Improvements in Tankards or Drinking Vessels.
I, JAMES HENRY DRAKE, Engineer, of 1, Castle Terrace, Southend-on-Sea, in
the County. of Essex, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to improvements in the construction of tankards or
drinking cups, such as are used in public houses, and other places to supply cus-
tomers with beer or other drinks; it has for its object the economical production
of a vessel, which will be of such rigid form, that it will not be liable to become
indented or distorted, as in the case with those formed in the usual manner.
In carrying out my invention I employ sheet steel, which has been previously
tinned on both sides, and I cut therefrom a blank of the required size. I employ
male & female dies, for the purpose of stamping the said blank into a form suit-
able for its being subsequently spun to the requisite shape so that the body of
the tankard, is formed out of one piece of metal. I cause a depression to be
stamped or spun into the bottom so that the tankard will stand upon the outer rim;
when the said tankard body has been thus formed, I cause it to be re-tinned, which
may be done either by the usual method of dipping into a bath of molten metal,
or by placing the tankard body in a bath of metallic salts, and causing the tin
to be deposited by electrolysis. When the deposit of tin has thus been made I
place the tankard body in an inside and outside chuck respectively, so that the
internal and external surface, of the body can be rapidly revolved and burnished.
I form a handle of suitable metal and attach same to the body by solder, revitting
or other equivalent means.
It will be seen that by employing thin homogeneous steel for the manufacturing
of the body, extreme lightness is obtained, whilst liability to indentation and dis-
tortion is prevented.

page_text: invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
My invention has reference to improvements in the construction of tankards or
drinking cups, such as are used in public houses, and other places to supply cus-
tomers with beer or other drinks; it has for its object the economical production,
of a vessel which will be of such rigid form, that it will not be liable to become
indented or distorted, as is the case with those formed in the usual manner.
In carrying out my invention I employ sheet steel, which has been previously
tinned on both sides, and I cut therefrom a blank of the required size. I employ
male and female dies, for the purpose of stamping the said blank into a form suit-
able for its being subsequently spun to the requisite shape so that the body of
the tankard, is formed out of one piece of metal. I cause a depression to be
stamped or spun in the bottom so that the tankard will stand upon the outer rim.
When the said tankard body has been thus formed I cause it to be retinned, which
may be done either by the usual method of dipping into a bath of molten metal,
or by placing the tankard body in a bath of metallic salts and causing the tin
to be deposited by electrolysis. When the deposit of tin has thus been made I
place the tankard body in an inside and outside chuck respectively, so that the
internal and external surface of the body can be rapidly revolved and burnished.
I form a handle of suitable metal and attach same to the body by solder, rivetting
or other equivalent means.
It will be seen that by employing thin homogenous steel for the manufacturing
of the body extreme lightness is obtained whilst liability to indentation and dis-
tortion is prevented.
!
In the accompanying drawing which illustrates in vertical section one form of
tankard constructed according to this invention; -
A is the body of the tankard formed as hereinbefore described from one piece
of metal and having the bottom dished as at B. C is a handle formed separately
and secured to the body A by any convenient means.
It is found that the spinning may generally be dispensed with and the body
of the tankard plated after the stamping process. The plating is not absolutely
essential but is desirable as the tinning on the sheet steel is liable to damage dur-
ing the stamping of the body.
--
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:-
1. A stamped steel tankard.
2. A stamped steel tankard having a dished bottom as at B.
3. A tankard made of stamped steel with a separate handle secured to it.
4. The herein described manufacture of a tankard by stamping spinning and
plating by dipping or electro-deposition.
