Application filed June 15,1891. Serial No, 396,237. (No model.)

To all whom it may concern:

Be it known that I, Edward T. Bates, a citizen of the United States, residing at Washington, in the District of Columbia, have in5 vented certain new and useful Improvements in Atomizers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains io to make and use the same.

My present invention relates to atomizers, and has for its object certain improvements in construction,which will be hereinafter described, and particularly pointed out in the 15 claims.

In the accompanying drawings,which form part of this specification, Figure 1 represents a side elevation; Fig. 2, a vertical section on an enlarged scale with the air-pressure regu20 lator expanded; Fig. 3, a detail perspective of the valve for controlling the supply of liquid, and Fig. 4 a side elevation of the flexible air-supply valve.

Reference being had to the drawings and 25 the letters thereon, A indicates a liquid-receptacle which may be of any approved form; B, a flexible bulb for supplying air under pressure; C, a T-shaped conductor for air and liquid, to the horizontal arm a of which the 30 bulb B or aiiy suitable air-supplying device is attached. The arm a is tubular, and within it is placed a tubular flexible and collapsible valve b, which is contracted at its front end d and controls the ingress of air to 35 the bulb B through ports c c in the arm a, and its egress through its contracted front end d, from which the air is discharged into the receiving and distributing chamber e. With the chamber e communicate two eon40 duits or passages f g, the former extending through the vertical branch h of the conductor C to supply air to the surface of the liquid in the receptacle A, and the pressure thereof is regulated by a flexible regulator D, 45 which is supplied through a port i, which communicates with the passage f. The regulator D is secured to the branch h by wrapping with cord or in any other suitable manner. From the branch h extends a tube k, through which 50 and the branch li extends a liquid-supply passage I, which at its upper end communicates with the passage g, which extends through the other horizontal arm m of the conductor C. In the lower end of the tube fc is inserted a valve n for controlling the supply of liquid 55 to be atomized, and in the body of the valve is a graduated groove or passage 0 for regulating the supply of liquids, according to the air-pressure applied or the density of the liquids, the light liquids under low pressure be- 60 ing supplied through the small portion of the passage and the heavy liquid under low pressure through the large portion of the passage, or the heavy liquid may be supplied through the small portion of the passage under a 65 higher degree of pressure. The branch fits a corkin the neck of the liquid-receptacle or may be provided with any suitable packing.

In the vertical branch hoi the conductor C 70 is a stop-cock s provided with ports t u,which register with the passages g and I when the atomizer is in use and cuts off the egress of liquid from the receptacle A and prevents waste while being carried in a case or on the 75 person.

To the outer end of the arm m is attached a flexible soft discharge-tube q, of soft rubber or other suitable soft material, which is provided with any suitable number of egress- 80 passages, as r, for atomizing and spraying liquid. This tube being of flexible soft material throughout its entire length is especially adapted for insertion into the nasal passages, the throat, or the ear, and may be bent and 85 twisted to follow the passage without danger of injuring delicate organs, which frequently attends the insertion of a conductor having a metallic or hard-rubber tip. The flexibility . of the conductor also admits of its being re- 90 volved while in a passage to direct spray or mist against any part of the passage.

The conductor C may be made of hard rubber or metal in sections connected by screwthreads, or it may be molded or cast and the 95 passages drilled.

Air being forced into the chamber e is distributed, a portion flowing down the passage /and a portion flowing through the passage g, where it meets the liquid rising through 100 the passages I and forces it through the arm m into the flexible discharge tube or con

460,458 ductor q, from which it is emitted in the form of atomized spray or mist.

By the relative positions of the inner end of the valve b, the chamber e, and the pas5 sages g and Z the air passing through g operates to raise the liquid Z on the principle of operation attending an ejector, aud by conducting the air which enters the passage f into the flexible pressure - regulator D and io then into the receptacle A the flow of liquid is regular and the atomized spray continuous and uninterrupted.
