Abstract
Abstract Disclosed is a spill pan which is ideally suited for installation between the rails of a rail siding used for loading and unloading liquid chemicals and solvents. The spill catch pan is designed to catch any inadvertent liquids which are discharged during the loading or unloading process. Such spill catch pan comprises a pair of substantially-planar, rigid segments which are pivotally hinged together at one side of each segment. The first segment also is pivotally mounted at the side opposite its said one side while the second segment is spring-biasedly mounted at the side opposite its said one side. The segments contain a hole penetrating therethrough which is located where the segments are pivotally hinged together. A pair of side walls are mounted adjacent said segments transverse to the hinges. The segments are mounted over a spill retainer at the first segment side opposite pivotal mount and at said second segment spring-biased mount such that said pair of segments are non-planar.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
121 words
A spill catch pan which comprises: a pair of substantially-planar, rigid segments which are pivotally hinged together at one side of each segment, the first segment being pivotally mounted to a first frame at the side opposite its said one side, the second segment being spring-biasedly mounted to a second frame at the side opposite its said one side, said segments containing a hole penetrating therethrough which is located where said segments are pivotally hinged together, a pair of side walls which are mounted adjacent said segments transverse to said one sides and said opposite sides of said segments, said segments being mounted over a spill retainer and being mounted to said frames such that said pair of segments are non-planar.
Claim 2
Dependent Claim
121 words
A spill catch pan which comprises: a pair of substantially-planar, rigid segments which are pivotally hinged together at one side of each segment, the first segment being pivotally mounted to a first frame at the side opposite its said one side, the second segment being spring-biasedly mounted to a second frame at the side opposite its said one side, said segments containing a hole penetrating therethrough which is located where said segments are pivotally hinged together, a pair of side walls which are mounted adjacent said segments transverse to said one sides and said opposite sides of said segments, said segments being mounted over a spill retainer and being mounted to said frames such that said pair of segments are non-planar.
Claim 3
Dependent Claim
15 words
The spill catch pan of claim 1 wherein said rigid segments are rectangular in shape.
Claim 4
Dependent Claim
22 words
The spill catch pan of claim 1 wherein at least one of said segments contains a handle affixed to its upper surface.
Claim 5
Dependent Claim
32 words
The spill catch pan of claim 1 wherein said pivotal hinge for said pair of rigid segments is a continuous hinge which runs the length of said one side of each segment.
Claim 6
Dependent Claim
29 words
The spill catch pan of claim 1 wherein said pivotal mounting for said first frame is a continuous hinge which runs the length of said first frame opposite side.
Claim 7
Dependent Claim
38 words
The spill catch pan of claim 1 wherein said first frame and said second frame each comprise a vertical wall which is connected to a pair of straps which straps are adapted to be mounted to railroad ties.
Claim 8
Dependent Claim

The spill catch pan of claim 1 which is constructed from metal.
Claim 9
Dependent Claim
25 words
The spill catch pan of claim 1 wherein said first frame and said second frame each are mounted to railroad ties located between railroad tracks.
Claim 10
Dependent Claim
43 words
The spill catch pan of claim 1 wherein said segments are mounted such that they form an inverted V when said spill catch pan is in its storage position and form a V when said spill catch pan is in its use position.
Claim 11
Independent Claim
223 words
A method for catching spills which comprises: placing a spill source over a spill catch pan, said spill catch pan comprising a pair of substantially-planar, rigid segments which are pivotally hinged together at one side of each segment, the first segment being pivotally mounted to a first frame at the side opposite its said one side, the second segment being spring-biasedly mounted to a second frame at the side opposite its said one side, said segments containing a hole penetrating therethrough which is located where said segments are pivotally hinged together, a pair of side walls which are mounted adjacent said segments transverse to said one sides and said opposite sides of said segments, said segments being mounted over a spill retainer and being mounted to said frames such that said pair of segments form an inverted V when said spill catch pan is in its storage position and form a V when said spill catch pan is in its use position; displacing said segments where they are pivotally hinged together so that said spill catch pan is moved from its storage position to its use position; actuating said spill source; and at the termination of said spill source actuating, displacing said segments where they are pivotally hinged together to move said spill catch pan from its use position to its storage position.
Claim 12
Independent Claim
223 words
