An Improved Shuttle Guard.
CORNELIUS MARSHALL 66 Wigan Road Bolton Lancashire do hereby declare
the nature of this invention to be as follows:-
By means of two brackets, one fixed on each end of the sley cap I carry a wire
guard which is bent to a suitable shape. The bracket on the left hand is a simple
bracket through which one end of the guard is projected, on which I place a small
spriral spring, one end of which I screw to the sley cap, and the other end presses
with an outward thrust against the guard, and holds it in the right position during
the time the loom is in operation. The other bracket on the right hand side of
the sley cap has on it a convex shaped projection against which a bent part of the
guard is pressed by means of a spring which has a lateral thrust. When the loom
is set in motion the guard automatically assumes the right position, and is there
held by the spiral spring which has an outward thrust. When the loom is stopped,
and the guard is pressed back, the second spring with the lateral thrust presses the
guard against the convex projection of the right hand bracket, and holds the guard
in the back position against the reed.
I also work this in a completely automatic manner by taking a cord from the
bent part of the guard which is on the right hand side, which cord I attach to
an lever which is fixed on the sley sword close to the swing rail, and this lever
is actuated from a simple lever connected with the setting on rod. The spiral
spring which in the semi-automatic arrangement above described I now reverse
giving to it an inward thrust towards the reed. When the loom is started and the
setting on rod is pushed into position the guard is forcibly pulled into position;
and when the setting on rod is knocked off, the guard is liberated, and the spiral
spring with the inward thrust pushes the guard against the reed.

CUM DEI DI DUITIVATION.
An Improved Shuttle Guard.
CORNELIUS MARSHALL Rose Cottage 66 Wigan Road Bolton Lancashire
Weaving Manager 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 :-
manner.
To the sley cap A Fig. 1 I affix three brackets D H I by means of which I
carry the guard B. The bracket D is of a special construction having a projection P
as shown in Fig. 4, against which the bend E of the guard is pulled by the lateral
thrust of the spring F. The operation of the guard is effected in the following
When the guard B is pressed back underneath the sley cap it assumes
the position as shown at K Fig. 3, and the spring F holds the guard in this position
by means of the bend E binding against the projection P until the loom is
restarted. When the loom is restarted the guard is automatically thrown into its
original position by the momentum of the loom, the bend of the guard E sliding
along the face of the projection P until it is pulled by the lateral thrust of the
spring F into the recess which is formed at the base of the projection P, and
resting against the bracket is firmly held during the operation of the loom.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what I
claim is:
The method of operating the guard B by means of the adjustable spiral spring F,
and the bracket D Fig. 4. which bracket has a projection P which holds the
guard B in position when it is pressed underneath the sley cap A, and which has
formed at its base a recess into which the bent part E of the guard B is pulled
when the guard is thrown into its original position by the momentum of
the loom.
