I, SAMUEL LUCAS, The Hall, Dronfield, in the County of Derby Manufacturer, do
hereby declare the nature of my said invention for IMPROVEMENTS IN SPINNING AND
TWISTING SPINDLES to be as follows:
:-
My invention of improvements in Spinning and Twisting Spindles has for its object
to render such spindles more durable, and it refers particularly to that part of the
spindle upon which the flyer is screwed.
It is usual to make the top end of the spindle with a screw thread upon it, the
diameter of the screwed part being less than the "traverse" of the spindle, thus a
shoulder is formed upon which the flyer bears when it is screwed down to its
position.
As it is not convenient to harden the said shoulder, it follows that as a result of
repeated unscrewing and screwing on, of the hardened flyer against the shoulder, it
becomes crushed and out of shape, and when thus worn down, the flyer is often
difficult to remove.
My invention consists in lowering the position of the shoulder upon the spindle
(say for example a quarter of an inch) and upon this small end I. fit a collar of
hardened and tempered steel, preferably of the same diameter as the spindle Traverse,
and quarter of an inch long (for example) thus bringing the shoulder to its usual or
normal position.
I
My invention is applicable to existing spindles, and will thus render them at that
point as good as new, and more durable.
I do not bind myself to make the collars of hardened steel, although I consider it
the most suitable material.

page_text: I SAMUEL LUCAS The Hall, Dronfield, in the County of Derby Manufacturer, 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:—
My invention of improvements in spinning and twisting spindles has for its object
to render such Spindles much more durable, and it refers particularly to that part of
the spindle upon which the flyer is screwed."
And so that my invention may readily be seen and understood I annex a sheet of
drawings illustrating same.
· Fig. 1, represents a Spindle provided with my improvement-a steel collar for the
flyer to screw up against.
Fig. 2, represents the collar.
"
It is usual to make the top end of the spindle A, with a screw thread B, upon it,
and as the screwed portion is of less diameter than the " traverse or body of the
spindle, a shoulder is formed, upon which the flyer bears when it is screwed down to
its position.
As it is not convenient to harden the said shoulder, it consequently follows that after
the flyer has been repeatedly screwed upon and removed from the spindle, the
pressure
of the hardened flyer against the softer shoulder causes it to wear and get out of
shape, and when thus worn, it is untrue, and the flyer is often difficult to remove.
My invention is carried into effect by lowering the position of the shoulder C. upon
the traverse or body (say for example quarter of an inch) and against the new shoulder
I fit a collar D preferably of hardened and tempered steel, but it may be of other
suitably hard metal if desired, of the diameter of the spindle or thereabouts, and deep
enough to bring the flyer to its usual position on the spindle.
The collar may be screwed upon the spindle, or it may be secured in its position in
any way that is convenient and practicable; it may also be applied to existing
spindles, and by its adoption they will be rendered more durable than they were
before.
Having now, particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
1. In spinning and twisting Spindles, the construction of a shoulder for the flyer to
rest against, by means of a hardened collar (such as D) secured upon the spindle by
any suitable means, substantially as described herein, and as illustrated.
2. In spindles for spinning and twisting, the combination with the spindle A, of a
separate collar D, for the purpose specified, and substantially as hereinbefore described
and as illustrated.
