' WATER-STILL.

Specificatin of Letters Patent. Patented Aug. 3 1, 1909.

Application filed June 1, 1909. Serial No. 499,488.

To all whom it may concern:

' Be it known that I, HENIEY J. BEHRENs, a

citizen of the United States, residing at \Yinona, in the county of \Vinona and State of Minnesota, have inventedcertain new and pseful Improvements in WVater- StiIls, of ,which the following is a specification. v My'lnvention relates to certain new and useful improvements in water stills, and the object of my invention is to provide a novel, simple, highly efficient and practicable water still particularly adapted for household purposes.

With these and other objects in view my invention consists in certain constructions, combinaions and arrangements of parts the preferred form of which will be first described in connection with the accompanying drawings and then the invention particu- 'larly nted out in the appended. claims.

Re erring to the drawings wherein the same part is designated by the same reference numeral wherever it occurs Figure 1 is a perspective view of a still constructed in accordance with m invention and Fig. 2

' is a central longitudinal section of Fig.- 1.

The still, preferably, is constructed in circular form and composed .of two main parts 3 and 4, the latter seated on the former and readily detachable therefrom. The lower part 3 is provided in its upper' portion with a part 5 in the form of a truncated cone which is supported in the interior of the part 3 by the flange 6 which extends from the lower edge of the-cone to the side of the part 3. Preferably, and as shown, the part 3 is provided with a spout 7 secured on its side and communicating with the interior 1 'of the part 3 by means of the opening 8 whereby water to be distilled can be poured into the part 3, without removing the upper 'part 4. The cone 5 andthe flange 6 divide the lower part 3 into two sections, that portion above the flange and outside of the cone being adapted to receive the distilled water as will be hereinafter described. '9 is a faucet by means of which the water "can be drawn from the chamber above the flange 6 as desired. Located at the lower end of the' upper part 4 is a truncated cone 10 which extends from substantially the -lower edge of the upper part 4- upwardly into the same. 11 is a collar secured adjacent to the upper edge of the,cone and extending upwardly therefrom. Preferably,

and as shown, the lower edge of the collar boil.

is secured a short distancedown from the upper edge of the cone, whereby a ,shelf12 1s formed WhlCll 1s perforated as shown at 13 to permit water condensed on the inner surface of the collar to flowdown throng-h secured a collar 15 which surrounds thecone and extends upwardly therefrom,

16 is a cone secured atiit's lower edge to the upper edge of the collar 15 and extend ing over the collar 11. Extending fromthe apex of this cone is a vent pipe 17.

18 is a faucet extending out through" the side of the upper part 4 .in order to draw off the water containedthereinu.'. 19 is asection of pipe extending through the cone 10 and up into the lower edge the cone 14, whereby water contained ,i1 .the

the cone 16 Will'be drawn off into the section of the lower part 4 above the flange 6, as will be clearly SGGHTIOIIIFlg. 2.

In the operation of my still the lower por tion '3 is filled with water to be distilled. Heat is applied and the Water brought to a 1e upper portion 4 is then filled with cooled water, said cool water surrounding the exterior of the cone 10, extending up between the collar 11 and the cone l4 and covering the cone l6.- As the steam from the water contained in the lower part 3 rises it comes in contact with the cooled surfaces of the underside of the cone 10, condensesthereon and runs down the side of the cone and drips into the portion of the lower part above the flange 6. The steam also condenses on the collar 11,runs down theinterior thereof and passes through the opening 13 whence it runs down the underside of the cone with thewater condensed upon the under surface thereof. A portion of the steam also passes up into the cone 16 Where it condenses and accumulates between the. collar 15 and the. cone '14, this water being drawn 01f by the pipe 19, through which it runs into the receiving chamber inthe lower portion. When the water in the wpper portion becomes warm it can be drawn off through the spigot 18 and replaced with cold water. The disspace between the cone 14,thecollar 15-and tilled water can be drawn oil through the I s i ot 9 and the lower art filled b Y ourin a: l 3 P s 1 rendering interruption of the operation unnecessary The pipe 17 is to prevent too great a pressure being produced in the still. in the ordinary action of the still no steam escapes through this pipe, as the water which condenses therein operates as a sort of valve to prevent the escape of the steam.

l realize that considerable variation is possiblcdn the details of construction and arrangement of parts Without departing from the spirit of my inventioinand I therefore do not intend to limit myself to the specific form shown. and described.

' lilaving thus described my invention what I claim as new and desire to secure by Let-- ters Patent is l. A water still comprising two parts one located above the other, a. truncated cone supported within the lower part and dividing the same into a lower chamber for the water to be distilled, and an upper annular chamber adapted to contain' the distilled water, a truncated cone-shaped part extending from the lower edge of the upper part, a collar extending upwardly from the inner portion of said truncated-cone, a second truncated-cone extendingoutwardly from the upper edge of said collar, a second collar supported on the outer edge of said lastmentioned truncated cone, and a cone extending from the-upper edge of said collar ineas est) closing the structure within the second partof the still, said two truncated cones, said collars. and the cone which are in the upper part of the still forming the inner walls of said upper part, whereby said Walls form condensing surfaces.

2. A water still comprising two parts one located above the other, a truncated cone supported within the lower part and dividing the same into a lower chamber for the water to be distllled, and an-upper annular chamber adapted to contain the distilled inclosing the structure Within the second part of the still, and an open pipe extending from the apex of said cone, said two truncated cones, said collars, andthe cone which are in the upper part of the still forming the inner walls of" said upper part, whereby said wallsfform condensing surfaces.

in testimony whereof I afiix my signature in presence of two Witnesses.
