Improvements in Shuttle Guards of Weaving Looms.
EMANUEL SLATER of 16 Entwistle Place Whit Lane Pendleton in the County
of Lancaster, Loom Tackler do hereby declare the nature of this invention to be
as follows:-
The object of my invention is to provide a cheap and efficient guard to prevent
shuttles flying out and doing injury to weavers and others.
It is adapted to be readily pushed against the handrail out of the way when
required, but to automatically return to its working position when the loom is
started. The guard consists of a metal rod which for narrow looms is bent at oue
end into the form of a crank, but with au extra bend forming a support in the
centre for broad looms. At the other end is securely fastened an arm having a
projecting pivot which rests in an adjustable bracket fastened to the hand-rail, this
bracket having an extended piece on one side, to receive the pressure of the upper
part of the arm when the rod is in its working position, it thus prevents any further
movement of the guard rod in an upward or outward direction, but the rod will
give way easily when pressed from the front. There are two adjustable brackets
fastened to the handrail of loom, one to hold the bent part of the rod, and the
other the pivot of the arm for narrow looms, and an extra one about the centre for
broad looms, these are to hold and carry the rod. The curved part of the arm has
a hole through it into which one end of a coiled spring is inserted, this spring is
held by two adjustable eyes which are screwed into the handrail.
When the guard rod is in its working position it is held there by the spring
pressing the curved part of the arm in a downward direction but when the guard
rod is out of action, the curved part of the arm with spring attached, is carried
over the centre or fulcrum, the spring thus pressing the guard rod against the
hand-rail, the spring being regulated by the adjustable eyes to keep the rod in
that position, so that the momentum of the slay and gravity will cause the rod to
automatically return to its working position when the loom is started.

EMANUEL SLATER 16 Entwistle Place Whit Lane Pendleton in the County of
Lancaster Loom Tackler. I 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 :-
The object of my invention is to provide a cheap and efficient guard to prevent
shuttles flying out and doing injury to weavers and others.

page_text: It is so constructed as to be readily pushed against the handrail when required
and to automatically return to its working position when the loom is started.
In the accompanying illustrations Fig. 1 is a front elevation, Fig. 2, an end
elevation, Fig. 3 an enlarged cross section at A, A, and Fig. 4 an enlarged
cross section at B, B, of my invention, which consists of a cranked metal
rod 1 supported in position by brackets 2, 3, 4, which are fastened to the
handrail 5, the centre bracket 4 being constructed as shewn at Fig. 4, con-
sisting of two thin pieces of metal suitably secured to the handrail 5. The
rod 1 is also bent at 6 so as to govern its outward movement by coming in contact
with a projecting part of bracket 2, but the rod will readily give way when pressed
from the front, at one or both ends of the rod, an adjustable collar 7 is fastened
this collar has a hole through it, into which one end of a spring 8 is inserted, the
spring being held in position by two screweyes 9, 10, fastened into the handrail 5,
the screweye 10 has an opening to allow the spring 8 to be inserted more readily
and is made adjustable for regulating the spring. The object of the spring 8 is to
hold the rod against the handrail when required and also to ensure that the rod
will come out again when the loom is started. To permit the guard rod to come
from the handrail to its working position more easily, the adjustable screweye 10
is carried further away from the handrail, but if the rod comes out too easily the
eye, 10, should be screwed further into the handrail 5.
In place of the collar 7 I may flatten, puncture, and bend one or both ends of
the guard rod 1, and insert an end of a spring 8, in the hole or holes thus made in
the rod, I may also employ three or more brackets all similar to the central
bracket 4 and by so doing I dispense with the brackets 2, 3. When the guardrod
is in its working position, it is held there by the spring pressing the collar 7 in a
-downward direction, but when the guardrod is out of action the hole in the collar 7,
-carries its end of the spring 8 over the centre or fulcrum, thus pressing the rod
against the handrail, the collar being adapted for both purposes, the spring 8 being
regulated to keep the rod in such a position, that the momentum of the slay and
gravity combined, will cause the rod to automatically return to its working position
when the loom is started.
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 1
claim is
1. The novel arrangement and combination of the adjustable collar 7, the
spring 8, the fixed and adjustable screweyes 9, 10, and the central bracket 4 all
used for the purpose of operating and regulating the guard rod 1, as and for the
purposes herein described, and substantially as illustrated by the annexed drawings
Figs. 1, 2, 3, 4.
