IMPROVEMENTS IN LOOMS FOR WEAVING ELASTIC FABRICS
Year: 1873

page_text: LETTERS PATENT to Luke Turner, of Leicester, Elastic Web Manu-
facturer, for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING
ELASTIC FABRICS."
Sealed the 16th January 1874, and dated the 20th November 1873.
PROVISIONAL SPECIFICATION left by the said Luke Turner at the
Office of the Commissioners of Patents, with his Petition, on the
20th November 1873.
I, LUKE TURNER, of Leicester, Elastic Web Manufacturer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN LOOMS FOR
WEAVING ELASTIC FABRICS," to be as follows:-
The object of my Invention of improvements in looms for weaving
elastic fabrics is to produce a uniform and regular fabric with an
improved face, and by the introduction of an increased quantity of weft
to produce an elastic fabric of greater solidity than heretofore; this is
effected by adapting to the breast beam of the loom two or more guide
or tension rollers or bars over and under which the fabric when woven
passes to the taking-up roller,
.

page_text: In carrying out my Invention I prefer to use four rollers or bars,
although three and even two will act satisfactorily. These four rollers
or bars may be mounted or fixed on a plate or frame which may be
secured in any convenient manner to the breast beam. They may be
arranged one above another in pairs, and the elastic fabric is conducted
over and under the rollers or bars. The effect of this (when rollers are
employed) will be that when the slay beats up the weft an intermittent,
alternating, or vibrating rotary motion will be imparted to the first pair
of rollers, while the second pair will have only a simple or intermittent
motion in one direction, and thus no jumping or reciprocating motion
will be given to the fabric between the breast beam or roller and the
taking-up roller, as is now the case. When fixed bars are employed the
friction produced by the passage of the fabric over the surface of the
bars will be sufficient to prevent the fabric from jumping or moving to
and fro, but will cause it to move forward with an intermittent but
uniform onward motion instead of reciprocating to and fro as here-
tofore.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Luke Turner in the Great Seal Patent Office on
the 19th May 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LUKE
TURNER, of Leicester, Elastic Web Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of November, in the
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Luke Turner, Her special
licence that I, the said Luke Turner, my executors, administrators,
and assigns, or such others as I, the said Luke Turner, 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 "IMPROVEMENTS IN LOOMS
FOR WEAVING ELASTIC FABRICS," upon the condition (amongst others)

page_text: that I, the said Luke Turner, my executors, or administrators, by an
instrument in writing under my, 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 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 Luke Turner, 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, reference being had to the Drawing
hereunto annexed and to the letters and figures marked thereon (that is.
to say) :-
The object of my Invention of "Improvements in Looms for Weaving
Elastic Fabrics" is to produce an uniform and regular fabric with an
improved face, and by the introduction of an increased quantity of weft,
to produce an elastic fabric of greater solidity than heretofore. This is
effected by adapting to the breast beam of the loom two or more guide
or tension rollers or bars over and under which the fabric when woven
passes to the taking-up roller.
In Fig. 1 of the accompanying Drawing I have shewn in vertical
section so much of a loom for weaving elastic fabrics as will be sufficient
to explain the nature of my Invention. a is the ordinary breast beam
of the loom and 6 the slay. On the top of the breast beam a is fixed a
metal plate or frame c³, c¹, shewn full size in plan and sectional view
at Figures 2 and 3, in which are mounted four guide or tension rollers
C, C, C, C.

In carrying out my Invention I prefer to use four tension rollers or
bars, although three and even two will act satisfactorily, but not so well
as the larger number. These tension rollers may be arranged in pairs
one above another, as shewn in the Drawing, or at different levels, and
the elastic fabric is conducted over and under the rollers in the manner
hereafter explained. The woven fabric d, d, passes under the first roller
of the lower pair, then up and over the first roller of the upper pair.
From thence it passes down to and under the second roller of the lower
pair, and up to and over the last tension roller, which belongs to the
upper pair. The fabric then passes down through a slot in the breast

roller f, from whence it passes to the work roller g in the ordinary
manner. The effect of this arrangement of parts (when rollers are
employed as shewn in the Drawing) will be that when the slay beats up
the weft an intermittent alternating or vibrating rotary motion will be
imparted to the first two rollers, while the other two will have only a
simple or intermittent or rotary motion in one direction, and thus no
jumping or reciprocating motion will be given to the fabric between the
breast beam or last roller c and the taking-up roller, as is now the
case.
· In place of all the rollers c, c, being moveable, as shewn in the Drawing,
one or more fixed round bars may be employed in combination with one
or more rollers, and when this is the case the friction produced by the
passage of the fabric over the surface of the bars will be sufficient to
prevent the fabric from jumping or moving to and fro; but will cause it
to move forward with an intermittent but uniform onward motion instead
of reciprocating to and fro as heretofore.
Having now described my Invention of "Improvements in Looms for
Weaving Elastic Fabrics," and having explained the manner of carrying
the same into effect, I claim as the Invention secured to me by Letters
Patent as aforesaid, adapting to the breast beam of looms two, three,
or more tension or guide rollers or bars under and over which the woven
fabric is conducted on its way from the slay to the taking-up roller, as
and for the purposes herein set forth.
In witness whereof, I, the said Luke Turner, have hereunto set
my hand and seal, the Twelfth day of May, in the year of our
Lord One thousand eight hundred and seventy-four."
