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 principle upon which this engine is to act, is the same which has been tried in a great variety of forms, and always with the same result, namely, that it would go, if well made, but was inferior in operation to the cylinder engine. We cannot give the particular arrangement proposed, without drawings, and deem it sufficient to observe, that a wheel is to revolve, upon the periphery of which there are valves, which shut flush into it, and are to open and be acted upon as they pass through steam boxes, of which there are two, one standing opposite to the other, and each furnished with a steam and escape pipe.”
Journal of the Franklin Institute Vol. 6, Sept. 1829 pg. 178
