HEATING APPARATUS.
o (ZZZ whom may concern:
' lie it known that I, liLeNUEL Booze, a
citizen of the Re ublic of Guba residin at,
OReilly St, Number 6?, Haba-na, Cuba,
- have invented new and useful Improvements in Electric Lea-ting Apparatus, of which the following is a specification.
This invention rel tee to electric heating apparatus, anc. its object is to provide an apparatus which is highly etlicient for the rapid heating of the water, and Suppl ing the hot water in continuous and uninterrupted stream, Another object is to provide awater hea er-which is adapted to an electric circuit of 11G volts just as much as to one of volts.
The invention is described with reference to the figures of the annexed drawing, in which:
. Figure l is side elevation, partially broken away of an electric heating apparatus constructed according to this invention.
2 is a rertioal central sectional View thereof,
And Fig. 3 is e trensverse sectional View taizen on line of f This h after consists of a casing or double jacket formed oi two iron tubes 1, 1, although it can be of any electrical conducting or non-conducting material whatsoever. These tubes are closed at their opposite ends y two 2 3 iiiade of an insulating aste and in these two plugs there are in-. rted, one within the other, two concentric ubes l and 5 made of an electrical conduc ng r terial, such as iron. As clearly shown in ig. :2, the wells of tubes i and 5 are in par-.llelisin. central 5 has one end =01 inserted in an Qerti e ll formed within the lower The central 5 has near apper end a lateral h is which establishes coumaunication between the interior of said 5 space 8 intermediate between thetwo tubes iililiil 5. The tube e is formed lower end with two lateral holes 9 which esteblish communication between the space 8 the space 10 intermediate between the'tube l and the inner tube 1 of the outer The holes 9' are of: greater hen the low threaded end tube 1 is screwed was 11 nade oi'inetal or of any suitable material, such cap being formed win e central bushing 12 in which istmeaded a pipe which serves to estab the hole I or" central tube 5.

lish communication with the interior of the central tube 5 with water supply pipes, not shown. 0n the upper threaded end of tube 1 is screwed a metallic cap 1%, formed with a central bushing 15 and into which is inserted an insulator ring 16 through which pass two conducting cables or wires 17 and 18 which carry the electric current from any approp 'iate supply. These cables are" connected to terminals 19 and 20 on the conducting tubes 5 and respectively, whereby the electric current is transmitted to the two tubes -l and 5. In the inner tube 1 of the double jacket there is threaded in a latei'el aperture 21 arranged in radial alinement with the conin'nuii'cating hole 7, an overflow pipe 22 which passes through a corresponding aperture in the outer tube 1. At a point diametrically opposite to aperture 21 there is connected with tube 1 a pressure counterbalancing pipe 22 which passes through a respective aperture in the outer tube 1. of the double jacket and is opened to the atmosphere at its upper end.
The operation of the apparatus is as follows: The water that enters through the lower pipe 13 will penetrate into the central tube 5 and pass through the upper hole '6" to thespace 8 intermediate between the two tubes 4 and 5, descending through said intermediate space down to the lower part thereof, wherefrorn it goes out through the holes ductin tubes or electrodes the electric curv a; s
rent will pass between the inner surface of outer tube i and the outer surface of inner tube 5, through the particles of mineral salts in the water interposed between the walls of both tubes. These particles of salts act as metallic resistances hat become heated and transmit their heat to the surrounding water andthe walls of inner tube5 and outer tube 4:. Thus the water that arrives from the central tubeb will be heated when passtherethrough by virtue of the contact with its wall. Clhe water that comes out through holes 9 to the space 10, and rises up through this space to be discharged through the overflow pipe22 is heatedby contact tor Goinmunication with the atmosphere is established by tubez permitting the hot water to lischarge through the overflow pipe 22 infa continuous stream. The temperature of the discharged water is vnearly that of boiling water which is due to the vfact that the apparatus is constructed so that the water receives the maximum- -amount of the heat produced by the electric current and to the gradual heating of the Water, since same, is slightly heated before same is subjected to the action of the elecone hole; 7 and two diametrically opposed holes.9,asindicated in Fig 3 of the drawings, but for a circuit of 110 volts two holes 7 are used which-establish communication between the 'central tube 5 and tube t, and three holes 9 spaced equidistant apart and establishing communication between the her tube 1.
Itis obvious, therefore, that the number of communicating holes between the two conducting tubes and between these and-the" conducting tube 9 and the'double jacket in-- casing at a point adjacent to the upper end double jacket casing can widely vary, as well 7 as the form of this casing, wlthout materially altering the spirit of the invention, which is .as pointed out. in the appended claims. r
What I claim is;
1. An electric liquid heater comprisin an outer-casing, an inner casing insulated rom the outer casing, a cylindrical electrode within said inner casing and spaced andinsulated there from,a sec'ond cylindrical electrode within the first electrode and spaced and insulated therefrom, an inlet 7 pipe communicating directly with the inner electrode, an outlet pipe extending through the outer casing, a cylindrical electrode within said inner casingand spaced and insulated therefrom, a second cylindrical electrode within the first electrode and spaced and insulated therefrom, an inlet pipe coln municating 7 directly with the inner electrode, an outlet pipe extending through said outer casing and communicating with the inner casing, said electrode being perforated to permit circulation of a liquid from said inlet pipe to and through said electrodes and into said outlet pipe, and a steam outlet pipe communicating. with said inner thereof.
3.- An electric liquid heater comprising a liquid tight casing, a pair of electrodes mounted in said casing and insulated from each other and from said casing, means for circulating a liquid between and extef-iorly of said electrodes, and means for preventing back pressure in said casing whereby the circulation ,of the liquid will be rendered continuous and uninterrupted. i In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
