CORNER STUDDING FOR PLASTER-BQARD WALLS.

Application led March 25, 1924. Serial No. 761,681.

This invention relates to fireproof building wall constructions and more particularly to metal corner studding for plaster board walls.

An important object of my invention is to provide a simple and efficient metallic die formed supporting` stud for fireproof plaster' board building walls at their corners, that may be readily erected in position and which is provided with means for effectively preventing injury to their corners after plaster has been applied thereto.

Another object is to provide a metallic corner stud for plaster board walls in which the boards may be. readily secured thereto without employing nails or other similar securing means. i

In the accompanying drawings l have illustrated a. preferred embodiment of my invention, it being understood however, that no limitation is necessarily made to the precise structural details therein exhibited, but various changes, alterations and modifications may be resorted to within the scope of my invention when desired.

Fig. 1 is a fragmentary perspective view of my studding showing the corner edges of the plaster board of a building wall held secured together.

Fig. 2 is an elevation of my studding looking at one inner edge thereof.

Fig.' 3 is an elevation of my studding looking at the other inner edge thereof.v

Fig. /1 is a horizontal section of my studding taken on line 1 -1 of Fig. 2.

My studding includes two Istamped metal angle bars, namely an outer angle bar 1 and an inner angle bar 2. The bar 1 is stamped from a sheet of metal which is bent at 3 upon itself, forming a corner bead 1, and bent from the base of said bead at angles of 15 degrees forming angle members 5 and 6 extending` at right angles to each other, the member 6 being of greater width than the member 5. Member 5 is provided with a plurality of superimposed plaster key openings 7, and member 6 is provided with a plurality of superimposed plaster key openings 8. Bar 2 is stamped from a sheet of metal in the form of two angle members 9 and 10 extending at right angles to each other. Bar 2 is placed inside bar 1 with its -inside facing outwardly and its member 9 against the inside of member 6 of bar 1, and with the edges ofthe members 6 and 9 coinciding, so that the member 10 of bar 2 is spaced inwardly from member 5 of bar 1 at a distance sutlicient to permit the corner edge of a sheet of plaster board 11 of one wall of a tireproof building to lit between said members. Members 6 and 9 are spot welded together at their edges at suitable distances apart as indicated at 12. lrongs 13 are formed on the edge of member 1() of angle bar 2 at suitable intervals apart, which prongs are bent over the corner edges against the inner side of a sheet of plaster board 111 of the other wall of a iireproof building, the angle bar 2 forming a seat for the corner edge of the plaster board of the said other wall.

The lower end of the studding `may be mounted in a recess in the concrete door and the upper end 0f the studding may be mounted in a recess of the ceiling of a iireproof buildimT for securing the studding in position in the building.

Plaster 15 is spread over the outside of the plaster board 11, member 5 of the angle bar 1, and the adjoining side of bead 41 of if a. thickness coinciding with the outer edge of the bead, the plaster filling the openings 7 against the plaster' board in the form of keys. Plaster 16 is spread over the outside of the plaster board 11,`member 6 ofangle bar 1 and the adjacent vside of the bead 1 of a thickness coinciding with the outer edge of the bead, the plaster filling the openings 8 against the plaster board 11 in the form of keys. Plaster 17 is placed on the inner side of the plaster board 11 and plaster 18 is placed against the inner face of plaster board 141, covering the prongs 13.

The outer edge of the bead 1 receives all impacts against the corner of the wall and protects the sam-e.

What l claim 1. A metallic corner studding comprising an outer angle bar, an inner angle bar placed with one of its members against the inside of one of the members of the outer angle bar, means for securing said members together providing a space betweenthe other members of said angle bars to receive the corner edge of the plaster board of one wall, the

corner edge of the plaster board of the other wall resting in the inner angle bar, and

means for .securing the latter plaster board in said inner angle bar.

2. A metallic corner studding comprising an outer angle bar, an inner angle bar placed with one of its members against the inside of fifi one of the members of the other angle bar, means for securing said members together providing a space between the other members of said angle bars to receive the corner edge of the plaster board of one Wall, the corner edge 0l the plaster board Of the other Wall rest-ing in the inner angle bar, and prongs on the edge of the spaced member of the inner angle bar adapted to be bent over the inner edge ot the latter plaster board.

3. A metallic studding Comprising an outer angle bar formed with an external bead at its corner, an inner angle bar placed with one of its members against the. inside oi one of the members of the outer angle bar, means for securing said members together, providing a space between the other members of the angle bars to receive the corner edge of the plaster board of one wall, the corner edge ot' the plaster board of the other Wall resting in the inner angle bar, and means ior securing the latter plaster board in said inner angle bar.

4L. A metallic corner studding an outer angle bar.y an inner angle bar placed with one vof its members against the' Ainside of one of the members of the outer angle Comprising bar and said members being spot Welded together, in sueh position as to provide a space between the other members oit' said angle bars to receive a corner edge of the plaster' board ot' one Wall, the corner edge of the plaster board of the other Wall resting in said inner angle bari and means for securing` the latter plaster beard in said inner angle bar.

5. A metallic corner studding comprising an outer angle bar, an inner angle bar placed with one of its members against the inside oi one ot the members of the outer angle bar, means for seeming .said members together providing a space between the other mem bers of said angle bars to receive the corner edge et' the plaster board oi one wall, the eorner edge or the plaster board of the other wall resting in the inner angle bar, and means for securing the latter plaster board in .said inner angle bar, the members of the enter angle bar being provided With plaster :ey openings.

In Witness that l Claim the foregoing l have hereunto subscribed my name this 5th day of March, 1924.
