"Vintage Machinery" entry for Henry Disston & Sons
Combination square and saw and the first in the 7/150 catagory. This patent was utilized by Henry Disston in the No. 42 and 43 series of saws and early examples will bear the incorrect patent mark of MAY 12,1856 instead of MAY 13,1856. Hiram Smith specifically mentions this patent as a basis for his patent, 20313, which was assigned to Henry Disston.

Disston catalog pictures as well as know examples are marked with the incorrect patent date of MAY 12,1856 as well as JACKSON GORMAN in an arch above the date.

A featured article in Scientific American, 15 AUG 1857, describes the saw as well as indicates to contact H. Williams, assignee, in Atlanta GA for more information.
