to be heated, the same will circulate freely through the wall of the electrodes 1 and 2, and by so doing come in contact with the exterior and interior wall surfaces thereof.

The supply or current wires 8 and 8 are connected at their outer ends to the contacts ofan ordinary lamp plug 13, which fits Within the socket 13.of the electrical fixture 14, the Wires 8 and 8' being of such length as to permit of a considerable range of moven'ient-torthe electrical heater. I The moment the improved heater is placed in the vessel containing the Water to be heated, the electric current having'been pre-', viously turned on, the water enters the annular space 3 through the Water spaces, openings or perforations 12 in the electrode 1, and into the tubular electrode 2 through the bore .6 of the end cap 4- and passes from the interior of said electrode through the outlet openings or perforations12 into the annular space 3, the water connection between the electrodes completing the electrical circuit, causing the current to fiowthrough the electrodes. The electric circuit being thus closed, the electrodes are quickly heated and the water almost instantaneously raised to boiling point. The moment theheater is removed from withinthe'body of water the electrical circuit is destroyed and the heater maybe freely handled Without shock to theoperator, the electrodes quickly cooling off on the destruction of the circuit. Thus the heater is only in action on being placed in the water to be heated, for at'such other times the circuitis an open-one.

While the communication between the an- .nular spaceB and the 'b odv of water to be heated is established by niea'ns of perforations-through the electrode-1 and from. the interior of the electrode 2 by .the'perforations in the wall"ther'eof,-itis obvious that any form of passage-ways for the circula-' tio'n offthe Watermay 'be employed, and, if

sodesired, the perforationsof the electrode 2 may be dispensed with;v theonly' essential being that an established water connection 1 be made between the electrodes. However, the construction illustrated preferred, inasmuch as the water is exposed to a greater heating, surface and the limiting of the water more quickly accomplished than otherwise would be the case.

\Vhile the electrodes are illustrated as tubular and-of cylindrical form, it is obvious that solid electrodes may be employed, and that the shape thereof may-be varied as desired.

Having thus described the invention Whatis claimed as new and desired to be protected by Letters Patent is 1. An electrical water heater, the same comprising. an insulated handle provided with passi ige-ways for the current wires, an

outer cylindrical perforated electrode se cured thereto, an inner cylindrical perforated eleetrode fitted within the outer electrode and secured to said handle to leave an annular water circulating space between the electrodes, an insulated connection between the lower ends of the said electrodes for holding" the saute spaced at such portion,

currentsupply wires extended through the insulated handle and connectedone to-each electrode, and nieansfor connecting the said Wires to-a source ofelec tri'cal supply.

2. An electrical heater for the described rent supply wires, a perforatedouter electrode secured thereto, an inner electrode fitted to said handle to leave a: Water circIl-- lating passage-way etween the electrodes,

an insulated cap separating the electrodes'at.

the lower ends thereof, nd current Wire extended through the in ula-ted handle and connected to the respec ive electrodes.

In testimony-Whereo Ihave signed-my purpose, the same comprising an insulated handle provided with passage-ways-for curname to thi-s specification in the presence of.

two subscribing witnesses.
