of the teachings of Maroschak. Additionally, while we do not
agree with the examiner that the rectilinearly movable clamps
38,39,40,41 of Hopf are "levers," we nevertheless agree with
the examiner that it would have been obvious to substitute in
Hopf for the clamps 38,39,40,41, clamps of the pivotally
mounted lever type as shown by Hoffman in Figs. 1 and 7-10.
We cannot agree, however, with either the examiner's (1)
finding that the element 6 of Hopf comprises a "group of
conveying levers" or (2) conclusion that it would have been
obvious to provide the conveying structure 6,7 of Hopf with
clamps of the pivotally mounted lever type as taught by
Hoffman. The element 6 of Hopf is described in the
translation as a "pin" (translation, pages 6 and 7) and it is
simply not clear from the showing in Fig. 1 exactly how the
pipe 4 is engaged by element 6 (although it might be inferred
that portion of the member 6 nearest the pipe somehow engages
and grips the interior of the pipe). In any event, there is
simply nothing in the combined teachings of the relied on
references which would fairly suggest providing the conveying
structure 6,7 of Hopf with clamps of the pivotally mounted
lever type as shown by Hoffman in Figs. 1 and 7-10 as the
