Improvements in Shuttle Guards for Looms.
We GEORGE FITTON, of 64 William Street, Heywood, Mill Manager, JAMES
KEELTY, of 49 Kershaw Street, Bury, Loom Overlooker, and THOMAS LOMAX, of
92 Shadwell Street, Heywood, Loom Overlooker, all in the County of Lancaster, do
hereby declare the nature of this invention to be as follows:-
This invention relates to the wire guard used for preventing the shuttle from flying
out of the shuttle race while the loom is running, and the invention consists principally
of a special arrangement whereby the shuttle guard, which is normally held in
position over the race, can be moved back under the slay cap when required, say for
piecing up an end or replacing a cop, and will automatically return into position at
the first beat up of the slay when the loom is put in inotion again.
The wire guard itself is made in the usual form at the centre cranked downwards
from its bearings or brackets, but each of these brackets for the sake of cheapness,
cleanliness, lightness, and durability, is made of a strip of doubled buffalo hide
looped or opened out to form a bearing, and bolted or otherwise secured to the stay
cap.
One end of the wire guard is bent cranked or otherwise so shaped as to bear
against the slay cap and form a stop to retain the guard in working position. The
other end of the wire guard is cranked and attached by a spring to a bracket fixed
to the slay cap in such a position with regard to the crank and the rocking centre
of the wire guard that it will hold the said guard firmly in place when in working
position but when moved out of the way beneath the slay cap the said crank will
only just have passed its dead centre. It will therefore be held in this position by
the spring only so long as the loom and its slay is at rest, but as soon as the loom
is again set in motion the first beat up of the slay will cause the guard to jerk
back again of its own weight into working position. We propose to make the
bracket to which the spring is attached adjustable on the slay cap so that the
guard can be set with the greatest nicety to act automatically and without fail as
above described.

page_text: Loom Overlooker, all in the County of Lancaster, do hereby 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 the wire guard used for preventing the shuttle from
flying out of the shuttle-race while the loom is running, and the invention
consists principally of a special arrangement whereby the shuttle guard, which is
normally held in position over the race, can be moved back under the slay cap
when required, say for piecing-up an end or replacing a cop, and will automatically
return into position at the first beat-up of the slay when the loom is put in
motion again.
The manner in which our said invention is to be performed or carried into
practical effect will be readily understood on reference to the sheet of drawings
hereunto annexed and the following explanation thereof.
Fig. is a partial front elevation of the slay-cap of a loom with our improved
shuttle-guard shown as applied thereto, and Fig. 2 is a vertical section of the
same. Figs. 3 and 4 are similar views of a slight modification of the same
hereinafter more particularly described. Referring to Figs. 1 and 2 of the drawing, a
is part of the slay-cap of the loom which supports the upper part of the reed.
b is the wire shuttle-guard which is made in the usual form at the centre
cranked downwards at 6 from its bearings or brackets c each of which for the
sake of cheapness, cleanliness, lightness and durability is made of a strip of
double buffalo-hide looped or opened out to form a bearing and bolted or otherwise
secured to the front of the slay-cap a, say by the piece c* of metal bolted together
(as shown at Fig. 4).
One end of the wire guard 6 is bent or cranked upwards at 6 or otherwise so
shaped as to bear against the slay cap a and form a stop to retain the guard in
working position, a piece of leather or other substance d being interposed between
the metal and the wood. The other end of the wire-guard is also cranked upwards
and backwards (as shown at 611) and attached by a coiled spring e to a bracket f
which is fixed to the front of the slay-cap so as to pull the crank 6 downwards as
shown at Figs. 1 and 2, or it may be fixed to the metal part ex of the bearing by
the same bolt which also fixes the buffalo strip c (as shown at Figs. 3 and 4). In
either case the form and position of this bracket f with regard to the crank 61, and the
rocking centre of the wire guard b, are such that it will pull the crank b¹¹ downwards
and hold the said guard firinly in place when in working position as drawn in full
lines, but when moved out of the way beneath the slay-cap a by the weaver (for
piecing or otherwise) the said crank will only just have passed the dead centre as
shown by the dotted lines on Figs. 2 and 4, the spring acting downwards in both
positions. It will therefore be held by the spring e in this position only so long as
the loom and its slay is at rest, but as soon as the loom is again set in motion the
first "beat-up "of the slay will cause the shuttle guard b to be jerked back by
its own weight into working position. We propose to make the bracket f to which
the springe is attached adjustable so that the guard can be set with the greatest
nicety to act automatically and without fail as above described.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is:-
The improvements in automatic shuttle guards for looms substantially as
herein before described and illustrated by the drawings annexed.
