To all whom 'it may concern.'
Be it known that we,.HARRY T. Gross and JAMES VVAnEs BRYCE, citizens of the United States, and residents, respectively, of Rutherford, in the county of Bergen and State of New Jersey, and of Bloomfield, Vin
Essex' county and State of New Jersey,.
United States of America, have invented certain new and useful Improvements in Dish-Washing Machines, of which the following is aV specification.
Our invention relates to improvements in dish-washing machines, and its object is to provide a simple and inexpensive apparatus for this purpose. and to improve upon such devices as have heretofore been known.
We will describe our invention in the following specification and point out the novel features thereof in the appended claims,
Referring to the drawings, Figure 1 1 s a side elevation of a dish-washing machine made according to our invention. Fig. 2 1s a sectional side elevation of the same machine with portions thereof removed. Fig. 3 shows a detail of construction, a portion of the shower pipes and the header to which they are connected, in plan view, partly 1n section.
In Figs. 4 and 5 we have shown sectional end elevations of the machine, the sections in these figures being taken on the lines 4-4 and 5 5, respectively, of Fig. 2 but drawn on a somewhat larger scale.
Fig. 6 is a plan view of a' portion of the machine. This section is broken away on the line 6-6 of Fig. 2. The shower pipe headers are shown in sectional side elevation in Fig. 7, the section in thisfigure being taken on the line 7-7 of Fig. 6. A detail of a part of the driving and controlling mechanism. is shown in side elevation in Fig. 8.
vLike characters of references designate corresponding parts in all of the figures.
10 desi 'nates a tank or receptacle which is adapte to contain water. 11 is acover therefor. The tan-k is supported by pedestals 12, 12, each of which is carried up over the sides of the tank and forms bearings for transverse shafts 13 and 14. l,
15 is a bed-plate suspended between the lower ends of these pedestals and rigidly connected therewith for supporting certain parts of the apparatus.
Projecting from what we will call the front end of the machine is a fixed shelf 16, and at the opposite end is pivotally connected a discharge chute 17. At one side of the tank a gage 1S may be connected to show the amount of water therein.
19 is a vent pipe or stack projecting from the upper partA of the cover 11.
20 1s a motor mounted upon the bed-plate l5. This is geared to drive a pump 21 and also a shaft 22. On the other end of this shaft is splined a clutch member 23 which is intermediate the hubs of a pair of bevel gears 24 and 25, each of which is loosely mounted upon the shaft. These gears are' in mesh with other bevel gears 26 and 27, respectively, which are affixed to the transverse' shaft 14. By means of a pivoted forked lever 28 and a rod 29 which runs to the front end of the machine the clutch member may be Amanually moved into engagement with either of the gears 24 or 25 to drive them, or into an intermediate position where it may run freely between them.
Affxed to the shaft 14 inside of the receptacle are two sprocket wheels 30, 3.0, the upper peripheries of which are at about the level of the dividing line between the tank and its cover. 31, 31 designate a similar pair of sprocket wheels on the shaft 13. Between these sprocket-wheels run two endless sprocket-chains 32, 32. Stiff wires 33, the ends of which may form the pivots for the links of these chains. run transversely across from one chain to the other so that the two chains with these transverse wires form an open endless belt, which, as will appear hereinafter, is to be used as a conveyer.
Running longitudinally through the tank are guides 34 over which the lower portion of the chains 32 run so that these guides support this portion of the .conveyer belt. Other longitudinal guides 35 support the upper part 'of the belt and hold it against lateral or vertical movement.
Above the upper surface of the conveyer belt is a frame preferably constructed of wire which, as shown in the drawings, comprises transverse bridge-pieces 36 to which are connected straight wire rods 37. The
bridge-pieces may be so shaped that they conform somewhat to the ordinary shapes of such dishes as are to be cleaned by the apparatus. This may be seen in Figs. 4 and 5 from which it may be understood that the higher central portion is madeto pass over cups, bowls, and the like, while the other lower and wider parts are meant to accommodate shallower and wider dishes such as saucers, plates, and platters. The rods 37 are parallel and serve to prevent such dishes as are passed through .the machine from slipping out of position upon the conveyer belt.
A pipe 40 leads from the lower portion of the tank to the suction inlet of the pump 21. The outlet of the pump is connected by a pipe 41 to a cross pipe in which are valyes 42 and 43, with inlet pipes 44 and 45 which are connected with the shower pipe headers 46 and 47, respectively. Pressure gages may be provided between the valves and the headers if desired to show the pressure in each of the headers. I
A plurality of shower pipes 48 project transversely from the header 46 underneath the Vupper portion of the conveyer belt. These are provided with orifices through which jets of water are thrown upward, but preferably at different angles oblique to both longitudinal and transverse vertical planes. Similar shower pipes 49 project transversely from the headers 47 above the upper portion of the conveyer belt and above the guides 37. These are provided with orifices through which jets of water are thrown downward at different The different directions in which these jets may be thrown is indicated by dotted lines in Figs; 4 and 7, although it is to be understood that the different jets from any one of the shower pipes may be directed at different angles.
