At that time (1830's and 1840's) it was still open whether Electromagnetic motors should be rotating or reciprocating machines, i.e. simulate a plunger rod of a steam engine. While Davenport's motor was resembling a rotating design, Pages motor was based on the plunger type, resembling a steam egine by which Page replaced the piston generating the force transmitted to the flywheel by a beam with four electric magnets.
This working demonstration model was crafted by Daniel Davis Jr., sometime after July 1838 and was mentioned in Benjamin Silliman's American Journal of Science, vol. XXXV, 1838, page 264; the oldest Scientific Journal in the United States, founded in 1818.
It is estimated that less than five of these models have survived and are only to be found in museums or major private collections. read more>>
