FASTENER FOR PAPER BAGS A-ND THE LIKE.

Specification of Letters Patent. Applicatlonfiled November 20, 1911. Serial No. 661.858.

Patented July 29, 1 913.

To all whom it may concern,

Be itknown that I, ALAnaa TRAUB, a

residing at Vienna, Austria-Hungary, have invented new and useful Im irovements m Fasteners for Paper Bags an the Like, of

which the following is a specification.

The present invention relates to a fastener for-holding loose sheets of paper and the like parallel to the edge seized or to the folded edge seized, which fastener is particularly adapted forsecuring the closure of paper bags, and will form a'reliable link for fitting a carrier,' for instance for carrying the thus closed paper bag, or may be made to serve itself asa carrier.

The accompanying drawings illustrate several constructional 'forms of the invention and the manner it is employed.

Figure 1 illustrates oneform of the device. Fig. 2 illustratesa second form. Fig.

2* illustrates a third form. Fig. 3 illustrates a fourth form. Figs. 4 to 12 inclusive illustrate" diagrammatically the manner of applying the fastener to the paper. Fig. 13 illustrates a perspective View of a fifth form of the device.

In the constructional form according to Fig. l the fastener consists of a piece of sheet metal drawn in form of a J, the longer leg 1 of which has its sides inwardly tapered to form two notches 2 in its sides, so that it can be easily folded over the short leg 3. The edge of the short leg is slightly hollowed out, so that points 4 are produced at the corners,which points will enter into the paper and thereby facilitate the securehold of the fastener. For the same purpose the edge is besides. preferably provided with prongs or the like. This may also be the case with the edge of the long leg 1.

Fig. 2 illustrates another modification, in which the bending over is facilitated by the sheet metal being perforated at the place Where it is to be bent over. Both the edge of the long and thatof the short leg are serrated. The serrations and the edge of-the short leg are so arranged, that-when the fastoner is bent over. these serrations will penetrate through the paper into holes provided in the metal. The grip of the fastener on the paper is thereby greatly increased. In

Here the short 1e and the lower part of thelong leg are provided up to the bending line with corrugations, which extend beyond the joint between the two legs. The corrugations are impressed either during. or after the bending into sha e of the two legs, preterably by the suita ly shaped die, .which prmluces the bend, impressing the corrugations into the bent bend with a last pressure. These corrugations need, of course, not extend as far as the edge of the legs.

Fig. 3 is a constructional form, according to which the fastener consists of a wire frame likewise bent into the shape of a J.

Paper bags and the like are closed by means of the hereinbefore described fast eners in the following manner: The edges of the mouth of the bag are laid together and introduced between the legs of the fastener (Fig. 4.) Now the edges of the paper are folded over the edge of the short leg. This can be done in an easy and quick manner by the fastener being turned in the direction of the arrow, Fig. 4, until it has the position in Fig. 5. Then the long leg is bent over the short one in the direction of the arrow in Fig. 5, whereby the closure is completed, Fig. 6. If a carrier is to be combined with the fastener, a carrier ring 6 may be inserted as shown in Fig. 6. Tu place of this ring of course also a loop or the like may be em-- ployed. The weight of the parcel will produce so great a friction between the paper and the edge 7 of the short leg, that the edge of the bag will be securely held be tween the legs, which will be further as-' sisteddiy the action of the points 4. The

component P, Fig. 6, of the weight of the parcel will also produce a friction at the edges 8 and 9 of the bent over-fastener, so that there will be no fear of the edges of the paper slipping out of the fastener.

It will be of advantage to. first fold over the edge of the bag before the fastener is fitted, as this will increase the friction and strengthen the closure. The Figs. 7, 8 and 9 illustrate the operations in making the closure. It will be still better to fold over --paper bags to be closed but to. their comwhich may be bent over a s bag are in the finished closure prevented by the double paper from tearing sharp edge 10, Figs. 11 and 12.

In the modes of use in Figs. 7 to 12'the fastener is applied not to the edge of the at the Inon fold.

In the constructional form shown in Fig. 13 the fastener is formed so as to serve at the same time as a carrier for the paper bag closed with the fastener. The fastener is in this case preferably stamped of an endless band of sheet metal so that the edges 1 and 13, at which the piece of metal is cut off from the whole band are of a congruent curvature, so that the several pieces are stamped out of the whole without any waste. The piece of metal is then bent in the J- shape the same as with the hereinbefore described constructional forms. The portion 14 has a cut 11 made in it by means of which out there is formed a long leg portion 12 ort leg 13 in the manner hereinbefore described. The remaining or marginal part of the portion 14 which is not bent over will form a sort of loop or carrier, by which the sheets of paper, the bag or the like, to which the fastener has been fitted, may be conveniently carried.

The edges of the cut 11 are preferably headed over, so as to remove thesharp edge which would be inconveniently felt in carrying the parcel.

The essential feature common to all the hereinbefore described constructional forms .consists in that the papers to be united or carried are gripped by a fold made over a sharp edge and held by the friction produced thereby. This is above all obtained by means of the short leg of the fastener,

. against the upper edge of which the paper is drawn the tighter, the greater the load. The bending over of the upper ton ue is of less importance for obtaining this e ect; the tongue serves chiefly for the attachment of the carrier and is indeed of great importancein consequence of the simple and safe mannerof the attachment enabled thereby.

Claims: I 1. A combined fastener and carrier for paper bags and the like, ccnsisting of a flat piece of metal bent intothe shape'of a J to form 'a pocket adapted to receive the edges of the mouth of a paper bag, a part of the long leg thereof being adapted to be bent over the paper to clamp the same between said part of the long leg and the short leg, the sides of said part being inwardly tapered at the bending line? the edge of the shortleg of said piece. 0 metal opposite to the bending line having a concave curvature and terminating in points.

2. A combined fastener and carrier for paper bags and. the like consisting of a piece of sheet metal bent in the shape of a J to form a pocket, the long. portion of said of sheet metal' bent'in the shape of a J p to form a pocket, the long portion of said piece of sheet metal having a U-shaped '1ncision forming a portion, adaptedto be bent over the ed e of the paper to be introduced into the pociet formed by said piece of sheet metal, the remaining part of said long portion forming a carrier, the uppered e. of the short leg of said piece of sheet meta having a concave curvature and terminating at the corners in points.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
