JOHN O. MGKEAN, OF'WESTFIELD, MASSACHUSETTS, ASSIGNOR TO FOSTER.- MACHINE COMI'AN'Y, OF WESTFIELD, MASSACHUSETTS,

A CORPORATION OF MASSACHUSETTS.

COP-CONE.

Application filed September To all whom it may concern.

Be it known that I, JOHN O. MOKEAN, a citizen of the United States, and resident of Westfield, in the county of Hampden and State of Massachusetts, have invented a new and useful Improvement in Cop-Cones, of which the following is a specification.

My invention comprises a cop cone having two different tapers as distinguished from the cones in common use which have a single straight taper.

My invention more particularly comprises a cop cone having a gradual taper extending for a distance from its larger end, said gradual taper terminating at the smaller end of the cone in a steeper taper, preferably straight, although it may be slightly convex or slightly concave if so desired.

On a single taper cone as hereinbefore used, the extreme end of the smaller diameter builds up somewhat larger than the tru taper. This is one of the disadvantages which it is intended to obviate by the double taper cone of the present invention.

Another advantage of the double taper cone is that it gives more clearance to the cop than a single taper cone unless the single taper is very steep. In a very steep taper cone it is impossible to get the yardage in the cop. In the double taper cone a greater mass of yarn with the same clearance of the thread maybe wound. The double taper cone seems to have a firmer nose and is not so liable to be injured in the rough usage to which it is subjected, as the nose or smaller end of the cone seems to be protected by the steep taper at the smaller end of the cone. Furthermore, in a very steep taper to allow for the proper clear ance, the yarn has a tendency to come off in coils and snarls. Thisis obviated by the double taper of the cone, the yarn seeming to cling much better and not to uncoil faster than required.

A practical embodiment of my invention is represented in the accompanying drawings, in which,

Figure 1 represents my improved double cop cone when made of paper, the cone being shown in its operative relationship to its driving roll.

Fig. 2 represents a similar view a wooden double taper cone.

Fig. 3 represents in outline, the cop wound showing Specification of Letters Patent.

on the cone,

therefor.

F g. 4 represents a detail view showing another form of steeper taper at the smaller end of thecone.

Fig. 5 represents a similar view, showing still another vform of steeper taper at the smaller end of the cone.

The driving roll which is herein shown, comprises a cylindrical member 1 and a flarmg member 2, both mounted on a suitable supporting shaft 3. In the form shown in 1g. 1, the cop cone is represented as a paper cone and it has a gradual taper as shown at 4, extending a distance from its larger end, said gradual taper terminating in a steeper taper shown at 5, at 'its nose or smaller end.

In the form shown in Fig. 2, the cop cone is of wood or other suitable material. In both of the forms of cop cones illustrated in Figs. 1 and 2, the steeper taper 5 of the cone is straight.

In the form shown in Fig. 4, the steeper taper of the cone is shown as sli htly convex, while in the form shown in B ig. 5, the steeper taper of the cone is shown as slightly concave.

It will be understood that in the winding machine, the gradual taper 4 of the cone is opposite the cylindrical member 1 of the driving roll and the steeper taper 5 of the cone is opposite the flaring member 2 of the driving roll. This arrangement of the driving roll and double taper cone ermit's the winding of the cop so as to produce the advantageous results hereinbefore set forth and eliminates some of the disadvantages which have heretofore obtained where a single taper cone has been employed, especially with the driving roll having the flaring member herein illustrated.

It is evident that various changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not intend to limit myself to the particular embodiments herein shown and described, but,

What I claim is 1. A rigid cop cone, its winding surface having a gradual taper terminating at its smaller end in a steeper taper in the same direction.

together with the driving roll 2. A rigid cop cone, its winding surface having a gradual taper terminating at its smaller end in a straight steeper taper in the same direction.

3. In a winding machine, the combination with a driving r011 divided into a cylindrical member and a flaring member, of a rigid cop cone, its winding surface having a gradual taper opposite the cylindrical member terminating at its smaller end in a steeper taper in the same direction opposite the flaring member.
