Description:
Inventor Obersin Smith became much better known as the inventor of magnetic recording, which occurred in 1888. After graduating from engineering college in the early 1860s, he went to work for the Cumberland Nail & Iron Works, for whom he developed and patented a machine to cut and ream iron pipe. In 1863 he established a machine shop, taking in a partner, cousin J. Burkett Webb, the following year. Smith & Webb made sheet metal presses. Smith then went on a sort of inventing binge, of which this countersink is a small part.
