4 a similar view, showing the application of the staples to the fastening of wires to hedgeplants:

Similar letters of reference inditate the same parts.

The object of this invention is to improve the means for fastening barbed wires and other wires to posts, hedge-plants, 85c in the man- 'ufacturc of fences, and for other similar purposes. 1 r

The invention consists in a new form of staple or double-pointed nail adapted to straddle the wire and bind it securely to the post or other support.

The invention may be more particularly described as follows, referring by way of illustration to the drawings. 1 take a fiat plate of steel or other suitable metal, of substantially uniform thickness and sufficient strength to drive into hard wood and to stand the heavy blow requisite therefor, andout of it I cut the nails in the form shown in Figs. 1, 2, using any suitable punch or die for such purpose. The nail A thus formed has two sharp points, a a, substantially in line with its lateral edges. From each point it bevels inward and backward to the inner end of the slot at a, the bevel being either a curved line or an angular line, a d a, as shown, the latter being preferred. The inner end of the slot may be rounded orcut square across, preferably the former, to fit the wire, and it is made of less diameter than the wire so as to bite into the latter whendriven home, and thus hold the wire as securely as possible against longitudinal movement. The bevel of the innmlines of the prongs causes the wood to force both prongs outward or apart as the nail is driven, thereby insuring a stronger hold in the wood and less liability of accidentally drawing out. Sufficient; metal a is left at the head if the nail to prevent its splitting-and to suslai-u the heavy blow requisite for driving it into hard wood and into the metal of the wire.

The manufacture of the staples from plate metal renders their edges thin, enabling them to cut and penetrate easily, and preventing them from splitting the hedge-plants, while the width of the prongs and head gives them thestrengthnecessaryfortheirpurposes. S aples made in this way are also adapted to be fed and driven by a machine, which greatly facilitates the operation. 1

I have used these staples in the m mnt'ac- WESLEY You) G.
