page_text: LETTERS PATENT to Frederick Simpson, of Redhill, Reigate, for the
Invention of "AN IMPROVED MODE OF FORMING A SCREW IN THE NECKS OP
BOTTLES, JARS, AND OTHER SIMILAR VESSELS."
BOTTLES, JARS, AND OTHER SIMILAR VESSELS."
PROVISIONAL SPECIFICATION left by the said Frederick Simpson at the.
Office of the Commissioners of Patents, with his Petition, on the 9th
March 1857.
I, FREDERICK SIMPSON, of Redhill, Reigate, do hereby declare the nature
of the said Invention of "AN IMPROVED MODE OP FORMING A SCREW IN THE
NECKS OF BOTTLES, JARS, AND OTHER SIMILAR VESSELS," to be as follows:-
My Invention of an improved mode of forming a screw in the necks of
bottles, jars, and other similar vessels, consists of an instrument for readily
forming a screw inside the neck of the bottle or other vessel. The instrument
resembles to some extent the shears used for clipping wool from sheep, that is
to say, it consist of a flexible spring bent into a bowed or semi-circular form at
the upper part. To the ends of the jaws are rivetted two pieces of metal,
which are shaped to form the exterior of the neck of the bottle or other
vessel. In the centre of the spring clip is fitted a rod, the lower end of which
passes between the jaws of the clip; this end is made conical and a screw
thread formed thereon, the upper end passes through the bowed part of the
spring clip and terminates in a cross handle. The upper part of the rod is

page_text: retained in its place by a nut, and the lower by a transverse rod, in which it
turns freely. The melted glass to form the neck is placed on the central rod
and the jaws of the clip brought together to form the exterior of the neck and
press the glass into the thread of the screw. When the glass has hardened,
the metal screw is turned by means of the cross handle, and the bottle or
other vessel withdrawn, leaving a moulded screw formed inside the neck.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Simpson in the Great Seal Patent Office on the
9th September 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
SIMPSON, of Redhill, Reigate, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of March, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Frederick Simpson, Her special licence that I, the said Frederick
Simpson, my executors, administrators, and assigns, or such others as I, the
said Frederick Simpson, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 IM-
PROVED MODE OF FORMING A SCREW IN THE NECKS OF BOTTLES, JARS, AND OTHER
SIMILAR VESSELS," upon the condition (amongst others) that I, the said Frede-
rick Simpson, my executors or administrators, by an instrument in writing
under my, 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 I, the said Frederick Simpson, do hereby declare
the nature of my said 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 consists of an improvement on a former Invention secured to
me by Letters Patent, dated Twenty-first July (No. 1722), One thousand

page_text: eight hundred and fifty-six, and which consisted in securing or stopping
bottles, jars, or other vessels, by forming in the interior of the necks thereof a
cone and a screw. The neck of the bottle was to be made of a conical form,
and three, four, or more threads of a screw of an inverted V form, or other
form, were to be made above the cone. The cork being inserted and turned
in the threads of the screw, is forced into the conical sides of the neck of the
bottle, where it becomes tightly embedded, and effectually prevents the escape
of gas or liquid.
Now, my present Invention consists of a mode of forming a screw in the
neck of a bottle by means of the instrument herein-after described. This
instrument consists of a modification of the tongs or shears used for forming
the ordinary necks of bottles, that is to say, it consists of a flexible spring bent
into a bowed or semi-circular form at the upper part. To the .ends of the
jaws are rivetted two pieces of metal, which are shaped to form the exterior
of the neck of the bottle or other vessel. In the centre of the spring clip is
fitted a rod, the lower end of which passes between the jaws of the clip; this
end is made conical and a screw thread formed thereon. The upper end passes
through the bowed part of the sping clip and terminates in a cross handle. The
upper part of the rod is retained in its place by a nut, and the lower by a trans-
verse rod, in which it turns freely. The melted glass to form the neck is placed
on the central rod and the jaws of the clip brought together to form the exterior
of the neck and press the glass into the thread of the screw. When the glass
has hardened, the metal screw is turned by means of the cross handle, and
the bottle or other vessel withdrawn, leaving a moulded screw formed inside
the neck.
Having now described the nature of my said Invention, and how the same
is to be performed, I wish it to be understood that I do not confine myself to
the precise details herein-before described.
In witness whereof, I, the said Frederick Simpson, have hereunto set
my hand and seal, this Fourth day of September, One thousand eight
hundred and fifty-seven.
FREDERICK SIMPSON. (L.S.)
