STAPLE.

To all whom it may concern:

Be it known that I, FRANKLIN R. WVHITE, a citizen of the United States, and a resident of Waterbury, in the county of New Haven and State of Connecticut, have made and invented certain new and useful Improvements in Staples, of which the following is a specification.

My invention relates to an improvement in staples, and more particularly to that kind or class thereof which are formed from blanks cut or punched from sheet metal, and has for its object to produce an article of this kind which will be cheap to manufacture, strong and durable, which will have a comparatively large head, and which will be capable ofuse as a button fastener, or for any other purpose or purposes for which similar articles are now employed.

With this and other ends in view, the invention consists in certain novel features of construction, as will be hereinafter fully described and pointed out in the claims.

Inthe accompanying drawings, Figure l is a plan view of a blank from which the sta- Fig. 2 is a plan view of the staple in its first stage of formation. Fig. 3 is a plan view of the staple in its next stage of formation. Fig. 4 is a view in elevation of the staple as shown in Fig. 3. Fig. 5 is a sectional view taken on the line 55 of Fig. 3, and Fig. -6 is a view in elevation of the finished staple.

In the accompanying drawing Fig. 1 shows a blank which may be cut or punched from sheet metal, and from which the staple is to be made, said blank comprising an elongated curved body portion A and pointed end portions B extending therefrom in the direction of its greatest length.

In constructing the staple I first subject the blank shown in Fig. 1 to the action of a shearing punch, by means of which inwardly extending cuts are formed in the blank at both sides of the pointed end portions B, the

Specification of Letters Patent.

cuts at each end of the blank being substantially parallel and extending toward the center a suitable distance, and by the same operation the metal strips which are thus formed, are bent at substantially right angles to the body portion of the blank, as clearly shown in Fig. 2. At the next stage of the formation of the staple the portions E at each end of the body portion, are bent or forced towards each other by any suitable means until the edges F thereof meet, as indioated in Fig. 3, thereby forming a round or circular head. The next, and final operation, consists in subjecting the prongs D to pressure by any suitable means, whereby they are given a rounded shape, as shown in Fig. 6, points being formed at their extreme ends at the same time, thereby completing the article.

It will be seen that I have constructed a staple formed of one piece of metal, which will be cheap to manufacture, which has a comparatively large head, and which will be strong and capable of use for all purposes for which similar staples are em loyed.

If desired, the head may e covered with cloth or any other suitable fabric, thus adding to the finished appearance of the article.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

A staple, comprising a head, and prongs extending at an angle therefrom, portlons of the metal forming said head being bent back of the bases of said prongs, thereby imparting to said head a rounded or circular shape, substantially as described.

Signed at Waterbury, in the county of New Haven and State of Connecticut, this 24th day of June, A. D. 1907.
