Patent Number	Date	Title	Name	City	Description
10,204	Nov. 08, 1853	Machine for turning or cutting irregular forms	Nathaniel Gear	Zanesville, OH	Extended 1867-09-30 for 7 years. See also patent 86,605 and patent 99,446. This patent is generally recognized as the genesis of the spindle shaper, although a handful of earlier patents embody essentially the same idea but for specialized uses (click on the "Tool Categories: shapers" to see a list of early spindle shaper patents). Spindle shapers have a couple of advantages over molding machines. Most importantly, they can easily create curved moldings. Outside curves can be of any desired radius; inside curves, of course, cannot be of smaller radius than the cutterhead.

96,407	Nov. 02, 1869	Improvement in step for vertical spindle	Benjamin F. Dunklee	Concord, NH	Invention is a self-lubricating vertical spindle. Seen also on a spindle shaper from John A. White Co., but the patent was likely expired by then.
