Abstract: An elongated steel member for diagonal attachment to and the bracing of the studding in a building wall without any notching of the studs preliminary to the use of the wall and before it has an outer sheathing mounted thereover. The brace is thin enough at its points of contact with the spaced apart building studs to permit an overlay of an outer wall to the studs without bulging. The formed and shaped brace is relatively deeply ribbed at its locations disposed between the studs and is either flat or relatively extremely shallow edge ribbed at the areas of contact with the studs to enable the brace to be relatively rigid throughout its length and giving the brace both compressive and tensile strength in its reinforcement of the wall.

Abstract: A device for cornerwise interlocking or clamping together elements, said device comprising a base plate mounting two abutments upstanding from said plate, and a supporting means parallel with said abutments, there being movably mounted on said supporting means an angular pressure plate and pivoted upon a transverse pin in a slot in the supporting means an excentric having a lever, said excentric applying when swung to a clamping position a pressure on the pressure plate for the movement of same towards the abutments.
