Abstract

1307881 Automatic control of steering and height C P MILLER AR MILLER and D J MILLER 8 April 1970 16806/70 Heading E3R [Also in Division E1] A machine for extruding material 52 onto a surface adjacent a guide line 182 comprises a body supported by lifting means 70, (72), 74, 76 on steerable members 120, means 194 sensitive to the direction of the guide line controlling steering of the members, and means 192 sensitive to the elevation of the guide line controlling the raising and lowering of the body. Material is supplied via hopper 12, conveyor 18, hopper 24 to open-end form 30 fixed to frame 32. Reinforcing rods 46 are fed into the front of the form 30. Means 192 comprises a fork 196, deflection of which by the guide line closes switches in the circuit of a solenoid valve which controls supply of fluid to the cylinders of hydraulic ram lifting means. The cylinders are attached to frame (32) and the rams to bogies of crawlers 120. The height of the form 30 is thus adjusted. Rams 74, 76 are connected to the bogies via pivot (128) on a beam (124). Means 194 comprises a fork, deflection of which operates a solenoid valve controlling supply of fluid to hydraulic rams 162, Fig.5, (not shown), connected between the bogy and a tie bar (150). Rotation of the bogies and crawlers about a vertical axis is thus effected. The fork 194 is connected by slidable rods 210, 206) and cables (230, 242) to rods (240) on the ram (104), so that steering of the crawler moves the fork transversely. The crawlers at a respective side of the vehicle are driven at the same speed by hydraulic motors in series.
