  • Patent number: 5579595
    Abstract: A stretcher bar frame for artists' backing material and kit to make same. Lengths of lumber rails of conveniently available standard sizes, such as 1".times.3" and 2".times.4", can be used with a plurality of molded corner bracket units, each having two channels sized to receive, and completely enclose the outer side walls of, the lumber rails. In a first embodiment, the corner brackets units have a bead region extending around their upper and outer perimeter. In other embodiments, separate bead members are provided, which can be cut to a desired length, for fixable attachment to the lumber rails to form a continuous bead region around the perimeter of the stretcher bar frame, such that when the backing material is stretched over the front of the stretcher bar, it rides on the outer perimeter bead, and not on the stretcher bar frame.

  • Patent number: 5546986
    Abstract: A leakproof dual action valve which is operated by its relative state of engagement and disengagement to a complementary, mating spring-actuated valve connected to a fluid supply. The dual action valve has a sleeve member, a piston carrier portion, a piston body, and a valve. As the sleeve member of the dual action valve is screwed onto the mating spring actuated valve, the piston body simultaneously pushes open both the dual action valve and the spring actuated valve. When the sleeve member is unscrewed from the mating spring actuated valve, both valves close, thereby preventing and leakage of fluid. The dual action valve is adapted to connect to a vacuum hose, which will evacuate any fluid from the fluid supply.

  • Patent number: 5542245
    Abstract: This disclosure relates primarily to the making of compressed single and double arrow jewelry chains, of precious or non-precious metal, and other unique surface designs, from open link chains wherein the regularly repeating apertures of the prior art chains have been substantially eliminated, thereby providing an exceedingly smooth look and silky feel to the completed chain. The compressed chain of this invention is made by first precisely aligning two or more open link chains together, side by side, along a single longitudinal axis, welding, as by soldering or brazing, the aligned open link chains, and subjecting the thusly aligned chains to a series of incremental compression steps, along the longitudinal axis of the aligned curb link chains. In this way, the regularly repeating apertures of the aligned open link chains are substantially eliminated while creating, as in the case of the use of single curb chains as the starting point, novel non-apertured arrow designs.

  • Patent number: 5518315
    Abstract: An external bag support frame for attachment to a bag with side walls and a bottom wall. The external bag support frame has perimeter walls for attachment to the bag's side walls by stitching, adhesive, or with detachable means such as hook and loop material. The frame provides the bag with additional rigidity and abrasion resistance. In one embodiment, webbing straps passable through slots in the perimeter walls provide bottom support for the bags bottom. In another embodiment, a bottom grid, unitary with the perimeter side walls, form the bottom support for the bag.

  • Patent number: 5471769
    Abstract: The invention is a single hand operation shoe lacing system which has an elongate lace strap which is affixed at its front end to a lacing area of the shoe in the vicinity of the vamp. The lace strap is looped through a series of lace strap loops positioned in the lacing area of the shoe, alternately on the medial and lateral quarter panels of the shoe. The rear end of the lace strap adjustably carries a first engagement member with a second engagement member being positioned on the counter of the shoe. The first engagement member is adjustably positionable on the lace strap to adjust its working length. When the first engagement member is engaged with the second engagement member, the lace strap will draw the medial and lateral sides of the quarter together, and thereby fit the shoe to the wearer's foot, and when the first and second engagement members are disengaged, the medial and lateral quarter panels of the shoe can be separated, and thereby loosen the shoe on the wearer's foot.
