UNITED STATES JOHN JOHNSON, OF NEW YORK, N. Y.

CORNER BEAID.

Application filed October 25, 1920. Serial No. 419,414.

To all whom it may concern:

Be it known that I, JOHN J oHNsoN, a citizen of the United States, residing at Bronx, New York city, New York, have invented new and useful Improvements in Corner Beads, of which the following is a specification.

This invention relates to a corner bead, and the object is to provide, in connection with a plurality of clips to be secured to the corner portion of a wall, a bead per se which shall include an outer curved element and inwardly turned flange portions, the edges of the latter being outwardly turned, so that the head when engaging the clips will be permanently and efl'ectively retained after the plaster has been applied to the wall.

lVith the foregoing and other objects in view, the invention consists in the novel construction, and formation of the elements comprising respectively the clips and the bead per se, and consists further in the. manner in which the elements are associated when in engaging or operative position.

In the drawings, Figure 1 shows the device in top plan, as embedded in a wall, or the plaster covering thereof Figure 2 shows the bead in front elevation, as it appears when in use; Figures 3 and at are details of the clip and the bead.

In carrying out my invention, I provide a plurality of clips to be connected with the corner portion of a wall, and suitably spaced, the clips being preferably about one foot apart. These clips each include a head having a flat portion designated 10, and a plurality of leg portions 11 and 12 provided with apertures 13, for securing the clips in position by nailing, or otherwise, prior to the placing of the bead in position.

The under side of the head is curved as shown at 15, and the curved portions each are provided with engaging devices 18 and 19 for retaining the bead in a positive and effective manner. These engaging devices are formed by upsetting the metal in the manner shown, whereby a simple engagement with the bead is provided, since each of the engaging devices contacts with one flange of the bead, and the central portion, or rather the edges of the central portion or head of the clip, contacts with the curved portion of the bead.

The bead includes acurved outer portion 20, the flanges 21 and 22, and the outwardly turned portion or flange 23 and 24. The portions 21 and 22 are in direct contact with the engaging devices 18 and 19 upset from the lower side of the head in the manner specified and are resilient. The outwardly turned flanges 23 and 24 are of course embedded in the substance of the wall when the plaster and calcimining are applied.

The bead is manufactured in length of sa yfrom six to twelve feet, and is regarded as being especially effective in serving the purpose intended.

What is claimed is:

In a device of the class described, anelement including a plurality of legs, a head, and outwardly turned resilient devices upset from the lower portion of the head, and a bead including a central portion, inwardly turned flanges and deflected edge portions,

the flanges of the bead being directly en I gaged on their inner sides by the under portion of the head and by the devices upset from the head, and the bead being locked to the head by the engaging devices. 7

In testimony whereof I aflix my signature.

JOHN JOHNS ON.
