Appeal 2007-0142
Application 10/636,964
We AFFIRM
Appellant’s invention relates to a paraffin ring adapted to be fitted
onto a spindle-like pin holder of a textile spinning machine. The paraffin is
applied to a length of yarn as it is conveyed by the spinning machine during
the manufacturing process. According to Appellant, the improvement in the
paraffin ring resides in the wear indicator or a taphole that extends into the
cylindrical paraffin member from a first end and is substantially parallel to
the insertion bore. (Specification, page 2, lines, 6-10). Claims 7 and 16, as
presented in the Brief, appear below:
7. A paraffin ring for paraffining yarn, said paraffin ring comprising:
a) a paraffin cylindrical member, said cylindrical member
having a first end and a second end, said second end adapted to
engage a yarn to be paraffined;
b) an insertion bore for receiving said cylindrical member
on a holder when paraffining yarn, said insertion bore extends
concentrically through said cylindrical member and along a central
longitudinal axis thereof; and
c) at least one taphole, said at least one taphole extends into
said cylindrical member at said first end and substantially parallel to
said insertion bore but not to said second end so that when said
cylindrical body member second end is caused to engage a yarn to
paraffin the same, said second end is worn away and said at least one
taphole is caused to extend to the worn second end and provide a
visual signal.
