Abstract: 1,039,481. Making staples; shearing; angular bending. FOUNDATION FOR MEDICAL TECHNOLOGY. March 3, 1965, No. 9010/65. Headings B3A, B3E and B3W. Miniature staples for medical use are made from stainless steel, tantalum, or a cobaltchromium alloy wire, by a machine which cuts off a length of wire supplied from a reel, bends the length to U-form, trims the ends of the legs to a sharp point and loads the finished staple into a magazine which has a pocket for each staple. Wire 24 from a reel 23 is fed by a reciprocating gripper to a cutting-off mechanism comprising a pair of punches 51 which each remove a short section from the wire, and which are spaced apart by the length of wire required for each staple. The punches are reciprocated in a stationary die 53 by a lever 48 operated by a cam 47. The reciprocating gripper comprises two jaws 39, Fig. 2 (not shown), biased by springs 41, each pivoted to a body 32 attached to a rod 34 which is reciprocated by a cam 33. The clamping pressure of the jaws is adjusted by a screw 42. Bending.-The middle portion of the cut length of wire spans a passage 56 in the die 53 Fig. 4 (not shown), and is pushed along the passage by a bending punch 62, against an anvil 61, which is raised to block the passage, by an arm 76 operated by a cam 74. The bending punch is operated through a bell crank 86 actuated by a cam 84. Pointing legs.-While the staple is held against the anvil 61 the ends of the legs are sheared at an angle by two square section cutters 67 which reciprocate in bores 68 in the die 53. The cutters are actuated by a lever 71 oscillated by a cam 69. Removing waste.-The clippings from the two shearing operations fall by gravity and are drawn away by a suction pump. Loading into magazines.-After the pointing operation the anvil 61 is retracted and the punch 62 is advanced to push the staple into one of six pockets of a magazine 89 mounted on a horizontal shaft 91. In a modification the magazine is mounted on a vertical shaft, and in a second modification the magazine is designed to receive more than one staple in each pocket. A straight magazine is also described, in two forms, Fig. 14 (not shown), and Fig. 15 (not shown). The magazine is rotated or moved linearly step by step, according to its type by means of a pawl and ratchet mechanism, comprising a cam-operated lever 98 connected to a pawl 99.
