FLAT WIRE NAIL.

SEECIEICATION forming part of Letters Patent Noi 332,702, dated December 22, 1885.

(No model.)

To all whom it may concern.-

Be itknown that I, CHARLES W. DEAN, a citizen of the United States of North America, and a resident of South XVareham, county of Plymouth, State of Massachusetts, have invented a new and useful Improvement in Flat \Vire Nails, of which the following is a specification.

A patent of the United States was issued to me on the 18th of April, 1882, for a wirefence nail that was adapted and designed for fences made of round wire.

The Object of this invention is a nail adapted especially for fences constructed of fiat or ribbon wire-a purpose for which the nail pre- Viously patented, as above stated, is entirely unsuited.

Theinvention consisls in forning ribbonwire nails by cutting them successively from suitable bars or plates of metal, in a form approXiniate to their finished shape, with their legs sharp-pointed, divergent, and of different lengths, the longer leg forning a right angle with the flat diagonally-cut head of the nail-blank, and the shorter leg forming an obtuse angle with said head, and then bend ing the short leg so that it shall form on the inside a right or nearly right angle with the head and on the outside a curve, thus completing the nail, as hereinafter set forth.

Reference is to be had to the accompanying drawings, forning part of this specification, in which Similar letters of reference indieate corresponding parts in all the figures.

Figure 1 represents a c'osssection of a metal bar or plate of suitable shape for the manufacture of my improved nail. Fig'. 2 is a front view of the bar or plate having several successive transverse cuts made 011 one end thereof in the form of the nail-blanks. Fig. 3 represents one of the cuts or nailblanks detached. Fig. 4 represents a tinished nail.

A rectangular plae or bar, A, of wroughtiron, steel, or other suitable metal, preferably of great length compared with its width, is cut up from one end into a series of nailblanks, B, so that no Waste of metal results, as shown in Fig. 2. These nal-blanks or cut Sections B, with their diagonally-cut flat heads forming on both inner and outer edges right ang-les a a', respectively, with the longer legs and obtuse angles b b', respectively, on both edges with the shorter legs, are detaehed one by one, as indicated in Fig. 3, and the shorter leg of each one is then bent inward, as indicated in Fig. 4, so that its inner face or edge shall be parallel, or nearly so, with the edges of the longer leg and form a right angle, or nearly so, with the head, while its outer edge unites in a curve, c, with the outer edge of said head. The longer leg, however, remains as in the blank, at right angles to the head.

It will be observed that the angles at which the divergent legs of the blanl s or cut sections approach the edges of the blank-plate A cause the desired acute angle to be produced at the entering points of the nail, as indicated at d d, and it will also be seen that when completely formed, as above set forth, the nail will have a long' dat head that facilitates its driving, and a right-angled or nearly right-angled inner bend, f, for'ned by the junction of the head with the legs, and especially adapted for holding' fiat or ribbon wire closely to a fence-post or other Object.

Having thus dcscribed ny invention, l clain as new and desire to secure by Letters Patentl. A nail-blank having a sharp-pointed stem and a flat head whoseparallcl inner and outer edges or faces, respectively, form right angles with the corresponding edges of the sten, and which head terninatcs in abeveled and book-like point, as described.

2. A nail cut from bar netal with a sten and a head substantially at right angles to each other, formed by the cut that severs said nail from the bar, and having a short point projecting from said head parallel, with the sten, substantially as described.

In testimony that I elain the foregoing as ny invention I have sigued ny name, in presence of two witnesses, this 20th day of February, 1883.

CHARLES WV. DEAN.

JAMES G. SPROAT, EDGAR BOBINSON.
