To all whom it may concern:

Be it known thatA I, GEORGE S. BLAKESLEE, a citizen of the United States, and a resident of Chicago, in the county of. Cook, State of Illinois, have invented certain new and useful Improvements in Dishwashing Machines, of which the following is a speci# iication, reference being had to the accompan ing drawings.

y invention relates to dish washing machines of the type in which the dishes are to be placed directly upon a conveyor upon which they are to rest while being carried through and past a shower or showers of water. It is one of the objects of my invention to provide a new and improved form of conveyor belt adapted to hold the dishes in proper position for being readily cleansed by the streams of Water forced upon them. It is another object of my invention to provide a new and improved form and arrangement of means for taking the dishes from the conveyor belt at the delivery end of the machine. It is another object of my invention to provide a new and improved form and arrangement of tank and enclosing means within which the cleansing and rinsing water is forced upon the dishes. It is another object of my invention to irnprove dish washing machines in sundry de-` tails hereinafter pointed out. The preferred means by which I have accomplished my several objects are illustrated in the drawings and are hereinafter specifically 'described. That which I believe to be new and desire to cover by this application is set forth in the claims.

In the drawings v Fig. 1 is a top or plan view of the preferred form of embodiment of my invention Fig. 2 is a side view of the machine shown in Fig. 1;

Fig. 3 is a longitudinal vertical section through' my machine, taken substantially on line 3-3 of Fig. 1; I

Fig. 11 is an outer face view of a modified form of cross-bar; and

Fig. 12 is an enlarged detail, being a cross-section taken on line 12-12 of Fig. 11,v but with the bar turned through 90 from the position shown in said Fig. 11.

Referring to Figs. l to l0, in which corresponding parts are indicated by the same reference characters,-

2O indicates a framework upon which is mounted a tank 21 divided by a partition 22 into compartments 23-24. The tank 21 comprises circular housings 25-26 at one side, the tops of which are in alinement with the top 27 of the tank. A partition 28 is p-rovided at one side of the tank 21 extending* from the top 27 to about the level at which the water stands in the tank, being provided with sliding doors 29-30 at one side. The side of the tank 21 adjacent to the partition 28 is provided with sliding doors 31-32 whereby access may be had from tlie side to the interiorvof the tank at either side of the partition 28 as may be desired.

Water is adapted to be delivered to the sections 23-24 of the tank by means of a line of piping 33 provided with suitable valves 34 for controlling the admission of water. A steam-pipe 35 equipped with suitable valves 36 is provided for admitting steam to the water in the tank, the steam beingv admitted to the water through-suitable nozzles 37. A drain pipe 38 is provided having a plurality of connections 39 with vthe floor of the tank, each of such connections beingi provided with a valve 40.

A shaft 41 extends longitudinally of the machine through the housings 25-26, being provided with paddle wheels 42-43 of any suitable type adapted upon the rotation of the shaft 41 in clockwise direction in Fig.

5 to throw water with considerable force laterally across the upper'porton of the tank 21, as is well understood in the art. The shaft 41 is driven throu h the medium of a drive wheel 44 preferabgl in the form of a pulley fixed upon a sha t 45 whlch 1s connected with the shaft 41 by means of a sprocket chain 46 running over sprocket wheels 47-48 mounted u on said shafts respectively. The drive w eel 44 is adapted to be driven from any suitable source of power. I

M improved conveyor is 1n the form of a belt comprising a plurality of chains 49 connected together by a vseries of cross-bars 50. The belt is supported at its ends by sprocket wheels 51 mounted upon transversely-extending shafts 52-5,3. The belt is further supported by means of channels 54--55 extending longitudinally of the'tank mounted upon transversely-extending bars 56, the ends of which are mounted 1n brackets 57 of any suitable type. The conveyor belt is driven, so as to carry its upper portion toward. the left in Fig. 1, by means of a sprocket wheel 58 mounted upon the outer end of the shaft 53,' the gear 58 being driven in turn by a sprocket chain 59 working upon a sprocket wheel 60 mounted upon a short shaft 61 which is connected by any suitable gearing with th shaft 41 Within a housing 62.

The cross-bars 50 of my improved conveyor are provided with a plurality of closely associated pegs 63-64 at intervals therealong, the egs 64 being shorter than the pegs 63. nly a limited number' of pegs 64 are employed in the construction shown, each peg 64' being solocated as to be surrounded by a series of longer pegs 63, thus providing pockets in the face of the conveyor adapted for holding cups in suitable position for the cleansing process. Other dishes such as plates, saucers, etc., are stood on edge between `adjacent pegs, as shown in Fig. 8.

Preferably a table 65 is employed at the end of the machine at which the dishes are fed thereto, such table having its top even with a fore-plate 66 provided with a plurality of -fingers 67 extending between the rows of pegs 63 of the conveyor belt. At the opposite end of the machine a deliveryplate 68 is employed having fingers 69 eX- tending between the`rows of pegs for receiving the dishes from the conveyor and sliding them' gently into position -upon a table l0 at the delivery end of the machine. The table 70 is preferably arranged'ona slight incline so as to Yprovide for draining the water from the dishes as they are slid into position thereon, being adapted to return t e water to'the tank 21'. Guards -71 are provided upon the table 70 for presage of water through the pipe.

venting the dishes from being ,pushed from the partition 22, such expedient serving to` increase the durabilit o the parts.

With the shaft 41 eing driven in clockwise direction in Fig. 5 and with the upper part of the conveyor being moved toward the left in F ig. 4, dishes are placed upon the conveyor between the pegs 63-64, being carried by the conveyor along the tank 21. As the dishes are carried past the paddle wheel 42, a quantity of water containing soap. or other cleaning agent is thrown by the paddle wheel upon the dishes, the water from the paddle wheel 42 being broken up by means of a screen 74. Curtains 75-76 of any suitable type are employed for preventing the water from splashin out of the section 23 of the tank. As t e dishes advance along the tank a uantity ofy rinse water is thrown upon the dishes by the paddle wheel 43, a screen 77 being provided for breaking up the water, and curtains 78-179 being provided for preventing splashing of the water out of the section 24. Before the dishes leave the delivery end of the conveyor, water is forced downward upon the dishes for a final cleansing from a perforated pipe 80 which extends across the tank along the top thereof, the water for this final cleansing being supplied through a pipe 81 from any suitable source, a valve 82 being provided for controllin the pasen the dishes arrive at the delivery plate 68 they are either removed by hand as they arrive or are permitted to pile up more or less upon the 'delivery plate and upon the table 70. y

While I have shown the cross-bars'() having smooth outer faces provided with pins or pegs 63-64 for furnishing the proper irregularities for supporting the dishes independently of each other in the desired lposition for suitable cleaning by the water thrown across the tank, it will be understood c that I do not wish to be restricted to this particular construction and arrangement, except as hereinafter specifically claimed.

What I claim as mv invention and desire to secure b vLetters Patent, is-

1. In a ish washing machine, the combination of a tank,an endless conveyor extending longitudinally of the tank and including means for supporting plates on edge thereon and providing pockets to receive cups and the like, and means for throwing water upon articles carried by the conveyor.
