notes: label: Description
content: This model is a metal stamping power press patented as U.S. patent No. 110,455 on December 27, 1980, by Albert D. Hamlin of Brooklyn, New York. The model has a green body and a red wheel. Hamlin provided innovations to this machine that would stop the plunger at the top of its stroke, when out of the way of the bed or lower die, and for holding said plunger in its raised position without stopping the pulley or running wheel that drives the operating shaft of the press. The pitman operated the plunger within V-shaped slides on the ladder. With this, the pitman would be able to work with the mandrel box, or guide, that carried the V-sides through without the need to adjust them. Overall, this would create a steader pressing action.
