Abstract

307,817. Allen & Sons (Oxford), Ltd., J., and Allen, G. W. G. Dec. 14, 1927. Hydraulic and pneumatic transmission.-Comprises power or relay steering-gear having valvecontrol means formed in two parts and means interposed between the ends of the parts for varying the effective lengths of the parts. In the construction shown in Fig. 1 a steering roller 6 is controlled by a piston 1 in a cylinder 2 the distribution of steam to which is effected by a valve 18. The valve is controlled by a hand-lever 16 and a spring 23, and the valve-rod is made in two parts 15, 17 separated by a wedge 11 carried by a bell-crank lever 9 connected to the piston rod 3. Thus, when the hand-lever is operated the valve is moved to admit steam to one side or other of the piston, the piston is moved and rotates the roller 6 and also adjusts the wedge 11 between the valve-road parts until the valve is returned to its central or cut-off position. Modifications are described in which (1) a cam is inserted between the adjacent ends of the valve-rod parts, (2) a togglelink connection is provided between the handlever and the valve, the toggle being broken or straightened by a link connected to the steering gear, and (3) one part of the valve-rod is formed as a sleeve on the other part, this sleeve carrying a sliding wedge actuated by the steering-gear. The invention may be applied to a vehicle having a steerable endless-track as described ih Specification 259,667, [Class 79 (i), Locomotives &c.].
