Year: 1867

page_text: LETTERS PATENT to William Bullough, of Blackburn, in the County of
Lancaster, Engineer, for the Invention of "IMPROVEMENTS IN LOOMS:
FOR WEAVING."
Sealed the 24th December 1867, and dated the 27th June 1867.
PROVISIONAL SPECIFICATION left by the said William Bullough at the
Office of the Commissioners of Patents, with his Petition, on the
27th June 1867.
I, WILLIAM BULLOUGH, of Blackburn, in the County of Lancaster, Engineer,.
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
LOOMS FOR WEAVING," to be as follows:-
This Invention has for its object, firstly, the construction and appli-
cation of mechanism to looms for weaving, and to the shuttles of such looms,.
whereby the motion of the loom is arrested when from any cause the weft.
thread is broken. The tension or drag of the weft thread in its passage
from the shuttle acts on a staple or lever attached to the shuttle, counter-
balanced by a spring or by gravitation; when from any cause the weft thread
breaks the staple or lever above referred to is liberated and comes in
contact with a projecting finger or lever fixed to the lay or slay, which
actuates another lever attached to the side frame of the loom, whereby a
lever and catch is liberated, the catch falling into a notch or against a tooth
in a wheel fixed to the crank shaft, thus stopping the loom.

vention of "floats" and breakage of warp threads. Attached to a traversing
frame worked by an excentric between the healds and the reed are a number
of points or dents intersecting the warp threads. When the shed is partially
opened the traverse frame carrying the points or dents moves in the direction
of the reed, but returns before the arrival of the lay, should any obstruction
prevent the free separation of yarn in the formation of the shed for the
shuttle to traverse the points or dents above referred to are retarded, and
levers connected there with act on the stop rod handle and stop the loom,
thus preventing loss of time and inferior work.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Bullough in the Great Seal Patent Office on the
27th December 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BULLOUGH, of Blackburn, in the County of Lancaster, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of June, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
réign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Bullough, Her special licence that I, the said Williamı
Bullough, my executors, administrators, and assigns, or such others as I,
the said William Bullough, 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 LOOMS FOR WEAVING," upon the condition (amongst others), that I,
the said William Bullough, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-,
ticularly 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 William Bullough, 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:
This Invention has for its object, firstly; the construction and appli-">
cation of mechanism to loons for weaving, and to the shuttles of such looms,..
whereby the motion of the loom is arrested when from any cause the weft
thread is broken. The tension or drag of the weft thread in its passage from
the shuttle acts on a staple or lever attached to the shuttle, counterbalanced..
by a spring or by gravitation; when from any cause the weft thread breaks
the staple or lever above referred to is liberated and comes in contact with
a projecting finger or lever fixed to the lay or slay, which actuates another
lever attached to the side frame of the loom, whereby a lever and catch is
liberated, the catch falling into a notch or against a tooth in a wheel fixed to
the crank shaft, thus stopping the loom.
Secondly, in the construction and application of mechanism for the pre-
vention of "floats" and breakage of warp threads. Attached to a traversing
frame worked by an eccentric between the healds and the reed are a
number of points or dents intersecting the warp threads, when the shed is
partially opened the traverse frame carrying the points or dents moves in the
direction of the reed, but returns before the arrival of the slay.
obstruction prevent the free separation of yarn in the formation of the shed
for the shuttle to traverse the points or dents above referred to are retarded,
and levers connected therewith act on the stop rod handle and stop the loom,
thus preventing loss of time and inferior work.
Should any
Such being the nature and object of this my said Invention I will now
proceed to describe the same fully; and in order that the same may be
distinctly understood I have hereunto annexed two Sheets of Drawings, and
have marked the same with figures and letters of reference, the same letter
referring to the same part in the various views or figures.
Fig. 1 is side elevation of shuttle; Fig. 2 is a plan view of the same;
Fig. 3 is shewn modification of shuttle shewn at Fig. 2; Fig. 4 is view of
parts of slay; Figs. 5 and 6 are details; Fig. 7 shews part of loom.
At A is shewn the staple or lever attached to the shuttle at a and counter-
balanced by the spiral spring B; when from any cause the weft thread C
breaks the staple or lever A is liberated, and projecting from the shuttle
comes in contact with the finger D fixed on the end of the spindle E (which
spindle is supported and works in the casting fixed to the slay) moving the
lever D, and by means of the rod D² actuating the lever D³, the projection
d thereon liberates the lever D', whereon the connecting rod E draws down
the catch F into the teeth of the wheel G (which wheel is fixed on the crank

page_text: shaft G¹) when the catch F comes in contact with the teeth; the spring
lever H to which the catch is attached is moved by the direction of the slay,
causing the end of the lever J attached thereto by the stud K to be impelled
against the stop handle L, drawing, the lever and break N to the periphery
of the fly wheel and stopping the loom. On the lever D is shewn an
incline P which by means of the pin p attached to the lever L depresses
the said lever, allowing the weighted end g of the catch lever F to raise the
said catch clear of the teeth ready for re-starting the loom.
At Figs. 8 and 9 is shewn view of the points or dents R on the shaft S,
which shaft extends from slay sword to slay sword, and moves therewith; when
the shed is partially opened the traverse frame carrying the dents R move
in the direction of the reed R¹, should any obstruction prevent the free
passage of the said points or dents, as shewn at R2, the lever V connected
therewith acts on the projection W on the stud W', moving the lever X
against the stop handle L, and stops the loom.
Having thus fully described the nature and particulars of this my said
Invention, together with the manner in which the same is to be or may be
performed or carried into practical effect, I would remark in conclusion that
I claim,―
Firstly, the mechanism attached to the shuttle, as herein-before described.
Secondly, the mechanism attached to the shuttle arranged and combined
with the levers for effecting the stoppage of the loom, as herein-before
described.
Lastly, the combined arrangement of the dents or points and levers for
purposes herein-before mentioned, as shewn in the Drawings and fully
described.
In witness whereof, I, the said William Bullough, have hereunto set
my hand and seal, this Twenty-third day of December, One thousand
eight hundred and sixty-seven.
