SHEET-METAL Application filed July 24,
To all 0.0/1.0271- it may concern:
Be it known that I, SIDMAN Rnsmu, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sheet-Metal Fasteners, of which the following is a specification.
My invention relates to sheet metal fasteners intended to serve as a means for term porariiy attaching together and holding i a group a number of separate loose sheets of paper, or similar articles. The object of my invention is to provide a simple, serviceable article of this kind which may be cheaply manufactured, having an attractive appearance and with its engaging member so formed and constructed as to facilitate its a plication to a group of papers, and which will hold the papers securely and be higl'ily desirable and useful for the purposes for which it was designe l. My invention resides in the particular form and construc tion of the parts of the fastener, and more particularly in the arcuate flared shape of the end of its tongue portion, as hereinafter described and as more particularly pointed out in the appended claims.
in the accompanying drawing, Figure 1 a front or face view of my improved fastener; Fig. is asection the same on the line 22 of Fig. 1; and Fig. 3 is a rear view of the fastener, showingin dotted lines the position in which the edge of a group of papers is presented to the tongue member in applying the fastener to them.
My novel fastener or paper clip is formed of sheet metal possessing a considerable degree of inherent elasticity such as sheet brass, and comprises a flat front or body portion .i, which may coin'eniently be of the oral shape illustrated. and which forms a field which may he stamped in has relief with a design or emblem of any desired and snitahlc character, such as a trade mark 1920. Serial No. 398,796.
or advertising device or emblem, and which may he colored by the application of enamel, or plated, or otherwise decorated as desired. Connected to the top edge of the portion A is an integral tongue B which is folded from an open loop of the portion A, and the end C of which is flared outwardly from an arouate bead D near the end of the tongue contacting the contiguous rear surface of the part A near its lower edge. The curved and flared shape of the end of the tongue is the characteristic and essential feature of my invention, and renders it very easy to apply the clip to a group of papers when the edge of the group is applied to an intern'iediate point in the curve, as indicated by the dotted line E in Figure 3-thus en abling a coniparatively stiff clip to be applied to a comparatively thin bundle of sheets without tearing them. My improved fastener is therefore particularly secure and serviccahle, as well as highly'attractive and desirable as an advertising novelty.
l claim I l. is an article of manufacture, a fastener formed of elastic sheet metal and comprising a flat front portion and backwardly folded integral engagii'ig tongue, the end of said tongue being outwardly flared along an arc uate path.
2. an article manufacture, a fastener formed of elastic sheet metal and com prising a relatively broad flat front portion and a backwardly folded integral tongue connected with a said front portion by an open loop, the end of said tongue being outwardly flared along an arcuate path.
3. As an article of manufacture, a fastener formed of elastic sheet metal and com prising a front portion and a backwardly folded integral engaging t0ngue,said tongue being formed adjacent its end with a t 'ansverse arcuate bead and its end flared outwardly from said head.
