Title: Improvements in or relating to brakes of motor and trailer vehicles
IPC: B60T13/74
Filed: 1943-04-27
Abstract: 564,866. Vehicle brakes. PATENT LIGHTING CO., Ltd., and SPENCER, T. D. April 27, 1943, No. 6647. [Class 103 (i)] Common operating means for a trailer brake system of the kind in which the braking effect increases with the displacement of an actuating member and a tractor brake system of the kind in which the actuating member is movable against a low initial resistance and then as the brake becomes effective, against an increasing resistance, includes a spring device which prevents or limits to a small amount movement of the actuating member of the trailer brake until the high resistance stage of the tractor brake actuating member is reached, thus ensuring that the two systems come into action at substantially the same time and to a corresponding degree. As shown, a trailer vehicle is provided with electromagnetically actuated wheel brakes of the Warner type energized by a controller 20 and the tractor with hydraulic brakes comprising a master cylinder operated by a pedal 14. The controller 20 comprises an arm movable over variable resistance contacts to graduate the braking action, this arm being operated by an external arm 41. An arm 34 mounted on a fixed pivot 32 engages by its end 35 the pedal 14 and is pivoted at 37 to a floating lever 36 connected bv a link 40 to the controller arm 41 and having a pedal end 38. The link 40 is slidable through a pivot 52 on the arm 41 and a spring' 53 abuts on this pivot and upon a nut 54 on the link to permit lost-motion between the link and the arm after the arm has been moved to its extreme application position. Relative movement between the lever 36 and arm 34 except to a small extent, is resisted by a spring 42 interposed between caps 45, 47 on a link 43 connected at 44 to the arm 34, the cap 47 being slidable on the link and being engageable by a projection 49 on the lever 36. The initial compression of the spring is adjustable by nuts 50. Normally, there is slight clearance at 56 between the projection 49 and cap 47. When pressure is applied to the pedal 38 the controller 20 is initially operated to an extent permitted by this clearance to give a light application of the trailer brakes. During further movement of the pedal 38, the lever 36 and arm 34 move together so that the pedal 14 is operated but not the controller 20, and as the tractor brakes become effective the spring 42 yields, the lever 36 pivots relatively to the arm and the controller 20 is actuated to increase the trailer brake application. The trailer may be the rear portion of an articulated vehicle. The tractor brake system maybe of the kind in which displacement of the actuating member over the low resistance range brings a servo-device into operation. According to the Provisional Specification, the front end of the floating lever may co-operate with a fixed cam to cause this end to be depressed upon initial depression of the pedal to effect the initial light trailer brake application and the controller may be fixed on the rocking lever.

Title: Improvements in and relating to locking devices for closet and lavatory doors
IPC: G07F17/14
Filed: 1929-03-05
Abstract: 329,726. Krasselt, R. O. March 5, 1929. Stays.-A lavatory or closet door of the type held in a semi-open position, when the lavatory or closet is unoccupied, by a spring-pressed bolt a engaging a hole or socket g in a guide rail d fixed to the door frame is fitted with a coin-controlled bolt operating mechanism comprising a hand-operated spring-pressed bolt k which is coupled to the bolt a by a coin z. The coin z on insertion in the coin shoot falls into a slot h' in a block h attached to the bolt a and rests between the slanting nose pieces of stepped latching links o which are pivoted on a plate arranged below the bolts a, k and are pressed towards one another by springs f against stops. On turning by hand a shaft m the bolt k is drawn back and by the engagement of a projection k<1> on the bolt k with the coin 2 the bolt a is withdrawn from the socket g, thus allowing the door to be opened and the compartment entered. The movement of the bolts a, k causes the coin to slip over the nose on to the first steps of the links o, in which position (shown in Fig. 3) the coin is retained when the shaft m is released. The door is closed on entry by a spring, the partly retracted bolt a passing over a slide p on the rail d and being fully retracted when the door is fully closed by riding up an inclined part d' of the rail, thereby causing the coin to be moved to the second steps of the latching links, where it is released. When the door is again opened the bolt a pushes the slide p until it is retained by a pin p<2> over the socket g so as to prevent the bolt from entering the socket. When the compartment is vacated the door is closed by its spring and the bolt a displaces the slide p so that it engages in the socket g. The insertion of objects to keep the bolt from entering the socket g is prevented by providing at the end of the guide rail a slotted housing a<3> filled with a channelled angular flap x which is pivoted on a pin y so that the slot in the housing and the entrance to the flap normally register. A squared spindle 7 is connected to the bolt a by links and levers to allow the bolt to be operated by the attendant by means of a socketed key without the insertion of a coin.
