page_text: I WALTER ALFRED BARLOW of 6 St. Paul's Churchyard in the city of London
Patent Agent and Engineer do hereby declare the nature of this invention (a com-
munication from abroad by Hermann Emil Schrader Engineer of Hamburg in the
German Empire) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to improvements in bottle filling machines and has for its
object to draw off liquids from casks or other closed vessels into bottles under
exclosure of any other quantity of outer air than that contained in the bottles to
be filled. The quantity of air expelled from the bottles while filling passes through
the machine and over into the casks. The process of filling the bottles proceeds
in a better and more uniform way than in filling machines of hitherto known
construction. Especially for drawing beer from casks into bottles this new machine
is of great value as it causes less frothing or scumming of the liquid.
The machine is represented in the accompanying sheet of drawings whereof
Fig. 1 is a front elevation partly in section, Fig. 2, a side elevation in section after
line a, a, Fig. 8 a side elevation in section after line xx, and Fig. 4 after line y, Y,
Fig. 5 is a perspective view (on reduced scale) of the machine in combination with
a cask from which the liquid is drawn off into bottles.
A is a vessel that can be closed hermetically by a cover, and is supported by
brackets Q, and can by a flexible hose h and tube e be put in connection with
tap k of a cask R. The inner mouth of tube e, is clo-ed by a valve v, connected by
a float 8. At the beginning of the operation this float occupies a lower position
than shown in the drawing, and valve vis then open.
By opening tap k, liquid enters vessel A and a corresponding quantity of air
from A passes over into cask R until by the rising level of liquid float 8. closes
valve v.
This level m must be secured by adjustment as will be understood from
the further description.
To the front of the lower part of vessel A are screwed metal bosses C, C¹C',
furnished with several borings in which slide the metal cylinders d, dd, to the
tube like projection of each of these cylinders a nut f, f¹, ƒ³ is attached underneath

page_text: which an indiarubber ring o, o', o' is put onto each tube which ring is so shaped
that it hermetically closes the mouth of the bottle that has to be filled. .Between
each boss C, and its corresponding nut f is placed a spiral spring that keeps.
cylinder d. (furnished at its upper end with a rim i) tightly down on its boss C.
When pressed down (see Fig. 3) the cylinders d, d¹, d² etc are closed airtight and
no liquid can exit from vessel A.
When, for filling a bottle this latter is with its mouth put over one of the
rings o and the bottle then lifted, its corresponding cylinder & rises inside of
vessel A (Fig. 2) and liquid can pass through borings n (formed underneath ring i
in the sides of cylinder d) from vessel A through cylinder d into the bottle. The
air expelled from the bottle by the filling in liquid passes through tube g placed
inside of d and projecting at the top end above the level m into vessel A and from
here through and hose ¹ into cask R. The tubes g, g¹ gå etc from the corre
sponding cylinders & must at the upper ends terminate above level m of the liquid
in vessel A as otherwise the air would be prevented escaping from the bottle by
the liquid.
As soon as liquid is drawn off from vessel A float 8 descends and valve v opens
to allow new liquid to pass from cask R into vessel A and to keep a level of
nearly constant height which is required to prevent liquid from closing the opening
of tubes g, g¹ g².
Instead of lifting and keeping the bottles by hand to rings o this may be done
by stands Z turning on bolts and springs Z' as will be understood with reference
to the drawings.
Having now particularly described the nature and particulars of iny said
invention and in what manner the same is to be performed I declare that what
I claim is
g
In bottle filling machines the application of float and valve to keep a constant
level of liquid in vessel A in combination with air tubes 9 terminating above the
level of liquid in vessel A which tubes allow the air to pass over from the bottle
being filled into vessel A and thence by a hose or other suitable connection to
cask R, constructed and operating as and for the purpose herein set forth.
