A New or Improved Method of and Means for Venting Casks
or other Vessels.
I ROBERT LOUND CRAVEN of Church Lane Kings Lynn in the County of
Norfolk Brewer do hereby declare the nature of this invention to be as follows:-
A cylindrical tube and peg of metal. The cylindrical tube having at one end a
flange or projecting rim, and upon its exterior below the flange a thread or worm
for fixing or screwing the tube into a cask or other vessel. The bore of the tube
at its flanged end is splayed or countersunk. Across the upper surface of the
flange is a groove or grooves making a channel or channels to the countersunk
mouth of tube for the double purpose of holding a tool to screw the tube into
place and of admitting air beneath the flat side of collar on the hereinafter
described peg.
The peg or rod is of such dimensions as to loosely fit into the tube and has at
about half its length or middle a circular collar one side of which is flat and
projects sufficiently to cover the countersunk mouth of tube when the mouth is so
covered air can pass by means of the groove or grooves and the space caused by
the loose fitting of the peg. The other side of collar on the peg is conically shaped
to fit the countersinking of the tube and when so fitted makes an airtight joint.
When not in use as a vent the tube is closed by a wooden plug.
When required to use the tube the wooden plug is driven into the vessel by
using the metal peg as a punch.
Dated this 13th day of June 1895.
COMPLETE DIECIFICATION.
A New or Improved Method of and Means for Venting Casks
or other Vessels.
I ROBERT LOUND CRAVEN of Church Lane Kings Lynn in the County of
Norfolk Brewer 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 :-
A cylindrical tube and peg of such material as may be suitable for fluids in
contact therewith.
The cylindrical tube having at one end a flange or projecting rim, and upon its
exterior below the flange a thread or worm.
The thread or worm is for fixing or
screwing the tube into a cask or other vessel or receiving a nut or plate in or on
vessels that may not be made of material suitable for making a direct fixture
thereto without such plate or nut.
The bore of the tube at the flanged end is splayed or countersunk.
Across the flanged end of the tube, is a groove or grooves, making a channel or
channels, to the countersunk mouth of the tube, for two purposes, firstly receiving a

page_text: tool, to fix or hold, the tube in place, whilst fixing or driving secondly to form a
passage beneath the flat side of the collar on the hereinafter described peg.
After the tube is fixed the bore thereof is closed or plugged with a wooden plug
or plug of some compressable material.
When it is desirable or necessary to make a passage to the contents of a vessel
whereon or in which the tube is fixed the hereinafter described peg is used as a
punch or drift to force the plug through or out of the tube, the peg may then be
placed in the tube to form an indirect air passage, or placed to form an air stop or
valve.
The peg is of such thickness as to enter loosely the tube and has at about half
its length a circular collar one side of which is flat and projects sufficiently to cover
the countersunk mouth of the tube, when the mouth is so covered a passage is
formed by means of the grooves across the end of tube and the space left by the
loose fitting of the peg. The other side of the collar on the peg is bevelled or
conically shaped to fit the countersunk mouth of the tube and when so placed or
fitted forms an air stop or valve. The peg is of sufficient length on either side of
collar to allow the plug being forced quite through the tube.
Referring to the accompanying drawings A the beforementioned peg is shown
in the two positions in which it may he placed in the bush B longitudinal grooves C
across the surface of the bush, forming the channel or channels the conical
surface D of the collar on the peg fitting the countersunk mouth or seat E.
Communication between the space F and the grooves C is opened or closed
according to the position in which the peg A is placed.
Having now particularly described and ascertained the nature of my said inveu-
tion and in what manner the same is to be performed I declare that what I
claim is
First. The improvements for venting casks and other vessels by means herein-
before described and illustrated in the accompanying drawings that is to say
making the said vent essentially in two parts namely of a bush or tubular piece B
to be screwed in or to the vessel to be vented and of a loose peg A with a collar
conical on one surface D forming a valve when placed in a seat E countersunk in
the upper part of the aforesaid bush or tubular piece.
Second. The use of the longitudinal grooves C on the surface of the aforesaid
bush or tubular piece which when the beforementioned peg is placed in the bush in
an inverted position form with the space F left in the bore by the loose fitting
spindle of the peg venting channels between the outside and inside of the vessel to
be vented.
Third. The use of the before mentioned peg as a drift or punch for displacing
the material with which the tube is plugged before the vessel receives its contents.
