Abstract: 1,245,509. Fluid pressure brake systems. ROBERT BOSCH G.m.b.H. 21 Nov., 1969 [22 Nov., 1968], No. 56982/69. Heading F2F. A brake system for a motor vehicle in which the brake cylinders 11 are spring applied, fluid pressure released, a reservoir 1 supplies fluid pressure by way of a brake valve 5 to a release valve unit 6 which has a check valve 8, 9 controlling fluid pressure to the brake cylinders in normal braking operation, and a further valve comprising a seat 19 and piston 15 which has flaps 17 yieldable under fluid pressure to allow fluid to pass from a second reservoir 2 by way of an auxiliary valve 23 to the brake cylinder 11 to release the brakes if the pressure in brake line 6 fails. Auxiliary valve 23 has a lever 40 which, when moved into the position shown in dotted lines, causes a lug 38 of a shaft 37 to engage a recess 39 of a piston 35 which forces a further piston 32 engaging a tube 24 downwardly a valve member 26 disengaging a seat 27, to allow fluid pressure to release the brakes. If the fault in line 6 is remedied actuating lever 40 is automatically returned to its original position as fluid pressure from an auxiliary line 43 forces pistons 32 downwardly, a return spring 41 engaging the lever being released to free lug 38 from recess 39. With the lever in its orginal position fluid pressure in line 22 is vented by way of the bore of the tube 24 and chamber 31. In a modification of the auxiliary valve which is push button operated in emergency release action the valve is mechanically held open all the time. In a modification of the release valve two piston cheek valves controlling lines 6 and 22 respectively, are joined by a member having a throttled bore partly through which air can be released from the auxiliary valve 23 when the defective line 6 is closed.

When the hedgecutter meets an obstruction the carrier 11 pivots about one of the axes 37, 38 disengaging one of the balls 26, 27 from its socket and thereby raising the draft links. A bar 14 engages the lower draft links to limit pivotal movement of the assembly 10. Sockets 22 and 24, 25 of the joints are on post 18 and beam 20 respectively and balls 23, and 26, 27 are on beam 13 and beam 15 respectively. Between plates 31, 32 is pivot pin. 33 on which is pivotably mounted side-arm 34 of a hedge cutter. Hydraulic ram 35 is pivotally connected between element 21 and pivot pin 36 so that the vertical setting of the hedge cutter can be adjusted. The path which the hedge cutter follows when deflected can be varied by adjusting the fore and aft position of balls 26, 27 so that axes 37, 38 are no longer vertical when viewed from the side. The cutter may be deflected upwardly, or downwardly, and the cutter can be positioned either to the left or to the right of the structure by operation of ram 35. In an alternative arrangement not shown the ball and socket connections are replaced by two hinge assemblies arranged between carrier 11 and assembly 10 on axes 37, 38 respectively, and one or another of the hinge assemblies may be manually disconnected so that pivoting can take place about the other hinge connection. Another embodiment is described (Fig. 4) in which the assembly is in the form of linkage lift frame 53 with bosses 54, 55 for attachment to the draft links, and adjustable abutments to limit forward pivoting of the frame relatively to the links. The frame also carries ball 58 and sockets 62, 63. The carrier part consists of pillar unit 64 with balls 65, 66 and socket for ball 58, and plates to receive the upper link. The pivot axes are 78, 79 and the path followed by the hedge cutter when it is deflected can be varied in a manner similar to that mentioned above.
