No. 234,222. Patented Nov. 9,1880.

NAIL.
} SPECIFICATION formingpart of Letters Patent No. 234,222, dated November 9, 1880.
Application filed March 4, 1880.
To all whom at may concern:
Be it known that I, LEWIS J. ATWOOD, of Waterbury, in the county of New Haven and State of Connecticut, have invented an Improvement in Shoe-Nails, of which the following is a specification.
Shoe-nails have been made of wire with the bodies notched or formed with screw-threads, and the points have been cut diagonally, so as to clinch when driven against the metal-faced last. Spikes have also been made in a similar manner. In some instances the bodies of spikes have been grooved circumferentially, so
,; that the spikes resembled a series of conoids. k 1 5 My invention is made for rendering the wire shoe-nail stiff, so that it will drive correctly,
for increasing the diameter of the nail, so that it is largerthan the wire from which it is made, and for saving in the stock by preventing any loss of the metal employed in making the shoenails.
In the drawings, Figure 1 represents the shoe-nail of about the usual size, and Fig.2 is an elevation of such nail magnified, so as to show the same more clearly.
The wire from which the nail is made is of the proper diameter, as shown, at the end a and near the point I). The wire is cut diagonally to form a point, b, that will turn over 0 and clinch when driven.
The body of the nail has circumferential grooves c c, with intervening duplex ribs 11 i. Said ribs are of greater diameter than the wire (ModeL) a, from which the nail is made. This is effected by the action of mechanism that rolls 5 or presses in the grooves, and in so doing throws the metal from the grooves into the ribs and causes them to stand out from the surface of the wire and stiffens the wire.
In consequence of the ribs being of greater diameter than the wire, the shoe-nails will hold into the leather with greater firmness, and the nail will drive with accuracy, because the point portion is of plain wire cut diagonally and without ribs or grooves. The leather, which usually is wet, will contract as it dries, and harden into the grooves, and the ribs will penetrate the leather and form a most reliable holdfast, and the point will turn over and clinch, and the blow, in driving, will form a rivet-head.
I claim as my invention- The wire shoe-nail with a single diagonal cut on one side of the plain portion of the wire to form the point, and with concave circumferential grooves in the body of the nail, and intermediate duplex ribs that are of greater diameter than the plain wire of the point, for the purposes and as set forth.
Signed by me this 27th day of February, A. 60 D. 1880.
L. J. ATWOOD.
