DISHI-CLEANER.

SPECIFICATION forming part of Letters Patent No. 544,211, dated August 6, 1895.

I Applieationfiled January 18, 1895- Serial No. 535,391. (N del.)

'appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of refererence marked thereon, which form a part of this specification.

It is the object of my invention to provide a dish-washer wherein all splashing is obviated, which will thoroughly and quickly cleanse of all foreign material dishes placed therein, and which, owing to the peculiarly-' constructed operating mechanism, will require but little power to operate.

A further object is to provide a dish-rack of improved construction and a dasher or agitator of such form that while but little water need be used in the washing process, yet a full and evenly-distributed supply will at all times impinge on the dishes to be cleansed at ani angle substantially perpendicular to their s1 es.

To accomplish these objects my invention consists in the employment of a rotary dasher provided with a water-passage leading from its lower portion to a higher point, whereby the centrifugal force of the dasher will draw the water upward and project it laterally against the sides of the dishes.

My invention further consists in the peculiarly-shaped dish-rack in which the dishes are placed to more effectnallyreceive the force of the water issuing from the dasher; and my invention still further consists in the peculiar driving mechanism and other structural features and combinations, more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a top view of my improved dishwasher with the cover broken away, showing the interior of the machine; Fig. 2, a transverse sectional view taken through the center of the machine and with the cover on; Fig. 3, a detail view of the dasher, and Fig. 4 a

which is supported on removable legs 1, 2, in-

serted in inverted pockets 2, attached to the said receptacle. The bottom 3 of the receptacle A is formed with an inverted depending conical portion 4, through whose apex is an opening, and a drainage-pipe 5 extending therethrough opens into the interior of the said receptacle to provide means for draining the water therefrom. An ordinary hingevalve 6 affords means for closing the mouth of the pipe 5 when the machine is in use. The means for operating this valve consist of a rod 7, pivotally connected to a lever 8, which is fulcrumed at 9 to one of the legs 1, and is vprovided with a curved portion 10, which is adapted to be sprung across the rod 7, to hold the valve against its seat when the machine is in use. This curved portion 10 may be sprung from its seat on the rod7 when it is desired to open the valve '6, as shown in dotted lines.

stance, the upright 13-communicate with the 1 duct 12. The other upright 14 is provided with one large discharge-orifice 17 only, as I find that with this construction the best results are obtained. A web 18 connects the uprights 13 and 14 and is provided with a square aperture 19 for the insertion of the squared end of a driving-spindle, whereby the dasher may be rotated. A dish-like shell 20 is fitted to the base of the dasher 11 to serve a purpose hereinafter described.

The dasher is provided with a thimble-bearing 21, which rests on a pivot 22, extending upward from the bottom 3 of the receptacle A and allows the said dasher to revolve freely thereon. Ribs 23, forming breakwater devices, project upward in the interior of the re- ICO ceptacle A from theinside of the conical bottom thereof.

The dish-rack consists of inner and outer annular rings 24 and 25, respectively. Vires 26, so disposed as to lie tangentially with the inner ring 24, connect it with the outer ring 25, and these wires are placed at suitable distances apart, so as to allow of the insertion of dishes edgewise between them. An upright cage 27 is connected to the inner ring 24 and serves to prevent the dishes from being struck bythe dasher when it revolves. Short legs 28, connected to the outer ring 25, serve to hold the whole dish-rack raised from the bottom of the receptacle A,so that the dishes may the better be held in position and allow the water to drain the more readily therefrom.

B represents the cover of the receptacle A. From the under side of this cover depends a hanger 29, which is drilled to form a bearing 30, adapted to receive a spindle 31, which passes through an aperture 32 in the cover B, and to the upper extremity of which is attached a brush-wheel 33. The lower eX- tremity of the spindle 31 is formed into a square head 34, which is adapted to engage the square aperture 19 in the web 18 of the dasher 11. This spindle is also formed with a shoulder 35 to prevent its dropping through the hanger 29. A large driving-brush wheel 36 is provided witha handle 37 and is adapted to revolve loosely on a pintle 38, projecting from the upper side of the cover B, being held in place by a linchpin 39. The two brushwheels 33 and 36 are thrown in and out of engagement through devices which will now be described.

