Sealed the 15th December 1874, and dated the 20th June 1874.
PROVISIONAL SPECIFICATION left by the said James Lang, Thomas
Westly, and Walter Bibby at the Office of the Commissioners of
Patents, with their Petition, on the 20th June 1874.
•
We, JAMES LANG, of Preston, in the County of Lancaster, Over-1
looker, THOMAS WESTLY, and WALTER BIBBY, of the same Place,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE WEAVING SHUTTLE," to be as follows:-
Our Invention consists of a simple and efficient apparatus, which we
fix to the cyc end of the weaving shuttle to prevent flotes in weaving
any kind of material. To the eye end of the shuttle we fix a small
bracket, in which we fix a small lever rounded at each end; in this

page_text: same bracket we place a slide bar. We use a small piston, through
which we pass the yarn, and two small springs, one to act on the said'
piston and the other to act upon the slide bar. The yarn from the cop
passes freely from the cop through a small hole provided in the bracket,
past the lever, slide bar, and through hole in piston, and out of the
éye in the shuttle end; but when a flote occurs the yarn presses against
the lever, and by means of the springs moves slide bar and piston,
breaks cop thread, and stops the loom.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Lang, Thomas Westly, and Walter Bibby,
in the Great Seal Patent Office on the 18th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
LANG, of Preston, in the County of Lancaster, Overlooker, THOMAS
WESTLY, and WALTER BIBBY, both of the same Place, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of June, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said James Lang, Thomas Westly and
Walter Bibby, Her special licence, that we, the said James Lang,
Thomas Westly, and Walter Bibby, our executors, administrators, and
assigns, or such others as we, the said James Lang, Thomas Westly,
and Walter Bibby, our 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 WEAVING SHUTTLE," upon the
condition (amongst others) that we, the said James Lang, Thomas
Westly, and Walter, our executors or administrators, by an in-
instrument in writing under our, 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 Scal Patent Office within six

page_text: its spring pressure the lever, downward, which coming down sharply on
to the thread with a snap action, it has the effect of breaking it (outside
of the shuttle), thereby saving the weaver the trouble every time a break
occurs of rethreading the shuttle.
Having described our Invention fully, we wish it to be distinctly
understood that we do not confine ourselves to the precise details we
have described, as we may and shall doubtless alter such details without
departing from the principle of this our Invention, but what we claim as
secured to us herein is,-
First. The bracket d, piston lever e, and spring h, substantially as and
for the purposes herein-before set forth.
Second. The general arrangements of the several parts, or any merc
modefication of the same, substantially as and for the purposes herein-
before set forth.
In witness whereof, wc, the said James Lang, Thomas Westly, and
Walter Bibby, have hereunto set our hand and seals, this
Tenth day of December, in the year of our Lord One thousand
eight hundred and seventy-four.
Witness,
JOHN LEWIS,
Engineer & Patent Agent,
Preston,
Lancashire.
