What reading level is Military Lance Line Construction. for Semi-Permanent Field Telegraph And Telephone Lines book?
To quickly assess the difficulty of the text, read a short excerpt:
The line-men will carry a small coil of wire, an axe, porcelain insulators, pliers and climbers. They follow in rear of the bar-men and put on the guy wire to brace the pole at each change of direction. As there is great danger of the rubber insulators breaking, a small porce- lain insulator should.be wired to the top of the pole (Fig. 3) in place of the rubber insulator where the line changes direction at any angle greater than 30° (Fig.
7). Much time can be saved and it is to their advant- 6 ...age for the line-men to keep up with the bar-men if pos- sible. The porcelain insulator is wired to the pole so that the line wire will run in the groove of the insulator.
In crossing a road where there is a lead of permanent poles, a porcelain or glass insulator should be put on the pole a few feet higher than the tops of the lance poles. This will serve to keep the wire from falling across the road in case of accident to the line and above the lops of any exceptionally high vehicles. Whenever a tree or pole is in the line of thfe proper pull-off at a change of direction, the pull-off wire should be secured at the height of the top of the lance pole.
