Abstract
177,471. Evans, T. Dec. 24,1920. Angular bending ; formers.-In a device for doubling tin plates, the plates are held down along the line of bending by a lever which is adapted to be automatically released at a given point in the doubling operation. The plates are placed on flaps 1, 2 the former being fixed and the latter mounted on the diametral plane of a quadrant-shaped shaft 3 which is cam-driven through a sector 34 and clutch 32. The plates are registered lengthways bv studs 6 mounted in levers 8 hand-operated through the linkage 11, 12, and transversely by a fixed abutment 13 and a sliding arcuate bar 14 controlled through linkage from the lever 20. To prevent buckling of the plates during doubling, a spring- pressed holding-down lever 23 is initially held in contact with the work by means of a handle 25, till rotation of the shaft causes a concentric fingerpiece 28 thereon, to enter the slot 27. The handle 25 may then be released without motion of the lever 23 ensuing till further rotation of the shaft disengages the finger-piece from the slot. The apparatus is stated to be specially suitable for the process described in Specification 166,935.
