Title: Load stabilizer crane forks with automatic clamping device
Inventor: HARVEY WILBERT RAYMOND
IPC: B66C1/24
Filed: 1967-08-29
Abstract: 1,244,846. Slings for clamping and lifting loads. W. R. HARVEY. 29 Aug., 1968 [29 Aug., 1967], No. 39510/67. Heading B8H. A crane hook, Fig. 3, has load-supporting forks mounted on a carriage 104 which is raised by a lifting cable 106 so that the load is clamped between top members 102 and the forks. Fig. 4 shows an arrangement in which the members 102 are pulled down towards stationary forks. When the fork shown in Fig. 3 is set down unloaded, a plate 21, Fig. 5, moves downwards and turns levers 18 overcentre through links 12, 13, 20. This pivots arms 17 to the position shown in Fig. 6 and the fork may be loaded up. When the loaded fork is lifted, the plate 21 lifts spring-loaded one-way extension pieces 19 without moving levers 12, and passes between jaws 25, thus causing the forks to rise and grip the load. When the weight of the load is released, the plate 21 moves down to position C, Fig. 6, and pushes the levers 18 back to the Fig. 5 position. The fork is now unloaded and when it is next raised prongs 22 on the plate 21 engage holes 23 in arms 17, thus holding the arms together and preventing upward movement of the plate 21 and the lifting forks. Fig. 7 shows an embodiment in which the members 218 mounted on a carriage 211 are pulled down to clamp the load. Toggles 210 on a movable plate 129 automatically engage either the carriage 211 to hold the members 218 up for loading, or, engage and raise a pulley block 213 to pull the carriage 211 down to clamp the load. A carriage 128, which supports pulleys 220, is slidable along guides 219 by a hand wheel 223 and worm and nut mechanism. Figs. 11-16 (not shown), show a different arrangement of the cable clamping means and toggle plate of the embodiment described with reference to Fig. 7. The tips of the forks in all embodiments may be either provided with rollers to facilitate load engagement or with sleeves carrying rollers.

Title: Method and apparatus for blow molding articles of plastics material
IPC: B29C49/56
Filed: 1963-10-09
Abstract: 981,997. Extrusion-blow moulding apparatus. HOOVER BALL & BEARING CO. Oct. 9, 1963 [Nov. 8, 1962], No. 39847/63. Heading B5A. In a blow moulding apparatus the mould halves 46, Fig. 1, are carried, respectively, by a fixed platen 48 and a movable platen 50 actuated by a reversible hydraulic motor which drives a shaft connected to the centre of a toggle mechanism the ends of which are connected respectively to the platen 50 and to a member 60 connected by the rods 66 to the platen 48. The blow moulding apparatus is associated with an extruder 18 which feeds a tubular member 42 connected to an hydraulically operated accumulator 102. The flow of material to a three-headed die assembly being controlled by a valve 140, Fig. 2A. The moulded articles are removed by a pneumaticallyoperated mechanical stripping mechanism 152. The hydraulic circuit includes a low-volume highpressure pump and a high-volume low-pressure pump. In operation, with the valve 140 closed and parisons formed, the extruder operates to fill the accumulator 102 and the mould carrying platen 50 is moved to a closed position by the hydraulic motor operating through the toggle linkage. If the time to effect closure is exceeded because the platen 50 meets an obstruction a timer operates to shut-off the extruder 18 and to return the platen 50 to open position. On correct closure of mould halves a switch is actuated to switch the pump unit over to highpressure delivery so that the mould halves are forced together. The parisons are pre-blown during or after mould closure after which highpressure air is blown into the parisons through the die heads. After exhaustion of air from the parisons the hydraulic motor reverses to open the moulds at a progressively increasing speed thus avoiding sticking of an article to the mould. The stripping bracket is then moved downwardly to strip the articles from the die heads. The valve plunger 140 is moved to the open position and the accumulator plunger is moved downwardly to supply material to the die heads to form parisons. The amount of material so supplied depends on the duration of opening of the valve 140 and should this duration exceed a predetermined value a limit switch is operated to effect disengagement of a clutch in the extruder drive. The electric control circuit is described.

Abstract: 938,778. Fluid-pressure brakes. FIAT S.p.A. Nov. 9, 1961 [Nov. 11, 1960], No. 40212/61. Class 103 (1). [Also in Groups XXIV and XXXI] A forward-reverse planetary gear (see Group XXIV) comprises a friction disc brake 14, Fig. 4, engaged when oil under pressure is supplied through a pipe 37 to act upon a ring-shaped piston 17, thereby stationing a planet carrier 8 and establishing reverse, and also comprises a disc brake 19, engaged when oil under pressure is supplied through a pipe 50 to act upon a ring- shaped piston 20 and station the gear output shaft 7. An engine-driven pump 22 supplies oil under pressure from a gear sump to a pipe 21 and a main duct 26, Fig. 3, in a multiple valve assembly, a pressure relief valve 24 therein opening to a gear lubricating pipe 25. To engage the disc brake 14, a control shaft 43 is turned so that a cam 42 opens a valve 35, thus connecting main pressure 26 to the pipe 37 and the servo piston 17. Oil pressure in the pipe 37 also acts upon a ball valve 66 which moves to prevent transmission of oil to a pipe 28, and simultaneously opens a pipe 65 so that oil pressure is supplied therethrough to a cylinder space 47, where it acts rightwards upon a servo piston 46, biasing a detent roller 45 into engagement with a cam 44 carried by the control shaft 43, whereby the latter is maintained in its brakeengaged position. A similar valve 31 is opened to supply oil under pressure to the pipe 28 and thus engage a forward drive clutch (see Group XXIV). Maintenance of pressure in the pipe 65 and the servo space 47 closes a valve 48. When both the brake valve 35 and the clutch valve 31 are in their closed positions, pressure in the pipe 65 and the space 47 falls, and the valve 48 is opened, so that main pressure 26 is supplied to a pipe 50<SP>1</SP>. If a main change-speed gear following the planetary reverse gear is in its neutral condition, a valve 52 is opened, so that the oil pressure in the pipe 50<SP>1</SP> passes to the pipe 50 and engages the shaft brake 19.

Title: Yarn tension control device
Inventor: NORRIS ALAN HEDLEY
IPC: B65H59/22
Filed: 1963-10-15
Abstract: Apparatus for controlling yarn-tension comprises a series of pairs of discs; of each pair, one disc is of non-magnetizable material and is attached to a pair of spaced magnetizable bars, while the other disc is of magnetizable material and is so arranged that its position relative to the other disc, and therefore the tension of the yarn, can be controlled by magnetic flux.  By this arrangement, an adjustable uniform tension can be maintained in each of a number of yarns passing from a reel to a winding or knitting machine or to a warp beam.  At intervals along a pair of spaced parallel bars are fixed a number of non-magnetic spacers, Each spacer carries a non-magnetizable fixed disc with a post slidably carrying a magnetizable disc.  The latter discs are drawn towards the fixed discs by creating magnetic flux in the bars.  This is done (a) by permanent magnets, the flux being varied according to the tension desired by shorting-out some of the flux by magnetizable pieces laid across the bars, or (b) by energizing a coil with A.C. or D.C. of the required voltage, means being provided when D.C. is used to remove residual magnetism e.g. by applying D.C. before current changes are made.  A basic tension can be established by putting weights on the upper disc.  One yarn may pass through more than one pair of discs as that the required tension may be applied in stages.
