Description

June 26, 1934. L. L. MOORE THREAD COP Filed Dec. 1931 INVENTOR [0W5 L Moore BY/ATTORNZ'y/VrL/QLZ Patented June 26, 1934 UNITED STATES PATENT OFFICE THREAD COP Application December 1, 1931, Serial No. 57 8,284
2 Claims.
My invention relates to thread cops, and has special reference to universally wound thread cops that are used on high speed sewing machines.
The principal object of my invention is to provide a thread cop of this character which may be manufactured inexpensively, which may be subjected to the usual handling without danger of the ends of the layers sloughing off or becoming deranged, and from which the thread may be delivered at high speed without danger of snarling or frictionally catching on underlying convolutions of thread.
The several features of my invention, whereby this and other objects may be attained, will be readily understood from the following description and accompanying drawing, in which:
Figure 1 is a side elevation of my improved thread cop in its preferred form; and
Fig. 2 is a longitudinal sectional view taken on the line 22 of Fig. 1.
My improved thread cop as illustrated in the drawing comprises a core 2, a head 4 secured on one end of the core, and a mass of thread 6 wound on the core.
The core may be made of paper or other suitable material having its outer surface tapering as shown. The head 4 may be of wood having its inner surface tapering from its outer to its inner edge. The thread is universally wound on the core in overlying layers of uniform length. The several layers of thread are built up in such a manner as to provide the mass with a cup shaped lower end conforming to and in engagement with the tapering inner surface of the head 4. This causes the other or upper end of the mass to be tapering correspondingly to the head. Such winding of the thread also causes the outer surface of the mass to have a corresponding taper to that of the outer surface of the core.
In the use of the cop, the thread is drawn from the upper or tapering end of the mass. As the convolutions of the layers are successively drawn ofi from the mass, owing to the tapering outer surface of the mass, there is no danger of the hard or wiry thread usually employed in this type of cop frictionally catching or snarling on the unwound convolutions over which the thread is drawn. Also, owing to the taper of the upper end of the mass from which the thread is drawn, 60 there is not the danger of the convolutions of the thread sloughing off or becoming deranged at the end of the mass, as a result of more or less rough handling to which these cops are usually subjected.
It will be apparent that my improved cop may be inexpensively manufactured, and meets all the requirements of a satisfactory cop of the type described.
As will be evident to those skilled in the art my invention permits various modifications without departing from the spirit thereof or the scope of the appended claims.
What I claim is:
1. A thread cop comprising a core having its outer surface tapering toward one end thereof, a head on the other end of the core having its inner surface tapering toward the surface of the core, and a mass of thread on the core consisting of layers of thread of substantially uniform length universally wound on the core, with corresponding ends of the layers substantially engaging said tapering surface of the head, the other end of the thread mass having substantially the same taper as said head, and the outer surface of the mass having substantially the same taper as said core.
2. A thread cop comprising a core having its outer surface tapering toward one end, a head on the other end of the core, and a mass of thread on the core consisting of layers of thread wound on the core one upon the other with corresponding ends of the layers substantially engaging the inner end of the head, the end of the thread mass adjacent the other end of the core tapering, and the outer surface of the thread mass having substantially the same taper as the outer surface of said core.
