An Improved Shuttle-guard for Looms.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of this invention to be as follows:
This invention relates to an improved shuttle-guard for looms.
The object of the said invention is to construct a shuttle-guard which, while
preventing the flying of the shuttle during its passage from one box to the other,
will leave the warp threads and healds easily accessible either when the shed of the
warp is closed or when the loom is stopped in any position of the lay.
In carrying this invention into practice I secure to the lay-cap a bracket in which
a bell-crank lever is pivoted, whose oscillatory movement about its axis may be
limited by a pin.
One of the arms of the bell-crank lever carries at its extremity a rod or bar
extending over the entire width of the loom and which, when it is lowered, encloses
the shuttle in a kind of duct which it can scarcely leave.
A spring attached to the upper extremity of the second arm of the bell-crauk
lever, and to a point of said bracket, tends to keep the rod or bar always lowered.
The upper extremity of this second arm is also attached, by means of two flexible
or rigid connections arranged in any suitable manner, on the one hand to a fixed.
point of the frame of the loom, and on the other land to the fork for disengaging
the fixed driving pulley, or to the brake or other stopping apparatus.
Thus the bell-crank lever is caused to pass from the position in which the guard
is lowered and in action to that in which the guard is raised and out of action;
either after each throw of the shuttle at the moment the lay has arrived at the end
of its oscillatory movement to one side, or when the loom stops for some reason or
other in any position owing to the disengagement of the fixed pulley from the
brake or the like.

An Improved Shuttle-guard for Looms.
1, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent.
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 an improved shuttle-guard for looms.
The object of the said invention is to construct a shuttle-guard which, while

page_text: preventing the flying of the shuttle during its passage from one box to the other
will leave the warp threads and healds easily accessible either when the shed of the
warp is closed or when the loom is stopped in any position of the lay.
In the accompanying drawing
Figure shows the application of the shuttle guard to a loom having a movable
reed, the said guard being in the position it occupies when it is lowered and in
action and the shed of the warp being open, and
Figure 2 is a similar view showing the position of the shuttle guard at the
moment when the shed of the warp is closed, the shuttle having entered one of the
boxes designed to receive it, and the lay being at the end of its oscillation to
the right.
Similar letters of reference indicate corresponding parts in both the figures of
the drawing.
A A are the warp threads; B the reed; C the lay cap; D the shuttle race.
In carrying my invention into practice I secure to the lay cap C, brackets E in
which levers FG are pivoted in such a manner that their oscillation about the
axis H may be limited by the pin 1.
The levers G carry at their extremities one or more rods or bars K extending
over the entire width of the loom and which, when it is lowered, that is to say, in
the position, shown in Figure 1 encloses the shuttle in a kind of duct which it
cannot leave.
A spring L attached at one end to the upper extremity of the lever F and at the
other end to a point or hook on the said bracket E, tends to keep the rod or bar K
in its lowered position as shown in Figure 1. The upper extremity of this lever F
is also attached, by means of two flexible or rigid connections M N arranged in any
suitable manner, on the one hand to a fixed point of the frame of the loom, and on
the other hand to the fork for disengaging the fixed driving pulley, or to the brake
or other stopping apparatus.
Thus the levers F G are caused to pass from the position shown in Figure 1 in
which the guard is lowered and in action to that shown in Figure 2, in which the
guard is raised and out of action, either after each throw of the shuttle at the
moment the lay has arrived at the end of its oscillatory movement to one side, or when
the lcom stops for some reason or other in any position owing to the disengagement
of the fixed pulley or the brake or the like.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, 1 declare that what I claim is :-
First. A shuttle-guard characterized by the employment of one or more rods
parallel to the width of the loom and extending over this entire width, carried by
levers pivoted upon supports mounted upon the cap of the lay, a rigid or flexible
connection between the lever mounted in the brackets attached to the lay cap, and
the disengaging fork or other part effecting the stoppage of the loom so that this
stoppage produces a displacement of the lower extremity of the oscillating rod
having the effect of completely raising the shuttle guard.
Second. A shuttle guard characterized by the employment of one or several rods
parallel to the width of the loom, carried by levers pivoted upon a support mounted
on the cap of the lay, these levers being kept lowered in proximity to the warp
threads by a spring, and being raised by overcoming the action of the spring when
the lay arrives at the extremity of its oscillation or when the loom is stopped by a
disengaging or other mechanism.
