I ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Engineer do hereby declare the nature of this invention for "IMPROVEMENTS IN
SHUTTLES (a communication from John P. Thompson of Fall River, county of
Bristol, United States of America) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to a new and useful improvement on loom shuttles having
for its object to obviate the injurious practice common among loom operators of
putting the lips to the side of the shuttle for the purpose of sucking the ends of
the thread or "filling" through. To this end this improvement consists in the
improved construction and combination of parts which will be hereinafter more
fully described:
On the accompanying Drawing,
Figure 1 represents a top or plan view of one end of the loom shuttle in which
the improvement is embodied.
Figure 2 represents a perspective front view of the same.
Figure 3 is a perspective rear view.
Figure 4 is a cross section through the broken line X, X in Figure 1.
Figure 5 is a side view of one end of the shuttle; and,
Figure 6 is a perspective detail view of the adjustable eye piece which forms a
part of the invention.
Similar letters of reference indicate corresponding parts in all the figures.
On the Figures in these Drawings A indicates the body proper of the shuttle
and A¹ the. end of the same-B represents the metallic eye piece which is shown
in detail in Figure 6 of the Drawing and which is provided with an exterior screw
thread B¹ and has its hollow end recessed or cut away spirally for the purpose
hereinafter specified-This metallic eyepiece is inserted transversely through that
end of the shuttle which is shown in the Drawings the said end being provided
with a curved or V shaped slot c which leads or opens from the main recess in the
shuttle to the space in which the recessed end of the eye piece B is located,

D denotes a spirally curved guide which is of the shape shown in the Drawing
and is secured by one of its ends in the side of the end A¹ of the shuttle body
immediately opposite to the hollow. end of the eyepiece B; the free end of the said
guide being normally in or a little below the game horizontal plane as the free end
of the jaw on the hollow end of the eye piece which said jaw is formed by the
cutting of the spiral slot.
In the end of the V-shaped slot c which communicates with the main recess of
the shuttle is secured the wire hook or guide F which serves to prevent the
filling" from flying out of place before it enters the curved slot and eyepiece.
The manner in which the eye-piece is threaded is as follows:-
The operator first slips the free end of the "filling" down from the upper side
into the wire book or guide F and then draws it around through the curved slot C
when by making a circular motion of the hand which holds the free end of the
filling in the direction indicated by the arrow in Figure 5 of the drawing the
filling" following the spiral guide D will enter the hollow end of the eye piece
through the spiral slot in the end of the same thereby threading the shuttle.
И
For the purpose of increasing the tension the screw threaded eye piece is turned
by means of a screw driver inserted into a notch G in one end of the eye piece on
that side of the shuttle which is opposite to that on which the thread emerges
from the shuttle so that the thread or "filling" will thereby be wound around the
cylindrical body of the eye piece whereby the tension is increased to any desired
extent.
It will be seen that these improvements are of such a nature as not to materially
increase the cost of the shuttle and that they can be applied to shuttles of different
kinds by very slight modifications in the construction of the same,
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated
to me I declare that what I claim is
1. As an improvement in loom shuttles, the adjustable eye piece provided with
a spiral slot at its hollow end for the admission of the thread or "filling" into the
said eye piece, substantially as and for the purpose set forth.
2. The combination with the loom shuttle body having the V-shaped slot c, of
the adjustable eye piece B provided with a spiral slot at its hollow end for the
admission of the thread or "
filling" into the said eye piece, substantially as and
for the purpose set forth.
8. The combination of the loom shuttle body provided with a V-shaped slot c,
the spiral guide D, and the adjustable eye piece B provided with a spiral slot at its
hollow end for the admission of the thread or "filling" into the said eye piece,
substantially as and for the purpose set forth.
4. The combination of the loom shuttle body provided with a V-shaped slot c,
the hook or guide F, and the adjustable eye piece B provided with a spiral slot at
its hollow end for the admission of the thread or "filling" into the said eye piece,
and the spiral guide D, all constructed and combined to operate substantially in the
manner and for the purpose shown and specified.
