PROVISIONAL SPECIFICATION.
Improvements relating to Bung Flanges for Brewery Casks.
I, MICHAEL HANLEY of 8 Christ-Church Place, Dublin, Ireland, Brewery
Labourer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object an improved method of flanging brewery casks
in a more permanent and effectual manner than hitherto.
According to the present method the metal flange which is threaded on its outer
periphery is simply screwed direct into an aperture formed in the shell of the cask.
This method in the ordinary course of wear is insecure inasmuch as owing to the
frequent driving home of the bung or stopper the flange is disturbed in its seat,
and leakage is the result.
My invention is designed to overcome this defect and to this end I take, in the
first instance a ilange as at present used and instead of threading it on its outer
periphery 1 form a female screw thread on its inner periphery.
This flange I insert in the aperture from the interior of the cask to such an
extent as to provide a certain interval of wood between its end and the outer
surface of the shell for the purpose presently described.
I next take a second flange of suitable diameter to enter the first described
flange, and provided on its outer periphery with one or two deep male screw
threads, and terminating with a series of finer threads.
This flange is screwed by means of its finer screw thread into the first described
flange from the outer side of the cask while the deeper threads engage in the
interval of wood above provided for.
By this arrangement a complete flange is produced and the usual hammering in
driving home the bung or stopper will not disturbe same or cause leakage.
It is obvious that both flanges are held firmly by the engagement of one with
the other while any tendency to leak is prevented by part of the outer flange
engaging with an interval of wood as described.

· COMPLETE SPECIFICATION..
Improvements relating to Bung Flanges for Brewery Casks.
I, MICHAEL HANLEY of 8 Christ-Church Place, Dublin, Ireland, Brewery
Labourer, do declare the nature of this invention and in what manner the same
s to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention has for its object an improved method of flanging brewery casks
na more permanent and effectual manner than hitherto.

page_text: According to the present method the metal flange, which is threaded on its outer
periphery, is simply screwed direct into an aperture formed in the shell of the
cask.
This method in the ordinary course of wear is insecure inasmuch as owing to the
frequent driving home of the bung, or stopper, the flange is disturbed in its seat,
and leakage is the result.
My invention is designed to overcome this defect and to this end I take, in the
first instance, a flange as at present used and instead of threading it on its outer
periphery 1 form a female screw thread on its inner periphery.
This flange I insert in the aperture from the interior of the cask, to such an
extent as to provide a certain interval of wood between its end and the outer
surface of the shell for the purpose presently described:
I next take a second flange of suitable diameter to enter the first described
flange, and provided on its outer periphery with two suitable male screw threads.
This flange is screwed into the first described flange from the outer side of
the cask while portion of its threads engage in the interval of wood above
provided for.
The accompanying drawings will enable my said invention to be more readily
understood and carried into practice.
Fig. 1. is a cross section representing portion of a cask, and the flange consisting
of pieces A and B in position, and, Fig. 2. is a plan view of the inner surface
of the first described flange A, or that inserted from the interior of the cask.
It will be observed that portion of the screw formed on the flange B engages
with the wood of the cask as above specified.
By the use of my invention as herein described and illustrated a complete
flange is provided for brewery casks and the usual hammering, in the act of driving
home the bung or stopper will not cause any disturbance, or leakage.
It is obvious that both portions of the flange are held firmly together by the
engagement of one with the other, while any tendency to leakage is prevented
by part of the flange B engaging with an interval of wood as shewn in Fig. 1.
Webs or spuds C. C. are provided on flange A to prevent same turning in the
act of securing to the cask.
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 I
claim is :-
First. In brewery casks, the use and application of a bung flange consisting of
two parts: A and B constructed and arranged substantially as herein described and
illustrated in the accompanying drawings.
Second. The use and application of a bung flange constructed as herein
described, in combination with brewery casks for the purpose specified and set
forth.
