mixes the material as the material is being conveyed. In that
regard, Reed teaches (column 4, lines 19-22) that
[c]onveyor 80 then passes mixed components into pug mill
122 which thoroughly distributes the components before
passing the same into chute 132 and spreader box 136 for
use on surface 142.
Reed also teaches (column 3, lines 55-58) that as shown in
Figures 3, 7, and 8
[p]ug mill 122 comprises a pair of counter rotating
augers 124 and 126 which are driven by hydraulic motor
128 through gear drive 130.
Additionally, as shown in Figure 1, the conveyor 80 drops the
mixed components into the left side of the pug mill 122 which
passes the components into chute 132 at the right side of pug
mill 122. Accordingly, it is our determination that Reed's
pug mill 122 clearly conveys the mixed components from the
left side of the pug mill where the components are deposited
from conveyor 80 to the right side of the pug mill 122 for
deposit in chute 132. Thus, Reed's pug mill 122 clearly is a
single structural component which conveys the components as
well as mixes the components as the components are being
conveyed.
