this invention to be as follows
This invention relates to the construction of vent and gimlet taps in such a manner
that when they are applied to casks or other vessels, air can enter the vessel and liquid
can issue from it without interference of the one current with the other. For this
purpose, a vent tap, according to this invention, is made with a bend as usual and has
two passages through it, a main or larger passage for liquid, and in front and above
this and parallel to it a small passage for air. Both passages are governed by the plug
of the tap, through which there are two parallel holes. The entering mouth of the
air passage is situated at some distance above the mouth by which the liquid issues
from the tap, and the mouth by which the air issues into the vessel extends some
distance beyond the mouth by which the liquid enters its passage through the tap.
Thus when the tap is turned to open both passages, air enters freely while liquid issues.
freely without interference of their currents, and by turning the tap partly round both
passages are closed.
In a similar manner a gimlet tap has its air and liquid passages arranged so that the
currents do not interfere with one another. The handle of the gimlet is bored some-
what more than half way along its length, and this bore communicates with a bore
which is carried some distance along the stem to a lateral opening from the stem
opposite to the mouth of the bore in the handle; this forms the passage for liquid.
Within this passage in the stem a-small tube which opens at front in the middle of the
handle is led to the lateral opening of the stem at the back of which it terminates
with an upward bend; this tube serves for admission of air. Thus on the gimlet
being worked to bore into the cask, when the lateral hole of the stem presents itself
upwards in the cask, the bore in the handle being then directed downwards, liquid
issues from the lower end of the handle, while air enters by the mouth of the small
tube at the middle of the handle and issues from this tube at its bend behind the
ingress of liquid to the stem.

page_text: 1, ANTOINE VAUDIOT of Tarare, Rhone France 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 :-
This invention relates to the construction of vent and gimlet taps in such a manner
that when they are applied to casks or other vessels, air can enter the vessel and liquid
can issue from it without interference of the one current with the other. For this
purpose a vent tap according to this invention is made with a bend as usual and has
two passages through it, a main or larger passage for liquid, and in front and above
this and parallel to it a small passage for air. Both passages are governed by the plug
of the tap, through which there are two parallel holes. The entering mouth of the
air passage is situated at some distance above the mouth by which the liquid issues
from the tap, and the month by which the air issues into the vessel extends some
distance beyond the mouth by which the liquid enters its passage through the tap.
Thus when the tap is turned to open both passages air enters freely while liquid issues
freely without interference of. their currents, and by turning the tap partly round,
both passages are closed.
In a similar manner a gimlet tap has its air and liquid passages arranged so that the
currents do not interfere with one another. The handle of the gimlet is bored some-
what more than half-way along its length, and this bore communicates with a bore
which is carried some distance along the stem to a lateral opening from the stem opposite
to the mouth of the bore in the handle; this forms the passage for liquid. Within
this passage in the stem,a small tube. which opens at front in the middle of the handle
is led to the lateral opening of the.stem at the back of which it terminates with an
upward bend; this.tube,serves.for,, admission of air., Thus on, the gimlet being
worked to bore into the cask, when the lateral hole of the stem presents itself upwards
in the cask,, the bore in the handle being then directed downwards, liquid issues from
the lower. end of the handle while air enters by the mouth of the small tube at the
middle of the handle and issues from this tube at its bend behind the ingress of liquid
to, the stem,

Figs. 1 to 4 shew, the construction of a vent tap according to my above described
invention. Fig. 1 shews a longitudinal section. Fig. 2 shews a sectional elevation.
Fig. 3.a,cross section, on line. MN, and Fig. 4 a cross section on line O P.
The tap has two passages, one g g¹ for, the flow of liquid, and the other for the
entrance of air into the receptacle. The plug A of the tap has also two passages gh²
corresponding to the passages g g' and hh. The.tap has a stop at i, against which
bears alternately the one or the other face of the notch jina washer B. secured on the
plug by a screwed nut k...
The passage g g' for the liquid terminates at a short distance, say about 4th of an
inch, behind the orifice of the passage h h for the air, while the inlet orifice e of the
latter is situated about the same distance above the outlet of the passage gg. The
lower end of the air passage is of crescent shape as shewn at Fig. 3, and it
gradually parrows up to the plug passage h³, where it is of circular form, as shewn at
Fig 4.

page_text: In the modification shewn in elevation and cross section at Figs. 5 and 6, the
passage is made of a circular section throughout, and its front part is formed
externally to the passage g g instead of internally, as in the first arrangement.
Figs. 7, 8, 9, and 10 shew, respectively, a longitudinal section, an elevation, an end
view, and a cross section at X X of a gimlet tap. This consists of a gimlet having.
two passages for liquid a b, within the former of which is placed an air tube c extending
across and through the head of the gimlet in which it terminates with an orifice d.
The inner ends of the passages a and c terminate in the side of the gimlet, at and e,
so that on boring the gimlet into the cask or other wood receptacle containing liquid,
this will flow out through a, b, and air will enter at e as soon as the openings e and f
have passed through the wood. By means of this tap the liquid can be drawn off at
any desired height of a cask.
It will be seen that in all the above taps, the discharge orifice of the air passage is
situated beyond the inlet orifice of the liquid passage, while the discharge orifice of the
latter is below the inlet orifice for air; by this arrangement of the orifices the two
currents of liquid and air, flowing in opposite directions, do not interfere with each
other, and, if in filling bottles with the tap Figs. 1 to 6, the nozzle of this be inserted
into the neck of the bottle until the orifice e of the air passage is at the exact level to
which it is desired to fill the bottle, the flow of liquid will cease as soon as the liquid
has risen to that level so as to close the orifice e.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved construction of vent taps herein described with reference to
Figs. 1 to 6 of the drawings wherein the discharge orifice of the air passage is
situated beyond the inlet orifice of the liquid passage, while the discharge orifice of
the latter is situated below the inlet orifice of the air passage, so that the flow of
liquid does not interfere with the flow of air, and is automatically stopped when the
level of the liquid drawn closes the inlet orifice of the air passage.
2. The combination with gimlet taps of a separate passage for the inlet of air, sub-
stantially as herein described.
C
3. The improved construction of gimlet tap herein described with reference to
Figs. 7 to 10, wherein an air tube c is situated in the passage for liquid a, b, the one
end being made to pass through the head of the gimlet, while the other end is bent
up and has its orifice situated beyond the orifice of the air passage.
