Abstract: An improved trimmer type road construction apparatus, particularly useful in applications requiring a high degree of maneuverability and control flexibility, which is steeringly controlled by turning a centrally disposed front track assembly in such a manner that the main frame can be raised and lowered relative to the front drive assembly without a loss of steering control; and which has an automatic steering, grade and slope control constructed to be automatically adapted to particular job specifications and locations. The trimmer also has a reclaimer assembly for removal of the excavated earth, the reclaimer assembly being automatically positionable to deposit the excavated earth in predetermined, controlled positions about the trimmer.

Abstract: An improved brake control apparatus automatically engaging the park brakes of a vehicle when the vehicle ignition switch is turned to the off position and automatically disengaging the park brakes of a vehicle when the vehicle ignition switch is turned to the on position.

Abstract: The present invention includes an improved tool particularly useful for effecting the removal of a shock absorber from the upper structural member of an automobile frame, having a base member and an insert member slidably disposed within an opening through one end of the base member. One end of the base member is retainingly disposed over the nut securing the threaded extension of a shock absorber to the upper structural member and the end of the insert member disposed within the base member opening is retainingly connected to a head portion of the threaded extension, the base member being held in a stationary position thereby securing the nut in a stationary position while the insert member is rotated thereby rotating the shock absorber via the head portion connected thereto. The tool of the present invention thus allows the shock absorber to be rotated to unthread the connection between the shock absorber and the nut which secures the shock absorber to the automobile upper structural member.
