Patented Sept'. 1.5, 1935i @UNITED STATES PATE NT OFFICE vEBN'ES'I J. BISKAMP, 0F SAN ANTONIO, TEXAS msawasnm s This invention relates to dish washing machines. One of its objects is to provide a portable structure which can be set up readily in a sink, on a drain board, or on a suitable stand 5 and, by connectin it to a hot water faucet, can be actuated e ciently without requiring the use of a motor or any mechanism of a complicated and expensive nature.

Another object is to provide an apparatus 0 of this character through which there' is a constant iiow of fresh water which serves not only to thoroughly clean the contents of the washer but also to promptly remove the foreign substances.

parts of which are easily accessible or'the purpose of cleaning them or making repairs. v

A still further object is to provide a washer utilizing superposed rotatable spraying elements between which may be placed the articles to be washed, the upper element or elements being removable with the cover of the washer thereby to permit convenient placing of the dishes, etc. in 'position to be washed. p Another object is to combine with the machine a simple and eiicient means for sup plying soap to the water being directed onto ,the articles being washed.

With the foregoing and other objects in View which will appear as the' description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the .invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention. In the accompanying drawings the rpre- 'ferred forms of the invention have been shown. In said drawings,

for holding dishes and other articles to be l cleaned.- If preferred, however, and as shown in Figure 12, the casing can be provided with fone or more ribs 5 pressed inwardly therefrom for supporting the racks.

In the structure illustrated there yis provided a lower rack and an upper rack. Both racks are formedof sti wire. The lower rack 6 includes a ring 7 across which are extended interwoven wires 8 widely spaced so as to offer the minimum obstruction to the ow ofwater. Certain of the wires have their middlev portions bent to` form upwardl extending inclined yokes indicated at 9. hese okes, as shown particularly in'Figur-e 1, are

dishes-in mclmed positions and spaced apart. The dishes have been indicated by broken lines at D.

As illustrated in Figure 2, the upper rack 10 is formed of a wire ring 11 having inwardly extended spaced parallel portions 12 which merge into a central inner ring 13 concentric with the ring 11. The inwardly extended portions 12 and the inner ring 13 are connected to the ring 11 by crossed interwoven wires 14. Additional wires 15 which are likewise interwoven,`extend across and are connected to the ring 11 at points where they are not intersected by ring 13 or the inwardly extended portions 12. The rack constructed as described is left with a central clearance 16 from which extends a radial clearance 17 opening through the margin of the rack.

Extending from the bottom portion of casing 1 is an outlet spout 18 and securely fastened to the outer side of the casing by any suitable means is a distributing pipe 19 the lower portion 2O of which is extended under the bottom of the casing and opens into a spraying pipe 21 which will be hereinafter more fully described. The upper end of pipe 19 is connected by a quick detachable coupling 22 of any desired construction to a distribu ying pipe 23 which extends over and is suitably connected to the cover 24 of casing 1. This cover is removably mounted on the casing and can be lifted by means of a bail 25 or by means of knobs 26 shown in Figure 13. I

Distributing pipe 23 opens into a pipe 27 which projects downwardly through the center of the cover 24. As shown particularly in Figure 9, this pipe 27 is engaged by a nut 28 which rests on the cover 24. A spacingwasher or nut 29 extends around the pipe 27 and engages the bottoni surface of the cover. This spacing element is adapted to receive thrust from a hollow hub 30 rotatable on the pipe 27 and supported by a collar 31 which is detachably secured to the said pipe. The lower end of the pipe 27 is closed by any suitable means such as a screw plug 32 and communication is constantly maintained between the interior of the said pipe and the interior of the hub through apertures 33.

A spraying pipe 34 extends radially from thehub 30 and opens thereinto. This pipe eX- tends close tothe wall of the casing 1 and is suppprted close to the cover 24. It has a series of apertures 35 extending longitudinally thereof, these apertures being inclined downwardly in such a direction as to cause the pipe and hub to rotate when water or other liquid 1s discharged through the apertures.

Another pipe 36 is extended from the hub 30 downwardly through the clearance 16 and opens mto and supports a spraying pipe 37 arranged under but close to the rack 10. This spraying pipe is of'a length less than the combined lengths of the clearances 17 and 16 so that, when the pipe is positioned beneath said clearances, it can be withdrawn upwardpipe and the hub 30 -to rotate in the same direction as these parts are propelled by water issuing from pipe 34.

The lower pipe 21 is constructed the same as pipe 27. 'lhe hollow hub 40 which is rotatably mounted thereon has spraying pipes 41 and 42 extending radially therefrom. Both of these pipes have upwardly inclined apertures 43 arranged in longitudinal series for directing jets of water upwardly toward raclr4 6 and at the same time rotating the pipes and the hub 40 in a direction opposite to that in which the upper hub and its pipes rotate.

F or the purpose of limiting the rotation of the hub 30 and the pipes carried thereby, a yieldingly supported plunger 44 is slidably mounted in the cover 24 and is normally held out of the path of pipe 34. This plunger has a head or button 45 by means of which it can be depressed readily to bring the plunger into the path of pipe 34. Thus the pipe will be brought to a stop by the plunger at a point where the pipe 37 will be positioned under the clearances 16 and 17. Consequently, by uncoupling distributing pipe 23 from distributing pipe 19, the cover can be raised and pipe 37 can move upwardly through the clearances without disturbing the rack 10 or any of the articles supported thereby.

The distributing pipe 19 has a nipple 46 opening thereinto. This is adapted to be detachably engaged by a soap container 47. The outlet end of the container may be provided with a screen 48 for preventing particles of soap from flowing into the machine. A hose 49 is connected to the other end of the container and constitutes a means for directing hot water from a faucet or other outlet to the machine. The soap container 47 can be connected to the nipple 46 by means of a stud 5() adapted to be received by a bayonet slot 51 as shown in Figure 1 or it can be screwed onto the nipple as shown at 52-in Figure 10. A small cake of soap indicated at S is adapted to be held loosely in the container 47 so that the water flowing through the container will slowly dissolve the soap and carry it to the spraying pipes.

If desired, liquid soap can be supplied to the machine. For this purpose a soap container 53 can be supported upon and open into a container 54 similar to container 47 Soap container 53 has a normally closed inlet 55 at the top thereof and a by-pass 56 extends from container 54 to the top of container 53.
