-UNITED STATES WILLIAM N. oosenovn, or FARIBAULT, MISNESOTAL IMPROVEMENT IN DISH-WASHERS.

Specification forming part of LettorsPahnt Neal58s6Q4', dated J auuary 12, 1875; application filed October 1 1874.

To all whom it may concern I v Be it known that I, WILLIAM N. Goscnovn, of Faribault, in the county of Rice and State 'of Minnesota, have invented certain new and useiul Improvements in'Dish-Washers, of

which the following is a specification: t

This invention has for its object to furnish ahighly eflicacious apparatus, whereby dishes and similar articles may be washed with ce- -lerity in a perfect and thorough manner; and

to this end my invention consists. in the comblnation and arrangement of devices hereinafter described and explained.

In order to enable others skilled in the art to make and use my invention, I will proceed -to'describe the particular manner in which I carried it out.

In the accompanying'drawings, Figure 1 is a lon gitudinal sectional .view otia dish-washer" constructed according to my invention Fig. 2 1s a detail sectional view, representing the dish-tank or holder-rack, and relative arrangement of the pump and strainer.

The tank or holder A, which is generally made of a rectangular shape and of metal, is

designed to afl'ord proper facilities for con-..

taining and heating the water which is to be usediin the cleansing operation. In one cornor of the tank there is locateda force-pump, consisting essentially of a stationary cylinder,

'B, a piston, C, and a hollow piston-rod, D, to I the upper end 'of which is attached an inverted cone-shaped, bulb, P, into which the water from the pump flows until it becomes filled,

"when the water seeks an exit through theflexible discharge-hose E. The objectof the bulh P thusintroduced; between the hollow piston-rod D and the-discharge-hose E is to secure a regular and'constant'fiow'of the water .during the operation of washing. It is evident that but for the introductlomefiahe bulb, the action of'the pump would be more or less intermittent. The bulb, however, acts as a-reservoir, from which a, supply of water from the pump is caused to flow with greater regularity. Thus it becomes an essential feature of my invention. The cylinder B possesses the u'su'al'induction-valves.common to pumps, and the piston which operates in the same is packed with vulcanized india-rubber, soas to render theactionof the pump'simple andperfeet. The tubular pisto irrod is connected with dle, G, located in proper respect thereto. Said sleeve, which is made of wood or othersuitatble material, serves as a handle for manipu-' lating the hose' with impunity, for wood'being ing through the hose cannot burn the hand of the person handling the hose.

The dishes to be cleansed or washed are placed upon a rack, H, which is placed in the tance above the water-line. The rack, which,

0 f, fitted securely in a surrounding frame, one

in width, or provided with oii'sets or shoulders d, as shown in Fig. 2, the object of this construction being to enable the rack to fit properly into the tank at the point or corner where the pump isJocated. The double rack is chiefly designed to support dishes inan uplongitudinal andtransverse bars for support 'upper rack is composed of longitudinal bars,

which serve to prevent the dishes from slipping out otplace. The water after having stove, or otherwise, issdischargc'd through the nozzle of the flexible hose in such a manner as to impinge or. act upon the dishes with suflipurities. The water after having acted upon repeatedly used until it is dirt-3', or all the dishes are cleansed.

In order to prevent solid matters, fats, and other impurities floating in the water from same a' wire-gauze screen or strainer, l, which PATENT. OFFICE;

nozzle, a, and with an encircling sleeve or han- I a non-conductor of heat, the hot water passholder or tank, and retained at a proper disproperly termed, comprises two racks or grates, 1

above the other, has one of its sides reduced right or edgewise position, and for this purpose the lower rack or grate e is composed of ing the lower ends of the dishes, while thebeen heated by placing the apparatus .on a

.cient forceto' remove all adhering dirt or im-.

the dishes falls .to the bottom of the tank, from whence it is again drawn up, so as to be passing into the pump, l locate in front of the I is attached to the side walls of the tank. Thisstrainer etfectually prevents the entrance of anything else than water into'the pump; but in order to guard against the entrance of fine sediment, which generally sinks to the bottom, I provide the screen with a narrow imperforate border, J for the objectstated. The great a'lvant-a'ge derived by my invention is that the water can be thrown wherever wanted, and be drawn from the bottom of the tank free from all impurities:

What I claim is A dish-washer, constructed as described,

and consisting essentialiy ofgthe tank A, forcepnmp'provided with the'--balii"orfreservo ir-P,-- the strainer Lihavinglthe solid board J, and the pipe E with its handle G and nozzle a, substantially as herein set forth.

In testimony that I.cl'aim the foregoing I have hereunto set my hand. i
