1,398,022. Specification of Letter" Patent. flfite-ig ij i Application Zllffd October (5, 1920.
To a-ZZ whom it may concern: 5" Be it known that I, Mnnn ii. .1101 .1
citizen of the United States, and a resident of roolclyn, Kings county, and State of Jew York, have invented certain new and useful improvements in Dishll ashing hiechines, of which the following is a specification.
The objects of my present invention are to provide a simple and relatively inexpensive apparatus for washing dishes and other culinary utensils, which will be thoroughly ellicient in its operation.
In a preferred embodiment of the invention, the dishes or other articles are supported in a rotating racl; or basket and are successively subjected, in the rotation of the rack, to a column of cleansing fiuidpio jected upwardly; over the same, by a r0 peller supported eecentrically beneath the rotating rack.
The invention involves certain other novel features of construction, combinations and relations of parts all as will be more fully disclosed in the following specification.
In the drawing accompanying and forming a part of this specification, l have illustrated two different embodiments of the invention, but wish it understood that further modifications may be made Without departing from the true spirit and scope of the invention as hereinafter defined and claimed.
In the drawing referred to, Figure 1 is a vertical sectional view of the apparatus.
Fig. 2 is a fragmentary plan and part sectioncl view.
ig. 3 is a broken vertical sectional view of a modified form, and
Figs. stand 5 are broken plan and perspective views of the rack construction.
The apparatus comprises a casing or container 5 having?1 a close-fitting removable cover 6 and wit in which there is suitably journaled a basket or plate rack 7.
In the present disclosure this basket is shown as supported by a shaft 8, said shaft in the first form illustrated, Figs. 1 and 2, being supported at its lower end in a step bearing 9 and engaged at its upper end in a bearing 10 carried by the brace 11 extending radially inward from one side of the casing.
In the second form of theinvention illustrated, (Figs; 3 and s) the shaft is wholly or the small 1 .tfS, Jo
trev' l3 having a central hub ll it it i: removably engaged over the upper e -d of the supporting shaft 8.
propeller is conveniently driven by an elec-' tric motor, such as l have indicated at 16, it being shown as directly engaged on the motor shaft 17 which extends through a suitable st-ufiing box 18. I have shown this motor as detachably connected at 19 with the pedestal 20 which forms the base or support for the machine. This relieves the casing of the weight of the motor and enables the removal of the motor, without disturbing other parts of the machine. To facilitate such removal, the motor shaft. may have a detachable coupling therein, such as I have indicated at 21.
The carrier is rotated in the first form of the invention shown, by directly gearing the same to the motor shaft through gear'22 and pinzon 23, the first being secured on the carrier shaft 8, and the latter on the motor shaft 17. This gearing is so proportioned and arraiuted as to produce a relatively slow rotation of the carrier and a relatively rapid rotation of the propeller, the speed of the latter being suiiicient to drive a forceful column of the cleansing liquid up over the dishes, etc, passing; thereovcr.
1n the moelfied form of the invention shown in and i, the rotation. of the carrier is etl'ected from the motor shaft as before, but in this instance, by utilizing the column of water or other cleansing liquid as the connecting; medium, the carrier in this form having a series of inclined radially arranged, puddle blades 94 which receive the impact of the Water column and convert the carrier into what is in effect slow motion turbine.
These blades are shown as widened. toward.
their outer ends to increase their effective as paddle blades and in addition to such casing,
function, the serve as rack bars for supporting the plates in inclined relation, it be mg seen that in placing the plates between these bars, they will naturally assume the de sired inclined relation.
In the modified construction, I have also shown the propeller as operating in or above a well or depression 26 provided in the bottom of the casing. This enables the propeller to throw a full column with only a relatively small supply of water in the casmg.
preferably stacked in the lower tray in inclined relation, as indicated, and cups, glassesfsilverware and the like are placed also preferabl in inverted relation on the upper tray. 1* or a cleansing fluid, hot soapy water is usually sufiicient and when a sufficient amount of this has been placed in the the motor is set into operation to drive the propeller and from that the rotary carrier. As the carrier rotates, successive sections of the dishes, etc, are brought into the direct range of the column projected upwardly by the propeller and hence all articles are in effect individually treated to the cleansing action of the column of hot water. This action may be repeated as many times as thought necessary for simply continuing the apparatus in operation.
lVhatI claim is:
1. Dish washing apparatus comprising a casing, adish carrier rotatably supported In using the apparatus, the dishes are therein on a substantially vertical axis, a propeller supported at a fixed point beneath the carrier on a substantially vertical axis and eccentric to the axis of the carrier, means for (iperating said propeller and means by which thecarrier is rotated by liquid from the propeller to thereby bring articles stacked on the carrier successively into the range of direct influence of the propeller.
2. The combination of claim 1, wherein the driving means for the carrier includes inclined blades on the carrier forming a rack for the dishes and operating as paddle blades when in the range of the stream projected by the propeller.
3. The combination of claim 1, wherein the casing is provided with a well in the bottom thereof and over which the propeller is located. 7
4. Dish washingapparatus comprising a casing, a dish carrier rotatably supported therein on a substantially vertical axis and provided with inclined blades forming a rack for supporting dishes in inclined relation and means for projecting a stream of water, from a fixed point beneath the carrier and at one side of the axis of the carrier, up- Wardly against the inclined blades and the plates supported thereby, so as to thereby rotate the carrier.
In witness whereof I have hereunto set my hand this 2nd day of October, 1920.
