IM- PROVEMENTS IN SHUTTLES EMPLOYED IN LOOMS FOR WEAVING
Year: 1874

page_text: LETTERS PATENT to John Smith, of Cowling, near Bradford, in the
County of York, Commission Weaver, for the Invention of "IM-
PROVEMENTS IN SHUTTLES EMPLOYED IN LOOMS FOR WEAVING."
Sealed the 4th June 1875, and dated the 5th December 1874.
PROVISIONAL SPECIFICATION left by the said John Smith at the
Office of the Commissioners of Patents, with his Petition, on the
5th December 1874.
I, JOHN SMITH, of Cowling, near Bradford, in the County of York,
Commission Weaver, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN SHUTTLES EMPLOYED IN LOOMS FOR WEAVING," to be as
follows:-
This Invention relates to the pin for holding the bobbin or spool
within the shuttle, and my improvements consist in the employment of
a short pin extending to about the middle of the bobbin when placed
thereon, and over this pin is a spring rather longer than the bobbin or
spool. This spring is fixed to the pin at the point where the latter is
fastened into the shuttle, and at the other end of the said spring is a
catch, so that when the bobbin is placed over the spring and pin the

page_text: "catch" prevents it from being drawn therefrom until the spring is
depressed by the operator. By this arrangement moveable pins are dis-
pensed with, thus allowing shuttles to be made stronger, and the bobbin
or "spool" is held firmly on the piu with very little pressure, and there-
fore do not wear out or get broken so frequently.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Smith in the Great Seal Patent Office
on the 5th June 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SMITH, of Cowley, near Bradford, the County of York, Commission
Weaver, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of December, 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 suc-
cessors, give and grant unto me, the said John Smith, Her special
licence that I, the said John Smith, my executors, administrators,
and assigns, or such others as I, the said John Smith, 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 "IMPROVE-
MENTS IN SHUTTLES EMPLOYED IN LOOMS FOR WEAVING," upon the condition
(amongst others) that I, the said John Smith, 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 John Smith, do hereby declare
the nature of my said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the
following statement, that is to say :-
-
This Invention relates to the pin for holding the bobbin or spool
within the shuttle, and my improvements consist in the employment of
a short pin extending to about the middle of the bobbin when placed
thereon, and over this pin is a spring rather longer than the bobbin or
spool. This spring is fixed to the pin at the point where the latter is
fastened into the shuttle, and at the other end of the said spring is a
catch, so that when the bobbin is placed over the spring and pin the
"catch" prevents it from being drawn therefrom until the spring is
depressed by the operator. By this arrangement movable pins are dis-
pensed with, thus allowing shuttles to be made stronger, and the bobbin
or "spool" is held firmly on the pin with very little pressure, and there-
fore do not wear out or get broken so frequently.
In order that this Invention may be more clearly understood I herein
give reference to the accompanying Sheets of Drawings, marked with
figures and letters of reference.
.
Fig. 1 is a side elevation of shuttle partly in section, A. is the short
pin over which is the spring B with the catch C on the end thereof.
This spring B is sufficiently pliable to allow of the bobbin being placed
thereon without the necessity of the pin being hinged as usual, the
short pin being sufficiently long to keep the bobbin steady, and the
catch preventing the bobbin from being drawn off until the spring is
depressed by the operator placing his thumb or finger on the end, when
the bobbin can be easily taken off.
Fig. 2 is detail of pin of similar construction, the spring D being
for the purpose of preventing too much strain on the spring B at the
centre thereof.

page_text: I claim the construction and employment of shuttle pins, substantially
as herein shewn and described.
In witness whereof, I, the said John Smith, have hereunto set
my hand and seal, this Thirty-first day of May, in the year of
Lord One thousand eight hundred and seventy-five.
Witness,
J. W. TASKER,
Patent Agent,
