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.

124	Feb. 10, 1837	Weighing Heavy Bodies	Thaddeus Fairbanks	St. Johnsbury, Caledonia County, VT	Abstract: We have made certain Improvements in the Machine for Weighing Heavy Bodies in addition to those formerly made by us, and for which we obtained Letters Patent bearing date the 13th day of June, 1831 (Patent #6573); and we do hereby declare that the following is a full and exact description of our said improvement, reference being had to the drawings which accompany this specification and make part of the same; and we do further declare that in these drawings and this description we have represented and described many parts which are common to other machines for the same purpose and are found in that patented by us as aforesaid, which we have done for the purpose of more clearly explaining those parts which we believe to be new and of our own invention, and which are distinctly set forth in the claim hereunto appended. Claim: The variation in the manner of connecting the two levers in the center, (whether they be composed of one or more parts each,) to wit: by means of knife-edges resting in pendulous rings or circles, as shown in drawing No. 1, letter K, and drawing No. 2, Fig. 6, and Figs. 3 and 4.

CA-58,429	Dec. 17, 1897	Tire-setting machine	Philippe DÃ¨nÃ©ry Dupont	St. Johnsbury, VT	This tire setter uses "a series of segmental pressure blocks operated by bell cranks levers connected to a central screw" where "depression of the inner ends of the series of bell crank levers forces the pressure blocks inward, which compresses the tire paced inside the circle of pressure blocks, reducing its diameter to suit the work required." The patent also covers the gearing used to work the central screw and nut.
