NEBULIZER.

SPECIFICATION formingpart of Letters latent No. 694,630, dated, March 4, 1902.

Application filed June 25, T90].

T0 ctZZ whom it may concern;

Be it known that LHERMANN GOLTERMANN, a citizen of the United States,residing in New York, borough of Manhattan, in the State of New York, have invented certain newand useful Improvements in Nebulizers, of which the following is a specification.

This invention relates to an improved neb ulizer or instrument in which a finer vapor is produced than in the well-known atomizers' by throwing the spray produced by an atomizing device against a wall, so that it breaks up into a vapor, and in which that part of the spray which liquefies on striking the wall is conducted back into the liquid vessel. Nebulizers have heretofore been supplied on the market, but the spray is produced at the-inside of the liquid vessel by striking against the sides of the same and is then conducted to the place of use. My invention is designed to produce the spray outside of the liquid vessel and conduct the same through a spherical or other head and a suitable nozzle to the place of use. For this purpose the invention consists of a nebulizer comprising a liquid vessel, a spray-head, and an atomizing device connected with the liquidvessel and at" ranged to spray the liquid against the sprayhead; and the invention consists, further, of certain details of construction and combina tions of parts, which will be fully described hereinafter and finally pointed out in the claim.

In the accompanying drawings,Figure 1 represents a side elevation of my improved nebulizer. Fig. 2 is a vertical longitudinal sec tion of the same, and Fig. 3 is a horizontal section on line 3 3, Fig. 2.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a vessel, of glass or other suitable material,in which the'liquid to be sprayed is placed. The liquid-containing vessel A is provided with a neck B, having an exterior screw-thread, on which is screwed the interiorly-threaded lower' end of a cap B, a washer 0. making the connection tight. The cap is provided with: a bore 12, which connects at its lower end with a suction-tube O and at its upper end with a spray-nozzle c, the end of which is bent over bores 17 in the cap B.

so that its end is above the end of the air- Serial- No. 65,922. (No model.)

7 supply tube d, which is connected by the bore cl and tube 01 with the ordinary rubber bulb D or other air-forein g device. The end of the air-supply tube 61 is located in proximity to the nozzle 0, so that by the air supplied under .pressure a suction is created on the liquid in the liquid vessel and the liquid raised through the suction-tube, bore 19, and nozzle and then atomized. On the upper end of the cap B is screwed a hollow head E, preferably spherical in'shape and provided with a discharge-nozzle e,which may be made integral therewith. The spray is thrown from the atomizing device against-theinner surface of the head E and is broken up by the same into an'extremely fine vapor, which escapes through the discharge-nozzle e to the part to be treated. The nozzle e is arranged at a slight inclination toward the head, so as to return into the same all liquid condensed therein when thenebulizer is set down. The liquid which condenses upon the inner surface of the hollow head E or is returned by the nozzle is conducted back into the liquid vessel by means of return- The air-supply tube is not connected with the vessel A, but with the spray-head, so that air under pressure is not supplied to the interior of the liquid Vessel, the liquid in the same being under-atmospheric pressure only.

My improved nebulizer has the following advantages: First, it is worked only by suction, no air, being supplied under pressure to the interior of the liquid vessel, but only supplied to the atomizing device at the atom izing -point; second, the surplus liquid is returned from the spray-head E through the return-openings 1) into the liquid vessel, so

that none of the liquid is wasted; third, the ,vaporis formed by the contact of the atomized spray with the inner circumference of the hollow head and then conducted off through 'the discharge-nozzle; fourth, the dischargenozzle being made in one piece with the hollow spray-head E and the latter tightly secured screwed on said neck, and provided with I head E screwed on said cap, the upperend of bores b extending through the same and communicating with the interior of the "essel, and with a liquid-supply bore 1) also extending therethrough, and an air-supply bore (,l', an air-supply tube d connected with said airsupply bore, and projecting from the upper end of said cap, a suction-tube 0 connected with the lower end of the bore 1), a nozzle 0 connected with the upper end of said bore and having its upper end bent over in proximity to said air-supply tube d, a spherical said nozzle and air-supply tube being located in the lower part of said head, and a discharge-nozzle projecting from one side of said spherical head, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
