SPECIFICATION forming part of Letters Patent No.v 380,041; dated March 27, 1888.

Application filed December 31, 1887, Serial No. 259,474. (No model.)

v To all whom, it may concern:

Be it known that I, GEORGE KNEUPER, of Y theA city -and county of New York, in the State of New York, have invented a new and useful Improvement in Atomizers, of which the following is a specification.

In my Letters Patent No. 363,247, dated May 17, 1887, I have shown and described an atomizer in which the liquid-receiver is formed wholly of elastic and expansible material, so that when the nozzle of the atomizer is closed air may be pumped into the Aliquid-receiver, e thereby expanding the receiver and forming therein a volume of compressed air, which will give a continuous spray when the finger is removed from the nozzle.

One object of my present invention is to so arrange and construct the air-tube leading from the liquid-receiver that it forms a sustainingpost to the receiver and renders an atomizer having such expansible liquid-receiver a more stable article when placed upon a table' or other support.

A further object o`f my invention is to reduce the costof atomizers having a compression-bulb for forcing air into the liquid-receiver, and to enable all those parts which are formed of flexible and soft india-rubber to be made without any valves, the necessary valves being in a structure surmounting the liquidreceptacle, and in which are comprised the air and liquid tubes of the atomizer, such structure being of hard rubber or other hard and rigid material.

The invention will be hereinafter more particularly described, and pointed out in the claims.

The accompanying drawing is an elevation, partly in section,of an atomizer embodying my 4o invention and comprising a liquid-receiver formed in one integral structure of soft indiarubber, and also comprising a compressionbulb t-o be 'operated by hand foei; compressing air within the liquidlreceiver. l"

Adcsignates the liquid-receiver, which consists of a bulb of soft and flexible india-rubber readily expansible under air, whichv may be compressed therein by a compression-bulb, B.

The liquid receiver A is surmounted by a 5o structure of ha'rd or rigid material-such, for

example, as hard vulcanized india-rubber or vulcauite-and which comprises a liquidftube, a, and an air-tube, C, and at the top of this structure is the spraying-nozzle c. l The air-tube C comprises a lower portion, C', whichextends downward through the liquid-receiver A and forms a continuationk of the portion C. rlhese two parts of the airtube are fitted together, as here shown, by'an ordinary slip-joint, c', which enables the noz- 6o zle and upper portion of this structure to be removed for the purpose of filling the liquidreceiver A. The portion C of the air-tube has a cylindric recess or socket, c2, which receives a neck, a', upon the upper-portion of 6;

the liquid-receiver A, and at the bottom the f liquid-receiver has a corresponding neck, a2, which enters a circular recess in a washerd, placed outside and below the liquid-receiver. The lower portion of the air-tube C extends through the neck a,2 and through the washer d, and has screwed upon it a base, D, on whicA the atomizer is supported.

The liquid-tube a extends downward within the air-tube -portion C nearly tothe bottom thereof, and such portion O of the air-tube has lateral openings c3, through which liquid may enter its interior, and near the top of the liquid-receiver also has openings c, through which air may escape from the air-tube into the re ceiver above the liquid therein.

In connection with the expansible liquid-receiver A at least one valve is necessaryto permit the entrance'of'air to the air-tube C and to prevent its escape therefrom to the atmosphere'. I have here shown such a valve at e, and if no compression-bulb- B be used this valve e is all that is necessary for operating the atomizer.v By grasping lthe expansible liquid-receiver A in the hand and compress` ing it, the air which it contains will be ejected from the nozzle c, and, drawing up liquid through the tube a, will eject spray from the nozzle. When the grasp of the hand on the bulb A is released, the valve e will open to allow the bulb in recovering itself to fill with air. As soon as pressure is again brought to bear upon the bulb, the air will be discharged therefrom, the valve c closing to prevent its escape to the atmosphere. I prefer, however, usually to employ a compression-bulb, B, and

ICO

a tube, B', by which the air maybe compressed i t to any desired pressure within the liquid-receiver A when the finger is applied over the nozzle c.

I have here shown the structure of hard or rigid material which surmounts the liquid-receiver A as having a lateral branch, C, with which the tube B of the bulb B is connected, and which contains both the valve e and a seeond valve, e. It will be understood that both these valve e e are comprised in the structure of hard or rigid material which surmounts the liquid-receiver, and the bulb B and its discharge-tube Bare destitute of valves, and therefore are very simple and correspondingly inexpensive in their construction. The bulb B, save for its opening to the tube B', is entirely imperforate and closed to the atmosphere. A very common construction for bulbs which are used to compress air is to provide the compression-bulb B at its one end-that is, the lower end in the drawing-with asuction-valve, and to provide it at its opposite end, where the tube B is joined onto it, with a dischargevalve; but when the bulb and its tube B B are valveless, as in my invention, their construction is greatly simpled, and the cost of the entire article is much reduced below what it would be if the two Valves e e were arranged at opposite ends of the compression-bulb B instead of in the structure of hard or rigid material surmounting the liquid-receiver A. Indeed, the compression-bulb B and its air-tube B may, if desired, be formed in a single piece of soft and flexible india-rubber without any openings Whatever, save that at the end of the tube B', where it is joined onto the lateral branch C. When the bulb B is compressed,

the air therein will be forced through the tube B, and, closing the valve e,wil1 open the valve e andv pass into the air-tube C C, and, if the finger be over the nozzle c, will pass downward 4bottom of the receiver a lateral inlet-opening and a liquid-tube extending downward in' the `air-tube and terminating near said lateral opening, substantially as herein described. l

2. The eombination,with theliquid-receiver of an atomizer formed wholly of an elastic and expansible bulb, of a structure of hard or rigid material surmounting the receiver and comprising the air and liquid tubes of the atomizer, and an inlet or suction valve for air also comprised in the said structure above the receiver, substantially as herein described.

3. The eombination,with the liquid-receiver of an atomizer and a surmounting structure of hard or rigid material comprising within it the air and liquid tubes of the atomizer, and having a branch, C2, wherein are the air-valve e, opening from said branch into said air-tube, and the air-valve e', opening into the branch, of aeompression-bulb, B, and atube, B,where by it is connected with said branch C', both said bulb and tube being destituteof any valves and the bulb being imperforate and closed to the atmosphere, save for the passage through the tube B', substantially as herein described.
