DISH-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 569,606, dated October 20, 1896.

Application filed June 19,1895. Serial No. 553,325. (No model.)

T @ZZ whom, t Irl/ty concern.-

Be it known that I, GEORGE S. BLAKEsLEE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dish-VVa-shin g Machines, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a front elevation. Fig. 2 is a side elevation. Fig. 3 is a vertical section taken at the line :l: a: of Fig. 1, and Fig. et is a detail of the devices for shifting the rotating dish-basket into or out of engagement with the driving mechanism.

This invention relates to machines for washing dishes, and has for its object to provide new and improved means whereby the machine will accomplish the work for which it is design ed in a complete and thorough manner without necessitating the handling of the dishes after they have been placed in the machine.

The invention also has for its object to provide novel means for easily and quickly lowering a dish-carrier into scalding water in the lower part of a receptacle, rotating the carrier while loaded with soiled dishes, raising the carrier with its load above the surface of the water, and rotating the carrier while in its elevated position and subjected to the action of hot clean water.

These Objects are accomplished in the manner and by the means hereinafter described and claimed.

In the drawings, 1 indicates the body of the machine, such 'body in the form shown consisting of a rectangular box of any suitable material. As shown, the front wall of the box extends from the bottom up about half the height of the box, leaving a long wide Opening 2, through which the dish-.baskets are passed to and Withdrawn from the machine. An apron 3, Wound on a suitable roller that is journaled in the side walls of the box, near the upper edge of the front wall of such box, is provided, which can be drawn up and held in place to cover the opening 2 to prevent the escape of water and steam when the machine is in operation.

a lindica-ies suitable legs or supports for the box 1. Y

5 5 indicate two guides secured to opposite inside faces of the box 1. As shown, each guide consists of a single bar bent to an approximately U shape, but with one side or leg longer than the other, such longer sides of the guides being toward the rear ofthe machine.

G indicates a rod or bar extending across the machine from near one side wall to near the Opposite one and about midway between the front and rear of the machine. Each end ot' this rod or bar G is bent to forni adepending portion 7, which depending portions are slidingly connected to the long sides or legs of the guides 5 5 by collars 8. Each depend ing portion 7 has formed on its end a curved portion 9, which serves as a bearing for the trunnion on the end of the dish carrying basket.

10 indicates a dish-carrying basket of any usual and approved form that is adapted to securely hold in proper position dishes of varying shapes while being rotated in a body of water or under a stream or sheet of water.

On one of the trunnions of the basket is keyed a small gear-wheel (represented by dotted lines at 11 in Fig. 4) adapted to be engaged by either one of two other gear-wheels, according as the basket is raised or lowered, by means of which and other coperating devices rotation can be imparted to the basket.

Before describing the means by which the rotation is effected I will describe the devices through which the operator is enabled to lower the basket into the body of water in the lower part of the box 1, and afterward ele.

vate it and the dishes therein out of the water preparatory to subjecting the said dishes to another and final cleansing operation.

Referring to the drawings, and particularly to Fig. 1 thereof, it will be seen that secured to the rod or bar 6 near its center are two' chains, (indicated by 12 and 13,) the former of which passes over a pulley 14, suitably secured to a framework 15, bolted to the top of the machine, from whence it passes over another pulley 1G and then down and alongside one of the side Walls, a counterbalance-weight 17 being attached to its end. The other chain, 13, passes over a pulley 1S, thence over a pulley 19, located near one of the rear upper corvners of the machine, and then down to and IOO connected with the end of a lever 20, pivoted at 21 to the outside of one of the end walls of the box 1 and held in its adjusted position by a keeper 20. When dirty dishes are to be washed, they are packed in the basket outside of the machine,after which the basket is closed and locked to properly retain them and then lifted up and passed through the opening 2, the end trunnions of the basket sliding upon inclined tracks or ways 22, secured upon the inner faces of the sides of the box. By means of these tracks or ways upon which the baskets trunnions slide such basket is properly and easily directed into the curved ends 9, that form the bearings `for the said trunnions. To lower the loaded basket into the water in the lower part of the box l, the forward end of the lever 2O is pulled down, which permits the bar G, to which the basket is attached, to descend, it being guided in its descent, and also when being returned to its uppermost position, by the guidev 5, to which ther bar 6 is slidingly connected. The action of the weight 17, that is connected to the bar 6 through the medium of the chain l2, prevents the basket descending with undue swiftness and also aids in elevating the same.

23 indicates a short shaft projecting through one of the side walls of the box l ashort distance above the upper edge of the front wall of said box, and at its inner end has keyed to it a gear-wheel 24.

25 indicates a crank attached to the outer end of the shaft 23.

26 indicates a short sleeve on the inner end of the shaft 23, the inner end of whichsleeve carries a bracket 27, (see Fig. 4,) to which is j ournaled a gear-Wheel 2S. On the outer end of this sleeve is an operating-handle 29, which is held in its adjusted position by a keeper 29a. Inserted in the same side wall of the box, but near the `bottom thereof, is another short shaft 30, which passes through a suitable stufling-box 31. On the inner end of the last-named shaft is keyed a-gear-wheel 32, which mesheswithanother gear-wheel 33, that is vjournaled in. a bracket 34, formed with or rigidly secured to a short lever 35, which lever 35 is operated by the lever 29, the two levers 29 and 35 being connected together by a rod or bar 36, pivoted to said levers.

