Major Components of the Cradle

Two centering forks hold the telephone handset in place. O-rings placed on the tines hold a
handset firmly without marking or damaging it. O-rings can be can be added to or removed from
the tines as needed so that they are only in contact with specified areas of the handset, avoiding
buttons, etc. Adjustment knobs allow the forks to be offset and inclined, and knurled lock nuts
secure the assembly to the cradle. The two centering forks can be placed in any two of the five
sockets in the cradle bar. The five sockets are shaped to prevent the centering fork being placed
in a reversed position, which would change the direction in which the centering mechanism
functioned.
Two supports help to position the handset under test before the centering forks clamp it in place.
The supports can be extended or retracted using the adjustment knobs at the bottom of their
shafts. To prevent damage to the handset under test, a friction lock is used to limit the amount
of pressure the supports can apply. At the top of each support is a foot, which can be slid laterally
on a ratchet. Spikes, upon which the handset rests, plug into the feet.
