Title: Improvements in and relating to anti-dazzle screens more especially intended for useon automobile vehicles
IPC: B60J3/02
Filed: 1927-09-07
Abstract: 285,750. Urithzen, O. J. Sept. 7, 1927. Anti-dazzle screens.-In an anti-dazzle screen for the use of the vehicle drivers of the kind which is capable of adjustment by rotating on a pivot secured to the wind-screen by one or more suction cups and is normally retained in an outof-use or inoperative position, meansare provided for automatically transferring the screen to its operative position when desired. Preferably, the screen is also adapted to be automatically retained in any adjusted position required, and it may be automatically returned to its inoperative position. In the construction shown in Fig. 3, the beaded rim b of the anti-dazzle screen a is clamped between a cylindrical bush e and a cap p threaded thereon, these parts being rotatable on a tubular pivot g attached to the suction cup c and having a narrow stem portion g<1> in which is slidable a rod n provided with a finger-cap d. A spiral spring i located within the bush e has one end connected to a slot in the stem g<1> and the other end to the bush, and normally tends to rotate the bush and anti-dazzle screen to an upward or operative position. The bush is retained in any adjusted position by the co-operation of a disc on the bush having a circular series of stamped-up rack teeth l<1> with a fixed stop m<1> on a disc m in the tubular pivot g. Thus, the cap p and bush e can be rotated to move the screen a to any desired position, where it is automatically held, and, subsequently, by pressing inwardly the rod n, the stop m<1> is freed from the rack teeth l<1> and the spring i is allowed to restore the screen to its operative position. Braking means may be incorporated to slow the return movement. In a modification, Fig. 15, in which a shaft 43 carrying the anti-dazzle screen, is supported in a tube 41 fitted with two suction cups 42, a solenoid 48 is energized when desired to attract a core 49, which actuates the shaft 43 through a rack 46 and pinion 44 and is returned to normal position, when the electric circuit is broken, by a spring 53. The solenoid and core may'be replaced by a spring-controlled piston actuated by suction from the induction pipe of the motor. In a further modification, two solenoids are employed, which are selectively energized to place the anti-dazzle screen in its operative or inoperative positions, and a locking- pawl automatically retains the screen in either of these positions.

Title: Emergency brake system for automatic compressed air brakes for railway carriages
IPC: B60T17/22
Filed: 1976-06-08
Abstract: 1527815 Emergency braking in rail vehicles WERKZEUGMASCHINENFABRIK OERLIKEN-BUHRLE AG 8 June 1976 [4 July 1975 15 Aug 1975] 23559/76 Heading F2F An emergency brake system for automatic compressed air brakes in railway carriages comprises an emergency brake handle 29 in the carriage, operation of which causes brake pipe 10 to be vented by an emergency valve 11 and also causes an indicating lamp 68 in the drivers cab to light up whereupon an auxiliary valve 21 is manually operable by remote control to suppress venting of the emergency valve 11 if emergency braking is not desirable, e.g. if the train is in a tunnel. In a first embodiment shown in Fig. 1 the operation of handle 29 vents a connecting pipe 28, which communicates with a chamber 17 of emergency valve 11 via auxiliary valve 21, to cause the pressure in chamber 16 of the emergency valve to raise piston 15 to vent the brake pipe 10 via chamber 12 of the emergency valve. An electropneumatic switch 38 operates both indicators 68 in the drivers cab and 39 in each carriage when there is a certain pressure drop in connecting pipe 28, indicating that the handle 29 has been pulled, which causes movement of piston 32 to close an electrical switch. The driver can then operate auxiliary valve 21 by closing switch 43 to isolate chamber 17 of the emergency valve 11 from vent valve 27. In a second embodiment (Fig. 2, not shown) switch 38 is omitted and the lamps are switched on by movement of the piston 13 of the emergency valve 11 itself, there being a time delay interposed between the switch 43 and auxiliary valve 21 to close the latter for a given time period. A third embodiment (Fig. 3, not shown) includes the same arrangement as that of the second embodiment except that a holding relay is provided whereby the lamps 39 and 68 may remain alight even after emergency valve 11 has closed as long as a manually operated switch is closed. A fourth embodiment (Fig. 4, not shown) has the same arrangement as the first except that only the lamp 39 is lighted in the carriage where the handle 29 was pulled in addition of course to the lighting of lamp 68 and also the auxiliary valve 21 is modified such that the valve member thereof is integral with a piston slidable in the valve chamber 24. In a fifth and final embodiment having an arrangement similar to the first, the operation of pneumatic switch 38 completes two circuits simultaneously, the switch being a snap action two position switch, and there being additionally incorporated a second pneumatic switch responsive to the pressure in chamber 12 of emergency valve 11, i.e. brake pipe pressure. The electrical circuit is arranged such that once the driver has operated auxiliary valve 21, it will not re-open until both switch 38 and the second switch have reopened, i.e. when emergency brake handle 29 has been reset and brake pipe pressure has been restored.
