SPECIFICATION forming partrof Letters Patent No. 437,569, dated September 30, 1890. Application led March 18, 1890. Serial No. 344,393. (No model.)

` To all whom it may concern.-

Be it known that. I, ROBERT W. COFFEE, a citizen of the United States, residing at Bedford Oity, in the county of Bedford and State of Virginia, have invented a new and useful Atomizen of which the following is a specifi cation.

This inventionv has relation to atomizers;

whereby the vapor may be directed to any suitable point in a compartment in which it is used.

Other objects and advantages of the invention, together with the novel features thereof, will hereinafter appear, and be particularly pointed out in thev claims.

Referring tothe drawings, Figure 1 is a side elevation of an atomizer constructed in accordance with my invention. Fig. 2 is a central longitudinal section. Fig. 3 is a detail in perspective of the atomizing chamber or tip.

Like numerals of reference indicate like parts in all the figures of the drawings.

In practicing my invention I employ a globular steam-chamber 1, swelled at its center and provided at one side' with an annular steamdischarge 2 and at its opposite side with a threaded opening 3, and intermediate the two diametrically-opposite openin gs 2 and there is provided a threaded neck or opening et. The opening 2 has its inner surface reduced to form an inclined seat 5.

6 represents the cylindrical atomizing tube or tip, which is mounted within the globular chamber 1 and provided at its rear end with a circular base 7, above which there is formeda series of screw-threads 8, which mesh with similar threads formed upon the inner surface of the opening 3, the base 7 snugly fitting against the rear end or mouth of the opening, and the opposite end of the tube 6 is conical and agrees in shape with the inner annular surface or 'wall 5.

The cone-shaped end 8* of the atomizer is provided with an annular series of orifices 9, the exterior of the atomizer being provided with a series of tapered and converging grooves 10, leading from each of the orifices to the apex of the cone.

The base 7 of the atomizin g-tube is provided with a threaded opening 11, and is connected to an elbow-pipe 12 by a threaded collar or coupling 13. The opposite end ofthe elbow 12 is similarly connected by a coupling 14 to a flexible tube or hose 15, connected .at its opposite end with any suitable water-supply. (Not shown.) The neck 4 of the chamber 1 is `by a coupling 16 connected `to the end of an elbow-section 17, and the lower end of said section is by a coupling 18 connected to one end of a valve-chamber 19, having a valve-seat 20, in which operates a valve-plug 21,aftixed to the inner end of a threaded valve-stem 22, mounted for movement in a guide .23, and provided at its outerend with an operating-wheel24. To the opposite end of the valve-chamber there is connected a rigid pipe-section 25, the opposite end of which connects with a nexible hose-section 26.

Surrounding the pipe-section 25 is a Wooden hand-hold 27, or, if desired, said hand-hold may beconstructed of an yother suitable heatnon-conducting material.

The device is grasped by the hand of the operator, aid may thus be convenient-ly directed in any desired direction. The pipe 26 is connected with any suitable steam-supply, and by operating the valve 24 so as to be withdrawn from its seat a supply of steam passes through the pipe 26 and the valve into the globular chamber 1, and is discharged in an annular jet from the space formed by the conical seat 5 of said chamber and the coni-l cal tip at the end of the atomizing-tube, said jet following the contour of the tip and caus,

ing a vacuum within the tip and the watersupply pipe. This draws water from the supply and from the perforations or orifices 9 and thoroughly vaporizes the same, thus inipregnating the steam with its moisture.

The efliciency of this device willbe readily apparent, and also its simplicity ot construction and cheapness. It is also apparent that by proper manipulation of the valve the quantityof steam ,may be carefully regulated, so as to practice economy in this respect.

The atomizer herein describedv is particularly adapted for use in ordering tobacco, wherein it is necessary that an exceedinglyheavy steam be discharged, and also that the IOO same be freed as much as possible from its caloric properties. The objectof thus reducing the temperature of the steam when used in ordering tobacco is to prevent, as far as possible, any heating of the leaf, which, as is well known among those conversant with ordering tobacco, causes a closing of the cellular tissue of the tobacco, and thus prevents the same from thoroughly absorbing the moisture within the drying-chamber. It is therefore highly desirable to discharge an exceedinglyheavyvapor and at the same timea comparatively cool one, which I accomplish by theinvention hereinbefore set forth.

It is apparent that by operating the circular base 7 of the atomizing-tube the steam-` jet may be regulated, in that I may enlarge or ensmall the annular space surrounding the tip 8.

Having thus described my invention, what I claim is- Y 1. vIn an atomizer, the combination, with al globular steam-chamber 1, provided with a discharge-opening 2 and with a water-inlet 3 and with a steam-inlet 4, of a steam-pipe connected with a steam-inlet, an atomizing-cyl inder mounted in the chamber and having a perforated discharge end projecting beyond the discharge end of the chamber, and a water-supply pipe connected with said cylinder, substantially as specified. 2. In .an atomizer, the combination, with the n 'chamber l1, having the conical opening .2, of the cylinder 6, mounted in the chamber and having the conical tip 8*, mounted in thej opening 5 and provided with a series of orices 9, each having a groove 10 disposed to- Ward the apex of 'the cone of the tip, substantially-as specified.

3. In an atomizer, the combination, with the globular chamber 1, having the diametricallyopposite openings 2and 3, .the form er reduced,

as at 5, and between said openings provided with the neck 4, of thecylinder 6, having the reduced conical tip 8*, perforated, as at 9, and

mounted in the chamber, the elbow-,section a valve, and the coupling 18, for connecting the elbow-section and chamber, the rigid tube 25, connected with the chamber, the flexible `tube 26, leading from any steam-supply connected with the rigid tube, and the heat-nonconducting hand-hold 27, mounted on the tube 25, substantially as specified.

4. In an atomizer, the combination, with a globular steam-.chamber 1, provided at one end with a conical discharge-.openingpZ and at its other end with a water-inlet 3, and between the two with a steam-inlet 4, of an atomizing-cylinder 6, mounted in the steamchamber and having a perforated .conicalend 8* inserted through the conical ,opening 2 in the chamber and projecting beyond :the same, and having its rear end mounted .in .the Water-inlet 3 of the chamber, a water-.supply pipe connected therewith, and a steam-pipefconnected with the steam-inlet4 of the chamber,

said conical end of the atomizer-.cylinderhaving la series of grooves 10 leading Vfrom the perforations toward the apexof thceone, substantially as specified.

-In testimony that I claim the foregoing as my own I havehereto aflixedmy `signature in presence of two witnesses.
