Title: Improved control system for the drive of an endless track vehicle
IPC: B62D11/10
Filed: 1959-05-15
Abstract: 863,238. Steering endless track vehicles. GENERAL MOTORS CORPORATION. May 15, 1959 [July 1, 1958], No. 16715/59. Class 79(2). An endless track vehicle has two toothed gear mechanisms 131, 132, Fig. 3, each for transmitting drive from the engine to an associated drive shaft 133, 134, each of which mechanisms is controllable by a single member 45, Fig. 1, to transmit direct or reverse drive to, or disconnect the drive from, the associated drive shaft. The drive comprises a torque converter 10, a change-speed gear 11 and a unit 12 having two pairs of epicyclic gear assemblies 131, 132 controlled by hydraulically-actuated brakes 102, 107 whereby the sprocket drive shafts 133, 134 may be driven in the same or in opposite directions. When the hand lever 45 is moved forwardly a linkage 41, 33, 26 displaces a valve 20 to the left so that fluid from a supply conduit 58 flows through pipes 65 valves 22, 23 and pipes 101, 103 to engage the forward drive for both tracks. During initial movement of the valve the supply passes freely into pipes 74 supplying a cooling arrangement for the brakes of the epicyclic gears. Further travel of the valve causes a land c to throttle the flow into the pipes 74 and thereby increase the pressure in the pipes 65. "Feel" is,provided at the hand lever 45 by the difference in the areas of land a and c which are both subject to fluid pressure. The valve 20 may be moved to the right to engage the reverse drive for both sprockets and also has a central or neutral position, the valve being located in each of its settings by spring-loaded balls 56 co-operating with annular, grooves 54. The valves 22, 23 may be operated selectively by the hand lever 45, a ball joint 32 being provided in the link 26 for this purpose. When one of these valves is displaced until a land b closes the pipe 65 the corresponding clutch is disengaged to cause the vehicle to turn. If a sharp turn is required the valve is displaced until the groove between lands d and c is in register with one end of a conduit 90 which receives fluid from an annular groove in communication with the pipe 65. A bore 88 in the 'valve and a conduit 108 allow the fluid to close the appropriate reverse clutch and reduce the turning radius of the vehicle. The' rate of turn may also be adjusted by manual or automatic actuation of brakes 147, 146.

Abstract: 626,413. Harvesting root-crops. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN, Ltd. (International Harvester Co.). June 25, 1947, No. 16767. [Class 6(iii)] A beet-topping unit carried beneath a tractor comprises a power-driven discknife 32, mounted floatingly on parallel links, and preceded by an adjustable gauge device 15 attached to the links so as to control the rise and fall of the disc, the unit being liftable by the action of a hydraulic cylinder 81. The disc is carried on a housing 29 projecting from a gear-box 30 and is driven from the power take-off 45 through chains 43, 39, 35. The gear-box is pivoted to a bracket which includes a U- shaped arm 22 pivoted in a sleeve secured to a plate on the tractor. The arm 22 is connected by a telescopic link 75 to a digging unit 16 including a share 83. Both the digging unit and the topping unit are lifted by a hydraulic cylinder 81 secured to the rear axle housing 14 but, because of the telescopic link 75, the topping unit is permitted a limited floating movement. The gauge device 15 comprises a fork-like member 54 connected by a pivoted link 49 to the gear-box 30, and connected by an adjustable link 57 to an arm 58. A link 47, parallel to the arm 22, connects the link 49 with a bracket fixed to the tractor. The arm 58 forms one arm of a bell-crank, of which the other arm 59 is mounted on a rod 69 rotatable by a handle 72 to adjust the member 54 relatively to the disc 32.

Filed: 1958-05-30
Abstract: 854,004. Hydrants. MERRYWEATHER & SONS Ltd. April 24, 1959 [May 30, 1958], No. 17371/58. Class 69 (1). An hydrant installation is composed of a number of hydrant valves at different levels connected to a common rising main and having different valve openings so graduated as to prevent the development of excessive pressure in the hose at lower floor levels with a pressure in the rising main sufficient for fighting fires at the highest floor level. The inlet to each hydrant valve (Fig. 1) is controlled by a valvehead 3 having a tapered protuberance 8 which gradually restricts the inlet of water as the valve is closed by rotating a spindle. By suitable choice of the length of the sleeve 6 at each of the different floor levels, the maximum effective valve openings at different levels may be graduated. In a modification the stop 10 is replaced by an orifice plate 13 (Fig. 2), the size of the orifice being varied to suit the valves at different floor levels. In a further modification, a disc 14 (Fig. 3) is fixed to the protuberance 8. Discs of different sizes are used at different floor levels.

[Classes 83 (ii) and 83 (iv)] Welding.-In the manufacture of metal window frames having intersection joints of the astragal bars, the distorted raised table a<2> Fig. 1, of one bar is pressed down into contact with the upper surface of the table a<3> of the transverse bar and is simultaneously welded thereto. Apparatus for carrying out the method comprises jaws B, B<1>, Fig. 6, providing slots b, b<1> for receiving the webs a of the astragal bars, and supports C for the projecting ends of the bars. The jaw B is moved relatively to the jaw B<1> to grip the bars by means of a pneumatic cylinder F or by electric, hydraulic or mechanical means such as a screw or lever, and whilst the bars are clamped an upper electrode is pressed down on the table a<2> by a double acting pneumatic cylinder controlled by an electrically-operated valve, or by hydraulic or mechanical means. The jaws rest on a block mounted on a strip of copper insulated from the frame of the machine and the upper electrode is carried by a laminated copper connection, the welding current being applied simultaneously with the clamping pressure. The jaws are cooled by water circulating through pipes H and the upper electrode is also water cooled. Two movable jaws may be provided operating at right angles to clamp the webs of both bars simultaneously.
