Improvements in Shuttle Guards of Looms for Weaving.
I, Doctor CHARLES BAYNES, of Kuuzden Brook, Blackburn, in the County of
Lancaster, Machinist, do hereby declare the nature of this invention to be as
follows: -
This invention relates to improvements in shuttle guards of looms for weaving,
and has for its object such a construction as shall diminish the chance of damage
to the operative's fingers if trapped between the guard and the temple roller;
and shall offer little obstruction to the view of the shuttle race; and be simple
and inexpensive; and the invention is applicable to that class of guards in which
a metal rod is hinged to the reed cap, and when the loom is set in motion can
automatically swing from an inner inoperative to an outer operative position.
The invention consists in the use and employment of a thin elastic spring to
catch, and hold the rod in its operative position, and the spring is so formed that
it holds the guard when in its operative position, prevents detrimental vibration
of the guard due to the working of the loom, and gives to the guard such flexi-
bility as to diminish the chance of damage to the fingers if trapped between the
guard and the temple roller.
In the form in which I prefer the guard, hinged to the reed cap, can be folded
back against the reed cap to the inoperative position but will automatically fall
down to the operative position over the shuttle race when the loom is set in motion,
and the spring is preferably bent or curved nearly to the are described by the
guard when turned on its hinges. The outer end of the spring is bent so as to
form a holding device and stop for the guard when in its outer or operative
position, and the spring is set in such position, and so shaped as to be deflected
by the guard as it passes from the inoperative to the operative position and
thereby vibration due to the working of the loom is prevented.
The spring hereinbefore described is equally applicable to guards which fold
up close underneath the reed cap when in the inoperative position.

Improvements in Shuttle Guards of Looms for Weaving.
I, Doctor CHARLES BAYNES, of Knuzden Brook, Blackburn, in the County of
Lancaster, Machinist, 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 improvements in shuttle guards of looms for weaving
and has for its object such a construction as shall diminish the chance of damage

page_text: to the operatives fingers if trapped between the guard and the temple roller, and
shall offer little obstruction to the view of the shuttle race, and be simple and
inexpensive, and the invention is applicable to that class of guards in which a
metal rod is hinged to the reed cap, and when the loom is set in motion can auto-
matically swing from an inner inoperative to an outer operative position.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which:-
Fig. 1 is a front elevation of the reed cap and shuttle guard complete.
Fig. 2 is a cross section of the reed cap and guard, shewing the guard in its
operative position.
Fig. 3 is a similar view shewing the guard in its inoperative position, i.e. folded
close to the reed cap.
According to this invention, the improvement consists in the use and employ-
ment of a thin elastic spring 1 to catch and hold the rod or guard 2 in its operative
position (see Fig. 2) and the spring 1 is so formed that it holds the guard when
in its operative position and prevents detrimental vibration of the guard 2 due
to the working of the loom, and gives to the guard 2 such flexibility as to diminish
the chance of damage to the fingers if trapped between the guard 2 and the
temple roller.
In the form in which I prefer, the guard 2 is hinged at each end to the reed
cap 4 and can be folded back against the reed cap 4 to the inoperative position
(see Fig. 3) but will automatically fall down to the operative position over the
shuttle race when the loom is set in motion, and the spring 1 is preferably bent
or curved nearly to the arc described by the guard 2 when turned on its hinges 8.
The outer end of the spring 1 is bent in the form of a hook 7 so as to form a hold-
ing device and stop for the guard 2 when in its outer or operative position, and
the spring 1 is set in such position and so shaped as to be slightly deflected by
the guard 2 as it passes from the inoperative to the operative position and thereby
vibration of the guard due to the working of the loom is prevented.
The spring 1 which constitutes the holding device is preferably made from
soft sheet steel cut to the required shape and then bent to the forms shewn and
this constitutes a spring or elastic holder and from its pliability it is little likely
to break.
The holding device may be set or bent so as to press on and hold the guard in
its operative position, but this is not a necessity, as in practice it is found that the
weight and inertia of the guard without assistance from the holding device will
deflect or prevent the shuttle flying out, but I prefer that the holding device
should by its pressure assist the guard and also break the velocity of its fall when
assuming the operative position.
The spring 1 herein before described is equally applicable to guards which fold
up close underneath the reed cap. 4 when in the inoperative position.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
A rod or guard hinged to the reed cap and combined with a spring or thin
pliable holding device as and for the purpose herein described and substantially
as illustrated by the annexed drawings.
