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.
Richard Robotham was listed in the New York, U.S., Tax Assessment Rolls of Real and Personal Estates, 1799-1804, living in Hudson, Columbia County, NY.
Richard Robotham, a native of Nottinghamshire, England, was an inventor in Hudson, New York. Although located well up the Hudson River, the town of that name was a home port for whalers and seal hunters in the latter part of the eighteenth century and a processing center for oil from sperm whales and elephant seals. Robotham received two patents, for processes of candle manufacturing in 1794 and purification of spermaceti oil in 1799, that were related to that industry. He also took out patents on a composition material for flooring and a machine for ruling paper. By 1805 he developed a design for arched bridges made of pine boards and built at least two of the bridges on turnpikes. He later was an inspector of the Hudson Aqueduct Company and served on a committee to administer a public bathhouse. Robotham also invested in real estate. Several times beginning in 1810 he sought election as an overseer of roads on the Federalist ticket.
