An Improved Shuttle Guard for Looms for Weaving.
We, JOHN HENRY SHACKLETON REDMAN of I. K. Redman & Son of
Bridgehouse Mills, Haworth near Keighley, Spinners and Manufacturers, and
JONATHAN HOLMES of Higher Marsh, Haworth Overlooker 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 has for its object the protection of the shuttle, and to prevent
it flying out during the operation of weaving, and at the same time to interfere
as little as possible with the movements of the weaver. To enable us to attain
this object, we carry a rod across the front of the sley, and at such a distance
from the sley and the warp, that it will afford protection to the shuttle during
the operation of weaving. This rod we attach to moveable arms on brackets
fixed to the handrail of the loom, and so arranged that when the loom is running,
the rod will be held in the desired position; but when the loom is at rest, the
arms may be turned inward towards the sley, thus bringing the rod under the
handrail, and leaving the whole of the reed or sley front practically clear for
the weaver. To enable us to move the guard, we have the moveable arms of a
special shape, and inside the bracket we place a small helical spring upon a small
spindle having a suitably shaped head. The form of this moveable arm is such,
that when the guard is in the outward or working position, it is held there firmly,
and a projection upon it enables us by a mere pressure of the finger to bring it
under the handrail, where it is again held with sufficient firmness for the purpose,
but the moment the loom starts running, the vibration will cause it to spring
outward and resume the working position.
And in order that our invention may be understood, we proceed to describe it,
and by reference to the accompanying drawings.
Fig. 1 is a section, and Fig. 2, a plan of our arrangement. A is the handrail of
loom, B the sley, C a bracket attached to the handrail, D the moveable arm,
E a section of the bar or rod before mentioned, running parallel to the sley, F the
pin or spindle on which is placed the helical spring G. From the form of the head
of the moveable arm D as shown in section, it will be seen that the pressure exerted
by the spring G upon F will keep it in position for working, because the centre of
the pin F is somewhat below the centre of the fulcrum upon which the moveable
arm D works. And when pressed inwards, the projection Dª will pass over the
head of the pin F and in like manner keep it in the closed position. The dotted
lines D' shows the moveable arm about midway between the two positions.
The bar which we place across the front of the sley, may be a flat bar as shown,
or rounded on the under side, or by preference we make it of the form approaching
that of a letter L, but without a sharp angle at the bend.
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 :-
1st. The arrangement of the bracket and moveable arm of the form herein
described, and
2nd. The use of the spring and pin or spindle as and for the purpose herein set
forth and described, and
