"The machine itself is sufficiently simple, and will be comprehended at once, by those who have made electro-magnetic experiments, by the annexed diagram and description. The temporary magnet a, enveloped with its insulated copper wire, is fastened to the wooden frame b, g, by means of cords or otherwise. The frame also supports the standard h, which sustains the revolving drum f, on which the paper to receive the emblematical alphabet is fixed, m being the edge of the paper. To the arm g, is appended the lever c, of wood, which has a slight vertical motion, in one direction by the steel spring d, and in the other, by the armature of soft iron e." —Comstock, 1850
