  • Patent number: 4052227
    Abstract: A parts washer having a tub, a cylindrical drain in the tub and a cover hinged to the tub so as to cover the tub when the cover is lowered. A novel overcenter linkage is mounted at one end in the sink and at the other end on the cover to hold the cover in a raised position as desired. The linkage has at least one link and preferably multiple links which are fusible at relatively low melting points such that the fusible link or links will melt quickly if a fire occurs in the tub. A solvent receptacle is pivotably mounted beneath the tub and has a drain opening at a side for quickly and easily draining and replacing the solvent used in the system. A splash plate extends above a back wall of the tub and covers the joint between the back wall and the cover to keep splashed solvent from leaking down behind the cover. A cylindrical drain tube depends from the bottom wall of the tub and has an open top into which is placed a compressible open-cell foam material for filtering the solvent which passes therethrough.
