Abstract: A cooperative plurality of energy-dissipating means is incorporated into a high-speed mechanism so as to be sequentially activated and be operative upon a working member for timely extraction of precise quantities of excess kinetic energy and for producing long life and bounce-free fast operation of the working member. Incorporation of the invention into a high-speed printer wherein energy absorption from components of the printer is accomplished via structurally improved members is also disclosed.

Abstract: A resilient nonmetallic printer hammer made of composite material and having relatively large size and small mass is disclosed. The hammer employs a frontal insert member for printing contact and a rearward insert for energy dissipation and driving. An attached spring assists in hammer retraction and in frictional dissipation against a mating member at the rearward face.
