l SANITARY msn-WASHER.

Application led February 9, 1920. Serial No. 357,444.

T 0 all/whom t may concern: y

Be it known that I, HERMAN W. HIGLEY, citizen of the United States, and a resident of Yonkers, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Sanitary Dish-Washers, of which the following is a specification. Y

The object of my inventionis to provide a dish washer employing both a running stream of water and a pliant rubber scraper,

conveniently arranged to work in conjunction with one another, so thatvthe operator or user may employ eitherl the water or scraper, or both. Thev water may be first applied, for the removal of all loose substances, while the scraper may be employed* during the same operation in rubbing and scraping the dried and hard particles, with the flowing water used as an assistant.-

In this combination I provide means convenient to the operator or user for the manipulation of both water and scraper, and both are necessary in thev removaland cleansing of food stuffs from the utensils.

The water alone doesnot provide proper means forremoving the hard and dried particles, such as dried egg, syrups and other hard drying food stuffs, which have. to be subjected to agitation in addition to the water to loosen andremove the same.

In my invention I provide a nozzle attached to a flexible tube, for conveying the water, that will condense the water into ay stream of a thin, uniform width andthickness under pressure. The stream, to cover as large a surface as possible, -isv arranged thin andwide, with means for maintaining the shape or form intoa solid flow of water about one sixty-fourth of an inch in thickness and two inches wide at the nose of the nozzle. The stream gradually increases in width as it leaves the nose. An object is to maintain an even force of the flow across the entire width, without spreading or separating in particles from the main stream, keeping and maintaining the entire width of the stream or flow effective for quick and practical results. `The water is transmitted from the nose of the nozzle in a condensed sheet form, resembling a sheet of glass in appearance, iovving uniformly the entire width and thickness.

In other similar devices of this character trouble is experienced in maintaining a stream of suitable shape in a uniform width and thickness across the entire surface of the stream. means for condensing the water y,in such a manner v that an even and uniform iiow is provided. These condensers are arranged in the nose of the nozzle, shaping the course of the water so that the stream holds together in a fiat sheet within a fixed distance from the nose of the nozzle. In this manner I overcome the disadvantages of'a loose, irregular stream, as discharged from the nose of a nozzle Without the use of condensers. In addition to the stream or water flow as outlined I employ a rubber band attachment, for use as a scraperin removing the remaining substance the water flow does not wash away. Owing to'the elasticity of the rubber it will clean both vsmooth and irregular surfaces with'equal effectiveness, and owing toits pliability may be worked into crevices and uneven surfaces with rapidity, removing all substances from the even and uneven surfaces alike, when.the scraper is used in a rubbingv or scraping movement over the matter to be removed. ADuring the rubbing `and scraping movement the water flow is being applied from thenose of the nozzle, the water softening the substance during the'rubbing operation.

The scraper forms'an important part of my invention, as other devices depending solely upon the water flow, hot orcold, have In my improvement I 'employ l Specification of Letters Patent. Patented 14 1920.

the -v'vater does not possess suiicient dissolv- Ving properties lto remove the hard particles,

and therefore does not wash anything but the loose substance away.

By the addition of the scraper in connection with the water iiow, the scraper being used for removing the hard and dried particles, I overcome the disadvantages of other similar devices, and this together with an improved stream or water flow of a uniform width and thickness, constitute the important features of my invention.

I attain these objects. by means of the mechanism illustrated in the accompanying drawing, in Which,-

Figure 1 is a plan view showing the nozzle attached to the flexible tubing with a sheet 'of water being discharged from the nose.

Fig. 2 is the same view as No. l omitting the water stream and rubber scraper, showing the condensers on both sides.

Fig. 3 is an end view looking directly into the nose of the nozzle.

Fig. 4 is a sectional view at 'af-a Fig. 2. Fig. 5 is a side view showing the thickness ofthe stream of water being discharged. Similar numerals refer to similar parts throughout the several views. f

The nozzle is composed of two parts 1 and 2, which are soldered together at l'the joint or seam 3, as clearly shown in Fig. 5, and correspond in shape and form with each other. The parts 1 and 2 are pressed from thin metal, so that when joined together at the seam Sileave a water chamber 4, YF ig.

4, within Ythe shell, of the shape and form of the outside of thel parts 1 and 2, less the thickness as shown throughout the drawy in s.

he round shank 5 with Vthe securing bands 6, V6b Aand 6c, provide means forattaching and securing the flexible hose for conveying the water to the water chamber The water flow is fedv within the nozzle. from a faucet, through thellexible hose 7 to the opening in the shank 5 vengaged within the hose.v n n Withthe hose connected tothe lfaucet or Vwater supplyfthe water will Vfirst pass the nozzle,l where the opening4,F-ig. 3, or; lthe nose of the nozzle is arranged. The

nose v12V of thelnozzle is made rounding tov assist in regulating the flow of? the stream to the proper thickness,'which according to that arranged is about one sixty-fourth of'V kan inchjthick, although the thickness may be varied to meet necessary requirements.

densers force the water in its flowV into a Y solid mass that holds together after passing from the nose of thenozzle, regulating the stream to a fixed anduniform width.V

The rubber scraper'16 having a narrow flat, scraping surface 17, with beveled edges 18, is arranged to fit snugly and tightly over the wider portion of the nozzle, near the nose 12, where it assumes a convenient position for use in combination with the use of the stream. The'scraper lrmay be adjusted in separate pieces tovboth sides of the body by means of rivetsor otherwise. lhile the scraper is made with a narrow Hat surface 17, and beveled sides, as a more prac.- tical form to be employed, a round, square orother form may be used with satisfactory results. Y V

VHaving thus described` my invention, I claim: Y Y

1. The. combination in a dishwasher of vthe character describedof a nozzle having a water' chamber .Y with a narrow. opening `at its outlet end,v lthe walls ofA the nozzle converging on .the sides and ends of said f chamber to said outlet, and the sides being a water-chamber with a narrow opening at its outletend, the walls of the` nozzle converging on the sides and endsof saidV chamber to said outlet, and the sides beingslig-htly convex at the outlet inthe direction ofthe flow of'water. .n
