Description: |
| The inventor was partner in the large Cincinnati carpentry firm of Hinkle & Guild, innovators in pre-fabricated building. "Guild's Patent Mortising Machines, for Hubs and Square work" was listed in an ad for James L. Haven & Co. in an 1854 directory. The October 1890 issue of Industry says that Guild invented the "graduated stroke mortising machine", and the machine was subsequently manufactured by Lane & Bodley. The article also says that the graduated stroke mortiser design was widely produced by Cincinnati makers but no-where else as others failed to realize its advantages. Other (non-Cincinnati) makers used the "variable-stroke" design where the stroke must be equal both below and above the surface of the stock, whereas the graduated-stroke machine needs much less stroke above the surface.The 1853-12-31 Scientific American, page 126, has an article on this invention, which was "Manufactured by Lane & Bodley, to whom all orders should be addressed. This firm, and that of Geo. H. Knight & Brother, of the same city, are joint owners of the patent."According to the 1873 "Subject-matter index of patents for inventions issued by the United States Patent Office", this patent was granted an extension. |
