Patent ID: 7618068

Claim:
A siphon elbow for pivotally connecting separate horizontal and vertical siphon pipes in fluid communication, the siphon elbow comprising: a monolithic horizontal body having a first, longitudinally-extending passageway defined therethrough between opposite first and second open ends, the horizontal body first open end connectable to an end of a horizontal siphon pipe, and a second passageway defined transversely through said horizontal body and intersecting said first passageway, said second passageway at least partially defined by opposite openings in the horizontal body; a monolithic pivot body having a passageway defined transversely therethrough between first and second open ends, the second open end being connectable to an end of a vertical siphon pipe, and the pivot body being freely rotatably supported within the second passageway of the horizontal body so as to permit the positioning of a vertical siphon pipe connected thereto between a first position, characterized in that the vertical siphon pipe is generally longitudinally aligned with the first, longitudinally extending passageway of the horizontal body, and a second position, characterized in that the vertical siphon pipe is aligned at an angle relative to the first, longitudinally extending passageway of the horizontal body; further comprising a locking retainer movable between a first position, wherein the pivot body can rotate in relation to the horizontal body, and a second position, wherein the locking retainer engages the pivot body such that the pivot body cannot rotate in relation to the horizontal body, and wherein further the locking retainer is biased towards the second of engagement with the pivot body; wherein the locking retainer is moveably disposed within the first passageway of the horizontal body and has a longitudinal passageway defined therethrough between opposite first and second ends to permit fluid communication between the horizontal body first passageway and the pivot body passageway, and wherein, in the second position thereof, the locking retainer second end engages the pivot body first open end such that the pivot body cannot rotate in relation to the horizontal body.
