SPECIFICATION formingpart of Letters Patent No. 628,409, dated July 4, 1899.

Application filed January 22,1898. Renewed May 22, 1899. Serial No. 717,801. (No model.)

TottZZ whom it may concern:

Be it known that I, MARTHA J MENDEN- HALL, a citizen of the United States, residing at West Newton, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Dish-Washers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to dish-Washers of that class having a tank anda series of open-wire racks or baskets to receive'the dishes and in which a series of revolving paddles are adapted to throw water over the dishes for the purpose of cleansing them. 7

The objects of my invention are to produce a dish-washer that is easily'operated, simple in construction, strong and durable, and having a simple means of throwing the water forcibly against the dishes when in operation, and, further, that can be operated successfully with a small amount of water.

My invention consists in the construction and combination of parts shown in the accompanying drawings and described in the following specification;

In the drawings, Figure 1 is a front elevation, a part of the large gear-wheel being broken away to show the small wheel. Fig. 2 is a top plan view showing the covers thrown open, revealing the interior. Fig. 3 is a sectional view taken on the line 3 3 of Fig. 2.

A is the tank or box, provided with double covers B, attached to the upperedges of the tank by means of the hinges O. The bottom of the box A is inclined downwardly from each end toward the center, making the center the lowest point, to which the water contained therein will naturally flow. At the rear side is placed the escape-cock E, at the lowest point of the box A, a slight depression sin the lowest point of the box serving to lower the escape-cock E, so that all the Water within the boxA will escape when the escapecock E is open.

To the front of the box A is journaled a gear-wheel D, provided with a crank F. The

cogs on the gear-Wheel D are inside of the rim of the wheel and are adapted to mesh with the cogs of the small cog-wheel G, mounted on the end of the journal 11. The journal I-I extends through the box A, being supported at the rear side by a closed bearing t and in front by a boxing directly back of the cogwheel G. To this journal H are attached a series of paddles I, said paddles being arranged in rows throughout the entire length of the journal H.

The box A is supported by four feet or legs J ,which raise the inclined bottom and support the box A squarely. The covers B are provided with depending flanges K, which fit against the inner walls of the box A when the covers are closed, and thereby prevent the escape of the water when the machine is operated. The covers 13 are also provided at each end with notches 1:, into which the clampbolts to enter, and when the nuts 0: are tightened the covers 13 are tightlyclam ped against the upper edge of the box A.

On the bottom inside of the box A, at either end thereof,are placed semicircular open-wire racks L, which are prevented from coming in contact with the paddles I by means of retaining-pins M, attached to the inner walls of the box A. Immediately above the paddles 1, against either side of the box A, are attached supports 9, upon which rests an open- Wire rack N. Both the racks L and N are provided with spiral wires 0 at their upper edges for the purpose of holding the plates 19 and the saucers 9 separate from one another, so that the water can circulate freely between them.

Across each end of the box A, near the top, are placed open-wire racks O, which are supported by means of the supports 6, attached to either side of the box A; These racks are adapted to receive cups and small dishes f. The box A is also provided with handles 77. at either end. The racks L, N, and O are all removable and may be readily lifted out of the box A.

In operation the dishes to be Washed are placed in the racks L, N, and 0, water is placed in the box A, and the covers B are closed. The crank F on the gear-wheel D is rotated, which causes the cog-wheel G, meshing therewith, to rotate the shaft H, having to the other.

ated as to bring the paddles I to the lowest point of the box, thereby permitting the paddles to throw the water so long as there is any left in'the box and allowing the operator to do the work well with a small amount of water.

The water is Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

In a dish-washer of the class described, the combination of the box A, provided with covers B, having flanges K, and provided on its inner walls with supports 7', and e, and retaining-pins M, with the semicircular open-wire racks L, the center open-wire rack N, the end racks O, and the series of paddles I, mounted on the journal H, substantially as-shown and described.

In testimony whereof Iafifix my signature in presence of two witnesses.

MARTHA J. MENDENHALL.
