ATOMIZER.

Specification of Letters Patent.

Patented Sept?, 1907.

Application filed April 20,1907. Serial No. 369,305

To all whom it may concern:

Be it known that I, FRANK C. DORMENT, a citizenof the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Atom- This invention relates to atomizing means, wherein the jet is projected through a suflicient air space to insure its being inely and thoroughly vaporized, and at the same time, in ysuch direction as to preclude any liquid escaping from the douche tube or mouth piece,

or being drawn into the compression chamber to the injury of the working parts, while the compact arrangement and disposition of the parts is such that the in` strument is readily carried in the .vest pocket. p

The invention consists in the matters hereinafter set forth, and more particularly pointed out inthe appended claims. l i

Referring tothe drawings, Figure 1 is a view, greatly enlarged, in longitudinal section through an atomizer embodying features of the invention; Fig. 2 isa similar view ofthe atomizer with an outer air valve.

The atomizer comprises a pair of cylinders preferably of the saine size, securedv at their upper ends in par allel, spaced relation to a plate 1, which conforms closely to their contour. While! these may be of any suitable material, such as rubber ,or the like, in the preferred form of construction these cylinders areeach drawn out of a piece of suitable sheet metal, withone end integral with the cylinder wall. One of these cylinders 2 is provided with a central aperture struck through its end wall 3, the upturned resultant flange 4 being passed through la similar aperture in the plate 1 i and pressed flat against the plate to secure the parts 9 is inserted between thel cap and cylinder, and may' be conveniently secured thereon by carrying out the head of the cap beyond its flange and turning it with a square bend 10 which forms a seat for the ring. y

The piston stem 11 is longitudinally reciprocable in the apertured end of the cylinder. Its upper end is screw-threaded and a circular disk or thumb plate 12 is removably secured thereon. A piston 13 is secured to its inner end. As a suitable form of construction, this consists of a circular metal plate having a fair sliding lit in the cylinder, provided with an outer annular flange 14 or bearing surface against the cylinder wall, and an inner annular flange 15 by which itis held in alinement on the stem. A packing disk 16 of flexible the internal diameter of the cylinder, so that it is cupped, its margin packing the cylinder tightly on its downward stroke and drawing away 'from the piston fwall and head on the up stroke so that air may pass around it.

While the other parts may be of any preferred condisk be applied as designated. c y A spiral spring v19 is in compression between the cylinder cap and piston face, to return' the piston. Pref `erably it is a conical helix, to avoid striking the coils together and to clear the walls.`

The closed end or bottom 20 or the other cylindcr21, or atomizing chamber, is imperforate. A finish and stiffening bead 22 is formed near its upper open end,

struction, it is an essential feature that -the 'packing/,80

and screw-threads 23 above the bead engage the screwthreaded flange 24 of a cap 25'. lThe head of the latter is formed with a square fold 26, adapted to retain a packing ring or gasket 27, and is centrally apertured,

the margin 28 ol' the aperture being passed through an sign is movably secured in the bushing, and may have interchangeable nasal, aural or other end pieces detachably secured thereon.

An air tube 33, preferably of drawnsheet metal, connects the cylinders. In a preferred valveless form of construction, its lower end 34 is inturned directly into the piston cylinder'2 below the piston near the bead of the parts.

S, above which it extends parallel to. the cylinders through a suitable aperture in the plate 1.l A U-bend 35 is formed in the pipe above the plate, and the downward arm 36 extends vertically down through the plate fand cylinder cap 25, Whose aperture is provided with a Wide'annular flange 37, that forms a lon'g bearing. for

and close joint with the tube. A vaporizing tube 38 bent at right angles near its upper end with ,a round turn, is secured in the atomizing cylinder, the end of its short horizontal arm beng-brazed or otherwise rigidly'attached to the bushing 29 and against the end of the tube'33, and its vertical arm extending nearly to the bottom of the cylinder. A small orifice 39 in the upper `side of the tube 38 and a slightly larger aperture 40 in the underside, both in axial alinernent with the arm 36 of the air tube', forms a spray nozzle or vaporizer which projects the spray thewhole length of the cylinder toward the bottom. Air is admitted above the piston by orifices 4l in the cylinder head. l

In another form of the atomizer, the lower end of the air tube is bent into a U, and secured longitudinally against the side of the piston cylinder near its lower end. An aperture 42 (Fig. 2) extends through the contiguous walls of the tube and cylinder. The upturned end of the tube is drawn in or contracted and forms a seat for a ball 43 which is movable ina valve cap 44 closing over the tube, with an inverted seat 45 on its upper end, which is sealed by the ball against outward passage of air. i

One of the features of the invention is the accessibility By removing the thumb plate on the piston, andthe piston cylinder cap, the piston is readily'pushed'out.' In replacing the parts, the piston is pushed back, and the packing disk drawn in, so that its margin easily follows, there being no difficulty in getting the pliable edges to enter the cylinder, asin the usual l'orm of construction where the pushing in of the piston from the top of the cylinder rumples the edges of the packing disk and ultimately renders it useless.

In operation, the down stroke of the piston causes au air.blast through the orifices in the vaporizing tube,`

vof the cylinder. This long passage through the air space insures very fine division and dissemination ol' the parts, and at Ithe same time any drops of condensation are-tlnr'iwn down and trapped so that they ca nnot I escape through the mouth piece and come in Acontact with the users tissues. The upstroke ofthe piston draws air into the compression cylinder, but cannot cause sufiicient back pressure or sucti'on to raise the liquid or medicament the length el' the vaporizing tube, so that no moisture can get in to the piston cylinder and' corrode it or otherwise impede its action.A At the saine time the cylindrical shape, of the atom# izing chamber gives are-quisite long air space for complete atomizing without increasing the outer bulk of the instrument, which` lmay be very small to fit it for the vest pocket, the inturning of the mouth piece over the piston stem still further reducing its'sizei Another feature is the fact that a small amount of The parts are readily made at small cost and are of a mlinimum number of joints and. consequently little liability for leakage. l

Obviously the design and details of .construction the invention, and I do not limit myself to any particular form or arrangement ol' parts.

lWhat I claim as my invention isz- An atomzer comprisingr a. horizontal outer plate, an atomizer and cylinder whose lower end is permanently closed, and whose open upper end detachahly engages a cap secured to the under side of the plate, a mouth piece removably secured in the aperture through the cap and plate, a vaporizer secured in the cap whose supply tube extends longitudinally to theI bottom of the cylinder and has jet orifices near its' upper end adapted `to throw a spray jet longitudinally down the cylinder and whose air tube extends longitudinally through the cup and plate, a piston cylinder parallel to the atomizer and cylinder whose upper integral h'ead is secured to the under face of the said plate and whose lower compression end is provided with a detachahly secured head, a piston whose stem extends through a guide aperture in the upper head und plate, and whose head is provided on its outer face with a cup shnted, flexible packing disk, the lower end of said air tube heini',- connected to the lower compression end of the piston cylinder, air inlets in the piston cylinder above the pistou head, and n spring in compression heltween the lower cylinder head and piston. r
