COMPLETE SPECIFICATION.
Improvements in Spindles for Yarn or Thread Winding Machines.
I, ARTHUR AUSTIN BRIGHAM, of 186 Devonshire Street, in the City of
Boston, County of Suffolk, State of Massachusetts, United States of America,
Dealer in Textile Machinery, 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 invention relates to conical spindles for winding machines, particularly to
means or a device combined with the spindle for securing thereon the shell or cone
upon which the yarn or thread is wound. The invention consists of a spiral thread
formed on the spindle substantially as hereinafter described and specifically pointed
out in the claims.
In the drawing forming a part of this Specification,
Figure 1 shows a spindle embodying my invention when the spiral thread is
formed on the small part thereof.
Figure 2 is an end view of the spindle.
Figure 3 shows a spindle having the spiral thread on the greater part thereof.
Figure 4 shows a shell or cone adapted to enter upon the spindle shown in
Figure 3.
When the shell or cone, upon which the yarn or thread is to be wound, has a
smooth or even interior surface it is best, in order to carry out my invention, to
form a fine spiral thread on a metallic portion of the spindle as shown in Figure 1.
The spindle A, having the two usual extensions a to enter the ordinary bearings
therefor, form, as to the greater part of the conical portion thereof, of wood
or other suitable material, but the smaller part, and preferably that end c of smaller
diameter, I form of metal. Upon this end portion I cut or form a spiral thread d.
At the larger end of the spindle arms or radial projections are constructed of
suitable shape to be readily seized by the fingers. In operation, the shell or cone,
usually made of paste-board, is thrust upon the conical spindle, and then, by
slightly pressing the spindle into the cone and giving the spindle a revolution or
part of a revolution by means of the arms or radial projections e while the cone
is held stationary, the thread is screwed sufficiently into the material of the cone
to cause the latter to be held so securely on the spindle as not to become loose
thereon when placed in the machine and during the process of winding.
For
For certain kinds of winding it is desirable to corrugate or groove the exterior
of the shell or conc. Such grooves may be spiral and so formed as to make a
spiral thread on the interior surface of the cone B, as illustrated in Figure 4.
such conce I form a spiral thread on the greater portion of the spindle as shown
in Figure 3. This thread corresponds to that on the interior surface of the cone.
Thus by revolving the spindle in the suitable direction, while in the cone which is
held stationary, the spindle will be screwed into the cone, so that the latter will be
held securely thereon.
Screwing the spindle into the cone as specified is a very simple operation, as, also,
the reverse movement to remove the cone from the spindle, while the means or
device can be very easily made and is of slight cost.
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 :-
A conical spindle for a winding machine provided with a spiral thread on the

page_text: exterior surface thereof and with arms or projections at the end of the spindle to
facilitate screwing the spindle into a shell or cone, substantially as set forth.
