concern:

Be it known t t I, JosnrH J. SLEEPER, a citizen of the United States, residing at Moores, in the county of Delaware and State of Pennsylvania, have inventedcertam new and useful Improvements in pish washmg Machines, of which the following is a specification.

My invention relates to 1m rovementsm dish washing machines, an ob ect of the 1nvention being to provide an improved construction of agitator movable in a well 1n the base of a dish containing receptacle, and adapted when moved in the well to throw the water in various directions to thoroughlwash the dishes. 3

A i irther object is to prov1de a Washmg machine and improved constructlon of agitator with means for alternately moving the same in difierent directions and imparting to the water difierent movements during the operation of ,the agitator to thoroughly cleanse the dishes;

A further object is-to EIOYldG an mproved dish washing machine. aving an v mproved arrangement of rotary agitators in a confined receptacle, and having improved means for permitting a free communication with the outside air so as to insure normal conditions within the receptacle and prevent partial vacuum or pressure which would interfere with the perfect washing of the dishes.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in vertical section illustrating my improvements. Fig. 2 is a View in elevation at right angles to Fig. 1 with the upper portion of the receptacle shown in section.

Fig. 3 is a view in horizontal section on the line 33 of Fig. 1. Fig. 4 is a top plan view. Fig; 5 is a fragmentary view in elevation showing a modified arrangement of agitators illustrating the same in connection with the receptacle well, a portion of the latter being shown in section, and Fig. 6 is an enlarged view in longitudinal section on the line 6-6 of Fig. 5.

1 re resents a receptacle having a well 2 its ottom, said well and receptacleboth preferably of circular shape in horizontal section with the outer walls of the receptacle and well concentric, but the latter appreciably smaller in diameter than the receptacle proper so that a circular ledge 3 is formed to support wire baskets to contain the dishes to be washed. These Wire baskets are preferably composed of ordlnary Wire covered with fiber, cork, or any other suitable material as indicated at 5 to prevent chipping the dishes and cushioning the contact of the same with the baskets. I preferably provide feet 6 to support the machine, and in the bottom of the well 2, an outlet 7 is formed having a discharge pipe 8 extending at an angle therefrom and normally closed by a stopper 9.

' The upper end of the receptacle 1 is closed by a removable cover 10, the latter consisting of three parts 11, 12, and 13. The intermediate portion 12 is provided with overlapping flanges 14: which are secured by bolts 15 and Wing nuts 16 to the sides of the receptacle 1. The sections 11 and 13 are connected by hinges 17 with the intermediate section 10, so that they may be readily moved up and down to permit access to the receptacle.

The intermediate section 12 of the cover 1 has a central bearing 18 for a vertical tubular shaft 19, and the latter having a beveled pinion 20 on its upper end meshing with a beveled ClIlXG gear 21. The gear 21 is supported upon ashaft 22 carried by brackets 23 on the intermediate section 12, and back of the gear 21, I preferably locate ball bearings 24 to sustain the thrust and hold the gear up to its meshing position with pinion 20. An operating lever 25 is secured to turn with the gear 21, and is adapted to be oscillated so as to impart a rotary movement to the shaft 19, first in one direction, and then in the other as will more fully hereinafter appear.

TheloWer closed end 26 of shaft 18 has a thrust bearing 27 on a pin 28 fixed in the bottom of the well 2, and to the shaft 19 near its bottom, horizontal bars 29 are rigs idly secured. On these bars 29, my im, proved agitators 30 are secured. l Vhile the invention is of course not limited to any particular manner of connecting the agitatorswith the shaft, I preferably provide bolts 31 as shown, nor is the invention limited to any particular number of these agi- 4 adapted tators, as for example, in Fig. 3 I have illustrated two agitators, and in Fig. 5, four.

These agitators 30 are preferably formed of sheet metal and have deflecting

surfaces

32 and, 33 at an angle to each other, and at different angles relative to the bottom of the well. These

surfaces

32 and 33, as well as the bottom 34 and sides 35 may be formed from a single sheet metal blank.

In Fig. 5, I have illustrated two pairs of agitators, and it will be observed that the outside agitators have their outer walls 36 at an angle to the side walls of the well, and it is to be understood that the above angles of the different walls of the agitators result in imparting different movements to the water in the well as will be explained.

It is to be understood that the well will contain water up to a point approximating 2 its upper end, and this is allthe Water there will be in the receptacle. In the bottom of a the well or rather at a point slightly re-.

moved from the bottom, a wire screen 37, is located. This screen has two important functions, first, it permits solid particles to pass through the screen and retards their upward movement, and secondly, the screen serves to retard the rotary movement of the water which augments the angular throw of the water by the agitators.

As above stated, the shaft 18 is tubular or hollow, and this shaft. communicates at its upper end with the outside air and throu hout its length in the receptacle is provi ed with perforations 38, so that the air inside the receptacle has free communication with the outside air. This prevents either pressure or partial vacuum and prevents an undesirable accumulation of soapy bubbles 40 around the dishes.

Assuming the baskets 4: to be full of dishes to be washed, and well 2 full of water which I may be impregnated with soap or any cleaning composition, when the lever 25 is oscillated, shaft 18 will be'revolved in one direction, and then in the opposite direction. During the first movement, the inclined surface 32 Will throw the water in one direction, and on the reverse movement, the in- 5o gclined surface 33 will impart a different f movement to the water. The inclined outer jw'alls 36 will also give the Water an upward "-1 f swi'rling movement, and these combined jmovements imparted to the water will in- 5 5 'su re 'a perfect cleansing of the dishes, as all parts-tr the dishes will be subjected to contact with the water which will be thrown with considerable force. In the normal 0p- ,eiation of the device, these varying move u ments given to the water may of course be -altered by changing the angles of the difierentj surfaces, but I believe the particular -"shape illustrated is a preferable one because of the many different movements attained.

" After the dishes are washed, the dirty Water may be allowed to drain 0E, and clear hot water supplied to the well, and the dishes thoroughly rinsedand allowed to dry.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a washing machine, the combination with a receptacle, of an agitator movable in the receptacle adjacent the bottom thereof and in a path concentric with the center of the rece tacle, said agitator having deflecting suraces at its respective ends at an angle to each other and at different angles relative to the bottom of the receptacle, and means for moving the agitator in opposite 0 directions, substantiall as described.

2. In a washing machine, the combination with a receptacle, a vertical shaft in the receptacle, and agitators connected to and movable by the shaft in a circular path ad- 35 jacent the bottom of the receptacle, said agitators'having at their respective ends water deflecting surfaces at'an angle to each other, and means for imparting a rotary movement to the shaft first in one direction and then in the other, substantially as described.

3. In a washing machine, the combination with a receptacle havin a concentric .well in its bottom of appreclably 'less diameter than the receptacle, 9. screen in the well spaced from the bottom thereof, a rotary shaft positioned vertically in the well, agitators at opposite sides of the shaft and secured to turn therewith, said agitators hav ing water deflecting surfaces at both ends and at both sides at various angles, and means on the upper end of the receptacle for imparting a rotary movement to the shaft first in one direction and then in the other, substantially as described.

4. In a washing machine, the combination with a receptacle having a concentric well in its bottom of appreciably less diameter than the receptacle, a screen in the well spaced from the bottom thereof, a rotary shaft positioned vertically in the well, agitators at opposite sides of the shaft and se cured to turn therewith, said agitators having a plurality of water deflecting surfaces at various angles, said shaft tubular in form 1 5 communicating'at its upper end with the outside air and perforated throughout its length, and means for turning the shaft in opposite directions, substantially as described.
