ting or otherwise damaging the same, there-.

fore the nail which forms the subject matter of the present invention -can be efliciently used in all kinds of wood, as well as leather, and all makes of wall board, other wall compositions and the like for which the nail will be particularly adapted.

A'further object of the invention is to provide a self-setting nail that includes a head having upstanding flanges to receive the blow of a hammer and a receiving depression for putty or other filler, with the underside of the head being formed with sharp penetrating edges for the purpose to set itself neatly in' materials receiving blow of the hammer.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated the nail'head under the in the accompanying drawings and specifically ointed out in the appended claim.

. In escribing my invention in detail, reference will be had to the accompanying draw-.

ings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a of my nail.. V

Figure 2 is a sectional view showing the application of my nail in wood or thelike.

Figure 3 is a similar view showing the application of my nail in'plaster board.

Figure 4 shows a top plan View of various shape heads for my nail.

Figure 5 are sectional views taken through nails to illustrate different shape shanks tllierei'or and showing the heads in bottom p an. v

Figure 6 is a sectional view of a shoe nail having the penetrating head and being ap-' out splitting or otherwise disfiguring the maplied to leather or other like material.

Figure 7 is a bottom plan View of the pointed end of the shank of my nail.

Referring to the drawings in detail, the referencenumeral 1 indicates the shank of the nail which forms the subject matter of the head 8 and a perspective view of one form.

present invention, and formed with the top of said shank is the novel head which in' the 7 present instance is provided with. upstanding cooperating flanges 2 having arcuate shape tops 3 formed integral with the remaining portion of the head as suggested in Figures 2- and 3 of the drawings. The flan e's-have their side edges formed integral with each other so as to provide a depression 4 which is adapted to receive putty, filler or other like matetial when the nail is driven home as shown in Figures 2 and 3 of the drawings. lVhile the head is of relative small diameter, it will be apparent that it will present a substantial hammer receiving surface and .the

flanges thereof will amply prevent the ham-- mer from slipping therefrom dueto the beveled edges of said flanges as shown.

The underside of the heads are slightly concaved, and when a hammeris applied to the flanges, the head will have a tendency to assume the position as shown in Figures 2 and 3 with the result that the lower portion of the head is provided with what may be termed penetrating points 5 so that the nail will effectively countersink its head with the result the use of a. nail punch or set will be eliminated.

In Figure 4; I have illustrated various forms of heads for my nail and in this figure I have shown a which is also shown in Figures 1 to 3 inclusive, a diamond shape head 7, a'rectangular shape head-9 which has a'rounded outer edge. In all these figures it will be noted that the head includes the flanges for .the purpose as above set forth.

substantially square shaped head 6 10 and this lower end including the tapered portion is provided with longitudinally extending grooves 11 which taper toward their ends as best shown in Figure 1 of the drawings sothat a needle point penetrating end 12 is provided and at the same time the grooves 11 enable the nail to quickly and easily penetrate any material with very little effort on the part of the operator and with terial.

' In Figure 6 I have illustrated the nail for application in leather, and the shank which is indicated by the reference numeral 13 is tapered from its head 14 which is constructed my inve thescope of the appended claim.

What I'claim is:

A nail of the character described comprising a shank having a penetrating end, a head formed on the opposite end of said shank, up-

standing flanges formed integral with said head and providin a filler receiving depression, said flanges aving sharpened upper edges which are arcuate in formation, said head being provided with a slightly concaved lower portion, and said flanges being formed with each other and with said head in a manner whereby the lower surface of said head will provide penetrating edges when struck by a hammer and result. in the head countersinking itself.v

In testimony whereof I afiix my signature.

MILTON B. BEAN.
