FREDERICK FLAD, OF PHILADELPHIA, PENNSYLVANIA.

SHOE-NAIL.

SPECIFICATION forming part of Letters Patent No. 374,590, dated December 13, 1887.

Application filed J unuary 2S, 1887. Serial No. 225,769. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK FLAD, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Shoe and other Clinch Nails, which improvement is fully set forth in the following specification and accompanying drawings, in which the several figures represent side elevations of shoe or other clinchnails embodying my invention.

Similar letters of reference indicate corresponding parts'in the several figures.

My invention consists of a nail which may be readily clinched, as willbe hereinafter fully set forth.

Referring to the drawings, A represents a nail embodying my invention, the same being formed of iron, brass, or other suitable material, having in its shank or body near the point of the nail the depressions B, which thin said blank at the places occupied by said depressions. It will be seen thatwhe'n the nail is driven into a shoe or other article and the point strikes the last or some other bed or anvil on which the article is supported the point of the nail, which is substantially in an axial line with the shank, is deflected, thus causing the bending of the shank at the neck 0, the

latter being formed by the reduction of the shank due to the depressions, it being seen that the depressions extend transversely or at an angle to the length ofgthe nail. The leather or other material will be surely clinched by the nail, and the latter will retain its hold in a firm and reliable manner.

In order to strengthen the neck 0, the faces of the same have ribs D thereon, the same extending in the direction of the length of the shank and acting as a re-enforce without interfering with the bending and clinching action of the nail.

In manufacturing my nail I may take any ordinary wire-nail machine and provide the pressing or clamping dies thereof and any separate part thereof with a projection or projecting part corresponding to the depressions of the nail. When the dies hold the wire firmlyrin readiness for the blow of the hammer, the aforesaid projection is adapted to act on the wire, so as to produce the depression or depressions B. I may, however, provide the cutters of themachines with such features that when the point of the nail is cut or produced the indentations or depressions may be simultaneously formed.

I am aware that it is not new to form a nail with a cut-away or recessedportion for weakening the same, so that the nail when driven into the leather or other'material and meeting resistance on the opposite side thereof may be bent so as to clinch or grip the material, and thus be firmly held in place, and such I do not broadly claim, but I am not aware that the specific construction herein set forth, wherein the recessed portion is on opposite sides of the nail and the lower portion of the neck formed by said recesses is strengthened by ribs,as shown herein,has ever before been used.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, isv 1. A shoe nail formed of a single piece of wire of uniform thickness, with its point in the axial line thereof and having on each of two of its opposite sides and near the said point a single depression, substantially as and for the purpose set forth.

2. A shoe-nailhaving a neck near its point formed by recesses on opposite sides of the shank, said neck having the ribs D, substan.

tially as and for the purpose set forth.
