Abstract

Shown are several types of single piece flexible hammer elements with various bends formed in the horizontal base portion as well as the vertical stem section to eliminate the sliding component of motion during deflection of the hammer element and at the time of striking the stator post of a holding magnet. It is desirable to eliminate this sliding component in order to minimize wear.

One Piece Hammer Element for Ultra Wide Multiple Print Position Hammer

Shown are several types of single piece flexible hammer elements with various bends formed in the horizontal base portion as well as the vertical stem section to eliminate the sliding component of motion during deflection of the hammer element and at the time of striking the stator post of a holding magnet. It is desirable to eliminate this sliding component in order to minimize wear.

As seen in Fig. 1, flexible hammer element 10 has spaced legs 11 with vertical tips 12 attached to the magnetic core 13 by screws 14. Permanent holding magnet 17 is bonded to pole 16 of magnetic core 13. In Fig. 2, legs 11 form a horizontal base 15 extending under pole 16 and around permanent holding magnet 17. Vertical stem 18, which is bent near segment 19, forms a 90- degree angle 20 with the axis of stator post 21 which is wound with a release coil
22. Fig. 3 shows another configuration which accomplishes the same zero component of sliding motion of the segment 19 of stem 18 at the point of impact with stator post 21 when retracted from the forwardmost impact position by the attraction of permanent holding magnet 17.
