CHARLES PALMLEAF, OF SEATTLE, WASHINGTON.

DISH-CLEANER.

SPECIFICATION forming part of Letters Patent No. 499,031, dated June 6, 18931.

Application filed November 3, 1892. Serial No. 450,832. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES PALMLEAE, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Dish-lashing Machines; 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 an improvement in dish washing machines, and my object is to provide an arrangement by whichdishes may be cleaned with facility and thoroughness.

To this end it consists of certain novel features and combinations of parts which will hereinafter appear and be pointed out in the claim.

Referring to the accompanying drawings which represent a machine embodying the essential features of my invention :Figu re 1 represents a side elevation, Fig. 2 a plan view, and Fig. 3 a vertical section, cover removed.

The reference letter a indicates a circular sheet-metal vat or pan provided with the supporting legs I), and tightly-fitting top 0. Formed in the bottom of the vat a at its center is an opening d, which communicates with the water-conducting pipe 6, extending along the bottom of the vat to its sides where it develops into a vertically extending water-tight chamber, fitted with the pump cylinder g, the said cylinder being provided with a series of upwardly-opening flap-valves 72..

Located within the vat a, and adapted to revolve therein, is a wire cage or dish-receptacle t', having a rounded bottom and provided with a supporting-shaft j, the lower end of which is adapted to fit into the socket in secured to the bottom of the water-conductor 6, directly under the opening at of the vat.

Rigidly secured to the shaft j is a miter-gear Z, meshing with a similar gear m, keyed to the end of the horizontal shaft n. This shaft extends the entire length of the pipe e, and is journaled in the bearings 0, secured to its bottom. Keyed to the remaining end of the shaft 01, is a third miter-gear p, meshing with a similar gear on the vertically-extending shaft q, having bearings in the socket r and yoke-bearin g s.

Arising vertically from the sides of the cylinder g, are two standards t, having bearings tt formed in their upper ends. Journaled in these bearings is a shaft r having a doublecrank 2; formed in its middle, between the bearings and directly over the cylinder J. Removably attached to this crank is a pitman w, which is in turn pivotally connected at its lower end to the piston rod w. This rod passes through the cylinder-head at. 10 and is connected to the piston 0:.

Opening into the cylinder 9 at 9 are two pipes or tubes y, y. These tubes extend around to either side of the vat a, and empty therein, one at or near the top and the other at or near the bottom. The use of these tubes will be explained hereinafter.

Keyed to the upper end of the shaft q, is a gear 2" which meshes with a gear ,2, keyed to the end of shaft o. The remaining end of this shaft is provided with a crank a by which the machine is operated. A cook a is located in the pipe E, by which the water contained in the machine may be drawn off.

Formed in the highest portion of the cylinder g, is an opening g, through which any water which may have been drawn into the upper portion of the cylinder, can escape.

To use my machine for washing dishes, the vat is filled with hot water and suds,the dishes placed in the receptacle and the top fitted in place. When this has been accomplished the shaft v,is made to revolve, whereupon, through the medium of the shafts q, n, and j and their gears, the cage t' is revolved among the water and suds in the vat a. Synchronous with this operation the pump 9 is operated by means of the pitman w and w, to throw a stream of water through the tubes y and y into the vat and on the dishes. By this means the water is kept circulating through the machine and sprayed upon the dishes or whatever may be undergoing the cleaning process.

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

In a dish washing machine, the combination of a primary vat or pan, a dish-cage located and revolving therein, a secondary vat formed integral with the primary vat, a water-conveying tube or passage connecting the two and communicating with the primary vat at the center of its under side, a revolving shaft mounted in the water passage and extending vertically into the primary vat Whereat it is connected to and supports the dish-cage, a horizontal shaft located in and extending longitudinally with the water passage and geared to the vertical shaft in the primary vat, a second vertical shaft in the secondary vat and geared to the horizontal shaft, a crank-shaft geared to the second vertical shaft, a forcepump operated by the crank-shaft and communicating with the secondary vat, and tubes connected to the pump and primary vat whereby water is made to flow from the secondary to the primary vat and back by Way of the water-conducting passage, substantially as described.

In testimony whereof I affix my signature in 20 presence of two witnesses.

CHARLES PALMLEAF. Witnesses:

GEO. H. KING, JAMES DIGNAN.
