ELECTRIC WASHING-MACHINE.

Specification of Letters Patent. Patented lllar. 19, 1912.

Application filed December 11, 1911. Serial No. 665,029.

T 0 all whom it may concern Be it known that I, lVnmL-mt D. J ones, a citizen of the United States. and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Electric \Vashing-hlachine, of which tion.

The invention relates to washing machines in which an electric current is passed through the washing liquid from one electrode to another.

a new and improved electric washing .machine having electrodes arranged in the tank or vat, in such a manneras to insure the passage 'of the electric current through the washing liquid without danger of it passing from one electrode to the other by way of the walls of the tank or vat, to prevent stray or extraneous matter of the articles to be washed 'from c'omingin contact with the electrodes, and to reduce the danger of an operator coming in contact with:

ings forming a part of this specification, in

' which similar characters of reference indicafe corresponding parts in all the views.

Figure 1 is a longitudinal central section of the electric washing machine; Fig. 2 is an enlarged face view of one of the electrodes and its supporting or carrying plate of insulating material; Fig. 3 is a sectional plan view ofthe'same on the line 3-3 of Fig. 2-,

and Fig. t is across section of the same on the line-H of Fig. 2.

The tank or vat A is adapted to contain water or other washing liquid and is provided on the top with a cover B and within the tank or vat A is arranged a receptacle for containing the clothes to lie washed and preferably made in the form of a cylinder having a perforated rim. lhe shaft D of the receptacle C is journaled in suitable bearings arrai ged on the ends of the tank or vat A, am one outer end of the shaftD is-provided wi .21 means connected with other machinery for iinparting a reversing rotary the following is a full, clear, and exact descripmotion to the receptacle C, the said means being preferably in the form of a gearing E connected with a motor of any approved construction. Electrodes F are arranged within the tank A, preferably at the ends thereof, and the saidelcctrodes F are in the form of plates attached to the faces of attaching plates G, of rubber or other insulating material, and secured to the innerfaces, of the ends of the tank or vat A. Each of the insulating plates G is provided with marginal overhanging flanges G for receiving the edges of the electrode F, so as to hold The object of the invention is to provide;

the same in place on the carrying plate G, at the sametime protecting the edges of the electrodes against contact by the operator. Each of the electrodes F is provided with apertures F through which pass lugs G formed integrally on the carrying plate G and projecting beyond the face of the corresponding electrode F so as to prevent an operator reaching into the tank A from coming in contact with the electrode F. The apertures F and the protecting lugs G are preferably arranged in vertical rows located trodes F so as to increase the surface thereof. By reference to Figs. 3 and l it will be noticed that the protecting lugs Gr project beyond the ribs F and hence the operators hand on reaching into the tank A is not liable to come in contact with the electrode F.

In electric washing machines of the type mentioned use is made of an electric current which may run from 110 to 500 volts, and hence the operator is protected against shock iii'om-the electric current. It will also be noticed that by having the insulating carrier plates G the electric current isnot liable to pass from one electrode to another by way of the metallic casing A, butthe current passes through the washing liquid contained in the tank or vat A, It will further be noticed that by having the protecting lugs G stray matter, such as buttons, pins. hooks and other stray matter, is prevented from coming in contact with the electrodes.

Contact points H are arranged in bushings I-of an insulating material and held in the ends of the tank or vat A, the inner ends of the contact points H being soldered or otherwise'connected with the corrdsponding electrodes F. The outer ends of the points H are connected by the usual circuit wires N. Y.. ASSIGNOR or ON'EJTIIRD TowIL Ism A.

- with margina or conductors with a source of electric sup.- ply J, a switch K is arranged in the circuit for turning on or shutting ofi the electricity.

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

1. A Washing machine, comprising a tank adapted to contain a liquid, a perforated revoluble, receptacle in the said tank, electrodes, and plates of insulating material carrying the said electrodes and attached to the said tank at the inside thereof, the said insulating plates being provided with members projecting beyond the faces of the said electrodes.

2. A Washing machine, comprising a tank adapted to contain a fluid, a perforated revoluble receptaclein the said tank, insulating plates-attached to the inner faces of the ends ot'the tanks and provided With lugs projecting from the faces'of the plates, and electrodes in the form of plates overlying the said insulating plates, the said electrodes being provided with apertures through iwhich extend the said. lugs beyond the faces of the electrodes.

3. A Washing machine, comprising a tank adapted to contain a. fluid, a perforated revoluble receptacle in the said tank, insulating plates attached. to the inner faces of the ends of the'said tanks and provided overhanging flanges, and electrodes in the form of plates overlying the said insulating plates and fitting at their edges under the said overhanging flanges.

42. A Washing machine, comprising a tank adapted to contain a fluid, a perforated revoluble receptacle in the said tank, insulating platesattached to the inner faces of the ends of the said tanks and provided with marginal dverhanging flanges and With integral lugs projecting from the faces of the said plates, and electrodes in the form of plates overlying the said insulating plates and fitting at their edges under the said overhanging flanges, the said electrodes hav-' ing spaced ribs and apertures between adj acent ribs and said lugs projecting through i 6. An electric Washing machine provided with electrodes in the form of plates having integral struck up ribs, and apertures betiveen adjacent ribs, and supporting plates for the said electrodes made of insulating material, the supporting plates being provided With marginal overhanging flanges for receiving the edges of thesaid elec-' trodes, and the said supporting plates being provided with lugs passing through the" said apertures and projecting beyond 'the faces of the electrodes. e In testimony whereof I have signed my name to this specification in the presenceof two subscribing Witnesses.
