Machine for notching hoops
|
Daniel Lamson |
East Weymouth, MA |
From the 1870-10-01 issue of Scientific American: "An extension was granted to Emily J. Lamson, executrix of Daniel Lamson, for improvements in machines for notching hoops. The evidence shows that this invention was a valuable one, and that the inventor, who was a poor man, was diligent in attempting to introduce his invention until the breaking out of the war, when he enlisted in a Massachusetts regiment and was killed at Fredericksburg. Since his death his widow has continued the manufacture, but with small profits. The Commissioner says: 'This case is one in which it is eminently proper that an extension should be granted.'" |
