The former contents of this Notebook are now offline because I found aspects of them to be inaccurate. I am now in the process of completely reworking this Notebook from scratch. It is intended to cover all of Benton's pantographs (both vertical and horizontal), with particular attention to their origins (they were not the first) and technical details.
I have been fortunate enough to have acquired one of the few surviving Benton pantographs. I'll document my work on it here.
A Census
A Census of Benton and Related Pantographic Engraving Machines. This includes not only the Benton vertical pantographs, but also the Benton horizontal pantographs and close copies of the Benton vertical pantographs by Tsugami and others.
This is an open source document, which means (obviously) that its sources must be open. The icon at left links to another page in a subdirectory which has the document (in PDF format) and its complete source material.
Machine Dossier for BEM2a-53
This is a central location for the distribution of all information that I have learned about the Benton Engraving Machine, Type 2a, No. 53 (a single-arm vertical pantographic typographical engraving machine) at CircuitousRoot. ATF Machine Number 53, CircuitousRoot Identification Code: BEM2a-53.
This is incomplete, not just in the theoretical sense that a document such as this can never be complete but also in the pragmatic sense - there is a lot left to do. It has some interesting information, though.
