IMPROVEMENTS IN BOX END SPRINGS USED IN LOOMS FOR WEAVING
Year: 1884

SAMUEL Cook, Machine and Spring Maker Bury, Lancashire JOHN FEILDEN,
Loom Overlooker, Brown Street, Bury, Lancashire. We do hereby declare the
nature of our Invention for IMPROVEMENTS IN BOX END SPRINGS USED IN
LOOMS FOR WEAVING to be as follows:—
The object of our improvements is to lessen the cost of box and springs and to
make them more durable than the ordinary springs hitherto in use. It is well
understood that the "fly spindle" of the power loom, on which the "picker" works
is held firmly in position at one end by a steel spring fixed on the outside end of
the "shuttle box." This spring has a countersink or indent struck into its surface
to receive the end of the spindle and keep it in its place when the loom is working.
This indent soon gets worn through, or out of shape from the high speed at which
the loom is driven and has to be replaced with an entirely new spring; to remedy
this evil we affix to the ordinary spring, a revolving disc or segment moving on a
fixed centre which has a number of indents on the outer edge of the circle and by
the above method we are able to bring a fresh indent into use when required
without destroying the spring, the disc or segment can be replaced at a small cost
thereby saving both time and cost.

and JOHN FIELDEN, Loom Overlooker, Brown St., Bury, in the County of
Iancaster. We do hereby declare the nature of our Invention for IMPROVEMENTS
IN BOX END SPRINGS USED IN LOOMS FOR WEAVING 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 our improvement is to lessen the cost of box-end springs and to
make them more durable than the ordinary springs hitherto in use.
<<
It is well understood that the "fly spindle" of the power loom on which the
'picker" works, is held firmly in position, at one end, by a steel spring, fixed on the
outside end of the shuttle box. The spring has a "countersink or indent struck
into its surface to receive the end of the spindle and keep it in its place.
This indent soon gets worn through or out of shape from the high speed at which
the loom is driven and has to be replaced with an entirely new spring, to remedy
this evil we affix to the ordinary spring a revolving disc or segment, moving on a
fixed centre which has one or more indents on the outer edge of the circle, segment
or fitting bit; and by the above method we are able to bring a fresh indent into
use when required without destroying the spring, the disc, segment, or fitting bit,
can be replaced at a small cost, thereby saving both time and expense.
And in order that our Invention may be fully understood and readily carried
into effect, we proceed to describe the accompanying Sheet of Drawings, reference
being had to the Figures and letters marked thereon.
In carrying out our improvement we take a flat spring, of the ordinary
construction, with the exception of a slight modification of shape at the top (Fig. 1,)
and, instead of a depression to receive the spindle end we punch a round hole
through the body of the spring for the purpose hereafter described. We provide
a loose steel fitting bit, or disc having one or more indents round the outer edge, or
circumference to receive the end of the fly spindle, we then attach the two, together,
by loosely riveting the same through the body of the spring, and when the fitting
bit is moved to the centre of the spring, the convex protruberance at the back drops
into the round hole (A) in the body of the spring, & is then in position ready for
use, and when one indent is worn through or out of shape, another can be brought
into use, by simply turning the next indent of the segment or disc to the central
position or as shewn at (Fig. 5) a new fitting bit can be put in position without
removing or damaging the spring.
This will be clearly understood by reference to the Figures and letters of the
accompanying Sheet of Drawings. (Fig. 1) is a front view of the spring made out
of sheet steel, prepared to receive the disc, or segment, or fitting bit, through
the top part of this spring we punch a round hole (A) sufficiently large to receive
the convex protruberance formed by the indent at the back of the fitting bit or
segment which holds or supports the end of the fly spindle when working. (B) is
a rivet hole for attaching the segment or fitting bit to the body of the spring.
Fig. 2) is a loose bit or segment having three or more hollows or indents c, c, c,
struck into its surface, to receive the spindle end and a small hole (B) through
which, and a corresponding hole through the body of the spring, a rivet joins the
two together.
(Fig. 3) is a disc affixed in the same manner and for the same purpose.
(Fig. 4) is an edge view with the fitting hit or disc attached by the rivet (Bland

page_text: (Fig. 5) is another form of the fitting bit, passing through a slot in the body of
the spring which is cranked to receive the same, and attached by a rivet at the
lower end for the same purpose.
(Fig. 6) is an edge view of the same.
In each of the above cases it is obvious, when one indent is worn through, a
second can very readily be brought into position, or a new fitting bit as shewn at
(Fig. 5) without removing or injuring the spring and when all the fitting bits are
worn through, the spring can be supplied with new bits at a trifling cost, and the
spring remains undisturbed.
Having now described the nature and object of our said Invention, and the
manner in which the same is to be performed, we desire it to be understood, that
what we consider novel, and original and useful and therefore claim as our
Invention is,
Separate or loose fitting bits of the various forms or shapes described for the
purpose of supporting the end of the fly spindle and attached by a rivet or pin to
the box-end springs of power looms at the outer end of the shuttle box..
