GEORGE JAMES CHAMBERS 74 Harleyford Road Kennington S.E. Pottery
Manager do hereby declare the nature of this invention to be as follows:-
In order to facilitate the emptying of bottles, jars, barrels & the like vessels
whose contents are emptied either from the mouth or drawn off through a tap, I
make the following improvements.
In vessels which have a small neck & mouth such as bottles & jars & whose
contents are emptied either from the mouth or drawn off through a tap, I make
one or more vent-holes in the said neck and in any convenient position & terminating
just below the cork-hole.
These vent holes are covered externally & rendered airtight by means of an
elastic band which completely encircles the neck, an arrangement is made in con-
nection with this band by which a slight pressure of the hand will open it in the
vicinity of the vent hole thereby forming an open recess for the admission of air
into the vessel while it is being emptied, after which by releasing the pressure upon
the band it will resume its former airtight position.
Another arrangement (& applicable only where a tap is used) is a removable
airpipe which will connect the vent hole in the neck of the vessel with a valve
near the tap, making the venting automatic by the aid of the key of the tap.
For barrels & such vessels as are not made with a neck and are emptied
through a tap I make a hollow venting arrangement the airholes of which are
operated upon by an elastic band similar to the one described in the bottle-neck.

COMPLETE SPECIFICATION.
Improvements in and connected with Venting Bottles, Jars, Barrels,
and the like Vessels.
I, GEORGE JAMES CHAMBERS of 74 Harleyford Road Kennington in the
County of Surrey Pottery Manager 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:-
In order to facilitate the emptying of bottles, jars, barrels, and the like vessels
whose contents are emptied either from the mouth or drawn off through a tap I
make the following improvements.
In vessels which have a small neck and mouth such as bottles and jars and whose
a tap make
contents are emptied either from the mouth or drawn off through
one or more vent-holes in the said neck and in any convenient position and
terminating just below the corkhole.
These vent holes are covered externally and rendered airtight by means of an
elastic band which completely encircles the neck and an arrangement is made in
connection with this band by which a slight pressure of the hand will open it in the
vicinity of the vent hole thereby forming an opening or recess for the admission of
air into the vessel while it is being emptied after which by relaxing the pressure
the band will resume its former airtight position.
Another arrangement (and applicable only where a tap is used) comprises an

page_text: airpipe or conduit which connects the vent hole in the neck of the vessel with a
near the top making the renting automatic by the aid of the key of the tap.
For barrels and such vessels as are or are not made with a neck and are designed
to be emptied through a tap I make a hollow renting arrangement, the airholes of
which are normally closed by an elastic band similar to the one described in the
bottle neck.

And in order that the said invention may be more clearly understood and readily
carried into effect i will proceed aided by the accompanying drawings
describe the same.
Carrie mio enect 3 win proceed and the accompanying
describe the same.

venting device or valve adapted to be automatically acted upon thereby.
Figure 15 is a side elevation of the hollow venting device or valve separately.
Figure 16 is a sectional plan thereof.
Figure 17 is a front elevation thereof.
Figures 18, 19, and 20 are similar views of a slightly modified form of venting
device or valve.
Figure 21 is an elevation partly in section of a modified form of stone jar or barrel
fitted with a hollow venting device or valve similar to that shown in connection
with Figures 14, 15, 16, and 17, and
Figure 22 is a plan thereof partly in section.
In the several figures of the drawings like parts are indicated by similar letters
of reference.
Referring to Figures 1 to 4 a represents a stone bottle or jar which is formed
with a mouth a' furnished with a screw stopper a¹* or it might be any other form
of stopper by means of which the mouth a' may be closed after the vessel a is
filled therethrough, and a represents a tubular boss formed on the bottle a and
closed by means of a cork a into and through which is screwed a draw off tap c.
The bottle neck is formed with two or it might be any other convenient number
of vent holes or air ways a' therethrough located in any convenient position just
below the corkhole and over these air ways is stretched an india rubber band in
such manner that it will normally cover the air ways a³ and constitute a valve to
close the vent.
In connection with the india rubber band a lever is employed which is mounted
upon a centre of motion formed by a pin * passing therethrough and through
corresponding holes a" formed in two nibs a fixed or formed upon the bottle neck
and the inner end ** of the lever normally occupies a recess as provided in the

