Speciflcation of Letters Patent.

Patented Aug. 5, 1919.

Application filed. August 21, 1917. Serial No. 187,394.

To all 'whom z't 'may concern:

Be it known that I, AUsTIN C. LnscHaN- DER, a citizen of the United States, residlng at Port Blakele in the county of Kltsap and State of Wiishington, have invented a new and useful Staple, of which the following is' a specification.

M invention relates to improvements m stap es, for the purposes for whlch staples are generally used-for instance, for fastening Wire to fence posts, etc., and the object of my mprovement is to provide a staple, which, when driven in place, will not work its way out, n01` can it be easily removed.

I attain these objects. by the staple lllustrated in the accompanying drawing, in which- Figure 1 shows the staple. Fig. 2 shows the shape of the. staple after bein driven.v

Each leg of the staple is provi ed with a barb as shown, 1 and 2 in Fig. 1, said barb extending outwardly from the end of each le and being crosswise from the outer side o the staple leg, there being but a single edge from the barb to the oint of the staple leg (3 and 4 in Fig. 1 Said barb and said edge 'on each leg are directly opposite and in the same relative-position on each leg of the staple; that is if a straight line were drawn from 1 to 2 in Fig. 1, it would pass directly through the center of each leg of the staple, or if a straight line were drawn from any point on the edge (from 3 to 4) to acorresponding point on theedge from the barb to the point on the other staple leg, it would pass directly through the center of each staple leg.

In driving the staple the force of the blows, and the resistance of the substance into which the staple is driven, exerts pressure along the edges of the barbs 1 and 277, 1, causing the legs of the staple to bend in substantially as 1s shown in Fig.

2, thus giving the staple a more secure hold on the Wood or other substance while at the same time the legs are not twisted but remain in the same plane. This gives the staple a secure hold, and at the same time makes the driving of the staple easier than if there was a twist to said barbs or legs. Cedar Wood is commonly used for fence posts, and being a' straight grained Wood, thel ordinary staple, through action of animals rubbing against the Wire, the action of the elements and other causes, commonly becomes loose falls out and a1- lows the wires to dro down, necessitating continual repairs. 's improved staple can lbe easily driven, and by reason of the barbs as shown, and the fact that the legs of the staple, upon the sta le being driven, bend in substantially as s own in Fig. 2, the staple is held secure and in place. It is apparent that this bending of the legs and-the resistance of the barbs would make the staple hard to remove, holding it in place much more efl'ectively than the ordinary and common staple would be held. It is an inexpensive staple to manufacture, each barb having a single, unsharpened edge, and it is a staple that can be used for 'all the pux'mses for which ordinary staples are adapte I claim: A staple, each leg of which is provided with a projection centrally located on the outer side near the point and terminating at the point the a ex of the projection lying in the plane o the longitudinal axes of the legs of the staple, said projections adapted to bend the legs inwardly, in the plane thereof, when the sta le is driven.
