  • Patent number: 4011638
    Abstract: A joint clamp particularly useful in joining braces of the type used temporarily to brace concrete slabs employed in tilt-up construction. The clamp can be installed onto a cylindrical brace without the employment of tools and without access to either end of the brace. It comprises, as a principal component, a tubular member that defines an opening having a generally cylindrical cross-section corresponding to the cross-sectional size of the brace. The wall forming the cylindrical opening is formed with a helically extending slot having a width, in an oblique direction, slightly larger than the cylindrical brace so that the clamp can be placed on the brace in an oblique position and then twisted into parallelism with the brace to snugly embrace the brace. The tubular member carries one or more secondary clamps for securing cooperating secondary brace members thereto.

  • Patent number: 4006501
    Abstract: A water bed mattress comprised of upper and lower flexible sheets which are provided with peripherally extending downwardly and upwardly struck flaps, respectively, at their outer peripheral ends. These flaps are sealed to each other in order to form a completely enclosed mattress. A tapered, angularly struck inner peripheral wall extends effectively between the upper and lower walls of the water bed mattress in such manner that the upper end of the inner peripheral wall extends to the outer peripheral margin of the upper wall and the lower end of the inner peripheral wall terminates inwardly of the outer peripheral margin of the lower wall. In this way, the inner peripheral wall operates in conjunction with the upper wall in order to form an inner water chamber which is essentially coextensive with the entire upper surface of the upper wall. An air chamber is formed by the other side of the inner peripheral wall, the outer wall and the lower wall.
