In July, 1904 the Hardware Dealers' Magazine
published an announcement about availability of Langdon Acme
Miter Box by Millers Falls Co.:
'The Millers Falls Co., 28 Warren Street, New York, is offering
the trade the “Langdon” Acme Miter Box, illustrated. The makers
state that this Box embodies all important features in boxes
heretofore made, and has a number of improvements.
The guides are made one inch longer, thus holding the saw more
steadily when drawn up to its highest capacity. These guides are
provided with elevator so that the saw is held stationary above
the work when desired, as shown in the illustration.
In addition to the notches for the positive angles commonly in
use, there is provided a graduated arc in front with the various
degrees marked thereon, as shown by the plate in illustration.'
