Abstract

A skimmer cover for a secondary dispersement system orifice in a storm water catch basin prevents inflow of floatable materials, and especially hydrocarbons from motor vehicles, from entering the orifice. The orifice is defined in a neck extending spacedly above the bottom of the catch basin surface to carry the skimmer cover. The skimmer cover provides a top with a peripheral skirt diametrically larger than the neck and supported on the neck to depend therebelow to a point spacedly above the catch basin bottom surrounding the neck. An internal cylinder depends from the cover top within the skimmer cover skirt and defines plural spaced orifices to allow fluid passage therethrough and into the orifice defined by the neck. A depending fastening structure having opposed pivotal lever arms moved by a medial screw therebetween is carried by the skimmer cover top to allow releasable fastening of the skimmer cover within the neck orifice for positional establishment and maintenance of the skimmer cover thereon.

Claims

1. A cover to keep floatable material from entering a drainage system having an input orifice, comprising in combination:

a skimmer cover having a top interconnecting a peripheral skirt, with cross supports carried by the peripheral skirt to support the skimmer cover on the drainage system input orifice with the peripheral skirt depending below the input orifice; and

fastening structure, carried by the skimmer cover to depend into the input orifice, having

a fastening rod with a head carried above the skimmer cover top and a threaded body depending rotatably through a hole defined in the skimmer cover top and spacedly below the input orifice,

a lower pivot plate threadedly carried on a lower portion of the threaded body of the fastening rod,

at least two similar upwardly angled lower fastening arms pivotally carried by the lower pivot plate to extend outwardly therefrom,

an upper pivot plate rotatably carried and positionally maintained on the threaded body of the fastening rod spacedly above the lower pivot plate, and

two similar upper fastening arms, each pivotally depending from the upper fastening plate in coplanar relationship with each lower fastening arm, to to pivotally interconnect with the coplanar lower fastening arm to cause that fastening arm to pivot angularly responsive to rotation of the fastening rod.

2. In a secondary drainage system in a catch basin, having a tubular neck extending spacedly upwardly from the bottom surface of the catch basin to define an input orifice, a cover to keep floatable material from entering the input orifice, comprising in combination:

a cylindrical skimmer cover, having a top defining a medial hole to rotatably carry a fastening rod and structurally interconnecting a depending peripheral skirt carrying cross supports to support the skimmer cover on the neck with the skirt extending spacedly about the neck and below the input orifice defined by the neck to a level spacedly above the bottom surface of the catch basin; and

fastening structure carried by the skimmer cover having

a fastening rod with a head carried above the the cover top and a threaded body depending through through the medial hole defined in the top and extending spacedly below the input orifice defined by the neck,

a lower pivot plate threadedly engaged on a lower portion of the fastening rod and pivotally carrying two angularly upwardly extending, substantially coplanar lower fastening arms having a length to contact the inner surface of the neck of the secondary drainage system, and

an upper pivot plate rotatably carried and positionally maintained on the fastening rod above the lower pivot plate, said upper pivot plate pivotally carrying two substantially coplanar upper fastening arms to angularly depend therefrom and pivotally interconnect with the medial portion of the lower fastening arms to cause the lower fastening arms to pivotally move responsive to rotation of the fastening rod.

3. The cover of claim 2 wherein the top member is of a surface of revolution with a dome configuration.

4. The cover of claim 2, having an input baffle of similar cross-sectional shape to the skirt, carried within the periphery of the cover and between the cross supports and the top of the skimmer cover, said input baffle defining a plurality of circumferentially spaced orifices to allow fluid to pass therethrough and into the input orifice defined by the neck.
