Abstract
A railroad car hand brake has a housing with a chain opening in said housing. There is a shaft mounted in the housing which mounts a chain drum which is rotated by a drive gear. The drum is formed and adapted to engage a link chain whereby turning of the drum moves the chain inwardly through the housing opening, around the drum and then outwardly through the housing opening. A chain stripper is attached to the housing and has a portion thereof positioned between the incoming and outgoing chain, in alignment with and extending toward the drum to prevent the chain from wrapping around the drum.
