My invention relates to electrical'heating apparatus for liquids. 7
It isthe object of my invention to provide means of very rapidly heating liquids, particularly volatile liquids, such as oils, by inserting in the liquid in direct contact therewith the heating element through which the current is flowing.
It'is a further object to provide such a heat ing element that may be used with any type of current.
Referring to the drawings:
Figure 1 is an elevation of one side of the heating element of my invention;
Figure 2 is an elevation of the other side;
Figure 3 is a diagrammatic View of the arrangement of the electrical feed wiresof the heating ribbons used as resistances;
Figure 4 is a section on the line 4+4 of Figure 1;
Figure 5 is a section on the line 55 of Figure 1; 1
Figure 6 is a'section on the line 6 6 of Figure 1; 1 I
Figure 7 is a section through a portion of Figure 1 showing the installation of a supv plementary telescoped concentricinsulation support in order to give greater resistance in the ribbon area in the liquid.
Referring to the drawings in detail, 1 is a tubular member of porcelain, or other insulation material, which isprovided with a pair of spiral grooves 2 in which are located a plurality of copper, wires 3 which form, respectively, the positive andinegative sides of a circuit. Such wires are encased in an'insulation of varnished fabric 4. The two cables thus formed are encased in a rubber housing 5. The free ends of these cables enter the bottom of the insulator 1 and thence make their exit in separated condition into the spiral grooves 2 on the outside of the container and then re-enter the hollow interior of the insulator as at 6 where they cross over being held in position by the set screws or screw bolts 7. The free ends are then connected to the resistance ribbons'8 that are wound around portions of the insulator in the grooves 9 through the apertures 10, the

insulator being hollow at 11. The hollow end is closed by the plug 12.
Referring to the wiring diagram in F igure 3, the ribbons 8 are connected at their free ends to the split cable 3 which is divided into two parts 3a and 3b. 3a and 36 are connected to the respective ends of the ribbons 8, which ribbons are connected together as at 13 bons constituting the resistance are wound continuously.
These ribbons may be held in position by horizontally disposed retaining bands 15. The inner insulator 14 is spaced from the outer insulator 1 by the spacing studs 15a.
