My invention is concerned with dish washing machines of the type in which the dishes, etc., are carried through the machine on the upper runof an endless carrier, such, formas is shown in my application No. 317,176, filed November 5,1928, and my present invention is designed to produce such a device, in which knives, forks, spoons, etc., may be readily carried through it, and, when desired, be discharged into a special receptacle designed to receive them, instead of being discharged on the table on which cups, saucers, plates, etc., are discharged.
To this end, it consists in a novel structure and combination of elements,-all of which will be hereinafter fully described, and the novel features and combinations'particularly pointed out in the claims.
To illustrate my invention, Iannex hereto two sheets of drawings, in which the same reference characters are used 7 to designate identical parts inall thefigures, of which,-.
Fig. 1 is mainly a central longitudinal, vertical section through a dish-washer embodying my invention v Fig. 2 is a top plan view of the same as seen in section on the line 2-2 of Fig.1; and
Figs. 3 and 4: are enlarged details in side elevation, as seen from the lines 34 of Fig. 2.
In'machines of this type, which are usually adapted to be placed upon the bottom of a sink 10, I preferably employ the skeleton framework composed of two side pieces 11 having the legs 12 supporting the machine,
and provided with the receiving and dis charge tables 13 and 1a, which preferably con sist of the horizontal web with the downwardly projecting] triangular portion 15 at 7 each end,-'which triangular portions are con nected by the horizontal bars 16, which are secured on the ends of abutments provided thereforon the frame by the screws 17 These bars 16' serve asa partial means for 'securingthe two sections together, their action being supplemented'by that of the pair of shafts Band 19 journaled in suitable bearings in 5 the side frames and having the sprocket wheels 20 and 21 secured thereon just inside of the side frames. These sprocket wheels 20 and 21 co-operate with theends of 1929. Serial No. 358,916.
the transverse rods 22, which-are connected attheir ends bythe links 23*which form a pairof chains, with the ends of the rods constituting the pivotal connections therefor. As these rods are separated some little'distance and it is desired to carry such articles as knives, forks and spoons on the surface of the carrier thus formed, the rods'23 are further connected, as by the wiresl24c, which eX- tend entirely a-round the carrier and are held inplace by being given a turn around each of the rods, the turns or "coils being placed in the annular grooves 25 formed in the rods for this purpose. Suitable power, such as that ofan electric motor 26, is applied to the carrier through thernedium of a worm 27 on the armature shaft meshing with a worm gear 28 onthe horizontal shaft 29 having a worm 30 on its other end meshing with a worm gear 31 secured on the shaftlSi l The carrier thus far described is prefer-v ably removable from the sink, and, to furnish the necessary hot suds for'fwashing the dishes, I provide the perforated pipes 32 and .33 extending in-use transversely across the carrier above and below the upper run, so that water delivered from the hot-water fauact 34 through the piping indicated in dotted linesin Fig. 1 will be sprayed upward from the pipe32 on the bottom of the dishes and downward from the pipe 33 on the top as they move slowly between the pipes by the movement of the carrier. The pipes 32' and 33 are provided with the soap boxes 35 and are preferably pivoted to the connecting pipes at 36 so that they can be swung to one side and paral- :lel to the rear wall of the sink 10 when the washing-machine is not in use. Similar spray pipes 37 and 38 are provided at the other end of the machine andconnected to the faucet 34-, and spray thedishes with clear I rinse water before they leavethe machine.
The structure thus far described is that shown in my aforesaid application Serial filed November 5, 1928. I
Where a considerable number of knivespj forks, spoons,"etc.,' are placed on the carrier to be washed, it isdesirable .to provide means whereby th eyican bev discharged into a receptacle automatically, and for this purpose I secure on the cross piece 16 at the in washing plates, saucers, cups,
discharge end the trough 39, which is preferably composed of sheet metal, and the body portion of which is preferably semicylindrical in its outline.
At the edge above the cross piece 16, I preferably bend over the portion 40 so that it comes substantially in contact with the carrier as it passes beneath it. Obviously, knives, forks, spoons, etc., whic of the carrier, will drop off of the carrier on to the inclined portion 40, and thence fall into the receptacle 39, whence they can be removed at leisure. V
I have found that sometimes portions of the forks. and spoons, especially, project through the interstices between the rods 22, and make trouble in discharging. To prevent this possibility, I provide the cam plate 41, which is preferably composed of sheet metal and is of the design seen in Figs. 1 and 2, where it will be seen that the downwardly-turned ends of the ears 42 are secured by screws 43 to the inner wall of the side pieces or frames 11.
1 The main body of the plate 41 is rectangular in its outline, and slants upwardly, as seen in Fig. 1, until it is directly beneath the carrier, where it is then curved to form the portion 44, which extends as a portion of a cylinder directly beneath thecarrier. If any portion of the cutlery projects through the belt, as it reaches and passes over the plate 41, itwill be cammed upward and outward, so that there is no possibility of its failing to drop ofi of thecarrier when it reaches the portion 40.
When the apparatus is thus used for wash ing knives, forks, spoons, etc, it is necessary that a considerable space exist between the discharge table 14 and the nearest portion of the carrier that is in the same horizontal plane; but when the apparatus is to be used etc, such space is objectionable, as it is desired that the articles thus being washed should pass automatically from the belt on to the table- 14. To bridge this necessary gap at such times, I employ the bridge plate 45, which preferably consists of sheet metal, and has the cars 46 struck up from the ends of the plate in position to rest on the upper egdes of the side frames 11, as clearly shown in Figs. 2 and "3', The plate 1s supported-by the wire bail 47 which has its inwardly turned ends 48 extending through suitable apertures provided in the bracketsl-S at that end. The outer edge 49 of the bridge plate 45 is curved about and securedto the body of the bail 47 in the manner clearly shown in Figs. 3 and 4. lVhen the bridge plate 45 is in use, it occupies the position shown best in Figs. 2 and r 3, and when not in use, it is turnedback to the position shown in Fig. 4, where the knives, forks, etc., are free to drop down into the receptacle 39. The table 14 preferably hare laid lengthwise "the following claims except as may be necessitated by the state of the prior art.
What I claim as new, and desire to secure by Letters Patent ofthe United States, is:
1. In a dish-washing machine, the combination with a horizontally-movable skeleton carrier consisting of .a pair of endless chains mounted on wheels and'conneoted by parallel transverse rods in turn connected by longitudinal wires, of means for rotating said wheels, and a cam plate beneath the same extending; between, the wheels over which the cutlery isdischarged, and insubstantial contact with the rods; at thedis'charge point.
