Abstract

858,421. Earth-excavating equipment. MIDWESTERN INDUSTRIES Inc. April 9, 1957 [April 9, 1956], No. 11461/57. Class 68(1). The king post 44 of a tractorcarried, earthexcavating equipment, e.g. a shovel unit, is vertically supported between beams 28, 30 on a frame 10 secured to the rear of a tractor and has opposite the pivotal connection 56 between the shovel boom 54 and the post 44 an arm in the form of three parallel spaced plates 50. Between the arm and each side of the frame is pivotally connected a doubleacting jack 72, 74, the jacks controlling the rotation of the king post. The piston rods 64, 66 of the jacks may be connected to the arm at a number of positions by a pivot pin 68 passing through aligned bores in the plates at these positions and in the piston rods.
