JOHNJ. OWENS, 0F BLACCKSBURG, VIRGINIA DISHWASHING- MACHINE.

My inventionv relates to dish washing machines, and its principal object is to provide a dish washingmachine embodying a fixed tank and reciprocal dish carrying receptacles which are guided in a tru'e vertical direction, and thereby obviate breaking of the dishes or other fragile articles being washed, incident to lateral movement.

Still another object of the invention is to provide a dish washing machine of this character, wherein the dish carrying receptacles are reciprocated by means of leccentrically mounted flexible elements depending from driven elements, the dish carrying receptacles being positively guided in a verticaldirection against the normal tendency of the flexible elements to move in an angular direction, due to the eccentric connection of the latter with the driven elements.

The invention also contemplates a washing machine embodying a washing tank divided into a plurality of compartments, into each of which a heating coil is arranged, the latu ter being located in an out of the way posiall tion where they willY not be engaged by the reciprocal dish carrying receptacle.

With the preceding and other objects and advantages in mind, the invention consists of the novel combination of elements, constructions and arrangements of parts, and operations to be hereinafter specifically referred to, claimed'and illustrated in the accompanying drawings, wherein,

Fig. 1 is a front elevation of a dish washing machine constructed in accordance with my invention. f

Fig. 2 is a side elevation of the same.

Fig. 5 is a top p an view of the dish w'aslnV ingmachine tank.

Fig. 6 is a vertical sectional view of the same adjacent a table, the latter being shown in broken lines'. r

Fig-8 is a top plan view of one of the dish carrying receptacle guides.

Fig. 9 is a side, levation of the same.

Fig. 10 is an elevation of the removables bottom of the guide.

Referring in detail to the drawings, wherein correspondingnharacters of reference denote correspon g parts throughout 1925. Serial No. 42,510.

the several views, the letter a designates a tank divided into compartments by means of a vertical centrally arranged transverse partition b. @verlyingthe upper edge of the 6 tank a and extending beyond the side walls thereof'is a plate c provided with a pair of relatively large rectangular openings al, the latter being disposed at the lvertical center of each of thev compartments as shown in Figure 6. As shown in/Figure 7 the pla-te c rests upon outwardly extending flanges e formed on the upperedge of the side walls of the tank a, and is detachably secured to this flange by removable fastenings f. A marginal depending flange g is formed with the outer edge of the plate c.

For the purpose of heating water contained in the compartments of the tank a, a vertically arranged heating coil h 1s ar'- ranged in each of the compartments, and one end of which is in communication with a heating medium conducting pipe i, and the other end has communication witlran outlet pipe j. l

Arranged below each of the compartments of the tank a is a valved controlled water supply pi e la, which extends through the bottom wa l of the tank. Drain pipes Z pass through the bottom wall of the tank and are ofsuch height asto extend to a point adjacent the upper end of the compartments Y where they will drain the upper surface of water contained in the compartments, and thereby retain the water in a relatively clean 90 state at all times. a n

A pulley driven shaft m is mounted in bearings n, fixed tothe ceiling or other horlzontal support o. A disk p 1s fixed to each end of the pulley driven shaft m and 1s 95 disposed in vertical alinement withthe center of each opening d of the plate c. Eccentrically mounted pitmen or hooks Jg are carried by each of the disks p, and detachably Vtractile springs 'wf depend from the lower ends of the chains or flexible elements t, the latter carrying hooks m which engage reticulated dish carrying receptacles or frames z, il@ movable in the compartments of the tank a.

I have found lfrom experience that the dish carrying receptacles leXibly connected to the disks p will swing laterally, due to the slipping of the dishes in the receptacle and due to the Jfact that the chains move oli their vertical centerA (regardless of how close the rollers may be arranged together). ln order to overcome this objection, and `,thereby prevent the dishes from becoming broken, I provide a guide shown in Figures 8 to l0 `for each compartment. This guide comprises a rectangular Lshaped in cross section rim a to the vertical leg ov which a plurality of spaced vertical guide bars b is attached. A rectangular latticed bottom c is carried by the lower ends of these guide rods b.

" lt will be further observed that the walls of the compartments'may be readily reached for the purpose of removing grease or other foreign matter, by reason of the guide frames being removably supported in the counter-sinks c asA aforementioned. Furthermore, the heating coils can be conveniently reached by reason of the plate o beingdetachably supported on the tank.

claims. v

l Matese While ll have illustrated anddescribed one embodiment of the invention, lt wish to yemphasize that I' do not limit myselil. tb

the exact construction set yforth, but that ll may make alterations and modifications therein, and such alterations and modifications are' only governed by the appended -What ll claim is:- v

1. A dish washing machine comprising a tank for containing water, a plate 4secured to the upper edge of the tank and provided with an opening and a 'counter-sink surrounding the opening, a dish carrying receptacle cage arranged in the tank, including a rim which rests in the counter-sink, vertical guide' bars depending from said rim and having a :toraminous bottom secured to said bars, a reciprocable dish carrying receptacle arranged in the cage and contacting with the latter and means for reciprocating said receptacle in said cage.

2. A dish washing machine comprising a tank, a uide cage removably secured therein, a dish holding receptacle reciprocable vertically in said guide cage, a crank rotatably mounted centrally above said cage, y

a cable connecting4 said receptacle to said crank and means engaging said cable between said crank and receptacle to maintain that part of said cable between said means' and receptacle constantly -vertical durin the vertical reciprocation ffsaid.' cable an ref ceptacle by rotation ofsaidfcrank.
