Abstract
A coupling device for railway type "f" according to the standards of the aar, of the type having one end of the rod with a pin hole passing through it, said pin hole being partially defined by two side walls and one concave bearing surface opening towards the longitudinal axis of the pin hole, an upper and a lower curved band, symmetrical with respect to the longitudinal axis of the face and formed on the carrier surface and which are joined to the side walls, characterized by the improvement which comprises that the lower and upper bands are made in the form of a composite curve generated by the radii r3, r2, r1, r2, r3 in this order and where: (a) r1 is a central radius traced from a substantially located point on the longitudinal axis of the cane, in such a way that the arc that it generates is symmetrical with respect to the longitudinal axis; (b) r3 is a lateral radius traced from a point located inside the pin hole, so that the arc it generates is tangent to the side walls, and (o) r2 is a connection radius traced from a point located inside the hole of the pin, in such a way that the arc generated is tangent to the arc generated by rl and r3.
