Summary
[edit]
| Description |
English: Thomas Wright, London, devised the first apparatus (1845) in which the adjustment of the carbons is brought about automatically. W. C. Staite used the electric current for the regulation of the carbons in 1848. The apparatus represented in Fig. 425 is the regulator of Archereau, constructed in 1849 on the same principle as that by Staite and Perie. A B, C D, and AC consist of copper; t is the fixed positive carbon. The solenoid s is fastened between the rods E F and G H. To the rod J K is fastened the negative carbon t'. The current enters the solenoid through the positive wire, and leaves the apparatus at D. |
