Theplates sleeves i8 and [.9 and around the shanks of the plugs 2| and 22, and at the same time tightly clamp the conductor wires 25 between the flanges a and rings 24. In this fashion the plugs and the heating elements are securely fastened in place on the end plates l and 8 and insulated therefrom with leak-proof joints therebetween.

Connecting with the plugs 2i and 22 and leading from any suitable source of electrical current supply are

electrical conductors

28 and 29 having terminals 1 which encircle the outer end portions of the plugs 2i and 22 and seat on the nuts 26, and screwed on the outer end portions of the plugs are nuts 3 which clamp the terminals f tightly against the nuts 26. In this fashion electrical connection from a source of electric current supply is afforded to the electrical heating element interiorly of the cylinder 53 through the electrically conductive plugs 2i and 22 extending through the end plates l and 8.

In carrying out the invention the plug 2i is hollow and is formed at its inner end with a cylindrical opening g leading from the interior of the plug to the chamber A interiorly of the cylinder 5. Projecting in the open out end of the plug 2! is a tube 3! having a reduced outer end portion which extends through the opening 9 and has a tapered extremity h protruding beyond the inner end of the plug 2! constituting a nozzle and which tapered extremity is formed with a needle orifice 2' leading from the tip of the nozzle to a cylindrical bore 7' leading through the cylindrical end portion g and communicating with the interior of the tube 3!. The outer end portion of the tube 3! is formed with an annular flange 32 which seats on the outer end of the plug 2! and is engaged by a gland 33 screwed on the plug 2| and fitted with a packing 36 to seal the joint between the tube 3! and the outer end of the plug 2!.

Extending into the tube 3| is a conduit 35 leading from any suitable source of liquid supply under pressure; the inner end of the conduit 35 being formed with a cylindrical nozzle is extending into the cylindrical bore 7' and terminating contiguous the inner end of the needle orifice i. The conduit 35 is formed with an annular flange 36 which seats on the outer end of the tubeBl and is engaged by a gland 31 screwed on the tube 3! and engaging a packing 38 to seal the joint between the conduit 35 and the outer end of the tube 3!.

In the application of the invention as shown in Fig. 4, the conduit 35 leads from the discharge end of a double acting pump B adapted to deliver a substantially continuous stream of liquid, such as water, to the nozzle h and under such pressure that the needle orifice i will project into the generating chamber A a jet of finely divided or atomized water, or other liquid. The generator is housed in a casing C, as shown in Fig. i, between which and the generator is a heat insulating packing D, and leading from the generating chamber A is a vapor discharge nozzle E connecting with an opening MB in the cylinder 6 intermediate the ends thereof which nozzle is here shown as connected to the intake of a turbine F.

In the operation of the invention electrical current is directed through the heating elements :15 whereby the latter, by reason of their resistance, are heated to an incadescent state, and liquid, such as water, is directed into the chamber A into the space surrounded by the heating elements through the nozzle h in an atomized jet; the water being so finely divided that the heat de veloped in the chamber A will effect substantially instantaneous, or flash, vaporization of the minute It will now be seen that by the use of my invention a very small quantity of water is directly acted upon by a very intense heat within a generating chamber formed to withstand extremely high pressures resulting from the expansion of water to a very large volume of super-heated steam, and that the steam so developed is not retained in the generator but its expansion quality is immediately communicated to a unit as a highly effective motivating medium.

While I have shown and described a specific embodiment of my invention, I do not limit myself to the exact details of construction and arrangement shown but may employ such changes and modifications as occasion may require coming within the meaning and scope of the appended claims.

I claim:

1. In a vapor generator, a cylinder, end walls on said cylinder, electrically conductive plugs extending through said end walls and insulated therefrom, electrically conductive resistant wires leading between said plugs, one of said plugs being hollow, and a nozzle extending through said hollow plug having a needle orifice opening interiorly of said cylinder, means for directing liquid under pressure through said nozzle, and means for delivering generated vapors from said cylinder. 7

2. In a vapor generator, a generating chamber, electrically conductive plugs extending through opposed walls of said chamber and insulated therefrom, electrically conductive and resistant wires connecting said plugs interiorly of said chamber, and a liquid feed, nozzle extending into said chamber through one of said plugs.

4. In a vapor generator, a generating chamber having a wall formed with an opening, a pair of insulating sleeves extending to said opening from opposite sides thereof and insulating packing interposed between adjacent ends of said sleeves and electrically conductive plug extending through said sleeve having end flanges overlying the innermost sleeve, a nut screwed on the outer end of said plug overlying the outermost sleeve, an electric heating element connected to said plug interiorly of said chamber, and an electric conductor connecting with the other end portion of said plug.

5. In a vapor generator, a generating chamber having a Wall formed with an opening, a pair of insulating sleeves extending to said opening from opposite sides thereof and insulating packing interposed between adjacent ends of said sleeves and electrically conductive plug extending through said sleeve having end flanges overlying the innermost sleeve, a nut screwed on the outer end of said plug overlying the outermost sleeve, an electric heating element connected to said plug interiorly of said chamber, and an electric conductor connecting with the other end portion of said plug, said plug being hollow and.

formed with an opening in its inner end, a tube extending into said plug formed with a nozzle having a needle orifice projecting through said opening, and a liquid supply conduit connecting with said tube.
