I, ALBERT THOMAS HUGHES, of 27, Greville Road, Wood Street, Walthamstow,
in the County of Essex, Engineer, do hereby declare the nature of this
invention to be as follows:-
-
For the purpose of facilitating the inspection of the interiors of casks and
the like portable gas burners supplied with gas through flexible tubing are
frequently employed, the burner being fitted at the end of a length of rigid
gas pipe whereby it can be readily introduced through the bung hole into the
cask or the like so that the interior thereof will be illuminated by the gas
Hame.
With arrangements at present in use the cask or the like around the bung
hole is liable to be burnt or damaged by the flame as the burner is introduced
and withdrawn and, in the case of casks or the like which have been lined
with paraffin wax, it is found that around the bung hole, the lining is melted
off and the imperviousness of the cask thus destroyed. Now according to this
invention, the burner pipe is provided with a valve or cock adapted to normally
cut off the main supply of gas to the burner, the flame at which is kept alight
by means of a by-pass, said valve or cock being so arranged as to be opened by
pressure upon an external knob connected therewith.
In one arrangement the burner pipe is provided with a coupling piece formed
with a longitudinal gas passage therethrough one end portion of which com-
municates with the burner pipe and the other with the gas supply; it is also
formed with an angularly arranged transverse chamber that is divided by a
partition, formed with an aperture closed by a valve and so arranged as to cut
off communication between the two end portions of the longitudinal gas passage,
said end portions communicating with the transverse chamber on opposite sides
of the partition. The valve is carried by a spindle which extends through a
screw plug closing one end of the chamber, the other end of which is closed
by another screw plug between which and the valve is located a spring that
tends to shut the valve. The externally projecting end of the spindle is fitted
with a suitable knob surrounded by a fixed shield or guard that prevents the
valve being pressed open accidentally. The by-pass around the valve may be
regulated by means of a transverse screw.

I, ALBERT THOMAS HUGHES, of 27, Greville Road, Wood Street, Walthamstow,
in the County of Essex, Engineer, 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:
-
For the purpose of facilitating the inspection of the interiors of casks and
the like portable gas burners supplied with gas through flexible tubing are
frequently employed, the burner being fitted at the end of a length of rigid
gas pipe whereby it can be readily introduced through the bung hole into the
cask or the like so that the interior thereof will be illuminated by the gas
flame.
With arrangements at present in use the cask or the like around the bung
hole is liable to be burnt or damaged by the flame as the burner is introduced
and withdrawn and, in the case of casks or the like which have been lined
with paraffin wax, it is found that, around the bung hole, the lining is melted
off and the imperviousness of the cask thus destroyed. Now according to this
invention, the burner pipe is provided with a valve or cock adapted to normally
cut off the main supply of gas to the burner, the flame at which is maintained
by means of gas led thereto through a by-pass, .said valve or cock being so arranged
as to be opened by pressure upon an external knob connected therewith.
In the arrangement illustrated in the drawing, which is a central longitudinal
section, partly in elevation, the burner pipe 1 is provided with a coupling piece 2
formed with a longitudinal gas passage 3 therethrough, one end portion of which
communicates with the burner pipe I and the other with the flexible gas supply
tube 4; it is also formed with an angularly arranged transverse chamber 5 that
is divided by a partition 6, formed with an aperture 7 closed by a valve 8 and so
'arranged as to cut off communication between the two end portions of the longi-
tudinal gas passage 2, said end portions communicating with the transverse
chamber 5 on opposite sides of the partition 6, as shown. The valve 8 is
carried by a spindle 9 which extends through a screw plug or gland 10 closing
one end of the chamber 5, the other end of which is closed by another screw
plug 11 between which and the valve is located a spring 12 that tends to shut
the valve. The externally projecting end of the spindle is fitted with a suitable
knob 13 surrounded by a fixed shield or guard 14 that prevents the valve being
pressed open accidentally. The by-pass 15 around the valve may be regulated
by means of a transverse screw 16.
17 is a handle threaded on the burner pipe 1 between the coupling piece 2 and
a nose piece 18; 19 is a hook to enable the burner to be hung up when not
in use.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
For use in the inspection of the interior of casks or the like, a portable device
comprising a gas burner fitted to a length of pipe having a valve or cock
adapted to normally cut off the main supply of gas to the burner but capable of
being opened by pressure upon an external knob. connected therewith the flame

page_text: being maintained by gas led thereto through a by-pass, when the valve or cock
is closed, substantially as described and illustrated.
