Improvements in Cop-tubes and Spindles for Use in Winding
Machinery.
1, THOMAS HENRY, Junior, of Tioga Street and Trenton Avenue, Philadelphia,
Philadelphia County, State of Pennsylvania, United States of America, Spinner,
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:-
This invention relates to certain new and useful improvements in cop-tubes and
spindles therefor for use in winding machinery having for its objects among others
to provide a simple and cheap holder attachment by the use of which all waste of
yarn is obviated, there can be no back winding, the holder cannot come in contact
with the yarn and the latter will run entirely off the cop-tube or cone and thereby
save all waste to the knitter, and an even selvedge is produced and the parts
cannot slip.
I form the paper cone or cop-tube with an eyelet to receive the projection on the
spring of the mandrel and locate this eyelet at a point beyond where the yarn is
wound; the projection of the spring is arranged near the end of the spring to
engage in the eyelet without extending beyond the outer face thereof and the end
of the spring is turned outward slightly to engage over the end of the tube or cone
to aid in holding the parts in their relative positions and enable it to be easily
disengaged from the cone or tube when desired.
Other objects and advantages of the invention will hereinafter appear and the
novel features thereof will be specifically defined by the appended claims.
The invention is clearly illustrated in the accompanying drawings, which with
the letters of reference marked thereon form a part of this Specification and in
which:
Fig. 1 is a view partly in elevation and partly in longitudinal section, of a spindle
embodying my invention.
Fig. 2 is a perspective view of the cone or cop-tube.
Fig. 3 is a sectional detail showing the eyelet in the cop-tube or cone.
Like letters of reference indicate like parts throughout the several views.
Referring now to the details of the drawings by letter A, designates the shell or
cone formed preferably of straw-board, paper pulp or some analogous material,
being in all respects similar to the well known forms of cop-tubes, except that in
proximity to its larger end it is provided with an opening in which is affixed an
eyelet B as seen in all of the views of the drawing. C is the mandrel or holder;
it is preferably of wood in conical form corresponding to the taper of the cone; it
is provided at the ends with the journals a, and b, as seen in Fig. 1 for the usual
bearings.
D is a spring held at one end within a channel or recess c, in the mandrel and its
outer end is extended in a direction inclined with relation to the axis of the
mandrel as shown in Fig. 1 and near its outer end it carries a projection d, at a
point where it will enter the eyelet when the mandrel is in its farthest limit within
the cone; one face of this projection is rounded as seen in Fig. 1 while its outer
face is at a right angle to the spring so that while the projection may readily enter
the eyelet as the mandrel is pushed into the cone it cannot be withdrawn until the
spring is forced inward to disengage the said projection from the eyelet. In order
to facilitate the disengagement of the projection from the eyelet the extreme end
of the spring is bênt outward as shown at d¹ and this outward bending of the end

page_text: of the spring adapts it to engage over the end of the cone and aid in holding the
parts in position.
The advantages of this construction are manifold; the cone is not pierced by the
projection of the spring so as to in any way interfere with the yarn either to injure
it or to hinder its being entirely unwound from the cone. The parts cannot shift
position relatively to each other and hence there can be no back winding; there
will be no uneven selvedge, and the empty cone can be easily adjusted in putting on
the mandrel. I also ensure an increase in the production. The eyelet may some-
times be omitted and the projection engage in the hole in the cone, but it is
preferred that the eyelet be present.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. A cop-tube provided with a protected aperture for receiving the retaining
device of a spindle, substantially as specified.
2. A cop-tube provided with an aperture in proximity to its larger end, combined
with a spindle having a retaining spring provided with a portion to engage said
aperture, as set forth.
3. The combination with a cop-tube provided with a protected aperture in
proximity to its larger end, of a spindle provided with a spring carrying a projection
adapted to enter said aperture when the spindle is inserted to its farthest limit
within the tube, as set forth.
4. The combination with a cop-tube provided with an aperture beyond the
yarn-winding surface combined with a spindle having a spring with a projection to
engage said aperture and having its outer end bent outward, substantially as and
for the purpose specified.
5. A cop-tube provided with an aperture beyond the yarn-receiving portion, as
and for the purpose specified.
