3 Claims. (Cl. 134-99) This invention relates to washing and cleaning ap- 2,897,830 Patented Aug. 4, 1959 positioned in the upper end of the container, a spray nozzle 14 supplied with air by an air pressure connection 15 and connected to an air lift casing or head 16 through a valve 17, and a spray hose 18 through which a cleaning 5 fluid or the like may be flushed or sprayed over the paratus of the type used for cleaning greasy and dirty parts removed from automobiles and other machines, and in particular a tray in which a solvent for loosening hard grease, oils and the like from parts of machinery is positioned and which after use is recovered for reuse and wherein the cleaning fluid or solvent is elevated by an air lift and sprayed over the parts with air under pressure.

The purpose of this invention is to provide a parts washer and cleaner in which the parts are thoroughly cleaned and washed with a solvent elevated and sprayed with an air lift.

Various types of apparatus have been provided for removing the hard grease, oils, and dirt from machine parts, however, as it is necessary to subject the parts to a solvent in cleaning the parts have been placed in one container with a solvent therein and then removed for cleaning. By this means it is necessary to handle the parts several times and in numerous instances some of the parts are misplaced. With this thought in mind this invention contemplates a parts washer wherein a solvent in which the parts are first positioned may be drained through a filter into a container, and recovered by an air lift by which the solvent or other liquid is flushed or sprayed over the parts.

The object of this invention is, therefore, to provide an air lift by which a solvent or other cleaning fluid may be drawn upwardly and flushed or sprayed over machine parts for cleaning the parts.

Another object of the invention is to provide a parts washer and cleaner in which the parts may be thoroughly cleaned and washed by a single operator.

A further object of the invention is to provide a combination parts cleaner and washer in which the device is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a tray or sink having a drain therein with a filter compartment below the tray and a container upon which the tray and filtering element are positioned, and means for spraying cleaning fluid over parts in the tray.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Figure 1 is a side elevational view illustrating the relative positions of the parts of the improved parts washer and cleaner.

Figure 2 is a front elevation of the improved parts washer and cleaner.

Figure 3 is a sectional plan taken on line 33 of Fig. 2 showing the tray with the drain connection at the center thereof.

Referring now to the drawings wherein like reference characters denote corresponding parts the improved parts cleaner and washer of this invention includes a tray or sink 10, having a drain 11 in the intermediate part, a container or drum 12 upon which the tray is positioned, a filter compartment 13 depending from the tray and parts and by means of which a solvent may be supplied to the tray from the lower part of the container 12 through a pipe or tube 19.

The safety parts cleaner and washer is operated by an air lift formed with a housing 16 in which the pipe 19 extends downwardly to the lower end of the container 12 with an air pressure tube 20 extended from thevalve 17 through the pipe 19 to a point 21 spaced fromthe lower end of the pipe and with the upper part of the container provided with a vent formed by a pipe 22 which extends from a point 23 upwardly to a point 24 in the casing 16.

With air under pressure supplied through the tube 15 the valve 17 is opened whereby the air is discharged at the point 21 driving the solvent upwardly through the pipe 19 and into the casing 16 from which the solvent is discharged through the hose 18 over parts in the tray 10. The pipe 22 provides a vent through which air in the upper part of the container 12 escapes.

An air blast for drying and cleaning is supplied through the nozzle 14 on the end of the tube 25 which extends from a fitting 26, one end of which is connected to the supply tube 15. The fitting 26 is also provided with a branch connection which is connected to the valve 17 with a close nipple 27.

Although it is preferred to use a conventional oil drum, which is found at substantially all filling stations and the like, for the container 12 it will be understood that a barrel, can, or other suitable container may be used.

In assembling the parts the tray with the filter 13 depending therefrom is positioned upon the upper end of the container 12 with the tubes or

pipes

19 and 22 inserted through openings 28 and 29, respectively, in a shelf 30 extended from the rear wall 31 of the tray 10 and with parts positioned in the tray solvent from the lower end of the container 12 is discharged over the parts through the hose connection 18 with the air lift elevating the solvent to the casing 16.

After use the solvent drains through the drain connection 11, passing through the filter, and back to the lower end of the container 12.

A circular plate 32 is hinged to the lower end of the filter element for retaining waste filtered material until the tray and filter are removed for cleaning.

It will be understood that modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

1. In an air lift for a parts cleaner and washer, the combination which comprises a container, a tray having a filter depending therefrom positioned on the container with the filter extended into the upper end of the container, a pipe extended from the lower part of the container upwardly to a point spaced above the tray, an air lift casing positioned on the upper end of the pipe, a spray connection extended from the air lift casing, a tube extended through the air lift casing and downwardly through the pipe to a point spaced upwardly from the lower end thereof, a vent extended from the upper part of the container to the air lift casing, a valve to which the upper end of the tube is connected, an air pressure connection extended from the valve, and a nozzle connected by a tube to said air pressure connection.

2. A tool and parts washer comprising a drum positioned with the axis vertically disposed, an open tool and parts retaining tray positioned on the drum, a filter carried by and depending from the tray, a pipe positioned at one side of the tray and extended into the drum, a head on the upper end of the pipe, a vent extended from the upper part of the drum to the upper part ofthe head, a pressure tube extended from the point spaced above the lower end of the drum upwardly through the pipe and head, a fitting on the upper end of the tube, a valve in said tube, an air pressure supply tube extended from the fitting, and a spray hose extended from the lower part of the head for spraying fluid from the drum over tools and parts in the tray.

3. A tool and parts washer comprising a drum positioned with the axis thereof vertically disposed, an open tool and parts retaining tray positioned on the drum, a filter carried by and depending from the tray for filtering material passing from the tray to the drum, a pipe positioned at one side of the tray and extended into the drum, a head on the upper end of the pipe, a vent positioned at one side of the pipe and extended from the upper part of the drum to the upper part of the head, a pressure tube extended from a point spaced above the lower end of the drum upwardly through the pipe and head, a T- fitting on the upper end of the pressure tube, a valve in in the pressure tube positioned betwen the head and fitting, an air pressure supply connection extended from one side of the T-fitting, a hose having an air nozzle on the extended end secured to another side of the T-fitting and positioned to discharge air over tools and parts in the tray, and a spray hose extended from the lower part of the head for spraying fluid from the drum over tools and parts in the tray.
