Appeal No. 97-2906
Application 08/367,837
articulated by appellants and the examiner. As a consequence of
our review, we have made the determinations which follow.
Turning first to the examiner's rejection of
independent claim 1 under 35 U.S.C. § 103, we note that this
claim is directed to a spray head for use with a spray gun having
passages in a spray gun body for delivering fluid and pressurized
air to said spray head. The spray head is identified by the
reference character (14) in appellants’ Figure 1. The spray head
is further defined in claim 1 on appeal as being “adapted to be
detachably mounted on the spray gun body,” for example, by the
retaining ring (16) seen in Figure 1, and as including a fluid
discharge orifice (52), a fluid inlet passage (54, 55, 50)
“adapted to receive fluid from a passage in the spray gun body
and to deliver such fluid to said fluid discharge orifice,” a
valve surface (at 51) adapted for cooperating with a trigger
operated valve needle (53) to form a trigger operated valve for
initiating and terminating the discharge of fluid from said fluid
discharge orifice, and a valve (25) mounted in said spray head
upstream of said valve surface (at 51) which serves to limit flow
of fluid to said fluid discharge orifice when the trigger
operated valve is open.
