A New or Improved Shuttle Guard for Looms.
We, GEORGE BATEMAN, of 57 Prussia Street, Oldham Road, Power Loom
Overlooker, and HENRY SMITH, of 24 Pitt Street, Ancoats, Maker-up, both in
Manchester in the County of Lancaster, do hereby declare the nature of this
invention to be as follows:-
This invention relates to shuttle guards for looms, and its object is to provide a
guard which shall be efficient in action and which shall be cheap and simple in its
construction and application.
A guard constructed according to this invention consists of two bars, plates or the
like, movably connected together by two or more pivoted links. The bars or plates
are thus capable of moving relatively to one another but are always parallel.
They are capable of being moved close up to one another or of being separated to
an extent which is governed by the lengths of the connecting links. One of the
bars is secured to the underside of the lathe top.
In one form of guard the second bar is capable of being extended or separated
from the first until it projects over the shuttle race. In another form the second bar
is placed much nearer the first and the ends of the links project beyond it and over
the race when the guard is in its operative position. In this case the second bar is
only used for moving the links in and out of position, and of course, a greater
number of links will be necessary.
Springs or the like, combined with stops, may if desired, be employed to normally
bold the guard in its safety position.

COMPLETE SPECIFICATION.
A New or Improved Shuttle Guard for Looms.
We, GEORGE BATEMAN, of 57 Prussia Street, Oldham Road, Power Loom
Overlooker, and HENRY SMITH of 24 Pitt Street, Ancoats, Maker-up, both in
Manchester 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 shuttle guards for looms, and its object is to provide a
guard which shall be effective in action and which shall be cheap and simple in its
construction and application.

page_text: They are capable of being moved close up to one another or of being separated to
an extent which is governed by the lengths of the connecting links. One of the
bars is secured to the underside of the lathe top.
In one form of the guard, the second bar is capable of being extended or separated
from the first until it projects over the shuttle race. In another form, the second
bar is placed much nearer the first, and the ends of the links project beyond it and
over the shuttle race when the guard is in its operative position. In this case the
second bar is used only for moving the links in and out of position, and, of course,
a greater number of links will be necessary.
Springs or the like, combined with stops, may, if desired, be employed to normally
hold the guard in its safety or any other position.
Our improved shuttle guard is illustrated by the accompanying drawings which
we will now describe.
Figure is a partial plan, parts of the lathe top and of the guard being
represented as having been broken away.
Figures 2 and 3 show a part of the lathe top and guard in elevation, the guard
being supposed to be folded back under the lathe top as shown by Figure 2, and to
he in the working position by Figure 3.
Figures 4 and 5 correspond with Figures 2 and 3, the only difference being that
a modified form of stop is supposed to be used.
Figures 6 and 7 show cross sections representing the guard in and out of action
respectively.
Figure 8 is a partial section of the lathe top, drawn on a larger scale, and showing
the bevelled strip which we may employ to give the guard a downward inclination
as shown by Figures 6 and 7.
L, is the lathe top to the underside of which the guard is secured by screws or
otherwise. The guard itself cousists of the two thin parallel bars B, B' connected
together by the links bb which are of equal length and are pinned to the bars in
such a manner as to permit them to be folded freely. The bar B is preferably
bevelled or is provided with bevelled packing pieces so as to throw the guard
downwards. As indicated by Figures 1, 3, 5, and 6, the guard is in its operative
position, the bar B being over the shuttle race and in a position to deflect down-
wards a shuttle flying up through the warp or tending to do so. As shown by
Figures 2, 4, and 7, the guard is folded under the lathe top, as will be required, to
perinit the weaver to piece up broken euds. If made with moderately tight joints
between the links and bars, the guard may be used without any accessories, but we
prefer to employ devices for holding it in position. Thus, as shown by Figure 1, 2
and 3, we may employ a spring S, attached by one end to the lathe top, and by the
other end to the end of the bar B. The tendency of this spring is to pull the
guard into the folded position. In addition to this spring we may also employ a
vertical bolt or stop A, movable upwards and downwards in the holder C, and
arranged upon the lathe top in such a position that when it drops or is pushed
down, it will come to the side nearer to the spring S, of one of the links. By this
means the spring holds the guard hard against the bolt, and the guard cannot
accidentally close. If however, the bolt be lifted, the spring will pull the guard at
once into the closed position, or sufficiently near that position. It is replaced by
hand.
The spring may be dispensed with by using the clip bolt A¹ as represented by
Figures 4 and 5. This differs in having two legs, one of which is arranged to
come upon each side of one of the links when pushed down. One of these limbs is
preferably formed with an inclined or returned end so that when one of the links is
brought against this end the bolt is lifted, and finally drops into the locking position.
In this case the opening and folding of the guard may both be completely effected
by hand.
It is generally advantageous to give the guard a slight downward inclination
towards the front of the loom as shown by Figure 6, so as to bring it closer to its
work.

page_text: In the alternative construction illustrated by plan Figure 9, chiefly applicable
for large looms, the links are arranged much more closely together, and project over
the shuttle race beyond the bar B1, which in this case may act only as a connecting
rod to ensure uniformity of movement of the links. The links are in this case
arranged so closely that a shuttle cannot rise between them should it happen to fly
from the race. In this case also, we may or may not use an additional bar along
the ends of the links.
If desired the bar B may be dispensed with and the inner ends of the links may
be secured directly to the lathe top.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
Shuttle guards for looms, constructed and arranged substantially as hereinbefore
described and as illustrated by the accompanying drawings.
