Abstract: 391,777. Loadhandling machines. ELECTRICARS, Ltd., TREECE, J. W., and JONES, C. E., 45, Lawley Street, Bir. mingham. Oct. 26, 1931, No. 29655. [Class 78 (iii).] - A load-handling machine comprises a truck frame, a supporting structure pivoted on said frame about a vertical axis, said structure having an arm extending longitudinally of the truck, an extensible jib pivoted to the projecting end of said arm, and hydraulic means for raising and lowering the jib and for adjusting the length thereof. As shown in Fig. 1, the jib, comprising telescopic channel members 19, 21, is pivoted on an arm 17 projecting from a structure 16 on a turntable 8 carried by a self-propelling truck 2, and is extended by a piston 31 operating in a cylinder 33 and raised by a piston 26 operating in a cylinder 27. Fluid is supplied to these cylinders by a pump driven by an electric motor, and the pressure is controlled by valves 40, 39, Fig. 6, which are arranged as shown diagrammatically in Fig. 10 and are selectively actuated by a lever 55, Fig. 8. This lever is mounted on a ball joint 56 and is connected by ball joints 61, 62, Figs. 5 and 8, and links 65, 68, to levers 66, 63, on the valve spindles 67, 64, respectively. The links 65, 68 are ball-jointed at both ends so that when the lever 55 is swung vertically, the valve 39 is actuated through the link 65 but the valve 40 remains stationary, the link 68 swinging about its ball joints. The valve 40 is actuated when the lever 55 is swung horizontally. When either of the levers 63, 66 is operated a cam 69 thereon engages a roller 70 and actuates a rod 74 to close a switch controlling the pump motor, the switch being reopened when the lever 55 is returned to its neutral position. The rod 74 may operate a clutch when motive power other than an electric motor is employed. The relative movement of the jib members 19, 21 is limited by stops 91, Fig. 1, on the member 21 which, in the limiting positions, engage a cam 92 on a spindle carrying a crank-arm 93 connected to the valve lever 63 by a rod 94, whilst the pivoting movement of of the jib is limited by stops 95, 96, which engage an arm 97 of a lever 98 connected to the valve lever 66. Either or both of the axles of the truck may be unsprung so that the wheels and transmission gear serve as a balance weight to prevent tilting of the truck under load. A block 103, moving in guides 104 and connected to the jib by a chain 105, is provided with a roller 106 which engages a U-shaped guide 107 to limit movement of the frame 16 about its vertical pivot.

Filed: 1972-07-06
Abstract: 1376445 Weighing apparatus G H ROGER 6 July 1972 [25 June 1971] 29805/71 Heading G1W A spring-balance has the spring 30 mounted so that over a first range of movement from zero a greater length of the spring is employed than over subsequent range(s) of movement, so that the movement of a pointer 20 per unit increase in load is greater over the first range than over the subsequent range(s). In Fig. 1, a vertically movable member 14, guided by parallelogram links 27, 29 pivoted to a frame 24, supports a weighing pan 18 and is connected by a horizontal arm 35 to a rack 37 meshing a pinion 39 on the pointer shaft. The arm 35 is also connected at 32 to the lower end of a helical tension spring 30. The spring upper end is anchored to a crossmember 42 secured to a threaded tie-rod 36 by nuts 54. The tie-rod is supported on the frame 24 by a nut 38 for zero adjustment. A similar crossmember 56 is secured part way down the spring, to be freely slidable on the tie-rod 36. For the first range, up to 11b, the whole spring 30 is effective. At a load of 11b the cross-member 56 engages a stop 40 on the lower end of tie-rod 36, so that for higher loads, only the lower section of the spring, between 56 and 32, is effective. The members 42, 56 Fig. 6 comprise a tube 44, e.g. of nylon, with a 270 degree helical rib 48 to engage between turns of the spring. Recesses 50 facilitate manual adjustment. Fig. 7 and 8 (not shown) concern balances with load-suspension hooks 18 using the above tworange principal, that of Fig. 8 having two springs in parallel. Fig. 9 shows a balance using a compression spring 30. The stop 40 is adjustably secured to the tie-rod 36 on which the hook 18 is formed. At the end of the first range, the stop 40 abuts the cross-member 56, so that for higher loads only the lower portion of the spring, between 56 and 34, is effective.

Abstract: 231,219. Sperry, E. A. Nov. 27, 1923. Cylinders receiving liquid fuel.- In an engine in which at the end of the compression stroke air in the cylinder is forced by the piston into a toricshape combustion chamber 10 with a vortex-like motion, the throat 12 and projection 13 on the piston are so shaped that the annular passage formed between them rapidly becomes less in area as the piston ascends, which ensures that the air enters the combustion chamber at a gradually increasing velocity with a high final value. Spiral flutes 18 formed on the projection 13 may be cooled by mercury or a mixture of nitrates 20 contained in a sealed jacket. The combustion chamber is cooled by mercury 22 which condenses on projections 25 cooled by a water chamber 23. Fuel is injected radially through a nozzle 11. In a multicylinder twostroke cycle-engine the air for combustion is supplied under pressure from a source common to all the cylinders, and enters each combustion space through a valve 26. Terminal exhaust ports are opened after and closed before the valve 26.
