ABSTRACT:
A selectively sealing drain fitting includes a tubular drain body having a spider in the lower end thereof. An upwardly extending rectangular post is joined to the center of the spider, and is provided with a lateral slot in one face thereof and an oblique camming surface directly superjacent thereto. A drain sealing cover is provided with a downwardly depending hollow tubular portion which is received about the rectangular post and maintained in an eccentric disposition thereabout by an eccentric dog extending laterally from the upper end of the post. A compression spring disposed within the tubular portion of the drain cover biases the cover upwardly, and a latch pin extending laterally through the tubular portion of the cover engages the camming surfaces and the slot in the post in detent fashion. A laterally extending spring within the post biases a ball which is axially aligned with the eccentric dog to impinge on the inner surface of the tubular portion of the cover and maintain exact parallel eccentric alignment of the tubular portion and the rectangular post.
