Patent Number	Date	Title	Name	City	Description
11,511	Aug. 08, 1854	Fan-blower	Solomon W. Ruggles	Fitchburg, MA
16,814	Mar. 10, 1857	Circular sawing machine	Charles P. S. Wardwell	Lake Village, NH	This double-arbor tablesaw was a big commercial success, and the basic design remained popular for over 100 years until better combination blades made it less advantageous to have two different blades readily available. The Wardwell saw was sold by Wardwell himself from 1857-1863 (based on ads in Scientific American), then by James Goodrich & Co. (1867 ad), L. D. Fay of Worcester (1868-1869 ads in Scientific American), then by Rollstone Machine Works (1872-1883 ads in Manufacturer & Builder). Wardwell applied for an extension to this patent. It appears that his request was denied.
26,192	Nov. 22, 1859	Lathe attachment	Cheney Kilburn	Burlington, VT	The June 1873 issue of Manufacturer & Builder has an article on a "lathe with the Kilburn smoothing-knife attachment", made by Rollstone Machine Works. An 1878 ad for Rollstone Machine Works lists "Gauge Lathes with Kilburn Patent Finishing Knife Attachment, for Chair, Furniture, Handle, Balusters and other nice Turning".
58,498	Oct. 02, 1866	Angular saw-gage	Elbridge G. Stanley	Fitchburg, MA	Inventor Goodrich was the founder of James Goodrich & Co., which became Rollstone Machine Works about 1867. These companies made Wardwell's patent tablesaw (patent 16,814), among other products. An article in the 1880-06-05 American Machinist features a saw table bearing this patent date along with the date for patent 16,814.

89,652	May. 04, 1869	Improvement in self-oiling pulleys	Henry J. Colburn	Fitchburg, MA
		Improvement in self-oiling pulleys	James Goodrich	Fitchburg, MA
110,451	Dec. 27, 1870	Improvement in saw-mills	Charles M. Flint	Hancock, NH	An 1871 ad for Rollstone Machine Works lists "Flints Patent Saw Mills" among their products. An 1898 ad for F. S. Lovell Machine Works featured "Flint's patent lever set circular sawmills". Other information indicates that Franklin S. Lovell bought out Charles M. Flint's works in Fitchburg, MA, in 1888.
111,632	Feb. 07, 1871	Improvement in planing-machines	Henry J. Colburn	Fitchburg, MA	The reissue of this patent was assigned to William H. Doane, who was the president of J. A. Fay & Co. This patent was the subject of litigation; see the link to Fay v. Preble.
		Improvement in planing-machines	James Goodrich	Fitchburg, MA
112,759	Mar. 14, 1871	Lathe dog	Henry K. White	Chelsea, MA	"In turning small round stuff, like chair legs, in wood turning lathes, it is customary to fasten one end of the stick by forcing it against a mandrel-dog, having radial teeth, that sink into the wood and hold it fast, or cause it to be held fast between the dog and the back poppet, so that the stick turns with and by the rotating mandrel. These teeth are very liable to split the wood, especially when the wood is turned down nearly to them and the object of my invention is to so construct the clamping-dog as to insure the wood against any liability to split by the action of the teeth; and for this purpose I make or provide the dog-stock with an encompassing-sleeve or tube, which is internally screw threaded or nut-threaded, and works upon a male thread on the stock, the front end of the tube being made sharp, so that, when fed up into the plane of the ends of the dog-teeth, or slightly projecting beyond them, the said edge shall strike into the end of the stick to be turned, thereby holding the material, into which the teeth enter, and effectually preventing it from splitting, although the turning-tool may cut down to the tube." An article in the 1871-07-19 American Artisan describes the invention and notes that it was being manufactured by the Rollstone Machine Works.

250,425	Dec. 06, 1881	Circular sawing machine	Henry J. Colburn	Fitchburg, MA	This saw was seen in an 1898 ad for Baker Brothers of Toledo.
250,712	Dec. 13, 1881	Circular sawing machine	Henry J. Colburn	Fitchburg, MA	This is a double-arbor saw of the Wardwell type, i.e., with two arbors mounted on a rotating frame so that one blade can be raised above the table while the other is simultaneously lowered below the table.
