Abstract: In the representative embodiments described in the specification, a direct connect pressure tester arrangement has a saddle which is clamped to a pipe which may contain fluid under pressure and has a drill guide with an opening extending perpendicular to the wall of the pipe, along with a resilient member held against the outer wall of the pipe. A crosspipe is attached to a bushing mounted in the saddle and a valve is attached to the crosspipe in axial alignment with the bushing with a drill supported in axial alignment on the other side of the valve. A pressure gauge is mounted in a perpendicular passage of the crosspipe and a drain valve is attached to the cross pipe in axial alignment with the pressure gauge. After the pressure tester has been mounted on the pipe to be tested, the valve adjacent to the drill bit is turned to the open position and the drill bit is moved through the valve and the drill guide and operated to drill a hole in the pipe.

Abstract: In the representative embodiments described in the specification, a vertical sidewall sprinkler arrangement has a deflector supported from the junction of a pair of frame arms of the sprinkler and arranged to direct water in a generally horizontal direction. The deflector has a planar central portion substantially perpendicular to the sprinkler axis and extending in a direction parallel to the plane of the frame arms of the sprinkler on one side of the sprinkler axis; a first angled portion on the opposite side of the sprinkler axis, bent at an angle of about 50° from the planar central portion toward the sprinkler; and second and third angled portions extending outwardly from the planar central portion of the deflector and from the plane of the frame arms and bent toward the frame arms at an angle of at least 30° from the planar central portion.
