Circular sawing machine

Charles P. S. Wardwell |
Lake Village, NH |
This double-arbor tablesaw was a big commercial success, and the basic design remained popular for over 100 years until better combination blades made it less advantageous to have two different blades readily available. The Wardwell saw was sold by Wardwell himself from 1857-1863 (based on ads in Scientific American), then by James Goodrich & Co. (1867 ad), L. D. Fay of Worcester (1868-1869 ads in Scientific American), then by Rollstone Machine Works (1872-1883 ads in Manufacturer & Builder).
Wardwell applied for an extension to this patent. It appears that his request was denied. |
