WILLIAM TROW, 131, Herbert Road, Small Heath, Birmingham, Engineers
Foreman, do hereby declare the nature of this invention to be as follows:-
Improvements in glass or other bottles.
The bottle is constructed with one or more vents or air passages at points
determinable in the neck of the bottle on the inside consisting of air channels or
tubeular passages running from points in the neck to the highest point in the
shoulder of the bottle when it is being held at the required angle for pouring off
the contents.
By these means a free and uninterupted flow is given to the contents, thereby
preventing the shaking of the liquid which is caused by the air bubbles running
from the neck into the body of the bottle. By its application a great saving
of time would be accomplished as in the case of bottled ales and sinilar liquids
where great care and consequently much time is required to run off the contents
clear and undisturbed.
1, WILLIAM TRow, of No. 45, Waverley Road, (late of No. 131, Herbert Road),
Small Heath, Birmingham, Engineers Foreman, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
-
My invention relates to glass and other bottles for containing ale, beer and other
liquids where great care has ordinarily to be exercised, and much time consequently
lost in the pouring off of the contents of the bottles so as to ensure the obtaining
of a clear liquid that is a liquid free from sediment; and my invention consists in
providing the necks of the said bottles with vents, tubes, passages or channels
which on the inclination of the bottle for the pouring off of the contents will
permit air to enter the mouth of the bottle and pass to the highest point in the
shoulder of the same without the bubbling which ordinarily occurs and the con-
sequent shaking of the liquid and stirring up of the sediment; a free steady and
uninterrupted flow of liquid being thereby obtained.
Figure 1 of the accompanying drawing represents in elevation a bottle provided
with an air passage or channel a at one side according to my invention and
Figure 2 is a cross section through the neck of the said bottle the said section being
taken on the dotted line x, x Figure 1.

page_text: Figure 3 is a cross section through the neck of a bottle provided with two air
passages or channels a, a at opposite sides of the neck of the bottle; and Figure 4
is a cross section through the neck of a bottle provided with three air passages or
channels a, a, a at equidistant points in the said neck of the bottle.
It will be seen by an examination of Figure 1 that the air passage or channel a
starts at a point a little below the mouth of the bottle and terminates at the
shoulder of the same the air passage or channel a being so inclined that it joins the
shoulder of the bottle at the part where the said shoulder passes into the body or
widest part of the said bottle.
In pouring off the contents of a bottle constructed according to my invention the
bottle is inclined with the air passage or channel a, or one of them where more than
one are used, on its upper side. By so doing air entering the mouth of the bottle
escapes by the said channel a over the surface of the liquid in the neck of the
bottle and enters the body of the bottle accelerating the freedom of flow and main-
taining clearness of the liquid.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that I claim as
my invention:-
-
The improvements in bottles herein before described and illustrated in the accom-
panying drawing, the said improvements consisting in providing the necks of the
said bottles, each with one, two or more vents, air tubes, channels or passages com-
mencing at a point in the neck of the bottle a little below the mouth of the same
and terminating at the shoulder of the bottle and at the part where the said shoulder
passes into the widest or body part of the bottle substantially as and for the purpose
hereinbefore described and illustrated.
