<p>IN THE CANADIAN PATENT OFFICE Application for Patent and Offer of Disclosure for Public Dissemination Inventor: Robert M. Stepanek Owner: Pettibone Corppration Title: CAPS FOR HAMMERMILL ROTORS SECURED BY NON-PROTRUDING INDIVIDUALLY-REMOVABIE PIN ASSEMBLIES Leading edges of rotor plates which carry the swing hammers of hammermills are protected from wear by removable caps, each secured by paired-pin assemblies. Each pin assembly includes a pair of tubular pins which may be axially abutting one another. During rotor operation, each pin assembly is reliably secure in a pinning position without protrusion into the space between the caps in which the hammers swing. For removal of a cap, the paired pins may be separated, and each part maneuvered to permit the cap to be slipped off, without removal of the rotor or its rotor plates. In the illustrated form, the two pins are secured together by a tie bolt through them and countersunk into the pins; and the pins have heads on one end countersunk into the side wall of the cap.</p> |
