IMPROVEMENTS IN VESSELS FOR CONTAINING LIQUIDS AND IN TAPS AND VENTS FOR THE SAME
Year: 1884

page_text: I JAMES REID BLAIR of 76. Moss Lane West, Manchester in the County of
Lancaster, Wine and Spirit Merchant, do hereby declare the nature of said
Invention for IMPROVEMENTS IN VESSELS FOR CONTAINING LIQUIDS AND IN TAPS
AND VENTS FOR THE SAME to be as follows:-
The object of my Invention is to admit air to assist the flow of beer or other
liquid in earthenware jars or other vessels, while the liquid is being drawn.
When I apply my Improvements to a jar I form an air passage that extends
from near the tap hole to the top of the vessel inside and I make a tap in which:
are two passages, one for the liquid to pass through, and one communicating with
the air passage. The spindle or plug of the tap is so formed that when the tap is
opened to allow the liquid to escape air is admitted through the passage to the
upper part of the jar above the liquid and when the tap is closed the admission of
air is stopped.
When I apply my Invention to a cask or other vessel not made of earthenware
I employ a tube that communicates with the air passage in the tap and with the
interior of the cask or other vessel above the level of the liquid. This tube may
also be used for earthenware vessels.

I JAMES REID BLAIR, of 76 Moss Lane West, Manchester, in the County of
Lancaster, Wine and Spirit Merchant, do hereby declare the nature of said
Invention for IMPROVEMENTS IN VESSELS FOR CONTAINING LIQUIDS AND IN TAPS
AND VENTS FOR THE SAME, 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 admit air to assist the flow of beer or other
liquid in earthenware jars or other vessels, while the liquid is being drawn.
When I apply my improvements to a jar I form an air passage that extends
from near the tap hole to the top of the vessel inside and I make a tap in which
are two passages, one for the liquid to pass through and one communicating with
the air passage. The spindle or plug of the tap is so formed that when the tap is
opened to allow the liquid to escape, air is admitted through the passage to the
upper part of the jar above the liquid and when the tap is closed, the admission
of air is stopped.

When I apply my Invention to a cask or other vessel not made of earthenware
I employ a tube that communicates with the air passage in the tap and with the
interior of the cask or other vessel above the level of the liquid. This tube may
also be used for earthenware vessels.
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings reference
being had to the figures and letters marked thereon,
Figure 1 is a sectional elevation illustrating my improvements as applied to a
jar for containing liquid, the plug of the tap being. turned so as to open the
passages for the liquid and for air. Fig. 2 is a similar view showing the tap
and part of the jar, the plug being turned so as to close both the liquid and air
passages. Figs. 3 and 4 are sectional elevations illustrating my improvements as
applied to a cask or other vessel.
Similar letters refer to similar parts throughout the several views.
In Figs. 1 and 2. a is the jar formed with 'an air passage b extending from near
the tap hole to the top of the jar: c is the tap formed with two passages b¹ and d
respectively, of which the former b¹ communicates with the air passage b and the
latter, d, communicates directly with the interior of the jar and is for the liquid
to pass "through; e'is the plug of the tap provided, with an opening 62 corre-
sponding with the air passage 61 and an opening d¹ corresponding with the liquid
passage d.
When the plug e is in the position shown in Fig. 1 the tap is open, the opening d
being opposite the passage d and the opening b² opposite the passage b¹, liquid is
free to escape from the jar through the passage d and opening d¹ and at the same
time air is admitted through the opening b² and passages b¹ and b to the upper
part of the jar above the liquid, and when the tap is closed by turning the plug e
into the position shown in Fig. 2 the flow of liquid and the admission of air are
stopped simultaneously,

page_text: In Figs 3 and 4 which illustrate my Improvements applied to a cask f the air
passage b' in the tap c is connected to and communicates by a tube with the upper
part of the interior of the cask above the level of the liquid.
Fig. 3 shows an india rubber or other tube bs placed outside the cask fand
Fig. 4 shows a tube bi passing through the head of the cask f near the tap hole
and extending upward inside to the top of the cask.
Either of the arrangements shown in Figs. 3 and 4 may be applied to earthen-
ware vessels.
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 claim is
1. The combination of a jar formed with an air passage and tap hole, of a tap
provided with two passages, one for air and the other for liquid, substantially as
and for the purposes herein described and as illustrated by Figs. 1 and 2.
2. In a jar a, or other vessel, for containing liquid, the air passage b substan-
tially as and for the purposes herein described and as shown on Figs. 1 and 2.
3. The tap c formed with separate liquid and air passages controlled by a single
plug, substantially in the manner herein shown and described for the purposes
specified.
4. The combination of a cask, or other vessel, provided with an air tube and
tap hole of a tap provided with two passages, one for air and the other for liquid,
substantially as and for the purposes herein described and as illustrated by Figs. 3
and 4.
