Application filed November 6, 1920. Serial No. 422,186.

T 0 all whom it may concern:

Be it known that I, CHARLES B. BELKNAP, a citizen of the nited States, residing in the city of Detroit, county of Wayne, and State of Michigan, have invented certain new and useful Improvements in Dishwashing Apparatus, of which the following is a specification.

This invention is an improvement on a similar invention filed as an application April 16, 1919, in the name of Jane T. Belknap, the latter being issued as Letters No. 1,345,059, June 29th, 1920.

This invention relates to improvements in dish washing apparatus and has among its salient objects to provide a construction in which the dishes or utensils beingwashed are simultaneously bodily reciprocated and rotated in a cleansing fluid; to provide aconstruction in. which the utensils being washed are placed in a rack or 'cage detachably mounted on a constantly reciprocating and rotating spindle or shaft,'whereby sufiioient agitation of the cleansing fluidis obtained to thoroughly clean said utensils, and to pro-- vide a construction which is devoid of parts difiicult to clean or complicated in operation and one in which the water for cleansin or rinsing may be maintained at any desired temperature.

The important feature of this invention is the particular type of driving shaft used in connection with. this d'sh washing apparatus.

In the drawings Figure 1 is a vertical side elevation, partly in section, of the improved device.

Fig. 2 is a plan view of the rack or cage. Fig. 3 is a detail view of the reciprocating mechanism.

Referring to the drawings-1 designates a suitable frame on which is mounted a water-tight tank 2 provided with a cover 3. The tank, which is preferably of cylindrical shape, is provided with a centrally disposed vertical extending sleeve 4: having watertight bearings 5 and 6. In these bearin is rotatably mounted a shaft or spindle the upper end of which projects through the caring 6 and is squared to receive the hub 9 of the dish rack 10. Handles 10 are fitted on the,.edge of the rack to facilitate its removal from thetank 2. This rack- 10 is provided with a plurality of removable baskets 11 mounted one above the other, the baskets bemg divided, as shown, to receive plates,

cups, glasses, silverware and the like. It is, of course, apparent that, as the shaft is rotated and reciprocated simultaneously, the rack or cage 10 will revolve within the tank and be raised and lowered with the reciprocation of the sleeve 4.

Describing now the manner of actuating the shaft 7-this shaft is in two parts joined by a tongue and groove connection as shown at 13, the lower end mounted in a lower hearing 12 the upper section of the shaft having a bifurcated lower end 14.- fitting over the vertical tongue 15 of the lower section 7. Through the upper section. of the shaft 7 extends a transverse pin 16 having rotatable ends which are adapted to roll in a slotted passage or groove 18 cut in a sleeve 19, the latter being fixedly mounted upon a bracket 20 riveted or bolted to the frame 1. of the ap aratus. Screw plugs 20 are fitted in ho es in the sleeve and furnish a means for removing the pin 16 from the vertical shaft. On the mounted a worm gear 21 meshing with a similar gear 22 mounted upon theshaft 23 to which power is supplied from any suitable source (not shown). The rotation of the shaft 23 being transmitted to the vertical shaft by the worm tion to the rack containing the utensils to be cleaned. The reciprocatory movement is produced by the travel of the transverse pin 16 in the cam slot or groove 18 cut in the sleeve 19.

The'tank 2 is 'filled with hot water and cleaning fluid, which may be heated by a burner 24: to any desired temperature. Suitable suds, of course, use of soap or like substances.

As the shaft 7 is reciprocated and rotated, suilicient agitation of the water will be obtained to thoroughly and uniformly clean the utensils in the rack. After the dishes or utensils have been washed, the soapy water is drawn oil through a valve 25 and the utensils cleaned with rinsing water, which may also be drawn off through the same valve. By this manner of washing and rinsing the dishes, I am able to subject them to suflicient heat to thoroughly sterilize them, which cannot be accomplished where the dishes are washed by hand, as the complete sterilization of the dishes is not possible" unless the water is at substantially boiling point.

It is understood that the invention is not lower end of the shaft is fixedly gears, gives a rotary molimited in any way to the particular mechacation of the rack within the tank with the nism of reciprocating and rotating the shaft axial rotation. v except as defined in the appended claims. 2.
