DISHWASHING MACHINE.
T 0 all whom it may concern: 7
Be it known that I, CHAnnn Orson, a citizen of the United States,- residing at Lafayette, in the county of Nicollet and vinne'sota, have invented certain new and useful Improvements'in Dishwashing Machines, of which the following is a specification, reference being had to the accompanyingdrawings.
This invention relates to an improved dish washing machine, and 'anobject is-to provide an apparatus of this kind, wherein the dishes are received at one end to be washed or thoroughly cleansed and takenfrom the other endof the machine, passed through the machine to be rinsed, in combination with a suitable rack at one end of the frame of the machine to support the dishes and permit them to be drained.-
Another object is to provide an apparatus of this kind wherein means are operatively mounted in the frame of the machine for conveying the dishes under the brushes in order to be washed and rinsed.
-Still another object embodies a machine of this kind including a rotary 'fountain brush for washingcups and the like.
Additionally the invention aims to provide an apparatus of this kind wherein the rotary brushes which are used for washing the dishes, so as to thoroughly cleanse them as they pass under the brushes.
Furthermore it is the aim to provide a sure so that it will pass into the brushes with suflicient force tosprayfrom the. brushes upon the dishes.
Furthermore, the invention also provides a dish draining rack with means for holding the dishes on their edges so that they will properly drain, the top of the base being inclined and perforated so that the water will drain into the chamber in the base. While the design and construction at present illustrated and set forth is deemed preferahle, it isobvious that as a result of a reduction ofthe invention to a more practical form for commercial purposes, the invention may be'susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed. The invention comprises further features Specification of Letters Patent.' Application filed June 5,

eferring to the drawings, ldesignates a housing or superstructure and 2 denotes a base,.which supports the housing or superstructure and is provided with a chamber orfcompartment 3 for the reception of the refuse water. The base 2' is mounted upon suitable supporting legs 4, there being a drainoutlet opening at the center of the bottom of the chamber, and communicatively connected with this opening 5 is a drain pipe 6 provided with a valve 7. The top of the chamberB is inclined and is perforated as at 8 to permit the refuse water to drain into the chamber. One end of the top 9 of the chamber is extended and has transverse ribs 10 to be en aged by the edges of the dishes when they are supported in inclined positions and to prevent them from of the top 9 of the chamber has perforationsflfto permit the water'draining from the dishes to pass into the chamber 3. A suitable rack 12 is secured to the sides of the base as at 13 and arches over' the extension of the top of the and 23 about which chamber. This extension has a marginal flan e to retain the water on the top so that it w1ll. drain into the chamber. The extension isslightly inclined as shown, to facilitate the draining of the water. A clamping rack 14 is pivotally mounted at 15 on the sides of the base of the housing and havin coil springs 16 to hold the clampingrac against the dishes, which are arranged on their edges on the ribbed extension of the top of the chamber to prevent displacement of'the dishes, and to'hold them so that they can readily drain. I
The housing includes the sides. 17, which are supported on the bottom of the base, and support the various washing brush cylinders. Mounted in of the housing are rollers 18, 19, 20, 21, 22
a rubber or other suitable conveying belt 24 travels. The belt 24 passes over the roller 18 under the roller 20, over the roller 22 and then over the roller 19 and the roller 21, and thence over the roller 23 and back to-the roller 1.8. This belt is corrugated as shown at 25, and travels in the direction of the arrow a so that when the dishes are arr'angedone at a time fiatwise on the belt they will be carried in the direction of the arrow a andtthen move in an inclined directionupwardl'y where they can be extracted. As the dishes are traveling with the belt they are thoroughly washed by the brush bristles of the rotary brush cylinders 26, which are mounted in bearings of the sides 17 of the housing.
These rotary brush bristles rotate toward each other and downwardly as indicated by the arrows b. The bristles 27 of the brushes are long enough so as to sweep over the dishes as they pass thereunder.
Mounted in bearings of the sides of frame above the rotary brush cylinders are rollers 28 over which a rubber or other suitable belt 29 travels. This belt 29 is endless and has its outer surface corrugated similar to the belt 24. The dishes as theyare washed by placed on the belt 29 and returned to the end of the machine where they were first inserted. As the dishes are carried by the belt 29 they are further brushed, and are rinsedby the water from. the spray or sprinkler pipe from one side of the housing to the other.
