srnclrrcarron forming part of Letters Patent No. 681,143, dated August 2o, 1901.

Application led May 27, 1901.

To a/ZZ whom it may concern: i

Beit known that I, CHARLES E. SLoooMB, a

is` a t specication.

` l. The purpose of this invention is to produce a nail having an end portion sufficiently fiattened to be readily clenched, and yet of sufficient rigidity to withstand compression j l strains to which itis subjected in being driven, and a penetrating-point which is of sufficient keenness to readily make an entrance, and

yet is so formed as not to turn in the driving operation when presented to material of considerable hardness.

Such nails are primarilyintended for use in the manufacture f lof boots and shoes and are particularly `.291

adapted to securing the heels, and when to loe` so used are preferably formed with a collar, beyond which is a spur or head portion 2 by means of which the top lift of the heel is y attached. United States patent of Hart, No.

376,988, dated January 24, 1888, shows a nail of that character, and still other forms have been patented. Nails of this kind are usul ally made of round-wire stock and the collar v p. y swaged or forged into shape, and it is com-` mon to provide them with tapering, oval, or awl points. I am also aware that the paty `enter Estabrook, No. 261,213, dated July 1s,

1882, shows a shoe-nail with a point of diamond-like cross-section tapering from the `body or shank to the penetrating-point.

In my improved nail the shank may be The pointor` clenched is flattened into an elongated i y ward the extreme end or penetrating-point,

which is formed by turning the four sides of theaxis of the nail at a greater angle than that of the taper,'the four inwardly-turned `faces uniting or merging into a comparatively keen penetrating-point, and I also prefer in like manner to carry or turn the edges point of the nail.

`advantages suggested at the beginning of this specification.

" In the accompanying drawings, Figure 1 is V an elevation; Fig. 2, an elevation at right angles to Fig. 1; Fig. 3, a view looking at tlie Fig. fl indicates the crosssection at the line s s of Figs. l and 2.

a represents the shank of the nail, usually and preferably round, and b is the flattened tapering diamond shaped point portion adapted to be turned over and clenched. Its four iiat sides l 2 3 4, suiciently close to the extreme or penetrating point of the nail, are turned more acutely toward the axis of the nail, as shown at 5 6 7 8, forming a secondary tapering diamond-shaped part of more acute taper and of relatively short length, the sides of which merge into the relatively keen penetrating-point marked fr. The lines of the more acute angles of the diamond -shaped part Z) are similarly carried inwardly toward the axis of thenail, as shown at b.

In the drawings, which show a shoe-heel nail, A is the ordinary collar, and c' the spur projecting beyond it for retaining the top lift.

I claim as my inventionl. A shoe-nail having a tapering diamondshaped end portion b, and a penetrating diamond' point formed by the four faces of said portion turned toward the axis of the nail at an increased angle.

2. A shoe-nail having a tapering diamondshaped end portion b, and a penetrating diamond point formed by the four faces of said portion turned toward the axis of `the nail at an increased angle, and by the edges forming the more acute angles of the portion b also turned toward said axis.

In testimony whereof I have hereunto subscribed my name.
