Abstract
388,917. Stapling. POLLAK, J. E., 20, Holborn, London.-(Brehmer, Geb.; Plagwitz, Leipsic, Germany.) Jan. 28, 1932, No. 2629. [Class 89 (iii).] A machine for forming and inserting, for example into the corners of boxes, wire angle or corner clamps or staples, includes a member adapted to support the bridge of the staple during driving and to co-operate with throat members to form closed channels for the staple legs, and relatively moving driving members so arranged as to engage the whole of the staple bridge while the latter is being bent to angular form during driving of the staple. The stapling head is adjustable laterally and vertically to suit the work, and vertical adjustment of the head is arranged to control automatically the length of staple wire fed to the head. The stapling head 10, Fig. 15, is vertically adjustable, by means of a hand-wheel 15, in a guide member 11 which is mounted, by means of links 14, for lateral adjustment on brackets 13. The main driving shaft 22 is formed in universally-jointed sections. The head 10 carries a cam surface 17, Fig. 1, which engages a screw 18 in the wire-feed lever 19. Hence, vertical adjustment of the head varies, correspondingly, the length of wire feed. The wire is fed into a slot in an inside former 24, Fig. 2, when the latter is in its inoperative position. The stapling head comprises a driver bar 30 operating in a guide 32, a bifurcated outside former 29, a staple-supporting member 59, and curved throat members 44, 45, Fig. 6, having slots to receive the staple legs. The member 59, Fig. 12, comprises limbs which extend forwardly and downwardly beneath the driver, the upper surfaces of the limbs being shaped to support the staple bridge during all stages of its bending and driving. The outer surfaces of the limbs are curved to co-operate with the throat members 44, 45 in forming closed channels for the staple legs. Normally, springs 62 hold the member 59 forwardly in a guide block 33 which is mounted to slide vertically in the head 10. Two driver members 47, Figs. 6 and 12, are mounted by a common pivot 50 in a recess in the driver guide, and are connected by links 54 to the driver bar 30. They are so shaped and mounted as to maintain contact with the whole of the staple bridge during its bending and driving. The shaft 22 carries cams 28, 27, 26, Fig. 2, for actuating respectively the wire-feed lever, the outside former, and the driver and driver guide. In operation, the driver guide being raised and the former 24, carrying a length of wire, having been moved into operative position by its spring 57, the former 29 is lowered by the cam 27 and roll 35 to bend down the staple legs. The cam 26 then lowers the driver guide 32 by means of a roll 39, bringing the driver members 47 into contact with the staple bridge and the block 33 into engagement with the work, and also swinging out the former 24 by means of a cam surface 32g. The cam 26, acting through a wrist pin 41 and cam slot 43, then lowers the driver 30. The members 47 first force the staple legs into the curved throat members 44, 45 and then into the work, Fig. 6, at the same time rocking about their pivot 50 to bend the staple bridge to angular form. During this driving operation, the staple bridge and legs are continuously supported by the member 59 which is, however, progressively withdrawn by the pressure of the driver members on its downwardly - inclined surfaces. Finally, a clincher C, Fig. 6, is raised to bend over the staple legs, the cam groove 43 being shaped to cause the driving members to dwell in their lowest position during clinching.
