Description: |
| NX series patents are pre-July 1836 patents that do not have numbers and are not listed in the X patent series. They have been arbitrarily assigned NX numbers, which consists of the issue date in ISO format followed by a single number to separate multiple patents issued on the same date. This is to allow them to be entered into the Datamp file. They are entered here for reference and further research only.This patent was probably never issued as it has never been listed in any of the Patent Office compendiums of pre-1836 patents. We know of its existence from The American Journal of Improvements in the Useful Arts, and Mirror of the Patent Office in the United States, Vol. 1 No. 2 (April-June 1828), as well as The Franklin Journal and American Mechanics' Magazine for October 1828. Our inventor, Uriah Brown, was one of the originators of the short-lived American Journal of Improvements mentioned above."...a new and useful improvement in the steam engine, denominated 'The Double Tangent Chain Lever;' the object of which, is to transmit motion and power from the piston to the lever or working beam, and to convert the rectilinear motion of the piston, into a reciprocating circular, or a continuous circular motion... This object, I propose to accomplish by means of two chains (a and b,) alternately working over the periphery of an arc at the extremity of the impelled end of the lever..." |
