Year: 1873

page_text: LETTERS PATENT to John Redgrave and Daniel Wright, both of
Birmingham, in the County of Warwick, for the Invention of
"IMPROVEMENTS IN GLASS VESSELS AND OTHER ARTICLES TO WHICH TAPS,
STOPPERS, AND OTHER ÅTTACHMENTS ARE TO BE APPLIED.”
PROVISIONAL SPECIFICATION left by the said John Redgrave and
Daniel Wright at the Office of the Commissioners of Patents, with
their Petition, on the 18th January 1873.
We, JOHN REDGRAVE and DANIEL WRIGHT, both of Birmingham, in
the County of Warwick, do hereby declare tho nature of the said
Invention for "IMPROVEMENTS IN GLASS VESSELS AND OTHER ARTICLES TO
WHICH TAPS, STOPPERS, AND OTHER ATTACHMENTS ARE TO BE APPLIED," to be as
follows:-
Heretofore in making moulded hollow glass vessels and other hollow
articles in glass, such as vessels representing barrels, filters, or other hollow
forms for holding wines, spirits, water, or other liquids which are drawn
therefrom by a tap the hole for the insertion of the tap or other attachi-

page_text: ment has been formed by piercing the glass after the vessel is moulded,
lumps or enlargements being formed around the outside of such holes by
blowing or otherwise to increase the holding surface for the taps, pipes,
or other attachments inserted in the holes so formed. This method of
forming holes in glass vessels or other articles in glass for inserting taps,
pipes, or other attachments is attended with considerable expense, and great
risk of breaking, consequently enhancing the cost of such articles. Now
the object of our improvements is to form or leave holes or openings in
glass vessels of various kinds or other hollow or partially hollow glass
articles at the time they are moulded, and around such holes or openings
on the interior surface we form enlargements (or increase the thickness)
in order to afford sufficient surface for the insertion of taps, pipes,
stoppers, plugs, or other attachments with or without washers, the
moulds being suitably formed for this purpose.
Our improvements are applicable to the forming of holes or openings
as previously described in glass barrels, filters, lamp and other vases, or
other vessels, ink holders formed with two or more compartments,
claret, water, and other jugs, tankards, cups, hollow globes, chandilier
and lamp bodies, hollow glass fittings for various purposes, knife, door,
tea kettle, beer machine, and other handles, and a variety of other
articles in glass.
When required the holes or openings are formed with a screw thread

thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Redgrave and Daniel
Wright, Her special license that we, the said John Redgrave and Daniel
Wright, our cxecutors, administrators, and assigns, or such others as
we, the said John Redgrave and Daniel Wright, our executors, admini-
strators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN GLASS
VESSELS AND OTHER ARTICLES TO WHICH TAPS, STOPPERS, AND OTHER ATTACHMENTS
ARE TO BE APPLIED," upon the condition (amongst others) that we, the
said Jolin Redgrave and Daniel Wright, our executors or admini-
strators, by an instrument in writing under our or their hands and seals,
or under the hand and seal of one of us or them, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Offico within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Redgrave, on behalf of
myself and the said Daniel Wright, do hereby declare the nature of
the said Invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following
statement thereof, that is to say :—
Heretofore in making moulded hollow glass vessels and other hollow
articles in glass, such as vessels representing barrels, filters, or other
hollow forms for holding wines, spirits, water, or other liquids which are
drawn therefrom by a tap the hole for the insertion of the tap or other
attachment has been formed by piercing the glass after the vessel is
moulded, lumps or enlargements being formed around the outside of
such holes by blowing or otherwise to increase the holding surface for
the taps, pipes, or other attachments afterwards inserted in the holes so
formed. This method of forming holes in glass vessels or other articles
in glass for inserting taps, pipes, or other attachments is attended with
considerable expense and great risk of breaking, consequently enhancing
the cost of such articles. Now the object of our improvements is to
form or leave holes or openings in glass vessels of various kinds or other

