Title: Improvements relating to motor vehicle brake system
Inventor: FERRIDAY JAMES REGINALD
IPC: B60T7/08
Filed: 1967-12-23
Abstract: 1,202,900. Speed-responsive pedal actuators for brakes. J. R. FERRIDAY, and R. G. COLLIER. 20 Dec., 1968 [23 Dec., 1967], No. 58569/67. Heading F2E. A motor vehicle brake system comprises a control member for use both when the vehicle is in motion and when it is parked; retaining means are adapted to engage automatically with the control member to retain it when it is actuated whilst parked; the retaining means is adapted to be disengaged from the control member to release the brake system by movement of a part of the vehicle; this movement is either in response to engine speed above a pre-determined value, or it is brought about by coupling the engine to the drive transmission. When the vehicle is parked, and the engine is idling or stopped, the brakes may be applied by depression of the pedal 16, Fig. 1. The pedal forms part of a bell-crank lever 10 having ratchet teeth 20, and the lever is maintained in the "on" position, after actuation, by engagement of a spring-loaded pawl 21 (spring not illustrated) with the ratchet teeth. The pawl 21 is pivoted at 22 to a bracket 12 on a frame member 13 of the vehicle. When the engine speed rises above a predetermined value, weights 34, Fig. 2, linked between a T-shaped member 33 (secured to the engine output shaft 27) and an annular flange 29 forming part of a driving pulley 26, fly outwards, pushing flange 29, and the slotted sleeve 31 integral with it, to the left. The slotted sleeve 31 rotates on a bearing 40 mounted on an axially movable spindle 41, which is pulled to the left by this movement of sleeve 31. A cable 25, Fig. 2, is consequentially pulled to the right, and since this cable is connected at 24, Fig. 1, to the pawl 21, the pawl is withdrawn from the ratchet teeth 20 and the brakes are consequently released.  Cable 17 is attached to the rear wheel brakes and cable 18 to the front wheel brakes. According to modifications, not illustrated, the pawl or other retaining means may be connected to a fluid-pressure-sensitive device at the induction manifold of the vehicle engine, so as to be disengaged from the bell-crank lever or other control member by movement of the device; or the retaining means may be disengaged from the control member by movement of the engine on its mountings as the engine is coupled, whilst running, to the vehicle transmission; or the retaining means may be disengaged from the control member by movement of a part of the vehicle's drive transmission.

Patent GB-610888-A (GB)
IPC: F23Q1/06
Abstract: 610,888. Electric igniters. FAULKNER, H. April 17, 1946, No. 11884. [Class 75(iii)] An electric igniter has two contacts m, n which are normally in engagement and are adapted to be separated by a solenoid v or relay to produce a spark. The solenoid v when energized by the closure of a hand or automatically operated switch attracts an armature u to release a rod t from a slot in a plunger s and allow a spring x to raise a lever q to lift the carbon contact n to which it is connected by a rod o and spring p. The raising of the lever q causes the depression of the plunger s which abuts against a lever y to separate contacts z, z<1> in the circuit to the contacts m, n, and break the circuit, this arrangement acting as a safety device. A resistance may be provided in series or in parallel with the solenoid, and a fuse or fuses may be incuded in the circuit.
