Abstract: A highway marker for implantation in a highway or roadway where a top surface of the marker is just above the roadway surface and is centered in a stripe that separates the lane or roadway from the lane or roadway shoulder. The highway marker includes an outer sleeve formed from a section of five inch steel pipe that is for installation in the road with its top edge level with the road surface and contains a steel core centered in the sleeve in rubber that extends to the inner surface of the outer sleeve, the bonded rubber tending to deflect downwardly and rebound when a force is applied onto the steel core.

Abstract: A piston of a hydraulic ram, actuator or the like for fitting onto an end section of a straight rod with the assembly for fitting into to travel along a center cavity of a cylinder under the urgings of fluid under pressure that is introduced into that cylinder, the invention consisting of a number of piston component elements including upper and lower piston halves; retaining ring sections or halves, that are for assembly as rings in retaining ring grooves that have been formed around the rod end; at least one O-ring groove that includes an O-ring seal fitted therein; a piston spacer; a seal; and a pair of piston bearings, one for fitting over each piston half. In a practice of the method of the invention to assemble a piston onto a rod end, the piston component elements are sequentially fitted together to assemble the piston Which piston assembly can be accomplished in the field by even an untrained operator using only their hands, or using a minimum hand tools, such as a screw driver.

Abstract: The present invention constitutes a carrier for maintaining a spare tire to a vehicle, such as a pickup truck so as to be easily accessible, that comprises a lifting arm assembly which is secured to the vehicle bumper or frame and incorporates a screw arrangement therewith. The screw arrangement is turned manually and operates through a linkage to raise or lower a support bar assembly that mounts a platform whereon the spare tire is maintained. The lifting arm assembly can be pivoted to move the platform and tire between a storage area beneath the vehicle frame and to a point beyond the vehicle bumper whereby the tire and platform can serve also as a step for facilitating entry into the back of the truck or into a camper mounted thereon.
