Improvements in Shuttle Guards for Looms.
HERBERT SUTCLIFFE, Hough End, Bramley, near Leeds, in the County of
Yorkshire, Worsted Manufacturer, and Rurus KELLETT, Hough End, Bramley, near
Leeds, in the County of Yorkshire, Worsted Manufacturer, do hereby declare the
nature of this invention to be as follows:-
The object of this Invention is to produce an efficient shuttle guard for a loom,
which shall, when the process of weaving is being carried out, prevent the possibility
of a shuttle flying out of the loom, as is now often the case, where weaving is carried
on without the protection afforded by the use of a shuttle-guard.
In carrying out the object of this Invention, two or more castings of metal are
fixed to the hand-rail of the loom in certain required positions. Through each of
these castings a hole is made in a horizontal direction, and at the upper part of the
Into this first
casting a semi-circular piece is cut away down to the horizontal hole.
set of castings, we fix a second set of two or more castings of metal, each casting
having a stud upon it corresponding in size to the horizontal holes in the castings
that are fixed to the hand-rail; each of these castings has also a projection or button
upon the upper part of the said stud.
The first set of two or more castings are fixed to the hand-rail in the required
positions by means of screws, or in any other suitable manner; the second set of two
or more castings are then put into the first set of castings, by pushing the studs
through the horizontal holes; the projections or buttons on the studs of the second set
of castings fitting into the semi-circular cuts that are in the first set of castings.
A spiral spring of a required length is fixed by one end to the ends of each stud, and
the reverse ends of the spiral springs are fixed to the hand-rail.
A bar of wood or metal, or any other material is then fixed to the lower portions of
the second set of castings, this bar being a required distance away from the warp
that may be put into a loom, and fixed in such a position that it is impossible for a
shuttle, when passing along the shuttle-race from one shuttle box to another, to fly
out between the hand-rail and the said bar.
During the operation of weaving, the said bar is kept in a rigid position by the
spiral springs drawing the studs tightly through the horizontal holes in the castings
fixed to the hand-rail, the projections or buttons upon the studs thus fitting tightly
into the semi-circular cuts, and maintaining the whole of the shuttle guard in a very
firm position.
When a weaver wishes for any reason to get at any portion of the warp that is under
the shuttle-guard, this is done by pushing the bar backwards, when the projections
or buttons on the studs slip from their positions out of the semi-circular cuts in the
castings upon the hand-rail, and the bar moves under the hand-rail. When the loom

its original position, where it remains firmly and rigidly set as described.

Agents for Applicants.
The object of this Invention is to produce an improved Shuttle Guard for
looms.
Figure 1, is a view of one of the first set of castings to be fixed to the hand-rail
of a loom.
Figure 2, is a view of Figure 1. showing the semi-circular cut in the casting.
Figure 3, is a view of one of the second set of castings, with a bar of wood or
metal.:
Figure 4, is a view of Figure 3 showing the projection or button which fits into the
semi-circular cut, in the first set of castings.
Figure 5, is a view of one end of the Shuttle Guard, as fixed to a hand-rail of a
loom, in the open position during the operation of weaving.
Figure 6, is a view of one end of the Shuttle Guard, when pushed back against
the hand-rail, showing the first and second sets of castings out of gear with each
other.
In carrying out the Invention two or more castings B of metal are fixed to the
hand-rail A of a loom, the said castings B, having a horizontal hole b', and a semi-
circular cut b² in them.
A second set of metal castings Care used, each having a stud c¹ and also a projection
or button c² upon it.
The studs c¹, and the projections or buttons c², of the castings C, are put into the
horizontal holes and the semi-circular cuts 62, of the castings B.
To the ends of each of the studs o¹, are fixed the end of a spiral spring D, and the
reverse end of each spiral spring D is fastened to the hand-rail A. by a screw or
staple d'.
A bar of wood or metal E is fixed to the lower ends of the castings C.
During the operation of weaving the shuttle guard is in an open position as in
Figure 5, the shuttle passing backwards and forwards behind the bar E.
When a weaver wishes for any reason to get at any portion of the warp that is
under the shuttle guard, this is done by pushing the bar E backwards, when the
projections or buttons c² on the studs c¹ on the castings C, slip from their positions out
of the semi-circular cuts 62 in the castings B, and the shuttle guard comes to the
closed position as shown in Figure 6.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed, we declare that what we
claim is:-
1. In shuttle guards of looms the employment of the castings B. having each a

page_text: horizontal hole 61, and a semi-circular cut 62 in them; the castings C, each having a
stud c¹ and a projection or button 62 upon them; the spiral spring D; and the bar E;
the whole being put together forming a shuttle guard, and fixed to the hand-rail of a
loom as described.
