Re: Modeling a Lever Hand Brake

Group,

i think the closest to this prototype is actually the Accurail USRA 55 ton hopper brake lever part. Most of the other parts suggested use a chain at the mechanism and a bell crank at the sill while offering mechanical advantage. The lever in the photo is used to turn the brake staff and the chain tightens on the bottom of the shaft.  It looks like the lever handle folds up to horizontal to turn the shaft and the ratchet above the end sill allows the handle to to swing back when it fouls with the end boards. Thank you for the insights.
