Abstract: A cone and clamp assembly for a screen assembly comprises a substantially vertical supporting member about which a screen can be wound/unwound, a cone associated with at least one end of the supporting member and rotatable with the supporting member and at least one line member that can be wound onto and off the cone. The cone and clamp assembly comprises a clamp configured to hold the at least one line member relative to an external surface of the cone in an engaged position during transportation of the screen assembly or prior to operation of the screen assembly, a drive plate engaged with a pivot pin of the clamp, a cone plate coupled to the cone through the drive plate and the clamp, and an adjustable element coupled between the cone plate and the drive plate. Adjustment of the adjustable element in a first direction rotates the clamp toward the external surface of the cone and adjustment of the adjustable element in a second direction rotates the clamp away from the external surface of the cone.

Abstract: A pull across screen assembly has a flexible screen member (e.g. flymesh) wound about a vertical rod positioned at one side of the opening. A line member arrangement is attached to the front of the screen member and part of the line member winds about a tapered drum which is positioned on top of rod and which rotates with rotation of the rod. The arrangement allows the screen member to be tensioned and also to be balanced as it is pulled across the opening.

Abstract: A flexible screen material can be cut out of square, or part of the screen frame can be formed out of square such that when the screen is fitted to the screen frame, there is less sagging.
