IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1874

page_text: LETTERS PATENT to Nathan Robinson, Manufacturer, and. Thomas
Hird, Overlooker, both of Bradford, in the County of York, for the
.
PROVISIONAL SPECIFICATION left by the said Nathan Robinson and
Thomas Hird at the Office of the Commissioners of Patents, with
their Petition, on the 20th June 1874.
We, NATHAN ROBINSON, Manufacturer, and THOMAS HIRD, Over-
looker, both of Bradford, in the County of York, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING,"
to be as follows:-
:—
This Invention relates specially to the weaving of "reps" or goods
requiring a varying supply of warp. This we effect by the use of two
or more warp beams, friction rollers, and guide rods, such beams and
friction rollers being supported on fixings; and the friction rollers are

page_text: connected with each other by means of gear wheels of such diameter
respectively as will cause one beam to give off more warp than the
other, admitting the weaving of reps and similar goods evenly
throughout, the warp being passed from cach beam to, over, or
partially around the friction rollers; and guide rods are employed for 5
keeping the warp in contact with the friction rollers.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Nathan Robinson and Thomas Hird in the Great
Seal Patent Office on the 19th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, NATHAN
ROBINSON, Manufacturer, and THOMAS HIRD, Overlooker, both of Brad-
ford, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of June, 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 successors,
give and grant unto us, the said Nathan Robinson and Thomas Hird,
Her special licence that we, the said Nathan Robinson and Thomas
Hird, our executors, administrators, and assigns, or such others as
wc, the said Nathan Robinson and Thomas Hird, our executors, 2
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 "IMPROVEMENTS IN 2
LOOMS FOR WEAVING," upon the condition (amongst others) that we, the
said Nathan Robinson and Thomas Hird, our executors or adminis-
trators, by an instrument in writing under 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 a
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 Nathan Robinson and Thomas
Hird, 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 and accompanying
Sheet of Drawings, that is to say :-
"
This Invention relates specially to the weaving of " "reps or goods
requiring a varying supply of warp (or in different lengthis or quantities).
This we effect by the use of two or more warp beams, friction rollers,
and guide rods, such beams and friction rollers being supported on
fixings; and the friction rollers are connected with each other by means
of gear wheels of such diameter respectively as will cause one beam to
give off more warp than the other, admitting the weaving of reps and
similar goods evenly throughout. The warp being passed from each
beam to, over, or partially around the friction rollers; and guide rods
arc employed for keeping the warp in contact with the friction rollers.
In order that this Invention may be more clearly understood, we have
hereunto annexed One Sheet of Drawings shewing such parts of a loom
as are necessary to illustrate our improvements.
Fig. 1 is an end elevation; and Fig. 2, a back elevation of the same.
A is a portion of framing of an ordinary loom employed for the
weaving of "reps" or similar goods requiring a varying supply of warp;
B and C are two friction rollers supported in slide plates or bearings D
which are secured to the upright standard E and capable of adjustment
thereon to the distances that the said rollers require to be set apart from
each other, which varies according to the gearing employed; the
upright standard E is attached to a bracket F, and is capable of being
moved or adjusted laterally thereon. In the said slide plates or bear-
ings D we also mount two guide rods G and G'; H and H¹ are gear
wheels which we mount on the ends of the shafts of the friction rollers
B and C, and the said wheels may be varied or made of such diameters
respectively as to cause one beam to give off more warp than the other,
whereby the " reps or other similar goods are wove evenly throughout;
the warps passing from the ordinary warp beam J over the guide
rod G¹, thence under the friction roller C, and from the beam K under
the guide rod G, and thence over the friction roller B, in manner as
shewn in Fig. 1 of the Drawings.
"

page_text: It will be seen that by causing the warps to be delivered by friction
or surface rollers instead of direct from the beams, the same quantity of
warp is given off at each revolution of the said rollers.
Having thus described the nature of our said Invention, and shewn
by Drawings how the same may be put into practice, we would have it
understood that we do not confine ourselves to the precise details of
construction as herein described and illustrated; but what we claim is,
the use or employment of friction rollers geared together so as to rotate
at different surface speeds, for delivering two or more warps in regular
and in different quantities from two or more warp beams, in manner
substantially as shewn and described.
"
In witness whereof, I, the said Nathan Robinson, for and on
behalf of myself and the said Thomas Hird, have hereunto set
my hand and seal, this Seventeenth day of December, in the year
of our Lord One thousand eight hundred and seventy-four.
