Abstract
The lateral support of the heddle frame is provided with a projection which is received in a complementary recess in the end of the frame stave. The upper surface of the projection is provided with a bevelled surface. A screw extends diagonally into the recess from the outer edge of the frame stave adjacent the lateral support with the central axis of the screw disposed perpendicular to the bevelled surface to prevent the withdrawal of the projection from the recess when the end of the screw is disposed in engagement with the bevelled surface. The projection may additionally be provided with a spring biased pivot disposed parallel to the length of the lateral support for automatic engagement in an aperture near the entrance of the recess upon partial withdrawal of the projection from the recess after the screw has been backed off from the bevelled surface to allow the lateral support to be pivoted away from the end of the frame stave to expose the corresponding end of the heddle rod for the addition or removal of heddles. A plunger may be provided in the aperture for ejecting the spring biased pivot to permit full removal of the projection on the lateral support from the recess in the frame stave.
