SPECIFICATION forming part of Letters Patent No. 392,517, dated November 6, 1888.

Serial No. 261,828. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES Burns KING, a citizen of the United States, residing at Lampasas, in the county of Lampasas and State of Texas, have invented a new and useful Improvement in Machines for Washing Dishes, Fruits, 820., of which the following is a specification.

The invention relates to an improvement in machines for washing such articles as fruit, vegetables, and dishes, the object being to thoroughly wash and drain the same with the saving of much trouble and labor; and it consists in the construction and novel combination of parts hereinafter described, illustrated in the drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 represents a central vertical longitudinal section of the machine. Fig. 2 represents a central vertical transverse section thereof on the line :0 a: of Fig. 1, looking in the direction of the arrow. Fig. 3 represents a plan View of the machine.

Referring to the drawings by letter, A designates the casing of the box, having the floor B and at one end the downward extension C, over which the floor does not extend, and the outer part of which forms the pump-chamber.

c is a transverse inwardly-standing shoulder on the inner side of said extension a short distance above the bottom thereof.

E is a partition rising Vertically above the shoulder a between the sides of the casing A to the upper edge thereof, there being a transverse open space, (2, between the lower edge of said partition and the shoulder.

e e are perforations in the partition, and F is a sieve of wire-gauze or perforated metal extending downward from the partition to the adjacent end of the floor B.

G is a detachable bottom parallel to and covering the floor at a suitable distance thereabove, supported on short legs, as shown, and provided with comparatively large perforations 9. The space between said detachable bottom,the partition E, and the opposite end of the casing forms the washing'ehamber H.

I is a partition parallel and of equal extent to the partition E, and standing between the latter and the adjacent end of the casing, and

i is an air-chamber above said partitions and connecting the same. The space outside the partition I forms the pump-chamber J, and the space between it and the partition E is the water-way K.

L is a horizontal water-way running around the sides and end of the washingchamber and communicating therewith through the perfo rations Zin the side of the latter. The said water-way communicates with the water-way K through the opening Z on one side, as seen in Fig. 1.

M is a flap-valve depending from the lower edge of the partition E and resting against the inner face of the shoulder a, so as to close inwardly, and N is a similar valve standing upward from the lower edge of the partition I, with its upper edge resting against the partition E below the perforations e therein, so that it opens upwardly.

O is the plunger reciprocating in the pumpchamber J and 0 is the rod thereof, actuated by suitable means, such as a lever or crank. (Not shown in the drawings.)

1 is the waterspace between the floor and the perforated bottom G.

The method of operation of the machine is as follows: The machine is supported horizontally over a proper fire-place or stove and sufficient water introduced to fill it to a pointjust below the perforated detachable bottom G, and the pump mechanism then set in motion. \Vhen the plunger aseends,it draws water from the water-space P and extension 0 through the valve M up into the pump-chamber. \Vhen the plunger descends, it forces said water upward past the valve N, into the water-spaces K and L, through the perforations e and Z and into the washing-chamber H, the water entering in jets at right angles to each other and washing quickly and thoroughly the articles placed on the bottom G. The water then descends below said bottom through the perforations therein and returns to the pump, so that the circula tion is continuous. When the articles are perfectly washed,the pump is stopped and all the water descends through the perforated bottom, leaving the articles to drain on the latter. The sieve F prevents any large fragments from escaping into the pump mechanism and interfering therewith, and the air-chamber keeps the jets continuous in the well-known manner.

Having described my invention, I claim- 1. The combination of the washing-chamber, the waterway standing vertically at one end thereof and communicating therewith through perforations, the horizontal water way surrounding the opposite end and sides of the washing-chamber and communicating through perforations with the same, and the pumping mechanism whereby jets of water are thrown into the washingehamber at right angles to each other from the two series of perforations and a continuous current of water is established through the machine, substantially as specified.

2. The combination,with the washing-chanr her having the bottom B, of the vertical waterway at one end of the washingchamber, the horizontal water-way leading from the vertical water-'way, both of said ways communieating with the washing-chamber, and the pumpingchamber at one side of the vertical water-way, substantially as set forth.

3. The combination,with the washingchanr her and the downward extension C of the easing,forming the lower end of the pump-chamher and having the shoulder a, of the partition I and the perforated partition 1* forming between them the water-way K, the water-way L, opening into the water-way K at Z and commun icating with the washing-chamber through the perforations l, the valves M and N,and the plunger reciprocating in the pump-chamber, substantially as specified.

4. The eo1.nbination,with the washing-chamber, the detachable perforated bottom therein, and the extension O, having the shoulder c, of the communicating perforated water-ways K L, the sieve F, extending from the partition E to the floor 13, the valves M N, and the plunger reciprocating in the pump chamber, substantially as specified.

In testimony thatIclaim the foregoingas my own I have hereto allixed mysignature in presence of two witnesses.
