Rensselaer Semi-Weekly Republican, Volume 38, Number 21, Rensselaer, Jasper County, 7 November 1905 — A New Coal Cutter. [ARTICLE]
A New Coal Cutter.
English miners are interested in a new compressed air coal cutter recently introduced by a Sheffield firm. The machine weighs only 160 pounds, and it is 6aid that it can be used in seams so steep that the miner cannot stand upright and so thin that he has to crawl on hands and knees. A piston carrying a pick and governed by a valve movement flashes to and fro with great Bpeed, the point of the pick being gradually moved across the by , means of a lever, so that a continu- 1 ous cut is made.
