BEDGE HARVEY AND ADOLPH- 1. WASHLAXE, OF DETROIT,

DISHWABHING IACHIIIN'IE.v l e .Application nled February. 28, 1993. Serial No. 629,596.

This invention relates to dish washing machines and the object of the invention is to provide a machine for washin dishes in which hot or cold water may used and which isadapted to be connected to the usual public water supply system,v Another object of theiinveiition is to provide a ma-l chine for Washing dishes' comprisin aspray nozzle designed to increase thejve ocity of water at the point' of discharge therefrom, a

tub being provided for the dishes into which the' spray nozzle is adapted to discharge'. Another object of the invention lis to provide a dish washing' machine having a spray to either side thereof. A further object'of the invention is to provide a dish washing machine comprising a tub having a wire basket rotatably mounted therein and a l .35 l n n Y drawings in which-- `the tub. The-tub 1 is also s ray nozzle `operable from the exterior of t e tub to direct water. to any pointon the interior thereof, the dish rack beig manually rotatable from the exterior of the tub.

vThese objects and'the several novel features of the invention are hereinafter more ully described and claimed and the preferred' form of construction b which these objects are attained is shown in the accompanying Fi 1 is a pian view ofi machine embodying our invention partly l broken away to show the construction.

Fig. 2 is a section ing machine.

Fig. 3 is a section through the spraynozzle and connections therefor.

The device comprises a tub 1 of cylindrical form as'sliown in Figs. 1 and 2 and is through the dish wash- `provided with a cove'r 2 resting on a bead 3 rolled into the upper edgle of the tub. The cover 2`is provided\wit 'an 'opening 4 in which a pane of glass' 5 is secured providing a window through which the interior of the' m'achine may be seen. This cover 2 is provided with a pair of handles 6 by which the cover may be removed from or replaced in provided with a pair ofhandles 7 and a pair of sup orting feet 8 shown more particularly inlig. 2.

dish washing discharge A tubular member 9 is Secured in the bottom ofthe tub to providea waterproof joint and extends upwardly into the center of the tub and a shaft 10 is rotatably mounted in the said tubular member 9, A ratchet 11 is vsecured to the end of the shaft 10 beneath y,the tuband an operating arm 12 is rotatably mounted on the shait 1() between the ratchet 11 and bottom of the tub as shown more particularly in Fig. 2. The end `of the arm 12- is bent,` downwardly at 13 as shown in Fig. 2 to provide a portion 14 which extends" beneath the rim l5 about the bottom of the tub .anda handle 16 for moving the arm 12 is secured to the portion 14 exteriorly of the tub las shown in Fig. l. A dog 17 is pivotallymounted on the arm 12 and a coiled spring 18 is provided holding the dog 17 in engagement with the teeth of the ratchetA 11. A tubular member 19 is secured to the shaft'l() by a pin 2() and this tubular member 19 extends about the tubularmember 9 and is provided with an a rtured Han' e 21 to which a wire basket 22 isgsecured. T e wire basket 22is shaped so "a quantity of dishes may be placed therein and the basket is rotatable bv vmovement of the arm 12 as `will be readil'y understood. An opening 23 is cut into the side' of the tub and a member 24 is secured thereover by the rivets' 25. This member-24 at the lower end extends on a level with the bottom of the tub and is provided with an opening 26 and a trough 27- is formed through which water may be discharged from the tub. The member 24 is provided with an ope in the side thereof in which a ball 28 is adapted to fit and a socket 29 is secured to the member 24 28 and is provided with a nozzle 31 on the` discharge end thereofhav'ingV conical shaped A apertures 32. (The pi 30 is oo nnected to. a T union 33 and a slirt tube 34 is threaded into the T union, a flexible conduit 35 being secured to the tube 3 4 b the clamp 36. The end of this flexible tu 35 is provided with a threaded connection 37 which may be attached to a hot or cold water faucet. Asolid rod 38 is threaded into the T union 33 and a ball 39 is secured to the end of the rod K38 and provides `a l iandle by means of which the spra nozzlemay be turned in different directions throughv the socket 29 and ball 28. Y In operation the dishes to be, washed 'am ios placed in the basket 22 and the device is pov are rotated and by means of the handle 39 i andthe ball and socket connectionthe water 10.

maybe ldirected on the different dishesin .the basket 22 as they passithe spray nozzle the dishes being exposed to view through the .window 5. By providing the conical apertures 32 for the spray nozzle`the velocity of the water passing therethrough is increased to considerable extent and the impact of the water on the surface of the dishes is of s uiii- .cient force to readily cleanse all foreign matter therefrom even when the device is the dog 17 and ratchet 11 the basket is turned l 3.In a dish washing machine, a tub, a roconnected to the cold water faucet. To con'- tinuously turn the basket the handle 16 is oscillatedthrough an'arc and by means of upon each clockwise motion of the arm and by grasping thehandle 39 at lthe same time Y the dishes may be readily seen through the window 5' so that the water may be directed to any dish or ortion of a dish desired,

and by means o the operating ar'm 12. the

basket may be sto ped at any point to allow any particular di to be held under the influence fof"- the spray nozzle. `When the dishes have been washed the member 37 mayA be connected to the hot water faucet to allow the dishes to be scaldedbefore being removed from the machine and dried. By

slottingthe upperend of the shaft 10 to receive they pin 2Q the basket 22 may be re.- moved together `with the tubular member 19 'to which 1t is attachedand the basket may be set on the sink to allow the dishes therein to drain dry or to allow 'drying by hand. As the water passes from the tub through the opening 26 as fast as it enters the tub through thenozzle .31 the cover may be removed to allow the dishes to drain dry within the tub after the water supply has been disconnected..

From the foregoing description it becomes evident that the device is very simple and efficient in operation, will not easily get out of order, is composed of few parts and is of consequent low manufacturing cost and provides a device whichaccomplishes the objects described.

andleA 16 through an arc` the wire basket and dishes Having thus .fully described our invention,

for dishes therein adapted to be turned, the

vertical Wall of the tub having an offset por,- tion terminating short ofthe bottom thereof providing an outlet, and a spray nozzle rotatably. mounted in the said offset portion of the vertical` Wall and terminating practically at the l.peripheryv1` of the tub.

2. In a washing machine, a cylindrical tub, a basket for dishes rotatably mounted therein, the vertical wall of. the said tub hav-N ing an offset portionproviding a recess, a spray nozzle, a ball and socket support for the nozzle in the said oii'set Wall, the nozzle terminating adjacent the ath of movement of the, periphery of the asket and dishes therein, a conduit for supplying water to the v nozzleand means providing for a continuous discharge of liquid from the said tub.

tatable basket therein, the wall of the said tub being .offset at one side to a height above the basket, a spray `nozzle mounted in the oiset Wall adapted to discharge fluid over and' through the said basket, the said oiset port-.ion terminating short `of the bottom of the tub providing a discharge aperture, and

atrough extending outwardly from the said discharge aperture through which fluid may be discharged from the tub.

4. In a dish washing machine, a tub having a Vertical wall provided with an aperture at one side, a member adapted to be secured over the aperture providing a recess beyond the periphery of the tub, said member having a bottom portlon coextensive 'with the bottom of the tub and a substantiallyv verticalwall terminatingshort of the bottom of the inember providing an aperture for egress of iiuid from the tub, a spray nozfcation.