page_text: hollow or partially hollow glass articles at the time they are moulded,
and around such holes or openings on the interior we form enlargements
(or increase the thickness) in order to afford sufficient holding surface
for the insertion of taps, pipes, stoppers, plugs, or other attachments
with or without washers, the moulds being suitably formed for this
purpose.
Our improvements are applicable to the forming of holes or openings
as previously described in glass barrels, filters, lamp and other vases, or
other vessels, ink holders formed with two or more compartments,
claret, water, and other jugs, tankards, cups, hollow globes, chandelier
and lamp bodies, hollow glass fittings for various purposes, knife, door,
tea kettle, beer machine, and other handles, and a variety of other
articles in glass.
And in order that our improvements may be clearly understood, and
readily performed or carried into practice, we will proceed to describe
the Drawings hereunto annexed, which show the manner in which our
improvements are applied in forming holes in glass barrels, vases, and
other hollow glass articles for receiving taps, pipes, stoppers, and other
attachments.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side view, and Figure 2 a vertical section of a glass
vessel representing a barrel A for holding wine or other liquids, and an
inner glass vessel A' to contain ice as a cooler or refrigerator, or the
inner vessel may be arranged as a filter for filtering purposes. a, a, are
enlargements formed around the inner surface of the holes in which the
taps and supply pipe b, b, are inserted, the moulds into which the
molten glass is forced being suitably formed for producing the enlarged
or thickened surfaces a, a.
A mould maker will readily understand from the previous description,
aided by the Drawings, in what manner the mould should be con-
structed for producing the holes with enlargements a, a, or an addi-
tional thickness of glass where such increased thickness is required for
the insertion of taps, pipes, stoppers, or other attachments in accordance
with our improvements.
In some cases for convenience in forming the mould and moulding the
glass we cause the inner ends of the holes or thickened parts to be closed
by a thickness of glass when moulded, which can be readily removed or

page_text: attachment.
Figures 3 and 4 show two views of a glass vase, the holes or recesses
by which the handles b, b, or other ornamental parts are attached thereto
being formed with enlargements a, a, by increasing the thickness of the
glass at those parts as previously described in accordance with our
improvements.
Figures 5 and 6 shew two views of a central hollow glass ornament
or body for a chandilier, the holes or openings for receiving the ends
of the branches or other attachments b, b, being formed with enlarge-
ments a, a, by increasing the thickness of the glass around the holes or
openings in the process of moulding in accordance with our im-
provements.
Figures 7 and 8 shew two views of a moulded glass tankard or
drinking vessel formed with enlarged portions a, a, in accordance with
our improvements for attaching the handle thereto as shown.
Figures 9 and 10 shew two views of a moulded vase, oil or spirit
vessel for a table or other lamp, the hole for receiving the stopper being
formed with an enlargement a, as previously described, in accordance
with our improvements.
Figures 11 and 12 show two views of a moulded spherical hollow
glass ornament having enlargements a, a, moulded therein in accord-
ance with our improvements for receiving ornamental or other
attachments.
In like manner other hollow glass articles, such as ink holders, knife,
door, kettle, beer machine, and other glass handles may be formed with
enlargements a, a, in accordance with our improvements for receiving
metal or other attachments or ornaments.
When required the holes or openings are formed with a screw thread
to receive screw attachments.
Glass taps, pipes, or stoppers may likewise be formed in this manner
in accordance with our Invention for the insertion of a plug of glass or
other materal either with or without washers.
Having thus described the nature of our improvements, and the manner
of performing or carrying the same into practice, what we claim is, the

page_text: improved construction of moulded hollow glass vessels and other
articles by forming them in the process of moulding with holes or
openings having enlarged or thickened surfaces of glass a, a, around
them for receiving taps, stoppers, and other attachments, substantially as
and for the purposes herein-before described and shown in the Drawings
hereunto annexed.
In witness whereof, I the said John Redgrave, have hereunto set
my hand and seal, this Twelfth day of July, in the year of our
Lord One thousand eight hundred and seventy-three.
