IMPROVEMENTS IN THE CONSTRUCTION OF SPINDLES USED IN BRAIDING MACHINES."
Year: 1880

page_text: LETTERS PATENT to James Booth, of Manchester, in the County of Lancaster,
for an Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF SPINDLES
USED IN BRAIDING MACHINES."
PROVISIONAL SPECIFICATION left by the said James Booth at the Office
of the Commissioners of Patents on the 11th March 1880.
JAMES BOOTH, of Manchester, in the County of Lancaster. "IMPROVEMENTS IN
THE CONSTRUCTION OF SPINDLES USED IN BRAIDING MACHINES."
My Invention relates to the construction of the spindles used in braiding
machines employed either for making round. or flat braid or for covering cords,
the object of the Invention being to simplify the construction and to facilitate the
threading and general working of the spindles.
In the first place I make the flyer of a piece of wire having a "curl" about the
centre opposite the bobbin and a similar "curl" at the top, so that no threading.
is required for the flyer.
The top of the barrel I make with a transverse opening through from front to
back, and the "drop" I make of a small casting so formed as to slide up and down
outside the barrel.
The "drop" has a projection which catches into the notches in the top of the
bobbin, and a hole is drilled through it in the same direction as the opening
through the top of the barrel above referred to.
The upper end of the weight is also made with an eye or loop also in the same
direction, so that when the weight is raised the thread can be drawn through the
barrel, the drop, and the weight at one operation, and all that remains is to draw
up the thread through the vertical hole at the top of the barrel.
Thus there are only two "threadings" requisite instead of five as in the ordinary
braiding spindle, and a great saving in the operative's time is thereby effected.

JAMES BOOTH, of Manchester, in the County of Lancaster. "IMPROVEMENTS IN
THE CONSTRUCTION OF SPINDLES USED IN BRAIDING MACHINES."
My Invention relates to the construction of the spindles used in braiding
machines employed either for making round, square, or other braid or for covering
cords, the object of the Invention being to simplify the construction and to
facilitate the threading and general working of the spindles.
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. 1 in the annexed Drawing is an elevation of a braiding spindle made
according to my Invention; Fig. 2 is a vertical section of the upper end thereof
drawn to a larger scale; and Fig. 3 is an external view of the same partly
turned.
In the first place I make the flyer a, a, of a piece of wire, having a "curl" 6 in s
a convenient situation opposite the bobbin and a similar "curl" c at the top, so
that no threading is required for the flyer, the bottom part a* being a separate
piece and made much stronger than usual in order to hold the curled wire a more
firmly, to be more secure on the barrel, and to give more wear.
The top of the barrel d, d, I make with a transverse opening e, e, through from 2
front to back, and the "drop" f, f, I make of a small casting so formed as to slide
up and down outside the barrel. The "drop" f, f, has a projection g, g, which
catches into the notches in the top of the bobbin, and a hole h, h, is drilled through
it in the same direction as the opening e, e, through the top of the barrel above
referred to.
The upper end of the weight i, i, is also made with an eye or a loop k, k,
(see Fig. 6) also in the same direction, so that when the weight i, i, is raised the
thread can be drawn through the barrel d, d, the drop f, f, and the weight i, i, at
one operation, and all that remains is to draw up the thread through the vertical
hole, l, at the top of the barrel.
Thus there are only two " 'threadings" requisite instead of five as in the
ordinary braiding spindle, and a great saving in the operative's time is thereby
effected.
Fig. 4 is a section of a modification of the same. In this case the hole h in the
drop is made in a vertical direction, so that by raising it and tilting it slightly
forward, as shown in the Drawing, the thread can be passed simultaneously
through the hole h and the wire loop k, k, at the top of the weight, so that in this
case also there are only two threadings.
Fig. 5 shows another modification in which the wire loop k, k, passes up through
the middle of the drop to be threaded, and in this case the threading through the 4
drop is entirely dispensed with. It will be seen that in this case the drop ƒ slides
inside the barrel d, d.
Having now described the nature and object of my said Invention, together with

page_text: the manner in which the same is to be or may be performed or carried into
practical effect, I wish it to be understood that I claim as my Invention,―
The improvements in the construction of the spindles used in braiding machines,
as hereinbefore more particularly described and represented by the Drawings
annexed.
In witness whereof, I, the said James Booth, have hereunto set my hand and
seal, this Ninth day of September, in the year of our Lord One thousand
eight hundred and eighty.
JAMES BOOTH. (L.S.)
