No. 643,0I4. Patented Feb. 6, |900. C. A. TATUM.


(Application led Sept. 21, 1899.) (No Model.)



SPECIFICATION forming part of Letters Patent No. 643,014, dated February 6, 1900.

Application filed September 21, 1899. Serial No. 731,159. (No model.)

To a/ZZ whom it may concern:

Be it known that I, CHARLES A. TATUM, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Atomizers, of which the following is a full, clear, and exact description.

Myinvention relates to atomizers, and more particularly to atomizers adapted for use in ro treating the throat or nose. It sometimes occurs in using ordinary atomizers that drops of the liquid or material employed will be forced from the atomizer into contact with the part treated-such as the throat, for instance. When nitrate of silver or other caustic substance is employed, it is essential that the material be applied to the part treated in the smallest possible divided particles or in the form of mist and that no large particles 2o or drops of material will rcachcontact with the throat or other part treated to unnecessarily burn or injure the part.

The object of my invention is to provide a simple, cheap, and eiicient atomizer, orwhat z5 I term a nebulizer, which will overcome the disadvantages above pointed out and in which the parts maybe readily disconnected and cleaned.

To these ends my inventionconsists in an 3o atomizer embodying the novel arrangement and combination of parts to be hereinafter described and claimed.

In the accompanying drawings, Figure l represents a side view, partly in section, of

one form of atomizer embodying my invention, the section being taken on the line l l of Fig. 2. Fig. 2 is a top View of the same with parts broken away and the atomizingchamber removed.

The atomizer may be said to consist of four parts-t'. c., the receptacle A for containing the material to be used, the mounting B, which comprises the atomizing parts, the atomizing-chamber C, and the bulb D.

The receptacle A may be of any desired form or construction, but is preferably made of glass and is provided with means for securing the mounting B thereto-such, for instance, as the screw-thread a, which coperates with the corresponding screw-thread b on the mounting, a washer c-being interposed between a suitable lan ge on the mounting and the receptacle A.

The mounting B comprises a substantially cylindrical body portion d, which is open throughout t-he interior thereof, as indicated at e, so as to establish open communication between the interior of the receptacle A and the atomizing-chamber C. Projected through and carried by a side wall of the body cl is 6o an outlet-tube f, that is substantially U- shaped throughout aportion of its length, the inner end of the tube being centrally disposed in the body d and adapted to project into the closed atomizing-chamber C when the latter is secured to the mounting B by the screw-thread g.

The chamber C is preferably made of glass and. is perfectly of substantially pear shape, and it will be observed that the only opening 7o in the chamber C is that which communicates with the mounting B. Secured to and depending from the outlet-tube f is the fluid conveying or supply tube h, which extends into the receptacle A and projects above the inner open end of the outlet-tube. The atomizing-tube i is projected through and secured to a Wall of the body d and extends up adjacent to the outlet-tube and to the fluid conveying or supply tube h, to both of which the 8o atomizing-tube may be further secured, if desired. The outer end of the tube h may be provided with the usual nipple, to which the bulb D or the connecting-tubej may be attached. The liquid or material to be used is first placed in the receptacle A, and the parts being united a compression of the bulb D will cause the material to be atomized within the chamber C. Compression of the bulb will 9o fill the chamber with the atomized products, which by the internal pressure will gently force said products through the outlet-tube in a ne mist. It will be observed that the outlet-tube is so constructed and positioned in the atomizing-chamber that only the finest mist can pass therethrough and that this mist is gently expelled from the tube. Any drops or large particles of the material which might by any chance be ejected from the supplytube h cannot pass through the outlet-tube, but will be conveyed back into the receptacle IOO A, together with any of the atomized products Which liquefy Within the chamber C.

It Will be seen that the parts can be readily disconnected and cleaned and that the atomizer being constructed principally of glass enables the user to carefully inspect the construction Without disconnecting the parts.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In an atomizer, the combination of a containing-receptacle, an atomizer-mounting removably secured to said receptacle and constituting the means forsupporting the atomizing parts and an atomizing-chamber independent of the containing-receptacle, said chamber being carried by and removably secured to said mounting, and the only opening therein being the one which communicates with the mounting there being open communication through the mounting between said atomiZing-chamber and the receptacle, whereby the atomized products will pass from the chamber through the atomizer-outlet and the liqueiied products will pass back into the receptacle.

2. In an atomizer, the combination of a containing-receptacle, an atomiZer-mounting removably secured to said receptacle and carrying een trally-located atomizing supply and outlet tubes, said last-named tube being substantially U -shaped for a portion of its length and a closed atomizing-chamber carried by and removably secured to said mounting and into which the said atomizing supply and outlet tubes are adapted to project, there being open communication through the mounting between said atomiZing-chamber and the receptacle, whereby the atomized products will pass from the chamber through the outlet-tube and the liquefied products will pass back into the receptacle.
