FREDERRK \VM. IIOIPE, OF BAS'IROP, TEXAS DISH-WASHER.

SPECIFICATION forming part of Letters Patent No. 460,778, dated October 6, 1891.

Application filed January 14,1891. Serial No. 377,738. (Modeln To all whom it may concern.-

lie it known that I, FREDERICK In. I IoPPE, acitizon of the United States, residing at Bastrop, in the county of liastrop and State of Texas, have invented certain new and useful Improvements in Dish-\Vashers; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the samc,refcrence being had to the accompanying drawings, and to letters of reference marked thcreoinwhieh form apart of thisspecification.

The object of my invention is to furnish an improved means for washing dishes in such a manner that all foreign substances, greasy matter, and offensive odors maybe readily and expeditiously removed and the dishes restored dry and clean by the operation of the machine Without handling them.

The invention therefore consists in certain novel arrangements and combinations of parts, as will be hereinafter set forth, and linally embodied in the clauses of the claims.

In the accompanying two sheets of drawings, in which similar letters of reference are employed to indicate corresponding parts in each of the different views, Figure 1 is a front elevation of my improved machine. Fig. 2 is'a side elevation of the same, looking toward that side of the machine to which the operating mechanism is attached; and Fig. 3 is an enlarged vertical section. On Sheet 2, Fig.4 is a horizontal section taken through line .2 in Fig. 1, and Fig. 5 is a top or plan view of a removable dish-supporting frame used in connection with my machine. Fig. (i is an end view of the same. Figs. 7, 8, and 9 are views of adjustable racks shown in part, each being provided with differently shaped dish-holding arms orfingers. Fig. 10 is an end view of one of the adjustableraeks, and Fig. 11 is a side View of one end of such racks.

In said views, A indicates the inclosing" boxes a and a in the opposite sides of the casing A. One end I) of said shaft terminates in the stufling-box a, as will be seen from Fig. l, and a hot-water or steam supply pipe c is tapped into said stuffing-box, connecting with said end I) of the hollow shaft 13, while the opposite end of said shaft passes entirely through the stuffing-box a and is closed by means of a nut or plugh. As will be noticed from Fig. 4, said shaft is provided with any desirable number of small holes or perforations Z), throughwhich the hotwatcr or steam is forced upon the dishes supported upon the racks (I, as will be more fully describeu in the following description.

The casing A is preferably provided with inclined sides at the bottom and is supported by means of the standards A and A The bottom of the tank or casing A is provided with an outlet a from which the'dirty water is drawn off in a constant stream when the machine is in operation, or said pipe in the outlet may be provided with a faucet, if desirable.

The mechanism for producing an oscillatory motion of the hollow and perforated shaft B consists of the forked arms a and a pivoted at the side of the machine to the frame or standard A one of which, as a is provided with a handle ortion a and a rope or belt a is passed over the shaft B and around a pulley 'i thereon, and is attached at its ends in holes a and a in the respective arms (1 and a, as clearly illustrated in Fig. 2.

The opposite sides of the casing A are provided on their inner surfaces with any number of cleats e, which are formed with the ways or guides e, projecting out at right angles, upon which I arrange the racks (I so that they slide thereon-and can be adjusted in any desired position, or said racks can be entirely removed from the machine for cleaning when necessary.

Directly above the shaft 13, I have secured a second set of cleats 6 upon which is placed a frame F, (shown in Figs. 3 and 5,) which is provided with any number of the dish-holding racks (I, said frame and the racks supported thereon being entirely removable from the casing A. As will be seen from Figs. 3, 5, and 6, said frame F consists of the end por- IOO tionsfandf and a dividing portion or wall said portions being secured together by the side strips f and f", the whole constituting the frame F. The portionsf and f are .provided with a suitable number of cleats f upon which areplaced the adjustable racks (1, similar in construction to those used in the bottom of the casing upon the cleats e.

The walls or portions f andf are provided with flan ges f and f and to these and flanges f and f on the strips f and f I arrange a wire netting or screen g,-provided with upwardly-projecting hooks g.

The ends of each rack (l are formed into forks d, by means of which they can he slid upon the cleats and adjusted in any position thereonor entirely removed therefrom when necessary. Said racks dare provided with fingers or arms (1 preferably made from spring-wire, which may be hook-shaped, as shown in Figs. 4 and 5; or said racks may be provided with straight fingers (1 as in Fig. 7, or with the curved fingers d, as in Fig. 8, or with the fingers (1. (Shown in Fig. 9.)

. \Vhen it is desirable to wash the dishes, I place the plates upon the racks (I, as indicated in'dotted lines in Fig. 4, so that the circumferential edge of the plate rests upon a lower and is supported by two parallel and higher-placed racks d, whereby said spring fingers d on the several racks engage with the opposite sides of the plate and hold the same in position between three of said racks.

The hooks g on the wire netting g are employed for the hanging of cups thereon.

Owing to the adjustability of the racks (1 upon their cleats they can be moved closer together or farther apart, as may be necessary, whereby a saucer can be supported be tween said racks as well as the largest plate, as will be evident.

When the plates and cups have been placed in the machine, the hot wateror steam is admitted into the hollow and perforated shaft B, which,by means of the operating mechanism on the one side of the machine, is made to oscillate in its stuffing-boxes or bearings a and a. By this operation constant streams of hot water or steam are ejected from the holes in the shaft, which strike the dishes at the desired angles and with great force, being' deflected from one plate upon another, &c., and thereby thoroughly cleansing the same, while the waste water passes off through the outlet at in the bottom of the casing. WVhen the dishes have been thoroughly rinsed for aproper length of time, the water or steam is turned off and the operation of the shaft ceased. The dishes are allowed to dry in th machine. r

The cover A can be removed or thrown back on hinges-and the frame F taken out is no danger of the dishes becoming broken because of their remaining when placedin the machine in stationary positions.

The water from the shaft B is thrown against all sides of thc dishes, a free passage of water being permitted between the same, which accelerates the washing process.

Having thus described my invention, what I I laim is- I 1. In a dish-washing machine, the combination, with the casing and perforated and hollow and rotatable shaft for the supply of hot water or steam, of removable and adjustable racks provided with forked or hookshaped ends adapted to slide on cleats in said casing, for the purposes set forth.
