Title: Improvements relating to the control of motor vehicles
IPC: B60T7/12
Filed: 1934-05-25
Abstract: 437,132. Preventing reverse movement of motor vehicles. STANCLIFFE, C. W., Warrani, Harlequin Lane, Crowborough, Sussex. May 25, 1934, No. 15692. [Class 103 (i)] A sprag, including a coil spring clutch for preventing reverse movement of a vehicle, when rendered inoperable remains so after subsequent reverse movement of the vehicle until a forward gear is engaged and the vehicle moves forward. The pawl 6 of the sprag prevents movement of the vehicle transmission shaft 4 in the reverse direction shown by the arrow 14 unless a stop 15 is raised and allows the pawl 6 to be swung clear of the ratchet wheel and against a stop 13 by a spring clip frictionally gripping a disc 11 on the transmission shaft 4, on reverse movement of the vehicle. The pawl 6 is not swung back to operative position again until the vehicle moves forward and the disc 11 is turned. The stop 15 is raised by a cam on the reverse gear shift rod 17 when reverse gear is engaged and is held in this position by a catch 39 on a rod 27 connected to the stop 15, the catch 39 engaging the edge of a slot 30 in a sliding member 31, when this is at the right hand limit of movement. The sprag is thus held inoperative when the gear lever is moved back to neutral and until the gear lever is moved to a forward gear when cams on the gear shift rods 17, 37 engage members 35, 36 on the member 31 which is moved to the left to release the stop 15 into operative position. The sprag may be rendered inoperative manually by a rod 21 and an inclined member 24. The knob 22 may be outside the body of the vehicle. The ratchet wheel 5 is freely mounted on the shaft 4 and is connected to one end of a coil spring clutch, which is enclosed in a cylindrical bore and fixed at the other end to the shaft 4. When the wheel 5 is locked by the pawl 6, reverse movement expands the coil spring against the bore and locks the shaft 4. A spring plunger may be used to assist the return of the pawl 6 to operative position. The coil spring clutch may be connected to the ratchet wheel 5 by a clutch which is released by a pedal to render the device inoperative without altering the positions of the normal controls. The upper surface of the shift rod 17 may be so formed that the sprag is rendered inoperative by only partial movement of the gear lever towards the reverse gear position.

Title: Improved method and plant for underground gasification of coal seams on fire
IPC: E21B43/295
Filed: 1945-06-20
Abstract: 602,480. Destructive distillation in situ. DEMART, P. June 20, 1945, Nos. 15753, 15754 (Convention date, May 5, 1944), 15755 and 15756 (Convention date, May 9, 1944). [Class 55(ii)] In a system of underground gasification a series of pulsations by rapid variations in pressure and velocity of the combustion air is imparted and steam may be injected to generate gas. Gases evolved from the burning coal layer 1 are evacuated through piping 4 arranged in a shaft 2 and gallery 3 through which the air for combustion is supplied. Helical or other ribs &c. on the piping will increase the heat exchange and tar extractor and dephlegmator vessels may be located at lower points. The pulsations are effected by interchanging e.g. every two seconds the air and gas passages over a part of the system, i.e. in gallery 3, by the provision of a byepass gallery 6 between shaft 2 and a gallery 10, and pairs of valves 13, 14, and 8, 9, in a forked part of piping 4 and gallery 10 respectively. The valves are so linked that valves 9, 13, and 8, 14 open and close together; when valves 8, 14 are open air is blown into gallery 3 by a fan 20 and gas is delivered through piping 4, but on reversing the valves, the air enters piping 4 within gallery 3 through a branch 11 and the gas discharges through the gallery and valve 13 into the piping beyond the forked portion. For steam generation a pump 23 feeds water from a tank 24 to a conduit 21 extending the whole length of piping 4 and connecting at its inner end with a coil 26 and an outlet conduit 22 which supplies turbine &c. 27 driving a gas compresser. Steam for water gas generation is supplied under control by means of pump 23 through a valve 31 which opens when the steam pressure exceeds the normal requirements of the turbine.

