Year: 1874

page_text: LETTERS PATENT to James Greenwood, of Bradford, in the County)
of York, and Sam Balme, of Halifax, in the aforesaid County of
York for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING ”
Scaled the 12th January 1875, and dated the 15th July 1874.
PROVISIONAL SPECIFICATION left by the said James Greenwood and
Sam Balme at the Office of the Commissioners of Patents, with,
their Petiton, on the 15th July 1874.
We, JAMES GREENWOOD, of Bradford, in the County of York, and
SAM BALME, of Halifax, in the aforesaid County of York, 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 the more effectual and uniform
letting off of the warp from the warp beam, and the improvements
consist in conveying the warp direct from the warp beam through one
or more pairs of fluted, grooved, covered, or plain rollers, which rollers.
gradually draw the warp from the warp beam, and feed it forward to

page_text: the healds or harness as it is required for the purpose of weaving, and in
such uniform quantity that we are enabled to weave a uniform cloth
from one end of the warp to the other. These rollers are connected to
and driven by a train of gearing from the picking shaft or crank shaft
of the loom, which may or may not be assisted by pullies and strap or
pegged pullies and chains. A clutch box or its equivalent is employed
for throwing the wheels in and out of gear when the weaver desires to
turn back the warp. By these means we dispense with the usual heavy
weights and levers, ropes and friction pullies, and are enabled to produce
an evenly woven piece throughout.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Greenwood and Sam Balme in the Great
Seal Patent Office on the 14th January 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES

year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said James Greenwood and Sam Balme, Her
special license that we, the said James Greenwood and Sam Balme,
our executors, administrators, and assigns, or such others as we, the said
James Greenwood and Sam Balme, 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 of "IMPROVEMENTS IN LOOMS FOR WEAVING," upon the
condition (amongst others) that we, the said James Greenwood and Sam
Balme, 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

page_text: 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 James Greenwod and Sam
Balme, 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) :-
This Invention has for its object the more effectual and uniform
letting off of the warp from the warp beam, and the improvements
consist in conveying the warp direct from the warp beam through onc
or more pair of fluted, grooved, or plain rollers, which rollers gradually
draw the warp from the beam, and feeds it forward to the healds or
harness as it is required for the purpose of weaving, and in such uniform
quantity that we are enabled to weave a uniform cloth from one end of
the warp to the other. These rollers are connected to and driven by a
train of gearing from the picking shaft or crank shaft of the loom,
which may or may not be assisted by pullies and strap, or pegged
pullies and chains, a clutch box or other equivalent being employed for
throwing the wheels in and out of gear when the weaver desires to turn
back the warp. By these means we dispense with the usual heavy
weights and levers, ropes and friction pullies, and are enabled to produce
an evenly woven piece throughout.

page_text: which bearings are capable of sliding backward and forward in tho
groove of the support.
.
It will be seen by any persons practically acquainted with weaving
as soon as the loom is set in motion the rollers B and C will draw
the warp off the warp beam A in such uniform and regular quantities
as is exactly required, so that the piece will be even in picks throughout,
and at the same time the warp will maintain the same tension from one
end to the other. In order to let more or less warp off the warp beam
the pegged pullies H and I may be changed so as to give any number
of picks required in the cloth.
Having thus fully described the nature of this our said Invention, and
shewn in what manner the same is or may be performed, we would have
it understood that we do not confine ourselves to the precise details
herein shewn and described; but we do claim and believe to be new.
within the realm is, the rollers B and C, substantially for the purpose
shewn and described..
In witness whereof, I, the said James Greenwood, for and on behalf
of myself and the said Sam Balme, have hereunto set my hand
and seal, this Twelfth day of January, One thousand eight
hundred and seventy-five.
Witness,
