Patent Number	Date	Title	Name	City	Description
29,965	Sep. 11, 1860	Stave jointer	Edmund Greenlee	Rundels, Summerhill Township, PA	Edmund Greenlee was the father of identical twins Robert Lemuel and Ralph Stebbins Greenlee, who founded Greenlee Brother & Co. in 1866. Edmund reportedly developed his barrel-making machines in response to the discovery of oil in their part of Pennsylvania.
30,811	Dec. 04, 1860	Machine for finishing the inside of barrels	Edmund Greenlee	Rundels, Crawford County, PA	Edmund Greenlee was the father of identical twins Robert Lemuel and Ralph Stebbins Greenlee, who founded Greenlee Brothers & Co. in 1866. Edmund reportedly developed his barrel-making machines in response to the discovery of oil in their part of Pennsylvania.
39,268	Jul. 21, 1863	Improvement in machinery for dressing heading for cooper ware	Edmund Greenlee	Summerhill, PA	Edmund Greenlee was the father of the Greenlee brothers, Robert and Ralph, who founded Greenlee Brothers & Co.
43,985	Aug. 30, 1864	Improvement in machines for making heads to barrels	Edmund Greenlee	Summerhill, PA	Edmund Greenlee was the father of the Greenlee brother, Robert and Ralph, who founded Greenlee Brothers & Co.
102,574	May. 03, 1870	Improvement in sash-clamp	Benjamin Moore	Hart, MI
143,236	Sep. 30, 1873	Improvement in sash and door clamps	Robert L. Greenlee	Chicago, IL
153,980	Aug. 11, 1874	Improvement in relishing-machines	Albert Philipp	Clinton, IA	An example has been seen bearing this patent date and "Greenlee Bro. & Co. / Chicago Ill.". See also Canada patent 4,802.
		Improvement in relishing-machines	Frederick L. Blakely	Clinton, IA
3,767	Aug. 22, 1874	Improvements in sash and door clamps	Robert Lemuel Greenlee	Chicago, IL	This five-year patent was extended for a further five years by 10,367; see also U.S. patent 143,236.
4,802	Jun. 05, 1875	Relishing machine	Frederick L. Blakely	Clinton, IA	"Relishing machine for window-sash blind rails". This is the Canadian equivalent of U.S. patent 153,980, which was used by Greenlee Brothers & Co. This drawing for this Canadian patent is signed by "William Abercrombie, Attorney of Albert Philipp and Frederick L. Blakeley." Abercrombie was also the patent assignee, and he exhibited "relishing and mortising machines, sash clamp" at the 1876 Centennial Exhibition in Philadelphia.
		Relishing machine	Albert Philipp	Clinton, IA
4,955	Jul. 07, 1875	Machine for rebating doors	William Abercrombie	ON, Canada	The inventor describes his occupation as "gentleman". The invention is an attachment to "Abercrombie's Relishing Machine".
199,285	Jan. 15, 1878	Improvement in mortising and boring machines	Ralph S. Greenlee	Chicago, IL	The machine in this patent is considered the first successful hollow chisel mortiser design. This machine has two major differences from the typical American-designed hollow-chisel mortiser. First, it's a horizontal machine rather than vertical. Second, the drill and chisel enter the work from opposite sides. This is mechanically simpler but is limited to through-mortises only, plus bad things could happen if either drill or chisel gets deflected.
		Improvement in mortising and boring machines	Robert L. Greenlee	Chicago, IL
10,367	Aug. 18, 1879	Sash and door clamps	Robert L. Greenlee	Chicago, IL	Five-year extension to patent 3,767, which is the Canadian equivalent to U.S. patent 143,236.
239,497	Mar. 29, 1881	Feed mechanism for circular sawing machines	Joseph H. Hermance	Toledo, OH	The April 1885 issue of Carpentry and Building has an ad for the "Greenlee self-feeding saw table" whose feed mechanism is a good match for this patent. The ad says, "Patented May 29, 1881", which is not a valid patent date. Visible on the feed-arm in the machine illustration is the correct patent date.
283,341	Aug. 14, 1883	Mortising machine	Ralph S. Greenlee	Chicago, IL	Another step in the evolution of the hollow-chisel mortiser. The first Greenlee design can be seen in patent 199,285. Like this patent, the earlier design is horizontal. The major difference is that in the older design, the bit and chisel were separate and entered the work from opposite sides, which limited it to through mortises.
326,640	Sep. 22, 1885	Machine-table	Ralph S. Greenlee	Chicago, IL	This patent was used on Greenlee's No. 2 self-feed saw table, as shown in their 1892 catalog.
