Abstract: An adjustable-leg chair has four telescoping legs with provision for setting each leg at a desired length. The chair adjusts to very uneven terrain so that the user can sit in a generally level and comfortable position especially for fishing on the bank of a river or lake, uneven camp sites, graded spectator seating locations, etc. The folding aluminum chair has horizontal connecting braces extending across front and back at the bottom ends of upper leg sections which comprise tubes of the telescoping connection. When the lower extensions of the telescoping legs are fully removed, the chair serves as a beach chair with the connecting braces being the primary contacts with the sand or ground.

Abstract: A powered roller skate apparatus includes a motor supported on the back of a user, with a flexible drive extending from the motor to a front wheel truck for a standard roller skate. The wheel truck is interchangeable with that of any standard roller skate, and only one bolt need be removed and replaced to effect the change.Instead of an internal shaft to drive the one driven wheel, the wheel drive system includes a hub adjacent to the outside of the wheel, and a series of prongs extend from the hub directly into the side of the urethane wheel. Gear reduction from the motor is achieved through two angle drive gear boxes, one at each end of the flexible drive, which may include different-sized gears for the reduction, at the same time this enabling the flexible drive to be oriented generally upright between the skate and the motor.

Abstract: A carpet seaming roller tool for drawing two sections of carpet together in a hot melt adhesive seaming operation has two, separate, cleated rollers which are disposed side-by-side so that one roller grips one section of carpet and the other roller grips the other section of carpet as the roller tool is rolled back and forth along the seam during the seaming operation. Each roller has an axle which is mounted for rotation about a horizontal axis in its own support frame, and each support frame is mounted for a limited amount of pivotal, swinging movement (about a generally vertical axis) in a main frame associated with the handle of the carpet seaming roller tool.
