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.
“The principal object of this invention is to use propellers of timber, to cause wagons or cars to ascend on an inclined plane, instead of drawing them up by ropes, or chains.
The propellers are long pieces of timber, placed between the ways of a rail-road. They are to be three in number, lying side by side, and may be on the same plane with the rails; they are proposed to be made of timber, about 6 by 8 inches, and may be so joined end to end as to extend to any convenient distance; they are to be supported on rollers, upon which they are retained by flanches. A shaft crosses the rail-road, below the rails and the propellers; upon this shaft there are three cranks, from each of which a pitman passes to one of the propellers, and when this shaft is turned, by the application of any sufficient power, one of the propellers will always be advancing. The upper edges of these propellers are notched, so as to form ratchets; and three palls descend from the bottom of the wagon, and fall into these ratchets, which will, of course, cause it to ascend by a regular, continuous, motion.”
