JOSEPH UNWIN INGHAM, 261, Rochdale Road, Bury, Lancashire, Mill Manager,
do hereby declare the nature of this invention to be as follows:-
My improvement consist of a box end spring which is used to keep the spindle
of the shuttle box in position. The spring will be reversible by cutting the slot
in the spring three fourths of its length and lapping it at both ends thereby
enabling it to be used oftener than hitherto. And it will also by the lapping of
the spring at both ends obviate the necessity of packing underneath the spring
as the spindle gets shorter.

An Improved Shuttle Box Ead Spring for Loo ns for Weaving Calico
or other Textile Fabrics.
I, JOSEPII UNWIN INGHAM, of 261, Rochdale Road, Bury, in the County of
Lancaster, Mill Manager, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
My invention consists of an improvement or improvements in the springs
which are used at the outer end of the shuttle boxes of looms for weaving to keep
the spindle of the shuttle-box (upon which the "picker" runs) in position.
The nature of my said invention and the manner in which the same is to be
performed will be readily understood on reference to the drawings hereunto
annexed, and the following explanation thereof.
Fig. 1 is a face view, and Fig. 2 an edge view of a shuttle box-end spring as
usually employed, a being the body of the spring, the bolt hole for attaching
the same to the shuttle box, e the upper end of the spring which is made narrower
and lapped over, and d a recess or cup formed in this lapped end to receive the
end of the picker spindle.
Figs. 3 and 4 on the drawings are similar views of my improved shuttle box-
end springs. The same letters of reference indicate the corresponding parts.
It will be seen on reference to Figs. 1 and 2 that the ordinary spring is lapped
only at one end, this end being narrow and having only one recess or cup
d

page_text: formed, and hence when this part became worn through, the spring was useless
and had to be thrown away. Another defect was that as the spindle became
shorter, the bolt had to be slacked and a packing placed between the spring
and the shuttle box near the bottom to push the top end of the spring forward.
According to my invention (see Figs. 3 and 4) I make the spring reversible
by lapping it at both ends and I also make it of the same width throughout so
that two or three recesses or cups for the reception of the spindle can be made
at each end and I lengthen the slot or bolt hole to about three quarters, or more,
of the whole length, so that the same spring can be used many times over by
shifting its position whereby a considerable economy is effected; and the lapping
of the spring at both ends will also obviate the necessity of packing underneath
the spring as the spindle gets shorter.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what
I claim is:-
A reversible shuttle-box-end spring for looms for weaving constructed sub-
stantially as herein before described and illustrated by the drawings annexed.
