James Sutcliffe Smith, and William Chew at the Office of the Com-
missioners of Patents, with their Petition, on the 12th November
1874.
We, JAMES SMITH SUTCLIFFE, JAMES SUTCLIFFE SMITH, and WILLIAM
CHEW, all of Bacup, in the County of Lancaster, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN Looms FOR WEAVING,"
to be as follows:-
:
The object of this Invention is to prevent the formation of "floats":
and to stop the movement of the loom whenever owing to the breakage
of the warp threads, or from other causes, the shuttle diverges from its
proper course in passing from one shuttle box to the other.

In place of the fixed "nogs" or shuttle guides usually employed in
front of the entrance to each shuttle box, or in front of such "nogs,"
we employ movable "nogs or other projections of boxwood or other
suitable material, which said " nogs or
other projections are connected
by means of a rod or otherwise to the ordinary or other stopping motion
of the loom in such a manner that when the shuttle diverges from its
"
nogs
proper course and strikes against one of the said movable "
other projections it displaces the same, and by its connection with the
stop motion causes the loom to be instantly stopped.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Smith Sutcliffe, James Sutcliffe Smith, and
William Chew in the Great Seal Patent Office on the 12th May
1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
SMITH SUTCLIFFE, JAMES SUTCLIFFE SMITH, and WILLIAM CHEW, all of
Bacup, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of November, 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 us, the said James Smith Sutcliffe, James
Sutcliffe Smith, and William Chew, Her special licence that we, the said
James Smith Sutcliffe, James Sutcliffe Smith, and William Chew, our
executors, administrators, and assigns, or such others as we, the said
James Smith Sutcliffe, James Sutcliffe Smith, and William Chew, 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 LOOMS FOR WEAVING," upon the condition (amongst others) that we, the
said James Smith Sutcliffe, James Sutcliffe Smith, and William Chew,

page_text: our executors or administrators, by an instrument in writing under our,
or one of 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 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 James Sutcliffe Smith (on behalf
of myself and the said James Smith Sutcliffe & William Chew), 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 and accompanying Drawings (that is
to say):―
The object of this Invention is to prevent the formation of "floats"
and to stop the movement of the loom whenever owing to the breakage
of the warp threads or from other causes the shuttle diverges from its
proper course in passing from one shuttle box to the other.
""
In place of the fixed "nogs" or shuttle guides usually employed in
front of the entrance to each shuttle box, or in front of such " nogs," we
employ movable nogs or other projections of boxwood or other suitable
material, which said " nogs" or other projections are connected by means
of a rod or otherwise to the ordinary or other stopping motion of the loom
in such a manner that when the shuttle diverges from its proper course
and strikes against one of the said movable " nogs or other projections it
displaces the same, and by its connection with the stop motion causes
the loom to be instantly stopped.
"
In wide looms an additional "nog," or "nogs," or other projections
may also be placed at suitable distances between the shuttle boxes.
Such being the nature and object of our said Invention we will now
proceed to describe more in detail the manner in which the same is to be
or may be performed or carried into practical effect, and in order that
the same may be clearly understood, I have annexed hereunto a Sheet of
Drawings illustrative thereof, and have marked the same with figures
and letters of reference corresponding with those in the following
explanation thereof:-
Fig. 1 in the annexed Drawing is a front elevation, Fig. 2 an end view
(partly in section), and Fig. 3 a plan view of so much of a power loom
as is necessary to illustrate the application of our improvements thereto.

page_text: a, a, is the framing of the loom; b, b, the cloth beam; c, c, the lathe
or slay; and d, d, the shuttle boxes; and e, e, the crank shaft; ƒ,ƒ, arẹ
the movable nogs which are mounted so as to be capable of oscillating
on pins or studs 9, 9, and are connected together by a rod h, h, so that
if the shuttle should strike either of them it causes them both to oscillate;
the right-hand nog acts against a bracket i, i, and whenever the shuttle
flies out of its proper course in the "shed" and strikes against either of
the nogs this bracket is pushed in front of a finger k, k, fixed on the
rod, 1, which carries the ordinary weft fork m, m, (see dotted lines in
Fig. 3), and as the slay c, c, beats up the bracket i, i, comes in contact
with this finger k, k, and causes the knocking-off lever n, n, to force the
spring handle o, o, out of its notch, and by moving the driving strap
from the fast to the loose pulley stop the loom.
Fig. 4 shows a modification wherein the right-hand nog and the
bracket are made in one piece.
Having now described the nature and object of our said Invention,
together with the manner in which the same is to be or may be per-
formed or carried into practical effect, we wish it to be understood that
we claim as our Invention, the application to looms for weaving of
movable nogs, guides, or projections, so connected to the stop motion of
the loom that upon the shuttle striking against either of the nogs or
projections and displacing it the movement of the nog releases the spring
handle from its notch and thus stops the loom.
In witness whereof, I, the said James Sutcliffe Smith (on behalf
of myself and the said James Smith Sutcliffe and William Chew),
have hereunto set my hand and seal, this Eleventh day of May,
in the year of our Lord One thousand eight hundred and seventy-
