  • Patent number: 6785977
    Abstract: Measuring and leveling device for allowing objects such as but not limited to picture frames, mirrors, and paintings, and the like, to be correctly aligned when being hung from a wall. One embodiment includes an elongated non planar shaped body having a flat rear surface for being placed against the wall and a front raised surface having calibrating indicia. The elongated bar can have at least two different measuring units placed thereon for allowing the user different readable measurements such as metric, inches, and the like. The slidable carriages have leveling gauges such as bubble gauges. The gauges can be interchangeable so that different orientated gauges(i.e. one perpendicular to the other) can be used. Alternatively the gauges can be rotatable to selected degree orientations. Each carriage can have depressible locking type switches, such as cams that allow for an on-depressed position locking the carriages to the elongated body, and an open position allowing for the carriages to be freely moveable.

  • Publication number: 20040133144
    Abstract: Waterproof animal cast and bandage protector for keeping dry and clean an animal's injured limb, which has been covered by a cast or bandage. An elongated tube with two ends, one open end, where the animal's limb is inserted and one closed end. The elongated tube is made of a durable and stretchable covering being smaller in diameter than the cast or bandage, allowing it to conform to the casts or bandages shape. The open end opens via a flexible ring, being smaller in diameter than the cast or bandage. That ring creates a seal and holds tight when cover is unrolled over the animal's cast or bandage. The closed end has a non-skid surface to protect from tearing and to help prevent slipping when the animal is on a potentially slippery surface.
