PROVISIONAL SPECIFICATION.
Improvements in the Manufacture or Construction of Metallic
Casks or Drums for Containing Mineral and other Oils or
the like.
I, RICHARD ELIHU DICKINSON, of The Bowling Iron Company, Limited,
Bradford, in the County of York, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in the manufacture or construction of
metallic casks or drums for containing mineral and other oils or the like and its
object is to facilitate welding the bung seat to the sheet metal of the cask.
For this purpose I employ a bung seat having an external flange or projection
surrounding it. Around the edge this flange is the same thickness, or approxi-
mately the same thickness, as the sheet metal forming the shell of the cask or
drum. A hole is made in the sheet metal of the shell slightly larger than the said
flange to allow for expansion of the metal when raised to a welding heat. The
bung is placed in position in this hole and the said flange electrically welded to
the shell together with small pieces of metal placed over the joint.
I prefer to employ bung seats stamped to form and in this case, to avoid the
necessity of "facing the seat, I form an annular recess in the seat adapted to
receive a lead, leather or other suitable washer, and I form an annular projection
on the bung adapted to bear upon said washer to form the joint.
Dated this 24th day of February 1894.

COMPLETE SPECIFICATION.
Improvements in the Manufacture or Construction of Metallic
Casks or Drums for Containing Mineral and other Oils or
the like.
I, RICHARD ELIHU DICKINSON, of The Bowling Iron Company, Limited,
Bradford, in the County of York, 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 :-
This invention relates to improvements in the manufacture or construction of
metallic casks or drums for containing mineral and other oils or the like, and its
object is to facilitate welding the bung seat to the sheet metal of the cask.
For this purpose I employ a bung seat having an external flange or projection
surrounding it. Around the edge this flange is the same thickness, or approxi-
mately the same thickness, as the sheet metal forming the shell of the cask or
drum. A hole is made in the sheet metal of the shell slightly larger than the
said flange to allow for expansion of the metal when raised to a welding heat.
The bung is placed in position in this hole and the said Hange electrically welded
to the shell together with small pieces of metal placed over the joint.
In the accompanying sheet of drawings forming a part of this Specification,
Figure 1, represents a diametrical section of a bung and bung seat in which the
latter is provided with a welding Hange in accordance with my invention.
Figure 2, is a plan view of the same.

page_text: Figure 3, represents a separate diametrical section of a bung seat adapted to be
secured in the head or end of a cask.
The welding flange is formed around the external periphery of the rim F
of the bung seat and this flange is made approximately to the same curve as the
exterior of the cask. In the case of bung seats for the heads of casks the
flange N is preferably made flat and as shown in Figure 2.
Instead of the form of seat shown in my Specification No. 19,894, dated the
23rd day of October 1893 to avoid accurately facing the seat
may form an
annular recess X in the seat D adapted to receive a lead, leather or other suitable
washer W and I form an annular projection P on the bung adapted to bear upon
said washer to form the joint.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:
1. A bung seat for metallic casks having an external flange surrounding it
approximately the same thickness as the shell of the cask, substantially as herein
shown and described and for the purpose specified.
2. A. bung seat for metallic casks having an external flange N and an annular
recess adapted to receive a washer upon which an annular projection on the bung
is arranged to bear to form the joint, substantially as herein shown and described.
Dated this 20th day of July 1894.