37 38 indicate sprocket-wheels keyed, respectively, to the shafts 23 and 30, and around them is placed an endless drive-chain 39, so that the rotation of the sha-ft 23 by the turning of the crank 25 will also rotate the Ashaft 30.

W'hen the basket with its load of dishes has been let downto its lowerinost position, as hereinafter described, the handle 29 is raised to the position shown in the drawings, which causes the brackets 27 and 34, with their respective gear-wheels, to be thrown into the position indicated: by Fig. 4, and it will be seen that when so adjustedv the gearwheel 33 meshes with both the gear-wheel 32l cnthe shaft 30 and with the gear-wheel 11 on the basket-trunnion, so that upon rotation being imparted to such last-named shaft through the means heretofore described, the basket will also necessarily be rotated, causing the dishes contained in thebasket to be rapidly whirled through the water and cleansed. After the basket has been rotated in this, its lowest position, it is to be elevated to the position shown in the drawings, where the dishes are subjected to another and different operation-that is, rinsing and drying. Before the basket is thus raised, however, the lever 29 is to be reversed, which will cause the brackets 27 and 34 to be swung to one side, carrying with them the gear-wheels 28 and By this operation the bracket 27 and its gear-wheel are carried sufficiently ou t of the line of the gear-wheel 11 to allow such gear-wheel ll to assume the position shown by dotted lines in theupper part of Fig. 4. lVhen it has reached'this position, the lever 29 is again moved upward, which swings the gear-wheel 28 in the bracket 27 into mesh with the gear-wheel ll, so that a rotation of the crank 25 will, through the shaft 23 and gear-wheels 24 and 2,8, rotate the basket. While being rotated in this uppermost position, the dishes in the basket are subjected to the action of very hot water which escapes ina sheet-like form fromalongitudinal opening in the bottom of a spreader 40, placed directly over the basket and extending across the'V box l near the top thereof, to which spreader water is supplied by a pipe 4]., leadying from a boiler or other source of supply.

Near the point of entrance into the box l the pipe 41 is supplied with a valve, to which is connected a short lever 42, to one end of which is connected a spring 43, that acts to keep the valve closed.

44 indicates a chainconnected to theflever 43, which chain passes over a pulley 45, secured near the top of theimachine, and down the side of the machine to-a-foot-treadle 46, pivoted at 47 to the box 1. By pressing down on this treadle the valve in the main supplypipe is opened, so that hot water will be supplied to the spreader 40, `and when the pressure is released from the treadle the action of the spring 43 will close the valve.

47 indicates a steam pipe, from which branch two pipes 48 and 49, through which steam is conducted to the water-holding portion of the box 1` for the purpose of keeping the water therein hot.

50 indicatesv a discharge-pipe, and 51 an overiiow-pipe connected with such dischargepipe.

52 indicates an air-chamber formed of a large pipe on top of the machine, closed at its upper end, and connected at its lower end to the hot-water-supply pipe by a suitable union.

After the dishes in the basket have been thoroughly rinsed by subjecting them to the hot water from the'spreader the hot water is shut off in the manner described, the apron 3 ,let down and run on its roller, as shown in IOO IOS

IIO

Fig. 3, and the basket pulled up and o; from the supports 9 onto the inclined tracks or ways 22, from which it is lifted-out of the machine. The basket is then unlocked and the dishes removed, and from the great heat of the water to which they have last been subjected will be found tc be perfectly dry and bright as well as clean.

The machine as a whole is cheap, simple, and compact, and performs very effective work; and from the construction shown it will be evident that all of its parts are so arranged as to be readily got at for the purpose of making repairs when necessary.

The basket is shown as being raised and lowered in a true vertical line, but it will be readily understood that by slightly altering the positions of the guides the basket may be raised and lowered in a substantially straight line, but at an angle to one side or the other of a true vertical line, and therefore by the Word vertically I wish to be understood as meaning that the basket is noved up and down in a substantially straight ine.

That which I claim as my invention, and desire to secure by Letters Patent, is-

l. In a dish-washing machine, areceptacle adapted to contain water, in combination with a dish-holding basket, guides secured to opposite sides of the receptacle, a supporting device for said basket movably secured to said guides, and devices for raising and lowering said supporting device, substantially as speciiied.

2. In a dish-washing machine, areceptacle adapted to contain water, in combination with a dish-holding basket, guides secured to the sides oi' the receptacle, a cross-bar G having depending portions 7 and curved ends 9 to form bearings on which the basket is supported, a connection between said ends '7 and the guides, and means for raising and lowering said cross-bar and basket, substantially as specified.

3. In a dishwashing machine, a receptacle adapted to contain'water, in combination with a dish-holding basket, guides secured to opposite sides of the receptacle, a supporting device for said basket movably connected to said guides, means for raising and lowering said supporting device, and means for rotating the basket, substantially as specified.
