ABSTRACT:
A substantially tubular housing houses a swivel unit proximate one of its ends and a tailpiece proximate the other of its ends; with a relatively strong spring disposed therebetween to urge each unit against its respective housing end with sufficient pressure to retain each such unit as selectively positioned. A swivel seat washer is disposed between the spring and swivel; while a pair of washers, one plastic and one brass, are disposed between the spring and tailpiece. The swivel unit includes an extension with external threads and flat sides that cooperate with flat sides of an opening in the housing end and through part of the sidewall of the housing; the flat sides of the extension and of the housing opening coacting to restrict rotation of the swivel to ninety degrees of rotation about a first axis of rotation. The tailpiece is disposed within the housing to rotate about a second axis of rotation and is formed with an enlarged end that is retained within the housing and a reduced end that extends out through the other end of the housing. The inner wall of the housing at said second end is counterbored to provide a clearance space between said enlarged tailpiece end and the inner wall of the housing but for less than the full coextensive length of the two. The shoulder formed in the inner wall at the end of the counterbore is champhered to minimize, if not eliminate, a pressure point between the tailpiece and housing at this location. Stop means are provided to restrict rotation of the tailpiece to almost, but less than 360.degree..
