An Improved Drinking Tankard.
HENRY OBORNE Box 99 John Street Barnsbury, N. Metal Worker, do hereby
declare the nature of this invention to be as follows:-
A grooved steel drinking tankard with tinned steel handle fixed on groove, and
stamped sunk bottom. Stamped imperial measure by L.C.C. in sizes pint,
1 pint & 1 quart for the purpose of drinking tankards. The objects of the
invention is to take the place of pewter, electro or nickle plated tankards and
glasses. Pewter gets out of shape, thus short measure gets stolen because a
valuable metal, the above invention as a metal is valuless, thus prevents theft.
Electro & nickle plated tankards when worn are unwholesome as the metals are of
a cankerous kind. The imperial plated steel tankard is made in the most whole-
some of all common metals being tin & steel, keeps its shape and is unbreakable
thus taking the place of glass. A long wanted tankard for the public and the
publican.

1, HENRY OBORNE Box, of 99 John Street, Barnsbury, London, N., Metal
Worker, 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 a novel construction of tankards such as are used by
hotels, publicans, and others for bar and general drinking purposes in supplying
customers.
1 make my tankards of tinned steel or of steel plate and tin them afterwards,
steel being very strong and not liable to damage from the vagaries of customers,
besides ensuring full capacity of such tankards and less liability to be stolen, to all
of which the ordinary pewter or soft white metal taukards are subject.
For the purpose of my invention, I roll or otherwise prepare a steel plate
previously tinned or not on a suitable mandrel to form a tube of a conical or other
straight sided shape, and I bend the longer edges into a kind of hook and eye
looping or grooving which when placed within each other constitute an outside rib
and a sound seam to which the handle, also of tinned steel of the required
curvature and shape provided with inwardly formed tails, is attached.
I make a reverse cup shape of bottom also of tinued steel the flange of said cup
being downwardly and so shaped that it exactly fits the lower part of the tankard
into which it is pressed until the edge corresponds to the bottom edge of the body
of the tankard and increases the thickness at that part to resist rough usage, this
extra thickness coupled with the great strength imparted by the rib which is also
present at the bottom protects that part of the tankard most liable to blows or
knocks when carelessly and roughly put down.

Figure 3 detached view of my grooved meeting parts on an enlarged scale.
A the body here shown of cone or angle sided shape. B, an outwardly turned
back lip from one of the longer edges of the body A. C, an outwardly bent and
inwardly curved lip of the other longer edge of the body A, the groovings of
which when the two lips B, C, are interlocked form an outside rib from top to
bottom of the body A, which lips B, C, are put into close contact by pressure to
make the side seam liquid tight, the pressure compelling the inner surfaces to be
flush and nearly smooth with the other inside part and the rib projecting outside.
Dis the bottom. E the flange thereof which exactly fits the lower part of the
body A, the bottom edge of said flange E being level and coinciding with the
bottom edge of the body A.
F is the handle of tinned steel, and G, G, are the tails of the handle which are
soldered to the rib of the body by pure tin, the inner and outer crevices of the rib
portion being also soldered by pure tin which not only ensures the positive attach-
ment of one part to the other but makes the seams liquid tight.
Among the advantages derived from my invention will be found, strength
combined with lightness, neatness, cleanliness, freedom of injurious action from
liquids, there being also nothing in the tinned seams that could affect the highest
brand of malt liquors as with brazed seams of other tankards now in use with flush
seams.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The manufacture of taukards from sheet steel tinned on both sides, grooved and
interlocked at the meeting seam producing exterior rib, stamped flauged bottom
with edge coinciding with that of body, and tinned steel handle, as and in the
manner described and shown for the purpose set forth.
