Appeal No. 2001-0673
Application No. 09/138,445
1. A gun for spraying paint and reflective beads onto a
surface, said gun comprising:
an airless tip assembly which atomizes paint passed
therethrough at a locus of atomization shortly in
front of said tip assembly; and
means for injecting reflective beads approximately
into said locus of atomization, said injecting
means being attached to a source of reflective
beads.
As evidence of obviousness, the examiner relies on the
following references:
Bollag 4,856,931 Aug. 15, 1989
Waggoner 3,844,485 Oct. 29, 1974
Claims 1 and 2 stand rejected under 35 U.S.C. § 103 as
being unpatentable over Bollag in view of Waggoner.
The examiner’s explanation of the rejection is found on
page 3 of the answer and reads as follows:
The Bollag reference discloses a spray striping
apparatus comprising a conventional sprayer nozzle
arrangement with a “tip” 2 for paint and an “injection
means” 4 for beads, but does not disclose the paint
tip as being an “airless tip”. The Waggoner reference
discloses another sprayer having an airless tip 22.
It would have been obvious to one of ordinary skill in
the art to substitute a sprayer with an associated
“airless tip” (if not already) as, for example, taught
by the Waggoner reference for the conventional sprayer
