HEATER on FUMER. l

Application filed February My invention relatesto heaters and fumers and has for its object the provision of an electric fumer of improved structure for heating, vaporizing, or fuming fuel oils, or other liquids, or fluids. Another object is to provide an improved fumer for fuming comparatively heavy fuel oils of low volatility, and to provide an efficient fumer in which the electric heating element is substantially protected from oxidizing fluids, and its endurance thereby greatly prolonged.

In the drawings, Fig. 1 is a central vertical longitudinal section of a fragment of a fuel manifold for an internal explosion engine, showing in central vertical section my improved fumer positioned therein. Fig. 2, is a central horizontal section through said fumer. Fig.3, is a top plan view of an absorbent element, or refractory sponge, forming part of said fumer. Fig. 4 is a central vertical section of said sponge. Fig. 5, is a side elevation of a dry chamber jacket.

In the drawing, 1 is a fuel manifold having an enlarged chamber or catch basin 1 formed thereon or secured thereto, preferably adapted to be closed at its outer end by a cover or plug 2 and gasket 2. Ex-

tending through said plug into the reduced I of a recess 2* formed in its inward portion 2 end, is an electric binding post 3, insulated from said plug in any suit-able manner or by any suitable means, as by mica, gasketsi.

Upon the inward end of said post and in electric communication therewith is an elec tric high resistanceelement of any suitable.

structure or material, as a carbon pencil or rod 5, preferably provided at its opposite end with a metallic conducting cap 5*. Closely surrounded said element 5 is a sleeve (3 of suitable refractory material, preferably of non-porous insulating character, as ce ment. p

Extending over sailcap and sleeve is a close fitting vertically ribbed metallic jacket 7, preferably of copper, in electric communication with said cap or the upper end of said rod and extending downward into the enlarged portion of said recess 2 Said jacket is preferably provided at its lower end with an outwardly directed annular flange 7 extending to the side walls of the enlarged portion of said recess. A sealing ring 8 of any suitable material is preferably pressed down upon said flange in the space be- 13, 1926. Serial No. 88,155.

tween said jacket and the side walls of the enlarged portion of said recess, to prevent leakage of moisture from said recess t0 the interior of said jacket, or below said flange. Said ring is preferably of electricity conducting material, as copper, and adapted to improve the electric communication between said jacket and said plug, constituting an electric ground for an electric circuit in which said rod is included.

Surrounding said jacket and spaced therefrom and extending from said ring' t0v a plane a short distance above said jacket is an exterior sleeve 9 of any suitable material, preferably of brass or copper.

A moisture absorbing element 10 of any suit-able refractory material, preferably asbestos fibre, is positioned'in the space be tween said jacket and said exterior sleeve, and is adapted to contact with the outwardly directed ribs on said jacket and with the wall. of said exterior sleeve and to extend from said ring to a plane a short distance below the upper end of said jacket. Said absorbing element is preferably pressed into cyl indrical form before being assembled in. the. fumerv Said exterior sleeve is provided with an intake port 9 intermediate of its ends, and-said absorbing body or cylinder also preferably has an intake port 1O formed therein adapted to register with the intake port in said exterior sleeve. 3

A screen 11 of any suitable material or struct-ure, preferably of cement, is preferably extended across the open upper end of said exterior sleeve.

An exhaust port or ports 7* are preferably formed in said jacket adjacent to the upper end of said sleeve 6, to prevent the accumulation of any gas pressure which might form in the chamber or contents within said jacket.

Said rod and binding post and jacket and plug are embodied in any suitable electric circuit with any suitable source of electricity, as a battery 12.

In operation, the heavy liquid particles or globules of fuel drawn from acarburetor, not shown, into said manifold by the suction of engine pistons, not shown, allwell known to the art, or condensed from moisture in' the manifold when the engine is cooling, will drop into said catch basin and flow through the intake portin said exterior sleeve into said absorbing element and thereby into contact With the highly heated Walls of said jacket by Which said liquid particles Will; be

fumed, the fumes will be conducted upward by the grooves between said ribs andv will flow out of said fumer through said screen and into said manifold, whence they will be drawn into the cylinders of the eng ne m proper condition for use. The upper end of said fumer preferablyextends slightly above the floor of the body portion of said manifold soas toprevent flooding theupper or exhaust end: of'said absorbent body and avoid-any danger of the fumes being re-condensed' by an overhead flood of liquid.

Said invention is especially effective, use

ful and economical. in: starting a cold engine and in conserving fuel at idling speeds and for preventing damaging quantities of liquid fuel from-reaching" theengine cylinders and lubricating oil.
