DISHWASHER 2 Sheets-Sheet 2 THOMAS F. ALLEN.

- Attorneys.

Patented June 9, 1953 UNITED STATES PATENT OFFICE 2 Claims.

This invention is a dishwasher particularly adapted for household use characterized by the absence of moving parts and the absence of power means.

The'dishwasher of this invention is of exceedingly simple construction and includes a unitary dish rack to support plates, cups, saucers, silverware, etc., in proper position, to positively eflect a consummate cleansing action by impinging the surfaces of the articles, carried by the rack, with the soap-charged hot water, the articles being also sprayed from above, through the water supply pipe, for rinsing the articles.

The article carrying rack of this invention is readily removable from the dishwasher container but when in use will not move, even under extreme water pressures, thereby avoiding possibility of cracking or breaking dishes, glasses and the like carried by the rack.

In summation, it is the object of this invention to provide a portable dishwasher which employs only the power incident to the faucet water used for washing and rinsing the articles contained in the washing chamber, the separate washing and rinsing actions being accomplished by a water supply pipe which extends through the top of the washing chamber concentrically into the latter, the pipe being provided with independent series of water spray openings positioned so that one series of openings will permit direct impingement of articles in the base portion of the rack, while another series permits impingement of articles extending above the base and still another series is arranged in a plane above the rack so as to spray the articles from above and thereby obtain a rinsing action of all of the articles supported by the rack.

Other objects of the invention will be apparent from the following description of the present preferred form of the invention, taken in connection with the accompanying drawings, wherein:

Figure 1 is a perspective view of a dishwashing machine constructed in accordance with the present invention, showing the lid and water supply pipe carried thereby, arranged in spaced relation above the top of the container;

Figure 2 is a vertical sectional view of a dishwasher constructed in accordance with the present invenion, illustrating its application;

Figure 3 is a fragmentary vertical sectional view of a water supply pipe constructed in accordance with the present invention removed from the container top;

Figure 4 is a perspective view of the article containing rack of the present invention showing parts of the dish supporting rack removed to disclose details;

Figure 5 is a vertical sectional view of the article supporting rack; and

Figure 6 is a detail fragmentary perspective view of a cupsupporting frame; a similar view of water glass supporting frames; and a similar View of plate supporting frames, respectively.

The device of the present invention includes a cylindrical container 1, made of any suitable metal, which container constitutes the washing chamber of th present invention. The top of the container is provided with a protruding annulus 8, the top of which is recessed, as indicated at 9, adapted for the reception of a complemental bead I0 formed on the bottom of the container cover or lid II. The lid ll is preferably of dome shape and equipped with a Water supply pipe I2. The lower end of the pipe is tapered to provide an inner cone shaped terminal I3 which is perforate and adapted for the reception of soap or detergent used for admixture with hot water preparatory to being sprayed into the washing chamber. A supply pipe is provided with multiple series of oblong perforations It which are separated in order to efiect dispersion of the water in predetermined planes and to prevent loss of water pressure. The water supply pipe I2 is fixedly secured to the cover or lid II and, at a point above the cover, the pipe is enlarged, as indicated at I5 and provided with a bayonet slot I6 as advantageously illustrated in Figures 2 and 3. Extending from opposite sides of container I below the annulus 8 are a pair of handles IT. The bottom of the container is provided with an outlet opening in which a plug carried outlet pipe I8 is mounted, as shown in Figures 1 and 2.

Th container I is adapted for the reception of a rack generally designated I9, the rack being constructed so as to support plates, saucers, cups, glasses, silverware and other articles to be washed. The rack includes a ring base 20 with upstanding frames 2 I, the frames being arranged in spaced, parallel relation adapted to receive plates, saucers or like articles which are to be Washed. It will be noted that the frames are disposed so that the plates or other dishes supported therebetween will be closely positioned in order to effect impingement of both sides of the dishes by the water supply pipe I2, in a manner more fully hereinafter described. The rack further includes a centrally arranged silverware supporting receptacle 22 which is provided with a reticulat bottom 23. The outer periphery of the silverware supporting receptacle 22 is engaged by a .3 platform generally designated 24, the platform being composed of radially extending bars 25 which support spaced circularly arranged wires 26. The rack 19 further includes frames 21 adapted to support water glasses. Each of these frames consists of a pair of wires the upper terminals of which are bent downwardly and the free terminals reversed to provide hooks 28 which embrace the open ends of the glass as shown in Figure 6. The glasses are radially mounted on the frames 21', to directly receive water dispersed from the axis of the washing chamber through the supply pipe l2.

