Henry Disston used this patent as basis for production of his
No. 29, No. 38, No. 39, No. 42, and No. 43 series of saws.
Examples of these saws that I have seen are marked with
patent date of May 12,1856 instead of May 13,1856 as dated in
the document below. In Disston
catalogs (1876, 1909, and 1914), pictures of these saws are also marked with the patent date of May
12,1856 and Jackson Gorham name is in an arch above the date.
The Scientific American, August 15, 1857 (see next page), describes the saw
and indicates to contact H. Williams, assignee, in Atlanta GA
for more information. It also states that Jackson Gorham
filed this patent on May 12, 1856.
Hiram Smith specifically mentions this patent as a basis for
his Patent 20,313,
which he assigned to Henry Disston. In his filing
papers, Hiram also used May 12, 1856 date in reference to
Jackson Gorham's patent.
Jackson Gorham himself signed a document shown
below dated May 13, 1856.
The Scientific American, August 15, 1857 (see below),
describes the saw and indicates to contact H. Williams,
assignee, in Atlanta GA for more information. It also
states that Jackson Gorham filed this patent on May 12, 1856.
