page_text: LETTERS PATENT to George Horrocks, of Pilkington, in the County of
Lancaster, Shuttle Maker. for the Invention of "CERTAIN IMPROVEMENTS
IN SHUTTLES."
Sealed the 16th November 1855, and dated the 24th May 1855.
PROVISIONAL SPECIFICATION left by the said George Horrocks at the
Office of the Commissioners of Patents, with his Petition, on the 24th
May 1855.
I, GEORGE HORROCKS, of Pilkington, in the County of Lancaster, Shuttle
Maker, do hereby declare the nature of my said Invention for "CERTAIN
IMPROVEMENTS IN SHUTTLES" to be as follows:-
My Invention consists in furnishing the shuttle with a back plate and
spring, which shall act against the tail of the "skewer" in such a manner, that
upon the skewer being raised to the perpendicular, in order to put the "cop"
on, it shall be held firmly in that position, and, upon its being replaced within
the shuttle in a horizontal position, it shall also be simply retained there.

by the said George Horrocks in the Great Seal Patent Office on the
24th November 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HORROCKS, of Pilkington, in the County of Lancaster, Shuttle Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of May, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said George Horrocks, Her especial license that I, the said George
Horrocks, my executors, administrators, and assigns, or such others as I, the
said George Horrocks, 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 "CERTAIN IMPROVE-
MENTS IN SHUTTLES," upon the condition (amongst others) that I, the said
George Horrocks, 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
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Horrocks, 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 and accompanying Drawing (that is to say):-
This Invention consists in furnishing the shuttle with a spring of peculiar
construction, which shall act against the tail of the "skewer" in such a
manner, that upon the "skewer" being raised to the perpendicular, in order
to put the "cop" on, it shall be held firmly in that position, and, upon its
being replaced within the shuttle in a horizontal position, it shall also be
similarly retained there.
In order that this Invention may be the better understood and explained in
detail, I have hereunto attached a Sheet of Drawing, made about real size,
and having on both Figs. similar letters of reference on corresponding parts of
the shuttles. Fig. 1 represents a longitudinal section of a shuttle, and illus-
trates the spring of peculiar formation, the spring being elbowed, and its one

page_text: half forming a back plate, which is secured to the bottom of the shuttle.
Fig. 2 exhibits a longitudinal section of a shuttle, illustrative of a modified
application of the peculiar spring, which modification I prefer for its greater
certainty of action and durability. a, a, represents the body of the shuttle,
and the skewer; c is the tail of the skewer, simply moving on a pivot d,
and e is the spring. In Fig. 1 the dotted lines represent the skewer in a
perpendicular position, illustrative of its action on the spring. In Fig. 2 the
dotted lines exhibit the skewer half raised, and also illustrate its effect upon
the spring, in both of which arrangements the ordinary "cotter wires" are
entirely dispensed with.
Having now described the nature of this Invention, and the manner in
which the same may be performed, I wish it to be distinctly understood that
I claim the application, employment, and use of the peculiarly formed springs,
exhibited at Figs. 1 and 2 in the Drawing annexed, with the corresponding or
appropriate tail-piece, to the "skewer" of shuttles), or any slight modification
of the saine, for the purpose of maintaining the "skewer" firmly in either a
vertical or horizontal position, as herein particularly described and set forth.
In witness whereof, I, the said George Horrocks, have hereunto set
my hand and seal, this Twenty-third day of November, in the year
of our Lord One thousand eight hundred and fifty-five.
