Symington, disappointed and discouraged, gave up his work and went to London. The rest of his life was for the most part thrown away, and he became one of the waifs and strays of London. In 1825 he received a grant of one hundred pounds from the privy purse, and later on fifty pounds more, in recognition of his services for steam navigation. He died in obscurity and although he was unquestionably the pioneer in his country of the successful application of steam to navigation on inland waters his name is only a bare memory.
Nathan Read
Born in Warren, Mass., July 2, 1759. Died near Belfast, Me., January 20, 1849.
Graduated from Harvard College in 1781, Read was a tutor at Harvard for four years. In 1788 he began experimenting to discover some way of utilizing the steam engine for propelling boats and carriages. His efforts were mainly directed toward devising lighter, more compact machinery than then generally in use. His greatest invention at that time was a substitute for the large working-beam. This was a cross-head beam which ran in guides and had a connecting-rod with which motion was communicated. The new cylinder that he invented to attach to this working-frame was double-acting. In order to make the boiler more portable he invented a multi-tubular form, and this he patented, together with the cylinder, chain-wheel, and other appliances.
The boiler was cylindrical and was placed upright or horizontal, and the furnace was carried within it. A double cylinder formed a water-jacket, connected with a water and steam chamber above, and a water-chamber below. Numerous small straight tubes connected these two chambers. Read also invented another boiler in which the fire went through small spiral tubes, very much as it does in the present-day locomotives, and this was a smoke-consuming engine. For the purpose of acquiring motion he first used paddle-wheels, but afterward adopted a chain-wheel of his own invention.
