United States Patent'Ofifice Patented Mar. 10, 1970 3,499,359 EASY PULL STAPLE John J. Yrjanainen, 1214 /2 Pleasant St., De Kalb, Ill. 60115 Filed Oct. 23, 1968, Ser. No. 769,962 Int. Cl. F16b 15/00 US. C]. 85-49 2 Claims ABSTRACT OF THE DISCLOSURE This staple, designed for driving into wood, has a T- shaped driving head on the outer end which in no way interferes with driving the staple in, enables easy pulling out with a claw hammer or crow-bar, whereas the legs of the staple are designed to take a good hold in the wood by virtue of the transverse serrations on the outer parallel sides of the two legs and the saw-toothed projections on the outwardly diverging inner sides. The relatively large rectangular head end portion of the body of the staple gives adequate support for the legs so that they will not spread perceptibly when driven into the wood. The staple is punched from sheet metal and thereafter subjected to hardening, so it can be produced economically and sold at a low price.
This invention relates to staples and is more particularly concerned with one designed for use in the fastening of barbed wire, conduits, concrete forms, and wherever easy driving is of advantage as well as good holding power but at the same time easy pulling, the staple body being stamped from sheet metal to the form desired with friction serrations transversely of the outer parallel sides of the legs and saw-toothed projections on the downwardly diverging inner sides of the legs, which do not interfere with easy driving of the staple and yet serve to make it harder to pull out or work loose under strain. A T-shaped head formed integral with the outer end of the staple in no way interferes with driving of the staple in, but enables easy pulling out with the claw end of a hammer head or the claw on a crow-bar.
The invention is illustrated in the accompanying drawing, in which:
FIGS. 1 and 2 are a side view and an edgewise view, respectively, of a staple made in accordance with my invention;
FIG. 3 shows one of these staples driven into a post, holding a heavy wire;
FIG. 4 shows how the staple is driven into the post;
FIG. 5 is a view at right angles to FIG. 4, illustrating how the staple can be pulled out readily, and
FIG. 6 is a perspective showing how a piece of fiat sheet metal is being marked off with a scribe tool for maximum use of the material in the ultimate punching of the staples.
The same reference numerals are applied to corresponding parts throughout the views.
Referring to FIGS. 1 and 2, the staple 7, which can be economically stamped from sheet metal and thereafter subjected to a suitable degree of hardening, is of generally V-shape, providing the two legs 8 and 9 extending from a generally rectangular head portion 10 that has, at the middle thereof, an outwardly extending T-shaped projection 11 on the horizontal center line of the staple, this form being easily stamped from a strip 10 of sheet metal as shown in FIG. 6', in such a way that one set of staples indicated by the scribing at 13, is produced from one edge portion of the strip, while another set 14, in reversed relation to the set 13, are produced from the other edge portion of the strip, the legs of the staples of the two sets being in nesting relationship to one another, so that there is a minimum waste of material, as appears between the head ends of the staples, as indicated at 15. a
The staple legs '8 and 9 have zig-zag serrations 16 provided transversely of their parallel outer edges and sawtoothed projections 17 provided on the inner diverging edges of said legs. The fairly large generally rectangular head portion 10 gives ample strength to the body of the staple so that there is no likelihood of the legs 8 and 9 diverging perceptibly when driven into a post, as shown at 18, to fasten a heavy wire 19 or barbed wire, the present staples being well adapted for the fastening of wire, barbed wire, conduit, concrete forms and other things, as indicated before, as, of course, they may be made available in different sizes to suit different requirements.
In operation, the T-shaped head 11 i large enough to enable driving the staple in with a hammer H, as seen in FIG. 4, the leg 20 of the T 11 being narrow enough to fit between the claws 21 of a hammer for withdrawal of the staple, as shown in FIG. 5, the block indicated at 22 providing a suitable abutment for the other end of the hammer head in such an operation. In some cases crow-bars are used to equal advantage. In the driving in of the staple it is obvious that the wood is compresed between the diverging inner edges 17 of the legs 8 and 9, assuring a good firm hold on these legs, while the serrations on the outer edges 16 of the legs, which remain in substantially parallel relationship, further insure a good hold in the wood. Spreading of the legs is minimized as a result of the fairly large rectangular form of the outer or head end portion 10 of the staple. Naturally, these staples can be made available in different sizes for different purposes, it being the width between the inner ends of the legs 8 and 9 at the head end portion 10 that determines in most cases the use to which the staple can be put, allowing, of course, for the fact that in some instances the staples need not be driven in all the way, as that one shown in FIG. 4, a larger space being made available in that way to receive a larger part to be held.
It is believed the foregoing description conveys a good understanding of the objects and advantages of my invention. The appended claims have been drawn to cover all legitimate modifications and adaptations.
I claim:
1. A stamped sheet metal staple having two spaced coplanar legs both of generally triangular form so as to provide fairly sharp entering ends, the inner ends of said legs being joined by a coplanar transverse head portion of generally rectangular form having a narrow coplanar extension at the middle of its outer edge defining the leg of a coplanar generally T-shaped driving and pulling projection on the longitudinal center line of the staple, the cross-portion of which is spaced from the transverse head portion to the extent of the length of the leg portion of the T, the cross-portion of the T-shaped projection being of a length longer than the leg portion of the T, and the leg portion of the T being of a width adapted to be received between the claws of a hammer or crow-bar for withdrawal of the staple from the wood into which the staple may be driven, the inner edges of the legs diverging toward the entering ends, and the outer edges of said legs being substantially parallel, the staple including saw-toothed projections on the inner edges of said legs that are shaped to enable easy driving into the wood but resist loosening and removal.
2. A staple as set forth in claim 1 including small roughnesses on the outer parallel edges of said legs to further resist loosening and removal.
