Abstract: A restrictor plate assembly 10 is disclosed for restricting particulate flow into a curb box 12, through a mouth 14 thereof. The assembly 10 includes a restrictor plate 16 adapted for being secured at an inside surface 18 of the curb box mouth 14. A proximate clamp structure 20 is positioned at a proximate end 22 the restrictor plate 16 and a distal clamp structure 24 is positioned at a distal end 26 of the restrictor plate 16 that is width-wise spaced from the proximate end 26 of the restrictor plate. The proximate and distal clamp structures 20, 24 are adapted for securing the restrictor plate 16 within the curb box 12 without gripping the inside surface 18 or an outside surface 28 of the curb box mouth 14.

Abstract: A clamp includes a base section, from which a pair of sidewalls and prongs extend, where the prongs are designed to grip gussets within the curb inlet and maintain proper alignment with designated portions of the restrictor plate despite manufacturing variations in gussets positioning within the curb inlet. The clamp is capable of securely positioning a floatable restrictor plate within or flush with an opening of the curb inlet so as to prevent floatables from entering storm sewer systems through the curb inlet.

Abstract: Aspects of the present disclosure are directed to a dock protector apparatus. The apparatus includes an elongated pipe and a flange. A floating dock includes at least one floating dock section coupled to mooring pipes secured to a river or lake bed. The mooring pipes are slidably coupled and to the dock section by pipe sleeve assemblies that enable the dock section to slide vertically along the mooring posts. A dock protector apparatus is inserted within an interior cavity of each mooring pipe. Under tidal surge conditions, the decking may reach a vertical position above a top end of the mooring posts. In order to present the deck section from becoming decoupled from the mooring posts, the dock protector apparatus extends upwardly and remains coupled to both the mooring posts and the dock section, thereby maintaining an essentially laterally-rigid mooring between the dock section and the mooring post.

Abstract: A restrictor plate assembly is disclosed. The assembly is adapted for being positioned within a catch basin throat so that the throat extends rearward of the assembly. The assembly has a longitudinally extending restrictor plate and a restrictor plate securing system, which includes a first clamp arm, pivotally positioned against the restrictor plate, for engaging a first throat surface of the catch basin; a second clamp arm pivotally positioned against the restrictor plate, for engaging a second throat surface of the catch basin, the second throat surface opposing the first throat surface; and an urging member which simultaneously urges the first and second clamp arms against the first and second throat surfaces, respectively.

Abstract: A barrier for preventing wildlife from entering a roadway is disclosed. The barrier includes a plate having a bottom edge adapted for piercing a ground surface, and at least one opening in the plate for connecting a corresponding at least one post to the ground so as to provide additional vertical support for the plate.

Abstract: A guardrail screen assembly connectable to a guardrail assembly is disclosed. The screen assembly includes at least one top rail member, guardrail attachment members for attaching opposing ends of the at least one top rail member to opposing guardrail posts, a bottom rail member, and a screen member, attached to the at least one top rail member and the bottom rail member, for preventing debris and animals from traveling to and from a roadway side of the guardrail assembly.

Abstract: A catch basin curb inlet opening cover is a steel plate member which includes a main segment having at least one first opening whereby fluid may pass through said at least one first opening into the curb inlet opening when said plate member is positioned in its intended place, and a bend portion. The bend portion is formed from the main segment by deforming a respective section of the main segment. When in place across the curb inlet opening, the bend portion extends into the curb inlet opening. A respective surface of the bend portion is in sufficiently close proximity to either or both of the left edge or the right edge of the curb inlet opening so that the plate member will resist horizontal movement occasioned by being struck by a snow plow or other heavy duty street equipment. Adjusting means are described which adjust the length of the bend portion to accommodate different inlet openings. The main segment includes a further opening adapted to permit the viewing of a precautionary badge.

Abstract: A security slug punch tool is disclosed. A typical application includes protecting curb box cover assemblies employed on catch basins along thoroughfares. The hand held tool houses a first cylinder extending beyond one end of the tool affixed to a smaller diameter cylinder drive pin. A deformable slug is secured within an elastomeric grommet at one end of the tool. An operator forcibly striking the first cylinder causes the slug to be wedged into a face opening in a bolt head, as, for example, a hexagonal opening in a bolt securing a curb box cover assembly, thereby rendering the bolt tamper proof. The punch tool and slug can be configured for securing a variety of bolts with different face openings.

Abstract: A curb box cover assembly includes a covering member having a plurality of first openings for the passage of street water. Also, second opening(s) are provided on the covering member which cooperate with a clamping device to secure the covering member to the catch basin. The clamping device includes one clamp member which includes a first and second contact member connected by a transition member of prescribed thickness. The clamp member rotationally mounts on a pivot member. The pivot member includes a threaded opening to receive a bolt member which is advanced into the threaded opening by an operator's action. The pivot member rotates in response to the operator's action so that the clamp member rotates from a first position to a second position at which the clamp member secures the covering member to the catch basin opening. The contact members can rotate independently of each other to accommodate irregularities in the interior surface of the catch basin.
