摘要： A reversible road scraper has two-edged blades that allow the scraper to be pulled in two different directions. The blades can be mounted on springs so that the scraper will not hang up on any objects that could potentially damage the scraper. Also, the scraper may include an edger blade to trim and define the edge of a road.

摘要： A method of working or shaping a surface in situ. The earthworking tool of the invention is engaged with the surface in situ and is propelled about the surface by the motive source. The motive source is capable of moving the apparatus in any direction on the surface while it is engaged in working the surface. The tool carrier assembly of the apparatus is pivotably attached to the motive source and may be urged to rotate about an axis that is somewhat perpendicular to the surface being worked. The earthworking tool may then be moved in any other direction desired, by the action of the motive source, without disengaging the earthworking tool from the surface being worked.

摘要： A road scraper includes a frame having forwardly positioned blades extending rearwardly and laterally for directing loose material against a rear blade extending angularly in the opposite direction between rearwardly extending side frame members thereby causing loose material on the road to be redistributed across the road under the rear blade on the back side of the frame. A rearwardly positioned dam blade cooperates with the rear angular blade to cause loose material to be accumulated and then discharged through a passageway between the rear end of the dam blade and the angular blade.

摘要： A mounting assembly for a shank including a shank holder having a passage for receiving the shank, the passage having at one end opposite tapering surfaces which define with the leading edge of the shank opposite tapering spaces for receiving wedge members. Bolts are provided between the wedging members and holder to urge the wedging members longitudinally of the passage to wedge the shank in a selected position relative to the holder.

摘要： An adjustment mechanism for use with farm implements or other equipment utilizes a series of alternating teeth and notches arranged in an arcuate pattern about an axis of adjusting movement on a movable member and a pair of arcuately spaced latching bars on a stationary member of the mechanism. The bars are individually shiftable into and out of engagement with the teeth and notches and are spaced apart such a distance that when either of the bars is in registration with a notch, the other bar is in registration with a tooth. Springs yieldably bias the bars toward the teeth and notches so that the bar aligned with a notch will snap down into the notch while the other bar resides in a standby position abutting the outer end of its tooth. When the seated bar is manually withdrawn from its notch, the movable member becomes unlatched and is free to be indexed one increment in either direction about the adjustment axis, whereupon the bar in the standby position snaps down into a notch brought under that bar, reestablishing a latched condition while the withdrawn bar becomes retained in its standby position by the outer end of its tooth. A double-acting lever having two fulcrum connections with the bars at their outer ends is successively raised and lowered about alternate ones of the fulcrum connections to manipulate the latching bars.

摘要翻译： 用于农具或其他设备的调节机构利用一系列交替的齿和凹口，其围绕可移动构件上的调节运动的轴线和在机构的固定构件上的一对弧形间隔的闩锁杆以弧形图案布置。 这些杆可以单独地移动进入和脱离与齿和凹口的接合，并且间隔开这样的距离，使得当任一个杆与凹口对准时，另一个杆与齿对准。 弹簧可屈服地将杆朝向齿和凹口偏压，使得与凹口对准的杆将向下卡入凹口中，而另一个杆处于与其齿的外端相邻的待机位置。 当从其凹口手动地撤回就座杆时，可移动部件变得松开并且可以围绕调节轴线在任一方向上自由地被分度一个增量，于是待机位置上的杆咬入到该杆下方的凹口中，重新建立 锁定状态，而退出的杆通过其齿的外端保持在其备用位置。 具有在其外端处的杆的两个支点连接的双作用杆在支点连接的交替的一个处连续地升高和降低以操纵闩锁杆。

摘要： A double disk C-spring standard assembly utilizes bearings mounted to a simple carrier plate. The plate is connected to the lower end of a single C-spring oriented in the fore-and-aft direction. Bearing assembly mounting holes in the plate define the necessary gang angles. Compact disk blade hub assemblies facilitate side-by-side mounting of the center bearing assemblies.

摘要： A tillage tool includes a relatively narrow shank that slices through the soil while a ripper point at its lower end fractures and lifts the subsoil. Minimum surface disturbance adjacent the opposite sides of the shank is assured through the provision of a pair of independently mounted down-pressure wheels on opposite sides of the shank that engage and apply constant downward pressure against soil tending to erupt at the top surface. Each down pressure wheel is mounted to the shank assembly by its own leaf spring so that the two wheels react to ground changes independently of one another and without adversely affecting each other. A guide plate associated with each leaf spring prevents twisting of the spring as it flexes and provides stops for limiting the opposite extremes of up and down flexing of the spring.
