No. 11) for the respective positions of the appellants and the
examiner with regard to the merits of this rejection.
DISCUSSION
Both Baltare and Steiner pertain to cam bushing assemblies
of the sort claimed by the appellants.
Baltare discloses a drum brake assembly 10 comprising, in
pertinent part, a spider body 42, a brake-actuating cam element
30, a cam shaft 39, a removable cam shaft support flange 44, and
a cam shaft bushing 72. As described by Baltare,
[t]he cam shaft support flange 44 comprises a
flanged portion 56 having a pattern of apertures 58
corresponding to apertures 60 provided in the upper
portion of the spider body 42 for removably attaching
the cam shaft support flange 48 [sic, 44] to the spider
body 42 by means of bolts 62 and nuts 64. The cam
shaft support flange also includes a generally hollow
tubular portion 68 defining an axially extending bore
70 in which a bushing 72 is received. The cam shaft 39
is rotationally supported within the inner diameter
bore 74 of bushing 72 [column 3, lines 30 through 39].
Steiner discloses a brake drum bearing bushing having “a
considerably improved grease distribution” (column 2, lines 4 and
5). In Steiner’s words,
a brake bridge 2 is mounted on an axle member 1.
Disposed in the brake bridge 2, at the lower end, is a
support mounting 3 for brake shoes 5 which cooperate
with a brake drum 4 and can be spread apart by a brake
cam 7 via a brake shaft 6. The brake shaft 6 is
actuated by a brake lever 8, and is mounted not only in
a support bearing 9 which is connected with the axle
member 1, but also in a journal bearing 10 which is
mounted in the brake bridge 2.
