' WIRE STAPLE.

Specification of Letters Patent.

latented April 27, 1909.

Application filed October 3, 1907. Serial No. 896,769.

To all whom it 11w. concern:

Be it known t at 1, WILLIAM HANSELL PAGE, a citizen of the United States, residing at Philadelphia, in the county of Phila delphia and' State of Penns lvania, have invented a new and useful ire Staple, for which I have not taken out patent in, an country, and of which the following is a full: clear,. and exact description and specification.

The obi'ect of my invention is to provide a wire. step e which shall be readily driven and the prongs of which in the driving shall take curved outward courses, forming two hooks, and creating a clenching engagement with the material into which the staple is driven.

My invention also comprises an improved 'de plate to be used in connection with said staple to facilitate in its driving and also in the efiicient engagement of the wire or rod to be held in place between said staple and Figur 1 is an elevation of my improved c Fig. 2, is a perspective view of the plate adapted to be used therewith. Fig. 3, s' a. rspec'tive view of the staple and p ate m' t e imtlal position just before drivin a section of wire is also shown therewith. %ig. 4. s a similar view, with the parts in final position.

The staple-.5 has itsprongs 6 first convergmg about midway an nearly meeting at 7,

,and then diverging to their extremities 8 in arcs. of. circles of substantially the same diameters. By this construction it is obvious that when the staple is driven the points will follow in directions substantially similar to their outward contour, that is their will contmueto curve first outwardly an then upwardly, substantially as shown by the dotted lines n Fig. 4, forming a most eflicient clench-., mg ment with the wood or other mamto which the staple is driven. Such a structure is particularly wire such as 9 is to be he din position by the sta 1e, since the same may be efiiciently loo ed between the staple 5 andplate 10; 1t being impossible for the staple to be withdrawn from the wood, a perfect grip of the wire is maintained. This is only an example of one of the uses of the staple that cannot in the slightest degree be withdrawn after being driven and clenched as above described.

Theplate 10 is provided withapertures 11 to receive the rongs of the staple, and serves as a guide for t and also to form a vise or look for a body such as the wire 9 between the plate and the staple.

What I claim as my invention is,

1. A staple consistmg of a single strandof wire from the loop of which the prongs incline toward each other until they meet or nearly meet about midway their extensions then diverge with curved equal bend to their extreme end points.

2. A wire staple consisting of a single strand of wire having its prongs converging about midwa their extensions and then (llverging in su stantial arcs of circles to the extreme end points thereof.

3. The combination of a staple consisting of a single strand of wire havmg its prongs convergm about midway their extenslons and then iverging in substantial arcs of circles to the extreme end points thereof, with a metal late having apertures for receiving and gui mg the spread of said prongs. In testimony whereof, I have s name to this specification in the pre two subscribing witnesses.
