Patent Number	Date	Title	Name	City	Description
150,625	May. 05, 1874	Tempering and Forming Articles of Steel	George F. Simonds	Fitchburg, MA	The patent is a set of clamps and related tempering processes for forming circular saw blades. The clamp also appears in pat. no. 151,167 for the furnace in which this process would be carried out.
		Tempering and Forming Articles of Steel	James A. Ferson	Fitchburg, MA
151,167	May. 19, 1874	Improvement in Tempering Ovens for Steel and Iron	George F. Simonds	Fitchburg, MA	Claims even distribution of heat utilizing an intervening preforated plate between the fire and clamps as well as patenting the general construction method of utilizing passages, a hot air chamber, and tiles to further distribute the heat. George Simonds references this patent in his application for Patent No. 169,736. Additionally, this appears to be an improvement over Patent No. 150,625 which uses clamps to prevent warping of the circular saw blade.
169,736	Nov. 09, 1875	Improvement in Tempering and Forming Articles of Steel	George F. Simonds	Fitchburg, MA	Listed as an improvement on Patent No. 151167.
RE7,465	Jan. 16, 1877	Improvement in Tempering and Forming Article of Steel	George F. Simonds	Fitchburg, MA	Improvement on original process of tempering and straightening saws through use of heat and pressure without hammering to acheive flatness. Saw is left in the final form upon completion of tempering. Text cites this as an improvement on his Patent No. 151,167.
RE7,464	Jan. 16, 1877	Improvement in Tempering and Forming Article of Steel	George F. Simonds	Fitchburg, MA

269,728	Dec. 26, 1882	Crosscut-saw	George F. Simonds	Fitchburg, MA	An 1890 catalog from Pritzloff Hardware Co. shows a Simonds saw blade with "The 'Simonds' Saw / Crescent Ground / Patented Dec. 26, 1882" on it.
326,684	Sep. 22, 1885	Saw with insertable teeth	George F. Simonds	Fitchburg, MA	The wrench to install and remove this saw tooth is covered by patent 326,683.
326,685	Sep. 22, 1885	Insertable-tooth saw	George F. Simonds	Fitchburg, MA
346,565	Aug. 03, 1886	Band-saw	Daniel Simonds	Fitchburg, MA	"My invention relates to narrow sawsâ€”such as band-sawsâ€”and has for its object to produce a saw which can cut a curve within a minimum limit and leave a good finish on the material being cut... to this end my invention consists in a band or similar narrow saw having a beveled blade and milled teeth that are not set."
375,350	Dec. 27, 1887	Saw Screw	Charles Glover	Hartford, CT	The primary focus of this patent is on the two-part construction of the saw medallion ("label screw"). In a sense, it can be seen as an improvement on Munger's patent (U.S.P.N 98180), which had no provision for preventing the shaft from twisting independent of the head if the swaged fit failed. The large show surface of Glover's medallion, in conjunction with the shoulder beneath it, allowed for the addition of longitudinal ribs on the shaft of the screw to resist turning. The medallion (figures 2, 3 & 4) and the saw screw (figure 5) shown in Glover's patent drawings both feature the internally threaded construction patented by Henry Disston in 1876 (U.S.P.N. 181648). This form displaces the through screw and "split nut" arrangement which had been the norm. Glover's saw screw differs from Disston's by being formed in a die rather than being cast and having longitudinal ribs on the shaft rather than a square section to resist turning. Also, though not specified in the patent, the shafts of Glover's saw nuts were of stouter construction. Glover's form eventually superseded Disston's. Saw medallions with this patent date have been found on saws from a wide variety of saw manufacturers.

632,133	Aug. 29, 1899	Saw-tool	Harry G. Manning	Fitchburg, MA	Examples are labeled "Simonds Crescent Saw Tool" and the patent date.
638,268	Dec. 05, 1899	Saw-Handle	Ezra B. Olson	Oleona, PA
774,780	Nov. 15, 1904	Frame Saw	Alfred M. Remington	Fitchburg, MA
D39,122	Feb. 11, 1908	Hacksaw Frame	Lloyd Alonzo Kimball	New York, NY	The distinctive feature is the shape of the grip. The frame and patent date appear in a 1910 Simonds Mfg. Co. hacksaw advertisement. Term of patent 14 years.
885,521	Apr. 21, 1908	Handsaw	Alfred M. Remington	Fitchburg, MA	Actual production model does not closely follow the patent drawings. Blade may be adjusted and positioned at any angle up to 90 degrees or reversed. Connecting slots in the blade which form a "T" and the position is controlled with two pins which ride in slot. Put into production by Simonds, but the "T" slot was not an element of the patent. The key visual identification means for this patent is the conventional wing nut used to tighten the blade in the desired position vice the single lever used by Disston and others, 938680.
