do hereby declare the nature of the said Invention for "IMPROVEMENTS"
IN PATTERN CHAINS OR OTHER SUCH APPARATUS USED IN WEAVING," to be as

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SQUIRE

greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of November, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Squire Diggle, Her special license that I, the said Squire Diggle,
my executors, administrators, and assigns, or such others as I, the said Squire
Diggle, 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
PATTERN CHAINS OR OTHER SUCH APPARATUS USED IN WEAVING," upon the
condition, amongst others, that I, the said Squire Diggle, by an instru-
ment 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 Squire Diggle, do hereby declare the
nature of my 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 and accompanying Drawing (that is to say):-
My Invention relates to the pattern chains or other such apparatus used
for shifting the position of the shuttles in what are commonly called " rising
box" looms, and also to other pattern chains or similar apparatus used in
fancy weaving for shedding the warp or other such purposes.
:
The construction I employ is shewn in face view at Fig. 1; Fig. 2 is a
longitudinal section, and Figs. 3 and 4 detached views of one of the links, such
links used here for illustration being of that form included in the Specification
of my Patent, dated October Fourteenth, One thousand eight hundred and
fifty-eight. The links a are formed with lugs b, so that when put together
they constitute hinged joints; through these lugs are passed bent wires or

page_text: split pins c, and the ends d thereof being then expanded the said pins are
confined in their position, and the links of the chain are held securely
together.
Having thus described and ascertained the nature of my said Invention,
5 and the manner in which the same is to be performed, I desire it to be under-
stood that I claim as secured to me under the above in part recited Letters
Patent, the use of the bent wires or split pins, for the purposes above
mentioned.

In witness whereof, I, the said Squire Diggle, have hereunto set my
hand and seal, this Twenty-fourth day of May, in the year of our
Lord One thousand eight hundred and fifty-nine.
SQUIRE DIGGLE. (L.S.)
