SPOOL OR BOBBIN.

SSPECIPICATION forming part of Letters Patent No. 344,928, dated July 6, 1836. Application filed September 24, 1885. Serial No. 178,026. (No model.)

To aZZ whom, it may concern.-

Be it known that I, OSCAR F. VVAII, a citizen of the United States, residing at Springfield, in the county of Windsor and State of Vermont, have invented certain new and useful Improvements in Spools or Bobbins, of which the following is a specification.

My invention is an improvement in wooden spools or bobbins which are re-enforeed by strengthening material let into an annular groove at one end thereof; and the object of my invention is to utilize wire for this purpose, and to firmly secure the same to the wood.

In the accompanying drawings, Figure 1 is an end View of a; spool or bobbin which embodies my invention. Fig. 2 is a central longitudinal section of a portion of the same. Fig. 3 is a side elevation of the wire with which said bobbin isre-enforced. Fig. 4. is a side elevation of a wire wound or braided with a fibrous material, and Fig. 5 is a perspective view of the same cut into suitable lengths and bent into rings for a reenforce.

A designates a spool or bobbin, in one end of which is an annular groove filled by re-enforce a. This re'enforce is formed of wire, a fibrous material, and cement. I prefer to combine the fibrous material with the wire by first winding or braiding the wire with the fibrous material in continuous lengths, as shown in Fig. 4. This fibrous material is thoroughly saturated with glue or other adhesive cement. The covered wire is wound into the form of a helix of any desired length,

and then cut into short sections of about three combined wire, fibrous material, and cement is firmly pressed into the annular groove to form the re-enforce a. There should be a suf ficient amount of the fibrous material to fill all the interstices within the groove. The portions which surround the wire; within the groove in Fig. 2 are intended to represent the combined fiber and cement. When the cement is properly hardened, it firmly adheres to the wood and fiber, and binds the wire firmly in place.

Another manner of forming the reenforce is illustratedin Fig. 5. The wire is wound or braided in continuous lengths, and then formed into rings, which are placed within the annular groove at the end of the bobbin, one upon the other, so as to break joints, as indicated in Fig. 5. Before thus placing the rings within the groove the fibrous material is thoroughly saturated with cement. The rings thus cemented and placed are firmly pressed, so as to cause thefibrous material to fill the interstices.

I have herein illustrated and specifically dcscribed two different ways of preparing the combined fiber and wire; but it may be prepared in other ways, and produce substantial] y the same article.

I do not claim, broadly, a spool or bobbin having a re-enforce secured within an annular groove at the end of the bobbin, as I am aware that the same is old.

I claim as my invention- The herein-described spool or bobbin, having an annular groove at one end filled by a re-enforce composed of wire, fibrous material, and cement, substantially as described, and for the purpose specified.
