IMPROVEMENTS IN LOOMS FOR WEAVING."
Year: 1879

page_text: LETTERS PATENT to George Keighley, of Burnley, in the County of Lancaster,
Machinist, for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said George Keighley at the
Office of the Commissioners of Patents on the 25th February 1879.
GEORGE KEIGHLEY, of Burnley, in the County of Lancaster, Machinist. "IM-
PROVEMENTS IN LOOMS FOR WEAVING."
This Invention relates to the construction of metal "slays" employed in looms as
a substitute for wood slays; up to the present time the use of metal slays has been
attended with many drawbacks, as they have either been too heavy, causing a
great waste of power, or liable to breakage if made lightly, or else their construction
has been too costly. My improvements are calculated to remedy these defects, and
will be understood by reference to the accompanying Sheet of Drawings.
The body or central part of the slay may be of wrought iron of the sectional
forms shewn in Figs. 1, 2, 3, 4, and marked with the letter A. The shuttle boxes
may be of similar section and metal, or they may be formed separately of cast
metal. The slays swords B serve to form the backs of the shuttle boxes, the
swells C completing the same.
The swells are mounted on studs c, and can be
removed so that the shuttle boxes can be cleaned readily.
The reed case is formed, by preference, of wood D, and is bolted to the slay so
that the space for the reed can be enlarged or contracted by means of packing.
Figs. 5 and 6 represent elevation and plan of slay for fast reed loom, Fig. 3
being section for same; Figs. 7 and 8 are elevation and plan of loose reed slay, of
which Fig. 4 is section; Figs. 9 and 10 are elevation and plan of shuttle box with
the back E formed thereon instead of the back being formed by the slay sword, but
this latter plan is preferable.
In loose reed looms the reed is kept in its place by the usual means.

"IM-
This Invention relates to the construction of metal "slays" employed in looms
as a substitute for wood slays.
Up to the present time the use of metal slays has been attended with many
drawbacks, as they have either been too heavy, causing a great waste of power, or
too light and liable to breakage, or else they have been too costly in construction.
My improvements are calculated to remedy these defects, and will be under-
stood by the following description, reference being therein given to the annexed
Sheet of Drawings marked with figures and letters. Fig. 1 is a front elevation ;
Fig. 2, a plan view; Fig. 3, a back elevation; and Fig. 4, a cross section of a cast
iron or other cast metal slay constructed according to my Invention for application
to a fast-reed loom. The central part or body of the slay is made in the form
shown in Fig. 4, and is planed or otherwise made true on its face a, that part which
forms the bottom of the shuttle box b being made in the form shown in Fig. 5,
which is a section through the line O, P, in Fig. 1. The top of the slay swords d,
together with the swells e serve to answer the same purpose as the ordinary shuttle
box backs. The swells e being mounted on studs can be removed, and the shuttle
boxes readily cleaned. By thus dispensing with the ordinary shuttle box backs I
reduce the weight of material employed in the construction of metal slays where it
is most objectionable, and am enabled to construct a metal slay that is light and
not liable to break and at a moderate cost.
The reed case g is constructed by preference of wood of the form shown in Fig. 4,
and is bolted or otherwise secured to the slay, so that the space h for the reed can
be enlarged or contracted by means of packing. And in order to prevent the edge
of the slay from cutting the face of the reed I employ a spring i, which is so
arranged as to keep the face of the reed entirely clear of the edge of the slay.
Fig. 7 is a section of a slay constructed of steel or wrought iron, j being the
reed case.
Fig. 8 is a front elevation; Fig. 9, a plan view; and Fig. 10, a section of a metal
slay constructed according to my Invention for application to a loose-reed loom;
the reed being in this case held in its position by the usual means.
The front part of the box back k, which is usually of wood, and attached to the
back part of the box back by a spring is in this case hung on a stud l, as shewn in
Figs. 8 and 9.
Having now stated the nature of my Invention, and shown by Drawings how
the same is to be performed, I would have it understood that I do not limit myself
to the exact details given, and that I claim,-
Firstly. The improved mode of constructing the shuttle boxes of metal slays by
which means the ordinary shuttle box backs are dispensed with, as and for the
purpose herein shown and described.
Secondly. The improved mode of constructing the reed cases employed with
metal slays in the fast reed loom, as described and shown in Figs. 2 and 4.
Thirdly. The improved mode of preventing the edge of the metal slay from

page_text: cutting the face of the reed either in a fast or loose reed loom in the manner
herein described, and shown in Figs. 2 and 4.
In witness whereof, 1, the said George Keighley, have hereunto set my
hand and seal, this Twenty third day of August, in the year of our Lord
One thousand eight hundred and seventy nine.
