INVENTOR John J. Manofs J, J. MANOFSKY CORNER BEAD Filed June 12, 1937 June 27, 1939.
Patented June 27, 1939 UNITED STATES CORNER BEAD John J. Manofsky, Warren, Ohio, assignor to National Gypsum Company, Buffalo, N. Y.
Application June 12, 1937, Serial No. 147,881
8 Claims.
This invention relates to a building element and more particularly to a corner reinforcing or securing element.
The article of the present invention is susceptible of general use in the building art but its principal application is when used at the juncture of intersecting walls. It has heretofore been contemplated to provide an elongate element of angular cross section for securement to the wooden or metallic reinforcing structure in a building where plaster, concrete or the like, is subsequently applied.
A building element of the type under consideration is illustrated in the patent to Clark No. 1,257,980 and my present invention embodies in one aspect improvements in acorner bead of the type there illustrated although the uses of the article of my invention and the novel principles therein embodied may be more general than are there' contemplated.
In constructing arched doorways, beams, windows and other structural details involving curving structure, a considerable amount of difficulty has been encountered in attempting to deform normally linear structural elements, which may be corner beads of the type shown in the Clark patent, in order that they may conform to the contour of the subject curve.
In one form of my present invention I so arrange and distribute the openings in a corner bead, which are normally provided for the reception of plaster or cement to key or anchor the plaster or cement to the structural framework, that curving of the corner bead may be accomplished without the usual tendency of the element to break sharply in one place when an attempt is made to curve the angular element longitudinally.
Other features and advantages contribute to the general efficiency and desirability of my new structural element for use both as a corner bead and as a structural element generally and will appear from a study of the ensuing description and from the claims.
In the drawing, Fig. 1 shows a lath and plaster wall construction with an opening having an arcuate portion employing a corner bead constructed according to the principles of my invention.
Fig. 2 is a horizontal cross sectional view taken approximately on the line 2-2 of Fig. 1.
Fig. 3 is a detailed perspective view of a short piece of my proposed corner bead, and
Fig. 4 is a development of. the blank used in the manufacture thereof.
Referring to Figs. 1 and 2 of the drawing the numeral Ill designates a series of the usual wood laths aflixed to a corner post II and, at other points, not shown, to the usual studding. As is best illustrated in Fig. 2, where lath walls in intersecting planes converge, a corner bead of angular cross section and having flanges I3 and I4 isused. In the illustrated instance the flanges and walls extend at approximately right angles to each other with one flange secured against each of the converging walls through nail holes l5 which are preliminarily formed in the corner bead.
To insure adequate anchoring of the plaster which is subsequently applied, I provide, a plurality of triangular openings for the reception of gobs of plaster which, after hardening, serve as keys or anchors to secure the plaster to the wall. These openings are arranged in a particular manner, and as a result of their arrangement there is provided a corner bead which may be curved to fit any archway or other curved corner construction, such as the one indicated at A in the Fig. 1.
The peculiar arrangement of plaster receiving openings referred to includes the provision in each flange of the angular corner bead of two rows of triangular openings l6 extending longitudinally thereof. One of the rows has a plurality of triangular openings placed with one side parallel to and closely adjacent the meeting line of the two flanges of the corner bead. 'The spacing of the triangular openings of this row is such that the remaining metal extending between the aligned sides of the triangular openings is of substantially less dimension than the length of the aligned sides of the triangular openings.
When curving of the corner bead is contemplated, slits l'l may be provided extending from the triangular opening of this row to the outer edge of the flange so that when an attempt is made to curve that flange in its own plane of extent, the only resistance offered by this flange of the element in the immediate vicinity of the triangular openings is the short marginal portion extending from the base of the triangular opening to the meeting line of the two flanges. Since these comparatively narrow marginal portions form more than one-half. of the total exv tent of any given length of corner bead, it will be seen that a satisfactorily accurate are or smooth curve can be produced even though the flexure occurs only in the regions of these narrow marginal portions.
With the arrangement and spacing of triangular openings employed, however, the narrower, joining portions connecting the triangular openings adjacent the meeting line of the flanges offer only a negligible resistance to the correct and facile curving of the corner bead proper even at points on the corner head which lie adjacent the connecting portions. The second row of openings IS in each flange. lies toward the outer edge of the flange and these openings are preferably disposed with one side of each extending parallel to the edge of the flange and adjacent thereto so that the apex of each triangle may extend toward and perhaps partially between the openings of the first row.
In the illustrated instance the apexes of the triangular openings of one row extend only a very-slight distance between the triangular openings of the second row, constituting, in efiect, two substantially adjacent rows of staggered openings.
.The outer edge of the flange and the sides of the triangles of the second row which extend parallel thereto form a marginal portion which is preferably of substantially greater width than the marginal portion lying between the sides of the first row of triangles and the meeting line of the two flanges of the element, this for the reason that a row of openings l5 for receiving nails or other suitable fastening elements and for reasons of increased structural rigidity.
It will be seen that the greater width of the outer marginal portion does not add to the difli- ,culty encountered in flexing or curving the member due to the presence of the slits l1 whose edges may separate to accommodate changes in length of the flange at that point.
The two flanges l3 and I4 may merge into an approximate elliptical corner bead I8. The major axis of the bead I8 is preferably coincident with a bisector of the angle of the flange and when so positioned, the axis of the bead l8 tends under bending stress in the plane of either flange, to assume a position at right angles to the plane of that flange whereby the bending stress, insofar as the bead is concerned, is exerted upon the minor axis of the bead and the resistance offered thereby is subsequently minimized.
It is to be understood that the specific dis-.
closure herein is merely exemplary and that the invention is to be regarded as in no wise limited excepting as appears from the appended claims.
What is claimed is:
1. A corner bead comprising an elongated me-.
tallic element of angular cross section, one leg of which has two parallel rows of aligned triangular openings therein extending longitudinally thereof with the openings of the inner of said rows hav-- ing a side adjacent and parallel to 'theapex of the angle and the openings of the outer of said rows having a side adjacent and parallel to the outer edge of said leg, and slits extending from the openings of the inner row to the outer edge of said leg.
