PROVISIONAL SPECIFICATION.
Improvements in Shuttle Guards for Weaving Looms.
I, SAMUEL THOMAS WHEATER, of 73, Copthorne Street, Horton Road,
Bradford, in the County of York, Mechanic, do hereby declare the nature of this
invention to be as follows:-
This invention relates to Improvements in Shuttle Guards for Weaving Looms,
and its object is to provide a cheap and efficient guard.
For this purpose I employ a metal rod to form the guard pivoted by two or more
arms to brackets or their equivalent secured to the hand rail. A pin or detent is
provided on one or more of the said arms to engage a notch or its equivalent on
the bracket supporting it. This pin or detent is adapted to hold the guard in its
normal or working position but the parts are so arranged that the guard may be
moved bodily in a longitudinal direction to release said pin or detent and leave the
guard free to be either turned up against the hand rail or back underneath it.
When the loom is re-started the motion of the going part causes the guard to
swing back to its normal position and a spring is provided to impart the return
longitudinal motion to the rod to enable the detent or detents to again engage the
notch or notches.
It is obvious that the said pins or detents may be formed on the brackets and
the notches in the arms.
The length of the said arins may be made adjustable to regulate the position of
the guard.

Improvements in Shuttle Guards for Weaving Looms.
I, SAMUEL THOMAS WHEATER, of 73, Copthorne Street, Horton Road,
Bradford, in the County of York, Mechanic, 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 for Weaving Looms,
and its object is to provide a cheap and efficient guard.
For this purpose I employ a metal rod or other suitable rod to form the guard
pivoted by two or more arms to brackets or their equivalent secured to the "hand
rail. A pin or detent is provided on one or more of the said arms to engage a
notch or its equivalent on the bracket supporting it. This pin or detent is adapted
to hold the guard in its normal working position but the parts are so arranged that
the guard may be moved bodily in a longitudinal direction to release said pin or
detent and leave the guard free to be either turned up against the hand rail or back
underneath it. When the loom is restarted the motion of the going part causes
the guard to swing back to its normal working position and a spring is provided to
impart the return longitudinal motion to the rod to enable the detent or detents to
again engage the notch or notches.
Reference is to be had to the accompanying sheet of drawings forming a part
of this Specification, in which similar letters of reference indicate corresponding
parts in each of the figures.

page_text: Figure 1, represents a plan view of the hand rail of the going part of a loom
with my improved guard applied thereto.
Figure 2, represents a front view of the same also showing the reed and a portion
of the "lay."
Figure 3, represents an end view on a larger scale of Figure 2 without the reed
and lay.
Figure 4, represents a section of the same on the line y, z.
Figure 5, represents a side view of Figure 4 looking towards the right hand
side.
The rod A forming the guard has an L shaped piece a riveted close to each end
and the projecting arms of these L shaped pieces are bolted to the arms B and B₁
pivoted to the brackets C and C₁ secured to the hand rail D. In wide looms
an piece a may also be secured to the middle of the rod to form a central
projection which is also bolted to an arm B2 pivoted to a central bracket C³. The
arms B, B and B2 each have a projection F on the side next to the brackets
adapted to engage notches G in the brackets and hold the guard in the working
position shown in the drawings. But by slightly moving the guard longitudinally
from left to right (and it will be seen the pivots H of the said arms are constructed
to allow this movement) the projections F are disengaged from the notches G
and the guard is free to be moved to either close under the hand rail, as shown by
the broken lines A' Figure 3, or be turned over on the top as shown by the broken
lines A in the same figure. A spiral spring J is mounted upon the pivot H of the
arm B and is compressed between the washer K (secured to the end of this pivot)
and the side of the bracket B with sufficient pressure to keep the rod in the
position shown at A' Figure 3 whilst the loom is stationary and also when the loom
is started (and the rod swings automatically again to its working position as usual)
to move the rod longitudinally as soon as the projections F reach the notches G so
that they again engage and hold the rod in position.
It is obvious that the said pins or detents may be formed on the brackets and the
notches in the arms.
To enable the position of the rod in relation to the lay M Figure 2 to be
regulated, the piece a, a and a are made with slots through which the bolts e
securing them to the arms are passed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
A shuttle guard arranged to be moved longitudinally preparatory to its being
moved out of its working position and adapted to be returned to its working
position by its own inertia when the loom is restarted and held in that position by
a projection or detent F retained in a notch G by a spring J, substantially as
herein shown and described.
