DISH WASHING MACHINE.
APPLICATION FILED APR. 9. 1919.
1,39%3 Patented Sept. 6, 1921.
MNlTED STATES PATENT QFHCE@ FRANK E. WOLCOTT, 0F "HARTFORD, CONNECTICUT.
DXSHFWSHNG MACHNE To all whom t may concern:
Be it known that I, FRANK E. Woncofrr, a citizen of the United States, and a resident of Hartford in the county of Hartford and State of onnecticut, have invented a new and improved Dish-Washing Machine, of which the following is a specication.
My invention relates to the class of devices employed for cleansing dishes, and an object of my invention, among others, is to provide a. device of this class that shall be extremely durable, simple in construction and eii'ective in operation.
One form of device embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which Figure 1 is a ,view in vertical central section through a dish washing machine embodying my invention. Fig. 2 is a view in horizontal section on plane denoted by dotted line 2-2 of Fig. 1.
ln the accompanying drawings thev numeral 5 indicates a receptacle of any suitable form'and material supported upon legs 6 and having a cover 7 attached in any desired manner and rovided with means to receive a basket 8 1n which the dishes are placed, this basket being preferably of wire mesh and being supported in any suitable manner. A bearing sleeve 9 projects upwardly from the bottom of the receptacle, in the structure herein sho-wn this sleeve projecting through an opening in said bottom and being secured in place in any desired manner. A shaft 10 projects upwardly through `this sleeve, the latter having any suitable means for sup orting the shaft for rotation therein, and t e shaft may be connected in any suitable manner with a motor 11 as ameans for rotating it.
also provide a hub'lQ secured to the upper end ofthe shaft 10 and having its side walls surrounding the sleeve 9 and extending to a point near the bottom of the receptacle. ln the structure herein shown this hub is in the form of a housing completely inclosing the bearing, but l do not necessarily limit my device to such structure, as its main pur- Specication of Letters Patent.
rammen sept., e, taai. 191e. serial no. team. l'
pose is a support for blades 13 that project from the hub and that are preferably inclmed to a vertical plane, in the structure herein shown two of these blades being employed.
it ring 14 is secured to the blades lin any deslredmanner, this ring providing weight for the structure and thereby serving to balance it to a greater or lesser extent. ln the operation of the device the dishes to be cleansed are placed within the lbasket 8 and a proper cleansing liquid is placed in the bottom of the receptacle but not enough tol overflow the top of the sleeve 9. 'lhe blades 13 being now rapidly revolved, the liquid w1ll be thrown upwardly into contact with the dishes in the basket 8.
Centrifugal action caused by the rotation of the blades 13 tends to pile up a wall of water about the inner wall of the receptacle and in order to counteract thisleliect 'and break down this wave and throw the water upward thereby increasing the amount and force of the water -projected against the dishes within the basket, auxiliary blades 15 are mounted upon the ring 14. rlhese blades extend from close to the outer wall of the receptacle but a short distance inward beyond the ring and they are preferably disposed so as to extend tangent to a circle of different diameter than the circle to which the blades 13 are tangent, as shown in Fig.
2, whereby their action will cause currentsv which will interfere with'the currents produced by the blades 13 and enable the water to be more directly thrown up against the dishes in the basket above.
ln order to prevent a swirling motion of the liquid within the receptacle l provide a number of baffle plates 16, in such number as may be desired, these plates being disposed edgewise upon the bottom of the receptacle and underneath the plane of-rotation of the lower edges of the blades 13 and the ring 1t.
My improved device herein described embodies means whereby a shaftmay be readily mounted in the receptacle to extend upics patent statutes, oiples of operation of my invention, together with the device which l now consider/to represent the best embodiment thereof; but l desire to have it understood that the device shown is only illustrative, and that the invention maf,7 be carried out by means.
I claiml. A dish washing machine comprising a closed receptacle, an openwork basket removably supported within the receptacle, a motor shaft passing through the bottom of the receptacle, a hollow hubfastened to themotor shaft within the receptacle, propeller blades extending on diarnetrieallj,7 opposite sides from said hub outward to close proximity to the wall of the receptacle, a ring connecting said blades intermediate the hub and the wall of the receptacle, and propeller blades extending inward from close proximity to the wall of the receptacle but partway toward the hub and fastened to said ring intermediate the iirst mentioned blades, both sets of said blades being in substantially the same horizontal plane and having have described the prin' othermotor shaft passing substantially the same pitch for throwing water upward from the lower part of the reeeptacle through the basket..
2. A dish washing maehi'ne comprising a closed receptacle, an openwork basket removably supported within the receptacle, a through the bottom of the receptacle, a hollow hub fastened tothe motor shaft within the receptacle, propeller bladesy extending on diametrioally opposite sides from said hub outward to elose proximity to the wall of, the receptacle, a ring eonnecting said blades intermediate the hub andthe wall of the receptacle, propeller blades extending inward from elose proximityI to the wall of the receptacle but partway toward the hub and fastened to said ring intermediate ythe first mentioned blades, both sets of said blades being in substantially the same horizontal plane and having substantially the same pitch for throwing water upward from (the. lower lpart of the receptacle through the basket, but extending tangent to concentric circles of different diameters. v
