Self-Aligning Hammer and Magnet Mechanism

This device is a self-aligning hammer and magnet mechanism for use with a bar printer.

It includes a magnet 1 and a hardened steel member 2 fixed adjacent one another. A flat surface is ground across the pole faces of the magnet and the hardened steel member. A hammer 3 is positioned in front of the magnet. The hammer is mounted on a mounting bar 4 by means of slot 5 to produce a floating pivot. The hammer has a flat ground back and a ground radius 6 opposite the slot. The ground radius bears against the flat face of the hardened steel member to permit rotation of the hammer.

A return spring 7 forces the hammer against the magnet such that the two ground surfaces of the hammer and the magnet are forced together to produce a minimum air gap. The hammer mounting prevents vertical movement, but does not prevent the slight horizontal movement required to reduce the air gap.
