The ea-id lid A- further object of the invention is to prois hinged along a top panel [2' at the back wall thereof.

swung inwardly beneath the under surface of lid l2, as is indicated in Fig. 3, and to be be attached thereto temporarily by respective and manually operable latching members l and I 6. The said wing elements are to be maintained in this position during the initial cleansing operation, viz: immersion of the work in a suitable cleansing liquid l1 contained in the tank H, the lid during this period being lowered, for example, by means of the handles l8, to close the tank and its wing portions then assisting in thermally insulating the tank contents by interposing a layer of air.

Provision is made to heat the liquid during this period, for example, by means of a burner 29 discharging into a flue system 2| located along the bottom of the tank and preferably at the rear thereof, the flue system being provided with a discharge stack 22 extending through the top panel l2 of the tank. An air type agitator indicated at 23 serves to stir the cleansing liquid.

Such arrangement, together with the various cleansing liquid supply and drain connections, is well understood in the art and no claim is made thereto. Also, it is desirable to insulate thermally the'tank walls in the usual manner, and it is preferred to locate a baffle plate 2 I in front of the flue system 2|, said baffie being displaced somewhat from the bottom of the tank to enhance circulation of the liquid in said tank in the heating moval of the loosened carbon deposits, oil and other foreign matter.

This is generally effected by spraying the work with hot water, the objections to which have hereinbefore been noted.

In accordance with the invention, the work is not removed from the tank apparatus after the soaking operation, but the portion to be rinsed is merely elevated somewhat above the level of the liquid I'I therein, as is indicated in Fig. 2. The

wing elements 13 and M are then unlatched, the lid l2 having been elevated previously to accomodate the'hoisting of the Work above the liquid; and the said wing elements are swung outwardly to lie substantially in the respective planes of the corresponding side walls 24, 25 of the tank. They are conveniently retained in this position by slipping their lower edges behind lugs 26, 21 extending inwardly from said side walls.

A semi-enclosed space 28, Fig. 2, open only at the front and top is thus afforded by the hood in the manner described, the lid [2 forming a background and the wing elements l3 and I 4 side Walls about the work 29, as is indicated. The said work is thus in a convenient location for the final cleansing operation, the discharge of a cleansingmedium thereon being efiected from the front and ious ways, but it is preferred to conduct this final cleansing of the work in a manner which will not relatively fine, high velocity spray; and. furthermore, use is made of the initial cleansing liquid rather than hot water as has been the practice heretofore. The liquid, of course, will first have the scum, resulting from the immersion operation, removed as by raising the level thereof to an extent to flow off the objectionable scum through a suitable scum gutter 30 provided along a side panel 25, as is well understood. Thereupon, a spray device 3| including a weighted suction pipe 32 extending into the liquid I1 and an atomizing line 33, for example, for compressed air or steam, is operated to direct the spray against the work. The said spray device may be supported conveniently for operation by the top edge of the front wall 34 by suspending it thereover, as by means of the hook 35 of said device.

I claim:

1. The combination with a cleansing tank comprising bottom, front and rear, and side walls to aiford an open container for a cleansing liquid; a lid member for the tank hinged at the rear wall, and end wing members secured to opposite ends of the lid member to fold thereunder, together With manually operable latching elements to attach the wing members to the under face of the lid member when the latter closes the tank and adapted for release 'of the wing members when the lid is in elevated position, said wing members being adapted then to be extended outwardly therefrom substantially into the respective planes of the side walls to provide with the lid member a spray shield; of a spray unit, having mean for removably supporting the same over the upper edge of the front wall of the tank, whereby to cleanse an article elevated o'ut'of the interior of said tank and suspended in the space above the same and within the partial enclosure defined by said shield, which latter confines substantially Within the said space spray from thespray unit directed to said elevated article.

2. The combination claimed in claim 1, wherein the spray unit includes a suction pipe adapted to extend into the tank when said spray unit is supported over the upper edge of the front wall of the tank.
