Abstract: 541,832. Stapling. EVERY, C. E. (Bohm & Kruse Maschinenfabrik). May 11, 1939, No. 14128. [Class 89 (iii)] In a stapling machine comprising several stapling heads aranged side by side, the staples are shaped with their crossbars perpendicular to the front of the machine, and can be turned, by rotation of the outside formers, so that they are driven with their crossbars parallel to the front of the machine. As shown, three heads 4 are adjustably mounted on a crossbar 3. Each head comprises a cylinder 37, a reciprocable outside former 38, and a driver 46. The former has a slot 40, the lower part of which is vertical and the upper part spiral, engaged by a roller 41 carried by the cylinder, and also has, at its lower end, hardened plates 44 with grooves 45. As the former 38 descends to shape a staple, the plates 44 bend a staple length, previously fed from the rear of the cylinder into a channel 63 therein, over an anvil 53. When the spiral part of the slot 40 engages the roller 41, the former 38 is rotated through an angle of 90 degrees to bring the staple crossbar parallel to the front of the machine. The roller 41 is adjustable to vary the angle through which the staple is turned. The anvil 53 is held immovable, while the staple is is shaped, by an abutment 54 which is released when the staple is driven. The driver slides in the grooves 45 and rotates with the former. The staple is supported internally, during driving, by a member 49 which is pivoted within the former and moves to supporting position, as the former descends, under the control of a spring 51 and cam surface 52. The formers have heads 39 removably and rotatably engaged in a slot 10 in a crosshead 8, and the drivers have headis 47 similarly engaged in a slot 9 in a crosshead 7.
