Morse Telegraph Register

| View Cart ⇗ | Info

“The Morse register is represented [here]. The armature, A , is supported at the end of a lever, and over the cores of the magnet bobbins, M. A spring, S, lifts the armature when the cores are demagnetized on the breaking of the circuit by the operator at the key. When A is pulled down by M, a style or pencil at P is pressed against R, a paper ribbon that is drawn along by clock work. this style may be made to record upon the paper a dot-and-dash communication sent by the operator at a key, perhaps hundreds of miles away.” -Avery 1895
