Title: An articulated vehicle having hydraulic steering mechanism
IPC: B62D12/00
Filed: 1963-05-02
Abstract: 983,732. Articulated vehicles; hydraulic steering gear. CATERPILLAR TRACTOR CO. May 2, 1963 [May 31, 1962], No. 17341/63. Heading B7H. In an articulated vehicle having a rear section 10, with an engine and driving seat, pivotable relative to a front section 14 on vertical pins by double-acting hydraulic rams 20, the steering mechanism follow-up linkage includes an element 65 adjustable so that stops 77, 78 of the steering mechanism may prevent contact between the vehicle sections and a resilient link 64 to prevent damage to the linkage due to external forces acting to " jack-knife " the vehicle. In operation when the steering wheel is rotated to turn the vehicle, the steering shaft 47 slides along its axis in housing 48 due to thread 49 engaging an internal thread in nut 50 which is held stationary by sector 62. This axial shaft movement rotates levers 55, 57 together and hence moves rod 58 and valve member 59 to direct hydraulic fluid from control valve 60 to the hydraulic rams to steer the vehicle. As the two vehicle sections pivot relative to one another, link 64, which is pivoted to a pin 65 offset from the centre line of the front section 14, rotates lever 63 and sector 62 to move nut 50 axially returning shaft 47 and control valve member 59 to the neutral position to prevent further steering movement. The stops 77, 78 provided on shaft 47 limit movement of nut 50 and hence steering angle without preventing the follow-up linkage from operating and stops 75 are provided to limit relative rotation of the sections. Pin 65 to which link 64 is pivoted has adjusting nuts 80 so that it can be adjusted transversely of bracket 66 on the front section so that the stops 77, 78 operate before the stops 75. The resilient link 64 comprises a coil spring mounted between seats 71, 72, each of which abuts shoulders on both the rod 68 and cylinder 69 so that the spring is compressed whether the link is lengthened or shortened. Specifications 659,627 and 795,251 are referred to.

Abstract: 684,275. Spray-producers. ZAVALLONI, B., and VALDUCCI, F. June 29, 1951 [July 11, 1950], No. 17363/50. Class 69 (iii). A rotary sprayer comprises a barrel 4, with an outlet nozzle 3, Fig. 4, rotated on a fixed hub 6 by the impingement of water from the nozzle on to a turbine wheel 1 which drives a shaft 2. The rear end of the shaft has a worm 7, Fig. 2, which engages a wormwheel 8 in a casing 11, and the worm-wheel is mounted on a shaft 9 carrying an eccentric pin 13 engaging a hole in a plunger 14. The plunger is reciprocated in a recess 15 in a block 12, and the block is thereby reciprocated horizontally on the casing 11. Pawls 17, 18 are pivotally mounted on pins 16, 16a on the block and their upper ends are able to engage the teeth 19 of a circular stationary rack 20. A plate 24 is also pivoted to the block 12, and in its central position a finger 26, integral with the plate, holds the pawls out of engagement with the rack and the barrel remains stationary, although it may be turned by hand. By rocking the plate to one side, Fig. 1, one of the pawls comes into engagement with the rack, and with the reciprocation of the block the barrel is rotated step-by-step around the hub. By lifting this pawl and rocking the plate to the opposite side, the other pawl effects an opposite rotation. In order to effect a to-and-fro movement over a circular arc, two pins 23 are engaged in spaced holes in the rack, and when a lower projection of the active pawl strikes a pin the pawl is raised from rack engagement. A shoulder on this pawl contacts an integral finger 25 on the plate 24 to swing the plate downwardly to hold the pawl in its imperative position, and to disengage the other pawl which turns the barrel in the opposite direction. The hub 6 may include a series of cam surfaces 27, Fig. 4, which are engaged by a follower 28 secured to a rotatable rod 30 with a curved outer end 30a. The latter is thereby moved into the water stream to produce a greater impingement of water on the turbine wheel, which is driven faster. By suitable arrangement of the cam surfaces relative to the barrel rotation, rectangular areas can be covered.
