ABSTRACT:
A hinge-pin for coupling two rows of belt-fasteners mounted to the ends of a belt-conveyor or the like is constituted by a series of metallic elements fitted in succession around a flexible axial core. Each element has the approximate shape of a semi-cylindrical rod and carries two projecting lugs at each end. These elements are placed on each side of the flexible core in two inverted rows and in staggered relation from one row to the next. The projecting lugs of both ends of each element are engaged in corresponding cavities of the opposite elements of the other row. The different elements disposed in succession are thus interengaged in the axial direction with a possibility of limited displacement of the elements in the other directions, thus endowing the hinge-pin with the requisite flexibility.
