COM BINED NEEDLE AND CORD.

SPECIFICATION forming part of Letters Patent No. 380,773, dated April 10, 1888.

Application filed May 20, 1887. Serial No. 238,821. (No model.)

To all whom it may concern.-

Be it known that I, FRANKLIN A. SMITH, J r., a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in a Combined Needle and 00rd; and I do declare the follow- 1ng to be a full, clear, and exact description of the invention, such as will enable others skilled 1n the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the lettersand figures of reference marked thereon, which form a part of this specification.

This invention relates to a new and improved needle permanently secured to a cord or ligature, by means of which two or more arholes may be secured together, as by sewing, the object being to provide a needle which shall puncture material easily and present the least possible friction in passing through the same, and also to form a hole insaid material, through which the cord or ligature attached to the needle may be easily drawn.

To this end my improvementconsists, essentially, of a one-piece needle made from a sheetmetal strip bent toform a cylindrical tube or envelope, one end of which completely encircles the free end of a cord or ligature, being swaged or compressed upon the same, the edges of the tube or envelope being brought together and inturned and embedded into said cord or ligature to securely retain it thereon, the opposite end of said tube or envelope .being cut away diagonally at one side and flattened and sharpened to form a puncturingpoint, (being broader at a point immediately behind the said end than the diameter of the remainder of the needle and the 00rd,) all as will be hereinafter more fully described, and pointed out in the claim.

Figure 1 represents a perspectiveplan view of the needle having a portion of the cord or ligature attached. Fig. 2 is a side View of the same. Fig. 3 is a plan view showing the end of the cord or ligature lying in the needle-strip prior to being secured therein. Fig. 4 is a cross-sectional view of the same. Fig.

5 is a cross-sectional view of the needle taken through line or x of Fig. 2. Fig. 6 is a similar cross-sectional view, showing the edges of the needle-strip brought together and inturned and embedded into the cord or ligature.

In carrying out my improvement the needle A is made from a strip of thin pliable sheet metal first bent intoa U shape, as shown in cross-section in Fig. 4. The free end of a cord or ligature, B, is then laid in said strip, occupying about one-half the length thereof, as shown in Fig. 3. The edges of the strip are then brought together by bending and swaging, completely encircling said cord or ligature, and clamping or compressing said strip securely thereon, the edges meeting, forming a cylindrical tube or envelope upon the end of the cord or ligature, as shown in Figs. 2 and 5 of the drawings. The opposite end of the tube is then sheared or shaved diagonally toward the free end cutting away and removing a portion of one side of said tube, as shown in dotted lines in Fig. 2. The end is then ground or sharpened to form a penetrating-point. The angled portions act back of the point are then flattened and broadened, making it wider than the diameter of the opposite end of the needle, as fully shown in Fig. 1.

For the purpose of additional security in clamping the needle to the cordor ligature, the edges 0 c of the metal strip'upon being brought together are inturned and embedded into said cord or ligature during the operation of compressing the stripthereon, as shown in cross-section in Fig. 6. This willefiiectually prevent the cord or ligature from being drawn out of the needle when employed on a fabric which offers a great amount of resistance on 7 being drawn through.

The lower surface of the needle is in a continuous plane, the diagonal out being made on one side only. The edges of the cut-away portion being sharpened by flattening form a peculiar-shaped point which willeasily puncture any thickness of material, and being larger than the diameter of the shank of the needle and the cord said cord is easily drawn through the hole thus punctured. The needle and cord or ligature are made of a proper diameter, according to the uses to which they may be designed to be employed.

Having described my inventiornl claim- In combination with a cord or ligature, a

one-piece sheet-metal needle consisting of a I ligature, and sharpened to form a penetrating cylindrical tube the edges of one end of which end, substantially as herein set forth. IO are brought together and inturned and embed- In testimony whereof I affix my signature in ded into said cord to securely attach the neel the presence of two witnesses.
