DISH-CLEAN ER.

SPECIFICATION forming part `of Letters Patent No. 556,358, dated March 17, 1896.

Application filed March 26, 1895. Serial No. 543,252. (No model.)

To all whom it 11mg/ concern:

Be it known that I, WILLIAM C. MAXFIELD, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented anew and useful Dish-lVasher, of which the following is a speciiication.

This invention aims to provide a machine for washing dishes which will create a current of water through the dish-receptacle when the latter is rotated, thereby facilitating the process of dish-washing and insuring a thorough cleansing of the dishes.

The improvement consists of the novel features which hereinafter will be more fully set forth and claimed, and which are shown in the accompanying drawings, in which- Figure l is a central vertical section of a dish-washing machine embodying the essence of the present invention. Fig. 2 is a sectional View similar to Fig. l, taken at right angles thereto, showing the dish -receptacle suspended within the boiler. Fig. 3 is a bottom perspective View of the dish-receptacle, the upper portion of the crank being broken away. Fig. 4 is a detail view showing the form of a swinging bail,the latter being turned over the edge of the boiler. Fig. 5 is a detail view of a modification.

The boiler l may be of suitable shape and size, being preferably cylindrical in form and constructed of sheet metal, such as block-tin or galvanized sheet-iron, and is provided centrally of its bottom with a vertical journal 2 upon which the dish-receptacle 3 is free to rotate, the latter having a bearing 12 to receive the journal 2. Handles 4 are provided on the sides of the boiler for convenience of handling the latter, and swinging bails 5 are located at diametrically-opposite points, and,

are adapted to swing over the upper edge of the boiler to be engaged by hooks 6 on the sides of the dish-receptacle, whereby the latter is suspended when it is required to drain the water from the dishes or complete the cleansing process by pouring scalding water over the dishes while the latter are held in the said receptacle. These swinging bails 5 are formed from stout wire and have pivotal connection with the sides of the boiler, so as to be turned over the upper edge of the latter when required to support the dish-receptacle. Vhen not in use the bails 5 are turned out of the way, as shown most clearly in Fig. l.

The hooks 6 are broad, and the inner or supporting ends of the bails have a corresponding length, so as to centralize the receptacle and prevent tipping of the latter when held in suspension within the boiler.

The hooks 6 project a short distance from the sides of the dish-receptacle and do not touch the walls of the boiler, thereby offering no resistance to the free rotation of the dishreceptacle when the latter is performing the function for which the machine is designed.

The dish-receptacle 3 is cylindrical in form and closed at its lower end, the upper end being open to receive the dishes and admitting of the same being piled therein. Slots or oblong openings 7 are formed in the sides and bottom of the receptacle. 3, the slots in its sides extending vertically and those in the bottom in radial lines. Hoods or deflectors 8 close the slots or openings '7 on three sides and flare outwardly from the closed to the open side of the said slots 7. The open sides of the hoods or deflectors provided on the sides of the dish-receptacle extend in the same direction, and the same is true of the hoods or defiectors provided on the lower side of the receptacle-bottom, but the hoods or deiiectors on the sides of the receptacle open in an opposite direction to the hoods or deflectors arranged on the bottom of the receptacle, for a purpose which will presently be made apparent. These hoods or detlectors 8 are strips of sheet metal which have triangular-shaped flanges at their ends, and which are secured to the receptacle by solder or other means, so that the strips incline in cross-section away from the side of the receptacle ,to which one edge is attached.

A yoke 9 is attached at its ends to diametrically-opposite points of the receptacle 3, and is provided with a crank l() midway of its ends, by means of which the receptacle is rotated within the boiler. This crank l0 operates through an opening in a conical-shaped cover 1l, by means of which the boiler l is closed. l/Vhen the receptacle is in place it is supported upon the vertical journal 2, and is steadied by means of the crank l0 obtaining IOO a bearing in the opening of the cover 1l, as will be readily understood.

The dishes to be cleansed are piled within the receptacle 3 in any convenient manner, and the latter is placed within the boiler l, the central depression in its bottoin being fitted upon the vertical journal f3, the water for effecting the washing having previously been supplied to the boiler, or it may be sup plied thereto after the receptacle is placed in position and should be of proper temperature to effect the desired result. The machine being in readiness for operation, the cover l1 is placed in position and the receptacle 3 is rotated by means of the crank l0 in the desired direction. If the receptacle travels in the direction corresponding to the open sides of the hoods or deflectors on the sides of the said receptacle, the waterwill be caught up bythe side hoods or deflectors and forced into the receptacle, and will escape through the openings in the lower side of the receptacle-bottom, thereby causing a forced current through the said receptacle from the sides into the receptacle, and from the latter out through its bottoni; but if the recepiacle is rotated in an opposite directionthat is, corresponding with the open sides of the bottom hoods or defleetors-the current will be in an opposite direction that is, through the bottom of the receptacle in an upward direction and out through its sides.

It will be observed by a well-established principle that when the hoods are advanced with their closed sides foremost a suction will be created at the open sides and cause the water to flow therethrough. Advantage is taken of this principle in the construction and provision of the detlectors herein set forth, because one set of deflectors catch up the water and force it into the receptacle, while thc other set by a sucking action draw the water from the receptacle, thereby creating a stron g current of water through the receptacle, which effects the cleaning of the dishes in a comparatively short space of time.

In disposing and providing the hoods or defiectors it is apparent that changes in the form, proportion, and the ininor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Then desired the swinging bails may be attached directly to the sides of the dish-receptacle in such a manner as to swing outward and engage with the upper edge of the boiler and sustain the dish-receptacle in an elevated position therein when draining and drying the dishes after the cleansing process. This is most clearly shown in Fig. 5 by the numeral 5.

Having thus described the invention, what is claimed as new is- The combination with a boiler, of a dishreceptacle rotatably mounted in the boiler and having approximately radial slots in its bottom and vertical slots in its sides, said slots being comparatively long and narrow, hoods or deflectors applied to the bottom of the dislireceptacle and covering the radial slots at one side and at their ends, said hoods having their open sides facing in the same direction, and hoods or deflectors of corresponding shape to those fitted to the bottom of the dish-1e ceptacle secured to the sides thereof and coverin g the vertical slots formed therein at their ends and one side, the vertical hoods having their open sides facing in the saine direction, which is diametrically opposite to the bottom or horizontal hoods, substantially as set forth for the purpose described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
