Small bevil gears may also be represented by simple line shading; thus in Figure 247 the two bodies A and C would readily be understood to be a bevil gear and pinion.

Figure 249 represents three bevil gears, the upper of which is line shaded, forming an excellent example for the student to copy.

To save work in drawing bevil gear wheels, they are sometimes drawn in section or in outline only; thus in Figure 244 is shown a pair of bevil wheels shown in section, and in Figure 245 is a drawing of a part of an

Figure 243 represents a drawing of one-half of a bevil gear, and an edge view projected from the same.
