EVAPORATING OR VAPORIZING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 568,928, dated October 6, 1896.
Application filed UOtObBI 24, 1895. Serial No. 566,713. (No model.)
To all whom it ntay concern.-
Be it known that we, J AIRUS L. STRATTON and FRANK MURDocK, citizens of the United States of America, residing at Kansas City, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Evaporating or Vaporizing Apparatus, of which the following is a speciflcation.
[0 Our invention relates to improvements in an evaporating or vaporizing apparatus, and more particularly to certain improvements upon Letters Patentgranted to us and dated December 12, 1893, and reissued May 1,1894,
and numbered 510,825, and reissue 11,418, respectively, in which the fluid is held in a suitable receptacle,and a wick extending above the fluid draws up the fluid in such quantity as to be easily evaporated, and our pres- 2o ent invention relates more particularly to the regulation of the evaporation.
To such end it consists in an apparatus which is neat and compact and is capable of adjustment, so that a greater or less amount 2 5 of evaporation may take place, as may be required.
The invention is fully illustrated in the drawings presented herewith, in which Figure l is aside elevation of the apparatus,
0 showing the cover down in its closed position. Fig. 2 is a central vertical section through the line 2 2, Fig. 1. Fig. 3 is a side view of the apparatus, the regulating-cover being somewhat raised; and Fig. 4 is a horizontal sec- 5 tion in line 4 4, Fig. 2.
The apparatus in its preferred form has a fluid-receptacle A, outwardly flaringnear the bottom to form a base a. The bottom ct of the receptacle consists of a dish-shaped plate raised somewhat from the base, as seen in Fig. 2, and perforations a are provided in the base a, through which air may pass into the apparatus and up through a tube a secured to the bottom a, in any desired manner, and extending upward and into the evaporationchamber. A ring a is soldered or otherwise secured to the receptacle A, and is formed with spiral corrugations, as seen in Fig. 2. A diaphragm B is provided between the fluid, which is contained in the receptacle below, and the evaporating portion of the apparatus.
This diaphragm is secured to a ring I), (see Fig. 2,) which has a downwardly-extending portion 1), also spirally corrugated, as seen in Fig. 2. said spiral corrugation being adapted to be screwed into the corresponding corrugations in the ring 65*, thus forming a comparatively tight joint between the two compartments. The diaphragm is also provided with a flange b and between this flange and a hollow stopper 19 preferably of cork or of a similar nature, is secured the wick O, which extends down through the fluid and to the bottom of the receptacle. The wick extends upward to the top of the evaporation-chamber and, through its porous nature, absorbs the fluid and draws it up to the evaporatingcha-mber.
A perforated tube D is secured to the ring I) and extends upward to the top of the ap- 7o paratus, and is provided with a number of beads or corrugations d, extending around its periphery. A cap E is forced upon the tube D, the beads or corrugations fitting tightly upon the inner surface of the cap. The corrugations act as a spring against the inner surface of the cap and tend to hold the latter at any desired point, so that it may be raised or lowered along the perforatedtube to allow a greater or less amount of evaporation to take place.
The evaporation is kept up by a continu- 1 ous current of air passing through the apparatus, and the wick, extending through the entire body of the fluid, absorbs the latter, thereby causing the same quality of vapor from a partially-filled receptacle as well as would be secured from acompletely-filled one.
The compounds used in these evaporators 0 are intended to counteract disagreeable odors or to medicate the air in sick-rooms to prevent contagion or to cure diseases. The ap paratus is adapted for fluid or solid compounds, the receptacle A being intended to 5 hold the fluid, said fluid being drawn up by capillary attraction to the top of-the Wick, where it is evaporated and escapes through the perforations in the'tube D, and the evaporation is regulated by raising or lowering the cap, thus exposing more or less of the perforations, through which the vapor may escape. In the case of a dry compound it may be placed within the tube D. The entire upper portion can be wholly removed from the receptacle A and secured to any other suitable receptacle for holding the fluid.
It is obvious that various modifications and alterations can be made without changing the principle of this invention, as, for instance, instead of the perforated base legs might be attached to the receptacle to support the same, or the receptacle might be attached to a bracket supported by the wall, and other minor changes could be made without affecting the principle, but what we consider new and necessary to the embodiment of our inventionwill be more particularly pointed out in the following claims.
We claim as new and desire to secure by Letters Patent- 1. An evaporating or vaporizing apparatus comprising a diaphragm, B, having a central opening therein, an annular flange, b extending around said opening, an annular wick, 0, extending through said opening and suitably secured to said flange, a perforated tube, D, secured to the diaphragm and having the annular corrugations, d, the adjustable cap, E, fitted upon the outer peripheries of said corrugations, and the screw-threaded portion, b, adapted to be screwed upon a suitable fluid receptacle; substantially as described.
2. In an apparatus of the class described, the combination with a fluid-receptacle having a central longitudinal air-tube, of a perforated tube. D, having the annular corrugations, d, the diaphragm, B, having a central opening, the air-tube being arranged to extend through said opening, an annular wick, C, extending in said fluid-receptacle and tube, D, and the cap, E,supported bysaid annular corrugations, (Z, substantially as described.
3. In an apparatus of the class described, the combination with the annular fluid-receptacle, A, having the perforated supportingcries of the corrugations, (Z, substantially as described.
at. An apparatus of the class described comprising a suitable fluid-receptacle and airtube extending longitudinally through the same, a perforated tube, corrugations extending around said tube, a diaphragm separating said fluid-receptacle from said tube, an annular opening in said diaphragm, a suitablysupported Wick extending through the fluidreceptacle and into said perforated tube, and a cap adapted to be longitudinally adjustable upon said corrugated tube; substantially as and for the purpose set forth.
5. In an apparatus of the class described, the combination with a suitable fluid-receptacle, A, an air-tube extending longitudinally through the same, and a screw-threaded neck, (0, of the perforated tube, D, corrugations, d, diaphragm, B, having an annular opening, the flange, b, the wick, 0, extending through said fluid-chamber and through said perforated tube, said Wick extending around the air-tube, a and suitably secured to the annular flange, b the screw-threaded portion, 1), fitted to the neck, a and the cap, E, adapted to be longitudinally adjustable upon said corrugations; substantially as and for the purpose set forth.