It will be noted, especially upon reference to Figures 4 and 5 of the draw-;- ings, that e pper terminals of the racks 21 fall below the tops of the frames 2|. Cup supporting frames 29 also form a part of the rack l9. Each of the frames 29 consists of vertical wire three minutes.

stock, the top of which is bent downwardly and l the terminal formed to provide a lateral hook 30, the bill of the hook bent downwardly as indicated at 3|. In use, the hook 30 is adapted to engage a cup handle and, in view of the curvature of the hook bill, the interior of the cup will be directly exposed to water sprayed from. the axis of the chamber through the supply pipe i2. The upper ends of the frames 29 are in a plane above the upper ends of the frames 21 so as to directly receive water sprayed from the supply pipe l2.

In order to connect the washer with a faucet or other source of water supply, I provide a flexible connector 32, made of rubber or other suitable material, the opposite ends of which are equipped with couplings 33. Each of the couplings 33 has one end thereof tapered and threaded to facilitate its engagement with the connector 32. The opposite end of one of the couplings 33 is provided with lugs 34 which are adapted for engagement in the bayonet slot l6 of the supply pipe enlargement 15. The opposite end of the other coupling 33 is enlarged and provided with bayonet slots 35 which are adapted for engagement with lugs 36 carried by a faucet fitting 31. The faucet fitting may be engaged with the faucet through the medium of screws 38 or the like.

In use of this device the articles to be washed are positioned in the rack after the fashion shown in Figure 6. Following this procedure, plates, saucers, and the like, as indicated at 39, are preferably mounted between adjacent frames 26 while cups 48 are engaged with hooks 30 of frames 29 and glasses 4! slip over the hooks 28 of frames 2'1. Other articles to be Washed, such as coasters, etc., may be mounted'on the platform 24 while the silverware and the like is preferably mounted in the receptacle 22. After the articles have been so positioned, the cover or lid H is engaged with the top of the container 1 and the upper coupling 33 engaged with the faucet fitting Hot water is adapted to be supplied to the washing chamber through the perforations H of the water supply pipe 12. The water may be mingled with soap powder or the like, as set out supra, placed in the conical lower terminal of the supply pipe 12. Water is sprayed out through the lower series of perforations in engagement 4 with silverware and other articles carried by the receptacle 22. The soap charged water is also sprayed out through the intermediate series of openings [4 into engagement with the plates, saucers, cups, glasses, etc., supported by the frames 2 I, 21 and 29 and also on the articles carried by the platform 24. The faucet water will be ejected directly through the uppermost series of perforations l4 so as to effect a rinsing action of all the articles carried by the rack [9. Before the dishes have been washed, the stopper is removed from the outlet pipe [8 to permit the contents of the washing chamber to be drained. In actual use, it has been found that the average dishes may be washed, in accordance with the teaching of the present invention, in less than It is of the essence of importance in the present invention that the perforations M of the water supply pipe l2 be substantially oblong in construction so that the ejected water, in engaging the corners of the openings, will be effectively dispersed as contra-distinguished to a. rounded spray which has been found unsatisfactory. It is unnecessary to employ any extraneous means for effecting a flow or circulation of water through the articles being cleaned. Ample pressure is provided by the faucet water gravitating intothe connector 32.

While I have herein shown and described the preferred form of the invention, it is of course to be understood that various changes may be made within the scope of the claims hereto appended.

What I claim is: 1.;A dishwasher including a dish container, a dish rack detachably mounted in the container, the dish receiving elements of which are radially disposed and directed, and a water supply pipe mounted in the container and provided with oblong perforations elongated circumferentially 01' the pipe, the pipe being positioned to effect impingement of both sides of the dishes by water sprayed. through the supply pipe.

, 2'. A dishwasher including a dish container, a dish rack detachably mounted in the container, the-dish receiving elements of which are radially disposed and directed, and a water supply pipe concentricallyzmounted in the container and rack-the pipe being provided with spaced series ofhorizontal oblong perforations elongated cir-q cumferentially of the pipe. one of which series eifects impingement of water against both sides of thedishes, another series effecting a spraying of the dishes, f rom above, for rinsing the dishes.
