I tube 9 at opposite points.

trance of liquid into the tubes an outer vaporizing siding at Detroit, in the county of Wayne and. tate of Michigan, have invented certain new and useful Improvements in Atom- '1zers, of which the following is a specification, reference being bad therein to the ac- In atomizers or nebulizers of ordinary type so far as known to me there is no provision for preventing entrance of liquid into the spray tubes and more especially is this true in instruments of this sort designed for the ocket.

-T is invention relatesto an atomizer having special provision for checkin the eualso for providing a very large volume of spray in pro ortion to the amount of medicament u as well as to certain features which protect the packing from contacting with the contents.

The invention 'consists in the matters hereinafter set forth and more particularly inted out in the appended claims.

In the drawin s, Figure 1 is a view in elevation in exten ed position of an atomizer embodying features of the invention. Fig.

2 is a view in longitudinal section thereof.

Fig. 3 is a view in cross-section VflfiOl'lZlIig tube.

eferring to the drawings, a cylindrical through a a reservoir 1 has a removable nozzle 2 of appropriate shape frictionally engaging a lateral apertureinear the base of the reservoi which opens. at about the axial center into an outlet tube 3 extending well up toward the top of the pylinder. mouth4 of the outlet tube is outturned laterally and bellshaped. A hollow capo rovided with a tubular flange 6 is screw-t readed into the to of the reservoir 1 and has a lateral rim 7 which acts as a retainer'for a soft packing ring or asket 8. An air tube 9 removably secured suitable means in the cap 5 extends well into the bodyof the cylinder. An tube 10 is concentrically secured on this air tube 9 the preferable construction bein 'that indicated wherein the outer tube 10 1s flattened to grip the inner Spray apertures 11 formed in the sides of the two tubes, which are open at the ends, complete the vaporizing means.

' compression cylinder.

agement with the cylinder 1, an 1nner 'annu ar flange 13 at its lower end acting as a-sto against the shoulder 14 formedon the cy inder 1, and a spiral spring 15, which is tapered so as to close noiselessly, is in compression between the reser V011 cap 5 and a detachable head 16 on the I A packing disk 17' confined by the head 16 against the cylinder end has a'central tongue or flap 18 acting as a valve against the central aperture 19 on the head, a hollow boss '20 with air inlets 21 admltting air to the cylinder through this valve. A lug122 at the lower end of the reservoir is'a apted to pass through a suitable slot in the retaining flange 13 of the compression cylinder 12 so that the latter may be given .a part turn and locked in compressed position for carrying in the pocket.

One quantity of vapor produced when using tie double tubes, in proportion to the small amount of medicament in the reservoir.

Another feature is the shape of the cap for the reservoir which prevents contact of the reservoir contents with the packing.

Another very important detail is the arrangement of the tubes which prevents escape of liquid through the spray nozzle when the atomizer is being carried in the pocket.

Obviously, changes in the details of construction may be made without departing from the spirit of the invention, and I do not care to limit myself to any particular form or arrangement of parts.

What I claim as my invention is:-- o 1. An atomizer comprisin a cylindrical reservoir permanently close at its lower end, an outlet tube extending from the lower telescopical en end u ward in. the reservoir and having a latera ly turned bell-mouth upper end, a nozzle extending laterally from the lower end of the reservoir that 1s connected by an aperture in the reservoir base with the outlet tube, a hollow cap detachably secured in the upper end of the reservoir, 'a' packipg ring secured on the cap by an annular run thereon, an air tube 0 ening through the cap extending toward t e lower end of the reservoir, an outer vaporizing tube concentrically secured on the. air tube, said concentric tubes having alined apertures in their walls, a spring-returned compression An outer compression cylinder 12 has feature of the invention is the lar e y reservoir permanently close cylinder telescoping over the upper end of the reservoir,-an air inlet valve in the head of the compression cylinder, an annular shoulder on the upper end of the reservoir,

. an inner annular flange on the lower end of the compression cylinder adapted to engage the reservoir shoulder, and a lug on the lower end of the reservoir adapted to pass through a slot in said flange,

2; n atomizer comprising a cylindrical reservoir permanently closed at itslower an aperture in the reservoir base with the- 'outlet tube, a cap having an annular projecting rim at its upper end and a depending annular flange adapted for screwthreaded engagement with the upper end of the reservoir, a packing ring secured in the cap by the annular rim, an air tube opening through the cap extending toward the lower end of the reservoir, an outervaporizing tube concentrically secured on the air tube, said concentric tubes having alined apertures in their'walls, a springreturned compression cylinder telesco ing over the end of the reservoir, an air inlet valve in the head of the compression cylinder, means limiting the outward movement of the compression cylinder and means adapted to lock the two cylinders in compressed position.

3. An atomizer comprisin ar -cylindrical et its lower end, an outlet tube extending from the lower end upward in the reservoir and having a laterally turned bell mouth upper end, a nozzle extending laterally from the lower endof the reservoir that is connected by an aperture inthe reservoir base with the outlet tube, a cap having an annular projecting rim at its upper end and a depending annular fiange adapted for screwthreaded engagement with the upper end of the reservoir, a packing ring secured on the cap bythe annular rim, an air tube opening through the cap extending toward erase the lower end ofthe reservoir, an outer vaporizing tube concentrically secured on the air tube by means afi'ording passages between the tubes for the entire length of the outer tube, said concentric tubes having alined apertures in their walls, a spring-returned compression cylinder telescoping over the upper end of the reservoir, and an inlet valve in the head of the compression cylinder, means limiting the outward movement of the compression cylinder and means adapted to lock the two cylinders in compressed position.

4. An atomizer comprising a cylindrical reservoir permanently closed at its lower end, an outlet tube extending from the lower end upward in the reservoir and having a laterally turned bell-mouth upperend, a nozzle extending laterally from the lower end of the reservoir that is connected by an aperture in the reservoir base with the outlet tube,'a cap having an annular projecting rim at its upper end and a depending annular fiange adapted for screwthreaded engagement-with the upper end of the reservoir, a packing ring secured on the cap by the annular rim, an air tube opening through the cap and extending toward the lower end of the reservoir, an outer vaporizin tube concentrically secured on the air tube y means afi'ording passages between the tubes for the entire length of the outer tube, said concentric tubes having alined apertures in their walls, a springreturned compression cylinder telescoping over the upper end of the reservoir, an air inlet valve in the lower head of the compression'cylinder, an annular shoulder on the upper end of the reservoir, an inner annular flange in the lower end of the compression cylinder adapted to engage the reservoir shoulder, and a lug on the lower endof the reservoir adapted to pass through a slot in said flange.
