Abstract: A guard for curb inlets prevents entry of large objects such as cans and bottles into the opening of the curb inlet, but allows water to enter the opening. The guard defines a relief on its bottom side so that the guard may be installed at the correct height without measurement. The guard may be composed of first and second or first, second and third slidably-engaged portions to allow the length of the guard to be user-selectable to fit a variety of curb inlets. The guard may include a grill to strain smaller debris from the water.

Abstract: A colored ring immovably associated with an inlet of an underground tank to enhance the identification of the material in the underground tank. The ring can be bolted to the inlet or engaged with adhesive to the inlet. The ring can be formed as a substantially continuous ring or a plurality of ring members. The ring can be partially positionable in the ground or can be fully disposed above ground. The ring can include a colored surface or can be uniformly colored. The ring can be used in combination with a colored lid such as the color of the lid and the color of the ring are substantially similar.

Abstract: A replaceable mounting ring is disclosed for use with a water closet coupling which is interposed between a water closet drain and a sewer pipe. The mounting ring fits on a channel in a flange near the inlet end of the water closet coupling. The mounting ring comprises two arcuate members, each having a U-shaped cross section formed by a base and a leg on each side of the base, with the base having a lower surface between the two legs. A corresponding end of each arcuate member has an extension from the lower surface of its base of a size which allows the extension to engage the lower surface of the base of the opposite end of the other arcuate member. These extensions enable the ends of the arcuate members to form a mounting ring having a U-shaped cross section.

Abstract: A plastic mounting ring comprises two plastic arcuate members each having a flat upper profile, a flat lower profile and a predetermined thickness. Each plastic arcuate member has a lip extending radially inwardly with an inside diameter that allows it to engage the sides of the channel formed by the flange on the water closet coupling on which it is to be mounted. A corresponding first end of each arcuate member has a notch out of the lower level of its thickness. A second corresponding end of each arcuate member has an extension, coplanar with its flat lower profile, which engages the lower surface of the base of the opposite end of the other arcuate member. The members are fitted together to form a mounting ring having a flat upper profile and a flat lower profile. The mounting ring can be used to replace a flange formation of an installed water closet coupling without removing the total water closet coupling.

These extensions enable the ends of the arcuate members to form a mounting ring having a U-shaped cross section. At least one of these extensions can be fastened to the other arcuate member by a pivot joint which allows that arcuate member to be rotated through an opening in the leg on the outside of the other arcuate member.

Abstract: A vent device connectible in a fill pipe of an underground fuel storage tank having a cylindrical housing with a drop tube and a J-shape tubular fitting with two open ends. The first open end is open within the drop tube and directed toward the underground fuel tank and the second open end is exposed through the wall of the cylindrical housing into an upper portion of the underground fuel storage tank. The tubular fitting has an expansion chamber vertically disposed between the two open ends for holding a float ball therein. The float ball is confined within the expansion chamber by a lower seat of the chamber and a barrier extending across the diameter of the chamber to prevent the float ball from sealing the upper seat of the chamber.

Abstract: A two-stage float actuated shut-off valve for use in underground fuel storage tanks utilizes a drop tube coaxially mounted within the storage tank fill pipe. Fuel flowing into the tank is passed through the drop tube which projects downwardly into the interior of the tank to a valve housing located at the lower end of the drop tube. Floats slidably mounted in a recessed area in the housing outside of the drop tube within the tank independently operate pivoted valve doors to a closed position within the valve housing, a lower float closing one valve door to block a major portion of incoming fuel flow passage when the level of fuel in the storage tank reaches a predetermined first level and a second upper float causing the secondary valve door to overlap an aperture in the main valve door to almost completely close the flow of fuel to the tank.

Abstract: A rotary floor maintenance device having, a motor support base with at least one central aperture, an electric motor having a shaft perpendicular to the motor base through the aperture, and a motor adapter directly coupled to the motor shaft for rotation therewith. The motor adapter has a generally annular flange area and central aperature for receiving the motor shaft. A rotary floor engaging tool has at least one aperture adapted to receive the flange of the motor adapter, to be rotated therewith. The motor support base contains notches along the inner periphery of the central aperture for draining accumulated liquids. Also disclosed is a safety interlock switch to prevent inadvertant operation of the machine.

Abstract: A shooting bench including an upper cross member having legs pivotally attached thereto to allow for collapsing of the legs for carrying of the shooting bench. A brace secures one of the legs in an extended position during use of the bench. The other leg carries a rest member at its upper end which is adjustable for elevation by pivoting the leg about its pivotable attachment to the upper cross member.

Abstract: A vertical axis floor treating machine and support attachment are disclosed. The machine includes a housing to which the attachment is clamped. The attachment includes a frame having a slide thereon. The frame and slide define an aperture for receipt of the housing. Clamps secure the attachment to the housing.

Abstract: An arrangement for dispensing grain, or other like material, characterized by (1) a cushion box communicating with a material passageway, at a material receiving bin, in a ball and socket relationship, including a material outlet and a slot for eliminating trapped material; and, (2) a ball joint, at the upper end of the material passageway, providing versatility in application.

Abstract: The specification discloses a surface cleaning apparatus having a molded plastic housing and an upwardly and rearwardly projecting casing terminating at a handle, the lower portion of the housing including a forward suction nozzle, opening into a recovery chamber. Suction is generated by a blower at the rear of the recovery chamber and a shield positioned in front of the blower prevents liquid from being drawn from the recovery chamber into the blower. A pump removes liquid in the recovery chamber through a hose which empties into a remote drain. A parallel pump tubing causes recycle of liquid through the pump whenever liquid in the recovery chamber is depleted to prevent dry running of the pump. A set of spray nozzles located in the apparatus just behind the suction nozzle is connected through a hose to a faucet which acts as a remote source of clean water. The clean water supply tubing connects to the nozzles through a positive flow additive injector.
