' EXTERIOR comma CONNECTION FOR WALL nouns Filed May 51, 1930 F/GZ.
Patented May 12, 1931 UNITED STATES PATENT OFFICE EXTERIOR CORNER CONNECTION FOR WALL BOARDS Application filed May 31,
My invention relates to improvements in exterior corner connections for wall boards, which will render the joint invisible and, at the same time, reinforce the corners apex so that there is no danger of the edge becomright angles one to the other. The outer face of the boards 2 and 3 are provided with edge recesses 2 and 3*.
l and 5 are arms of a corner plate set at right angles one to the other and counter sunk within the recesses 2 and 3", the arms 41: and 5 being connected together at the apex of the angle formed thereby by a bead 6 extending longitudinally of the plate. The outer periphery of the bead 6 is in horizontal alignment withthe outer face of the wall boards 2 and 3 so that when the recesses 2 and 3 are provided with a filling and 2 and 3 a flush surface is formed extending from the face of the wall. board I to the extreme corner formed by the arms of the plates 4 and 5 and the bead 6.
The arms 4 and 5 of the plate are connected to the corner post 1 by nails 7 and 8 which extend through perforations 4 and 5 in the arms 4 and 5 through the recessed portion of the wall boards 2 and 3 into the post 1. Large perforations 9 and 10 are also formed in the arms a and 5 respectively adjacent to the bead 6 and opposite the hollow place formed between the wall board ends and through which the filling 2 and 3 is forced in order to key it as indicated at 11 and 12.

the securing nails 7 and 8 also aid to key the filler in place.
From this description it will be seen that I have devised a very simple construction whereby a joint is formed to provide a flush surface around an exterior corner, in such a way that the apex of the corner is reinforced so that it cannot possibly be broken or chipped.
What I claim as my invention is:
1. In a wall board corner connection, the combination with a corner post, of a wall board having a recessed outer edge placed against each outer face of a corner post, an angle plate the arms of which are counter sunk in the recesses, securing means extending through the arms of the plate, recessed portions of the wall board and into the post, and a plastic filler for the recess covering the arms of the plate.
2. In a wall board corner connection, the combination with a corner post, of a wall board having a recessed outer edge placed against each outer face ofa corner post, an angle plate the arms of which are counter sunk in the recesses, securing means extending through the arms of the plate, recessed portions of the wall board and into the post,
and a bead formed integral with the arms of the plate the exterior periphery of which is flush with the surface of thewall board, and a filler for the recess the outer face of which is flush with the surface of the wall board and the exterior periphery of the bead.
