J.-, assignor to Stapling Machines 00., a corporation of Del aware Application March 27, 1937, vSerial No. 133,294‘ 8 Claims. (Cl. 140—93) This invention relates to box. making machin ery and particularly to machines for equipping wired box parts with fastening means. It is an object of the invention to provide a 5 machine of the type shown in U. S. Patents Nos. 1,933,031 and 2,024,188, with mechanisms which will permit it to operate on di?erent types of box blanks and particularly upon ?breboard box blanks having an overlapping ?ap at the closing 10 corner edge of the completed box. One illustrative embodiment of the invention is shown in the accompanying drawings, in which: Figure 1 is a perspective View of one type of 15 box blank upon. which the mechanism of this invention is adapted to operate. 1 Fig. 2 is a perspective view of a completed box made from the box blank shown in Fig. 1 and showing the overlapping flap at‘ the closing cor 20 net of the box. Fig. 3 is a side elevation of a fastener supply ing machine equipped with the mechanism of this invention. Certain parts are omitted for clearness of illustration. 25 Fig. 4 is a plan view of the machine shown in Fig. 3 with certain parts omitted for clearness of illustration. Fig. 5 is an enlarged side elevation of a por tion of the machine of Fig. 3 and showing a box 30 blank being fed into the machine in the direc tion of the arrow. Fig. 6 is a similar view on a still larger scale showing the position of the parts just prior to ?breboard. While a single sheet of side material is shown in the illustrative box blank, it will be understood that a plurality of sheets may be used. The wires C are stapled to the box parts in a box blank machine such, for example, as the 5 machine shown‘ in U. S. Patent No. 1,669,383 of May 8, 1928. When the box blanks emerge from the box blank machine they are connected to gether by the wires $3, appropriate spaces being left between succeeding 'box blanks to permit .10 severing the wires between blanks and forming the fasteners D thereon. The machine of this application receives the wire-connected box blanks, severs the wires be tween the blanks, forms prongs on the wire ends, 15 - bends the wires to form the bights D, and drives the prongs into the box parts to perpetuate the bights D. Referring to Figs. 1 and 2, the box blanks to be operated upon are fed into: the machine onto 20 a table T which is reciprocated vertically to pre sent the wires to the fastener supplying mecha nism in the manner fully described in my Pat ent No. 1,933,031. ‘ The box blanks are positioned on the table T IO 5 on stock supports I and are held against vertical movement by presser bars 2. When the wire connected box blanks have been correctly posi tioned for a fastener supplying operation the machine is started and one cycle of operation severs all of the wires and forms bightsthereon, all as fully described in said Patents Nos. 1,933,031 and 2,024,188. 0 . position of the parts during subsequent stages of a fastener supplying operation. In Fig.3 is shown‘- .generally the cutter-operé ating mechanism '3 which operates ?rst to sever up5 the wires between blanks. Spindles‘ 4 thereupon bend the wires to form the bights and'driving In Fig. 1 is shown one type of box blank which has been equipped with fastening means by the 40 machine of this invention. As there shown, the ing cross bars 6 thereupon drive the wire ends into the box parts to perpetuate the bights. 40 a fastener supplying operation. ' 35 Figs. 7 and 8 are similar views showing the mechanism 5 operatedv by vertically reciprocat The wire-cutting, bight-forming and driving blank consists of a single sheet of bendable side material A creased at potential box corners and mechanisms are fully described in said Patents cleats B connected together by binding Wires C stapled to the box parts. The ends of the bind 45 ing wires have been bent and driven into the Nos. 1,933,031 and 2,024,188, and need not be described in detail herein. When box blanks having an extending ?ap E side material A to form bights D. The side ma terial A of the right hand end‘ of the blank which constitutes the top of the box when the blank is folded into box form is provided with an ex 50 tension or ?ap E which, as shown in Fig. 2, is bent down over the front side of the box when the blank is folded into box form. The cleats‘ B are usually made of resawed lumber while the side material A is made prefer such as that shown in Fig. 1 are operated upon in the machine the ?ap E in its extended position would interfere with the formation of bights D at that end of the blank. The present invention provides mechanism for bending the ?ap E down- 50 wardly prior to and during a fastener supplying 55 ably of bendable material such, for example, as As best shown in Fig. 5, the box blank is fed 55 operation to permit the bight-forming mecha ni'sm to engage and operate on the wire which extends over the flap. 2 2,131,971 restores rod 8 and ?ngers ‘I to their initial position for engagement of the ?ngers ‘I with the ?ap at into the machine with the ?ap E at the rear end of the blank.

Each rod 8 is pivoted to an arm 9 ?xed to a rock shaft ID journaled in the rear end of the next box blank.
