Automotive engine lub-oil drainage and disposal structure

Claim 1

A structure for use in economical draining and disposal of used automotive engine lubricating oil comprising: a unitary used-oil bag stand formed of a length of manually bendable wire having a first outer portion defining a relatively large base for supporting the stand at rest upon a horizontal surface, a second portion defining an upright leg at one end of the wire portion defining the base, a third portion defining a horizontal arm extending inwardly of the upper end of the portion of the wire defining the leg, and a fourth, annular portion defining a throat element having a preselected small diameter of no greater than approximately 5" overlying the center of said base, said throat element being held by said leg and arm in an elevated horizontal position above the base a distance similar to the diameter of said throat element, said throat element having a transverse size substantially smaller than that of the base so as to be disposed substantially within the upright projection of the said base; a used-oil receiving bag having an open end extending upwardly through and turned over said throat element; and clamping means for removably securing said bag open end about the wire portion forming said throat element to provide an unobstructed entrance for free ingress of oil into the bag, said upright leg being of a length substantially less than the length of said bag so that a major portion of the bag may rest upon the underlying surface upon which the stand is placed when said open end is so secured; as when positioned under an engine to receive oil draining therefrom, the bag being secured to the stand at said throat element only, the size of said bag being preselected to assure that the collected oil is supported substantially only by the underlying surface and stand base thereby to avoid placing stress on the wire stand sufficient to cause undesirable deformation thereof in oil-collecting use and whereby the open end of the bag is maintained fixed to said throat element in oil-receiving disposition spaced above the underlying surface while the bag is receiving the entire quantity of used oil from the automotive engine, said bag being formed of a strong, nonpermeable synthetic resin, such as polyethylene, adapted to have the open end gathered and tied to define a substantially leakproof, readily disposable bag of the collected used oil.
