IMPROVEMENT IN VAPOR-STOVES. y

Specification forming part of Letters Patent No. 185,065, dated December-5, 1876; application tiled October 20, 1876.

subst-ance from which the vapor is formed,

so that it is in no way exposed to its action; second, in the special construction of the burner; third, in the employment of a hood or hollow cone surrounding the burner, for the purpose of. more eectually mixing the air and gas in the burner,and also increasing the draft in the same'.

To enable others skilled in the art t make and use my invention, I will now proceed to describe fully its construction and manner of y operation.

A A represent legs of any proper construction and material, which are secured at their upper ends, in any proper manner, to the ring a, for the purpose of supporting the same, and provided near their lower ends with lugs or l projections al a1, Figure l, adapted to support the platform a2, as shown. This platform a2 is made of wood or other non-conducting material, in order that heat conducted from the burner may not be communicated through it to the tank, which rests upon it. B represents the tank or reservoir, constructed generally of any proper size, shape, and suitable material, which is preferably provided with a central cylindrical wall, b, by means of which a vertical opening, b2, extending through it, is formed. b3 represents a removable cap, closing the filling-opening; and b4 b4, supportingfeet of non-conducting material, by means of which the tank is raised from the non-conducting platform below. b5 represents a venttube, having a very small opening in its top, which is adapted to permit any gas -which may accumulate in the tank t0 escape to the burner, and also to permit the entrance of air when a vacuum is formed in the tank, as will be hereinafter described. C represents a tube,

in the vertical opening of the tank, so that air is permitted to circulate about it on all sides for the purpose of keeping it cool. D represents the wick-tube proper, extending upward a proper distance, and provided at its upper end with a threaded portion adapted to hold the burner, as shown. Its interior is provided y with wick,as indicated inthe drawings. E rep- .resents the burner, consisting of the tube e, having the enlarged portion el, flange e2, and discharge-opening e3 for the gas, as shown. c4 represents a disk or plate projecting from the burner above the gas-discharge openings,

by means of which the gas is thrown out.' equally upon allsides.' e5 represents an inclosing shell or chambenlbrmed of wire-gauze for perforated metal, closedon all sides, by means of which the distribution of the gas is more uniformly and perfectly effected. y

Frepresen ts a plate or cover, secured in place upon the upper end of the burner, as shown,

by means of screw-threads, which is adapted,

when screwed downward, to bear upon the open end of the wick-tube, as shown in Fig. 4., and cut off the Iiow of gas therefrom, and when screwed upward to permit the '110W of gas from the wick-tube through the dischargeopenings, as shown in Fig. 3.` G represents a cup, secured to the burner in any proper manner, which is designed to hold a small quantity of gasoline. H represents a rim rising from the plate a, which is adapted to inclose the burner and concentrate the heat upon the desired point. of perforated metal or wire-gauze, which serves as a safety-shield to prevent the flame from reaching the tank, but which permits also the proper amount of air and draft to be supplied to the burner. J represents a hood of conical form, open above and below, which surrounds the burner, for the purpose of more eiectually mixing the gas and air, and also increasing the draft.

From. the foregoing description the operation of my invention will be readily under,

I represents a platestood. The smallcupG having been filled with gasoline and lighted, 'the heat resulting there` from will necessarily be comm unicated,through the burner, to the wick-tube. By means of this heat vapor is formed from the gasoline,

and this passes from the wick tube, down through the burner, outof the discharge-openings, into the shell e5. In this shell the gas is deiiected by the plate c, and thoroughly mixed with air drawn in from` below, the new mixture finally rising through the shell to the flame above, where it is consumed. Through the vent-tube, also, any gas that may accumulate in the tank is conveyed away tothe burner. When it is desired to discontinue the use of the stove the cap F is screwed tightly down upon'theopen end of the wick-tube, and

hence no gas or vapor can possibly escape.

Some ot the advantages of the described construction are as follows: The tank is so separated'from the heating-burner, although located` in comparatively close proximity to it, as not to be subject to its action, by means of which conditions of safety are obtained with economy' of space. By means of" the venttube the tank is relieved of" any gas that may accumulate, and also `the pressure of the atmosphere is utilized to cause the gasoline to flow to the wick-tube.

By the peculiar construction of the burner the gas and air are uniformly mixed and equallydistributed upon all sides.

By means of the plate F, for shutting olil the gas, the escape of smoke or vapor, after the extinguishment of the flame, is absolutely preven ted, and consequently no unpleasant smells result from this action. I

` By means ofthe lighting-cup lthe wick-tube may be heated and the gas formedwithout the production of smoke, as usually occurs in lighting this class of burners.

7. In combination withthe` tank, having a centralopening, the tube extending through the opening and the burner, the construction being such that air can risethrough the tank to the burner, as described.
