The Ideal Belt for Planing Machines and all drives
with constant belt-fork action, is the TULLIS PATENT
PROTECTION EDGE LAMINATED BELT.

It transmits the full' power without slip and
answers immediately to the touch of the belt-
fork, changing pulleys with surprising rapidity.

The Drive illustrated is to a Planing Machine which in-
creased its output 20 % when this Belting was installed.
