CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1862

page_text: LETTERS PATENT to John Benyon, of Swinton, near, the City of Man-
chester, Manager, for the Invention of "CERTAIN IMPROVEMENTS IN LOOMS
FOR WEAVING."
Sealed the 16th January 1863, and dated the 30th July 1862.
PROVISIONAL SPECIFICATION left by the said John Benyon at the Office
of the Commissioners of. Patents, with his Petition, on the 30th July
1862.
I, JOHN BENYON, of 'Swinton, near the City of Manchester, Manager, do
hereby declare the nature of the said Invention for "CERTAIN IMPROVEMENTS
IN LOOMS FOR WEAVING," to be as follows:-
My Invention relates to the taking-up motion, and it consists in an
improved arrangement of parts for giving a positive take-up motion to the
roller on which the fabric is wound as it is delivered by the loom. To the
under side of the take-up roller is applied a rod in the usual manner, which
rod, as the fabric accumulates on the roller, moves a lever to which a chain
is connected; this chain is also connected to a lever hinged to the lay sword,
and passing through the catch lever by which the ratchet wheel and a train
of wheels and pinions are put in motion. On commencing a piece, and when
the take-up roller is bare, the catch lever vibrates to the greatest extent, but
as the fabric accumulates on the take-up roller, the vibration of the catch

page_text: lever is proportionately reduced to diminish the motion of the take-up roller.
The lever hinged to the lay sword is hinged in such a manner that the
fulcrum can be brought nearer to or removed from the fulcrum of the swing
shaft, thus affording facility in regulating the take-up motion to the quality
of the fabric. A similar arrangement of parts may be applied to the warp
beam to effect a positive let-off motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Benyon in the Great Seal Patent Office on the 29th
January 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BENYON, of Swinton, near the City of Manchester, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of July, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Benyon, Her special license that I, the said John Benyon, my
executors, administrators, and assigns, or such others as I, the said John
Benyon, 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 "CERTAIN IMPROVEMENTS
IN LOOMS FOR WEAVING," upon the condition (amongst others) that I, the
said John Benyon, 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 bo 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 Benyon, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement,
that is to say:-
'
My Invention relates to the taking-up motion, and it consists in an
improved arrangement of parts for giving a positive take-up motion to the
Toller on which the fabric is wound as it is delivered by the loom. . My

page_text: improved arrangement of parts may be applied to the warp beam to effect a
positive let-off motion.
And in order that my Invention may be fully understood and readily
carried into effect, I will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Figure 1 represents part of a loom to which my improvements are applied
to the taking-up motion; Figure 2 is a front view of the same.
, a is the
crank shaft; b, the lay or batten; c, the lay sword; d, the breast beam; e, the
taking-up roller; f, the pressing rod; 9 is the ratchet wheel driven by
the catches / hinged to the lever i. The ratchet wheel communicates motion
in the usual manner to the taking-up roller e by the train of wheels and
pinions, clearly shewn in the Drawing.
My Invention, which consists in gradually diminishing the amount of motion
given to the taking-up roller e in proportion to the increasing diameter of the
cloth or fabric wound upon it, is performed in the following manner :-Tho
pressing rod is supported in the levers j, only one of which is shewn in the
Drawing; these lovers vibrate on studs k, and to one lever is cast or fixed a
short lever ', to which is attached the end of the chain or cord 7 passing above
over the guide pulley m, and attached below to the end of the link n, the other
end of which is jointed to a stud o, which is adjustable in the bracket P fixed
to the lay sword c. To the link n is fixed a stud taking into a slot in
the catch lever i. When the taking-up roller or cloth beam e is empty,
the pressing rod f, being in contact with it, causes the levers j and j' to lower
the chain or cord 7, and with it the end of the link n, thus bringing the stud
in the link n towards the centre of the ratchet wheel g, consequently when
the loom is at work the lay sword imparts the greatest vibration to the catch
lever i, and the catches h communicate this motion to the cloth beam e; but
as the cloth accumulates on the cloth beam, the pressing rod f actuating the
levers and gradually raise the chain or band l, and with it the end of the
link 7, thus increasing the distance of the stud in the link n from the fulcrum
of the ratchet wheel g, and reducing the vibration of the lever i and the
amount of motion imparted to the ratchet wheel and to the cloth beam.
When my improved arrangement of parts is applied to the let-off motion the
action is reversed, that is to say, the pressing bar bearing on the warp beam
will gradually approach the centre of the beam during the working of the
loom, consequently the gradual diminution in the diameter of the warp beam
is made by levers and link and chain to produce a proportionately increasing
motion in the warp beam.
Having thus stated the nature of my Invention, and described the manner

page_text: of performing the same, I declare that I claim the novel combination of the
parts marked f, j, k, j', l, m, and n, together with those by which they are
actuated, and to which they impart motion for the purpose of effecting either
a positive take-up motion or a positive let-off motion.
In witness whereof, I, the said John Benyon, have hereunto. set my
hand and seal this Twenty-seventh day of January, in the year of
our Lord One thousand eight hundred and sixty-three..
JOHN BENYON. (L.S.)
