IPC: B61H11/02
Filed: 1923-06-26
Abstract: 209,678. Allen, B. June 26, 1923. Actuated by backward pressure of tractor or relaxation of pull or push; hand actuation; skid; scotch blooks; locking by positive detents.- Longitudinal movement of the draw-bars of a vehicle upon relaxation of the pull thereon effects the application of brakes to the four wheels of the vehicle and the positive locking of the trailing wheels. The brakes may be applied by hand. The sliding draw-bars e, e<1> are guided at their inner ends by extensions from a fixed block b which are received in socket parts g, g<1> on the draw-bars. A transmission shaft a which passes through the block b has arms d', d' connected by limbs r, r<1> to pins f, f<1> on the draw-bars. Pawls h, h<1> are pivoted on the pins f, f<1> which also engage in slots in the ends of the levers n, pivoted on the wheel axles. The levers n are connected respectively by pull-rods o to transverse bars j<1> extending between brake shoes k, guided by bolts working in slots m<1> in fixed members m. If the pull on the haulage rope of the vehicle is relaxed the draw-bars are urged inwardly by springs whereby the shoes k are applied between the wheels and the rail by the levers n and the pawls h, h<1> are moved into the path of ratchet wheels p on the wheel axles, one or other of which thus becomes locked according to the direction in which the vehicle tends to travel. The brakes may be operated manually by handles on the squared ends y of the shaft a or by pull rols t connected to an arm s on the shaft a and passing through holes in fixed brackets u. The rods t may be locked in position by pins x passed through holes therein.

Title: Improvements in hydraulic couplings and change speed gears
IPC: F16H39/24
Filed: 1924-07-17
Abstract: 221,191. Wingquist, S. G. Aug. 29, 1923, [Convention date]. Clutches and speed-varying mechanism.- Hydraulic variable-speed gears, comprising two or more pump elements or systems of pump elements and controlling valves, are provided with one or more auxiliary valves so arranged that the main valve or valves are closed above a prredetermined number of revolutions or below a predetermined pressure, and are opened below said number of revolutions if the pressure be exceeded. The auxiliary valves are also preferably arranged so that after cutting in a transmission ratio, readjustment to the preceding transmission ratio is allowed when the pressure is less than or equal to the pressure at which the cutting in commenced. The main controlling valve 15, Fig. 1, is connected to a piston 16 of equal, greater, or less diameter. In the latter case, the valve also functions as a relief valve. The valve is opened when a chamber 17 is connected to the pressure chamber of the gear, and is closed when the chamber is connected to the suction chamber. The chamber 17 is connected to a channel 43 communicating with apertures 42, Fig. 7, in a sleeve 20. The sleeve 20 is rotatably mounted and provided with a weight 43, Fig. 4, opposed by a spring, so that below a predetermined number of revolutions an aperture 25 in the sleeve communicates with a passage 27 leading to the pressure chamber of the gear. When the parts are in the position shown in Fig. 7, the apertures 42 and therefore the chamber 17 are connected to the suction chamber of the gear through a passage 45. The apertures 42 are connected to the pressure chamber when the pressure increases to force back a piston 32 against the action of a spring 31. When the predetermined number of revolutions is attained, the sleeve 20 moves to bring the aperture 25 into communication with a passage 29 leading to the suction chamber, so that the pressure no longer acts on the piston 32.
