An 1890 Rowley & Hermance catalog shows a "Eureka pin making and pointing machine" that bears an (invalid) patent date of "May 19th, 1876". The machine is clearly labeled, "Rowley & Hermance, Manufacturers". The only patent we can find that fits is this one, even though the layout of the machine is substantially different. It appears that Rowley & Hermance modified the design by "folding" the mechanism to make it more compact. |
