' DISHWASHER.

i Application mea December 1,5, 1927. serial No. 246,228.

that will effeetually. wash a large number of vessels at the same time, and one that is simple in form and construction, economical te tical ap lication.

It is a so an object of the invention to provide a novel form of holder for each individual-vessel, whereby the vessel willbe held against movementl while being washed and yet 'not clamped or otherwise fastened in position, and so formed Aand constructed that a vessel may be quickly positioned therein or removed therefrom.

It is still another object of the invention `to provide an efficient rack for the several I holders and a suitable tubadapted to be used Y in conjunction with the rack.'`

I fvesse igure 6 is an enlarged detail esection vthrough the shaft support.

In the drawing Y Figure" 1 is a sldeelevation of a 'double washer embodying my invention, part broken `away and-partly in section. A

Flgure 2 is a detail plan view on 2-12, Figure 1.

Figure 3 is a detail plan view on line 3--3 0f Figure 1. f Y Figure 4 is a section on line 4 4, Figure 1. Figure 5 is a perspective view of one of the F holders and a portion of the rack.

Figure 7 is a perspective illustration of a portion of the upper end of one of the retainlng bars and the' means for securing thesame to the rack. s Y Figure 8 is aside view @of a portion of the lower end of one of the retaining bars and its As u means.

femng now more particularly to the drawing, I show at 1 a tub lined with a noncorrosive metal 2 and supported 'on legs` 3. In the center of the bottom of the tub is formed an opening 4, and the tub lining is lformedinto an upstanding cone over this opening as shown at, 5 and fitted with a suita le bearing at its upperend as indicated at 6 f A cover mounted on the tub as shown at `dicated, edge of the yoke vat 36.-

Arranged below the tub 1 is a cross-bar 8, and mounted on this bar isa motor 9 operating a drive shaft 10 mounted in bearings 1l and fitted with a worm gear 12. Meshing with gear 12 is a gear 13 on shaft 14, the latter passing upwardly through bar 8 and fitted with finger l15. The finger 15 is provided with ai cam surface or edge 16 on the side directed forwardly of its path of travel, the latter being indicated by the arrow 17. K

At 18 is shown a rack operating shaft mounted in parallel relation to shaft 14 and spaced a distance therefrom and in axial alignment' with the bearing. This shaft passes downwardly through bar 8 and has an annular collar 19 mounted thereon seated upon balls 20 in a cup 21 mounted on the upper side of bar 8 as shown. Mounted on shaft 18 to rotate therewith and in the plane of the finger 15 is a yoke 22. This yoke is so arranged that when the finger 15 is rot-ated from the position shown in solid lines in Figure 2 the-tip ner edge o the-yoke on one side and swing itfintothe position shown in dotted lines at.

23.v When this point is reached the shoulder of the finger, as 24, engages thel inner edge of the opposite side of the yoke so that the cam ,surface V16 will swing the yoke into the position shown in dotted lines at 25. In this ofthe finger will engage the inposition the shoulder 24 engages `the first inand reverses its movement. volving of the finger 15 imparts an oscillatory movement to the shaft 18.

of the shaft 18 is squared as indicated at 26.

In this manner the continued re- The upper end The rack comprises a top member 27 seated upon the squared upper end of shaft 18so as to rotate therewith, and provided with a' handle 28. This member -27 is preferably hexagonal in shape and has a depending wire 29 mounted upon each corner, eachwire having a vertical portion and an outwardly directed horizontal portionA several-times repeated to form a stepped arrangement. The

correspodning corners of the several stepped wires are joined by horizontal wires as.30 and 31 wherebyfto form arigid one-,piece rack. The lower end of each wire 29 is extended outwardly a distance and then turned upwardly as at 32 to engage the Socket 33 in the lower end ofa. wooden bar 34. This bar 34 parallelsthe angle of. the adjacent wire29 andj'is supported at its upper end by a, wire loop 35 swingably mounted on the rack asv y Each of the steps in the rack above del scribed, forms a seat `for a vessel holding basket. The basket comprises a Wire 37 arranged parallel with a wire 30 ,and having its two ends bent into arallel loops as 38 and 39 and terminating 1n small loops 40-41 engaging the wire 30. A wire 42 is mounted on the loops 38-39 and extends a distance therebeyond to engage the adjacent wires 29 to function as stops and prevent the basket from swinging inwardly of the rack. In plan View the wire 37 is angularly arranged relative to the supporting wire 30 thereby making the end loop 38 smaller than loop 39, and parallelly arranged relative to loop38 are a number f spaced loops 43, 44, 45, 46, 47. Connecting the last loop 47 with the loop 39 at the larger end of the basket are wires as 48. By means of thisvconstruction a goblet or glass of any size or form may be placed in av basket and securely held there through the engagement of its foot piece with the trans# verse loops 43-47. A tumbler, or glass with'- out a foot or stem, is held in the basket by the Wood bars 34.

Assuming that the device has been constructed as above described and water placed in the tub 1, the rack is filled with glasses in in Whatever form or size they come to hand,

a basket of suitable size being found for every glass. The glasses are placed in the several baskets with their stem ends directed toward the smaller end of the baskets so that theiropen ends ma all be pointed toward the larger ends of the baskets. The rack is now placed in the tub 1 and on the shaft 18, thel cover is closed and thev motor started. The reciprocating movement of the shaft is of course im arted to the rack and the said rack and t e glasses thereon areswung back and forth in the water in such a manner as to thoroughly cleanse andwash each one.

TheA means for securing the oscillatory novement 1s lmportant because the] action of the finger 15 is such that one movement 45 (into position 23) is more rapid than any other movement of the yoke and this is effective in securing the fullest cleansing effect of the agitated water.

The loops 40-41 of each basket are prefer- 50 ably formed in such a manner that the basket can be unhooked from the wire 30, and of course this connection permits the basket to be swung into and out of position when desired in placing or removing glasses. y

It is to be understood, of course, that while I have herein shown and described but one specific embodiment of the invention, changes `in form, construction, and method of assembly and operation may be made Within the scope of the appended claims. v

I claim: v

1. In a dish washer, a rack, a plurality of baskets without end Walls mounted thereon, and means mounted on the rack adjacent the ends of the baskets to prevent ejection or dishes from the baskets. y A

. 2. A basket comprising awirehaving both l ends bent into parallel loops terminating in means for mounting the same on'a; rack anda l70 straight intermediate portion, a! 'second jwire disposed parallel to the straight intermedi# ate portion of said first wireandfconnecting y the loops, a plurality of wires connecting said second wire and the straight intermediate portion of said first Wire and `formed into loops arranged in spaced and parallel relation to the frrst loops, andv a pluralityy off wires disposed parallel tothe secondj wire and connecting one of the first p' mentioned 8o end loops with one of the last'v mentioned loops.
