Abstract: The present invention comprises an improved mounting device incorporating two set screws acting upon two separate axially spaced-apart conical portions of an anchor bolt to produce a lateral "wedging" force which anchors the door handle securely in place against the door stile. The anchor bolt is secured in a hole drilled in the door by turning the threaded shank of the bolt into an internally-threaded rivet set into the hole. A door pull is inserted over the anchor bolt through a bore in the door pull, and a counter bore fits over the flange of the internally-threaded rivet to permit the door pull to bear directly against the door stile. As the two set screws are tightened into threaded holes in the bottom of the door pull, the beveled tips of the set screws bear on the conical surfaces of the anchor bolt, creating a lateral wedging force which moves the door pull toward and against the door stile.

Abstract: A cleanout plumbing fitting with two telescoped cylindrical cast parts, the internal part bearing a split ring lodged in and projecting from a cast-in one-turn helical groove to form a male thread; and the external part bearing three equiangularly spaced elongated elements each having a similar series of notches spaced corresponding to the groove pitch with the series successively offset by one-third pitch, forming an interrupted female thread engaged by the male thread for adjustability of the telescoped parts, the latter advantageous even with a cast male thread.
