Abstract

1414185 Dozer-bucket assembly ROME INDUSTRIES Inc 26 Oct 1972 [23 Nov 1971] 49397/72 Heading E1F An earth moving assembly comprises a bucket 30, a bulldozer blade 80, and a power operated linkage operable to move the blade from a position in which it forms a rear wall to the bucket (Fig. 4, not shown), through intermediate positions to function as an earth ejector, Fig. 5, to a bulldozer operating position, Fig. 6, in which the blade's leading edge is moved in front of and below the leading edge of the bucket and positively engages the bucket. The blade is joined to the top of the bucket by links 102 and is pushed forwards by the action of a hydraulic unit 150 acting on a crank arm 116 which is joined by links 113, 120, 121 to the bucket. The links 120, 121 are pivotally joined at 122 and are normally urged by spring 128 to the position shown in Fig. 5; but, as an abutment edge 95a on the blade slides over the bucket edge, a set screw 133 on the arm 116 causes relative movement of the links about 122. This has the effect of drawing the lower edge of the blade to the rear to positively engage portion 95 against the bucket edge. Fig. 7 shows a modification of the operating mechanism: the crank arm 116 directly engages a slot 182 in an arm 180 fixed to the blade, is normally urged to the top of the slot by spring 183, and slides down the slot drawing the blade to the rear for bulldozer operation. In a further modified control link arrangement (Figs. 8-12, not shown) screw threaded members are incorporated to allow adjustment of the position of top link axis 103, and of the length of the link 121.
