Title: Vehicle brakes
IPC: B60T11/04
Filed: 1928-09-20
Abstract: 322,267. Riley (Coventry), Ltd., and Riley, S. Sept. 20, 1928. Force-transmitting mechanism; compensating for wear.-In a vehicle brake system, a cable at each side of the vehicle connects applying mechanism for a front brake with applying mechanism for a rear brake, and means are provided for adjusting the effective length of the cables by the interposition of an adjusting screw, of which the nut is accessible from the driver's seat. Two levers 5, Fig. 2, connected to move together are pivotally mounted on a shaft 4, one on either side of a housing 2' situated behind the gear box. Pulleys 6 are mounted at the ends of the lever arms and guides 7 are formed integrally with the lower lever arms. A single length of cable 8 extends rearwardly from the expander lever of one front brake and passes round a pulley 11, the guide 7, and the lower and upper pulleys 6 to a position adjacent to the rear axle, where it is led around a freely-mounted guide pulley and thence forwardly again, round the second pair of pulleys 6 to the other front brake. The freely mounted guide pulley mentioned above is attached to a device adapted to apply both rear-wheel brakes as described in Specification 321,508. A sleeve freely mounted on the shaft 4 is formed with two arms 15, 16 connected to the brake pedal and to a pair of upward-extending parallel links 17, respectively, and the links 17 are pivotally attached at 18 to a. pair of levers 19 onthe chassis. The pivot pins 18, Fig. 3, constitute trunnions for a block 22 through which extends a threaded spindle 23. The spindle 23 is adapted to be operated by a handwheel or nut 24 passing through a hole 31 in the floor board 32, and its lower end engages a threaded block 25 rotatably mounted in a V-shaped member 26 of which the two ends 27 are bolted to one of the pulleycarrying levers 5. The arrangement described above provides compensation between the front and rear brakes and between the individual front brakes. Means may be provided for dispensing with this compensation; these may consist in the use of a clamp 29 which can be tightened down by a screw 30 on to the cable 8 where it passes over the two lower pulleys 6 and grips the cable into the groove of the pulley. In an alternative arrangement compensation between front and rear brakes but not between the individual front brakes may be obtained by clamping the cable 8 to the freely mounted pulley connected to the rear brake applying mechanism; this may also be effected by the use of two separate cables between front and rear brakes, one on each side.

Title: An improved electric remote control installation employing direct current impulses
IPC: H02J13/00
Filed: 1938-09-16
Abstract: 508,160. Electric control systems. LANDIS & GYR AKT.-GES. Sept. 16, 1938, No. 27045. Convention date, Oct. 8, 1937. [Class 40 (i)] In a control system wherein selective operations at remote stations are effected by D.C. impulses transmitted over the neutral-earth circuit of an A.C. power network, synchronously operated selector switches 19 at the remote stations are started and effect the necessary selective operations under the control of D.C. relays. As shown, the D.C. relays 8 are of the three-position type, and are connected between the neutral line 1 and earth of a power network 1 .. 4, a choke 11 or a decoupling circuit 29 and a condenser 12 being provided to exclude the network current from the relay. In response to a positive impulse transmitted by the contact 7 of the transmitter A, shown diagrammatically, relay 8 at each station is operated and a synchronous motor 17 which drives the contact arm 18 of the selector 19 is started up over contacts 13, 14 of therelay. A contact 26 is operated to maintain closed the motor circuit during a complete rotation of the selector. During the rotation, a negative impulse is transmitted to close a circuit over the contacts 13, 15 and the arm 18 and any one of the selector contacts depending on the time incidence of the impulse When the arm 18 regains its normal position, contact 26 is opened to stop the motor. In a modification, two-position relays 8 are employed, each relay being connected to the network through a change-over-switch which is operated just after the synchronous motor is started to effect reversal of the relay connections preparatory to operation of the relay' by the negative selecting impulse.. In a further modification, the change-over-switch is dispensed with and selecting impulses of the same polarity as the starting impulse are used. A selective operation may also be effected by the transmission of a code combination of impulses during the rotation of the selector. Specification 496.422 is referred to.

Title: Improvements in gas-filled electric switches
IPC: H01H33/56
Filed: 1962-07-18
Abstract: 967,521. Heavy current switches. WESTINGHOUSE ELECTRIC CORPORATION. July 18, 1962 [Sept. 19, 1961], No. 27596/62. Heading H2B. A switch in a sealed enclosure containing arc extinguishing gas, such as the switch of Specifications 967,522 and 967,523, has a device responsive solely to a drop in the density of the gas to prevent the opening of the switch if gas is lost from the enclosure. The device is a sealed bellows 102 mounted on the frame 24 of the operating mechanism within the enclosure. The free end of the bellows carries a lock-pin 103 so that should gas be lost from the enclosure, the bellows expands and moves the pin 103 into the path of movement of the pivoted lever 19 of the lever system described in Specification 967,522, so preventing the opening movement of that system. A recess may be provided in the side of the lever 19 so that should the contacts be open when a loss of gas occurs, the pin 103 engages in the recess and prevents the reclosing of the contacts. The bellows may be filled with the same gas as that in the enclosure so as to be insensitive to pressure changes due to changes in temperature. Should the bellows leak, the pin 103 is moved to prevent operation of the switch. The pin 103 may have a transverse pin 111 which, when the bellows expands, prevents the tripping movement of a trip bar 112 and so prevents the tripping of the switch by the mechanism described in Specification 967,523.