Filed: 1940-10-31
Abstract: 544,937. Fluid-pressure brakes. DAIMLERBENZ AKT.-GES. Oct. 31, 1940, No. 15927. Convention date, March 24, 1939. [Class 103 (i)] In a brake system for motor vehicles the brakes for the front wheels are applied directly by the pedal or other control member through a hydraulic transmission system and the brakes for the rear wheels by a fluid pressure servo-motor under the control of the same control member. As shown, a hydraulic master cylinder 2 connected to the cylinders 10, 11 of the front wheel brakes 4, 5 and a valve 3 controlling the supply of compressed air or pressure liquid to the cylinders 8, 9 of the rear wheel brakes are connected to the pedal 1. The resistance offerred by the liquid column when under pressure prevents the too sudden application of the rear wheel brakes. The cylinders 8 9 operate the rear brakes through a shaft 18 levers 16, 17 and links 19, 20 connected to cam levers but these cylinders may instead be arranged similarly to the cylinders 10, 11. When pressure liquid is used for the rear brakes this may be supplied by a pump connected to the intermediate shaft of the change speed gear so that pressure liquid is avaiable if, the vehicle is moving even if the engine stops. The pump may normally run empty and only begin to feed liquid to the control valve when the pedal is operated.

Title: Improvements in or relating to towing vehicles
Inventor: SHAW JOHN CHRISTOPHER SHULDHAM
IPC: B63B21/56
Filed: 1957-05-20
Abstract: 891,701. Towing winches. DRACONE DEVELOPMENTS Ltd. May 12, 1958 [May 20, 1957], No. 15935/57. Class 78 (5). Ship's diesel 1 drives D.C. generator 2 which supplies current to motors 3 and 5, of which motor 3 drives towing winch 4, and motor 5 drives propeller 6 to drive the ship. The torque applied by motor 3 to winch 4 enables slack in the towing rope to be taken up; whilst excessive stress in the rope causes the rope to pay out to relieve the stress and, at the same time, to drive motor 3 as a generator. The power so generated is used by motor 5 to drive the ship by giving extra propulsion to propeller 6. Alternatively steam may be used, the towing winch 4 driving or being driven by a turbine so that the ship's steam engine can use up the surplus energy generated by the winch.

Title: Improvements in connection with anchor carriages and the like used in the cultivation of land by mechanical power
IPC: A01B3/72
Filed: 1918-10-03
Abstract: 137,554. Estrade, J. Oct, 3, 1918. Drum or barrel winding-machines; varying height of application of pull of cable for stability. -Anchor carriages or haulage vehicles, for use with cable-traction systems for the cultivation of land by mechanical power, are provided with hand-operated or automatic means for varying the height of the point of application of the tractional stress of the cable in accordance with its magnitude, so that the resultant of the tractional force and the weight of the vehicle may pass as nearly as possible through the edge of the base of support without leaving the base. In the anchor carriage shown in Fig. 2, the cable B passes over a pulley 1 and round a roller S on to a windlass T, and the point of application of its tractional stress is lowered as the stress increases by lowering the pulley 1 by hand-operated mechanism consisting of a screw 4 and a nut 5 provided with projecting arms 6. In the arrangement shown in Fig. 5, the height of the pulley 1 is automatically regulated by the pull of the cable acting against the action of spring 7. The pulley 1 is mounted on the arm 14 of a two-armed lever 14, 15 supported on a shaft 12 in uprights 11 which are arranged to swing about a vertical pivot. The short lever arm is adjustably connected to the springs 7 by rods 18 &c. The cable B passes round guide pulleys 13, 19 between the pulley 1 and the windlass, so that its pull tends to lower the pulley 1. Fig. 7 shows a modification applied to an anchor carriage for holding a cable at a point where it is reversed. The cable passes round a pulley A mounted on a vertical member 34 of a jointed frame in the form of a parallelogram. This frame comprises also two uprights 24, two pairs of arms 28, 29, and two crcss-bars 30, 32. It is adapted to swing about a vertical pivot 21. The arms 28 are connected by a crossbar 36 to which are fixed levers 37 pivoted on a shaft 26 and adjustably connected to a compression spring 7 by a screwed rod 39 and nuts 44. The spring 7 bears against a plate 40 pivotally supported by ties 42, 43. The pull of the cable tends to make the parallelogram assume the form of a rectangle against the action of the spring 7.
