An Improved Device or Apparatus for Regulating the Operation of
the "Swell to the Shuttles of Looms for Weaving.
"
I, ABRAHAM HOLDSWORTH, of 16, Beck Street, Leeds Road, Bradford, in the
County of York, Weaving Overlooker, do hereby declare the nature of this
invention, to be as follows:-
The device or apparatus, according to my invention, consists of a bracket or
carrier provided with lugs at top and bottom, in which lugs a spring-regulated rod
or spindle works. The rod or spindle has a square continuation at its lower end
(which works through a square hole in the lower lug) terminating, below the lug,
in a flat foot or hammer. The other portion of the rod or spindle is rounded, and
works at top through a round hole in the upper lug, and is kept in its normal
position by means of a spiral spring which surrounds it, one end of such spring
bearing against the inner surface of the upper lug and the other end against the
shoulder formed by the top of the square part of the rod or spindle. Or the rod or
spindle may be kept in position by means of a flat spring, fixed to the outer surface
of the upper lug and bearing against the top end of the rod or spindle. Or I may
employ both the flat and the spiral springs. A slot is made through the upper part
of the metal forming the bracket or carrier to receive a screw threaded bolt and
nut for fastening the device or apparatus on to the going part of the loom, in the
proper position, so as to allow of the foot or hammer of the spring rod resting on
and pressing against the tongue or wing of the stop-rod of the loom.
The apparatus operates as follows:-
-
As soon as the shuttle leaves the shuttle-box the "swell is raised by the action
of the spring on the rod or spindle, thereby depressing the stop-rod, in which
position it remains until the shuttle re-enters the shuttle-box, when the "swell" is
lowered and the stop-rod again raised clear of the frog.

"
I, ABRAHAM HOLDSWORTH, of 16 Beck Street, Leeds Road, Bradford, in the
County of York, Weaving 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:-
The object of this invention is to provide an improved arrangement of spring for
operating the stop rod and swell of weaving looms and in a great measure obviating
the defects of the ordinary spring.
For this purpose I employ a spring-regulated rod or spindle capable of a certain
amount of longitudinal motion and mounted in a bracket or other attachment
secured to the going part of the loom in any convenient manner. One end of this
rod or spindle is arranged to bear against the tongue or other suitable part of the
stop rod so as to operate the stop rod in a somewhat similar manner to the ordinary
spring but without the usual jerky action and with the decided advantage that in
case the spring breaks the stop rod mechanism is not rendered inoperative.
To fully describe my invention reference is made to the accompanying sheet of

page_text: drawings forming a part of this Specification in which similar letters of reference
indicate corresponding parts in each of the figures.
Figure 1, is a front view of one end of such parts of the going part of a weaving
loom as are necessary to illustrate the application of my improvements thereto.
Figure 2, is a cross section of the same on the broken line a, b.
Figure 3, is an elevation on a larger scale of my improved attachment.
The bracket A is secured to the front of the going part B by means of the bolt C
passed through the slot D in the back of the bracket and through the going part.
The spindle E is mounted in bearings in the lugs F, and G formed at the top and
bottom of the bracket The top bearing is formed by an adjustable piece H screwed
into the lug F and provided with a check nut J. The bearing piece H is provided
with a central hole fitting the rounded portion K of the spindle and the bottom of
the spindle L is of square section fitting a square bearing formed in the lower lug G.
A spiral spring M more or less compressed is mounted upon the spindle between
the bottom of the screw-bearing piece H and the shoulder formed by the top of the
square portion L, and the hammer shaped foot N of the spindle bears upon the
tongue O of the stop rod P. The foot N is made hammer shaped to form a broad
bearing upon the tongue O and one side of the hammer preferably projects more
than the other so that in case it is not convenient to place the bracket immediately
over the centre of the tongue the hammer may still bear broadly across it and by
turning the spindle half way round the projecting end of the hammer may be
reversed as shown by the broken lines Figure 3.
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:
A spring spindle mounted upon the going part and adapted to operate the stop
rod, substantially as herein shown and described and illustrated in the accom-
panying drawings.
