Abstract

Abstract The waste oil collector has a catch pan supported in a cantilever manner by a pair of legs. Apertures are provided in an end wall of the catch pan to which bottles for collecting the drained oil are connected. The bottles extend outwardly at an incline and serve as a counterbalance for supporting the catch pan in the cantilever manner from the legs.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 235 words
A waste oil collector adapted to be placed under the oil pan of a vehicle to catch used oil drained form the engine characterized in that the waste oil is directed into at least one bottle for collection and disposal, said collector comprising a catch pan that is generally rectangular in shape adapted to be placed under the oil pan of an engine for collecting oil that is drained form the engine, said catch pan comprising end, side and bottom walls defining an initial oil collection chamber therein, said bottom wall being inclined to the horizontal so that the oil flows to one end of the pan, said end wall at said one end of said pan having at least one aperture, at least one bottle for receiving and collecting waste oil for disposal extending outwardly at an incline to the horizontal from said aperture, releasable engagement means operatively associated with the aperture in the end wall for connecting the outwardly extending bottle to said end wall to receive waste oil exiting through said aperture, and leg means extending downwardly from said catch pan adjacent said end wall for supporting said catch pan in a cantilever manner and at a sufficient elevation that the oil can drain into the inclined bottle, said bottle in the inclined position thereof serving as a counterbalance for supporting said catch pan in said cantilever manner from said leg means.
Claim 2
Dependent Claim 235 words
A waste oil collector adapted to be placed under the oil pan of a vehicle to catch used oil drained form the engine characterized in that the waste oil is directed into at least one bottle for collection and disposal, said collector comprising a catch pan that is generally rectangular in shape adapted to be placed under the oil pan of an engine for collecting oil that is drained form the engine, said catch pan comprising end, side and bottom walls defining an initial oil collection chamber therein, said bottom wall being inclined to the horizontal so that the oil flows to one end of the pan, said end wall at said one end of said pan having at least one aperture, at least one bottle for receiving and collecting waste oil for disposal extending outwardly at an incline to the horizontal from said aperture, releasable engagement means operatively associated with the aperture in the end wall for connecting the outwardly extending bottle to said end wall to receive waste oil exiting through said aperture, and leg means extending downwardly from said catch pan adjacent said end wall for supporting said catch pan in a cantilever manner and at a sufficient elevation that the oil can drain into the inclined bottle, said bottle in the inclined position thereof serving as a counterbalance for supporting said catch pan in said cantilever manner from said leg means.
Claim 3
Dependent Claim 17 words
A waste oil collector according to claim 1 wherein said bottle is a used soft drink bottle.
Claim 4
Dependent Claim 36 words
