"Vintage Machinery" entry for Marinette Iron Works Co.
An 1875 ad from Willard Lamb shows this invention. "Foundrymen and saw mill machinists are requested to apply to me for manufacturers' licenses and terms of royalty. There is a list of 15 references, which we assume were users of the invention. Follow the link provided to Wm. H. Hiner & Co. and then look at the "Images" tab on that page to view the ad. One of the companies listed in the ad is E. P. Allis & Co., and an ad from that firm in the same book as the Lamb ad includes this text: "We make Willard Lamb's patent wire rope carriage movement that dispenses entirely with the cog gear. The Saw Carriage is much lighter and can be handled much more rapidly and at a much less expense than the old movements."
