This invention relates to the construction of the spindles used in braiding
machines, the object being to prevent the weight' from falling down the spindle
when not required to do so and forming a slack end.
In the ordinary construction of the spindles to which my improvements relate
the flyer is provided with an eye or drop pivotted thereto and falling into the
hollow spindle through an opening cut in the upper part thereof.
At the bottom of this opening is a slight notch into which the said drop fulls
(when allowed to do so by the weight) locking thereinto and into notches cut in
the bobbin.
Formerly however this drop did not always fall straight into the said notch in
the spindle and therefor did not lock the bobbin, and the weight through which
the thread passed was allowed to fall, form a slack end and stop the machine.
My invention consists in forming a deep slot in the spindle instead of the notch
so that the drop never leaves this slot even when the weight is at its highest point
and the bobbin free of the drop, and thus the possibility of the bobbin not being
locked is prevented.
The pivot of the said drop is also fixed much more loosely than hitherto, the
drop being held in its proper groove at the free end, and thus the locking is much
quicker and inore certain than when the pivot was so tightly fixed in the flyer.

WILLIAM ASHTON of Manchester in the County of Lancaster IMPROVEMENTS
IN THE CONSTRUCTION OF SPINDLES USED IN BRAIDING MACHINES
This invention relates to the construction of the Spindles used in braiding-
machines the object being to prevent the weight from falling down the Spindle
when not required to do so and thus forming a slack end. Such being the nature
and object of my said invention I will now proceed to describe in detail the
manner in which the same is to be or may be performed or carried into practical
effect, and in order that the same may be clearly understood I have annexed
hereunto a sheet of drawings illustrative thereof and have marked the same
with figures and letters of reference corresponding with those in the following
explanation thereof.
Fig represents a side view of a braiding spindle and flyer constructed according
to my invention and Fig 2 is a section of the same
Fig 3 is a side view showing a slight modification of the same
In the ordinary construction of the braiding spindles a. a to which my
improvements relate, the flyer b. b. is provided with an eye or drop lever c. c
pivotted thereto and falling into the hollow spindle a. a through an opening d. d.
cut in the upper part thereof
At the bottom of this opening was a slight notch into which the said drop
lever c. c. fell (when allowed to do so by the weight e. e) locking thereinto and
into the notches cut in the head of the bobbin f. f.
Formerly however this drop lever c. c. did not always fall straight into the said
notch in the Spindle and therefore did not lock the bobbin f. f. and the weight e. e
through the eye of which the thread passed was allowed to full so as to form a
slack end and thus stop the machine unnecessarily
My invention consists principally in forming a deep slot at g. g in the Spindle
(instead of the shallow notch hitherto made) so that the drop-lever c. c never
leaves this slot even when the weight e. e. is at its highest point (as shewn at
Figs 1 and 2) and the bobbin quite free of the drop-lever c. c. and thus the
possibility of the bobbin f. f. not being locked is prevented
The pivot of the said drop-lever c. c may be fixed much more loosely, than
hitherto the drop-lever being held in its proper groove at the free end and thus
the locking is much quicker and more certain than when the pivot was tightly
fixed in the flyer b. b.
Instead of making the slots in the sides of the barrel of the Spindle for passing
the thread through the eye of the weight as shewn at Fig 1. I sometimes
dispense with these side slots and I make a slot in the front of the Spindle as
shewn at i. i in Fig 2 and I then turn the weight e. e one quarter round so that
it can be threaded from the front. The Spindle thus having only one slot opposite
to the deep notch is stronger than if it had two at the sides as at Fig 1
As a modification also I sometimes cut off the top part of the flyer and form the
drop-lever like a bell crank as shown at Fig 3 which gives a more even tension to
the thread and causes it to fall into the notch with greater certainty. In this
case the thread must be passed through an eye at k. k. to prevent it from getting
into the joint.
Having now described the nature and object of my said invention together with
the manner in which the same is to be or may be carried into practical effect

page_text: I would remark in conclusion that I claim as my invention the improvements in
the construction of braiding Spindles as herein before particularly described and
illustrated by the drawing annexed. In witness whereof I the said William
Ashton have hereunto set my hand and seal this twenty ninth day of February
5 in the year of our Lord 1884
