International Classification:

B43H 710

US Classification:

33480

Abstract:

An attachment for a framer's square which permits the framer's square to be self supporting on a flat, horizontal surface. The attachment has an elongated support bar with two clips which may be inserted over a blade of a framer's square. This attachment, when inserted on the inner edge of the framer's square, facilitates the scribing of a right-angle line to a rounded edge and when placed on an outer edge, permits the square to be free standing.

Abstract:

A shielded door assembly for a generally rectangular opening in the electrically conductive wall of a grounded building has an electrically conductive frame secured to the wall along three of the sides of the opening. A tubular frame is secured to the first frame along the three sides thereof. An electrically conductive threshold having a non-interrupted contact surface is secured to the tubular frame at the remaining side of the opening. An electrically conductive door stop is secured to a first edge of said tubular frame and extends outwardly therefrom and cooperates with the tubular frame and the first frame for defining a pocket. An electrically conductive tubular door rim is pivotally secured to said first frame and is adapted for pivoting between an open and a closed position. The door includes a first surface thereof adjacent the threshold and a plurality of electrically conductive resilient spring means are secured to the first surface for establishing electrical connection between the door and the threshold. A plurality of electrically conductive resilient springs connect the door to the pocket for thereby further facilitating electrical communication between the door and the building.
