Improvements in Means and Appliances for Drawing-off Liquids
from Casks and, other Vessels.
I ALBRECHT MARTIKKE, of 28111 Chausseestrasse, Berlin, N. in the Empire of
Germany, Manufacturer, do hereby declare the nature of said invention and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of my invention is to manufacture an improved apparatus for drawing
from casks, and other vessels, liquids, such as beer and wine, and volatile and
inflammable liquids, and liquids containing carbonic acid gas, and other liquids
requiring special means for excluding the atmosphere therefrom.
And in order than my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation showing the method of applying my invention to an ordinary
barrel. Fig. 2 is a section on the line 1-2 of Fig. 3, and Fig. 3 is a plan of the
same. Figs. 4, 5, 6 and 7, are detail plans and sections.
a is a tap, forming part of the apparatus, which is driven or screwed into the
barrel c.
b is a cylinder fitted with a piston d. The piston rod d' is formed with a
screw thread. e is an elongated tubular nut, capable of rotating in the guide ring f
is a rod fitted to the piston d, passing through a hole in the cylinder cover, which
prevents the piston turning on its centre. h is a handle fitted to the tube e for
turning the same by hand. i is a fork fitted to the handle h for engaging the pipe m
when raised to the position shown in Fig. 1, and k is a fork for engaging the lever
when the pipe is down in the position shown in Fig. 2. m is a stout pipe, of small
internal diameter, leading to the vertical pipe p and to the vent peg s¹. The pipe m
has a stop cock n, near the vent, and another stop cock o at the top of the pipe p..
This pipe p communicates with the underside of the piston d. u is a valve opening
inwards to the cylinder-b, below-the piston, and-visa valve opening outwards to the
delivery pipe w. x. a are screw plugs for convenience in cleaning the passages.
y is a cock fitted to the pipe a. s, Figure 4, is a plan of the bung inserted in the top
of the barrel. Fig. 5 is a section on the line 3-4 of Fig. 4. s Fig. 6 is a plan of
the metallic vent, inserted in the bung s, and Fig. 7 is a section of the same, on the
line 5-6.
The operation of the apparatus is as follows:-Supposing the barrel c to be filled
with beer, and the apparatus fixed as shewn in the drawings, the cocks n and y are
opened. The piston d is then raised by turning the handle h. As the piston rises,
beer enters the cylinder b, air being entirely excluded. At the same time a vacuum
is formed above the surface of the liquid in the cask or barrel. When the piston d
When
has risen to its highest point the cock o is turned off by the fork i, thus shutting off
the communication between the vacuum in the barrel and the underside of the piston,
such communication remaining cut off until the piston has again descended, and
reached its lowest point in the cylinder. As the piston d descends the valve u closes
and the valve v opens, whereby the liquid is drawn off by the delivery pipe w.
the piston is again raised the cock o is opened by the fork turning the lever r,
whereby communication is opened between the cylinder b, below the piston, and the
vacuum in the barrel c increases each time beer is admitted under the piston d, by the
raising of the piston.
My invention is applicable to all kinds of liquids, in which it is desirable to obtain
a more or less perfect vacuum above the same.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-.
1. In apparatus for drawing off from vessels volatile, inflammable and other
liquids, containing carbonic acid or other gases, the method of effecting such drawing
off with the exclusion of the atmosphere, and thus producing a more or less perfect
vacuum, substantially as hereinbefore described and illustrated by the drawings.
2. The general construction arrangement and combination of the several and
respective parts, together forming my invention of improvements in means and
appliances for drawing off liquids from casks, and other vessels, substantially as
herein before described and illustrated by the drawings.
