UNITED STATES PAUL E. ONWILER, Q1 BILLINGS, MONTANA.
ELECTRICAL HEATING DEVICE.
Application filed August 28, 1922. Serial No. 584,851.
To all whom it may concern:
Be it known that I, PAUL E. ONWILER, a citizen of the United States, residing at Billings, in the county of Yellowstone and State of Montana, have invented a new and usefulElectrical Heating Device, of which the following is a specification.
This invention relates to an electrical heating device and has for its object the provision of a heating element that may be easily and cheaply manufactured and that may be connected to a water heater in such .manner that repair or replacement of the heating element may be made without cutting off the supply of water from the heatin system.
Vith these and other objects in view the invention aims to improve generally and to enhance the utility of devices of that class to which the present disclosure belongs,
In the drawing Figure 1 is a view in elevation, there being parts in section, of a device constructed in accordance with the present invention.
Figure 2 is a sectional view of the heating H element or se.
Referring to the drawing the numeral 1 denotes the supply pipe of a water heater and 2 the outlet from a receptacle 3. A pipe connection 4 is threaded to the top of the receptacle and provides for union with the outlets 2. A pipe T 5 has'one branch 6 thereof threaded to the lower end of the receptacle 3, the opposite branch 7 is screw threaded to receive a cap 8 and the other branch 9 has connection with the supply pipe 1.
An electric heating element 10 includes a coil 11 and a head 12 of insulatin material. The coil 11 has a core 13 w ich is reduced at 14 to define a stem 15 and a shoulder 16. A nut 17 is threaded to the stem 15 and the member 12 is located on this stem and clamped between the shoulderand nut. Terminals 18 extend through the head 12 and are connected at their inner ends to the terminals of the resistance ele- The branch l is int riorly threaded at 19 to receive the threaded portion 20 of a coil retainer 21. The retainer 21 comprises a tube 22, having a closed end 23, in which the heating coil is located. The threaded portion 21) is of larger diameter than the tube and is provided with a circumferential flange 24 which abuts the branch 7 to form a water tight joint. The head 12 is provided with a shoulder 25 which rests on the flange 24, the cap 8 housing the head 12 and securing the entire heating element within the receptacle.
In use the device will be connected to the outlet and supply lines of a heating system as shown, water entering the reservoir 3 will be heated on coming into contact with the member 21 and rise through the outlets 2-2.
It will be observed that the construction such that should the heating element need replacement or repair, the cap 8 may be removed and the heating element withdrawn without cutting off the supply of water.
Having thus described the invention what is claimed is 1. A device of the class described comprising a reservoir; an inlet for the reservoir and an outlet therefrom; a heating element including a resistance coil; a stem extended from the coil; an enlarged head surrounding the stem and provided with a circumferential shoulder; means for securing the head to the coil; a housing for the coil said housing having a flange adapted to engage the shoulder .and means for securing the coil within the housing.
2. A device of the class described com,- prising a reservoir; an inlet and an outlet therefor. the inlet having a threaded extension; a heating element; a housing for the heating element and threadedly engaging the extension and a cap coacting with the extension to hold the heating element in the housing.
In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
