Appeal No. 99-1752
Application 08/632,955
F.2d 893, 899, 134 USPQ 355, 360 (CCPA 1962).
Appellants’ underlying disclosure (page 1) specifies that
the principal object of the invention is to improve the drive
arrangement for a motion transmission device in such a way
that the drive shaft is subject to little mechanical stress
and wear. More specifically, appellants indicate
(specification, page 2) that a special arrangement and design
of the return spring provides a drive means which keeps the
“transverse forces on the drive shaft extremely small”.
Appellants make it clear (specification, page 4) that a
parallel force relationship results in an equilibrium of
forces such that the stress on the friction bearings 5, 6 of
the drive shaft 4 is relatively small.
Claim 1 on appeal, the same, sole independent claim as
originally filed in the application, sets forth a motion
transmitting device comprising, inter alia, a pull member
linking a control lever to an accelerator pedal, and a return
coil spring having one end engaged with the control lever and
the other end engaged with a support bracket “at locations
