ATOMIZER.

SPECIFICATION forming' part of Letters Patent N0. 790,318, dated May 23,v 1905.

i Application filed January 25, 1904. Serial No. 190,444.

l T0 a/ZZ whom t may concern,.-

Be it known that I, WALTER SAMS, a citizen of the United States, residing at Chicago, in the county of Cook and `State of Illinois, have invented a certain new and useful Improvement in Atomizers, of which the following is a full, clear, concise, and exact description, reference being ing drawings, cation. l

My invention relates to atomizers in which perfumery and liquids having medicinal and disinfectant properties may be used and wherein the vapplication of said liquids is effected by reducing the same to a spray.

My invention relates more particularly to that portion of the device employed in conveying the ejected fiuidfrom its containing forming a part of this specifil vessel, and has for its special object the provision of a duct adapted to be supported in working position with respect to a nozzle by frictional engagement with structuralA parts of the device.V Heretofore in devices of this nature the location of the ejecting end of the conveying-duct with respect to the nozzle has not only required fine adjustment, but in most constructions the permanent fixture of one part with respect to the other to obtain an effective working relation. In the fixture of one part-say the duct-the removal thereof forcleansinfr purposes and repairis prevented and when the parts become worn the adjustment of the duct and nozzle is necessarily altered, causing an imperfect and at times a totally ineffective operation.

One advantage of my invention is the provision of an inclosing tube for the conveyingduct with which the latter is frictionally and yieldingly engaged. Said tube preferably carries a nozzle, and the parts are desirably arranged to effect the adjustment of the duct in the operation of attaching the nozzle, and in the preferred construction said tube coperates in the atomizing operation by forming an air-chamber which, to ether. with the pump mechanism and nozz e, effects the reduction of the liquid in the containing vessel to a spray.

A further improvement relates to the pumping mechanism; and it 'consists of had to the accompanymeans whereby an air-inlet, in connection with a portion of the users hand, may act as a valve-seat and valve respectively, affording a simple and effective control of the air-intake for the pump.

I will explain my invention more particularlywith respect to the accompanying drawings, in whic Figure l is a vertical sectional view of an atomizer embodying the main features of my invention. Fig. 2 is a rear view, partially in section, taken on line 2 2 of Fig. 1. Fig. 3 is an enlarged detail view of the nozzle and the adjacent end of the conveying-duct. l,

Like parts are indicated by similar characters of reference throughout the accompanying drawings.

In the drawings a form of atomizer is shown in which the pump-barrel l is mounted upon the containing vessel 2, although my invention is serviceable in connection with atomizers of other constructions. The containing vessel 2 for the liquid is provided. with a removable metal cap 3, to which the cylinder of the pump l is secured. Said pump is also provided with a reciprocating piston 4, equipped with packing-disks, which is desirably operated in one direction by an expansively-acting spring 5, interposed between the end wall of the barrel l and the piston 1, and in the opposite direction by the inger or thumb of the operator applied to a button upon the rod 6 of the piston. A pipe 7 conveys the compressed airfrom the pumpbarrel 1 to the containing vessel 2, said pipe being desirably attached at one side of the barrel, as shown, to prevent the lubricant therein finding access to the containing vessel. A free or unvalved aperture 8 is provided, desirably in the end wall 8 of the pump-barrel, whereby the same may on the intake-stroke of the piston l communicate with the outer air. Said aperture is desirably closed on the compression or ej ecting stroke of the piston 4 by the finger of the o erator. Thus the operator by gras ing t e containing vessel with the body of t e hand and three fingers is able to use the thumb and Erst finger in operating the piston 4 and the intake in the end 8, respectively.

IOO

An inclosing pipe 9 is desirably provided, which in the preferred form is secured to thc removable cap 3 of the containing vessel and projects a short distance into the same and also acts as an air-chamber, which, in cooperation with the nozzle, effects the operation of the atomizer. Said pipe 9 is adapted to inclose the conveying-duct 10, extending throughout the length thereof and close to the bottom of the vessel. Said duct 10 is desirably of reduced diameter with respect to the pipe 9 and is provided between its ends with a supporting-leg 12, having an outward flexure which causes said leg to bear against the Wall of the pipe 9 and serves by frictional engagement therewith to maintain the duct 10 in its adjusted position in the said ipe. To this end the leg 12 is formed of resi ient material in order that its contact with the pipe 9 may eifectually sup ort said duct. An enlargement 13 is desirably mounted on the duct 10 and is provided with an aperture of less diameter than the interior of the duct. Said enlargement, together with the aperture therein, cooperates with the nozzle in the reduction of the liquid to a spray. I do not wish to be limited to the means shown for supporting said duct Within the pipe, as it is obvious that any form of frictional engagement not obstructing the passage in the pipe 9 would come within the spirit of the invention.

The nozzle 11 in the form shown is provided with a rearwardly flaring exterior adapted for insertion in the nostril when liquid to be sprayed is for medicinal purposes. This feature is not, however, an essential characteristic of the invention. An integral ange 15, having a stop or shoulder 16, is formed upon the nozzle to effect connection of the same with the adjacent end of the pipe 9, which engagement in the preferred forni is frictional. The internal diameter of said flange 15 is desirably uniform and referably extends from one end of the nozz e close to the opposite end, a wall intervening in which an axially-disposed aperture 17 is formed. Said aperture 17 and the aperture in the enlargement 13 are desirably in alinement when the parts are assembled.

When the duct 10 is inserted in the pipe 9, the outer end or enlargement 13 is permitted to project outwardly some distance from the pipe 9, the insertion of the duct not being completed in one operation. The nozzle 11 is then positioned upon the projecting end 13 of the duct 10 and is utilized to force said duct into its final position, which position is effected when the flange 15 is inserted into the` pipe 9 until the latter abuts against the shoulder 16. The construction affords an effective and easy means for inserting the duct and securing the nozzle and in the same operation effect the proper position of the duct with respect to the nozzle. After the parts have been forced into place a slightI relaxation, due to the release of pressure on the part of the operator and a rebounding action of the duct on the nozzle, causes a slight airspace between the inner face of the nozzle and the enlargement 13 to be formed. This air-space is supplemented by the inner enlargement of the aperture 17. An air-space also extends throughout the length of the tube 9. As air is forced from the pump 1 through the pipe 7 into the containing-chani ber it passes through the tube 9, forcing its way between the part 13 and the nozzle, and thereby forming a current of great velocity into which the liquid is drawn and separated into fine particles, causing a spray to vflow from the nozzle.

It is obvious that changes may readily be made in the embodiment of the invention herein shown and described without departing from the spirit thereof; but,

Having thus described my invention, I claim as new, and desire to secure by Letters Patent, the following:

1. In an atomizer, the combination with a vessel for containing the liquid, of an inclosing tube, a nozzle frictionally anchored thereon, a duct cooperating with said nozzle, and a spring secured to said duct and in frictional engagement with said tube, thereby supporting said duct within the tube, substantially as described.
