SPECIPICATIO Nforming part of Letters Patent No. 374,070, dated November 29, 1887.

Application filed September 1, 1887. Serial No. 248,521. (No model.)

To all whom it may concern.-

- Be it known that I, THEODORE R. HOFF- MAN, of Cleveland, in the county of (luyahoga and State of Ohio, have invented certain new and useful Improvements in Paper-Fasteners;

and I do hereby declare the following to be a full, clear, and, exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in paper-fasteners; and it consists in a fastener which is made of light sheet metal, and which has a perforated head formed upon one end,

the other end being sharpened or pointedyso as to pass through the paper, and then have its end passed through the perforated head and clinched, as will be more fully described hereinafter. V

' The object of my invention is to provide a paper-fastener which is provided with a head or shoulders upon opposite edges, so as to form a guide to prevent the paper from tearing While being handled.

Figure 1 is a plan View of a paper-fastener embodying my invention. Fig. 2 shows the manner of fasteningthe heads together after the fastener has been applied to the paper.

A represents the fastener, which is made of light sheet metal, and which has a suitable Opening, B, formed through one end.- Upon each side of this perforation a shoulder or extension, 0, extends outward at right angles to the length of the fastener for the purpose of forming a head, which, by bearing against the paper, prevents it from tearing while being handled after the fastener has been applied. From near the center of the fastener the oppo site edges of the met-a1 are cut away, so as to form a sharp point, D, which willpass readily I through the paper or through a hole which has been formed through the paper by means of any sharpinstrumcnt.

In applying the fastener to the paper either a hole'is first punched through the paper or cutting a hole until the two shoulders rest against the paper. then turned up over the edge of the paper and the perforated head is bent at right angles, so as to meet the sharp point. The point is passed through the opening in thehcad, and then the two parts are clinched down in the manner shown.

Where a fastener is made which has no eX-' tended shoulders upon opposite edges, the paper is not properly supported at that ,point where the greatest strain comes upon it while ing 13 after having been forced through the paper, the shoulders serving .to compress the sheets of paper together, substantially as shown.

In testimony whereof I affix my signature in presence of two witnesses.

I THEODORE It. HOFFMAN.
