Abstract
818,263. Making bolts; making connectors for electric cables. BURNDY CORPORATION, [formerly BURNDY ENGINEERING CO. Inc.]. April 24, 1956 [May 2, 1955], No. 12452/56. Class 83 (2). [Also in Group XXV] A method of making a slotted bolt having a head portion 12, Fig. 9, and two legs 14 defining a slot 38 therebetween, comprises cutting a blank 10c, Fig. 2, from a length of flat metal stock, laterally pressing the two end portions thereof to form a blank having reduced end portions 14c and an enlarged intermediate portion 12c, swaging a plurality of transverse grooves 20, 28, 30, Fig. 4, in the intermediate portion and simultaneously forming the end portions 14 each with a part-cylindrical surface on one side and a flat surface on the other side, bending the blank to U-shape and providing a screw thread 42 on the part-cylindrical surfaces of the legs for receiving a nut 44. The end portions 14c are pressed between dies in a coldforging machine. The bolt is preferably for use in clamping together two electric cables between the inside surface 40 and an insert 46 slidable between the legs 14 upon rotation of the nut.
