Filed Apr. 8, 1966, Ser. No. 541,292 1 Claim. (Cl. 134-111) ABSTRACT OF THE DISCLOSURE A rectangular sheet metal casing supports a removable wash basin having flanges resting upon the upper edges of the casing. A fire protection top cover is hinged to the casing along one side and normally held in raised position by a fusible link subject to release upon overheating as by a fire in the basin. A solvent tank is positioned below the basin with a pump connected to deliver solvent through a nozzle into the basin. An upstanding cylindrical filter with a closed 'bottom is mounted in the tank above the level of the solvent and centered beneath a drain opening in the basin to receive dirty solvent from the basin and filter the same as it flows back into the tank.

This invention relates to parts washers and more particularly to a washer adapted to be used to remove grease and oil from machine parts.

It is an object of this invention to provide a washer for machine parts to cleanse them of oil and grease under a constant stream of cleaning fluid.

Another object is to provide a constant stream of filtered cleaning fluid for use in a parts washer.

Another object is to provide a parts washer in which the danger of fire is minimized.

A further object of the invention is to provide a parts washer in which the danger of marring parts being washed is minimized.

A further object is to provide a parts washer for machine parts in which the washing fluid is maintained free of gritty or abrasive particles.

Other objects will become apparent upon considering the following specification which when taken in conjunction with the accompanying drawings illustrates a preferred form of the invention.

In the drawings:

FIG. 1 is a vertical longitudinal cross-section through the center of the washer showing the construction thereof;

FIG. 2 is a vertical transverse cross-section taken on the line 2--2 of FIG. 1;

FIG. 3 is a transverse horizontal cross-section taken on the line 3-3 of FIG. 1;

FIG. 4 is a front elevational view of the intake to the circulating pump for the washing solvent; and

FIG. 5 is a perspective view of the fire safety release for the washer cover.

Referring to the drawings and particularly to FIG. 2, the washer has a cabinet comprising a bottom piece to which side Walls 1212 are attached, together with front and rear walfs 14-15. The rear wall terminates at its upper end in a horizontal shelf 16 (FIG. 2) which, when taken in conjunction with the front and side walls forms a support for a wash basin 17. The wash basin 17 is supported on the tops of the four upstanding ends of the vertical sides of the cabinet and on the horizontal shelf 16 at the rear of the cabinet.

A cover 20 is secured to the top of the rear panel by a hinge 21. An arm 23 is fixed to the rear of the panel 15 and supports a link chain 24, or the like, which is con- "ice nected to the cover 20 through a heat releasable link, generally designated 25, shown in FIGS. 2 and 5.

The link 25 is composed of two pieces 25 and 25" with each piece having an eye 26 on its outer end. The ends of the pieces 25' and 25" opposite the eyes 26 are secured together by soldering with a low melting point solder. A bracket 27 is fixed on the inner side of the cover by Welding, or the like, and the link 25 is joined at one end thereof by a bolt and nut 28-28 passing through one eye 26, permitting the opposite end of the link to project through an opening 29 in the cover 20 for attachment to the chain 24, to retain the cover in a normally open position.

A solvent tank 30, preferably square, is mounted in the casing 10, 12, 14, 15 and retained centered beneath a drain port 31 in the wash basin 17 by a plurality of angle irons 32 fixed in the bottom 10 of the casing.

A pair of supporting brackets 3333 extend between the opposite corners of the square solvent tank 30 to both center and carry a solvent filter 34 under the drain port 31 in the wash basin 17.

The filter 34 is contained in a cylindrical casing 35 having a multiplicity of apertures therethrough and a continuous zig-zag filter paper 36 (FIG. 3) the inner edges thereof standing vertically on end about the interior surface of the perforated cylinder 35 to form a filter element through which solvent entering the filter 34 from the sink may pass but through which solid impurities may not pass.

A positive displacement rotary fluid pump 37 is mounted within and adjacent the bottom of the tank 30 and has an inlet 38 to receive the filtered cleansing fluid from the filter and deliver it through the flexible steel hose 40 to a nozzle 40' within the sink 17 to reuse on pieces being cleaned.

An electric motor 42 drives the pump through a shaft (not shown) passing through the container wall.

Electircity to drive the pump is provided through an electric cord 44 through a snap switch 45.

OPERATION Before using the washer tank the cleansing fluid is supplied to the bottom of the tank 30 to a height below the bottom of the filter.

When it is desired to wash grease or oil covered machine parts to remove the contaminated matter, the tank 30 is supp ied with a suitable solvent to a height just below the level of the filter support 33. The solvent preferably is one having a high flash point so that it is not readily flammable.

The motor 42 is then started, pumping the solvent through the flexible steel pipe 40 and nozzle 40' enabling the operator to wash all grease and dirt off the parts, the resulting fluid flowing through the drain port 31 and into the center of the filter. The fluid then passes through the filter element 34 which removes metal particles and heavy greases.

It will be realized that the hereinbefore described form of the invention is to be taken merely as a preferred embodiment thereof and that various changes in size, shape and arrangement of parts may be made without departing from the spirit of the invention or the scope of the subjoined claims.

That which is claimed as new and is desired to be secured by US. Letters Patent is:
