1 Claim. (01. 26178) My invention relates to improvements in vaporizers for mixing air, or gas, with liquid to form vapor The principal object of the invention is to provide a vaporizer which embodies a discharge constructed and arranged to break up the liquid Figure 1 is a view in side elevation of my improved vaporizer, and

Figure 2 is a view in longitudinal section.

Reference being had to the drawing by numerals, my improved vaporizer, in its preferred embodiment, comprises i8, spherical bulb I forming a liquid container. A jet-type nozzle 2 is fitted into and fixed in a. suitable aperture 3 provided in one side of the bulb I. The nozzle 2 comprises a tapered discharge end 4 projecting radially into the bulb I, and a right angled tapered end 5 outside the bulb I for attachment to the usual compressible air bulb, or an air or gas pressure line, not shown. A small diameter siphon tube 6 is mounted in the bulb I preferably radially of the same and in a common plane with the nozzle 2, at a right angle to the axis of the discharge end 4 of said nozzle to provide an intake end I spaced slightly from the inner circumferential wall of the bulbI and discharge end 8 laterally offset from the axis of the discharge end 4 of nozzle 2 and directly in front thereof. A discharge tube 9 extends from the bulb I' and opens into the latter diametrioally opposite the discharge end 4 of the nozzle 2. Preferably, although. not necessarily, the discharge tube 9 is straight and of substantially uniform diameter. The mounting for the siphon tube 6 comprises an arm I9 extending from the discharge end 4 of the nozzle 2.

The discharge tube 9 is provided with a plurality of internal bafiles II spaced longitudinally along said tube and circumferentially thereof and which preferably have the form of inwardly tapering protuberances extending radially inwardly of said tube past the axis thereof. The baffles II may be arranged in pairs extending from opposite sides of said tube and spaced apart longitudinally in the tube or otherwise as desired. Also, said baiiles I'I may be spaced as close I together as may be found desirable.v

As shown, the bulb I, dischargetube 9 and baffles II are formed ofglass and in one piece. There may be as many baffles as may be found suitable in vaporizing different liquids and prefierably said baffles II are circular in cross see- In the operation of the device, liquid is introduced into the'bulb I by way'of the discharge tube 9 to fill the bulb, for instance, a quarter full. With the device positioned so that the intake end of the siphon tube 6 is lowermost and submerged in the. liquid, if air, or gas, under pressure is permitted to discharge into the bulb I from the nozzle 2 over the discharge. end of the siphon tube 6 such air or gas will cause a siphoning of liquid upwardly through the tube 6 to be mixed with the air or gas and form a spray therewith which will be directed in jet form directly into the discharge tube 9 and forcedthrough the sameunder pressure. The liquid contents of the spray will be impinged againstthe baffies II and broken up into finely divided form and the larger droplets, or particles, not immediately broken up will collect on the baffles II to be subsequently atomized and picked up so that the resultant discharge is a, mist-like vapor the liquid contents of which are more finely divided than can be accomplished with the'usual liquid'vaporizing devices of commerce.

The foregoing will, it is believed, sufiice to impart a clear understanding of my invention without further explanation.

Manifestly, the invention, as described, is susceptible of modification without departing fromthe inventive concept, and right is herein reserved to such modifications as fall within the scope of the subjoined claim.

What I claim is:

In a vaporizer, a bulb-like liquid container, at discharge tube extending from one side of said container, means to vaporize liquid in the container and inject the vapor into said tube and force the same therethrough, and baffle devices in said tube for breaking up the liquid contents of the vapor passing through said tube, said means comprising a nozzle projecting radially into said container from the side thereof opposite the dis-