50 designates a water pipe from any suitable source of supply. This is connected through a valve 51 to the base of an ordinary gas water-heater 52. 52A is the gas supply pipe for the heater. Another pipe 53 leads from the bottom of the tank 10 through a valve 54 to the base of this water heater. The water outlet 55 from the heater may be connected through the valve 56 directly with the tank 10 which is below the normal water level therein, or through a valve 57 with a pair of rinsing shower pipes 58, 59, above and below the upper surface of the conveyer belt and beyond the shower pipes 48 and 49.
60 is a baffle-plate which is placed across the tank in front of the shower pipes 48, and extends up over the shaft 13. 61 is another baiie-plate back of the rinsing pipes 58, and this extends up over the shaft 14. Another 'baille-plate 62 is placed transversely across the cover 11 in front of the shower pipes 49, and a` similar plate 63 is placed back of the rinsing pipe 59.
For leading off surplus water from the tank, an overflow pipe 64 is provided.
A desired amount of water may be run into the tank from the supply pipe 50 through the heater 52 with the valves 54 and 57 closed. Qr, if enough water is in the tank, this may be heated by opening the valves 54 and 56, and closing valves 5l and 57. lVhen the water has reached the desired temperature, the apparatus is ready for use. The motor is started and the clutch is thrown to cause the couveyer` belt to be driven by the gears 24, 26, or the gears 25, 27, according to whether a lower or higher rate of conveyer speed is desired.
The pump 21 and its connections are such that the water in the tank is drawn from the bottom thereof, and forced into the headers 46 and 47, and into the apparatus through the shower pipes 48, 49 in opposing jets. By manipulation of the valves 42 and 43 the pressures in the headers maybe regulated. It is desirable to have the effective pressure of the 'downwardly directed jets somewhat greater than those which are upwardly directed so that there will be no tendency for the jets to raise the dishes from the conveyer. This may be done by having a greater number of the upper shower pipes 49 than of the lower ones 48, as is shown, or by making the pressure in the header 47 greater than that in they header 46. The valves 54 and 56 are now closed, 4and the valves 51 and 57 opened. Soiled dishes are then slid in an inverted position from the shelf 16 onto the upper surface of the conveyer and under the guiding frames 36, 37. Some of these dishes are shown in dotted lines in Fig. 2 at A, B. and C. They will then be carried through the passing jets from the shower pipes 48 and 49. The impact of these jets ofwater strike the dishes from many directions and thoroughly remove all extraneous matter frorn them.
After passing through the jets from the -oppositely disposed shower pipes, the dishes are carried between the rinsing pipes 58 and 59 where they are subjected to jets of fresh warm water which will rinse off of them the cleaning water from the tank by which they have been treated. The water fromthe shower pipes and the rinsing pipes clean the dishes thoroughly and warm them so that they dry quickly.
The conveyer belt carries the dishes on l through the machine until at" last they are discharged over an apron 65 onto the chute 17 over which they slide onto -a table on which they may be sorted, and'from which they may be collected.
Fresh water is continually introduced intothe machine while it is in operation through the rinsing pipes 58 and 59. lThe surplus v which is removed from the dishes oat on the to of the water and' therefore run off throug the overflow.
What we claim isl. In a dish washing machine, an endless' carrying belt having a substantially flat open carrying surface, means for producing a movement of said belt in one direction, oppositely directed stationary shower pipes on opposite sides of said belt, a tank, an overiow therefor, means for circulating the water in the tank through the shower pipes and causing it to impinge against articles on the belt in different directions; and opposltely directed rinsing pipes on opposite sides of said belt beyond said shower pipes in relation to the movement of the belt for rinsing the articles on the belt, which serve as means for introducing fresh hot water into the tank. i
2. In a dish washing machine an endless belt having a substantially Hat open carrying surface, means for producing a constant movement of said beltin one direction, a pair of stationary supporting guides arranged to engage the edges of said belt and to hold the carrying portion thereof in a horizontal plane, a set of stationary shower pipes above the supported portion of the belt and another set of stationary shower pipes below said portion of the belt, independent valves for controlling the inlet to each set of shower pipes, each of said shower pipes being provided with aI plurality of sets of orifices for discharging water under pressure toward the other set of shower pipes but in diierent directions and arranged to have said water jets impinging upon articles upon the belt, a tank, means for circulating water from said tank through said shower pipes, said shower pi es being so arranged as to cause the effective pressure of the water from the upper shower pipes to be greater than that from the lower shower pipes; a pair of rinsing pipes one above and one below said supported portion of the belt and beyond the shower pipes in relation to the movement of the belt, which serve as means for introducing water into the tank and an overflow pipe from the tank.
3. In a dish washing machine, a conveyer having an open carrying surface arranged to have a constant movement in one direction, a stationary guiding frame over the carrying surface, a stationary shower pipe above said surface, and another stationary shower pipe below said surface, and means for forcing water from each of said shower pipesagainst said surface of the conveyer.
