Abstract
A friction brake and safety slip clutch is positioned between a gumbox and a hand operated pinion shaft used to raise and lower the gumbox into contact with sealant transfer rollers of an apparatus for applying sealant material to envelopes. The brake and clutch prevents the gumbox from falling from a raised elevation during rotation of the pinion shaft or after the elevation has been attained.
