5 sed ior'other gun-poses. Mien is characterized the fact that a single pair or set of bolts-r enabled v v to clamp the u-ts ofthc lieu-x." container or 15 vessel, to 1; ion' the biting element and to secure it in. opera 've position, no a(llitlonal fastening means heating element a unitary strueture and .-is eharaeterized by'tlie feet that theqo'arallel portio is of theresistance or heating coil-s areseparated. by an insulating medium to. prevent electrolyticaetion between the parts of the separate portions and by the fact that the upper part of each. coii portion is straightened out that it outas readily, if the Water supply is turned off- While the electric current is still flown Furthermore the intake and outlet are '35!- l'anged symmetrically with" respect to the heating. coils and this in conjunction with the separating Wall between the coils, car the heat to be abstracted from the coils uni formly. $5 In the accompanying drawings which illustrate an embodiment of my invention Figure .l is a side elevation of one form thereof and showing also the manner in which it ma be attached to a spigot and connected to an electrie circuit; Fig. 2 is vertical section oi the heater; Fig. 3 i cross section on 1e line 33 of l 4 is a side slot on of one form of'heatli i unit; and 5 is :1 fr: nentary view 0'" 4i soils shown in g the support for the 'Fig.

I have v of the fluid, one i i, i u it easy to .mzzuui and iuoilitatuig the assembling of parts. It comprises an outer metal oyliiulor or tube 1., and on inner poo celain or et insulating cylincle clamped v by means of bolts between heats or e'lul disks 5, 6, preferably of metal, with interposed gaskets 7', 8, to form'tight joints. The

The ead lmakes ano exoeedingly simple" ma efieiont llhof said stem, and terminal posts carried by said cap and having connecting members passing through channels in said cap and secured to the free ends of said resistance sections, said ends having a straight portion to decrease the'amount' of heat generated in a given length of'the-heating unit.

6. An electric fluid heater, comprising a heating resistance element provided With parallel co1led;par.ts separated by an insulating partition Within the fluid heater,'an inlet and an outlet at opposite ends of said parallel 7 parts respectively and symmetrically arranged with respect to the combined resistance parts, so thatthe fluid is caused to flow-through the coils in equal streams and thereby subject thecoils to like conditions.

7. An electric fluid heater, comprising a coiled resistance, the upper end, of saidcoiled resistance being straightened out to provide .a 'certai n length of reslst-ance in I which a' decreased amount of heat is generated in a given space, so that the coils will not be burned out if the fluid supply is cut off only fora short time in which the surface of the fluid is within the spaceof said certain length.

In testimony whereof I aiiix my signature in presence oftwo Witnesses.
