ATOMIZER-VALVE.

SPECIFICATION forming part of Letters Patent No. 554,432, dated February 11, 1896. Application filed July 18, 1895. VSerial No. 556,343. (No model.)

To all wwn/L it may concern.-

Be it known that I, WILLIAM l-I. WIGMORE, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Atomizers, of 'which the following is a specification.

My invention relates to improvements in atomizers, and more particularly to improvements in that class of atomizers which are used for medical purposes, and in which the compressed air or gas which forces the liquid out of its retaining-vessel in a spray is contained under pressure in a tank, and which is conducted, as required, to the liquid-containing vessel, the object of my invention being to furnish an inexpensive and efficient device by means of which the iiow of compressed air or other gas to the liquid-containing vessel may be perfectly controlled and the spray therefrom instantly checked at any moment.

In the accompanying drawings, forming part of this specification, and in which similar letters of reference indicatesimilar parts throughout the several views, Figure l is a central longitudinal sectional elevation through my atomizer-valve, the vessel containing the liquid to be sprayed being shown partly in side and partly in sectional elevation; Fig. i?, partly a side and partly a central longitudinal section through the stemy of my atomizer-valve; Fig. 3, a plan of partition in the lower part of the valve-casing, and Fig. 4 a section of Fig. 3 on line X X.

A is the vessel for containing the liquid to be sprayed; B, a stopper in the mouth of vessel A; C, a spraying-tube of the usual con? struction, which passes through stopper B.

D is a valve-casing, the upper end of which is closed by a cap E, which contains a stuffing-box F, through which passes the valvestem G, and the lower end of which is closed by a cap I-I, from which projects a nozzle I, which is adapted to be forced into and held by the projecting walls J of an orifice opening into spraying-tube C. K is a partition near the lower end of valvecasing D; L L, tubes passing through this partition and through the valve-seat M.

N is a disk, of rubber, leather or other suitable material, carried by the lower end of valve-stem G, which is adapted to close the opening O in valve-seat M when the atomizer isnot in use.

P is a stop adapted to be screwed onto the lower end of valve-stem G, in order to hold disk N in place.

R is a collar carried by stem G; S, a spring, one end of which bears against valve-seat M and the other against collar R.

T is a thumb-piece carried by outer end ofvalve-stem G; II, an adjustable stop carried upon the outer end of valve-stem, which is threaded in order that this stop may be moved in or out to permit the valve to be opened to a greater or less extent.

V is an opening connecting with interior of valve-stem G, the outer end of which is hollow, as shown.

W is a nipple screwed to a iianged opening in the lower part of the valve-casing D; X, a tube connecting nipple W with the airtank. (Not shown.)

Then it is desired to operate the atomizer the inger or thumb is placed upon-the thumbpiece T, closing the opening Y in this thumbpiece, which connects with the hollow valvestem G, the valve-stem is forced inward and opening O in valve-seat M is opened. Airnow passes from tube X through nipple lV to interior of valve-casing D, up through hole O, down through pipes L to nozzle l, thence to vessel A, and forces the liquid from this vessel in a spray through the nozzle of pipe C. When it is desired to stop the spray the thumbpiece T is relieved. The spring S now forces stem G outward, the valve O is closed and the air which is under pressure in vessel A in stantly passes up tube C, through nozzle T and pipesL to the upper or outer end of the chamber formed by the valve-casing, into oritice V, and through hollow valve-stem G to the air. Thus the pressure in vessel A is instantly relieved when valve O is closed, and the spray from the nozzle of pipe C stopped simultaneously with the shutting off of air from air-tank.

For the sake of clearness I have shown in Fig. l of my drawings the pipes L moved ninety degrees out of their actual position. In practice they are placed at right angles to the position. shown in order to permit me to assemble the parts of the device. It will be seen that the head P of the valve-stem and IOO the washer N have to be placed on the valvestem after this latter has been passed through opening O in valve-seat M. I pass them through the flan ged opening, to which nipple W is screwed, and then secure them to the valve-stem, and in order to permit this the pipes should be placed so as to allow them to be easily entered.

Vhile I have described my atomizer in connection with a tank for storing air or gas under pressure, it will be understood that I do not desire to confine myself to the use of this tank, as the bulb used in many forms of atomizers may be used as the source of air-supply.

Having thus described my invention, I claiml. The combination in an atomizer of a vessel for containing liquid7 a spraying-pipe connected with said vessel., an air-supplying device, a valve intermediate between said airsupplying device and said vessel, by means of which the flow of air to said vessel may be controlled a valve-stern, and an opening in said valve-stem adapted to be operated by the finger, through which the pressure in said vessel may be relieved when said valve is closed.

2. The combination, With an atomizer, a

valve-casing, a valve-seat and valve within said casing, a spring for keeping said valve normally closed, a valve-stem, an opening in said valve-stem adapted to be operated by the finger, a chamber in said valve-casing, in which said valve works, and which is connected with the air-supply, and airducts forming a communication with the spaces within said casing, at each side of said chamber.

3. The combination, with an atoinizer, of a valve-casing, a valve-seatand valve within said casing, a partition within said casing, forming a chamber within which said valve works, means for connecting said chamber with the air-supply,pipes passing through said casing and valve-seat, a hollow valve-stem, an opening connecting the interior of said valvestem with the interior of the casing above the valve-seat g a spring for normally closing said valve, a cap and stuiiing-box for closing the outer end of said valve-Casin g, and a cup and nozzle at the inner end of said valve-casing.
