Abstract
754,009. Shovelling machines. DRAIZE SOC. ANON. March 25, 1954 [March 26, 1953], No. 8788/54. Class 68(1) A scoop-arm loader has a scoop 8 carried, at each side of the loader, by two booms 10, 14 to which the scoop is pivotally connected at different points 9, 17, so that the scoop remains parallel to itself during raising and lowering of the booms. Boom 10 is pivotally connected at B to a lever 11 pivoted at A on the loader frame 7, and at C to a link 13 pivoted at D on the loader frame so that when lever 11 is rocked through almost 90 degrees by a cylinder 22 whose piston rod 21 is connected at 20 to the lever, boom 10 is moved through almost 180 degrees. Boom 14 is pivotally connected at 28 to a lever 18 pivoted at 19 on the loader frame so that the scoop can be tipped by operation of cylinder 26 whose piston rod 25 is connected at 24 to lever 18. A, load can be carried from a digging position in front of the tractor either to the unloading position shown or to a second unloading position behind the tractor, the scoop being tilted for dumping or for bringing it into the digging position in all three positions by operation of cylinder 26. The arrangement is such that angle # is less than 180 degrees in the digging and forward unloading positions of boom 10, being about 90 degrees in the latter position /where most tilting movement of the scoop is required, so that outward movement of piston rod 25 tilts the scoop clockwise, whereas in the rearward unloading position cc is,about 270 degrees so that the scoop is tilted anticlockwise by such movement to deliver rearwardly.
