DISH-WASHING MACHINE.

Specification Of Letters Patent. tpawtcgmtd dpr.. 25, 1916.,

Application filed @ctober 21, 1915. .Seria-1h10. 57,122.

To all whom it may concern:

Be it knownthat l, WILLIAM A. CARSON, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful improvements in Dish-Washing Machines, of which the following is a specification.

This inventiony relates to a machine for washing dishes, and other similar articles used in the preparation and serving of lfood, and to a novel construction and arrangement of its component parts.

In carrying into effect the present invention, I employ a trough-like chamberfor the cleansing Huid, and a shaft Within the chamber, having a series of splashers arranged to carry the fluid into forcible contact with the dishes and other articles which are' supported within an open receptacle immediately adjacent the splashers.

Among the objects of my invention l have sought to provide a machine which is simple and inexpensive, and effective for Washing dishes as Well as other articles, such as glassware and cutlery; a machine which will operate with equal effectiveness, regardless of the directionin which the splashers may be rotated; and a form and construction of splashers which will insure the greatest eficiency in the'washing operation. These and other objects of my invention will more fully hereinafter appear from the specification vand claims, and 'from the drawings in which Figure 1 is a vertical section through a Washing machine embodying ,the principles of my invention; Fig. 2 isa horizontal section through the machine, taken on line 2 2 of Fig. 1; the basket being removed in this view; Fig. 3 is a transverse section throughv the machine, taken on line 3--3 of Fig. 1; y

and Fig. el is a detail, in perspective, showing one of the splashers which are mounted upon the shaft.

A representative embodiment of my in# vention is shown in the drawings in which is exhibited a housing 5, the bottom portion 6 'of which is shaped to provide in eHect ay trough for the cleansing fluid. The housing may be supported on legs 7, as shown.- rll`he upper portion 8 of the housing is shaped to provide a chamber for the reception of an open basket 9, arranged to seat upon brackets or braces 10. This basket I prefer to equip with a series of racks 11 against which dishes may be stacked, these racks being conveniently formed of wire or other similar material bent in zig-zag form and arranged in parallel courses. A smaller basket 12 is also shown, within which articles of cutlery may be placed for the washing operation.

rllhe housing is rendered watertight by the use of a cover 13, which may be secured in place by anyappropriate means.

Extending from one end of the housing to the other is a shaft 14, preferably square in cross section. rllhe ends of this shaft are suitably journaled withinr bearings 15, one end 16 of the shaft extending through the housing to the exterior thereof. Upon 4this end of the shaft a sprocket wheel 17 is mounted.y A. sprocket chain 18 passes over the-wheel 17, and over another wheel 19 of relatively greater diameter, which is rotatably mounted upon the exterior of the housing. A handle 2() is secured to the sprocket wheel 19 for the purpose of4 rotating the same, in consequence of which the shaft 14 may be revolved at high speed. A series of snlashers 21 are mounted upon the shaft 14, being arranged progressively 90 apart. As best shown in Fig. 4, these splashers consist of two complementary sections, each convenientlyl formed from a single piece of material by the use ofa die. Fach of these sections moreover is constructed to provide a relatively hollow portion 22, side walls 23, and an inclined end Wall 24. The end of each section which is secured to the shaft 14 yis also shaped to squarely embrace the shaft, a portion 25 thereof being ex.-

tended a slight distance to overlie the shaft.

y,used considerably, and where it is required that frequent changes of water be made in the housing. The manner in which these splashers are arranged upon the shaft is of special importance. As appears 1n the drawings. the splashers are'arranged progressively 900 apart, two splashers separated `ceding splasher. `which I have adopted, such an ineiiicient by a considerable distance being alined on the same side of the shaft where eight splashers are employed, as shown. It is manifest as soon as two splashers are revolved out of the body of the cleansing uid that the adjacent splashers* situated 90o l therebehind, will be' the. next to leave the body of the fluid, and so on. In this manner the liquid is agitated-progressively in different sctions, 'corresponding to the planes in which the, several splashers are located. This action of the splashers in a high speed machine is morejeifective than any other, since otherwise each splasher would be required to -work in a void within the liquid body created by the movement of the pre- Under the arrangement principle of operation is overcome, each splasher performing its work at points where the water is at the moment relatively undisturbed.

In throwing the water forcibly into contact with the dishes to be cleansed, the form water from the splasher shortly after it has ularly effective.

' -that the side walls 23 retain within the hollow portion of each' splasher a considerablev of splashers, best shown in Fig. 4, is partic- This is due to the fact quantity of water, which by centrifugal action is discharged over the inclined end 24 of the splasher. The action of these splashers is comparable to that of a bucket to the extentv that a certain quantity of water is lifted `out ofthe body of liquid which fills the lbottom of the housing, but is dissimilar in that the inclined Yend wall 24 is shaped to facilitate the discharge ofpractically all the which interferes-with the action of the other,

yet either of which may operate independently of the other when the shaft 14 is rotated in the proper direction. It may frequently be desired that the splashers be revolved first in the one direction and then in the other, for the purpose of directing the action of the water upon the dishes from opposite sides of the housing, and such a re-- ers mounted radially upon the shaft and arranged to be revolved through the body of the liquid, said splashers being provided eachwith a hollow portion, the bottom of which is in radial relation to the shaft, each of the splashers having an end wall inclined with respect to its bottom over which liquid may be discharged by centrifugal action when the splasher is rotated 1n the proper direction, substantially as described.

2. A dish washing machine including, in combination, a liquid retaining receptacle, a rotatable shaft, and a plurality of splashers carried by the shaft arranged to be revolved through the body ofthe liquid, said splashers comprising each two (2) 'complementary sections secured back to back with a portion of each embracing the shaft, and each said splasher section being provided with a hoilow portion and an inclined end Wall over which liquid may be discharged by centrifugal action when the splasher is rotated in the proper direction, substantially as described.

3. In a machine of the class described, the combination with a shaft of a splasher consisting of two (2) complementary sections,

each formed with side walls and inclined end walls, the end wall of each section adjacent the shaft being extended to overlie and embrace the shaft, and means for securing each sectionto the other, said means serving also to lock the splasher upon the shaft, substantially as described.
