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." |
