Patented Dec. 5, 1950 UNITED STATES PATENT OFFICE 2,533,062 STAPLE NAIL Edward J. Spink, Council Blufis, Iowa Application December 20, 1948, Serial No. 66,361

1 Claim.

The present invention relates to fastening devices and more particularly to staples.

It is obiect of the invention to provide a device which is so constructed and the parts thereof so cooperatively arranged with respect to each other that fence wires, metal lath, and the like, may be attached to wooden fence posts and studdings, in instances where the wood is comparatively hard, in a ready and secure manner.

It is well known that conventional, or approximately horseshoe shape Wire staples become deformed during a driving of the staples into wood, and particularly comparatively hard wood, whereby fence wires do not become. securely attached to posts and the like. Also, it is well known that often during a use of conventional staples, the latter bend under the first blow of a hammer, whereb an operator discards the staple and uses another with an attendant loss of material, time and labor, and the instant invention x thereof may be partially imbedded into a fence post for supporting a fence wire thereon whereby a half mile of wire be supported upon a line Of posts and upon the shanks of like devices for the purpose of permitting the operator to stretch the wire before the staples attached to a post are driven home for securely locking wire to a post.

Another object of the invention resides in the provision of a staple-nail, as described, having a flared or flanged head-end for convenient removal thereof by a claw hammer.

A still further object of the invention is to provide a device which is so constructed that blows of a hammer will be applied in alignment with the longitudinal length of the main body portion or shank of the new device.

Other and further objects and advantages of the invention will be understood from the following detailed description thereof:

Figure l is a side view of the new device.

Figure 2 is a top plan view thereof.

Figure 3 is an end view thereof.

Figure i is a top plan view of a row of fence posts having specimens of the new device partially imbedded therein for supporting a fenoe'wire thereon prior to a stretching of the latter.

Figure 5 is a side view of one of the fence posts shown in Figure 4.

Referring now to the lead pencil sketches for a more particular description, the new device includes a main body portion or shank it] which is of an elongated rounded shape and is provided with a sharp point l2 at one end thereof and having a flange or head M at its other end.

The head It, which is substantially rectangularshape in cross section, is formed integral with an interconnection or lug portion E6, the latter being disposed at a right angle with respect to the shank H). with an arcuate concave under surface for receiving a fence wire.

Adjacent the free end It or the lug I6, a tang Z9 is provided which is formed integral with said lug.

The shank it! and tang 2e are disposed in spaced apart parallelism with respect to each other for providing a rounded notch 22 therebetween for purposes later described. The free end 24 of the tang 20 terminates in a sharp point.

As best shown in Figure 1, the upper surface or protrusion 25 of the head H8, in alignment with the shank Iii, is convexially round on its upper side and is of a greater height and is disposed farther from the interconnecting portion it than the uppermost portions of the tang 29 so that hammer blows will be absorbed by the protrusion 25 and the main shank it to the exclusion of the tang 20, the force of the blow being longitudinal of the main shank I0.

As best shown in Figure 2, the lug I6 is of lesser transverse width preferably than the width or diameter of the head [4 for the purpose, primarily, of conserving material.

Referring to Figure 5, it will be seen that at times when the shank I0 is partially driven into the post 26, the force of the blow delivered manually by the hammer 50 is transferred in alignment with the longitudinal axis of the shank I0, whereby the shank l0 does not become bent since it is of an adequate diameter.

In operation and in order to attach the fence wire 28 to the post 26, the new device is first applied by a hammer 50, as shown in Figure 5, namely, by driving a portion of the shank into the post 26.

Further specimens of the new device are applied similarly to the posts 30, 32 and 34 of the row of fence posts shown in Figure 4, whereupon the wire 28 is placed upon the upper sides of the shanks of the said specimens and the operation repeated until about a quarter mile length of wire has been placed on posts, whereupon a wire stretching device is applied to an end of the wire at a time when the other end of the wire is anchored for stretching the wire. The opera- The lug portion 16 is provided 3 tor then drives said specimens home, whereby the tang 28 becomes imbedded in the post, together with the shank II) for securing the wire 28 between the posts and the shank, tang and the lug of each staple-nail.

From the foregoing description, it is thought to be obvious that a staple-nail constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modi-- fication without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself. to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as claimed.

I claim:

In a barbed nail, the combination which comprises an elongated cylindrical shank having apoint on one end, said shank having a tapering section with flat sides leading to the point, ahead on the shank positioned on the end opposite to that on which the point is positioned, said head comprising a flat section rectangular-shape in cross section positioned perpendicular to the shank and extended from one side thereof, said head extended in a plane parallel to planes through two opposite fiat sides of the point whereby with the said fiat sides of the point vertically positioned the head is retained in an upwardly extended position, the width of the said fiat section of the head being greater than the diameter of the shank and the peripheral surface of the shank being blended into the under surface of the fiat section of the head with arcuate surfaces, a tang parallel to and extended in the same direction as the point of the shank carried by the outer extended end of the fiat section of the head and the inner surface thereof blended into the under surface of the fiat section withan arcuate surface, and a dome-shaped hammer blow absorbing protrusion positioned on the outer surface of the flat section of the head and aligned with the said shank, said flat section of the head also having a reinforcing lug portion on the outer surface connecting the dome-shaped protrusion to a smaller similar protrusion thereon and aligned with the said tang.
