IMPROVEMENT IN PAPER-FASTENERS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM M. TrLnsroN, of New York, county of NewYork, and State of New York,

have inventedcertain new and useful Improvements in Paper-Fasteners; and Ido hereby declare the following to bcafull, clear, and exact description of the same, reference being had to the'accempanying drawing, making a. part of this specitication, in whichi i Figure 1 is a perspective view of my fastener.

Figure 2 is a view of the fastener struck out before being formed up.

Figure 3 is a top plan View after being formed up.

Figure 4 is a side view of same.

Figure 5 is a sectional view of the fastener applied to use.

Similar letters of reference denote corresponding parts in all the figures.

My invention relates to certain improvements in paper-fasteners, whereby I am enabled te make the fastener serve as its own punch, and thus do away with the expensive machines heretofore used for punching the holes preparatory to fastening the paper together.

To enable others skilled inthe art to make and use my invention, I will proceed to describe the same.

In making my fastener, I first strike out, vof sheet brass or other metal, a piece, A, as shown in fig. 2, having on each end a short arm or lip, @and having on its exterior long arms, a a, punched loose on three sides, as also shown in iig. 2.

After being struck up, (or bythe same operation,)I fiuto or groov'eeach and all of the arms to render them stili'. These arms are then bent at right angles to the main body of the fastcnergvhcn it is ready for use.

4In fasteners, as heretofore constructed, one great objection has been that, being made of thin Aflat metal, they would not bear the strain of being forced through more than a few thicknesses of paper, hence the necessity of having a separate machine for inserting the fasteners, which is not only expensive, buta slow and tedious operation where there are a number to be' inserted lat one time. But, in my improved fastener, the

arms or points being stii, they may he quickly and easily inserted with-the fingers, and thc ends bent down.

As will be seen in tig. 5, the long arms are bent down after the fastener is inserted, and the short arms bent down or lapped" over them, the grooving in point a coming under that of point b, thus preventing the points from being caught in anything and becoming unbent and loosened, as is common in others.

It is obvious that the fastener may be made of any length, and that for strength there may be any suitable number of the intermediate arms. It is also obvious -that my principle of iuting may be applied to any other forms of fasteners having points to penetrate the paper. 1

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is

Corrugating, Huizing, or grooving the points and arms, for punching thc holes as` described.
