PROVISIONAL SPECIFICATION.
A New or Improved Method of Applying the Government Stamp or
Mark to Glass Vessels or Measures.
I EDWARD MOORE of Tyne Flint Glass Works South Shields in the County of
Durham Pressed Glass Manufacturer do hereby declare the nature of this invention
to be as follows:-
My invention relates to glass vessels or measures which are of a given capacity
and upon which it is necessary to mark in a permanent manner the government
stamp or proof mark by means of which such capacity is authenticated and
my invention consists in a
new or improved method of applying said mark to
such vessels.
According to the method of manufacture hitherto employed the mark has been
applied to the vessel by processes such as engraving or biting in by means of acid
or by the aid of the sand blast but such processes have necessarily considerably added
to the cost of production of the article.
Now according to my invention I cast impress or form the stamp or mark
in or upon the side of the body of the vessel in the position required by the
government in the act of forming the vessel in the mould and without any additional
operation.
For this purpose I engrave the mark or stamp in the side of the plunger or it might
be in the mould as may be convenient so that in the act of pressing the article
the mark or stamp will be clearly and sharply impressed or imprinted thereon in a
permanent manner.
By these means I am enabled to fulfil the requirements of the government in a
better manner and at much less cost than heretofore.

COMPLETE SPECIFICATION.
A New or Improved Method of Applying the Government Stamp or
Mark to Glass Vessels or Measures.
I EDWARD MOORE of Tyne Flint Glass Works South Shields in the County of
Durham Pressed Glass Manufacturer 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 :-
My Invention relates to glass vessels or measures which are of a given
capacity and upon which it is necessary to mark in a permanent manner the
Government stamp or proof mark by means of which such capacity is authenticated
and my invention consists in a new or improved method of applying said mark
to such vessels.
According to the methods of manufacture hitherto employed the mark has been
applied to the vessel by processes such as engraving or biting in by means of acid or
by the aid of the sand blast but such processes have necessarily considerably added
to the cost of production of the article and moreover the mark or stamp when so
produced failed to prove permanent or easy of observation.
Now according to my invention I cast impress or form the stamp or mark
in or upon the side of the body of the vessel in the position required by the

page_text: Government and in the act of forming the vessel in the mould by pressure in the
well known manner of making articles of pressed glass and without any additional
operation.
For this purpose I engrave the mark or stamp in or on the side of the plunger
or it might be in or on the body of the mould as may be convenient so that in the
act of pressing the article the mark or stamp will be clearly and sharply impressed or
imprinted thereon or therein in a distinctive and permanent manner.
And in order that the said Invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully to
describe the same.
Figure 1. represents a vertical section of a mould showing the plunger in position
therein such plunger having the Government stamp or mark engraved therein in
accordance with my invention.
Figure 2. represents a glass vessel or measure made in such mould.
Figure 3. represents a vertical section of part of the plunger taken through the
stamp or mark and drawn to an enlarged scale.
Figure 4 represents a vertical section of such part taken through the letter T of
the word "pint" and
Figure 5. is a face view thereof.

Figure 6. represents one half of a mould without the plunger illustrating.
modification in which the mould has the Government stamp or mark applied
thereto, and
Figure 7. represents a glass vessel or measure made in such mould.
In the several figures like parts are indicated by similar letters of reference.
a represents the mould represents the plunger c represents the die of the
Government mark or stamp d represents the glass vessel or measure and d³ represents
the Government stamp or mark thereon.
In the arrangement represented at Figures 1 to 5 a solid mould a is employed and
the die of the Government mark or stamp c is engraved in the side of the plunger b
so as to produce the mark or stamp d¹ in relief upon the inner face of the glass
vessel or measure d.
In order that the plunger b may readily clear itself from the glass vessel or
measure d after pressing it into form in the mould a I form the engraved lines of the
letters or characters constituting the mark e shallower or tapered towards the lower
part of such mark so that no appreciable shoulder or obstruction may be offered to
the withdrawal of the plunger b.
In the example given at Figures 6 and 7 the mark or stamp c is engraved in the
face or body of the mould a so as to produce the mark or stamp d' in relief upon the
outer face of the glass vessel or measure d and in this case in lieu of tapering
the lines of the letters or characters constituting the die c the mould a is divided or
formed in two or it might be more parts capable of easy separation in order
to facilitate or permit the removal of the finished glass vessel or
therofrom.
measure d
If desired in lieu of forming the die or mark c in intaglio in the face or body of
the mould a or plunger b as herein before shown and described it may be formed
thereon in relief so as to produce the stamp or mark d' in intaglio upon the finished
glass vessel or measure d.
Although in the drawings I have represented the half pint Government stamp or
mark and a corresponding glass vessel or measure having such mark or stamp
applied thereto according to my invention I would have it understood that I do not
confine myself thereto as my invention is equally applicable to glass vessels or
measures of any other denomination or capacity.

page_text: 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 :-
The method of applying the Government stamp or mark to glass vessels or
measures consisting in impressing or forming such mark therein or thereon during
the ordinary process of pressing or forming the article substantially as herein shown
and described.
