The evolution of the driving mechanism for the Barth Type Caster, illustrated by a Size No. 3 1/2 machine equipped with a 60 point mold.

This is amateur hand-held-camera video of poor quality (but I trust of interesting content if you care about these machines).

Minor correction:  In the video I say that the style B4 mold was associated with the Bruce's New York Type Foundry.  That isn't quite right.  Surviving ATF data indicates that it was associated with ATF's manufacturing foundry B, which was their New York branch.  This branch consisted initially of the Conner foundry (the United States Type Foundry of James Connor's Sons), merged with whatever assets were kept from the Manhattan Type Foundry of P. H. Heinrich and the A. W. Lindsay foundry.  ATF later did acquire Bruce's NY Type Foundry, but it isn't clear if they merged this into Foundry B or (more likely) directly into the then newly established Central Plant in New Jersey.

For more information on the restoration of this Barth type caster (still barely started as I post this video), see:
