cylinder would strike it and stop the rotation 

 of the cylinder, which stopped the breaking 

 and closing of the circuit, which in turn 

 stopped the rotation of the type-wheel and 

 not only stopped it, but also put it in a posi- ; 

 tion so that the letter on the type-wheel corre- ' 

 spending to the letter on the key that was de- 

 pressed was opposite the printing mechanism. 

 The printing was done on a strip of paper, 

 which was carried forward one space each time 

 it printed. The printing mechanism was so ar- 

 ranged that so long as the wheel continued to 

 rotate it was held from printing", but the mo- 

 ment the type- wheel stopped it printed auto- 

 matically. 



The messages were delivered on strips of 

 paper as they came from the machine. 



In 1855 David E. Hughes of Kentucky pat- 

 ented a type-printing telegraph that employed 

 a different principle for rotating the type- 

 wheel. The electric current was used for 

 printing the letters and unifying the type- 

 wheels with the transmitting-apparatus. The 

 transmitter, cylinder, and the type-wheel re- 

 volved synchronously, or as nearly so as pos- 

 sible, and the printing was done without stop- 

 ping the type-wheel. Whenever a letter was 

 printed the type-wheel was corrected if there 

 was any lack of unison. 



This type of machine in a greatly improved 

 form is still used on some of the Western
