Patents Received and/or Used by the Company

 

Patent 14,863 - 05/13/1856: Improvement in the Construction of Handsaws by Jackson Gorham

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 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. 

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.
