IMPROVEMENTS IN POWER Looms
Year: 1849

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
STEEL, of Horton, in the Parish of Bradford, in the County of York, and
BENJAMIN EMMERSON, of the same Place, Overlookers, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Seventh day of June,
One thousand eight hundred and forty-nine, in the twelfth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the sai
James Steel and Benjamin Emmerson, our exors, admors, and assigns, Her
especial licence, full power, sole privilege and authority, that we, the said.
James Steel and Benjamin Emmerson, our exors, admors, and assigns, and
such others as we, the said James Steel and Benjamin Emmerson, our exors,
adors, or assigns, should at any time agree with, and no others, from time to
time and at all times during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, our Invention of "IMPROVEMENTS IN POWER
Looms;" in which said Letters Patent is contained a proviso, that we, the said
James Steel and Benjamin Emmerson, or one of us, should cause a particular

page_text: description of the nature of our said Invention, and in what manner the same
is to be performed, by an instrument in writing under our hands and seals, or
under the hand and seal of one of us, to be inrolled in Her said Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as, in and by the
same, reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
James Steel and Benjamin Emmerson, do hereby declare that the nature of
our said Invention, and in what manner the same is to be performed, are fully
described and ascertained in and by the following statement thereof, reference
being had to the Drawing hereunto annexed, and to the figures and letters
marked thereon, that is to say:-
Our Invention consists of modes of applying apparatus to relieve the swells,
in the shuttle boxes in looms, so that a shuttle when being picked from a
shuttle box will require less effort, and also so that when a shuttle is being
boxed it may pass into its box more easily than when it has to overcome the
pressure against the swell, and yet the ordinary stop rod will be free to act as
heretofore should the shuttle not be boxed.
And in order that our Invention may be most fully understood and readily
carried into effect, we will proceed to describe the means pursued by us.
DESCRIPTION OF THE DRAWING.
Figure 1 shows so much of an end view, and Figure 2 shows so much of a
plan of a power loom as will enable us to describe one arrangement of
apparatus for performing our Invention. a is the ordinary fly wheel, which
has a projection b fixed thereto, the fore end 6¹ of which projection is formed
into an incline; the back end thereof is formed with a projecting surface, so
that should the fly wheel turn in the wrong direction it will not act injuriously
on the apparatus, hereafter explained, but will simply lift one end of the lever
c, which is made to move on an axis for that purpose, as is shown by the
Drawing. The lever c moves on an axis c', and the end of the lever c rests
on one of the levers of the stop rod which press against the swells in the two
shuttle boxes, hence, when the fore end 6' of the projection b comes against
the lever c it moves that end outwards, and the other end of the lever c
moves the lever of the stop rod back, so that the shuttle may be picked
without the ordinary resistance of the stop rod; or the resistance of the stop
rod may be only modified or partially removed, according to the desire of the
parties using such loon, the lever c being arranged accordingly, so that the

page_text: projection 6 may act either to remove the pressure wholly or partially. h is a
bearer, on which the finger of the stop rod is supported after the projection
has passed the lever c, and until the shuttle is boxed; should the shuttle from
any cause not be boxed, then the stop rod will come into action in the ordinary
manner, for the projection 6 will have passed the lever c before the beat-up is
complete, and the stop rod finger will no longer be supported by the bearer h,
and thus will the swells be allowed to be pressed into the boxes by the
stop rod levers, so that should there be no shuttle in either of the boxes the
swells will be pressed inwards and not be stopped by the shuttle, and hence
will result the ordinary action of the stop rod. We would state that the
apparatus according to our Invention may be modified, and it is not absolutely
necessary that the fly wheel should be the cause of putting the apparatus into
motion; we do not therefore confine our Invention to the arrangement shown
at Figures 1 and 2, and we will describe some variations which may be
employed.
Figure 3 shews part of an end view, and Figure 4 part of a plan, of a loom
wherein the apparatus is put into action by means of a bar and incline fixed
to the end of a power loom. d is a fixed bar, having on it an incline e, and
the one end of the lever c is bent forward, as shown, and it carries a truck or
roller c', and the plate c which carries the axis of the truck or roller c³ can
move back, so as to give way should there be any rebound on the loom being
suddenly stopped, but the plate is prevented moving forwards by a stop c³ at
the end of the lever c, hence, when the beat-up has been completed and the
slay is going back the truck or roller will run up the incline and raise that
end of the lever c, and cause the other end, as in the former arrangement, to
move back the lever of the stop rod, by which the swells in the shuttle boxes
will be wholly or partially relieved from the pressure of the stop rod levers.
And although we prefer that the lever c should be separate from the stop rod,
yet it may be fixed to it, as shewn by Figure 5, c being a lever fixed to the
stop rod. The lever c carries a truck or roller in the manner above described,.
and the roller on the going back of the slay rises up an incline e, which,
causing the lever c to be raised, will also cause the levers of the stop rod to be
wholly or partially relieved from pressing on the swells of the shuttle boxes.
The bearer h in this as in the previous cases upholds the stop rod finger till
the shuttle is boxed.
Having thus described the nature of our Invention, and the manner of
performing the same, we would state that we do not confine ourselves to the
details herein shown and described, so long as the peculiar character of our

page_text: Invention be retained; but what we claim are, the means of arranging
apparatus for acting on the stop rod and swells of power looms, as herein
explained.
In witness whereof, we, the said James Steel and Benjamin Emmerson,
have hereunto set our hands and seals, this Third day of December, in
the year of our Lord One thousand eight hundred and forty-nine.
AND BE IT REMEMBERED, that on the Third day of December, in
the year of our Lord 1849, the aforesaid James Steel and Benjamin Emmerson
came before our said Lady the Queen in Her Chancery, and acknowledged
the Specification aforesaid, and all and every thing therein contained and
specified, in form above written. And also the Specification aforesaid was
stamped according to the tenor of the Statute made for that purpose..
