To all whom t may concern:
Be it known that I, JAMES R. LAwsoN, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Improvements in Electric Heaters Liquids, of which the following is a speciication. l
My invention relates to new and useful improvements in electric heaters for liquids. Its object is to provide a portable electric heater of such a size as to be easily immersed in any ordinary water vessel, and adapted to be connected with any common lighting circuit by means of a plug and socket.
The object is more specifically to provide an electric heater for liquids which shall consist of two electrodes mounted within a suitable casing and spaced from each other, it being possible for the liquid in which the heater is immersed to circulate between the twoelectrodes, forming a closed circuit between the same and o'ering a suiiiciently high resistance to produce the necessary heat.
Finally the object of the invention is to provide a device of the character described that will be strong, durable, simple and eiiicient, automaticA in operation when inserted in the fluid to be heated, and also one which will be comparatively easy to construct, and which will not be likely to get out of working order.
With these and various other objects in view,vmy yinvention has relation tol certain novel features of construction and operation,
an example of which is described in the following speeiication, and illustrated 'in the accompanying drawing, wherein:
Figure l is a side elevation. of the heater in artial section, the upper portion of the,
casmg being broken away. Fig. 2 is a vertical sectional view taken on theline m-w of Fig. 1. Fig. 3 is a sectional view taken on the line 3/--3/I of Fig. 2'. Fig. l is a bot- 1 designate similar parts in all the gures,
the lett/er A denotes the tubular casing of the heater, which is provided in its lower portion with a number of' perforations B, the Vpurpose of which .will be explained hereinaftenj Within this casingare mountedV two electrodes C and D, the former being a hollow cylinder spaced from the casing A, and the latter being a cylindrical rod centrally mounted within the casing and spaced from and within the cylinder C. The electrodes C and D are of even length and are held rmly 1n their proper relative positions by a plug E at their lower extremities and a plug F at their upper extremities. The plug E has a flange G upon its top surface, and the plug F has a similar flange H upon its under surface. The Velectrode D has its extremities seated within the flanges G and H, and the electrode 'C has its extremities seated over said flanges. I
The electrical connections to the electrodesl C and D are denoted by the letters J and K respectively. An air tight and water tight casing 1s provided between the plugs L and F for these electrical connections J and K, the space about the connections will thus be kept dry and electrolysis of the connections thereby prevented. l Y
Wires extending from these connections through a plugL xed in the upper extremity of the casing may be extended to any suitable source of current, eitherdirect or alternating. The upper extremities of the casing are turned over to prevent upward displacementof the plug L, and an annular groove M is formed in the casing below the plug to prevent downward displacement thereof. A water tight connection is thus formed. ln annular groove N is also provided in t-he casing directly above the plug F preventing upward displacement of the same, and forming a. water tight connection between the plug and. the casing. The lower extremity of the casing is turned inward to prevent downward displacement of the plug E. This plug is provided with.
water has become highly heated, itmay es- 110 liquid to traiferse an extended path through t `the heater, the
uid is brought into contact with a large heating;` surface so that its teinperature may be quickly raised.
The electrodes C and D will be preferably con'iposed ot carbon since this clement is not subject to the destructive action of electrolysis such as would occur it metals were used. The plugs lt., G and L will be prei'- erably made of porcelain although other forms of insulating` material might be made to serve the purpose.
What l claim is:
l; In an electric heater., the combination with an elongated casing having a plurality ot apertures in its lower portion., ot an insulating plug mounted in the lower portion ot said casing and provided with a plurality of apertures, an insulating plug mounted in the upperportionot the casing and tormiingr anwater tight connection therewith, a pair of electrodes mounted between said plugs and separated by a space, with which'space the apertures in` the lower plug communicate, and a plurality ot apertures provided in the upper portion of one ofsaid electrodes.
2. ln an electric heater., the combination oi an elongated casing, a plug' ot' insulation material forming an air tight and .water tight partition in said casing, a plug` of insulation material closing one end of said casing, concentric electrodes carried by said plug' and said partition, the outer electrode fd 3 l.
and said casing having provision tor the circulation oli water between said electrodes and between the outer electrode and said casing, electrical connections for said electrodes projecting through said partition and a plug` of insulation material closing the other end of said casing and forming an air and water tight inclosure for said electrical connections.
3. ln an electrical heater, the combination with a casing; of an insulating plug closing one end of said casing, an insulating plug` forming' an air tight and water tight partition in said casing, a solid inner electrode and an outer electrode carried by aid plugs, said outer electrode being spaced from the inner electrode and from said casing and said outer electrode and said casing having,` provision for the circulation for duid therebetween and between the inner electrode and outer electrode, electric-al connections for said electrodes projecting through said partition, andan insulating plug closing the other end of said casing" and forming an. air and water tight inclosure for said electrical connections, said electrical connections having` provisions for the connection with a supply source of electricity.
d. lin an electrical heat-er, the combination with an elongated casinghavingapertures for circulation ot water therein at the lower portion; ot a pair of electrodes mounted in said casing land spaced from each other and from said casing, an air and water .tightinclosure beingformed in the upper portion of said casing` and electrical connections tor said electrodes extending therefrom into said air and water tight casing, said electrical connections having` provision for connection with a supply source of electricity.
ln testimony whereof l have signedmy name to this specification in the presence of two subscribing witnesses.
