PROVISIONAL SPECIFICATION.
Improvements in the Method of and in Apparatus for Securing
Bobbins in the Shuttles of Looms.
I, ALFRED GIBSON, of 2 Union Street, Batley, in the County of York, Loom
Tuner, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to firmly secure the bobbins upon the pegs of
shuttles without injuring or splitting the same, and so that any of the ordinary
shapes of bobbins will fit and be secured by my improvements I employ a shuttle
peg with a square end near its pivot, and without spring but so fitted into its recess
as to give a little play from top to bottom, but no lateral play.
Above the pivotted part of the peg is a pivotted cap or fastener with a projection
below its pivot, immediately above the pivot of the peg, one end of said pivotted
cap partly encircles the bobbin and the other end is in contact with and is held up
by a spring, preferably a blade, or spiral spring, as required.
Dated this 17th day of April 1894.

COMPLETE SPECIFICATION.
Improvements in the Method of and in Apparatus for Securing
Bobbins in the Shuttles of Looms.
I, ALFRED GIBSON, of 2 Union Street, Batley, in the County of York, Loom
Tuner, 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 firmly secure hobbins upon the pegs of shuttles,
without injuring or splitting the same, and so that any of the ordinary shapes of
bobbins will fit and he secured by my improvements.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a plan of shuttle having wheels or runners, with my improvements
applied thereto.
Fig. 2, is a sectional elevation of Fig. 1.
Fig. 3, is a plan of shuttle without wheels or runners with my improvements
applied thereto.
Fig. 4, is a sectional elevation of Fig. 3.
Fig. 5, is a detail view, showing the front of the pivoted cap or fastener as herein
referred to.
In carrying out my invention I employ a shuttle peg A with a square end Bat
ite pivot C, and without spring, but so fitted into its recess as to give a little play
from top to bottom but no lateral play.
Above the pivoted part of the peg A is a pivoted cap or fastener D with a
projection or boss E below its pivot F, and above the pivot of the peg, one end of
the said pivoted cap or fastener D partly encircles the bobbin G and the other
end is in contact with, and is held up by a. spring H preferably a blade, or spiral

page_text: spring, as required, a blade spring being used in the case of shuttles having wheels
and spiral spring in the case of shuttles without such wheels or
or runners
runners.
On depressing the part K the pivoted cap or fastener D is caused to release the
bobbin G so that it can be withdrawn from off the peg A, and is returned to its
position for gripping the bobbin G by spring H.
The boss E is so constructed that should the bobbin by any accident be released
from under the cap or fastener D, the boss E will come in contact with the peg B
and so prevent the part K from rising up above the shuttle top, thereby preventing
any damage which the part K might do to the warp.
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 I
claim is :-
1. In a loom shuttle, the combination with the bobbin thereof, of a pivoted cap or
fastener, one end of which is adapted for gripping or partly encircling the bobbin,
the other being in contact with a spring by which the said cap or fastener is
caused to have its gripping action upon the bobbin, substantially as set-forth.
.2. In a loom shuttle, the combination of the peg A, pivotted cap or fastener D,
and spring H, substantially as and for the purposes set-forth.
