Improvements in or in Connection with Certain Parts of the Looms
in which Bands, Ribbons, Tapes, and the like are Woven.
We HENRY BURGESS, of Congleton, in the County of Chester, Manufacturer,
THOMAS BURGESS, of Congleton aforesaid, Manufacturer, and CHARLES CLAY of
Dale Street, Manchester, in the County of Lancaster, Hat Trimming Dealer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the head rail, the top castle or other
parts of smallware looms (or looms in which such articles as bands, tapes, ribbons and
the like, varying from of an inch to 6 inches in width are woven) over which the
manufactured article passes as it leaves the loom and to which it is now secured
during a part of the process by means of wedges.
In this class of loom as is well known the texture of the cloth is regulated or the
number of shots of weft yarn per inch is determined by weights suspended on the
warp yarn and on the manufactured article, the speed of travel being determined by
the relative weight of the weights used. It is necessary that the finished article should,
after it has passed through the loom be held tightly to suspend the weight hung upon
it. This has hitherto been done by the use of wedges passed into holes in the head
rail or top castle of the loom, carrying the article with them and wedging it in the
said holes. This is objectionable in that the friction and pressure of the wedges on
the woven material especially when of a dull black colour causes a gloss or shine
different from the other portions of the cloth, and also occupies considerable time in
withdrawing and re-inserting the wedges when a given length has been woven.
The object of our invention is to obviate these defects and provide means whereby
the material may be held without the use of wedges, and without the consequent
marking of it and which will allow of the quick and ready movement forward of each
given length of the woven material.
It consists essentially in forming the head rail, top castle or other part of the loom
over which the material passes with, or in combining with it, a pivoted catch or
eccentric piece which will allow the woven material to be passed forward in one
direction but will hold it and prevent it moving in a backward direction.
In carrying out the invention we construct the head rail or the back rail of the top
castle of plain bars without wedge holes cut in them and to either of these we affix a
small catch or bracket to which is pivoted a small elbow or eccentric catch so pivoted
that when moved in one direction it bears against the back plate of the bracket or the
bar to which it is attached and when moved in the opposite direction recedes there-
from. The ribbon band or other article woven is passed beneath this catch, which grips
it and holds it firm against a backward movement but allows it to be advanced
periodically in a forward direction.

COMPLETE SPECIFICATION.
Improvements in or in Connection with Certain Parts of the Looms
in which Bands, Ribbons, Tapes, and the like are Woven.
We, HENRY BURGESS, of Congleton, in the County of Chester, Manufacturer,
THOMAS BURGESS, of Congleton, aforesaid, Manufacturer, and CHARLES CLAY of Dale
Street, Manchester, in the County of Lancaster, Hat Trimming Dealer, do hereby
.

page_text: declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement
This invention relates to improvements in the top castle, head rail, or other parts of
smallware looms (or looms in which such articles as bands, tapes, ribbons, and the
like, varying from of an inch to 6 inches in width are woven) over or against which
the manufactured article passes, before it leaves the loom and to which it is now
secured during a part of the process by means of wedges thrust into holes therein.
In this class of loom, as is well known, the texture of the cloth is regulated, or the
number of shots of weft yarn per inch is determined by weights suspended on the
warp yarn and on the manufactured article, the speed of travel being determined by
the relative weight of the weights used. It is necessary that the finished article
should, after it has passed through the loom, be held tightly to suspend the weight
hung upon it. This has hitherto been done by the use of wedges passed into holes in
the head rail or top castle of the loom, carrying the article with them and wedging it
in the said holes. This is objectionable in that the friction and pressure of the
wedges on the woven material, especially when of a dull black colour, causes a gloss
or shine different from the other portions of the cloth, and also occupies considerable
time in withdrawing and reinserting the wedges when a given length has been
woven.
The object of our invention is to obviate these defects and provide means whereby
the material may be held without the use of wedges, and without the consequent
marking of it and which will allow of the quick and ready movement forward of each
given length of the woven material.
It consists essentially in forming the head rail, top castle, back rail, or other part
of the loom over which the material passes with, or in combining with it, a pivoted
catch or eccentric piece which will allow the woven material to be passed forward in
one direction but will hold it and prevent it moving in a backward direction.
Referring to the annexed drawings:-
Fig. 1, sectional outline of sufficient parts of a smallware loom to illustrate the
invention.
Fig. 2, front elevation of eccentric clip.
Fig. 3, transverse section of fig. 2.
Fig. 4, front elevation of slightly modified form of clip.
Fig. 5, transverse section of fig. 4.
As shown in fig. 1, (the dotted lines represent a slightly different construction of
loom) we construct the back rail A, and head rail B, of the top castle, of plain bars,
without wedge holes cut in them, and to the back rail A, (or head rail B) we affix
a number of small eccentric or spring catches C, to take the place of the wedges,
preferably one for each band, tape, etcetera, issuing from the loom.
The catch C, is constructed as shown in Figs. 2-5. An eccentric piece c,
preferably of shape is pivoted to the lugs d of a bracket D. The extremity of the
piece c, extends downward to form a handle to raise it and a weighted lever to keep
it in position The catch C, shown in Figs. 2 and 3, is made of sheet metal, cut or
stamped to the required shape, the back piece D, carrying two lugs d, through which
the pin E, passes. The front or eccentric catch piece c, has lugs or ear pieces c¹,
through which the pin E, also passes, the pin forming a pivot for the eccentric catch
piece c, to move upon. Above the eccentric catch piece c, is a second pin F, to
prevent it rising too high. Around the pin F, is coiled a spring G, to hold the
catch piece c, against the material. Instead of the pin F, to carry the spring it may
be coiled upon the pin E.
In figs. 4 and 5, the catch C, is shown as made of cast iron, the bracket D, and
lugs d, are cast in one piece, and the eccentric catch piece c, is cast separately, with a
weight c, along the under edge. It is pivoted on the pin E, which is passed through
the lugs & and c, and rivetted in position. Instead of the pin F, to prevent the
eccentric catch piece c, being raised or jerked too high, a little projecting piece f,

page_text: (shown in dotted lines) may be cast to the lugs d, against which the short arm
of the eccentric catch piece would come in contact when moved beyond a proper
distance.
Instead of the pin F, extending across the catch, a short pin from the lug d to the
lug c', may be employed.
In action the woven material H, will pass from the loom in the ordinary way,
following the course shown in the direction indicated by the arrows, and will pass
through the catch C, on the back rail A. The catch (), will grip and hold the
material and prevent the weight I pulling it in a backward direction. When a length
of the material is woven and it is intended to take up the slack, it is pulled in a
downward direction through the catch C, which allows it to pass freely but grips it
again' as soon as the pull upon it is in the opposite direction.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
:-
In a smallware loom the combination with the top castle, head-rail, back-rail, or
other similar part of the loom, of eccentric or spring catches such as C, to hold and
grip the material, substantially as and for the purposes described.
