Abstract: A harness frame for use in weaving machines includes a generally rectangular frame formed by top and bottom slats attached to side members. Heddle rods are carried by the slats wherein heddles are placeable onto or removable from at least one end of the heddle rods. A slide member is disposed on the side member adjacent at least one of the heddle rods. The slide member is movable on the side member between an open position wherein the slide member is displaced from the heddle rod so that the heddles can be slid on or off of the heddle rod, and a closed position wherein the slide member abuts against,the heddle rod and prevents heddles from being slid off of the heddle rod.

Abstract: A heddle frame has a pair of laterally extending slats and a pair of end braces connected to the slats to form a generally rectangular frame. An elongated opening is defined at least in the ends of the slats, and typically throughout the slat. A locking mechanism is configured to lock the end braces to the slats and typically includes a device housed at least in part within the slats. A corner sleeve member is adhesively fixed on the slats at the ends thereof directly adjacent to the end braces to structurally reinforce the slats at the position of the locking mechanism.

Abstract: A heddle frame for supporting a plurality of heddles includes a top rail and a bottom rail extending longitudinally relative to the frame. End members connect the top rail and bottom rail so as to form a generally rectangular frame structure. A heddle bar is supported on the frame structure wherein heddles are supported by said heddle bars in the frame structure. A center brace extends between the top rail and the bottom rail at a position between the end members for maintaining parallelism of the top and bottom rails. The center brace includes an elongated center portion and first and second flanges at opposite longitudinal ends of the center portion. First and second locking blocks are respectively attached to the top rail and the bottom rail and are configured to respectively receive the first flange and the second flange and to exert forces on the first and second flanges to create opposing torques thereon.

Abstract: A heddle frame for holding a plurality of heddles comprising a top rail and a bottom rail. Each of the rails has heddle supporting bars attached to them for supporting the heddles within the frame, and the top and bottom rails are held in parallel relationship to each other by end members attached to their adjacent ends. Intermediate the end members is a center brace which may be located in alternative positions within the heddle frame. Each of the rails has an opening to receive the centerbrace and to support it so as to maintain the parallel positions of the top and bottom rails. The holes within the rails are reinforced with steel reinforcing guide tubes which resist the wear of the centerbrace during the use of the heddle frame and protects the rails.

Abstract: A heddle bar having a cross-sectional profile for supporting heddles in a heddle frame. The heddle bar has a supporting rib for engaging a heddle bar support channel in each of the slats making up the heddle frame assembly in an interference fit therewith to make its removal difficult but not impossible. The heddle support bar is not bonded or glued to the slat.The heddle bar may be shaped to support any type heddle, and may be T-shaped or shaped to support J-shaped heddles.

Abstract: A heddle frame having a pair of hollow laterally extending cross rails and a pair of end braces connected to adjacent ends of the cross rails to form a rectangular frame. A quick release connection is provided between the end braces and the laterally extending cross rails which includes a connector which is fixed within an opening in the cross rail which has means for compressively gripping a projection which extends at right angles from the end brace. The projection has a width which is less than the width of the opening into which it extends and the connector is resiliently connected to the walls of the hollow rail to provide a connection between the end brace and a cross rail which is rigid when not under stress but which permits limited relative movement of the cross rails and the end braces whenever the cross rails are under stress.

Abstract: A heddle frame has a pair of laterally extending slats and a pair of end braces connected to the slats to form a rectangular heddle frame. Each of the connections between the slats and the end braces includes an elongated opening defined within the end of the slat. The end brace includes an inwardly directed expansion foot configured on and extending essentially perpendicular from the end brace and having a width so as to be slidable within the elongated opening of the slat. A releasable locking member is configured to lock the extension foot within the slat in a locked position and to release the end brace from the slat in a released position, the locking member is disposed through the extreme outward edge of the slat and extends into the elongated opening of the slat. In one embodiment, the end brace is secured directly to the slat by a threaded bolt extending through the extreme outward edge of the slat.
