John Ericsson | Seeing The Light |

![]() ![]() In August of 1829, learning of a steam locomotive race that was to be held In October of that year, Ericsson formed a partnership with John Braithwaite, and in six weeks designed and built the steam locomotive Novelty. Without time to test their design, the locomotive was shipped-off to Rainhill for the trials. Weighing just over 2 tons, Novelty was much smaller than the other engines entered into the competition, and was the first to incorporate a cranked wheel mechanism. a design that would remain standard on steam engines until their demise 125 years later.
After the Rainhill Trials Ericsson turned to building ships and in 1836 he developed a successful screw mechanism for boat propulsion, which he called a "propeller." Ericsson continued to work on his Caloric engine designs, and created a more successful engine, which worked on a closed cycle with external heating. He demonstrated a working model of this "Caloric engine" in London in 1833. Ericsson's five horsepower model used two double acting cylinders, 14-inch hot cylinders, and a 10-inch diameter cold cylinder. A tubular heat exchanger was used to provide a form of regeneration. While Ericsson claimed priority of invention for this form of regeneration, Robert Stirling had in fact patented a similar system in 1816. Unfortunately, the demonstration did not meet with the rousing acceptance Ericsson had envisioned, and thus he confined his interests to standard steam power designs until 1838, when he constructed a 24 horsepower Caloric engine with a wire gauze regenerator. While the new design appeared to show promise, work on the design stopped when Ericsson, disappointed with the lack of support that he was receiving in England, immigrated to the United States the following year.
As a result of the success of the Princeton, in 1851 Ericsson managed to persuade his financial backers to build the Caloric Ship "Ericsson." The Ericsson was a two hundred and sixty-foot paddle ship powered by a four cylinder Caloric engine. Each cylinder was 168 inches in diameter, and boasted a six-foot stoke. Unfortunately, the ship was not a financial success, and even more unfortunately for Ericsson, it sank in storm off New York. As an almost personal insult to Ericsson, on being raised the ship was refitted with steam engines, which were in turn removed some time later when the vessel was converted to sail power. The ship continued in service as a sailing vessel until 1898 when it was driven ashore in a storm, off the West Coast of Canada. Ericsson was not deterred by the failure of the Caloric engine powered ship and continued to work on improving his Caloric engine concept, and was awarded patents for a number of improvements during the years 1855-1858.
At the outbreak of the Civil War President Abraham Lincoln ordered the United States Navy to build a ship that could help defeat the Confederates. Several leading engineers, including Ericsson, were asked to contribute possible designs for this new ship. When the Navy rejected his design "the Monitor", Ericsson managed to obtain a special meeting with President Lincoln. Impressing Lincoln with his ideas and design, and Lincoln granted Ericsson the contract for construction of his warship. However, the Union navy had the last word in specifying that Ericsson had to complete the construction of his ship in one hundred days, or the contract would be voided.
In 1896, the
American Steel Barge Company honored Ericsson by naming their new
whaleback steamer in his honor. The Ericsson continued to work the Great
Lakes until late 1963, when she was offered-up for use as a maritime
museum in Toronto, and then moved to Hamilton. Unfortunately, the city
of Hamilton was unable to raise the funds for her upkeep, and she
dismantled at the Strathearne Terminals in Hamilton in 1968. |
