Abstract: 1,267,694. Brake valves. DR. HERMANN E. MULLER. 25 Aug., 1969 [11 Sept., 1968], No. 42212/69. Heading F2F. In a valve mechanism for intensifying the braking force in motor vehicles in which a pneumatic piston 3 separates an air chamber B and a vacuum chamber C connected to the vehicle engine suction, there is a first valve position in which the chambers are cut off from each other and a second valve position in which air is passed to air chamber B from a further chamber A to operate the piston. The valve comprises two slides 8, 9 engaging an expansion spring 12 and slidably engaging a control member 7 coupled to a brake plunger 6 and having stops 14, 15. In the inoperative position shown B and C communicate through a port 18 and a channel extending between the valve slides and valve casing 1, 2. On depression of plunger 6 stop 14 engages slide 8 and stop 15 presses against a compression spring 19, slide 9 disengaging slide 8 and moving downwardly under the action of spring 12 and a seal 17 engages casing 2 to cut off chamber B from chamber C. On further depression of plunger 6, slide 8 also moves downwardly and a seal 16 disengages casing 1 to allow air to pass from A into B to operate the piston.

Abstract: 1,235,722. Retractive switches. K. MAECKER. 5 Sept., 1968 [15 Sept., 1967], No. 42340/68. Heading H1N. In a snap-action switch with a magnet to hold the contacts until a snap-spring 10 is sufficiently strained the permanent magnet 1 and its polepieces 2, 3 form a tube surrounding a sleeve 6 containing armature rings 5, the sleeve 6 when actuated moving along the tube with the stops 7, 8 for the sleeve 6 located outside the magnet system. As shown, snapspring 10 presses against a movable stop ring 11 bearing against sleeve 6, a rebound spring 13 bears against a movable stop ring 14 also bearing against sleeve 6, and a retracting spring 16 bears against a ring 18 attached to plunger 9. Sleeve 6 carries moving contacts 20, 21 co-operating with fixed contacts 23, 24. Plunger 9 is moved to the right by cams or levers (not shown) on a machine, but sleeve 6 is held in the position shown by the magnetic force. As plunger 9 moves to the right, snapspring 10 is strained until the combined force of spring 10 and contact spring 22 is sufficient to overcome the magnetic force, and the sleeve 6 is snapped to the right against stop 8. When the external operating force is removed, the sleeve 6 is snapped back again by retracting spring 16, straining spring 13 until the magnetic force is overcome. Stops 7, 8 are adjustable. To adjust the magnetic force, a shunt 28 can be screwed in or out to vary airgap 29. In a second embodiment, Fig. 4 (not shown), one fixed and moving contact are on the left-hand side of the magnet system, each moving contact being provided with a contact spring.

Abstract: 1500297 Automatic parking brakes CATERPILLAR TRACTOR CO 16 Oct 1975 [18 Feb 1975] 42499/75 Heading F2F A vehicle parking brake is of the kind which provides for automatic application in the event of an engine shutdown, a hydraulics failure or an electrical failure while allowing the driver to set the parking brake manually at any other time. In a preferred embodiment responsive to engine oil pressure actuator 10 is supplied by pump 22 check valve 24 and is controlled by a two position solenoid operated control valve 30 biased by spring 32 to a "brake set position", The driver controls operation of valve 30 through switch 44 which is normally spring biased to a neutral conducting position but is manually actuatable to "brake set" and "brake released" positions S and R respectively. Detection of sufficient engine oil pressure when starting up by operator 46 closes a switch 42 and subsequent movement of the switch 44 by the driver to position R releases the parking brake by charging gate 68 of a silicon controlled rectifier SCR for conduction to energize solenoid 38. The circuit also includes pilot light 62 which lights whenever the parking brake is set. In a second embodiment an additional switch included between switch 44 and the solenoid 38 is coil operated and in a third embodiment the switch 44 is coil operated between only two positions S and R, the coil being connected between the R terminal and the low potential side of the circuit.
