ELECTRIC WATER-HEATER.

Specification of Letters Patent.

Patented May 14, 1918.

Application filed May 19, 1914. Serial No. 839,580.

To all whom it may concern:

Be it known that I, Jnssn F. WHnELooK, a citizen of the United States, residing at Dobbins, in the county of Yuba, State of California, have invented certain new and useful Improvements in Electric Water-Heaters; and I do hereby 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.

This invention relates to improvements in water heaters, and particularly to electric devices for heating water.

The principal object of'the invention is to provide a simple electric heater in which the use of wires as resistance elements is obviated.

Another object is to provide a device of this character which is simple in construction, efl'ective in operation and which can be manufactured and installed at a comparatively low figure.

Other objects and advantages will be apparent from the following description, when taken in connection with the accompanying drawings.

In the drawings:

Figure 1 is an elevation of the device.

Fig. 2 is a vertical section on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 1.

Referring particularly to the accompanying drawing, 10 represents a tank which is adapted to receive the water as it is heated. Connected to the upper and lower portions of the tank at one side are the pipes 11 and 12, the pipe 11 being connected with a check valve 13 while the pipe 12 is connected with a faucet or drawing ofi valve 14. Connected to the other end of the check valve 13 by means of a short length of pipe 15 is a T connection 16, this T being connected with a similar T 17 by means of a pipe 18 which is a good conductor of electricity, said T 17 being in turn connected, with the valve 14 by means of a short length ofpi e 19. In-

serted in the lower side of the T 1 and closing this side of the T is an insulated plug 20 through which extends a suitable conductor element 21 formed of any suitable material which is a good conductor of electricity,

Suitably clamped around the pipe 19 is a metal plate 25 having a binding terminal 26 to which is connected another current conductor 27.

In the operation of the device, the tank 10 being filled with water, the current is turned on, and as the water flows through the valve 14 and into the pipe 18 thewater will complete the circuit between the pipe 18 and the carbon element 21 so that the temperature of the water will be quickly raised. As the water temperature rises it will flow upwardly through the check valve 13 into the upper portion of the tank, thus producingv a complete circulation from the tank through the valve 14, the pipe 18, valve 13 and back to the tank.

What is claimed is:

A water heating apparatus, comprising in combination, a water tank, a hollow column of conductive material rising parallel to the tank and having its upper and lower ends connected to communicate with the interior of the tank, said column being formed of electro-conductive material, an electric heating element rising within the column in insulated relation thereto, a check valve between the upper end of the column and the tank and a regulating valve between the lower end of the column and the tank, the water in the column acting as a conductor between the heating element and the walls of the column and the quantity thereof determining the intensity of the heat, and the regulating valve determining the height of the water in the column, whereby to regulate said heat intensity.

In testimony whereof I aflix my signature in the presence of two witnesses.
