ABSTRACT:
A mounting for quickly removing and replacing cutter teeth on a rotary drum includes a cutter tooth socket mating with a socket housing defining a tapered channel having a base surface and a lateral surfaces inclined with respect to the longitudinal axis of the tapered channel and oriented at an acute angle with respect to the base surface to retain the cutter tooth socket by a wedging action. The cutter tooth socket is also retained on the socket housing by a spring retainer seated in a recess in the base surface and engaging a protrusion depending in a groove defined by the cutter tooth socket. A leading side of the cutter tooth socket with respect to the direction of cutter movement contains oblique surfaces to cam to the side the material of the surface being cut. A dummy cap is inserted in socket housings from which the cutter teeth sockets have been removed and extends beyond the socket housings toward the surface being cut to protect the socket housings from wear by the work surface.
