ATOMIZER.

SPECIFICATION forming part of Letters Patent No. 533,489, dated February 5, 1895;

Application filed I'gbmary 12, 1894. $erial o. 49 9,892. (No model.)

To all whom it may concern:

Be it known that I, THOMAS EDWIN OGRAM, a citizen of the United States, residing at Washington, in theDistrict of Columbia, have invented certain new and useful Improvements in Atomizers; and I do declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable oth ers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in atomizers, and it refers more particularly to that class of atomizers, having a fluid receptacle or holder, an air controlling stopper, having connected therewith a sprayer, a storage bulb and a compression bulb, and such invention has primarily for its object to pro vide an atomizer of this character, which can be used either as a liquid or powder sprayer, in a simple, convenient and effective manner.

It has also for its object to provide an atomizer of this kind in which the stopper and its connected parts, including the air shifting valve devices are, very compactly arranged, and of a very simple and inexpensive construction; and which can be readily detached and replaced when it is desired to clean the same.

Furthermore it has for its object to provide an atomizer of this class in which the compression and storage bulbs, as well as the operating valve are so arranged, relatively, that it can be the more conveniently manipulated by the operator, and without danger of break ing any of the parts.

W'ith other minor objects in view, which hereinafter will be referred to, the invention consists in the peculiar and novel arrange ment and combination of parts, as will be first described in detail and pointed out in the claims, reference being had to the accompanying drawings, in which-- Figure l is a perspective View of my improved atomizer, the same being arranged as a powder sprayer. Fig. 2 is a cross section of the same on the line 2--2, of Fig. 3. Fig. 3 is a similar view of the same taken on the line 33, Fig. 2, the fiuid spray nozzle being shown inserted in dotted lines, and Fig. 4 is indicates a bottle or other holder for the fluid when the atomizer is used as a liquid sprayer, and as asupplemental air chamber when used as a powder sprayer, and B the stopper, which in the practical construction is formed of any desired material preferably of hard rubber, and of any desired shape or form. In the drawings such stopper is shown as cylindrical, in the form of a plug having a tapering extension Z) whereby it can be conveniently inserted in the mouth of the bottle, and such tapered portion may have an outer packing portion whereby it can be tightly fitted in such bottle mouth.

In the upper end, centrally, the stopper has a valve chamber 0, having an internal thread portion 0, which receives a screw cap D, which closes the upper end of such chamber and serves as an abutment for a spring 61, which bears down on and normally closes a valve E over an opening F, which communicates with the central air chamber G which extends vertioally down through the stopper, as shown, such valve E having its stem e projected down into such chamber, the lower edge terminating in a taper or needle bearing e.

At the front the stopper has a diagonally disposed aperture or chamber H open at the top, and communicating with the central chamber G at the bottom, such chamber forming the discharge or spray tube channel, as with it such spray tube is connected. In the construction shown a spray tube 1 having a short shank portion I is inserted in the upper end, which tube has at a point forward of its connection an orifice i in its top, in which fits a holder, having a tapering apertured upwardly projecting month i formed with a cork or other packing shell, whereby a bottle or other vessel can be fitted air tight into such month, as indicated in Figs. 2 and 4. When, however, it is desired to use the atomizer for spraying a liquid, the tube I is removed and a non apertured tube having an extension I is inserted, which passes down through the bottom of the chamber G as indicated in dotted lines in Fig. 3.

J, J indicate nozzle members formed at opposite sides of the stopper B, and projected at right angles to the front or spray tube channel, which have air orifices J, and J',respectively which discharge into the chamber 0 just under the cap D, and to one of such nozzles, J is connected the compressing bulb K while to the other J is connected the storage bulb K.

So far as described it will be readily seen that should the bulb K be compressed the air drawn in thereby will be forced through the nozzle J into chamber 0 and the storage bulb K, where it will remain as the valve E is held closed and the bulb K formed with the usual check valves (not shown).

In the rear the stopper has a valve chamber L projected at right angles to the nozzles J, J, the base of which has an aperture Z which opens into the chamber G and through which projects the stem m of a thumb operated valve M, which stem is wedge shaped or tapered at its end, normally projecting under the point of valve stem e as most clearly shown in Fig. 3.

As a simple and convenient means of adjusting and holding such thumb valve in place, such valve is provided with an annular flange m the outer edge m of which engages an internal annular flange on the centrally apertured screw plug N, while the inner face of such flange abuts a rubber cushion spring 0, which normally holds the button end of the valve M out to its normal position. By this arrangement of thumb valve, it will be readily seen that the valve E, can be opened to a degree proportionate to the pressure applied on the valve M, and in all cases owing to the taper of the stem m the rising of the valve E will be gradual. This result is very advantageous, as heretofore in atomizers of this kind, when the thumb valve is operated, the check valve would generally be thrown wide open. In the construction shown the escape orifice, under valve E can be regulated by the pressure of the thumb.

In operation after air is stored up in the bulb K, and it is desired to apply the powder by simply pressing on the thumb valve, the valve E will be raised and the air contained in the said bulb will pass down into chamber G, into the vessel up through channel H, and out through tube I, it drawing the powder from the bottle by induction as it passes.

In Fig. 4 I have shown a modified arrangement of the powder spray tube and air controlling devices. In this construction the storage bulb and the intermediate valve devices are dispensed with and the compressing bulb secured direct to such tube. In this construction as in the other the device is operated by one hand, leaving the other free for and the stopper with which they are connected, by means of tubes, said stopper having an air passage therein, a valve and its operating mechanisms, a spray tube connected with the air discharge passage, said tube having a nozzle or nipple intermediate its ends, and a powder bottle or holder supported upon said nozzle or nipple, substantially as shown and described.

2. An atomizer, comprisingaholder or main chamber, a stopper having a central chamber in its top, having oppositely extending orifices, a storage bulb, connected with one and a compression bulb with the other of such orifices, said chamber communicating with the holder and having a spring valve normally closing off such holder, a valve operating means operated from the outside, and a spray tube connected with the discharge channel of the stopper, all substantially as shown and described.

3. An atomizer comprising a holder, a compression bulb, a storage bulb, a chamber connecting such bulbs, having a removable top, and having an aperture in its bottom communicating with the holder, a spring valve, normally closing such aperture, and having a shank extended through the aperture, a push valve having a tapering end adapted to engage such valve stem, and the spray tube and discharge channehall arranged substantially as shown and described.

4. The combination in an atomizer, of a holder, a stopper closing the mouth thereof, having a chamber in its top, having a removable cap, and nozzles projected through the opposite sides of the stopper, a discharge chamber, having a connected spray tube, an opening connecting such discharge and the top chamber, a second chamber projected rearward at right angles to the first chamber, a thumb valve held to operate therein, having a tapered end, and a spring actuated valve held to operate in the upper chamber and having a stem held to engage the stem of the thumb valve, all substantially as shown and described.

5. The combination, in an atomizer of the kind described with the shifting valve, between the bulb discharge orifices of a cham her having an apertured screw cap having an internal annular flange, a thumb valve having a button projected through the cap and formed with a flange abutting the cap flange, said valve having a stem held to engage the shifting valve, and a spring held about the thumb valve to normally force it to its normal position, substantially as shown and described.

In testimony whereof I afifix my signature in presence of two witnesses.

THOMAS EDWIN OGRAM.
