Title: Improvements in or relating to tipping vehicles or dumpers
IPC: B60P1/06
Filed: 1949-08-04
Abstract: 673,096. Vehicles carrying tipping skips. PENN, O. S. July 14, 1950. [Aug. 4, 1949] No. 20303/49. Class 78 (iv). [Also in Groups XXXI and XXXII] The tipping body of a mechanically propelled vehicle is supported over a pair of steering road wheels by a transverse axle or support which is swivelled, to steer the vehicle and to turn the body for tipping towards either side of the vehicle, by a steering mechanism which is either reversible or has a very low mechanical efficiency in the reverse direction. The tipping body 24 of the vehicle shown is carried on an axle-frame 3 carrying the front wheels 4 and pivoting for steering about a central vertical axis 6. When a catch 33 is released the body tips by gravity, rolling forward on rails 25 fixed to the axle frame and engaging runners 27 on the body. It is guided during tipping by links 26, the downward movement of which is limited by stops on the axle-frame, and its movement about the pivots 28 of the links 26 is limited by a loop-shaped link 29 pivoted to the body and embracing a bar 30 on the axle frame. Movement of the link 29 relatively to the bar 30 is limited by pins 31. The catch 33 is spring-biassed so that when the body is raised from its tipped position by a handle 32 the catch automatically re-engages a pin 34 on the body. It may be moved to release this pin by depressing a pedal bar 37 shaped as an arc about the steering pivot 6 and secured to the shaft 35 of the catch 33. The steering movement of the axle frame 3 is communicated from a steering wheel 46 through an irreversible or almost irreversible transmission 43 such as a worm and wheel, a screw and nut, or a hydraulic or other poweroperated system. The axle frame 3 is steadied against fore-and-aft rocking by engagement of a shoe 40 on the chassis with a guide rail 42 formed as an arc about the steering pivot 6. Lateral rocking to accommodate irregularities in the ground is permitted by a pivot 41 between the shoe 40 and the chassis, and a pivot 38 connecting the frame to the chassis and provided with a resilient sleeve 39 prevents interference from the eccentricity of the two pivots. A platform or other form of body may be provided instead of that shown. The rear wheels of the vehicle are driven through a belt transmission coupled and uncoupled conjointly with operation of the brakes by a pedal which may be locked in its operated position by a manually set ratchet.
