  • Patent number: 7431314
    Abstract: A wheeled hand truck installs, removes, and transports rim-mounted tires and brake drums for vehicles. The truck comprises an elongated frame and extended fork section supported by a transverse axle having wheels at the ends bracketing the frame. The frame includes a handle section extending opposite the fork section that terminates in a grip. The fork section extends opposite the handle for straddling beneath a tire or drum on both sides of its center of gravity. The tire rests against the handle portion and fork, while the drum is mounted in a movable cylinder. The tire or drum is transported by balancing the weight of the tire on the wheels while pushing on the grip. The truck also has an extended lift step for providing leverage, a kickstand, an oil catch pan for brake drum drips, and grab pins for spoke-type hub and drum assemblies.

  • Publication number: 20020078624
    Abstract: A tree support holds the tree in the desired orientation until its root system can hold the tree in that orientation without the need for additional support. The tree support includes a collar and three or more legs. Positioning screws carried by the collar advance radially inward toward the trunk of the tree to engage the trunk and thereby hold the collar in place. The outer ends of the positioning screws are capped with ornamental medallions. The medallions can carry any design or, for example, initials or information about the tree. One embodiment of leg for the tree stand, is a telescoping, rigid leg that pushes against movement of the tree away from normal orientation. The other embodiment of the leg uses tension on wires connected to anchor screws inserted into the ground to hold the tree upright.
