Title: Safety locks for power driven lifts & hoists
IPC: B66B13/08
Filed: 1922-10-05
Abstract: 210,483. Gravell, W. G. Oct. 5, 1922. Lift cages and doors, locking and unlocking and operating.-Relates to lift systems in which the locking mechanism of the collapsable landing gates and cage gate is connected with the controlling mechanism of the cage in such a way that these gates cannot be unlocked unless the cage is at the floor and the cage cannot be actuated when the gates are open. The cage may be controlled by a handing rope or switch. A casing L, Fig. 1. on the cage contains a grip D, E for the control rope M and a bolt G<1> for locking the cage gate. Within the cage a handle A is mounted on the end of a shaft A<1> cast integrally with the cam member D of the grip. A handle B is mounted on a sleeve surrounding' the shaft A<1> which is formed integral with an arm F. A bolt N passed through a slot in the arm F is attached to a slidable member G which is connected to the bolt G'. The member G is guided by rods G<2>, P, and is acted on by the spring P<1>. A recess G<3> in the member G receives the lower end of the member D when in inoperative position and is so shaped that movement of the handle B is prevented until the handle A has been slightly moved. When the member G is moved an inclined face on it forces the member D further into engagement with the member E. The aperture in the casing through which the bolt passes is covered when the gate is unlocked by a plate H which is mounted on guides H<1>, H<3> and acted on by a spring H<2>. An inclined surface on the bolt raises the plate when the bolt is moved to lock the gate. Outside the cage a handle C is mounted on a spindle R in the casing and is formed with an extension which acts on the members D, G so that the control rope can be locked and the gate unlocked from a landing. A key Q, Fig. 2, bolted to the member G is shaped to pass between the sides of the lock of each landing gate and to engage the slide c, Fig. 3, which is connected to the bolt f. The slide c moves on guides e, i and is acted on by a spring e<1>. When the cage is controlled by a switch, the contact maker is mounted on the slide. Tampering with the bolt is prevented by a pair of pivoted arms k connected by a bridge piece d which is acted on by springs d<1>. The slide c engages in recesses in the arms k and is only released when the bridge d is forced back by the key Q. The aperture for the bolt in the casing is covered when the gate is unlocked by a plate g carried by a rod having a rack m, Fig. 6, at its upper end. The rack m meshes with a pinion n which when the gate is nearly closed is engaged by a rack o attached to the gate and rotated to raise the plate. The pinion is locked by a pawl p which is disengaged by the rack.

Title: Improvements in or relating to direction indicators
IPC: B60Q1/38
Filed: 1954-09-24
Abstract: 782,273. Electromagnetic interrupters. SIMMS MOTOR UNITS, Ltd., and ROBINSON, E. L. Sept. 22, 1955 [Sept. 24, 1954], No. 27723/54. Class 38 (5). [Also in Group XXXVIII] A contact device 6 for flashing direction indicator lights on a vehicle (see Group XXXVIII) comprises two operating coils 9 and 10 arranged in parallel but with a condenser 11 in series with the coil 10, as shown. The coils 9 and 10 are wound such that their magnetic effects oppose when current passes in the same sense in each. An armature 14. carries moving contact 15 which co-operates with fixed contact sl6 and 17. The armature 14 is biased to hold moving contact 15 against fixed contact 16. When the direction indicator switch 5 is moved, for example, to the left as shown, a circuit is established from battery 26 through lamps 3 and 1 to the operating coils 9 and 10, and thence via contacts 16 and 15 to earth. Lamps 3 and 1 do not light owing to the resistance of coils 9 and 10. The current in coil 10 as condenser 11 charges causes opposition of coils 9 and 10, until the condenser is charged, whereupon coil 9 attracts the armature 14 which moves over to make contacts 15 and 17 and flash lamps 3 and 1. Coils 9 and 10 are simultaneously disconnected from the external circuit and condenser 11 discharges via the closed loop formed by the coils. Thus current flows in opposite senses in the coils 9 and 10 and the armature remains attracted until condenser 11 is discharged. The armature then returns to close contacts 15 and 16 and the cycle repeats.

Filed: 1955-09-30
Abstract: 798,967. Cooling systems for internal combustion engines. RUSTON & HORNSBY, Ltd. Oct. 1, 1956 [Sept. 30, 1955], No. 27806/55. Class 64(3) In a cooling system for an I.C. engine in which cooling liquid delivered by a pump 11 passes through the cooling jacket of the engine 13 to a thermostatic valve and thence either to a sump or back to the pump, an alternative discharge channel is provided for flow of liquid from the pump and includes a pressure operated relief valve so arranged and set as to permit discharge when the thermostatic valve is closed. In the marine installation shown, the thermostatic and relief valves (not shown) are incorporated in a single control unit 16. Pump 11 draws up sea water a portion of which passes through the engine jacket from an inlet port 12 to an outlet port 14, thence to an inlet port 15 of the control valve unit 16 from which it is directed by the action of the thermally controlled valve initially, when the engine is cold, to the port 18 leading to the suction side of the pump 11 and thereafter, when the engine has warmed up, to port 17 leading overboard. The remaining portion of the water leaving the pump 11 passes to an inlet port 19 of the control valve unit 16 and is there operative upon a spring loaded relief valve such that if sufficient pressure exists in the system indicating that sufficient coolant is passing through the engine cooling jacket, then the relief valve is forced open and coolant flowing to the port 19 is directed to discharge port 17 of the control valve unit and hence overboard. If however pressure is insufficient to open the relief valve then the coolant passing to port 19 is directed to the port 18 leading to the suction side of the pump. A priming valve is also provided in the control unit 16.
