    摘要： Motor graders have a longitudinal main frame which carries a circle mounting bar that pivots on a horizontal axis at a connecting end and that has a carrying portion remote from its connecting end. A circle rotates on a vertical axis on the mounting bar carrying portion, and a grader blade is mounted on the circle. The present improved circle mounting bar is a box-like beam with internal vertical webs, and the beam increases in width from its connecting end toward a carrying portion of box-like cross section which is a separate part integrally welded to the beam. The shape of the beam in plan is intermediate between an isosceles triangle with its apex at the connecting end and a parabola with its apex at said end so as to give optimum uniformity of stress, throughout the length of the mounting bar, to both vertical and lateral forces.

    摘要： An electric motor-powered linkage is provided for raising and lowering an implement mounted on a lawn and garden tractor. The energization of the motor and preselection of the position to which it is desired that the motor move the implement is accomplished through means of a control system including a pair of side-by-side arms pivotally mounted for swinging movement about a common axis. On one arm is mounted first and second normally open control switches forming part of a control circuit connected to a motor-reversing power circuit, and on the other arm is mounted a cam forming part of a follow-up linkage. To selectively actuate the motor to drive in forward and reverse, the arm on which the control switches are mounted is selectively manually swung in opposite first and second directions to cause the first and second switches to be respectively actuated to closed positions by first and second arcuate surfaces of the cam. The follow-up linkage acts in response to motor actuation to return the cam to a position wherein the surfaces thereof permit whichever one of the switches is actuated to return to its normally open position to thus de-energize the motor. The cam surfaces are elongated in the direction of movement of the switches so that the distance through which the motor must move the implement in order to effect deenergization of the motor may be preselected by the amount that the switch carrying arm is manually displaced.

    摘要： The disclosure is of a heavy duty ball and socket trunnion for the working arms of an earth moving vehicle. There is a two-piece casing, each section with a recess to accommodate one segment of a split bearing, together forming a spherical bearing cavity. A pin which is to be welded to the frame of the vehicle carries a replaceable trunnion sleeve with a spherical outer surface complementary to that of the bearing. One section of the casing is to be welded to the end of the vehicle pusher arms. The casing completely encloses the bearing segments and the trunnion on at least three sides.

    摘要： The invention comprises a substantially hook-like materials gate including a moldboard wall, a collector wall and materials wall disposed distally at one of the terminal ends on the materials engaging side of a moldboard of a commonly known motor patrol, and a materials diverter carried between the moldboard and the moldboard wall of the materials gate. The materials gate may be operable to be selectively raised and lowered relative to the moldboard of the motor patrol in response to fluid or air under pressure supplied from a suitable source by means such as hydraulic or pneumatic cylinders.
