IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1870

page_text: LETTERS PATENT to Thomas Smith, of Leigh, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN
LOOMS FOR
WEAVING."
Scaled the 24th September 1870, and dated the 5th April 1870.
PROVISIONAL SPECIFICATION left by the said Thomas Smith at
the Office of the Commissioners of Patents, with his Petition, on
the 5th April 1870.
I, THOMAS SMITH, of Leigh, in the County of Lancaster, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN LCOMS
FOR WEAVING," to be as follows:-
This Invention relates to improvements upon a prior Invention for
which Letters Patent were granted to me in conjunction with Robert
Neild and John Yates (bearing date April 6th A.D. 1867, No. 1031) and
consists in an improved method of adjusting and securing the movable
flanges on the warp beam of a loom to accommodate the varying widths
of warps to be woven.

page_text: In carrying out my present Invention I employ longitudinal grooves
in the surface of the warp beam as before, and I mount the movable
flanges thereon, as follows:-Three or more L shaped or right-angled
brackets are bolted or otherwise fixed to the outside of the flange in
such positions as that their bases shall correspond with the longitudinal
grooves, and are each provided with a screw bolt, the head of which
passes into the groove (the section of which latter is of a T shape), a
hole being made at one end sufficiently large to introduce the head of
the bolt. It will be evident that when the nuts of these screw bolts are
slackened the flange may be moved on the beam and adjusted to any
width required, the bolt heads sliding freely in the slots. As soon as
the flanges have been adjusted to the desired position they may be
securely fixed by merely tightening the nuts upon the said screw
bolts, which will cause the heads of the latter to take a firm hold in the
grooves.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Smith in the Great Seal Patent Office
on the 5th October 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
SMITH, of Leigh, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of April, in the year of our
Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto I, the said Thomas Smith, Ier special license that I, the
said Thomas Smith, my executors, administrators, and assigns, or such.
others as I, the said Thomas Smith, my exccutors, 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 POR WEAVING,"
upon the condition (amongst others) that I, the said Thomas Smith,
my executors or administrators, by an instrument in writing under
or their, or one of their hands and scals, should particularly describe
,

page_text: 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Thomas Smith, 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 relates to improvements upon a prior Invention for
which Letters Patent were granted to me in conjunction with Robert
Neild and Joseph Yates (bearing date April 6, A.D. 1867, No. 1031) and
consists in an improved method of adjusting and securing the movable
flanges on the warp beam of a loom to accommodate the varying widths
of warps to be used.
In carrying out my present Invention I employ longitudinal grooves
in the surface of the warp beam as before, and I mount the movable
flanges thereon as follows:-Three or more L shaped or right-angled
brackets are bolted or otherwise fixed to the outside of the flange in
such positions as that their bases shall correspond with the longitudinal
grooves, and are each provided with a screw bolt, the head of which
passes into the groove (the section of which latter is of a T shape),
a hole being made at one end sufficiently large to introduce the head
of the bolt.
Such being the nature and object of my said Invention for "Improve-
ments in Looms for Weaving," I will now proceed to describe more in
detail the manner in which the same is to be or may be performed
or carried into practical effect; and in order that the same may be
clearly understood I have hereunto annexed a Sheet of Drawings.
illustrative thereof, and have marked the same with Figures and
letters of reference corresponding with those in the following explanation
thereof
In the annexed Drawing, Fig. 1 represents a side elevation, and Fig. 2
an end view, of a warp beam fitted with movable flanges according to
my
Invention, and drawn about one-quarter the actual size; Fig. 3 is a
longitudinal section of one end taken through about the line A, B, in
Fig. 1, and Fig. 4 is a transverse section of the same taken through
about the line C, D, in Fig. 1.

page_text: a, a, represents the warp beam, having longitudinal grooves b, b, b,
formed therein, the cross section of the latter being of a T shape as
clearly shown in Fig. 4; c, c, c, are three L shaped brackets bolted
or otherwise fixed to the outside of the flange d, d, and each provided
with a screw bolt c, c, the head of which passes into one of the grooves b,
a hole being formed at the outer end of each groove sufficiently large
to admit the head of the said bolt c. It will be evident that when the
nuts of these screw bolts e, e, are slackened the flange d, d, may be
moved on the beam a, a, and adjusted to any width required, the
bolt heads sliding freely in the slots or grooves b, b, b. As soon as the
flanges have been adjusted to the desired position they may be securely
fixed by merely tightening the nuts upon the said screw bolts e, e, e,
which will cause the heads of the latter to take a firm hold in the
grooves b, b, b..
Having now described the nature and object of my said Invention
together with the manner in which the same is to be or may be per-
formed or carried into practical effect, I wish it to be understood that
I claim as my Invention the improved method of and apparatus for
adjusting and securing the movable flanges on the warp beam as
herein-before more particularly described and shown on the Drawings
annexed, and more especially I claim the L shaped brackets adjustable
by means of bolts working in longitudinal grooves, substantially as
shown and described, or any merc modification or imitation thereof
constructed and operating in substantially the same or a similar
manner.
In witness whereof, I, the said Thomas Smith, have hereunto set
my hand and seal, this Third day of October, in the year of our
Lord One thousand eight hundred and seventy.
