Abstract
A siphon tube assembly for papermaking dryer drums having a threaded rotary elbow connection between support and siphon tubes permitting the tubes to be selectively oriented by rotation of the elbow connection between an installation position wherein the tubes are in general alignment and an operative position wherein the tubes are angularly related. In a preferred embodiment, the siphon tube is braced in rigid engagement with the interior of the dryer drum for use as a rotating siphon, it being also contemplated that the present elbow joint may be embodied in stationary siphons. The elbow joint provides an operating keyway accessible through the interior of the support tube for manipulating rotation of the elbow joint without requiring the use of handholes or manholes in the dryer durm.
