PARALLEL PLOTTERS
Weems & Plath
Do parallel plotting in half the space! This plotter
mounted on a roller lets you plot courses and parallel lines by simple
direct transfer without the space required of traditional parallel rules
or triangles. As additional help, the plotter has distance scales at 1:20,000,
1:40,000, and 1:80,000 to fit NOS coast and harbor charts. The two rollers
keep the plotter parallel as you move it across the chart. A semi-circular
protractor lets you plot courses against a meridian if desired. The plotter
in 13 inches long.
A smaller compact version is constructed in essentially
the same way, and is well suited for plotting in more confined spaces.
Scales are 1:20,000 and 1:40,000 on an 8 inch long plotter. (Plath #120/#060).
