Filed: 1937-06-04
Abstract: 502,157. Actuating controliers. SKODA WORKS, PLZEN. June 4, 1937, No. 15514. Void. Convention date, June 4, 1936. [Class 38 (iii)] A controller 45 regulating series resistance in a motor circuit, and a shunt field regulator 53 are operated by a common pedal 1, the controller 45 being first operated while the regulator 53 is stationary, and the regulator 53 being subsequently operated while thecontroller 45 remains stationary. Upon depression of a pedal 1 a cam 9 mounted on a shaft 8 is rotated to permit a spring 16 to operate rollers 14, 15, into engagement with a disc 18 freely mounted on the shaft 8, and to operate pawls 24, 25, into engagement with a disc 23 also freely mounted on the shaft 8. A lever 17 mounted on the shaft 8 engages a stop member 19 carried by the disc 18 and as the shaft 8 is rotated the disc 18 is rotated to stress a spring 21 coupling the disc 18 with the disc 23. The latter is prevented from rotating by the pawl 24, but when the disc 18 has operated the roller 14 by means of one of its projections, the pawl 24 is released and the spring 21 operates the disc 23 through an angle until stopped by the pawl 25. This pawl is subsequently released by a projection on the disc 18 lifting the roller 15 and the disc 23 is operated a further step. This action is repeated and the stepped rotation of the disc 23 is transmitted to a freely mounted gear wheel 27 which operates the controller 45. When the controller 45 has been operated to its final position a member 26 connected to the disc 23 lifts a roller 28 whereby a roller 30 releases a pawl 33 which is operated by a spring 34 into engagement with a disc 32 fixed to the shaft 8. The pedal is then released to permit the shaft 8 to return until the pawl 33 engages a tooth on the disc 32. When the pedal is again depressed the coupling between the disc 32 and the pawl 33 causes rotation of a wheel 37 gearing with a wheel 49 coupled with the moving brush 52 of a commutator tyre shunt regulator 53. Thus the shunt regulator may be adjusted. When the pedal is fully released the cam 9 operates the rollers 10, 11, to release the disc 23 and the controller 45 is returned by a spring 47. The shunt regulator is returned by a spring 39.

Filed: 1927-06-10
Abstract: 298,515. Cadbury, G. N. June 10, 1927. Fluid-pressure; skid.-In fluid-operated wheel and track brakes for tramway and other vehicles, the wheel brake is released when the track brake is applied by the provision of a release valve for the wheel brake adapted to be operated by the fluid used for actuating the track brake. Compressed air is supplied to wheel and track brake cylinders p, r respectively by valves u, v from reservoirs b. Before compressed air is supplied to the track brake pipe 2 it must raise a pair of spring pressed valve pistons y, z whereby the wheel brake pipe 6 is cut off from the valve u and is connected to an exhaust port 7, thus releasing the wheel brakes if these have been already applied. A piston valve 5 sliding in a cylinder 4 serves to isolate the track brake cylinders r from the control valves at one end of the vehicle when the brakes are controlled from the other end. According to the Provisional Specification, the two sets of brakes are controlled by a common lever and a release valve for the wheel brakes may be operated by a cam when the lever approaches or reaches the position for applying the track brakes. Specifications 9274/13 and 294,593 are referred to.
