PROVISIONAL SPECIFICATION.
Improvements in Shuttle Guards of Looms for Weaving.
We, JOHN ATKINSON, of 16 Lawerence Street, Blackburn, in the County of
Lancaster, Wood Turner, and SAMUEL BROGDEN, of 18 Lawerence Street aforesaid,
Overlooker, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in shuttle guards of looms for weaving,
the object being to construct a guard which is automatically put into the active
or on" position as the loom is started, and as soon as the loom is stopped or
"knocked off" the guard is automatically folded close to the reed cap and out of the
way of the weaver. The guard is simple in its construction and efficient in its action
and when in the active position is held rigidly in position in such a manner that
the shuttle cannot possibly fly out.
According to this invention we employ a guard consisting of two or more parallel
rods or bars joined together and hinged to the front of the reed cap. One end of
the guard is by link and universal joint connected to one end of a lever pivoted on
a bracket fixed to the lower part of the shuttle box. Fixed to the lever is a bracket
with a cam or inclined surface and tail piece, said cam surface resting on a stud fixed
to the stop handle.
When the loom is at rest a projecting part of the cam surface rests on the stud in
the stop handle and the guard is "off" or inoperative, but when the handle is moved
to start the loom the stud moves down the incline to the tail piece, the lever falls
and moves the guard to the active or "on" position. The tail piece prevents the
guard rising or being folded to the reed cap as long as the loom is in motion.

We, JOHN ATKINSON, of 16 Lawerence Street, Blackburn, in the County of Lancaster,
Wood Turner, and SAMUEL BROGDEN, of 18 Lawerence Street aforesaid, Overlooker, 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 the
object being to construct a guard which is automatically put into the active position
or "on" when the loom is started, and as the loom is stopped or "knocked off" the
guard is automatically folded close to the reed cap and out of the way of the weaver.

page_text: The guard is simple in its construction and efficient in its action and when in its
active position is held rigidly in such a manner that the shuttle cannot fly out. The
guard is also provided with a simple appliance whereby at each beat up of the slay
the guard is slightly raised so as to clear the temples and rollers, and this allows of
the guard being much nearer the shed than heretofore consequently lessening the-
liability of the shuttle rising in the race.
Such being the nature and object of our said invention, the following is a complete
description of same, reference being had to the accompanying drawings in
which
f
Figure 1 is a front elevation of the shuttle guard in its active position, that is, when
the loom is working.
A
Figure 2 is a similar view to Figure 1 but shewing the guard in its inoperative
position when the loom is stopped.
According to this invention we employ a guard 1 consisting of two or more parallel
rods or bars joined together by bands of metal 2 and hinged at 3. 3 to the reed cap 4.
One end of the guard 1 is by a short link 5 connected to one end of a short shaft or
rod 6 mounted on the reed cap 4, the other end of such shaft 6 being connected by
link 7 to a rocking lever 8 pivoted on the bracket 9 fixed to the lower part of the
front of the shuttle box. Fixed to the lever 8 is a bracket 9" with a cam or inclined
surface 10 and a slot formed by a tail piece 11 said cam surface 10 resting on a stud
12 fixed to the stop handle 13.
Fixed to the rocking lever 8 is a small bracket 14 and anti-friction bowl or runner 15
and at each beat up of the slay the runner 15 comes into contact with a bracket or
projection fixed to the breast rail of the loom and which slightly raises the lever 8
and the guard 1 so that the latter clears the temples and rollers without being
sufficiently raised to allow the shuttle to fly out. The guard will operate equally as
well without the latter device but its employment enables the guard to be brought
much nearer to the shed so preventing any possibility of the shuttle rising.
At 16 is a guide bracket for steadying the lever 8 as it moves up and down, and
this bracket 16 is bolted to the front of the shuttle box.
The Action is as follows: When the loom is at rest a projecting part of the cam
surface 10 rests on the stud 12 in the stop handle 13 and the guard 1 is "off" or
inoperative (see Fig. 2) but when the handle 13 is moved to start the loom the stud 12
moves down the incline 10 to the tail 11, the lever 8 falls and moves the guard to
the active or "on" position (see Fig. 1). The tail piece 11 prevents the guard rising
or being folded to the reed cap 4 as long as the loom is in motion.
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.
(1) The general construction arrangement and combination of parts constituting
the improved shuttle guard as herein described and substantially as illustrated by the
annexed drawings.
(2) A guard 1 which is by connecting links attached to one end of a lever 8 on
which is an inclined or cam surface 10, the stud 12 on the stop handle 13, all in com-
bination as and for the purpose herein described and substantially as illustrated by
the annexed drawings.
