UNiTED TATES ASAHEL M. SHURTLEFF, OF BOSTON, MASSACHUSETTS.

ATOiVllZER.

EPECIPICATION forming part of Letters To aZZ whom it may concern:

Be it known that I, ASAHEL M. SHURTLEFF, of Boston, county of Sulifollr,a11d State of Massachusetts, have invented an Improvement in Atomizers, of which the following description, in connection with the accompanying drawings, is a specification, likeletters on thedraw ings representing like parts.

This invention has for its object to construct an atomizer which may be more cheaply made, more efficient in operation, and more durable; and the invention consists in many details of construction, to be hereinafter pointed out in the claims at the end of this specification.

I wish to state at the outset that while I have shown and described herein the following mat ter-namely, a liquid-holding jar, a cap or stopper therefor, and inlet and outlet tubes, combined with a tubecommunieating with the inlet-tube and bent at its lower end toward the wall of the jar to form an offset, and atomizing-nozzles arranged upon the offset portion of the said tube to direct the spray against the opposing wall of the jar, I do not claim the same specifically, but reserve it for my application for patent, filed November 21, 1887, Serial No. 255,757.

Figure l shows,in side elevation and partial section, an atomizer embodying this invention, and Fig. 2 a vertical section of the cap or stopper.

The bottle a has a screw-threaded neck, a, and an annularly-grooved bottom, a A metal cap, or, provided with screw-threads is made to fit the screw-threaded neck of the bottle. The cap has fitted into it ahard-rubber or other anti-corrosive plate, at and a soft-packing washer, a the said washer bearing upon the upper end of the neck of the bottlea when the screwcap is turned upon the bottle, such cap serving, in the present instance, as a stopper.

The hard-rubber or anti-corrosive plate is cut of suitable size to snugly fit the cap a and the plate having been placed within the cap the latter is screw-threaded, the pitch of the thread being sufficient to form an annular groove to receive and hold the plate. The cap a is provided externally with a nipple or plug, a (see dotted line) upon which is sprung a flexible tube, a having a suitable mouthpiece, a". A tubular coupling, a is soldered or otherwise attached to the cap a, the said Patent No. 379,611, dated March 20,1888.

Application filed December 15, 1886. Serial No. 220,611. (No modell) coupling being tapped to receive the air-tube c, which passes up ward through the hardrubthe bottle, said coupling a projecting sufficiently beyond the edge of the cap or stopper to serve as a handle by which to facilitate removing the cap.

The air-tube c is bent outward intermediate of its length to pass downward along the inside of the bottle, and it is provided at its lower end with the atomizing nozzles or orifices 2 3, arranged in usual manner with rela tion to each other, the liquid-tube c, which receives the nozzle 2,'being made or molded in tegral with the air-tube c, and just above the exits of the atomizingoriiices 2 3 a suitable guard, 0 projects,which is also made integral with the piece containing the air and liquid tubes, such a guard serving to protect the ends of the atomizing nozzles or orifices, preventing the said nozzles from striking the interior of the neck and shoulder of the bottle when the said tubes are removed.

Making the air and liquid tubes 0, guard 0", and bearing for the atomizing-nozzles 2 in one piece greatly strengthens and also cheapens the construction, and by bending the tubes outward, as described, the atomized liquid blown or forced from the tube and beaten into spray has a much greater distance to travel be fore striking the hard or com minuting surface at the opposite side of the jar, which in turn again acts to beat the sameinto finer particles, completely filling the jar with the spray and forcing it outward through the flexible tube a and mouth-piece a.

In practice it has been found that the greater the distance the atomizing-tubes are located from the hard striking-surface the finer the particles of spray. The air is forced by a suitable air-pump, A, into the receiver A, and from thence it passes through the tube 1) to the tube 1), through the air-filter b", of any usual construction, which is attached to or fitted into the tubular coupling a The tubes 1) b are joined by a controlling air cock or valve, d, provided with a valve stem, which, when pressed, opens the port, admitting air to the tube 1), so that the receiver A can be filled with air under quite heavy pressure and the patient can admit the air to the jar as suits his convenience.

ber plate a and downward to the bottom of It is obvious that, instead of employing the air pump and valve, an ordinary bulb and flexible tubecommon to atomizers may be employed, and also, if desired,the airfilter may be removed.

It has been found in practice that by forcing the air through long flexible tubes particles of the substance forming a part of the rubber compound, as sulphur, for instance, and other foreign material, are conveyed into the air-tube a, checking the passage of air through the nozzle 3, and by providing the air-filter, as shown and described, this ditficulty is obviated. The air-filter also serves to arrest dust and disease-germs, if any are contained in the air of the room, and while the location herein shown for the filter is most effectual, I do not herein desire to limit myself to any particular location.

I do not herein specify any particular construction of filter, but'I prefer to employ one containing a piece of wire-gauze supporting a small amount of cotton.

The annular groove aflinto which the lower end of the bent tube 0 enters, having small holding capacity, but large in vertical area, admits of great economy in the use of medicines when'used in connection with the tube herein described, and instead of making the groove entirely around the lower portion of the bottle a small cavity or well may subserve all the requirements.

I am aware that it is old to make an atomizer comprising a liquid-holding jar and acap I or stopper therefor, and a liquid and air tube constructed in a single substantially straight stem and jet-orifices located at a point between the ends of said substantially straight stem.

I claim 1. In an atomizer, the j ar a and cap therefor, to which are attached the air-tube c and outlettuhe a, combined with a hard-rubber plate, (2*, having a screw-threaded hole to receive the upper end of the air-tube c, and a soft-packingwasher, a, resting against the rubber plate a, 5 substantially as and for the purpose described.

2. In an atomizer,,a jar, a, and cap or stopper therefor, combined with a tube having at its lower end the atomizing nozzles or orifices 23, and a guard, 0 to protect the said atomizing-nozzles, substantially as described.

3. In an atomizer, the jar or and the cap or stopper therefor,to which the inlet and outlet tubes are attached, combined with the tube 0,

bent-to conform to substantially the outline of 5 the body of the jar and having the end portion 0', constructed integrally with thenozzle 2, substantially as set forth.

4. In an atomizer, thejar a and cap or stopper, combined with the tubular coupling a, secured directly to the cap or stopper, and an air-tube located within the jar and attached to the tubular coupling, said air'tube having at its lower end the atomizing-nozzles.

5. The atomizing exit-orifices and an air- 6 duct leading thereto, combined with an airfilter through which the air passes previous to passing through the atomizing exit-orifices, substantially as described. I

6. The'jar a, containing the atomizing-noz- 7o zles and the outlet and inlet tubes connected with the jar a, combined with an air-forcing apparatus and a cut-off or controlling valve controlling the passage of air to the jar a, said valve consisting of a valve case and seat, and 7 a plunger movable in the direction of the length of the valve-case, substantially as described.

In testimony whereofI have signed my name to this specification in the presence of two sub scribing witnesses.

ASAHEL M. SHURTLEFF.
