CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1874

page_text: LETTERS PATENT to Nicholas Edge, of Moston, near Manchester, in
the County of Lancaster, Engraver, and William Trevor, of Newton
Heath, near Manchester aforesaid, Manufacturer, for the Invention
Sealed the 17th July 1874, and dated the 20th May 1874.
PROVISIONAL SPECIFICATION left by the said Nicholas Edge and
William Trevor at the Office of the Commissioners of Patents, with
their Petition, on the 20th May 1874.
We, NICHOLAS EDGE, of Moston, near Manchester, in the County of
Lancaster, Engraver, and WILLIAM TREVOR, of Newton Heath, near
Manchester aforesaid, Manufacturer, do hereby declare the nature of
the said Invention for "CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING," to
be as follows:-
The object of our improved system of taking up is to procure absolute
the nines of

page_text: cloth to the other without any alteration of pinions, springs, or weights,
or without any interference whatever with the motion after it has been
adjusted at the outset of the piece, the motion accomodating itself to
the increasing size of the cloth roller with accuracy.
The means by which this great desideratum is accomplished consists
of a combination of the motion known as the sun and planet motion
with the positive or any other taking-up motion. The former motion is
made to act so as imperceptibly to diminish the speed of the positive, or
whatever other motion it may be combined with precisely in proportion
as the cloth beam gains in circumference.
When our Invention is applied to a loom with the ordinary positive
taking-up motion we drive the train of wheels and pinions connected to
the cloth beam by a pall actuated by the lay sword, and this pall takes
into a ratchet wheel. The position of the pall is varied as the cloth
beam increases in diameter by a lever bearing on the cloth as usual.
The sun and planet motion is applied to the axle of any of the wheels
or pinions between the axle of the ratchet wheel and that of the cloth
beam, and the sun and planet motion governs the take-up as above
described.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Nicholas Edge and William Trevor in the Great
Seal Patent Office on the 23rd October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, NICHOLAS
EDGE, of Moston, near Manchester, in the County of Lancaster, Engraver,
and WILLIAM TREVOR, of Newton Heath, near Manchester aforesaid, 2
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of May, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and a
successors, give and grant unto us, the said Nicholas Edge and

page_text: William Trevor, Her special licence that we, the said Nicholas Edge
and William Trevor, our executors, administrators, and assigns, or such
others as we, the said Nicholas Edge and William Trevor, 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 "CERTAIN IMPROVEMENTS IN
LOOMS FOR WEAVING," upon the condition (amongst others) that we, the
said Nicholas Edge and William Trevor, our executors or administrators,
by an instrument in writing under our, or their, or one of our or 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 we, the said Nicholas Edge and William
Trevor, do hereby declare the nature of our 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) :—
The object of our improved system of taking up is to procure absolute
regularity and evenness as regards quality from one end of the piece of
cloth to the other without any alteration of pinions, springs, or weights,
or without any interference whatever with the motion after it has been
adjusted at the outset of the piece, the motion accomodating itself to
the increasing size of the cloth beam with accuracy.
The means by which this great desideratum is accomplished consists
of a combination of the motion known as the sun and planet motion
with the positive or any other taking-up motion. The former motion is
made to act so as imperceptibly to diminish the speed of the positive or
whatever other motion it may be combined with precisely in proportion
as the cloth beam gains in circumference.
When our Invention is applied to a loom with the ordinary positive
taking-up motion, we drive the train of wheels and pinions connected to
the cloth beam by a pall actuated by the lay sword, and this pall takes
into a ratchet wheel. The position of the pall is varied as the cloth
beam increases in diameter by a lever bearing on the cloth as usual.

page_text: or pinions between the axle of the ratchet wheel and that of the cloth
beam, and the sun and planet motion governs the take-up as above
described.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying
Sheet of Drawings, in which Fig. 1 is a side elevation and Fig. 2 a front
elevation of part of a loom to which our improvements are applied.
A is the loom side; B, the lay swords; and C is a bracket bolted to
one of the lay swords; this bracket is connected by the link D to the
oscillating frame E, which is jointed to a stud attached to the loom side.
In the frame E is the slot Z, in which is a stud connected by the link F
to one end of the lever G, the other end resting on the cloth beam Y.
The small iron roller H. rests on the lever G to press it on the cloth beam,
and the ends of this roller H are guided in slots as usual. The lever G
is jointed to the fulcrum stud X, which projects from the link W sus-
pended from the breast beam. The stud in the slot Z is connected by
the link I to the setting up lever J, to which is jointed the pall K
working in the ratchet wheel L, which is keyed on the shaft M. The
setting up lever J is loose on this same shaft, and to it is fixed the
pinion N, which by means of the train of wheels and pinions shewn in
the Drawings gives motion to the centre wheel O of the sun and planet
motion. The wheel O is loose on the shaft P. The bevel pinion O' in
the wheel O gears into the two wheels O' and O³%; the former is fast to
the spur wheel O*, and the latter is connected to the pinion R gearing
into the wheel 8 fixed to the axle of the cloth beam Y. Q is a ratchet
wheel worked by a catch from the lay sword forming part of the ordinary
taking-up motion. As the cloth accumulates on the beam Y the outer
end of the lever G is raised and the inner end is lowered, thereby
lowering the stud by which the links F and I are united in the slot Z of
the frame E, and reducing the motion of the cloth beam in proportion
to the increasing diameter of the cloth wound upon it.
Having thus stated the nature of our Invention, and described a
convenient manner of performing the same, we wish it to be understood
that we do not intend to limit ourselves to the details given, as the same
may be varied or modified, and we declare that we claim the application
of the system of wheels known as the sun and planet motion in combina-

page_text: tion with any ordinary taking-up motion to impart the requisite motion
to the cloth beam.
In witness whereof, we, the said Nicholas Edge and William Trevor,
have hereto set our hands and seals, this Twenty-second day
of October One thousand eight hundred and seventy-four.
