Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
"Be it known that I, the said Cyrus Durand, have invented a new and useful improvement in the art of copper-plate printing, by an improved press, intended particularly, for copper-plate printing; which invention, and the manner of using it, are as follows. This improvement consists, in the first place, of a bench, or table, perfectly level on the top, made either of wood or metal, upon which is placed a number of rollers, viz. 2, 4, 6, or more. These rollers being fixed in their proper situations by means of an iron frame surrounding them, on these rollers is placed the plank, or bed, of the common press, on which the plate is laid for printing; over which the large roller is to pass. This improvement, therefore, consists in the movement of the plank upon the small rollers; these moving at the same time with the frame surrounding them on the surface of the bench, or table, by means of which the friction attending ordinary presses is almost entirely removed; the labour not so great, and the impression more perfect. The cross, or levers, for turning the press, screws, &c. are similar to those that are used in the common presses."
