INVENTOR JOSEPH H. REWEN ERG AT1'ORNEi Patented Dec. 2, 1 9 41 Joseph H. Reifenberg, Mansfield, Ohio, assignor to Westinghouse Electric & Manufacturing Company, East Pittsburgh, Pa., a corporation of Pennsylvania Application November 22,1938, Serial No. 241,807

4 Claims.

This invention relates to apparatus for washing tableware and the like and it has for an object to provide improved apparatus of the kind.

A further object of the invention is to provide an improved dishwasher that may be economically produced.

It is a further object of the invention to provide improved means for supporting the washing unit of a dishwasher within an nclosing casing.

A still further object of the invention is to provide improved sealing means for preventing escape of water from the washing chamber of apparatus of the character set forth. 7

These and other objects are effected by my invention as will be apparent from the following description and claims taken in connection with the accompanying drawing, forming a part of this application, in which:

Fig. 1 is a vertical sectional view of a portable dishwasher constructed and arranged in accordance with my invention;

Fig. 2 is a sectional view taken along the line 11-11 of Fig. 1; and,

Figs. 3 and 4 are enlarged views of the respective gasket and caster structures shown in Fig. 1.

Reference will now be had to the drawing wherein I have disclosed a portable dishwasher constructed in accordance with the invention and including an outer casing l0, a cylindrical washing vessel or tank ll disposed therein and motor driven impeller l2 for projecting washing fluid upwardly within a chamber i3 defined by the vessel H. A rack H for supporting the tableware to be washed is disposed in the chamber l3 and, in accordance with the invention, is carried by a bead l5 formed in the side wall of the vessel ll below the top end thereof. The top of the vessel II is open as shown at It and is provided with a removable closure or lid ll.

The construction of the casing in and the support of the vessel ll therein will now be described. The casing III is preferably formed 'of a sheet metal that is self-supporting so that a rigid frame is not employed. The side walls of the casing ID are bent at the bottoms thereof for defining an inwardly extending lower flange ii) that extends peripherally of the casing. A plurality of supports, such as, for example, casters l9 are employed for supporting the easing ill at respective corners thereof so that the dishwasher may be rolled conveniently from one location to another. Each caster l9 includes a stem 2! that swivels in a bracket 22 which is secured by bolts '23 to the flange l8.

The upper end of the casing l0 supports a top pan 24 including a downwardly extending skirt 25 that encompasses the top margin of the casing Ill and an inwardly extending flange 26. An annular resilient pad 21 is seated on the flange 26 and carries an annular outwardly extending rim 28 formed on the vessel II. The pad 21 defines a resilient support for the upper end of the vessel I I and prevents passag of water to the space intermediate the casing l0 and vessel ll. Preferably, rubber putty is applied to the flange 26, as shown at 2611, for providing a watertight joint between the flange 26 and the pad 21. An annular resilient gasket 29 is secured in any suitable manner to the periphery of the lid I1 and includes a portion 3| that seats uponthe rim 28. A downwardly extending portion 32 of the gasket 29 is annular in configuration and is so formed thatit is biased outwardly whereby it tightly engages the inner surface of the vessel II in the closed position of the lid I1. and 32 of the resilient gasket 29 define a double seal with the vessel H for preventing escape of water during operation of the washer.

In accordance with my invention, the bead i5 is so disposed with respect to the portion 32 of the gasket 29, that water projected upwardly along the inner surfaces of the vessel ll during operation is deflected inwardly andaway from the seal defined by the gasket portion 32 for further reducing th possibility of water leakage past the gasket 29. Accordingly, the bead l5 also functions as a water baflie.

The bottom of the vessel II is formed to support a housing 34 for a pump or impeller and valve mechanism 4l= which respectively effect and control the discharge of fluid from the chamber 13. As the admission of washing water to the chamber I3 and the discharge of vitiated water therefrom form no part of the present in- 0 vention, the devices for eilecting these operations are not shown. A motor 35 is carriedby the housing 34 for driving the pump, not shown, and the impeller l2. The suspended unit including the vessel I i, the pump housing 34 and the motor 35, is subject to vibration due to any unbalance of the rotating parts or to reaction on the propeller l2 when projecting the washing water. Accordingly, the suspended parts recited are subject to lateral vibration.

In accordance with my invention, lateral movement of the motor 35 and housing 34 is restrained by a plurality of stays 35 having their inner ends fixed, for example, to the housing 34 by bolts 31 and their outer ends, respectively, connected to the caster brackets 22 by The portions 3| bolts 38. The stays 36 support, in part, the weight of the vessel Ii, housing 34 and motor 35 and restrain lateral movement thereof. Lateral forces imparted. ,to the stays 3B are transmitted directly to the" caster brackets 22 and not to the casing side walls I. so that the latter porting said casing, and a plurality of stays are relieved of such forces. Accordingly, the I casing l may be of relatively light construction and formed without the use of a rigid frame work. A feature of this construction in which the stays 36 extend from the suspended structure to the caster brackets 22, is the rigidity that is given to an otherwise flexible structure. Accordingly, the portability of the machine over rough or uneven floors is improved as it is understood that without the stays 38, the casing would tend to flex or distort as the casters meet an obstruction on the floor. The connection of the stays 36 to the suspended structure and casters prevents flexing or distortion in the casing. Furthermore, the casing l0 may be safely provided with a vitreous enameled finish which, as is well known, may crack or splinter when subjected to vibration or bending forces, as my improved construction precludes such damage to the finish to the casing l0.

From the foregoing description, it will be apparent that I have provided improved apparatus for washing tableware having a casing structure of relatively light construction which may be economically manufactured and which is not subject to vibration or other forces that may prevail during operation. Furthermore, the leakage of water from the chamber I3 is prevented by my .improved double sealing means and the water deflecting means formed within the chamber.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.

What I claim is: 1. In apparatus for washing tableware or the like, the combination of a container including an impeller and a motor for driving the same, a casing'having side walls for enclosing the container, resilient means carried by the casing and supporting the container adjacent the top thereof, a plurality of supports for portably supbottom portion of the container and connected at their inner ends to the container and at their outer ends to the respective-supports, said.latter connections being independent of the side walls of the casing.
