Abstract
Abstract A drain pan for radiators and cooling systems includes a base panel which is molded or otherwise formed into a coffer shape defined by upstanding sidewalls extending continuously about the perimeter of the base panel. The base panel includes upwardly extending shoulders raised slightly above the base panel to support a grid formed of a plurality of upwardly extending panels. The shoulders define an X pattern on the base panel in addition to shoulder portions spaced inwardly of the sidewalls and extending parallel thereto. The upstanding panels are equally spaced and oriented parallel to perpendicular axes to form a rectilinear matrix. The base panel includes concave recesses at the corners of the coffer to accommodate wheels or rollers affixed thereto.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
A drain receptacle for receiving effluent from a vehicle, comprising a pan having a base panel, a plurality of sidewalls extending upwardly from the perimeter of said base panel and formed integrally therewith, said side walls extending continuously about said base panel and defining therewith an upwardly opening coffer, said base panel including shoulder portions extending upwardly into said coffer and disposed in longitudinal fashion along said side wall, lattice means disposed in said coffer for attenuating and arresting wave motion in and spattering from liquid contained in said coffer, said lattice means impinging on and supported by said shoulder portions, wherein said base panel includes a plurality of corners, and a plurality of upwardly extending concave wall members, each disposed at one of said corners and extending between the sidewalls converging thereat.
Claim 2
Dependent Claim
133 words
A drain receptacle for receiving effluent from a vehicle, comprising a pan having a base panel, a plurality of sidewalls extending upwardly from the perimeter of said base panel and formed integrally therewith, said side walls extending continuously about said base panel and defining therewith an upwardly opening coffer, said base panel including shoulder portions extending upwardly into said coffer and disposed in longitudinal fashion along said side wall, lattice means disposed in said coffer for attenuating and arresting wave motion in and spattering from liquid contained in said coffer, said lattice means impinging on and supported by said shoulder portions, wherein said base panel includes a plurality of corners, and a plurality of upwardly extending concave wall members, each disposed at one of said corners and extending between the sidewalls converging thereat.
Claim 3
Dependent Claim
35 words
The drain receptacle of claim 1, wherein said lattice means includes a plurality of upwardly extending panels disposed in spaced apart, intersecting fashion, said upwardly extending panels being substantially equal in height to said sidewalls.
Claim 4
Dependent Claim
24 words
The drain receptacle of claim 1 further including a plurality of wheeled assemblies each secured in subjacently depending fashion from one of said corners.
Claim 5
Dependent Claim
17 words
The drain receptacle of claim 1, wherein said base panel includes a resealable drain port extending therethrough.
Claim 6
Dependent Claim
23 words

Claim 9
Dependent Claim
40 words
The drain receptacle of claim 7, wherein said shoulder portions are raised slightly with respect to said base panel to define a narrow, laterally extending open flow space between said base panel and the lower edge of said lattice means.
Claim 10
Dependent Claim
27 words
The drain receptacle of claim 1, wherein each of said sidewalls includes a lip at the upper distal portion thereof, said lip extending outwardly from said sidewall.
Claim 11
Dependent Claim
