i Beneath therboilerand in a supporting ,relation f thereto is; a cylindrical` receiver 6 @for a liquid `oa disinfectant lor `any other ydesired nature, which is t'obe discharged to the atmosphere `bygthe `atom- `izer, `1in thexformofa'nespray. ,l 4SaidV receiver 4is l of lsubstantially the samediameter as #the boiler,

and is equipped withy an upturned'llingfc neck 1',

. which projects radially somedistance beyond the ush exteriorjwallsof ,thelbo'ilerl :and receiyr, andislnormallyfclosedi by a screw plug 8 or the like. .The bottom o f the boiler is sphericallyigupf Wardly` dished, `thereby increasing its resistance `to steam` pressure andiforming agspace above the receiver,- -substantially coextensive with the top face'fthereof, `which mayV receivea -heat insulating `packing-,9. This packing` ispreferably asbestos,

which is applied in awet orpulpy state,` thenboiler and receiver being-i pressed together l to compress `said packing. When the latter dries and h ardens,`

it adheres strongly to both the boiler and .receiver I and thus :acts as a securing means tdmaintain the describedassembled,V relation oft` said-parts.-yA .f

t Said assembly isfurther stronglywmaintained by. aheat insulating jacketV I0, which` snuglyeznT braces fboth* the :boiler `and receiver, extending substantially the full height of theatomizer, conforming -to the reducedupperportion ofthe boiler "andsmarginally ...embracing the cover. `2. Said` jacket l'preferably comprises` aninner `layer y Illa; a

ofllat sheet4 asbestos, `which is preerably glued Lor otherwise. firmly secured to the receiv 'er,-, fb oiler,` .andI cover,` 2. `Surrouriding said? layer isa thick'- ness lof vertically fcorlllgaiedlsheet asbestos IQbg and about this is applied a thickness Ic of vertically corrugated, heavy paper, and there may be finally applied if desired, a thickness of paper or other sheet material Id, colored to imitate leather or to impart any other desired finish. To bind said jacket very securely in place upon the boiler I, receiver 6, and cover 2, it is preferred to tightly engage the jacket by three metal bands I I, preferably aluminum, jointly clamping the jacket firmly upon eachof the specified parts.

Mounted upon the cover 2 of the boiler above the margin thereof is an atomizing head |21 (see Fig. 2), which is preferably cylindrical and comprises an inlet member I2a and an outlet member 12b, said members being in screw-threaded engagement. The opposed end faces of the members I2a and I 2b are formed respectively with a conical projection I3 and a conical recess receiving said projection and having a vapor outlet I4 v at its apex. The projection I3 is spaced from the wall of said conical recess to form a suction chamber I 5. To support the head I2 and deliver steam thereto from the boiler, a short length of curved metal tube IB is at one end rigidly mounted upon the cover 2v and opens through the latter, its other end being axially inserted in the member I2a and communicating with a passage Il aligned with and opening toward the outlet I4.

For delivering liquid to said atomizing head from the receiver 6, a flexible metallic tube I8 extends from said receiver to said head in heat absorbing relation to the boiler. The lower end portion of said tube extends into said receiver through `a fluid sealed opening, having a terminal inlet adjacent to the receiver bottom, and in extending upward frorn the receiver, thetube passes between the boiler and heat insulating jacket. The heating effect of the boiler upon the liquid discharging through the tube may be increased to a desired extent by spiraling the tube around the boiler, as is clearly indicated in Fig. 1. The upper end of the tube I8 is inserted eccentrically inthe member I2a of the atomizing headthrough which the liquid is delivered to the outer portion of the suction chamber I5.

An 4electric heater I9, of Vany suitable construction, is positioned in the lower Aportion of the boiler, and may be mounted in a vertical wall of the boiler, through which a threaded portion 20 of said heater projects outwardly for engagement by a clamping nut 2|. It is preferred to mount on said portion, exteriorly of the boiler, a fusible member 22 which lies in the circuit of the heater and is subject to the heat generated by the heater, said'member beingadapted to melt when the' heater temperature vrises materially above the boiling point of water. Thus Amelting of said member will automatically break the heater circuit in case the supply of water in the boiler becomes ,sov depleted as to leave the heater uncovered.

In operation of the invention, upon energization of the heater, the temperature of water in the boiler is soon raised to the boiling point, and steam is discharged from the atomizing head, drawing up a flow of liquid from the receiver 6 through the tube I8, and said liquid discharging with the steamin a finely vaporized form. The location of the atomizing head adjacent to a margin of the cover 2, and the arrangement of said head to discharge above and across said cover utilizes the rise of heated air from the boiler toA `resist any tendency toward dripping of` liquid from the atomizing heador downward spattening of liquid particles from the spray.

The insulating jacket I0 conserves heat in the boiler and receiver and further permits the atomizer to be manually held, while in use, Without resulting discomfort. Also said jacket serves to strongly hold the boiler and receiver in proper assembly and to secure the cover 2 in place.

Because of the location of the atomizing head adjacent to the margin of the cover 2, and the direction of discharge from said head toward the axis of the atomizer, any such tilting of the atomizer as is required to give a downward direction to the discharging spray will still maintain the point of steam discharge from the boiler uppermost and insure against water delivery from the boiler to the atomizing head.

The described composite heat insulating jacket has been found highly eiiicient both in resisting heat transmission and in supplying adequate strength to strongly hold the engaged parts in assembly.

The invention isl presented as including all such modifications and 'changes as properly come within the scope of the following claims.

What I claim is:

Y

3. In a `steam pressure atomizer as set forth in claim 2, the bottom of said boiler being upwardly dished and thereby forming a space above said receiver, heat insulation in said space.
