PHANTOM 2. - BRAKE OPERATING GEAR.

This is to confirm having handed to you yesterday
N. scheme 2988. - Damper for the Swinging Arm of the Brake
Gear, Phantom 2. - for the purpose of experiment.

It will be seen that a new gearbox casing with
a boss on the brake compensator arm is needed.

It will also be seen that the dashpot constitutes
the stop for the front brakes; the stop for the back brakes
is as now, that is to say, we believe the sheet metal lever
jams in the fork.

We have assumed that you do not require any
additional backward stops other than you have already,
and are satisfied, for example, with the 20 HP., in which
there appears to be no stop.
