Against the side of the plate II a third plate
or strip I4 is secured by one of the rivets I la, and
this plate or strip is arched outwardly at Ida to
provide a spring arm, which is reduced at Mb to
increase its resiliency. This spring arm is formed
with a diagonal terminal ?nger Mc, which pro

by the rivets 2| to the side ‘I, so that the side
longitudinal edges of both plates will project
laterally of the bar 5, as in the case of the plates
