This invention relates to improvements in the method of nounting or fixing the
picker-spindles of weaving looms and its object is to secure the spindle rigidly in.
position in a ready and simple manner and thereby-prevent any play between the
spindle and its bearings. In the present method of fixing any play is liable to be:--
increased by the constant vibration to a harmful or dangerous extent.
For this purpose we form a tee shaped or other suitable head upon the spindle-
and at the other end we form a screw thread and fit a nut thereon and the spindle
is passed through holes in the spindle stud and end plate of the shuttle box and
secured therein in the same manner as an ordinary bolt.
Instead of using a separate nut a female screw thread may be formed in the
spindle stud or end plate to receive the screwed end of the spindle.
Or a thread may be formed at each end of the spindle and a nut fixed at one or
both ends.

COMPLETE SPECIFICATION.
Improvements in or relating to the Picker Spindles of Weaving
Looms.
We, JOHN BENTLEY, of 53, Carlisle Street, Manningham, in the County of
York, Machine Broker, and GEORGE RAMSDEN, of Market Street Works,
Keighley, in the said County, Machine Maker, 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 :-
This invention relates to improvements in the method of mounting or fixing the
picker spindles of weaving looms and its object is to secure the spindle rigidly in
position in a ready and simple manner and thereby prevent any play between the
spindle and its bearings. In the present method of fixing any play is liable to be
increased by the constant vibration to a harmful or dangerous extent.
For this purpose we form a tee shaped or other suitable head upon the spindle
and at the other end we form a screw thread and fit a nut thereon and the spindle
is passed through holes in the spindle stud and the end plate of the shuttle box and
secured therein in the same manner as an ordinary bolt.
Instead of using a separate nut a female screw thread may be formed in the
spindle stud or end plate to receive the screwed end of the spindle.
Or a thread may be formed at each end of the spindle and a nut fixed at one or
both ends.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification in which similar letters of reference indicate corresponding parts
in each of the figures.

page_text: Figure 1, represents a front elevation of the shuttle box or end of the going part.
illustrating my improved method of mounting the spindle.
Figure 2, represents a plan view of the spindle and spindle stud and also a
sectional view of a portion of the end plate and back of the shuttle box.
Figure 3, represents a separate plan view of the spindle.
Figures 4 and 5 are respectively a sectional plan and front elevation on a larger
scale of the head of the spindle stud.
Figure 6, represents a separate view of the spindle with the spindle stud in
section illustrating a modified method of mounting the spindle.
The spindle A has a screw thread B formed at one end and the other end is bent
at right angles to form a head C. The head D of the spindle stud is cut away leaving
a face E at right angles to the back F of the shuttle box and a semicircular recess G
may be formed in this face to receive the head C. To place the spindle in position
the screwed end B is first passed through the hole H in the stud head D and tuen
through the end plate J. The nut K is then put upon the spindle and adjusted to
tightly fix the spindle and the lock nut L is also preferably tightly screwed on.
In the modification shown in Figure 6 both ends of the spindle are screwed and
the hole H in D is tapped, or formed with a female screw thread, to receive one
end of the spindle and the other end is fitted with a nut and lock nut as before.
Instead of forming a thread in H nuts may be fixed on that end of the spindle but
owing to their size they are somewhat objectionable at that point.
As a further modification the outer end B of the spindle may be formed with a
square or other suitably shaped head instead of the nut K. Of course in this case
the opposite end of the spindle is first passed through the end plate J and then
screwed into the hole H in the stud D.
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. The improved method of fastening picker spindles of weaving looms by
means of a suitably shaped head at one end and a screw thread at the other,
substantially as herein shown and described and illustrated in the accompanying
drawings.
2. The improved method of fastening picker spindles by means of a screw thread
at both ends, one end being screwed into the spindle stud or a nut thereon and the
other end passed through the end plate and secured by a nut, substantially as
herein shown and described and illustrated in the accompanying drawing.
