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.'