The brushes 31 and 32 for additionally brushing the dishes as they are carried by the belt 29, are mounted in bearings of the sides 17 of the frame of the machine.
1 The brush cylinders are hollow and have perforations 33 so that water can spray therefrom. One end of each of the brush cylinders is provided with a reduced exten- 'sion 34 to which a couplingpipe 35 is connected by means of the nipple 36. This nipple has a swivel opemng bearings on the sides 17 noted that by opening the the rotary brush bristles are' 30 which extends transversely connection with the re-- duced extension, there being a washer 37 to plrevent excessive leakage of the water. I ounted upon the frame 1 is a water receiving tank or reservoir 38, into which water under pressure may enter by means of the supply pipe 39. Connected to an outlet 40 of the tank or reservoir is a valve 41 which connects to an auxiliary casing 42 having a chamber 43. The chamber 43 is provided with outlet openings 44 to which hose 45 and 46 are connected. These hose 7 45 and 46 are in turn connected to the pipe couplings 35 so as to convey water. fromthe 4 reservoir into the hollow rotary brush cylinders. A pipe 47 also extends from the chamber 43 and is connected at 48 to the supply pipe 30 which" is disposed transversely of the upperpart of the frame in a position substantially over the central-portion of the conveyor belt 29. It will be or closing the valve 41 the water into the rotary brush'cylinders 26 and the spray pipe 30 may be controlled. The rotary brush cylinders at certain of their end portions are provided with openings 49 having closures 50 which when 0 en, soap shavings may be inserted so that w iien the water enters the cylinders and then sprayed therefrom, it is fit to remove the grease from the dishes. Mounted upon one of the extensions 34 of one of the brush cylinders is a. bevel gear 51, which meshes with a bevel gear 52 on a tubular shaft 53, which is mounted in bearings 54 of one side of the housing. A tubular coupler 55 is 'mounted in abearing 56 of one side of'the housing and telescopically fits into the shaft 53 so as to carry water thereinto. A short pipe 57 is connected to the tank or'reservoir and has a valve 58. A hose or tube 59 connects the valve 58 and the coupling 55 so that when the valve 58 is open water will pass from the tank or-reservoir under 'ressure through the tubular shaft 53 and t ence to the cup washing brush 60. This cup washing brush comprises" a semi-spherical hollow head 61, which is threaded or otherwise fastened at" .62 to the tubular shaft 53. This brush head is provided with radially projecting brush bristles63 and is also supplied with perforations 64. The brush bristles act to remove the dirt from the interior of the cups or other hollow' dishes, while the water spraying through the perforations act to wash the dirt and the like from the cups and then into the chamber of the base. It will be noted that other forms of dish washing fountain brush may be attached to the tubular shaft 53, inorder to wash vari-'=-l '25 ous shapes of dishes instead of passing them through the machine on the belt.
A gear 76 is mounted upon one end of the roller 18 and is in mesh with the gear65 so that power may be transmitted from the gear 65 to the conveyor 24. In other words, it will be noted that by manipulating the rotary brush cylinder carrying the gear 66, the remaining moving parts of the apparatus are capable of movement so as to perform the function of washing and rinsing the. dishes and carrying the dishes through the machine. One end of the base of the frame of the machine has an extension board 77 on which the dishes to be washed may be placed. The dishes are passed one at a time 1nto the opening 78 of one end of the machme upon the conveyor or belt 24 and then they are removed from the other end of the machine and placed upon the conveyor 29 so that th y can be rinsed and further washed by passing under the brushes 31 and 32- and the sprinkling pipe 30. The dishes are removedfrom the upper part of the housing of the machine through the opening 7 9 andare placed on the drain rack as shown in the sectlonal view of Figure 3. The upwardly and inwardly'extending part of the conveyor belt is adj acent the extension flange 80. .One side of the casing 1 at a point immediately above the extension flange 80, an opening 81 1s formed, so as to permit the removal-of the dishes, and the insertion of the dishes between the conveyor 29 and the brushes 31 and 32.
