Abstract:
A perforated finishing barrel assembly including a finishing barrel having a lengthwise extending access opening in one side thereof, and at least one cover fit into said opening, said barrel side having a lengthwise series of tabs formed along said opening and projecting towards said opening, said cover having a series of spaced apart outwardly projecting tabs formed along its length, said respective series of tabs configured to allow said cover tabs to be pushed between said barrel tabs in a lengthwise relative position of said cover over said opening, said cover tabs thereby positioned past said barrel tabs and against said barrel, said cover able to be shifted lengthwise to cause capturing of said cover tabs beneath said barrel tabs to secure said cover on said barrel, the improvement comprising:at least one locking handle assembly secured to said cover enabling positioning of said cover on said barrel overlying said opening therein and lifting of said cover from said barrel opening, said locking assembly including a graspable handle mounted on said cover by a spring blade affixed at one end to said cover and free at the other end which mounts said handle to be deflectable away from said cover to a limited extent, a locking feature fixed to said barrel side positioned opposite said handle when said cover series of tabs are aligned with spaces between said barrel spaces in said lengthwise relative position, said deflectability of said spring blade causing said locking feature to push allowing said cover to be slid to move said cover tabs past said barrel tabs with said handle on said locking feature, said locking feature configured so that said handle moves past said locking feature upon shifting of said cover so as to bring said cover tabs beneath said barrel tabs, whereat a side of said locking feature blocks a portion of said handle assembly to positively prevent shifting endwise movement of said cover in the opposite direction, whereby said cover is locked in position over said barrel side opening.
