide the gripping plate 9 is placed in the free position and the gripping plate 24 is pulled to its free position by a release cord, and the guide is then lowered by means of a cable passing over a pulley. The ends of the suspension pins 7 are spherically seated in the cross plates 6 and 29, the former being fixed to the guide and the latter seating in a part-spherical surface at the base of the slide 21. The jacking means 3 may thus be swung round the axis of the standard, and a degree of flexibility is imparted which is enhanced by the tube 4 being a loose fit on the standard at its lower part, the top only being a tolerance fit. In a modification, Fig. 4, the plate 9 is held in its gripping or free positions by the direction of throw of a spring toggle 32 actuated by an extension 33 of the upper toggle link.
