CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1867

page_text: LETTERS PATENT to Robert Neild, of Leigh, in the County of Lancaster,
Cotton Manufacturer, Thomas Smith, of the same Place, Overlooker,
and John Yates, of the same Place, Cotton Manufacturer, for the
PROVISIONAL SPECIFICATION left by the said Robert Neild, Thomas
Smith, and John Yates at the Office of the Commissioners of Patents,
with their Petition, on the 6th April 1867.
We, ROBERT NEILD, of Leigh, in the County of Lancaster, Cotton Manu-
facturer, THOMAS SMITH, of the same Place, Overlooker, and JOHN YATES, of
the same Place, Cotton Manufacturer, do hereby declare the nature of the
said Invention for "CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING," to be as
follows:-
Our Invention relates to that part of the loom called the warp beam, and is
designed for the purpose of diminishing or increasing the width of that portion
of the beam on. which the warp is wound, so as to be adjustable and to accom-
nodate the varying widths of warps.
The Invention consists in the employment of adjustable flanges which move
in slots in the beam in the direction of its length, and these flanges are secured

page_text: in any position or at any distance from each other as required by an arrange-
ment of internal and external telescopically expanding screws, one end of each
being secured to the moveable flange and the other to a fixed flange and
collar secured to each end of the beam, around which collar the ordinary
weighted rope passes; thus, when the flanges are adjusted to the width of the
warp, they are "set up" or secured in such position by the expanding screws,
or other means, such as bolts and washers, may be employed for the purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Neild, Thomas Smith, and John Yates in the Great
Seal Patent Office on the 4th October 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
NEILD, of Leigh, in the County of Lancaster, Cotton Manufacturer, THOMAS
SMITH, of the same Place, Overlooker, and JOHN YATES, of the same Place,
Cotton Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of April, in the year of our Lord One
thousand eight hundred and. sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Robert Neild, Thomas Smith, and John Yates, Her special license that we, the
said Robert Neild, Thomas Smith, and John Yates, our executors, adminis-
trators, and assigns, or such others as we, the said Robert Neild, Thomas
Smith, and John Yates, our executors, administrators, and assigns, should at
any time agree with, and no others; from time to time and at all times there-
after 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 IMPROVE-
MENTS IN LOOMS FOR WEAVING," upon the condition (amongst others), that we,
the said Robert Neild, Thomas Smith, and John Yates, 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 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 John Yates, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say) :—
Our. Invention relates to that part of the loom called the warp beam, and is
designed for the purpose of diminishing or increasing the width of that portion
of the beam in which the warp is wound, so as to be adjustable and to
accomodate the varying widths of warps.
The Invention consists in the employment and use of adjustable flanges,
which move in slots in the beam in the direction of its length, and these flanges
are secured in any position or at any distance from each other as required. by
an arrangement of internal and external telescopically expanding screws, one
end of each being secured to the moveable flange and the other to a fixed
flange and collar secured to each end of the beam, around which collar the
ordinary weighted rope passes; thus, when the flanges are adjusted to the width
of the warp. they are "set-up" or secured in-such position by the expanding
screws, or other means, such as bolts and: washers, may be employed for the
purpose.
.
In order that the Invention may be better understood and explained in
detail we have hereunto attached a Sheet of Drawings illustrative of the
same.
Fig. 1 represents a front elevation of the warp beam mounted in the loom
framing, both ends of the said beam being fitted with the adjustable flanges,
which with the apparatus for adjustment are shewn in section at one end,
and an elevation at the opposite end; Fig. 2 represents an end view of the
flange and the beam in section, shewing the grooves therein in which the studs
on the flange slide; this view shews the application of three adjustments as an
example.
In Figs. 1 and 2 a, a, represents the framing of the back part of a loom in
which the warp beam is supported; and c, c, are the flanges, which are
capable of being moved in the slots d, d, in which the studs e, e, slide; and
f, f, are the end plates or collars fixed onto each end of the warp beam, between
which are the flanges the telescopically expanding male and female screws g, g,
pin h, and washers i, i, are placed. It will be evident that the flanges may
be brought nearer together or further apart by the simple use of the expanding
screws, or by the addition of tubes or washers, according to the distance each
flange is required to be from its end plate or collar, the advantage of such
adjustment being the adaptation thereby of any warp beam to varying widths
of the warp.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, we wish it to be distinctly

page_text: understood that we claim the novel application, employment, and use of
moveable flanges on the warp beams of looms having internal and external
telescopically expanding screws to retain them in position; as herein-before
described, set forth, and fully illustrated in the Drawings attached.
In witness whereof, I, the said John Yates, have hereunto set my hand
and seal, this Second day of October, in the year of our Lord One
thousand eight hundred and sixty-seven.
