Year: 1857

page_text: LETTERS PATENT to Samuel Fox, of Deepcar, Sheffield, in the County of
York, Umbrella Manufacturer, for the Invention of "IMPROVEMENTS IN
FLY PRESSES."
Sealed the 18th December 1857, and dated the 20th June 1857.
PROVISIONAL SPECIFICATION left by the said Samuel Fox at the
Office of the Commissioners of Patents, with his Petition, on the 20th
June 1857..
I, SAMUEL Fox, of Deepcar, Sheffield, in the County of York, Umbrella
Manufacturer, do hereby declare the nature of the Invention for "IMPROVE-
MENTS IN FLY PRESSES," to be as follows:-
This Invention has for its object improvements .in fly presses, and consists
in arranging the stops, which regulate the distance within which the upper
dies approach the bed dies, in the following manner :-On, the standard of the
fly press, immediately above the main interior screw of the press, is a socket
with a screw thread cut in it, and there is a metal ring which screws into this
socket.. The screw of the press passes freely through this ring, but its descent
is arrested by an enlargement at the upper part of the screw stem coming in
contact with a flange on the top of the metal ring, and according as the metal
ring is more or less screwed into its socket, so will the descent of the screw of
the press be checked sooner or later, as may be required.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel. Fox in the Great Seal Patent Office on the
19th December 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL

thousand eight hundred and fifty-seven, in the twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Samuel Fox, Her special licence that I, the said Samuel Fox, my
executors, administrators, and assigns, or such others as I, the said Samuel
Fox, my 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 "IMPROVEMENTS IN FLY
PRESSES," upon the condition (amongst others) that I, the said Samuel
Fox, 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 Samuel Fox, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in fly presses, and consists
in arranging the stops, which regulate the distance within which the upper
dies approach the bed dies, in the following manner :-On the standard of the
fly press, immediately above the main interior screw of the press, is a socket
with a screw thread cut in it, and there is a metal ring which screws into this
socket. The screw of the press passes freely through this ring, but its descent
is arrested by an enlargement at the upper part of the screw stem coming in
contact with a flange on the top of the metal ring, and according as the metal
ring is more or less screwed into its socket, so will the descent of the screw of
the press be checked sooner or later, as may be required.

page_text: readily carried into effect, I will proceed to describe the Drawing hereunto
annexed.
DESCRIPTION OF THE DRAWING.
The Drawing shows a vertical section of so much of a fly press, arranged
according to my Invention, as is necessary to explain the way in which-my
improvements are applied.
a is the standard of the press, and 6 is a socket fixed to it immediately above
the main interior screw of the press; c is a metal ring which screws into the
socket b, to a greater or less extent, according as it is desired that the descent
of the screw stem d shall be sooner or arrested by the enlargement e, on
the stem coming in contact with the stop c; f is a set screw which locks the
stop c by pressing against it the piece g, which lays loosely in a recess in the
socket b.
In witness whereof, I, the said Samuel Fox, have hereunto set my
hand and seal, this Seventeenth day of December, in the year of our
Lord One thousand eight hundred and fifty-seven.
Witness,
GEORGE WOOD, of Deepcar.
