Locking the Verticle Movement:
The TOM Drafting Machine does not have a counterweight. The
vertical sliding block in balanced by positioning the brake lever (D).
This is moved by pressing downwards and then to either side to
desired position (see Figure 4).
Locked position (no drawing head movement)
Braking friction position (prevents drawing head from
slipping downwards)
Unlocked position (free movement of drawing head)
Locking the Horizontal Track Movement:
The horizontal sliding block is locked in position by means of
lever (E) (see Figure 5).
WARNING: Never leave the brakes in the locked position when
the drafting machine is not in use, as this may cause warping
of the bearings.
Correcting Position:
The vertical bar of the drafting machine must always be parallel to the
surface of the drawing board. If it is not, loosen screw (F) and adjust
the knob movement in its slot. Once it is lined up correctly, tighten the
screw again.
If necessary, the knob fitting (G) can run along the vertical bar of the
drafting machine (see Figure 6).
