Improvements in Spool Carriers for Braiding Machines.
I, EMIL GREEFF, of 21, Augustastrasse, in the City of Barmen, Germany,
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:-
The object of this invention is to provide an improved spool carrier for braiding
machines which as will be seen is simple and inexpensive in its construction,
yet effective in operation and one that nearer perfect in shape than the present
spool carriers by reason of the true method of guiding the weight for spanning
the thread, which in order to be kept clean is closed up in a standard, so that
also coloured yarn may be spent with this spool carrier and also yarn of less
quality thanks to the easy and quick revolving spindle which is obtained by a
new bearing attachment and a contrivance for guiding the thread.
I will describe the invention by reference of the accompanying drawings
wherein
Figure 1 is an elevation of the new spool carrier,
Figure 2 is a vertical view taken at right angle of Figure 1,
Figure 3 is a horizontal section,
Figure 4 shows the bearing arrangement for the spindle.
The spool carrier has a foot a of known shape by which it is travelled on the
trackways of the braiding machine. It carries two vertical standards b, c. The
standard b is made of half circular section as may be seen from Figure 3. To
its top is hinged by a bolt f a clamp e which at its free end is formed to a clasp m
that engages a projection 7 extending from the standard c. As both standards
are at their top ends of some spring like action the clamp e clasps firmly the
standards together but it may be easily removed by bending the standard c
somewhat inwards. Between the standards b, c is located the spindle d which
is adapted to carry a cop of yarn which is fastened to the spindle in any
convenient manner but so that it may be easily replaced by a fresh one.
spindle dis supported by bearings arranged in the clamp e and a lug 61 of the
standard b. From Figure 4 may be understood that these portions are provided
with a groove which opens toward the central middle line of the spindle and
in which are inserted a number of balls that are held in their respective groove
by the overlapping outer and inner edge of the groove. The ends of the spindle
are preferably tapered so as to conveniently engage with the balls by which
arrangement a quick and easy turning of the spindle is obtained.

The
The cop carries at its head a toothed brake i with which temporarily engages
a pawl h by means of a stud 2. The said pawl is hinged to the clamp by
means of a bolt g and is operated by the weight o. The weight is arranged in
the standard c which for this purpose is made hollow and can slide therein up
and down. It is provided with an eye for the thread p. The standard 6 has
a curved wall shaped extension n of metal which partly embraces the cop k and
is provided for a better guidance of the yarn.
To the standard c is fixed an
eyer, a slide s¹ embracing the standard c carries an eyes and is adapted to slide
up and down the standard c finding the limit of its upwards movement at the
fixed eye r.

At the top of
the standard c.
The thread coming from the cop goes round the standard 6 and its wall n
to the eye s is passed through it, the eyes r and v, then inserted into the eye u
of the weight and guided through the eye w to the braiding point. On this way
the thread is guided and carried only by smooth portions so that nearly no friction
is produced and the thread is wind off very easily. The thread is thereby con-
tinuously spanned in the true manner till leaving the carrier as the weight is
kept during its operation in the upper portion of the standard c and may be
made therefore of any suitable length. In being raised the weight bears under
the hook shaped free end of the pawl releasing it from the brake i so that
the cop may be turned. The whole construction of the carrier is simple and
allows quick and convenient replacement of the cops.
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) A spool carrier for braiding machines composed of a foot a two vertical
standards b, c that are closed at the top by a clamp e, one of them being made
half circular and provided with a curved wall, the other being made hollow
for the insertion of the spanning weight, said standards having arranged between
themselves a spindle adapted to hold a cop of yarn, a pawl hinged to the clamp
reaching with its free end into the standard c and engaging with a brake forming
part of the upper end of the spool, fixed eyes r, v on the hollow standard and a mov-
able eyes, s embracing said standard substantially as and for the purposes herein
described and explained and as illustrated in the accompanying drawings.
2) In a spool carrier of the kind described the combination of a spindle having
tapered or otherwise shaped ends with bearings fitted with balls as described
and shown on the accompanying sheet of drawings.
