Abstract: A sliding door installation in a doorway. Framed door panels are guided over threshold trackways and suspended from roller wheels in trackways at the top of the doorway. Corner brackets interconnect rails and stiles framing the door panels. Identical brackets interchangeably untilizable to carry roller wheels or floating guides interconnect the rails and stiles at the corners of the door panels. The brackets include three spurred lugs for securing the brackets to the rails and stiles. The rails and stiles are designed to be interconnected by the brackets to form a sturdy frame around the door panel edges.

Abstract: A trailer hitch including a remotely actuated grapple which is intended to grippingly engage the tongue structure of a trailer conveniently along the length thereof. The grapple is pivotally attached to support structure by a vertical pivot pin to facilitate turning the trailer. A pair of springs are interposed between the grapple and the support structure to yieldably urge the grapple toward a centered position when not connected to a trailer. The grapple includes serrated jaws for biting into the tongue. Also, lug structure disposed subjacent the jaws is included to pick up the tongue and support it in a towing position prior to the jaws being caused to grip the tongue. The lugs engage the lower surface of the tongue and slide freely towards the free end thereof as the towing vehicle is caused to move in a direction away from the trailer.