page_text: neck of the bottle beneath the india rubber band whilst the enlarged outer
end of the lever is by a cord or other suitable_connection **** connected
with the tape so that as the tap c is turned on in order to draw off some of the
contents of the bottle a the hand of the operator or the key c¹ of the tap may be
caused to press against the connection **** and thus through the lever braise
the india rubber band in the vicinity of the vent holes a³ and permit a supply of
air to enter the bottle a whilst upon turning off the tap the connection ****
may be released when the parts will resume their normal positions and the india
rubber band b will again close the vent holes as in an air tight manner.
In bottles which are intended to be emptied through the mouth a' and which are
consequently not fitted to receive taps the connection **** is dispensed with
and the india rubber band bis raised by the hand of the operator pressing directly
upon the enlarged end *** of the lever in which case the vent-holes a³ and
lever might with advantage be placed near the handle of the bottle.
In the arrangement represented at Figures 5 to 11 a hollow venting device is
fixed upon the neck of the bottle a and is formed with an air way 62 communicating
with an air hole as formed in the bottle and the air way of the hollow venting
device leads to one side thereof where it is normally closed by an india rubber
band in a similar manner, to that described with respect to Figures 1 to 4.
In this example the lever which is a duplex lever is loosely fitted into slots
grooves or recesses formed in the venting device * and thus normally lies snugly
Beneath the india rubber band b and instead of being mounted upon a pin passing
through its centre it is formed with returned ends * which take into offsets **
of the grooves or recesses 6 and thus prevent the lever becoming accidentally
displaced whilst at the same time they form fulcra upon which the lever b¹ is capable
of rocking so that by pressing forward the upper part *** of the lever by means
of a connection to a tap or by direct pressure of the hand the india rubber band
may be displaced from the air way as hereinbefore explained.
In the arrangement represented at. Figures 12 and 13 the hollow venting device *
is provided with a tapered screw thread to adapt it to be screwed into a hole
bushed with cork or other suitable material or into a hole formed in a wooden vessel
but in other respects it is similar to the device lastly hereinbefore described.
In the arrangement represented at Figures 14 to 17 which is specially intended
for use in connection with a tap, an air way in the neck of the bottle is continued
to or near to the junction of the neck with the body of the bottle within a bulge or
rib a formed on the bottle neck and the air way as is by a removeable metal or
other pipe a** connected with a hollow boss a' formed upon the bottle and fitted
with a bushing a* of cork into which is screwed a hollow venting device or valve b*.
The hollow venting device or valve is very similar to that lastly hereinbefore
described but in this example the duplex lever is mounted upon a pin or axis of
motion carried by the device and the upper ends of the lever are
received into grooves or recesses 3 in the device whilst its lower end *** is
enlarged and curved in order that the key c¹ of the tape may act thereon to press
it inward and thus cause the opposite ends of the lever i to displace the india
rubber band and permit air to pass into the bottle.
The venting device or valve represented at Figures 18 to 20 is very similar
to that lastly herein before described but is somewhat different in shape the seat
for the india rubber band being horizontal instead of vertical whilst the lever ↳¹
is cranked in order to bring its enlarged end 81*** into position to be acted upon
by the key of the tap c.
The arrangement represented at Figures 21 and 22 is identical with that shown
at Figure 14 except that the removeable pipe a³** is dispensed with and the bulge
or rib formed upon the vessel is continued down to the hollow boss a².
*
In lieu of the venting device or valve shown in connection with Figures 14, 21,
and 22 I may employ any other suitable form of valve adapted to be actuated by
the key of the tap.
Although I have shown and described my invention in connection with stoneware

page_text: vessels would have it understood that it is equally applicable to casks and other
vessels formed of wood or other material.
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 1
claim is
1. A venting device consisting of a vent hole or holes formed in the neck of a
vessel, an india rubber band to normally cover such holes and a lever for lifting
or displacing the band in the vicinity of the air holes substantially as herein shown
and described.
2. A. hollow venting device or valve consisting of an air way, an india rubber
band to normally close such air way and a lever for lifting or displacing the band
in the vicinity of the air way substantially as herein shown and described.
3. A venting device consisting of a valve actuated by the key of a tap and an air
pipe conduit connecting the upper part of the vessel with the valve substantially
as herein shown and described.
or
