FASTEJING DEVICE.

Application filed hiareh 29 v. wise- Be it known that 1, JAMES comm, a citizen of the United States and a resident of Fulton, in the county of and State of New York, have invented a certain new and useful Fastening Device, of which the following is a specification.

The invention relates to fastening devices, particularly of the type which include a pair of opposed jaws or members connectedat one end and adapted to be clamped over the sheets of paper or other material which are to be fastened together and has for its object to provide a fastening device of this type in which the jaws fold relatively to the connecting member along independent lines spaced from each other to provide a relat-ively wide bend for the accommodation of said sheets without causing said jaws to diverge toward their free ends. Other ob jects of the invention will appear from the description hereinafterand the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawings which illustrate examples of the invention without defining its limits and in which Figure 1 is a plan view ofone form of my fastener; Fig. 2 is an elevation thereof; Fig. 3 is a sectional view through the fastener, sheets of paperbeing shown as held by the fastener; Fig. 4 is a perspective view of the fastener; Figs. 5 and 6 are perspective views of other forms of my fastener; Figs. 7, 8 and 9 are blanks of the fastener shown in Figs. 1, 5 and 6; and Fig. 10 is a perspective View of the preferred form of fastener.

This fastening device comprises generally, two members or jaws which face each other and extend in the same direction from an end member whereby said jaws are con nected at one end, the other or free ends of said members being compressible toward each other, and the jaws or members being connected to the end member in such a manner that each folds along its own folding line relatively to the end member; that is,

the jaws fold relatively to the end member along independent substantially parallel lines spaced from each other One of the members or jaws is preferably provided with a punch or prong projecting toward the other, in which case the other jaw or member has a perforation for receiving the punch or pron Oswego 1921. Serial No. 456,765.

The fastening device or fastener, as devices of this character are generally known, is preferably stamped or struck up from a sheetmetal blank 1 to form the jaws or membersQ, 3 which face each other and extend in the same direction from an end member {i whereby said jaws are connected at one end, the jawsbeing foldable relatively to said end member along independent lines 5; 6 respectively, said

lines

5 and 6 being spaced apart in substantially parallel relation, as shown in the drawings.

In order to automatically predetermine or define these

folding lines

5,, 6 the fastener may be weakened along parallel lines at the bases of the

jaws

2, 3, that is, at the junc notches 9 in the edges of the fastener lnear' said part; in Figs. 6 and 9, the folding lines are defined by corresponding recesses in the form of V shaped notches l0located in pairs at opposite edges of said fastener. In any case, what may be termed a folding bar is provided upon which the jaws are positively I and automatically bent- It will be understoodthat the above are only examples and that the device may beconstructed in any other suitable manner whereby the folding lines are defined in the predetermined manner. By reason of the two lines of

fold

5, 6, a relatively wide bend is provided so that when thefastener is attached to sheets of paper or other material, thejaws will either lie parallel or converge toward each other instead of diverging from each other, as is the case with existing structures in which the jaws are directly connected at one end without the interposition of an end member or the like. Thus, when a number of bunches of'paper, each secured together by fasteners of the herein described construction, are lying one upon the other, the papers of one bunch will not catch in the fastener of another bunch. In other words, the jaws of the fastener lie smoothly or flatwise on th paper. One of the jaws,

preferably stamped therefrom and which forcing the same out of registry spond in shape to that of the prong l1 and,

thus,as shown in Figs. 1 to 9 inclusive, may be in the form of an elongated slot or rectangular opening to acconnnodate the fiat prong 11 of the illustratedexample. lln such case, the slot or openingextends trans? yersely oi the space enclosed by the rib 13 and provides at least one web 1-1 within said rib 13, over which web thepoint of the punch or prong 11 may be clinched, it de sired. The raised rib 13 is preferably areshaped in cross-section although this is not essential, it being understood that said rib may be omitted if desired. .Vhen the rib 13 is interrupted as shown in Fig. 10 a web is provided'between adjacent ends of the interrupted web, over which web the prong may be clinched as described above.

Because provision is made in the improved fastener to define predetermined folding lineswhich are spaced from each other, the jaws or

members

2 and 3 may be bent relatively to the end member 4: without material etl'ort, lVhen so bent, a relatively wide bend is provided in which a maximum number of sheets may be accommodated without *ith each other and without causing the

jaws

2 and 3 to diverge outwardly toward the.r tree ends.

The fastener is economical and easy to produce, is easily applied to a plurality of sheets or detached therefrom and in its operresent? trom sheet metal cesses spaced apart to define parallel, spaced bending lines onwhich'said jaws automatic ally bend relatively to said end member into opposed, spaced relation to each other, and a punch carried by one of said jaws.

2. A. fastener struck up from sheet metal and consisting of an end member, jaws com prising integral extensions of said end memher, said fastener being formed with closed recesses located entirely within the confines :01? the fastener and spaced apart to define parallel, spaced bending lines on which said jaws automatically bend relatively to said end member into opposed, spaced relation to each other, one of said jaws being provided with an aperture, a raised rib on said jaw following the periphery of said aperture, and a punch on the other aw adapted to enter said aperture.

3. A fastener struck up from sheet metal and comprising connected jaws, one of which is provided with an opening, an interrupted raised rib on said jaw and extending about said opening to forma web between its adjacent ends and a prong on the other jaw adapted to be projected through said opening and clinched over said web;

In testimony whereof-I havehereunto set my hand.
