The early 1900's Hamilton was selling the Polhemus Type Cabinet. The Triple was a huge type
cabinet work station. The front you'd pull your cases from and carry them around to the back side and compose your hand set type there.
This setup would allow three to four people to work at setting type at this cabinet, having the composing area around back allowed others to
pull cases from the front. The name for the cabinet comes from a famous printer in New York by the name of John Polhemus, he is pictured
below. These cabinets were top of the line cabinets from Hamilton at this time, so having one of these in your shop was for sure a
statement/status piece too.
