Improvements in Mechanism for Operating Shuttle Guards of Looms
for Weaving.
We EPHRAIM HINDLE and GEORGE HINDLE, Manufacturers and WILLIAM
ISHERWOOD, Manager all of Bastfield Mills, Blackburn in the County of
Lancaster, do hereby declare the nature of this invention to be as follows:-
This invention relates to further improvements in apparatus for purpose aforesaid
for which Letters Patent No. 10,006 of the year 1890 and Letters Patent No. 7881
of the year 1891 were granted to the present applicants.
According to this our present invention we employ a guard hinged to the slay
cap or hand rail, and by lever or link and pendant rod connect same with one end
of a lever mounted on a fulcrum stud near the bottom of the loom, and at the
opposite end of the said lever is a counterbalance weight. Near the weighted end
of the lever is a slot through which is passed a rod or wire at the lower end of
which is a button, and the upper end of the rod or wire is connected to the ordinary
incline, which operates the brake. The lower end of the before mentioned pendant
rod passes through a hole or slot in the non weighted end of the weighted lever,
and on this rod above the lever is fixed a small collar or button. Above this collar
or button is a second collar to which one end of a leather strap or belt is attached,
the other end of said strap or belt being fixed to the slay bottom or block.
"
or
The action is as follows:-When the loom is in motion, the guard is "on
in its normal state, but at each "beat up" of the slay the leather strap or belt
comes in contact with a stud fixed in the loom frame, and as the slay moves
forward the strap or belt raises the pendant rod and folds the guard close up to
is completed and the slay moves back and the
the slay cap. When the "beat up
strap or belt leaves the stud, the weight of the pendant rod lifts the guard into its
normal or "on" position.
"
When the loom is "knocked off" or stopped the incline and rod or wire allows
the weighted end of the lever to fall, the opposite end is raised and coming in
contact with the collar or button on the pendant rod raises the latter and so folds
the guard close to the slay cap.
When the loom is restarted the incline and rod or wire raises the weighted end
0 of the lever and the weight of the pendant rod again puts the guard on.

Improvements in Mechanism for Operating Shuttle Guards of Looms
for Weaving.
We, EPHRAIM HINDLE and GEORGE HINDLE, Manufacturers, and WILLIAM
ISHERWOOD, Manager, all of Bastfield Mills, Blackburn, 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 further improvements in apparatus for purpose aforesaid,
for which Letters Patent No. 10,006 of the year 1890, and Letters Patent No. 7884
of the year 1891 were granted to the present applicants, the object of the invention
being to prevent the shuttle flying out of the race when the loom is in motion, and
consists of parts so arranged as to be put into operation automatically when starting

page_text: the loom, and to be moved and folded close to the reed cap and out of the way of
the operative when the loom is stopped, and at the "beat up."
Such being the nature and object of our said invention, the following is a
complete description of same, reference being made to the accompanying drawings,
in which :-
Fig. 1. is a front elevation of part of a loom shewing the improved mechanism
for operating the shuttle guard.
Fig. 2 is a sectional end elevation of Fig. 1.
According to this our present invention, we employ a guard 1 hinged or free to
turn in brackets 2 fixed to the slay cap or hand rail 3, and one end of the guard
is, by lever or link 4, and pendant rod 5, connected with one end of a lever 6
mounted on a fulcrum stud 7 fixed to the frame and near the bottom of the loom.
At the opposite end of the said lever 6 is a counterbalance weight 8. Near the
weighted end of the lever 6 is a slot 9, through which is passed a rod or wire 10, at
the lower end of which is-a-button or nut 11, and the upper end of the rod or
wire 10 is connected to the ordinary incline 12 which operates the brake. The
lower end of the before mentioned pendant rod 5 passes through a hole or slot 13
in the non-weighted end of the weighted lever 6 and on this rod 5 above the lever 6,
is fixed a small collar or button 14. Above this collar or button 14 is a second
collar 15, to which one end of a leather strap or belt 16 is attached, the other end
of said strap or belt 16 being fixed to the slay bottom or block 17. In some cases
a spiral spring 18 is attached, one end to the rod 5, and the other end to the ruil 6,
said spring assisting the weighted lever 6, and also ensuring quicker action of the
several parts.
The action is as follows:-When the loom is in motion, the guard 1 is "on" or
in its normal state, but at each "beat up "of the slay, the leather strap or belt 16
comes in contact with a stud 19 fixed in the loom frame, and as the slay moves
forward, the strap or belt 16, raises the pendant rod 5 and folds the guard 1 close
up to the slay cap 3. When the "beat up" is completed, and the slay moves
back, and the strap or belt 16 leaves the stud 19, the weight of the pendant rod 5
and the spring 18 lifts the guard 1 into its normal or on position. When the
loom is knocked off" or stopped, the incline 12 and rod or wire 10 allows the
weighted end of the lever 6 to fall, the opposite end is raised and coming in contact
with the collar or button 14 on the pendant rod 5, raises the latter and so folds the
guard 1 close to the slay cap 3.

"
When the loom is re-started, the incline 12 and rod or wire 10 raises the
weighted end of the lever 6, and the weight of the pendant rod 5 again puts
the guard on.
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 mechanism for operating and controlling the shuttle guard as herein
described and substantially as illustrated by the annexed drawings.
(2.) The guard 1, lever or link 4, pendant rod 5, weighted lever 6, rod or
wire 10, incline 12, strap or belt 16, and stud 19, all in combination as and for
the purpose herein described and substantially as illustrated by the annexed
drawings.
Prated the 7th day of November 1898.
