Abstract: An earthworking tip suitable for mounting on an adapter which is wedge-shaped in vertical cross section. The tip defines a rearwardly facing V-shaped projection which mates with a V-shaped opening in the adapter to transfer loads from the tip to the adapter. The tip has rearwardly extending upper and lower flanges to generally mate with the wedge-shaped adapter. Retaining means secure the tip upon the adapter.

Abstract: The elevator of a self-loading earth-moving scraper is moveable as a unit relative to the bowl thereof and automatic controls are provided which shift the elevator at predetermined stages in the operating cycle of the scraper. The automatic controls operate by sensing forces which react on other components of the scraper and which are indicative of the need for shifting the elevator. The elevator may, for example, pivot gradually upward as loading progresses or may be raised substantially prior to load ejection without requiring control of these movements by the operator.
Abstract translation: 自载式土铲装置的升降机作为一个单元可相对于其碗移动，并且提供了自动控制装置，其将电梯在刮刀的操作循环中的预定阶段移动。 自动控制器通过感测对刮板的其它部件作出反应的力并且指示需要移动电梯来操作。 例如，升降机可以在装载进行时逐渐向上枢转，或者可以在加载弹出之前基本上升高，而不需要操作者控制这些运动。

CPC classification number: E02F3/8157
Abstract: A mounting and control arrangement for supporting a bulldozer blade upon a tractor by means of a C-frame. The blade is centrally secured to the C-frame by a universal ball joint. Hydraulic angling jacks are interconnected between each leg of the C-frame and a guide member slidably mounted on a T-shaped bar respectively secured to each C-frame leg. A triangular brace supports each end of the blade and is secured to the respective guide members by a ball joint. The angling jacks are pivotally connected to the C-frame legs and the guide members by means of ball joints to reduce stresses with the pivotal connection between the angling jacks and the guide members preferably being a trunnion mounting having a pivot axis perpendicularly related to the axis of the pivot joint between each angling jack and the C-frame.
