Abstract:
A support for the shoe of a guide for a chain drive comprising a base plate adapted to underlie the shoe, said base plate being formed of punched-out metal plate stock having spaced parallel longitudinal edges for supporting the shoe therealong, and a pair of mounting seats connected to one of said longitudinal edges by bend lines parallel to said one longitudinal edge, said longitudinal edge having a shear surface on one surface and a rupture surface on the opposite surface as a result of being punched-out by a punch passing in a given direction from the shear surface of said edge beyond the rupture surface of said edge, one of said pair of seats being bent along its associated bend line in a direction away from said shear surface of said one longitudinal edge, and the other of said seats being bent along its associated bend line in a direction away from said rupture surface of said one longitudinal edge, the bend line of said other seat comprising an end edge positioned between said other seat and said one longitudinal edge, said end edge having a shear surface contiguous to the rupture surface of said one longitudinal edge of the base plate and a rupture surface contiguous to the shear surface of said one longitudinal edge of the plate, produced by a punch passing in a direction opposite to said given direction to thereby produce a different shear and rupture surfaces at the opposite ends of said bend line.
