IMPROVEMENTS IN THE CONSTRUCTION OF SPRINGS
Year: 1852

page_text: LETTERS PATENT to James Webster, of Leicester, in the County
of Leicester, Engineer, for the Invention of "IMPROVEMENTS IN
THE CONSTRUCTION OF SPRINGS."
Sealed the 12th January 1853, and dated the 14th October 1852.
PROVISIONAL SPECIFICATION left by the said James Webster
at the Office of the Commissioners of Patents, with his Petition,
on the 14th October 1852.
I, JAMES WEBSTER, of Leicester, in the County of Leicester,
Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF SPRINGS" to be as follows:-
This Invention consists of constructing springs by bending bars or
plates of steel to and fro so as to form angles or bends in opposite
directions, leaving a space between each bend of a width depending on
the play the parts of the spring shall have before they come together,
and no longer admit further compression.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Janes Webster in the Great Seal Patent Office,
on the 14th April 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JAMES WEBSTER, of Leicester, in the County of Leicester, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of October, in the year
of our Lord One thousand eight hundred and fifty-two, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said James Webster, Her special licence that I, the
said James Webster, my executors, administrators, and assigns, or such
others as I, the said James Webster, 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 THE CONSTRUC-
TION OF SPRINGS," upon the condition (amongst others) that I, the said
James Webster, by an instrument in writing under my hand and seal,
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 imaniediately after the date of the said Letters
Patent.
:
NOW KNOW YE, that I, the said James Webster, 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):
My Invention consists of constructing springs by bending bars or
plates of steel to and fro so as to form angles, or bends in opposite
directions, leaving a space between each bend of a width depending on
the play the parts of the spring shall have before they come together,
and no longer admit further compression. And in order that my

page_text: Invention may be most fully understood, and readily carried into effect,
I will proceed to describe the means pursued by me. I prefer to em-
ploy flat bars or plates of steel, with parallel sides and edges, but other
sections of steel bars or plates may be used.
DESCRIPTION OF THE DRAWING.
Figure 1, shows a side view, and Figure 2, an end view of a spring
constructed according to my Invention, which is suitable to be used for
the supporting of a carriage body or other purposes; and the same will
be made of a strength and size according to the weight or pressure to
which it is to be subjected, as is well understood in the making of other
forms of springs; and each spring will consist of more or less bends, and
have more or less space left between the bends, according as it is
desired to give more or less action to a spring; a spring having been
made by bending a bar or plate of steel into the form desired, it is to
be tempered, as is well understood.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that although the
section of steel bar or plate may be varied, and although the angle of
the bends may be varied, what I claim is, the constructing of springs
by bending bars or plates of steel to and fro so as to form angles or
bends in opposite directions, leaving a space between each bend of. a
width depending on the play the parts of a spring shall have before
they come together, and no longer admit further compression, as herein
explained.
In witness whereof, I, the said James Webster, have hereunto
hand and seal, this Twenty-ninth day of March, in the
year of our Lord One thousand eight hundred and fifty-three.
my
Witness,
SAMUEL PERKINS.
JAMES WEBSTER. (L.S.)
