Title: Hydraulic transmission systems
Inventor: PRITCHARD CHARLES MONTAGUE COR
IPC: B66D1/08
Filed: 1963-05-31
Abstract: 1,079,857. Hydrostatic transmission control. JOSEPH LUCAS (INDUSTRIES) Ltd. June 1, 1964], May 31, 1963], No. 21838/63. Headings F2C and F2D. The angularity of the swash-plate 14 of a variable-capacity pump 18 feeding a fixedcapacity swash-plate motor driving a winch used, e.g., for docking a ship, is automatically adjusted by pressure of the working liquid so that both the ratio and direction of liquid flow through the motor can be varied to maintain constant working pressure. Pump swash-plate angle is controlled by a transverse piston 17 loaded on its upper face by pump delivery pressure 19, and on its larger lower face by a spring 18 and pump delivery pressure 19 reaching it through a restrictor 26, communicating also with a spill port 25, controlled through an adjustably spring-loaded lever 24, actuated by a piston 23 loaded by pump delivery pressure 19, any change in which thus varies the spill port opening and hence the rate of flow through the restrictor 26. This disturbs the pressure-balance on the ends of the piston 17 which then moves the swash-plate 14 to restore constant delivery pressure. Should excessive load on the winch cable reverse the motor, the latter will then act as a pump, and the working pressure, acting through the piston 17, will move the pump swash-plate 14 over centre to rererse the flow direction, whereupon the pump,. acting as a brake, restores working pressure to its constant value, thus maintaining constant cable tension.

Abstract: <PICT:0649031/III/1> <PICT:0649031/III/2> In a machine for coating articles, the articles are carried by spindles on a conveyer system, means are provided for rotating each spindle at a coating station where coating means are fitted and are supported at an angle having a component normal to the curved surface generated by the rotating article and means are provided to move the coating means along a linear path having a component normal to the axis of the spindle at a speed which varies inversely to the change in surface area of the article. Referring to the drawings, hoods 1 to be painted are mounted on spindles 2 supported by hangers 6 pulled by conveyer chain 7 so driven that a dwell occurs just before booths 20 and 120 and at the dwell pulleys 9 engage belt 10 so rotating spindles 2.  The gun carriage mechanism, Figs. 3 and 4, comprises chassis 122 carrying guides 126 engaged by flanged plates 128 of carriage 127 which is <PICT:0649031/III/3> <PICT:0649031/III/4> <PICT:0649031/III/5> connected to chain 131 by rod 133 pivotally connected to carriage 128 and also to block 134 carried by chain 131 so that as the chain 131 is driven by shaft 129 through sprockets 130 and 132 the carriage reciprocates up and down in the guides 126.  Gun arm 135 is journalled in bearing 136 on the outside of 127 and extends through a slot 121 in the booth and carries a spray gun 137.  The other end of arm 135 has a cam follower 138 running in tracks 139 of such curvature that the gun is constantly spaced from but normal to the surface being sprayed.  In the carriage drive control system, Figs. 6 and 7, motor 50 drives expansible pulley 52 adjusted by screw 51 until the speed of shaft 29 is in phase with the conveyer system.  If yoke 58 is pivoted upwards the tension of the belt from pulley 55 pushes member 59 towards driven member 61 decreasing the driving diameter between members 60 and 59 and so increasing the speed of rotation of the double expansible pulley 56, and also decreasing the driving diameter between members 59 and 61, thus increasing the speed of driven pulley 62 and so the speed of shaft 29 and so that of carriage 27. Conversely a downward movement of the yoke 58 decelerates the carriage.  Cam follower 73 on the yoke 58 is held against cam 72 by spring 74, so that any desired acceleration or deceleration of the carriage is obtained from the contour of cam 72. On and off cam 75 is so contoured that follower 76 opens and shuts valve 77 operating the spray gun at the required points.

Filed: 1924-09-24
Abstract: 231,086. Adrian, J. Sept. 24, 1924. Sewing-machines; starting and stopping gear. - A device for stopping a shoe-sewing or like machine at a predetermined position, which comes into action at a predetermined speed, comprises a lever connected to one end of a brake-strap and lying in the path of a rotating weight pivoted so that it moves inwards to engage the lever when its speed of rotation diminishes sufficiently. A shaft 1 which is to be stopped is driven from a shaft 2 actuated through clutch gear operated by a clutch and brake lever m which is moved manually to start the machine. A brakeband k surrounding a drum a on the shaft 1 is connected at one end to a stud on a lever v actuated by the treadle. The other end of the band is connected to one arm of a lever i pivoted at y and having a second arm on which is pivoted a hook-member i<11>. The end x of the lever v is wedge-shaped and when raised moves the part i<11> laterally into the path of a stud g on one of a pair of interconnected weights c, d pivoted to the drum. When rotating at speed these weights move outwardly into contact with the periphery of the drum, but when the speed is reduced owing to the declutching and braking the weights are moved inward by a spring f till the stud g engages a notch in the part i<11> and causes the sudden application of the brake and stoppage of the shaft. In a modification the separate journals for the levers i, v are dispensed with. The shaft 1 to be stopped is journaled in a hub o, Fig. 9, on which swings a lever i carrying one end of the band k, the other end being attached to a slide p attached to the treadle. The slide carries a gudgeon u projecting through a slot in the lever i into the range of the stud g carried by one of the weights. When the stud contacts with the gudgeon both the lever i and the slide p are moved laterally but the end of the band attached to the lever has a greater movement than the end attached to the slide and the band is therefore tightened upon the drum.
