IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1879

page_text: LETTERS PATENT to Samuel Hopkinson, of Penwortham, near Preston, in
the County of Lancaster, and William Hopkins and Thomas Martin, both of
Farington, near Preston, in the County of Lancaster, for the Invention of
"IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 22nd August 1879, and dated the 20th May 1879.
PROVISIONAL SPECIFICATION left by the said Samuel Hopkinson, William.
Hopkins, and Thomas Martin at the Office of the Commissioners of Patents
on the 20th May 1879.
SAMUEL HOPKINSON, of Penwortham, near Preston, in the County of Lancaster,
and WILLIAM HOPKINS and THOMAS MARTIN, both of Farington, near Preston,
in the County of Lancaster. "IMPROVEMENTS IN LOOMS FOR WEAVING."
This Invention of improvements in looms for weaving relates to providing
means for adjusting and regulating the position of the reed relatively to the slay.
One arrangement consists in firmly affixing to the slay cap opposite an opening or
slot in the upper end of the slay sword a screw bolt, the end of which projects some-
what beyond the back of the slay cap. The projecting part is screwed or threaded,
and has mounted upon it two screw nuts, between which the upper end of the slay
sword is securely held.
It will be evident that by turning the nuts backwards or forwards upon the
projecting bolt, the slay cap may be moved and secured in a position nearer to or
further from the slay sword; thus the angle of the reed which is held between the
slay cap and the slay bottom may be readily adjusted so as to be set parallel with
the side of the shuttle and with the shuttle box.
Other arrangements for adjusting and regulating the distance between the upper
end of the slay sword and the slay cap may be employed, as, for instance, instead
of two nuts on the projecting bolt, as above described, only one (the outer one) may
be used, and in place of the second (or inner) nut two or more set screws screwed
through the slay sword from the back may be caused to bear against a metal guard
in the back of the slay cap, the nut serving to fasten the slay sword to the slay
cap, whilst the set screws serve to regulate the distance between the sword and the
cap, and consequently the angle of the reed relatively to the slay, as herein before
mentioned.

the said Samuel Hopkinson, William Hopkins, and Thomas Martin in the
Great Seal Patent Office on the 19th November 1879.
SAMUEL HOPKINSON, of Penwortham, near Preston, in the County of Lancaster,
and WILLIAM HOPKINS and THOMAS MARTIN, both of Farington, near Preston, in
the County of Lancaster. "IMPROVEMENTS IN LOOMS FOR WEAVING."
This Invention of improvements in looms for weaving relates to providing
means for adjusting and regulating the position of the reed relatively to the slay.
One arrangement consists in firmly affixing to the slay cap opposite an opening or
slot in the upper end of the slay sword a screw bolt, the end of which projects some-
what beyond the back of the slay cap. The projecting part is screwed or threaded,
and has mounted upon it two screw nuts, between which the upper end of the slay
sword is securely held.
In the accompanying Drawings Fig. 1 is an end view, of which A is the slay
cap; B, the slay sword; C, D, screw nuts mounted upon the screw bolt E. It will
be evident that by turning the nuts C, D, backwards or forwards upon the pro-
jecting bolt E, the slay cap A. may be moved and secured in a position nearer to or
further from the slay sword B; thus the angle of the reed F, which is held between
the slay cap A and the slay bottom G, may be readily adjusted so as to be set
parallel with the side of the shuttle and with the shuttle box.
Other arrangements for adjusting and regulating the distance between the upper
end of the slay sword and the slay cap inay be employed, as, for instance, instead
of two nuts on the projecting bolt, as above described, only one (the outer one C).
may be used (see Fig. 2), and in place of the second (or inner) nut D, two or more
set screws a, a, screwed through the slay sword B from the back, may be caused to
bear against a metal guard b in the back of the slay cap A, the nut C serving to
fasten the slay sword B to the slay cap A, whilst the set screws a, a, serve to regu-
late the distance between the sword B and the cap A, and consequently the angle of
the reed relatively to the slay, as herein before mentioned.
In Figs. 3 and 4 the slay cap A is fastened to the upper end of the slay sword B
by the screw bolt H. The upper portion K of the slay sword B is mounted upon a
slide I, and by means of the fastening screws J, J, the slay cap may be secured in
position upon the reed F having been adjusted to the required angle.
Figs. 5 and 6 illustrate a means for taking up the play of the reed in the slot or
space M of the slay cap A, thereby affording increased facilities for securing the reed
in the required position (in "loose reed" looms). Fig. 5 is a view of the underside
of one end of the slay cap, and Fig. 6 a side view of the same shewn detached from
the slay sword. The rib L is made separate from the cap A, so as to be adjustable
sideways, and thereby capable of bearing upon the reed in the slot or space M. The
rib L is affixed to the nuts or V pieces N (shewn in dotted lines), fitted in suitably
formed grooves or slides. The set screw' passes through the nut N, being so
arranged that on turning the screw in one direction the rib L will be moved forward
against the reed, whilst if the secrew be turned in the opposite direction the rib will
be withdrawn, thereby loosening the reed. S is a guard to prevent the screw O
from rotating when the loom is in motion.
The nut D is preferably provided with the holes P, into which a catch pin Q
mounted on a spring R is inserted; thus upon the slay cap being detached from the
slay sword the nut D cannot alter its position upon the bolt E, so that the slay cap
may be re-attached to the slay sword in its former position.
Having described the nature of our said Invention, and explained in what manner
the same is to be or may be performed or carried into practical effect, we hereby
declare that we claim as secured to us under the Letters Patent hereinbefore in part

page_text: recited, the methods, substantially as hereinbefore described with reference respec-
tively to Figure 1, to Figure 2, and to Figures 3 and 4 of the accompanying
Drawings, of adjusting and regulating the position of the reed relatively to the
slay.
In witness whereof, I, the said Samuel Hopkinson, for myself and on behalf of
the within named William Hopkins and Thomas Martin, have hereunto set
my hand and seal, this Seventeenth day of November, in the year of our
Lord One thousand eight hundred and seventy nine.
SAMUEL HOPKINSON. (LS.)
