Davis & Horn Page-type direct current motor

Description (Brief):

Nameplate reads: "Manufactured by / Davis & Horn / Boston." This is a balance beam electromagnetic engine with reciprocating armatures. Two curved horseshoe type magnets are wound with stiff wire, the armatures are connected by brass arms above the wooden holding plate. The magnet polarity is changed by a cut-off on the shaft of the balance wheel. Electrical connections are made under the baseboard. A small engine of this type was used to drill steel plates for gas burners. This is a very early instance of a practical application for motors.
