Title: Full-power hydraulic braking systems
IPC: B60T13/22
Filed: 1973-11-19
Abstract: 1437097 Dual hydraulic braking systems; valves CLAYTON DEWANDRE CO Ltd 14 Nov 1974 [19 Nov 1973] 53530/73 Headings F2F and F2V An hydraulic braking system comprising two independently-powered circuits serving separate sets of brakes under the control of a common pedal-actuated dual valve 4 includes a spring brake actuator 14 fed from both circuits through separate lines each incorporating a pressure responsive protection valve 16 operable in the event of failure in the related circuit to cut off that circuit from the spring brake circuit whereby the latter continues to be fed from the other circuit. Each protection valve comprises a housing having inlet and delivery ports 22, 23, a spring-loaded valve element 24 and an annular seating 25 the element 24 being pushed off its seating when the fluid pressure exceeds a predetermined minimum. At the upper end of the housing a spring-loaded disc valve element 26 controls flow between ports 27, 28, a stem 29 on the element 24 abutting the element 26 so that it is lifted in unison with the valve element 24. A stem 26a on element 26 slides in a blind bore 30 and a solenoid 32 the circuit of which is controlled by low liquid level switches in a reservoir 2 has an armature sliding on the stem 29 and normally held out of engagement with a shoulder 34 on valve element 24 in opposition to a loading spring 35. Upon failure in either circuit elements 24 and 26 will close but the spring brake system will be fed from the other circuit. If a leakage occurs in the spring brake system valves 24 may allow slight flow until operation of the level switches breaks the solenoid circuits to allow extra spring loading to close the valves. Similarly an external leakage will cause both valves to shut off all flow to the spring brake circuit. The circuits also include low pressure switches 17 which actuate warning buzzers.

Vacuum and/or pressure may be used in addition.  The clamp comprises two similarly shaped plates 4a, 4b which are hinged at 4c and which have edges 4d conforming closely with the outline of the mould 2 in the forepart region. To locate the upper in the clamp 4, a row of pins 18 is fixed to the lower plate 4b around the edge 4d and spaced from the edge a distance equal to the width of the lasting margin 22. Each pin 18 extends into an aperture 20 in the upper plate 4a when closed. The mould 2 is mounted on an arm 8 which is pivoted at 12 and movable by a link 14 attached to a fluid actuator so that, in operation, there is both relative bodily and relative rotary movement of the clamp 4 and the mould 2, with the mould entering the upper back part first. When the mould has fully deformed the upper, the upper is allowed to set into shape; if the upper is leather the mould may be heated and if the upper is poromeric the mould may be cooled for this purpose.  The preformed upper may then be transferred to a last for the attachment of an insole and a post-setting operation if required. The outsole is then attached to the upper/ insole still on the last or in an injection moulding machine. Alternatively, the upper may be directly string lasted on the foot of  an injection moulding machine for the attachment of insole and outsole. The mould 2 is made by vacuum forming a sheet of p.v.c. on to the last, removing the resultant shell, flattening the shell somewhat in the forepart regions to remove re-entrant portions and producing the mould 2 from the shell e.g. in metal by foundry techniques.
