ABSTRACT:
A pin mounted on the under side of a turntable is used to hold a drive belt also engaged by a drum which is mounted on the turntable and forms a loop. Mounted on a base plate is a drive pulley. This invention solves the problem of how to assemble the turntable on the base plate and end up with the belt engaged on the pulley and the drum. During assembly the turntable is placed over the base plate with the pulley inside the loop. A simple turning of the turntable will cause the belt to tension and slip off the pin onto the pulley.
