ABSTRACT:
A heddle frame which has a pair of rectangular hollow metal cross rails, a pair of heddle bars associated with the cross rails for supporting heddles and a pair of end braces connected to said cross rails and said heddle bars and two or more connections between the cross rails and the heddle bars intermediate the end braces. The connections between the heddle bars and the cross rails comprise a hanger which may be formed of a synthetic polymeric material which is rigid, has a first portion which extends into an opening in the bottom of the hollow cross rail, and a second portion which is attached to the heddle bar. The upper portion of the hanger has a closed rectangular opening extending through it into which is fitted a metal insert of substantially the same thickness as the upper portion of the hanger. When the metal insert is placed within the hanger and the hanger is located within the hollow space of the rail, the metal insert is rigidly connected to the walls of the cross rail by means of spot welds, rivets or the like. It is essential to note that the width of the hanger is less than the width of the opening through which it extends into the rail and that the width of the closed opening within the upper portion of the hanger is greater than the width of the metal inserts. These features permit limited relative movement between the hanger and the metal inserts during stress upon the rail or the heddle bar.
