Improvements in Spindles for Braid Plaiting Machines.
I JAMES BOOTH of Brownsfield Mills, Great Ancoats, Manchester, Machinist,
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 improvements refer to the spindles of braid plaiting machines, whereby the
drop action is rendered more positive than heretofore and the threading of the
spindle is facilitated..
The accompanying drawing shews my improved spindle, in which
Fig. 1 is a side view and Fig. 2 a back or rear view.
(A) is the barrel of the spindle which in my invention is shortened and stopped
off at, or about, the base of bobbin (B). A rectangular bar (C) extends upwards
and fills the place of the heretofore extended barrel.
This bobbin (B) is carried in the usual manner upon a stud (D) and provided
with a "drop" (E) taking into notches (F) in the bobbin (B) in the well known
manner, , but according to my invention the drop (E).extends through an opening (G)
in the rectangular bar (C) and is provided with an eye (H) at its extremity,
nearly in line with an eye (J) formed in a projection (J) extending from the
rectangular bar (C). An eye (K) is also formed in a lateral extension of the
bar at (L), whilst the top of the bar is formed as shown with an eye (M) concentric
with the barrel (A).
In threading up this my improved spindle the yarn is led from the bobbin (B)
through the eye (K), upwards and through the eye (J), thence through the eye (H)
in the drop (E), downwards through the wire loop (M¹) upon which hangs the
drop rod (N) for imparting tension to the yarn, and finally upwards and out
through the main centre eye (M).
The action of this my improved spindle will be readily understood by those
conversant with braid plaiting machines, and particularly that the drop (E) is held
down by the tension on the yarn until the wire loop (M) of the rod (N) rises to
such a point as to come in contact with the drop (E) when both drop rod (N) and
drop (E) rise together until the unlocking of the bobbin has been accomplished
and the required amount of slack yarn obtained when the "drop" falls and
engages with the notches (F) with certainty.
The advantages arising from this arrangement of parts are 1st:-The drop
action is rendered more certain by reason of the yarn, under the weight of the
drop rod, tending to pull it into contact with the notches (F) in the bobbin, and
so prevent it unlocking except at the proper time as hereinbefore described, and
2udly-The threading up of the spindle is simplified and the parts are more
accessible for cleaning and the eye (K) in the lateral extension (L) being tangential
to the bobbin allows the yarn to unwind with greater freedom and less friction.
As a further feature of my invention, and particularly as applied to spindles of
the larger type, I may provide the drop rod (N) with a flange to prevent dirt or
other objectionable matter getting into the spindle barrel.
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
The improved braid plaiting spindle, consisting essentially of the shortened

page_text: barrel (A), extension piece (C) with "eyes" formed therein, slotted opening (G)
and drop (E) all mounted and operating substantially as and for the purposes set
forth.
