5 I claim as my invention:

A staple comprising a driving head p'rovided with a striking portion and side surfaces converging from the periphery of the driving head toward the striking portion;

and legs extending from the driving head in a spaced relation to each other, the striking portion ofthe driving head being aligned With the spacing between the legs, each leg being somewhat flattened and on its inside provided with converging surfaces forming a wedge, and each leg'also having a pointed end bent outward, as, and for the'purpose, set forth, the whole staple presenting a general cylindrical shape.
