Year: 1874

page_text: LETTERS PATENT to Lauchlan Rose, Lime Juice Merchant, Leith,
and James Brown, Glass Cutter, 14, Arthur St., Edinburgh, both
in the County of Edinburgh, for the Invention of " AN IMPROVED
TOOL OR SHEARS TO PRODUCE AN OUTSIDE SCREW ON THE NECK OF
BOTTLES,"
Scaled the 9th October 1874, and dated the 11th April 1874.
PROVISIONAL SPECIFICATION left by the said Lauchlan Rose and
James Brown at the Office of the Commissioners of Patents, with
their Petition, on the 11th April 1874.
We, LAUCHLAN ROSE, Lime Juice Merchant, Leith, and JAMES
BROWN, Glass Cutter, 14, Arthur St., Edinburgh, both in the County
of Edinburgh, do hereby declare the nature of the said Invention
for "AN IMPROVED TOOL OR SHEARS TO PRODUCE AN OUTSIDE SCREW ON THE NECK
OF BOTTLES," to be as follows:-
The tool or shears above referred to for making an outside screw on

page_text: the necks of bottles, consists in a cup-shaped circular mould on the inner
sides or surfaces of which have produced thereon the screw to be produced
on the necks of the bottles and of the required size. This cap or mould
is attached to a tube or casing (usually about six inches long) inside of
which tube or casing is placed a plunger of the size required for the
inside of neck of the bottle, such plunger being provided with a spring
which is attached to the tool or shears, and so that the workman can
press the spring at pleasure, and this acting upon the plunger forces it
into the cup or mould, by which pressure the glass the cup contains is
forced into the thread of the screw, after which on withdrawing the
pressure upon the spring the plunger recedes to its normal position
inside of the tube or casing when the bottle is to be unscrewed from the
cup or mould.
SPECIFICATION in pursuance of the conditions of the Lettors Patent,
filed by the said Lauchlan Rose and James Brown in the Great
Seal Patent Office on the 9th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, LAUCHLAN
ROSE, Lime Juice Merchant, Leith, and JAMES BROWN, Glass Cutter,
14, Arthur Street, Edinburgh, both in the County of Edinburgh, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of April, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Lauchlan Rose and James Brown,
Her special licence that we, the said Lauchlan Rose and James Brown,
our executors, administrators, and assigns, or such others as we, the said
Lauchlan Rose and James Brown, our executors, administrators, 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 "AN IMPROVED TOOL OR SHEARS TO Produce an
OUTSIDE SCREW ON THE NECK OF BOTTLES," upon the condition (amongst others)

page_text: that we, the said Lauchlan Rose and James Brown, our executors or
administrators, by an instrument in writing under our, or their, or one
of their hands and seals, 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
Office within six calendar months next and immediately after the date of
the said Letters Patent.
NOW KNOW YE, that we, the said Lauchlan Rose and James Brown,
do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object and intention of this Invention is to have a tool or shears
for making an outside screw on the necks of bottles. The said tool or
shears consists in a cup-shaped circular mould, the inner sides or surfaces
of which have produced thereon the screw to be produced on the necks
of the bottles, and of the required size for the necks of such bottles.
This cup or mould is attached to a tube or casing (usually about six
inches long) inside of which tube or casing is placed a plunger of the
size required for the inside of the neck of the bottle, such plunger being
provided with a spring which is attached to the tool or shears, and so
that the workman can press the spring at pleasure, and this acting upon
the plunger forces it into the cup or mould, by which pressure the glass
the cup contains is forced into the thread of the screw, after which upon
withdrawing the pressure upon the spring, the plunger receeds to its
normal position inside of the tube or casing when the bottle is to be
unscrewed from the cup or mould.
Another form of shears consists in having the presser or plunger in
two halves, said halves being secured by pin or otherwise to the cup or
mould. To the presser or plunger the handle is attached, such handle
having a spring attachment.
The foregoing statements particularly describe and ascertain the nature
of the said Invention, and indicate in what manner the same is to be
performed or carried out in practice, and in further compliance with the
condition in the said Letters Patent contained, we will now further and
particularly describe and ascertain in what manner the same is to be

page_text: applicable for making screws on outside of necks of bottles, the mouths
of such bottles not being required of any certain diameter.
Figure 2 represents in section a form of tool or shears applicable to
bottles of fixed diameters of mouths.
:
In Figure 1, A is a cup or mould furnished with an inside screw on
sides of the required size or pitch, on upper side of said cup or mould is
screwed or fixed the tube B, such tube having a slit or opening of sufficient
length to allow the small tapered piston C working inside the tube, one
end of which tube is attached by the connecting rod D, the other end of
the rod being attached to the tool or spring E at F, which is also
attached to the tube at G. These shears or tool are represented at rest
in Fig. 1. When in use the hot metal on neck of the bottle is
pressed into the cup or mould when the tool or spring E is compressed,
thereby forcing down the piston or plunger C into the cup or mould A,
pressing the heated glass into the thread of the screw, the plunger or
piston forming a sufficient opening for the bottle mouth.
In Figure 2, A represents the cup or mould, inside of which and
attached by pin or otherwise at H works the presser or plunger I in two
halves in form of shears, the handle being provided with a spring
attachment K, which on pressing opens up the shears or tool inside of
the cup or mould, thus forcing the glass into the thread of the screw
when inserted in its heated state into the cup or mould; the pressure
on the spring being withdrawn the bottle is then unscrewed from the
cup.
Having now particularly described and ascertained the nature and
object of our said. Invention, and in what manner the same is to be
performed and carried out in practice, we hereby declare that we claim
the herein described Invention for "An Improved Tool or Shears to
Produce an Outside Screw on the Neck of Bottles," as the same is

page_text: herein-before set forth and described and illustrated by the Drawings
accompanying these Presents.
In witness whereof, we, the said Lauchlan Rose and James Brown,
have hereunto set our hands and scals, this Sixth day of October,
in the year of our Lord One thousand eight hundred and seventy-
four.
Witness,
JOHN MORRIS,