To the upper side of the cover B is pivoted an arm 40, whose free extremity is grooved or notched transversely to form a recess which is adapted to embrace the spindle 31. To the other extremity of the arm 40 is connected, by ears 41, a spring-rod 42. A catch 43 serves to hold the free extremity of the spring-rod 42, when itis desired to throw the brush- wheels 33 and 36 into engagement. An aperture 44 in the cover B serves as a peep-hole for the operator to observe the condition of the dishes and to fit the spindle 31 into the dasher 11 when the cover is placed in position. Aslide 45 serves to prevent waste of water through the aperture 44 when the machine is in operation, and also affords an opening through which water may be poured.

Having thus fully described my invention, it may be assembled and operated in the following manner: The receptacle A having been mounted on the legs 1 and the valve 6 closed, the dish-rack is placed therein. The dasher 11 is then mounted on the pivot 22. The dishes may now be placed in the rack and the receptacle A suitably filled with water. The cover B is now placed in position, the operator meanwhile looking through the aperture 44 to enable him to guide the head 34 of the spindle 31 into the aperture 19 of the dasher 11. The spring-rod 42 is now sprung against the catch 43; This causes the arm 40 to press the spindle 31 forward and hence to bring the brush-wheel 33 into engagement with the larger wheel 36. By this construction a yielding engagement between the two wheels is brought about and inequalities in speed and the engaging-surfaces compensated for. The water inside the receptacle A will enter the hollow dasher to a, level with that outside, and as the said dasher is rotated the water is thrown in jets by centrifugal foroe through the discharge-orifices in the uprights thereof and impinges on the dishes. Owing to the construction of the shell 20, the dasher is allowed to revolve with little friction with the water and the water allowed to readily enter the said hollow dasher to keep it filled. The ribs 23 serve to prevent whirling or circular currents of water from being generated by the action of the dasher, which would tend to displace and break the dishes in the rack. The dasher may be revolved alternately in opposite directions, if necessary. Owing to the peculiar formation of the dish rack the dishes are held at a proper angle to receive the jets of water which are flirted on them by the dasher.

It is generally found advisable to wash the dishes thoroughly, open the valve 6 and drain off the water, then close it and refill the receptacle A and rewash the dishes with boil- 1 ing water, as they will then dry quickly of themselves. It is generally best to impregnate the water with a little washing soda or like substance during the first washing to the more readily mechanically release the grease from the dishes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a dish washer, the combination with a washing receptacle, of a substantially U- shaped rotary dasher, each arm of which is provided with a discharge orifice, the said dasher being provided with an internal water passage attordi n g communication between the discharge orifices and a receiving orifice formed through the base of the dasher, mechanism for driving the dasher, and a dish rack surrounding the dasher and provided with a series of dish receiving slots tangentially disposed in relation to the path of movement of said dasher, all being so arranged and combined that when the dasher is set in motion by the driving mechanism, water in the receptacle will be drawn up through the base of the dasher and projected laterally and tangentially through the discharge orifices, and impinge upon the faces of the dishes, substantially as described.

2. In a dish washer, the combinationof a washing receptacle having its bottom formed into a depending inverted conical portion, breakwater devices projecting from the said conical portion of the bottom, a substantially U-shaped dasher provided with discharge orifices communicating, by means of an internal water passage, with a receiving orifice in the base of the dasher, said dasher being so disposed that its lower portion projects into the conical bottom of the dasher, driving mechanism for operating the dasher, and a dishrack surrounding the dasher, and having slots adapted for the reception of dishes, and an upright guard portion to protect the dishes from being struck by the dasher, all being so disposed and related that when the dasher is in operation water will be drawn up thereby and projected laterally therefrom against. the dishes, substantially as described.

3. In a dish washer, the combination with a dish washing receptacle, of a centrifugal dasher, a dish-like shell in which the base of the dasher is seated, and mechanism for rotating the dasher, substantially as described.

4. In a dish-washer, a hinge valve, governing a drainage duct from the water receptacle, which is adapted to be actuated by a rod is suitably fulcrumed, and whose free end is provided with an upturned portion adapted to be sprung across the said rod to hold the valve on its seat.

5. In combination with a wheel mounted on the spindle which drives the dasher of a dishwasher, a lever suitably fulcrumed whose free end is adapted'to press the said wheel into engagement with driving mechanism and hold it in yielding contact therewith, through the medium of a spring-rod connected to the said lever and whose free end is adapted to be held by suitable means.

- In witness whereof I affix my signature in presence of two witnesses.
