Patent Number	Date	Title	Name	City	Description
7,027	Jan. 15, 1850	Circular-saw mill	Nicholas G. Norcross	Lowell, MA	The patent rights for the state of Ohio were assigned to Lee and Leavitt on March 28, 1856 (information taken from "Lee v. Blandy, Southern District of Ohio, May 1860). "The nature of my invention consists in suspending the saw so that it can have lateral vibration, and when thrown out of line will recover itself by the action of the driving belt, and the arrangement of the parts by which it is sustained, while at the same time the arbor has no lateral play in its boxes, and is made to fit close with shoulders, to prevent the oil from getting out while in operationâ€”a matter of great importance when the motion is so rapid as in circular saws. This is effected by supporting the boxes in which the journals of the arbor run upon standards, to which said boxes are jointed, and which are themselves jointed to the foundation to which they are attached, so that the arbor is kept horizontal, while it is allowed a sufficient lateral play, the motion being a curved line, and of course, inclining downward as the tops of the standards recede either way from a vertical position. To sustain the frame upright, the driving belt passes around the pulley on the arbor, up over a driving pulley above, and thus holds the frame up to the proper point, so that the saw is actually suspended by the belt, while it is kept steady and made to move properly by the frame below. By this arrangement it will be seen, that while the slightest force will cause the arbor to deviate a little laterally, the constant tendency of the reacting agent is to bring it back to place again. By this means I am enabled to use a much thinner saw, and save material and power to a great degree." "What I claim as my invention and desire to secure by letters patent, is the application to circular saw frames, of rocker boxes and a swing frame, as herein set forth, and suspending said frame in position by means of the driving belt, as above described, for the free and successful operation of the saw by the motion before mentioned."
