Jim,
here's what I think the basic mechanism of the vertical brakes was like:
the rod from the cylinder pushes down, forcing the two angled links outward to apply force to lower end of the shoes, which are mounted to the frame with pivots at their upper ends. This adds mechanical advantage to the linkage.
As I mentioned above, the F&CC 2-8-0s that Baldwin built also had the vertical brake configuration. They had the brakes on the rear pair of drivers. Here's an enlargement from a photo of one of them as it left to join the D&RG and become a C-18:
photo from CRA No. 13, p. 176.
I have seen a better view than this somewhere else but I can't remember where at the moment. I think you can see the links I sketched.
Does this make sense?
John
