Does anyone have any information on the mechanics of the drop shaft handbrakes used on flat cars?
MY 1943 Car Builders Cyclopedia shows the front portion of his devise but I am curious as to how
the chain couples to this. Is ther a second geared shaft behind the main shaft that is geared and wraps
up the chain? The front photos do not sem to leave much room for wrapping the chain on th shaft.
As usual thanks in advance for any help.
