COMPLETE SPECIFICATION.
Means in connection with Household Receptacles 'for Enabling
Liquids to be Drawn from the same by means of Carbonic Acid.
I, ALBERT MULLER of 34 Friedenstrasse, Berlin, Germany, Engineer, do hereby
declare the nature of my invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
The present invention consists of improvements in jugs and other household
receptacles by means of which beer and other liquids may be drawn off from the
same through the agency of liquid carbonic acid, and the device consists of the
details of construction as hereinafter more particularly set forth.
According to the present invention a small receptacle filled with liquid carbonic
acid and provided with reducing valve is attached to a cover made in one with
or airtightly closed on to the receptacle in question, which is further provided
with a valve or tap for letting off the liquid contained in the said receptacle, said
liquid being driven out through the tap or valve by the pressure of the carbonic
acid gas in the receptacle.
And in order to render the present specification more easily intelligible reference
is had to the accompanying drawing in which similar letters of reference denote
similar parts throughout the several views:―
Fig. I is a vertical section through a cask-shaped receptacle for beer or the
like, showing the arrangement of the carbonic acid receptacle thereon,
Fig. 1 is a detail section through the outlet cock.
Fig. 2 is a plan of Figure 1,
Fig. 3 a side elevation of a different kind of receptacle and
Fig. 4 a similar elevation of another kind of receptacle. The receptacles of
Figures 1, 3 and 4 are also shown connected up to illustrate how one carbonic
acid chamber may be utilised for several receptacles simultaneously.
According to the present invention any kind of household receptacle whatever
such as jugs or pitchers of porcelaine, earthenware or glass or metal may be
employed, the same being provided with a hermetically sealed cover having two
nozzles thereon as. at s and h, one of said nozzles being for the reception of the
carbonic acid chamber and the other for the tap or cock through which the
contents of the receptacle are drawn off. The carbonic acid chamber D is filled
with liquid carbonic acid and provided with a suitable reducing valve
(not shown in the drawing) and a downwardly projecting stem having
at its lower end exterior Screw thread adapted to engage an interior
screw thread n of a fitting screwed to the central nozzles of the receptacle. The
said fitting B is provided with an interior downwardly extending tubular stem t
the lower end of which forms a seating for a conical or other valver having
upwardly projecting stem fast to a horizontal plate o¹ having two small orifices >2.
The downwardly extending end of the stem of the chamber D is provided with
astop valve m. Normally the valve r will be pressed upwardly and held closed
y a spring 7 assisted by the interior pressure of the beer in the receptacle. In

page_text: order to fill the receptacle the beer may be poured through the fitting B or the
latter may be taken off and the beer poured into the jug. In the latter case the
fitting should then be replaced and the carbonic acid receiver or chamber screwed
into the upper end of the fitting or sleeve B. When the cock m is opened
carbonic acid will pass into the receptacle and press on the upper surface of the
liquid therein forcing the same up the pipe g, which extends nearly to the bottom
of the receptacle and through the valve e, when the same is opened by hand, out
at the spout a into a glass or other receptacle. The cock or valve e is mounted
in the housing C screwed to the nozzle" of the beer jug cover, said housing
having therein a seat for the valve e against which the same is normally held by
means of a spring d bearing against a cap 61 within said housing C through
which the stem of the valve e projects said stem carrying at its upper end a
button which may be depressed by hand. Within the spring d is mounted on
the stem of the valve e an indiarubber sleeve c adapted to engage against a
seating formed in the housing C when the valve is depressed and prevent the
beer from escaping through the cover b. The valve r is further provided with a
spring which tends to normally hold the same against its seating.
The receptacle shown at Figures 1 and 2 may he provided with a handle u as
shown.
When the carbonic acid passes into the receptacle it passes through the holes o³
of the plate o and opens the valve r against the pressure of its spring.
When the button is depressed the beer will be forced up the pipe g and out
at the spout a. The housing C may be secured to the nozzle h by means of a
sleeve a tight joint being formed at f.
When one carbonic acid chamber is to be used for several receptacles, which
may contain different sorts of beer, the stem of the chamber 1) is advantageously
provided with a T-piece as at 7 to which a hose pipe or indiarubber tube S. is
attached which leads to the nozzle 12 of the next receptacle or to the T-piece / of
the next chamber, as at Figure 3.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what I
alaim is
1. A method of drawing beer and other liquids by means of carbonic acid, for
use in the household, which consists in applying to the beer receptacle a carbonic
acid receiver capable of operating several receptacles, either by being detached
from the one and attached to the other or by means of tubes connecting the
various receptacles, which may also contain different sorts of liquors (so that
liquor may be drawn off from all the receptacles simultaneously substantially as
described.
2. The employment of jugs of any form for household purposes and means in
connection with the same for drawing off the contents by means of liquid carbonic
acid, which consist in hermetically closing the said jug, and forming thereon two
nozzles, one of which enables the liquor to be filled to the jug and is adapted
subsequently to receive the carbonic acid receiver, being provided with an auto-
matically opening valve and the other being provided with an automatically
closing outlet valve substantially as described.
