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.

148,560 Mar. 17, 1874 Governors for Steam-Engines John C. Hoadley Lawrence, Essex County, MA Claim:
In several respects the governor is like that shown and described in the specification and drawings of Letters Patent No. 144,098, dated October 28, 1873, with which the valve-eccentric has of necessity to be arranged in close proximity with the flywheel and governor.

One object of my present invention is to enable me to dispose of the eccentric at a greater distance from the fly or band wheel, or as circumstances may require, thereby saving the necessity of placing the two in close proximity.
