Abstract
Abstract Side frames supporting mechanisms of a machine are provided with lugs for plug-in insertion into slots in a base housing for the machine which form the sole connection to the side frames. The base housing slots and the lugs on the side frames are so located as to provide side to side and front to back rigidity. Resilient material between the lugs and slots serve to frictionally clamp and secure the connections. The base housing includes detent structure to removably secure a cover housing to the base housing.
