Patented June 17, 1947 UNITED STATES PATENT OFFICE EVAPORATOR Melville Keim, Chicago, Ill.
Application `uly 14, 1944, Serial No. 544,978
1 Claim. 1
The invention relates to improvements in evaporators especially adapted for use in desseminating room deodorizing or other vapors, and has for its primary object the provision of an improved arrangement of this character which is of simple construction and highly eicient in use.
Other objects will appear hereinafter.
The invention consists of the combinations and arrangements of parts hereinafter claimed and understood.
The invention will be best understood by reference to the accompanying drawings forming a part of this specification and in which- Fig. 1 is a perspective View of an evaporator embodying the invention and shown in condition of use;
Fig. 2, an enlar-ged vertical section through the upper portion of said evaporator;
Fig. 3, an enlarged vertical section through the upper portion of the evaporator showing the same in condition of non-use; and
Fig. 4, taken substantially on line 4 4 of Fig. 3.
The embodiment of the invention illustrated in the drawings comprises a cylindrical wick I which is doubled upon itself to form a loop II, the doubled end of said wick being secured to the body thereof by means of a binding I2. A lifting element I3 is secured to the loop II by passing the loop of the Wick through an opening I4 provided in said lifting element I3, The wick thus provided is of a size and shape adapted to be arranged in a container such as a bottle I5 having an inwardly tapering mouth I6, through which said loop II is adapted and arranged to protrude as indicated. As shown, the lifting element I3 is in the form of a at plate which may be conveniently made of molded or cast plastic material and is of a size and shape to be stopped by the inward taper of the mouth I6 at a point of suitable insertion of the wick into the bottle I5. By this arrangement the wick loop may be readily withdrawn from the bottle to Various positions of adjustment and opened and expanded as indicated, in Fig. 1, to increase its exposed surface and correspondingly increase the rate of evaporation. When it is desired to discontinue the evaporator the loop II is compressed and forced downwardly through the mouth of the bottle into the body thereof, until the lifting element I3 engages the inward taper of the mouth I6 to limit the insertion of the wick at a point Where the lifting element I3 may be readily grasped by the iingers and the Wick withdrawn from the bottle.
When not in use, an ordinary screw cap may be applied to the bottle as indicated in Fig. 3, thus preventing any further evaporation. In this way means are provided for greatly facilitating the manipulations of the wick and preventing insertion thereof into the bottle too far to permit of ready withdrawal when desired.
The specic form and arrangement of parts is a simple and effective one for the purpose.
While I have described the preferred form of construction for carrying the invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I therefore do not wish to be limited to the precise details disclosed, but desire to avail myself of such modifications and variations as fall Within the scope of the appended claim.
I claim:
The combination with a container having a downwardly tapering mouth; a plate member ydownwardly tapering in form and of a size to enter said tapering mouth completely and then interlock with said mouth to prevent further insertion; said plate member having an opening in its lower part; a wick looped through said opening; and said wick having a double thickness extending into said container.
MELVILLE KEIM.
