History of the Typewriter

— 161 — As will be seen by the illustration, it is based on the model of the No. 2 Remington, the paper feed and the ribbon mechanism being practically identical, and its general outlines also resembled that machine. In its construction, an. electro-magnet is used to impel the type-bars in their movement, and the same device also operates the spacing mechanism and other moving parts. The finger of the operator is merely required to touch the key corresponding to the letter desired to be imprinted, and the electric circuit is thereupon completed, and the type strikes the paper with a force which is absolutely uniform. Increase of force in no way increases the weight of the blow, but a rheostat is attached to the instrument, by means of which greater current is released, and mani- folding can be effected. Those who have used the machine declare it to be a marvel of lightness and speed, and these points, combined with its automatic and simultaneous spacing, caused many to regard it as the perfect machine at last. It is to be hoped that Dr. Thaddeus Cahill may yet live to see his invention crowned with the success which its many good points seem to indicate it merits. Faber’s Electrograph. This machine was the produc- tion of Dr. Faber of Berlin, and was invented about 1900. It contained a keyboard, similar to other machines, with eighty keys and the usual space-bar. The platen was a mounted platform, å la planchette, travelling right to left and from top to bottom of the baseboard, and the paper was laid flat thereon against guides and held by a clip. The types were suspended above the platen, and were arranged somewhat after the fashion oi the Hansen writing ball. On a key being touched, an electric current was transmitted to the piston carrying the corresponding letter, and the impression made. The writing was wholly visible. Six elements were sufficient to secure a good imprint, and the switching on of further power added such force as was required to increase the blow to any desired degree, and an almost indefinite number of carbon copies thus obtained. Ennis’s Electrical Typewriter. This machine is the invention of Mr. G. H. Ennis of Troy, but we do not know that it has yet found its way to the market. The invention contemplates the current doing all the work involved, when once the mechanism is set in motion, by a slight depression of the key. There is a lever under 11
