  • Patent number: 6712089
    Abstract: A recessed, frostproof water faucet having a tubular stem connected to a pivot plumbing unit connected to a subsurface water line through the rear wall of a box-like recess unit. A slider connector connects the water faucet tubular stem and the access panel or lid of the recess unit. The lid pivots on hinges and as one lifts the lid, the faucet is lifted by the slider connector from a horizontal storage position to a vertical locked position for use, the slider connector being connected to a faucet flange and sliding along grooves in tracks mounted along the inner side of the lid. A sliding hinge locks the lid upright, sliding downward along the upper end of the rear wall. The faucet is returned to the storage position by pulling upward and lowering to the closed position, the slider connector sliding forward along the grooves to the stored position.

  • Patent number: 6622960
    Abstract: The present invention is directed to a device and method for preventing hoses, cords and cables from becoming jammed under wheels without impairing productivity nor leading to back strain. The device is comprised of a “U” shaped wedge body with a thin end and a thick end connected by equal top and bottom surfaces and a flat edge that wraps around the “U” shape to be wedged between the supporting surface and the tire tread. The outer expanding edge provides a contact surface for a hose or cable to be guided around the corner of the wheel. The top and bottom surfaces being equal making the device symmetrical and allowing the device to be equally effective when inserted either side up. The body provides a device that can be traversed, not removed, while the wheeled vehicle is being removed from the service area.

  • Patent number: 6216725
    Abstract: A cover for preventing misoperation is easily and certainly attached/detached to/from an operating piece for manual operation provided for a fluid pressure control device. It is attached so as not to be lost even when the cover is detached for manual operation. For this purpose, retaining grooves 7a and 7b are formed on the outer face of a plunger-type operating piece 3 provided on the top face of the body 4 so as to be projected. A cylindrical cover 5 is provided with a hook 10 which is resiliently retained by the retaining groove 7a or 7b and a string-shaped connecting member 12 which is connected to the operating piece 3, thereby preventing the cover 5 from being lost. The height of the cover 5 is set to be equal to or higher than that of the operating piece 3 in a non-operating position.

  • Patent number: 6209749
    Abstract: A lower portion of a shell is slidable along the length of the body of a gas cylinder, the upper portion of the shell is larger than the lower portion and includes a wall extending fixedly from the lower portion configured to laterally surround the valve, gauge and regulator on an end of the gas cylinder and is movable with the lower portion so that it can movably extend over the body of the cylinder. In another design, a rigid shield is mounted on a bar so that it extends over a periphery of the valve, gauge and regulator group that is mounted on an end of the gas cylinder to protect the group against damage by a foreign object when the cylinder is pressed into spaced apart brackets on the bar that prevent rotation of the cylinder around the bar, by a belt around the cylinder and bar. At least one of the brackets is configured to receive a second cylinder.

  • Patent number: 6206030
    Abstract: A thermal insulating bag, with a waterproof outside surface and a heat-reflecting inside surface, is installed, open end downward, over a backflow prevention valve and the associated above-ground water pipes, to cover them. The bag has ballast contained in a hem around the perimeter of the open end, enabling the open end of the bag to conform to and seal against an irregular ground surface. The bag is flexible and can be rolled up or folded flat or in any desired configuration for storage. The ballast material, being heavy, holds the bag down on the ground and, being fluid-like, enables the perimeter of the open end to engage the contour of the ground throughout the perimeter to provide an effective cover-to-ground seal. Tabs extend outward at the open end and have holes in them to enable installation of anchor stakes, to anchor the lower end of the bag to the ground, desired. One embodiment electrically heated.

  • Patent number: 6206033
    Abstract: A valve safety lockout device and a method for using such device to tamper-proof a control valve are disclosed. In the device, a hollow toroidal-shaped body that is divided into two equal halves circumferentially forms the body for the lockout device. A plastic molded-in hinge connects the two equal halves at one end, and a male latch member and a female latch member are each formed at an opposite end of the two halves such that once they are engaged together, the two halves cannot be detached without destroying the latch members and thus making it visible to an operator. The plastic hollow body of the lockout device can be suitably molded of a plastic material of high rigidity including a molded-in plastic hinge connecting the two halves together. The rigidity of the plastic material should be such that the lockout device cannot be compressed or squeezed in order to turn the control valve handle.

  • Patent number: 6199580
    Abstract: A manifold box adapted to contain manifolds for valves controlling the flow of potentially hazardous liquids. This is a rotationally cast sealed plastic box enclosing the valves to contain any leaks from the valves and allow any leaking liquid to drain from the box through a drain tube at the bottom of the box to prevent the liquid from leaking onto surfaces below or adjacent to the valves. Attachment engaging “tee-nuts” are cast in place within the walls of the box and fittings for tubing connections are attached to the walls of the box at openings in the walls. The box has a front access opening sealingly closed by a hinged plastic cover panel. In one embodiment the box is rectangular and is designed with two adjacent sloping walls which permit drainage of liquid from the box into a drain tube regardless of whether the box is mounted vertically or horizontally. In another embodiment the box is square and has one sloping wall containing a drain connected to a drain pipe.

  • Patent number: 6176255
    Abstract: A theft resistant valve cap including a liner adapted for threaded engagement with a standard pneumatic tire stem valve, a sleeve rotatably mounted with the liner to shroud it and an interlocking feature to selectively prevent axial displacement between the liner and the sleeve. The liner includes a hollow body with first and second opposed ends that features shoulders positioned proximate to one of said opposed ends. The shoulders, when employed with the sleeve rotatably mounted with the liner to shroud it, facilitates restricting removal of the cap from the valve stem to authorized individuals, only. Specifically, an interlocking mechanism extends between the liner and the sleeve and limits axial movement therebetween, while allowing rotational movement. To remove the cap from the valve stem, a key is employed which forms an interference fit with the shoulders in the liner, once exposed.
