DISH-WASHING MACHINE.
Application filed March 5,
To all w hom it may concern Be it known that l, GEORGE lV. Coxowm, a citizen of the nited States, residing at Chicago, inthe county of Cook and State of Illinois, haveinvented a new and useful Improvement in Dish-lashing Machines, of which the following is a specific-ation;y
This invention relates particularly to machines adapted to the purpose of washing dishes.
The primary object is to provide a machine of simple construction and moderate cost, which' is thoroughly adapted to the purpose indicated.
The invention is illustrated in its preferred embodiment in the accompanying' drawing, vin which- Figure 1 representsa broken verticalsectional view of a dish-washing machine constructed in accordance with the invent-ion; Fig. 2, a broken sectional view taken as indicated at line 2 of Fig. 1; and Fig. 3, a broken horizontal sectional view taken as indicated at line 3 of Fig. 1.
Iii-the embodiment of the trated, A represents a can, or vessel, which affords a washing chamber, said vessel being provided with a removable top A; B, a cast-iron spider upon which the vessel A is mounted, and which affords a reinforcement for the bottom of the vessel, and affords, also, bearings for various operating parts; B, a frame, or standards, upon which the spider B is rigidly mounted; C, a shaft journaled in the hub-portion of the spider B and having its upper portion projecting into the-lower portion of the vessel A; D, a water-propelling device, or paddle, demountably secured to the upper end of the shaft C; and E, actuating mechanism for the propeller shaft C.
The vessel A may be conveniently formed of sheet-metal, and preferably has its cylindrical vertical wall provided with vertical corrugations 1. which co-act with the propeller D to cause the water to be thrown in sheets, or sprays, over and through the. dishes. which may be supported in the vessel A by lany suitable means. as, for instance, by the open-work tray, or basket, F. The vertical wall of the vessel is preferablyv provided. also, with a lower inwardly-struck circumferential bead 2, which is located some distance above the dislied bottom 3 of the vessel. Also, the vertical wall of the vessel is preferablyv provided with inwardlyinvention illus- Specification of Letters Patent. Patented JaIL 11, 1921.

struck circumferential beads 4 and 5, which are spaced somedistance apart and located some-distance above the reinforced upper edge 6 of the vertical wall.
l`he top, or cover, A', preferably cornprises an upwardlly dished sheet-metal member provided centrally with a handle ,and equipped at its circumference with a reinforcement 8 and a series of spring-arms, or supports, 9, which are adapted to engage the lower bead 4 when the top is in the closed position, and are adapted to engage the bead 5 when the top is lifted somewhat above the-'upper edge 6 of the vessel, so as to provide a ventilating space between the cover and the vessel.
The spider B comprises a hub 10, radial arms 11, and a flat ring 12, carried by said radial arms. One of the arms 11 has a depressed bearing, or support, 13, which carries a vertical pivot for one of the members of the actuating mechanism E; -and at one point the ring 12 has formed integrally therewith an upwardly-projecting lug, or support 14, which serves to carry the pivot of the actuating lever of the mechanism E. The hub 10 of the spider is provided with a perforation, through which extends a. gland-like bearing 15 for the shaft C. The member 15 has its lower end equipped with a flange 15 which is secured, by cap-screws 16, to the hub 10, against the lower surface of which the flange 15a bears. The sleeve, or bearing, 15, `entends through the hub 10 and through a central perforation in the bottom 3 of the vessel A, the upper end of the sleeve being externally threaded.
The upper end of the shaft C is journaled in a sleeve 17 which has an enlarged lower end, which is internally threaded and screwed on to the upper end of the sleeve 15, a washer, or gasket 18, being interposed between the lower end of the slee-ve 17 and the bottom 3 of the vessel A.
It will be understood that the perforate central portion of the bottom 3 of the vessel A is clamped between the hub of the spider and the lower end of the sleeve 17, a watertight joint being afforded. -The upper end of: the shaft C is fitted with a cap, or bearing,
19. which is rigidly secured to the/shaft and flange 19a which fits freely over the upper end of the sleeve 17. The upper end of the shaft C is slightly reduced and fits into an' The propeller-blade, or paddle, D, is
'equipped at its inner end with an attaching arm, or bracket, 22, which is fixedly secured to and depends from the bearing-cap 19, and which may be integrally formed therewith, if desired. rI`hus, the blade D will rotate with the shaft C, to which the paddle-supporting cap 19 is firmly secured.
The vertical corrugations 1 of the vessel A extend from the lower bead 2 approximately to the lower one 4 of the top beads. Thus, the vessel is well stiffened. The paddle D is disposed below the plane of the lower circumferential bead 2.
lThe mechanism E comprises a hand-lever 23 supported on a horizontal pivot 24 carried by the supporting lug 14 of the spider, the hand-lever being equipped at its lower end with a gear-segment 23a; a lever 25 journaled on a vertical pivot 26 carried by the supporting member 13 of the spider, the
outer end of the lever being equipped with a gear-segment 25a which engages the gearsegment 28a, and the inner end of the lever being equipped with a gear-segment 25"; and a pinion 27 secured on the shaft C and meshing with the gear-segment 25h.
rIhe gear-segments 23'L and 25L are covered by a guard 28, which depends from an extension of the stud 24 which forms the pivot for the lever 23.
In operation, the oscillation of the handlever 23 serves to oscillate the lever 25, the motion being communicated through the pinion 27 to the vertical propeller shaft C. The movement of the propeller D tends to create a centrifugal flow of the water which is contained in the lower portion of the vessel A, the water being forced upwardly over the lower circumferential bead 2 and along the inner sides of the vessel. The internal circumferential bead 2 and the vertical corrugations of the vessel cause the water to be thrown in a spray over the dishes contained in the basket F, it being noted that the bottom 29 of the basket is disposed slightly above the bead 2. the basket being provided with feet 29a, which are supported upon the peripheral portion of the bottom of the vessel. Any suitable means for draining the vessel (not shown) may be provided. Then the machine is not in use, the cover i' is left in the elevated position, with the spring-supports 9.engaging the upper bead 5, so that the vessel A will be thoroughly ventilated. It may be added that when the machine is in use, the lower circumferential bead, 2, will aid in causing some of the water to break inwardly and strike the lower sides, or lower edge-portions, of the dishes.
The machine described is simple and cheap in construction, easily operated, readily kept in sanitary condition, and highly effective in operation. The construction provides a water-tight connection between the bearing for the propeller-shaft C and the bottom of the sheet-metal vessel, and also provides for a water-tight bearing for the shaft C, it being noted that, in practice, the normal water level of the water used for washing or rinsing purposes will be below the upper end of the bearing-sleeve 17.
The advantages noted above are important. contributing as they do to the production of a machine which can be sold at a pop ular price and used in the household, as well as in restaurants. or the like, where dishes must be washed in large numbers:
The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible in view of the prior art.
TWhat I regard as new, and desire to secure by Letters Patent. is:
1. In a dish-washing machine, the combination of a sheet-metal vessel having a bottom wall provided with a perforation, a spider supporting the bottom of said vessel and having a perforate hub registering with the perforation of said vessel, a bearing sleeve extending through said perforations and having an elongated extension projecting a considerable distance above said bottom, a liquid tight joint being provided between said sleeve and the bottom of the vessel, a propeller shaft extending through said bearing-sleeve and projecting beyond the upper end thereof. means connected with the lower end of said shaft for actuating the same, a bearing-member secured to the upper end of said shaft and engaging the extension of said bearing-sleeve, and a waterpropelling blade supported by said lastnamed member.
