History of the Typewriter

—311— The transmitting typewriter in size and general appear- ance is not unlike that of other typewriters of its class. As a matter of fact it is two machines in one ; a complete typewriter and a telegraph transmitter. When the machine is not in use it may really be said to consist of three parts, the typewriter, the transmitter and the keyboard. If the typewriter part of the machine is to be used, the depression of a lever at .the right of the frame connects it with the keyboard, and when the work is complete the raising of this lever again disconnects it. If the transmitter is to be used the depression of a lever at the left of the frame connects it with the keyboard and opens the telegraph circuit ; the raising of this lever at the completion of the work of trans- mitting again disconnects the transmitter and closes the telegraph circuit. The typewriter and the transmitter may be connected with the keyboard at the same time by the depression of both the levers above referred to, so that a mechanically correct copy of the matter transmitted may be secured. The machine may be permanently connected into a telegraph circuit by simply cutting the wire and inserting the two cut ends into binding posts fixed in the frame at the rear. Temporary connection, into any circuit may be made by the use of a cord and jack placed under the spring of the Morse key circuit closer, so that the machine can, be moved quickly from one wire to another like any ordinary typewriter. The typewriter part of the machine has been subjected to the severest possible tests, covering a period of many months of practical work. In all of these it has proved itself to be superior to anything of the kind yet put upon the market. Every letter, every word and every line written is in plain sight from the time the first letter is struck until the paper has been removed from the machine. That this feature of “ visible ” writing is invaluable in a typewriter to be used for telegraph purposes, is admitted by all. Ilie carriage is returned by one direct downward move- ment of a lever at the right of the keyboard ; the line spacing is accomplished automatically at the same time by the same motion. Ihe paper feed has been constructed with special reference to the rapid handling of telegraph blanks. Ihe carriage moves upon ball bearings and the typebars, which are the real like of a typewriter, are con- nected into their hangers by ball bearings. The touch is
