replacement or repair and whereby the outer surface of the unit is in close heat conducting relation with the container, when the parts are assembled. The container 14 is also water tight, thereby keeping the fluid from the heating unit.

The chamber 5 has its upper end normally closed by a valve 15 which rests upon a seat formed on the support 4. This valve has a circular depending wall 15 which extends down into the chamber 5 to keep the valve from being laterally displaced.

The only normal communication between the reservoir 6 and the heating chamberf is through a tube 16. This tube 16 has its upper end fastened to the valve and provides communication between the reservoir and the bottom of the heating chamber.

When the heating unit 13 is energized the Water in the heating chamber 5 is quickly heated, there being practically no circulation between the Water in the heating chamber and the reservoir while the water initially in the heating chamber is being heated When the water in the heating chamber has been sufficiently heated, iwhich takes only a short time, it may be drawn ofi through the port 12 and faucet 11 it being displaced from the bottom of the heating chamber by cool water which passes from the reservoir down through the tube 16 to the bottom of the heating chamber.

The valve 15 prohibits the cool water in the reservoir from passing into the top of the heating chamber so the only way it can freach .the heating chamber is through the tube 16.

If the water in the heating chamber is not drawn ofi' when it reaches a predetermined temperature then it will raise the vali/'e715 and pass into the reservoir, and cool water will pass from the reservoir through the {Su-be 16 into the bottom of the heating cham- The heating unit, which I employ in the preferred construction, is one made up of a sheet metal channel 17, having its fianges ben-t over to infold a resistor 18,suitably insulated by layers of mica 19. The resistor is preferably of the slotted ribbon type, being doubled over upon itself, whereby its adjacent ends may be conveniently connected to suitable circuit tern'iinals20. With the ri'bbon folded over upon itself, two superim` posed lengths of resistor are pro/vided as shown in Fig. 3, these layers being separated by the mica, which .is also interposed between the layers and the sheet metal walls. In some cases I inclose an additional strip of metal 21 Within the channel, which acts as a cover plate over which the flanges of the channels are bent so that the mica insulation and the slotted ilibbon arepressed between the egverplate and the bottom of the channel. Undeil other conditions7 however, the cover plate may be dispensed with.

In order to control the circuit to the electric heater, I provide a switch 22, which is mounted preferably on the base. The switch may be of any standard construction. I have illustrated a two button snap switch, The switch is inclosed Within an ornamental cover plate 23, which fits over and is suitably held to the base, the cover plate being provided with suitable openings, through which the push buttons of the switch 22 may protrude. The cover plate 23 isalso provided with an insulating bushing 24 through which the circuit conductors enter the inclosure within which the circuit terminals are located. The cover plate is provided with an opening, in which a glass lens 25 of some distinctive color may 'be mounted, a small incandescent lamp 26 being mounted on the base beneath `the leus, said lamp being so connected in circuit that it will remain lighted while the heating current is on, thereby indicating unmistakably to thev operator the fact that the current is flowing. This insures not only against. wast-e of current after the ydesired quantity of water has been heated, but insures also against the attainment of' an excessive temperature, in case all of the liquid should be allowed to boilI away.

The heating chamber may be provided with a short pipe or nipple 27, secured thereto, at the lower end thereofA` whereby a more or less permanent connection may be established with a water pipe, so that the heating chamber and reservoir may be filled simply by turning a valve. In the absence of such a connection the usual procedure is to remove the cover 10, and pour in the water from above.

The above described construction permits the glass globe to be readily removed from the supporting ring 4 Whenever necessary and permits the ready replacement thereof in case ofbreakage. The heating chamber is suspended from the ring 4 and is not used as a support for the ring` the ring being supported independently by the rods or standards 2. Convenient access may be had to the different parts located beneaththe cover plate of the base by simply liftingthe cover plate which slides upwardly along the standards, the latter passing through suitable openings therein. The heating unit may be removed by removing the screws 8 to detach the base from the standards, whereupon the unit may be readily slipped out of its container and as readily replaced therein.

As previously stated the invention is not limited t'o the details of the present construction and accordingly I desire to cover, as falling within the scope of the invention, Whatever equivalent -constructions may be cured to and deperflng below said valve to scribed my name in the presence of two Witconvey liquid from`the resevoir to the bot' messes; tom of the chamber, :1n out et :Lt the top lo said chamber, :ruil u, heating elementproj ect- WILLIAM S' HABA AY JR' ing within said chamber from its closed end Witnesses: and readily removable therefrom.
