respective positions articulated by the appellants and the examiner. As a consequence
of our review, we make the determinations which follow.
Independent claims 19 and 26 read as follows:
19. A seal device for use in an adjustable tappet assembly
for a disc brake for sealing between an internally threaded
outer sleeve and an externally threaded internal shaft of the
assembly, said device comprising a support element
adapted to be carried by said sleeve, said support element
carrying a seal for sealing between said sleeve and said
shaft having a lip portion arranged to engage an unthreaded
surface portion of said shaft in sealing relationship for
providing sealing during axial movement of said shaft relative
to said sleeve.
26. An adjustable tappet assembly for a disc brake
comprising an internally threaded outer sleeve, an externally
threaded internal shaft, and a seal device, said seal device
having a support element carried by said sleeve, said
support element carrying a seal for sealing between said
sleeve and said shaft having a lip portion arranged to
engage an unthreaded surface portion of said shaft in
sealing relationship for providing sealing during axial
movement of said shaft relative to said sleeve.
Baumgartner, the primary reference relied upon by the examiner, comprises an
adjustable disc brake thrust assembly comprising an externally threaded spindle 70 and
an internally threaded traverse member 7. The spindle 70 is rotated by an adjusting
device (not shown) as discussed in column 5, line 48 et seq. and column 6, line 42 et
seq. when excessive ventilating play exists during brake application, for example, after a
change of the lining or with an increasing wear of the brake shoes, to thereby reduce
the distance to the brake disc to compensate, for example, for the wear of the brake
