SPECIFICATION forming part of Letters Patent No. 631,960, dated August 29, 1899.

Application filed January 26, 1898. Serial No. 667,953. (No model.)

To all whom, it may concern.-

Be it known that I, DANIEL W. HAWKES, a citizen of the United States of America, residing at Deering, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Dish- Oleaners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in dish-cleaners,and more especially to that class of cleaners in which a pump with asprayingnozzle is mounted in a suitable tank. Its object is to secure a more rapid and perfect cleansing of the dishes with the least possible quantity of water.

In the drawings herewith accompanying and making a part of this application, Figure l is a vertical section taken on a diagonal line through a rectangular tank, the pump occupying one corner of the tank and the delivcry-pipe a position at or near the center thereof. Fig. 2 is a vertical sectional view of the sprayer-nozzle. Fig. 3 is a detail plan view of a portion of the cover, showing the sliding portion surrounding the pump-handle. Fig. 4 is a transverse vertical sectional view of the tray, showing arrangement of the dish-supporting bars.

Similar letters of reference refer to like parts.

In said drawings, Arepresents a suitable tank, in which is mounted a pump consisting of a suitable barrel B, piston O, valve D, and delivery-pipe consisting of a horizontal section E and a vertical section F, said horizontal section lying on or near the bottom of the tank, the inner end G being bent downwardly from the outlet-opening in the pump-' barrel, as seen at H. In the horizontal delivery-spout is a swinging valve 1,. which tends to prevent the water in the horizontal section of the pipe from being drawn back when the piston is lifted, thus keeping the vertical section of the pipe constantly filled and likewise obviating the necessity of entirely submerging the horizontal pipe, it only being necessary to submerge the inlet to the pump-barrel.

On the end of the vertical section is secured my improved sprayer, which consists of two or more disks arranged one above the other at some distance apart. The diameter of the openings in said disks gradually decreases from the lower to the upper. This construction is illustrated in Fig. 1 and 2, J representing the upper or solid disk, K an intermediate disk with a central opening, and L and M the lower disk with opening 0, said openings being concentric with the deliveryspout. The disks may be curved, as seen at P in Fig. 1, or horizontal, as seen atQin Fig. 2. The disks are supported on the vertical section of the delivery-spout inany convenient manner-as, for example, by rods R, secured to a vertical ring S, adapted to he slid down over the end of said section, the successive disks being supported each on the disk below bysmall rods or posts T. In order to secure the delivery of the water from the sprayers in every radial direction, the supporting-posts should be so arranged that no two shall be in the same vertical line,whereby the space obstructed by the post supporting one disk would be free and open on one of the other disks.

The tray forholding the dishes to be washed has a recess X, which extends around the pump-barrel, and a perforated bottom W. The tray is mounted on suitable supports Y, secured to the tank, and may have on the interior two series of transverse bars Z,arranged one above the other, the lower ones being nearer the center than the corresponding upper ones, as seen in Fig. 4, so that the dishes when set therein will have an inclined position and be held securely thereby during the operation of washing, so as to present the dirty surfaces of the dishes to a more direct action of the spray.

To avoid the spattering of water upon the operator, it is necessary that the washing be done with the tank covered. It is consequently necessary for the handle of the pump to extend upwardly through the cover. It would be inconvenient to remove the pumphandle every time it was necessary to remove the cover, which would be necessary if the cover were entire. To obviate this objection and at the same time prevent the spattering of the water, I make a reentrant cut a in the cover, and over this cut and pivotally secu red to the cover I place a swinging slide I), having a portion 0 cut out, through which the pump-handle passes, and for convenience I secure to the sliding section a knob 61 and to the adjacent edge of the cover a clasp 6, underwhich the edge of the slide passes and by which it is held when the slide is closed.

The operation of the spraying-nozzle will be apparent. As the nozzle-head is filled a portion only of the water is intercepted by the lower disk and is thrown out radially in all directions. A portion of the water which passes through the lower disk strikes upon the intermediate disk and is thrown out radially in all directions but at a dilferent elevation. The remaining portion of the water strikes upon the upper disk and is thrown out radially in all directions. It will be evident that the shape of the disks and their angles of inclination may be varied indefinitely. Some of the disks may be horizontal, some curved, and some inclined downwardly in the same nozzle, if desired.

Having thus described my invention and its use, I claim 1. In a dish-cleaner, in combination, a suitable tank and a pump mounted therein having a delivery-spout anda nozzle consisting of two or more disks superimposed, all the disks excepting the upper one having openings therein concentric with the vertical sec tion of the delivery-spout, substantially as and for the purposes set forth.

2. Inadish-cleaner, in combination, a suitable tank, a pump mounted therein, a delivery-spout, a spraying-nozzle mounted on the end of said delivery-spout and consisting of a series of disks superimposed and openings in all of said disks excepting the upper one concentric with the opening in the deliveryspout, the diameter of said openings decreasin g from the lower to the upper, substantially as and for the purposes set forth.

3. In a dish-cleaner, in combination, a suitable tank, apump mounted therein having a suitable delivery-spout, a cover to said tank having a portion removed at a point over the pum p-barrel and a supplementary cover pivotally secured to the main cover and adapted to slide over said open space, substantially as and for the purposesset forth.

4. In a dish-cleaner, in combination, a suit able tank, a pump mounted therein and provided with a suitable delivery-spout, a cover having a section cut away at a point over the pump, a sliding sect-ion pivotally secured to one edge of the cover and adapted to slide over said cut-away portion and means forsecuring said slide in closed position, substantially as and for the'purposes set forth.

In testimony whereof I afiiix my signature, in presence of two witnesses, this th day of January, 1898.

DANIEL W. I-IAWKES.
