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.
“For Avoiding the Dead Point in the Crank in the Steam Engine; Valentine Carter, Washington county, District of Columbia, August 3.
This is a new and unimproved edition, of what has been many times patented, essayed, and abandoned. A double rack, formed by teeth within the two sides of an oblong frame, and a pinion with which the racks are alternately to engage and disengage, constitute the invention. The claim is to the combination of the whole. A cent for each impression made from engravings of similar contrivances, would be a sufficient fortune for any one whom a lack of roupees would content; and if to this was added the amount which has been expended and lost in attempts to carry the plan into execution, a very comfortable addition would be made to the capital.”
