Key to Links for Patent Information

USPTO = U.S. Patent Office . Images of the actual patent can be viewed on the U.S. Patent Office web site but a special TIFF viewer must be installed with your browser in order properly work. More information on how to configure your computer to view these patents can be found at TIFF image Viewers for Patent Images.
DATAMP = Directory of American Tool And Machinery Patents . A sister site to VintageMachinery.org with information on patents related to machinery and tools. A much easier user interface than the USPTO's for finding information on machinery patents.

106,260	Aug. 09, 1870	Improvement in machine for manufacturing hoops	John B. Dougherty	Rochester, NY
203,429	May. 07, 1878	Improvement in machines for cutting hoops from the log	John B. Dougherty	Rochester, NY	Assignee Burrell, Ives & Co. was a company best known for making veneers; they may have had a sideline in wooden barrel-hoops, which were needed not only for manufacturing barrels, but for replacing worn-out hoops on older barrels. Wooden hoops had to be replaced every few years, which is why they were eventually obsoleted by iron hoops.
207,721	Sep. 03, 1878	Improvement in hoops	John B. Dougherty	Rochester, NY	Wooden hoop is pressed into shape using dies.
209,962	Nov. 19, 1878	Improvement in hoop-cutting machines	John B. Dougherty	Rochester, NY
210,100	Nov. 19, 1878	Improvement in circular sawing machines	John Connell	Rochester, NY	This is the earliest appearance we have seen of the tablesaw trunnion mechanism. Previous tilting-arbor tablesaw designs used a physical pivot point well below the surface of the table; the result is that when the blade is tilted, its line of intersection with the tabletop moves laterally, which complicates setup and is a safety concern because a wider table slot is required. Connell's design replaces the physical hinge-pin with trunnions centered on a virtual axis in the same plane as the tabletop. As the blade tilts, it maintains a fixed line of intersection with the tabletop. "The object of my invention is mainly to hang the saw-arbor of a tilting sawing-machine in such a manner that the pivotal or axial line of the tilting movement shall lie in the plane of the saw, also in or near the plane of the upper surface of the table, whereby the saw, while being tilted, has no lateral movement at the said line, or, in other words, does not materially change its place in the narrow slit in the table up through which it projects; also, the employment of a pinion and rack to conveniently tilt the saw, and stop-pins to limit the angle of its inclination."
211,715	Jan. 28, 1879	Improvement in barrel-hoop machines	John B. Dougherty	Rochester, NY
211,716	Jan. 28, 1879	Improvement in machines for dressing and compressing hoops	James Naylor Jr.	Rochester, NY
		Improvement in machines for dressing and compressing hoops	John B. Dougherty	Rochester, NY
243,692	Jul. 05, 1881	Resawing machine	John Connell	Rochester, NY	The machine of this patent was seen in an 1889 ad for Connell & Dengler. This patent date is also visible on catalog pages for the "50-inch Improved, New Style Re-Sawing Machine" from Cordesman Machine Co.; also listed is the date for patent 279,344, which covers the saw blade. Since both the resaw and blade were designed by Connell & Dengler, it raises the possibility that they were built by them and Cordesman was merely a reseller. The catalog copy repeatedly refers to "our" saw but the saw in the illustration does not have either maker's name on it. It seems plausible, but uncertain, that Cordesman licensed the design from Connell & Dengler so we tentatively list Cordesman Machine Co. as a manufacturer of this invention.

256,468	Apr. 18, 1882	Hoop-making machine	John B. Dougherty	Rochester, NY	"My invention relates to that class of hoop-machines in which the hoop is cut from the edge of a plank by a reciprocating knife. "In the manufacture of this kind of hoops as heretofore practiced the hoop-splint has been cut from the plank in one machine, and the splints have been then passed in turn through a number of other machines, in which the splint was lapped, tapered, and pointed, the process requiring many successive handlings and producing a large percentage of 'culls.' "My invention has for its object the production of a machine in which hoops are cut from the lumber and lapped, tapered, and pointed at one operation by automatic machinery, without the necessity of rehandling, the hoops being delivered from the machine ready to be placed on the barrel, with the exception of planing the outer surface for the purpose of rounding the corners, which may be practiced, if desired; and my invention consists in combining with a reciprocating dividing-knife automatically-operating lapping or tapering and pointing knives, all as hereinafter more fully set forth."
279,344	Jun. 12, 1883	Segment-saw	John Connell	Rochester, NY	This patent date is visible on catalog pages for the "50-inch Improved, New Style Re-Sawing Machine" from Cordesman Machine Co.; also listed is the date for patent 243,692, which covers the resaw machine itself. Since both machine and blade were designed by Connell & Dengler, it raises the possibility that they were built by them and Cordesman was merely a reseller. The catalog copy repeatedly refers to "our" saw but the saw in the illustration does not have either maker's name on it. It seems plausible, but uncertain, that Cordesman licensed the design from Connell & Dengler so we tentatively list Cordesman Machine Co. as a manufacturer of this invention.
