T0 @ZZ 'tu/7,0711, it may 0072/0071721:

Be it known that I, ALBERT POWERS, a cirizen ofthe United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Stillsof which the following is a full, clear', and exact description, reference being had tothe accompanying drawings, forming a part hereof.

My invention has relation to improvements in domestic stills; and it consists in the novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claim. g

In the drawings, Figure l is a front elevation of the still, showing the parts in their assembled position. Fig. 2 is a middle vertical section on line 2 2 of Fig. 1. Fig. 3 is a top plan of the lower section or boiler, and Fig. 4 is a top plan of the -upper section.

The object of my invention is to construct.

a simple still adapted particularly for domestic, campiu g, and similar purposes, one which shall be cheap, durable, readily assembled or taken apart, and one possessing further and other advantages better apparent from a detailed description thereof, which is as follows:

Referring to the drawings, 1 represents the bottom section or boiler, the same being proT vided with a conical roof 2, having a central opening 3 for the escape of the stea1n, the lower edge of the roof being disposed in a plane a suitable distance below the upper edge of the boiler. ripheral wall of the boiler which is above the lower edge of the roof are formed a series of air vents or openings 4, adapted to register with a corresponding series of openings 4' of the upper section 5 of the still, the openings 4 being distributed in a plane adjacent to the upper edge of the boiler or section 1. Formed with the section 5 is a lower conical wall 6, having an opening 7, and an upper conical wall 8, having a conical perforated apex 8', the top of the apex being substantially on a level. with the upper edge of the section 5. Between the walls 6 and 8 is a condensingchamber 9, from the lowest point of which extends a delivery nozzle or tube 10, to which may be attached a suitable hose. (Not shown.) Froma point in the peripheral wall of the section 5 a suitable distance belowr the upper edge Along that portion of the pethereof leads an overfiow pipe or spout 1], the lower end of the same discharging into a pocket 12, communicating through an opening 13 directly with the boiler. The compartment 14 above thewall 8, from which the pipe' 1l leads, is the cold-water compartment, the said water serving to condense the vapor disengaged from' the yboiler and impinging against the lower surface of the wall 8. The registeringopenings 4 4 by reason of the aircurrents induced to How therethrough by the ascending currents of vapor from the boiler serve to admit an amount of cool air which in a measure has a tendency to partially condense the vapor in addition tothe complete condensation affected by the cool water in the compartment 14. The latter is filled through a funnel 15, mounted in a casing or tube 16, soldered to the inner wall of said compartment.

The operation of the still is as follows: The boiler is placed over a flame or stove, and the water therein as it becomes heated evaporates, the vapor rising and condensingin the chamber 9, the distilled water being discharged through the nozzle or pipe 10, from which it may be conducted to any suitable point of consumption. The bounding conical walls of the condensingchamber being substanstantially parallel, the vapor rising from the boiler first impinges against the lower wall, being thereby in a measure condensed before impinging againstA the upper wall of said chamber or that directly in contact with the' cold water in the compartment 14. In this Way the direct impingement of the vapor against the upper wall of the condensingchamber is prevented and the too-rapid heating of the-water in the compartment 14 is avoided. As the water in the cold-water compartment 14 becomes heated more cold water may be supplied thereto, the overflow passi ing through the spout 11 back to the boiler again. The perforation in the apex 8' is to relieve the stillfof any excess of pressure due to a too-rapid generation of steam. By having the bounding walls of the chamber 9 con ical or inclined the distilled or condensed water may readily flow to the discharge-nozzle 10.

During the operation of the still a small IOS quantity of condensed water will naturally collect around the lower edge of the roof 2 and eventually rise tothe openings 4. U11- der ordinary circumstances the air-currents passing through said openings will carry off mechanically any condensed water which might tend to flow out through said openings, and should the condensation beoolne too rapid the openings may be closed completely by giving the sections a slight turn about their common axis and destroying the register between the openings 4 and et.

It is of course apparent that minor changes may be resorted to without departing from the spirit of my invention.

Having described my invention, what I claim is- A still comprising a lower section or boiler, a conical roof for the same having a central opening, the lower edge of the roof being disposed in a plane below the upper edge of the boiler, an upper section adapted to be coupled to the upper edge of the boiler, the two sections having openings or air-vents adapted to register with one another, ata pointabove the base of the roof of the lower section, a condensing chamber in the upper section bounded bya lower and an upper conical wall substantially parallel thereto and separated by a suitable space therefrom, the upper wall having a perforated apex, and the lower wall having a central opening located above the corresponding opening of the conical roof of the lower section, a cold-Water compartment formed in the upper section above the upper wall of the condensing-chamber, a pocket located on the outside of the boiler and communicating with the interior thereof, an overflow pipe or spout leading from the cold-Water compartment and discharging into said pocket, and a discharge-nozzle leading from the condensing-chamber, the parts operating substantially as, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT POWERS.
