Application Number: 10/827,051
I provide a series of pairs of detachable jaw-faces
for use in connection with jaws.
The front of the jaw-face is transversely grooved to
present two parallel transverse ribs 12, which are shaped
to present sharp holding or clamping edges 13, two for
each jaw.
[T]o adjust the rise from one range of pipe sizes to
another it is only necessary to remove one pair of
jaw-faces and insert another pair of the desired
sizes and, if desired, one or more pairs of jaw-faces -
can be reserved for particular work.
From the disclosure of Yates, we find that the reference discloses a series
of pairs of detachable jaw faces for accommodating different size workpieces.
However, from the disclosure of Yates of using the clamp for clamping pipes, we
agree with appellants (Brief, pp. 13 and 14) that an artisan would not have been
motivated to add sides to the clamp as the sides would prevent the clamp from
accommodating pipes of different lengths. In addition, while Buchler does
disclose removeable, interchangeable stop blocks in figures 3 and 4, these
interchangeable stop blocks are located between the workpiece and the biasing
means 1.5.1, not between the back member and the workpiece as recited in claim
33. However, from our review of Buchler, we find that the reference discloses
(Figure 1) a clamping device for a workpiece having a front member 1.4, a back
member 1.1, opposing side members 1.1 coupled to the front and back members, a
clamping member 1.3 configured to operatively couple between the front member
1.4 and the workpiece W.
Buchler further discloses in figure 1stop blocks 1.3 and a second stop block
(unlabeled) between workpiece W and back member 1.1. Both stop blocks
contains grooves 1.7. It is further disclosed (col. 3, ll. 65-67) that grooves 1.7 also
