SPOOL.

Specification of Letters Patent.

Patented Jan. is, rare.

Application filed November 30, 1912. Serial No. 734,233.

In the accompanying drawings-Figure;

1 is a perspective view of a spool filled with thread and made according to the preferred form of my invention. Fig. 2 is a perspective View of an empty spool.

Spools made according to my invention possess the general characteristics in functlon and appearance of spools now in common use for carrying sewing thread, Whether linen, cotton or silk,-that is to say, they have a cylindrical body that is longitudinally perforated, and with heads or flanged ends, the latter preferably tapering inwardly and being cylindrical in outline.

There are well known advantages incidentv to this form of spool, and my invention has been developed to depart from this shape as Such spools, however, are subject to the objection that they roll easily, so that care needs to be exercised in handling them lest they roll from the surface on which they may be placed.

In carrying out my invention I provide the heads or flanged ends of the spool with low projections or bosses extending outward from'the curved rims or edges of the heads, these projections being preferably four in number and arranged diametrically opposite each other, as thereby the spools so constructed can be packed in boxes such as are provided for spools of corresponding size as now constructed.

Referring to the drawings, A designates the spool as a whole, and B, B, the heads or flanged ends thereof. These heads or ends terminate, as usual, in narrow edges 5, b,

which are approximately cylindrical. From the periphery of these edges extend projections C, C. In the preferred form of invention, the projections areof the same material as, and are integral with, the heads or flanges B, and they are formedby compressing the flanges or heads after being formed between such projections, toward the central or longitudinal axis of the spool, thus reducing the diameter of the cylindrical portions of the heads to the desired size. It will be readily seen that the projections C of a spool such as described, will operate to prevent the spool from rolling to any considerable extent. At the same time they serve to' prevent the thread from slipping off the ends of the spool when the latter is filled to its full capacity.

It is often customary in making spools to provide upon the outer face of the head an ornamental border a? immediately adjacent to the edge 6. It will be seen that a spool, formed as described by compressing the head between the projections C, will not destroy such border, but rather give it a distinctive and pleasing effect. At the same time the general appearance of the spool is not destroyed and the spaces at theends of the spools for printing or other'display matter are not interfered with.

What I claim is 1. Aspool for sewing thread having a solid body with heads substantially circular in outline, from the peripheral edges of which extend low projections, such projections being integral with the material of the heads, substantially as set forth.

2. A spool for thread having heads or flanges at its ends'substantially circular in outline and from the edges of which extend projections'or bosses integral therewith, the material of the flanges or heads of the spools between the said projections being compressed and reduced in diameter.
