Improvements in Stoppering the Tap Holes of Casks.
We PHINEAS ROTHWELL, Mechanic 12 Rastrick Street Oldham, EDWARD WILD
Warehouseman, 4 Slater Street Failsworth, and GEORGE HENRY HERBERT, Traveller
of 36 Huddersfield Road Oldham, all in the County of Lancashire, do hereby declare
the nature of our invention to be as follows:-
:-
The object of our invention is to improve the construction of flap valves applied to
the interiors of casks, in front of the tap holes, so as to be much simpler in construction,
more certain in action, and easier applicable.
Our invention consists in the first place in employing the india-rubber ring or other
packing (usually placed or fitted in front of the tap hole in the interior of a cask,
and serving as a joint), on the flap of the valve, which effects the closing of the
said hole, by reason of being under the influence of a spring, thereby dispensing
with the necessity of a plate or frame below the said flap to hold the india-rubber
ring or other packing in position over the said hole.
Our invention consists in the second place in arranging the plate of the flap
valve) by means of which and screws, the flap valve is fixed to the cask) so as to
form an extension of the said flap and not to be underneath the same, thus permitting
an easy attachment of the valve to the cask.
This we attain by fitting the said india rubber ring or packing by means of
a headed stud and screw or other suitable means, onto the underside of the said
hinged flap of the valve, so that the said india rubber ring or other suitable packing
shall bear directly over and onto the said tap hole when the said flap is forced
down by the influence of its spring.
The plate which serves to fix the flap valve to the cask is arranged so as to form
an extension of the hinged valve, thereby causing the screw holes in the same to be.
exposed and permit a ready fixing of the flap.valve.

Improvements in Stoppering the Tap Holes of Casks.
We PHINEAS ROTHWELL, Mechanic, 12 Rastrick Street Oldham, EDWARD WILD,
Warehouseman, 4 Slater Street Failsworth, and GEORGE HENRY HERBERT, Traveller,
of 36 Huddersfield Road, Oldham, all in the County of Lancashire, do hereby declare
the nature of our invention 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 our invention is to improve the construction of flap valves applied
to the interiors of casks, in front of the tap holes so as to be much simpler in
construction, more certain in action, and easier applicable.
.
And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference,
indicating like parts in the various figures.
Figs. 1 and 3 are vertical cross sections, & Figs. 2 and 4 side elevations of the
valve. Fig. 5 is a vertical cross section of the tap hole part of the barrel showing
the valve applied.
In carrying out our invention and referring to the figures generally, we fit an
india-rubber or other packing a (usually placed or fitted. in front of the tap hole b in
the interior of a cask, and serving as a joint) on the flap c of the valve, which effects
the closing of the said hole b, by reason of being under the influence of a spring d,
thereby dispensing. with the necessity of a plate or frame below the said flap to hold
the india-rubber ring or other packing a in position over the said hole b.
Onr invention consists in the second place in arranging the plate c¹ of the flap-
valve (by means of which and screws e the flap valve is fitted to the cask f, viz. its
bottom) so as to form an extension of the said flap and not to lie underneath the same,
thus permitting an easy attachment of the valve to the cask f.
a
This we attain by fitting the said india-rubber ring or packing a by means of a
headed stud g and screw or other suitable means, onto the underside of the said
hinged flap c of the valve, so that the said india rubber ring or other suitable packing
shall bear directly over and onto the said tap hole when the said flap c is forced
down by the influence of its spring d.
The flap c is hinged to the plate c¹ by forming the same respectively with two
eyes i and passing a pin through the same, on which is placed the spring d, pressing
against the flap c and plate c¹.
The plate c which serves to fix the flap valve to the cask f, viz. its bottom, is
arranged so as to form an extension of the hinged valve, thereby causing the screw
holes in the same to be exposed and permit a ready fixing of the flap valve.
The described construction of flap valve may be either attached to the bottom of
the cask f so as to open above, see Figs. 1 & 2, or below the tap hole b, see Figs. 3
& 4, and respectively dotted and full lines in Fig. 5, in the latter case however,
instead of the rubber ring or packing a fitting directly over the tap hole b, it is
arranged to bear against a plate c fitted in front of and serving to fix the valve to the
bottom of the cask f.

page_text: When tapping the cask, the tap g' is driven in in the usual manner the inner end of
which causes the flap of the valve to be removed from the tap hole b. by being either
lifted or lowered as shown in Fig. 5.
This method of fixing the flap valve will facilitate a more ready inspection of
the interior of the cask, general application, and serve for various sizes of tap
holes b.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In valves applied in the interiors of casks to the tap holes :-
1st. The general construction and combination of parts, substantially as and for
the purpose specified.
2nd. The employment of the india-rubber ring or packing a on the flap c of the
valve, substantially as and for the purpose specified.
3rd. The method of fixing the flap valve to the interior of a cask, as specified in
the preceding claims, as and for the purpose specified.
