2 Claims. (Cl. 'i2-1,21)
This invention relates to an improvement in corner beads and has for its object the provision of a corner bead which is so constructed as to eliminate the necessity of stripping in a piece oi 5 lath on arches, mullions, beams, pilasters, co1- umns, or the like, or between the corner and the adjacent surfaces of the wall where the corner is irregular or broken away in places, as corners sometimes are, and especially where hollow tile is used in the construction of the building.
Another object is to provide a corner bead of this character which has these advantages and capacities and yet is possessed of all of the advantages of the better known type of corner bead.
Other objects and advantages reside in certain novel features of `the construction, arrangement and combination of partswhich will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawing, forming a part of this specication, and in which:
Figure 1 is a fragmentary perspective view illustrating a corner bead embodying the present invention applied to an arch of a building; and
Figure 2 is a fragmentary perspective view showing a portion of a corner bead constructed in accordance with the present invention.
Referring to the drawing, it will be seen that the corner bead embodying the present invention comprises a narrow smooth nose 1 and diverging wings 2 of expanded sheet metal and which are formed as an integral part of the solid or imperforate metal which constitutes the nose.
The characteristic feature of the present invention resides in the provision of wings 2 which have the formation and dimensions of sheets rather than of strips. Wings having such characteristics are markedly advantageous in a number of respects in actual use. For example, as illustrated in Figure l, where two corner beads are employed in conjunction with the arch A of the building, one for each corner of the arch, the adjacent wings 2 completely cover the inner surr face of the arch and the necessity of stripping in a piece of lath in order to join the two beads is avoided. Furthermore, in connection with the arch or in connection with the corner of any other element of the building, where the corner is broken away as indicated at B the wings pro- 50 ject beyond the broken away portions and over` lie the normal or unbroken Wall surface and thus provide for the proper keying of the plaster notwithstanding the breaks B.
While the present invention is not restricted to any particular dimension as long as the wings have the substantial width requisite to give them the sheet-like character essential to the performance of their new functions it is contemplated that the wings shall not be less than ve inches wide.
While I have shown and described one strucl0 ture as illustrative of how the invention may be embodied, it is to be understood that various changes in the size, shape, form and arrangement of the parts may be made without departing from the spirit of the invention or thescope l5 of the subjoined claims.
The invention claimed is:
l. A corner bead of the character described, comprising a longitudinally extending cornerdelining metal nose for overlying a corner of a wall with which the bead is employed and wings of expanded metal on opposite sides of and extending along the length of the nose, said wings being in angular relation to the nose and permanently connected therewith, each of said wings being not less than flve inches in width whereby the wings are in sheet-like form to extend the plaster support afforded by the wings in the use of the bead to a substantial extent laterally beyond the nose of the bead: 1 30 2. A structural unit for defining the exterior corners and providing the plaster support for the wall surface between adjacent exterior corners in a building construction, comprising a pair of similar elements each including a metal corner bead having a longitudinally extending corner defining nose and two expanded metal wings on opposite sides of the nose and permanently connected therewith, the wings of each bead being angularly disposed with respect to the nose and extending laterally outwardly therefrom to provide plaster supports on opposite sides of the nose, one of the wings of each bead having a width not less than five inches, whereby said wings are in sheet-like form to span a wall surface of a width of six inches or more when two of said beads are arranged to denesaid corners and have their last mentioned wings meeting and cooperating between the corners to form a complete support for the plaster layer from corner to corner.
