' INSIDE CORNEIHBEAD.
Specification of Letters Patent. Patented Dec. 14, 1920,
Application filed August 14, 1916. Serial No. 114,688.
To all whom it may concern: v
Be it known that I, PHILLIP! F. FLAeoE, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in Inside Corner-Beads, of which the following is a specification, reference being had to the accompanying drawing. forming a part thereof. I j v This invention relates to sheet metal corner beads and plastering guides or gages for rentrant angles of plasteredwalls.
The main objects of the invention are to obtain true reentrant angles at the intersections'of'plastered walls, to facilitate the application of plaster adjacent to such angles; to avoid the cracking of the plaster in and adjacent to such angles by the shrinking, swelling, warping and settling of the wood or other ground work or foundation of the-walls; and generally to. improve the construction of metallic corner beads of this class.
It consists in the construction, arrangement and combinationof parts as hereinafter particularly described and pointed out in the claims.
In the accompanying drawing like characters designate the same parts in both fig uresl Figure 1 is a cross section on the line 1--1, Fig. 2, of a corner bead embodying the invention as applied to intersecting plastered walls. and Fig. 2 is a perspective view of a portion of the bead by itself as viewed from the inner side thereof. I
The head consists of a continous strip of sheet metal formed integrally with spaced or separated nailing or attachment wings a, disposed at an angle to each other corresponding with the angle formed by the walls to which the bead is to be applied. inwardly bent offsets or oflset portions b, substantially perpendicular to the wings. and oppositely folded gage flanges a, continuous with the inner meeting edges or portions of the offsets and forming a reenerant angle whose sides are parallel with the wings. The offsets 7) form an angular longitudinal recess in the back of the bead directly behind the flanges c and opposite the corner angle formed by the intersection of the walls to which the bead is applied. The offsets 6, which are brought together or meet flanges, as shown in Fig. 1.
at or adjacent to their junction with the folded flangesc. facilitate the springing of the wings a to readily adapt them to the lath (l' or other foundation to which the bead and plaster c are applied, as shown in Fig. 1, and
the recess 7' formed by theoffsets in the back of the bead, leaving a'quadrangular space between it and the lath (l or other plaster foundation, greatly facilitates placing and fastening the bead in position as it avoids contact with the lath d or other plaster foundation at the angle formed by the intersecting walls where obstructions such as splinters, are apt to occurin the rough unfinished foundation work'fcr the plaster. This recess or space also allows for the formation of clenches on the coating of plaster, which is pressed in applying the same, through openings 1) formed in the wings a, and extending into the offsets b, as shown. The folded flanges c, for a trowel or other instrument used in applying the plaster, and determine the proper thickness of the coating, which is applied flush with the inner faces ofthe The folding of the metal to form the gage flanges, which are exposed on their inner faces flush with the pastor, forms a comparativelystitf reentrant angle, which will maintain its true shape, springing or yielding of the offsets b permitting the wings a to conform or adapt themselves to any shrinking, swelling. warping or settling of the lath or other foundationto which the bead is attached, without causing the plaster to crack at or adjacent to the bead. The recesses between the wings a and the overhanging flanges 0 parallel therewith, receive and hold the plaster and permit the adjacent coatings separated by the intervening parts .of the bead, to slip or move relatively to each other in. accordance with relative movement of the intersecting foundation walls, without cracking, breaking or injuring the plaster or bead. The offsets b can bend or spring from or toward each other. to allow for any ordinary shrinking. swelling, warping or settling of the wood or other ground work for the plaster, without cracking the plaster or affecting its attachment to the ground Work.
Each of the wings (I of the head is preferably cut or formed into cars It. separated from one another by corresponding indenform gages or guides tations alternating with the ears and indentations of the other wing, as shown in Fig. 2, sojthat the ears of other beadsmay be cut from the indentations on either side or both sides or each bead with the least possible waste of material;
The bead is cut and rolled or pressed into the required shape in continuous strips or sections of any desired'length.
The wings (L or ears hare formed with holes 2, for nails j, or the like, by which the bead is fastened to the lath and stud: ding or other-ground work for the plaster, as shown in Fig. .1. I Modifications in details ofconstruction of the bead may be made without departure from the principle and scope of the invention as defined in the following claims. I claim; v
' 1. An inside corner bead consisting of a continuous stripof sheet metal formed inte grally each other at their adjacent edges by a clear space and disposed at an angle to each other corresponding with the angle formed. by theintersection of the walls to which the bead is to be applied, inwardly bent oflset portions substantially perpendicular to the wings, and folded two-ply gage flanges parallelwith and overhanging the wings and forming a reentrant angle at their iners ction." v
2. An inside corner bead consisting of a e ontinuous strip of'sheet metal formed integrally with attachment wings separated {from eachother at their afcl 'ear space and disposed at an angle to -.'each other corresponding with the angle formed by the intersection of the walls to which the bead is to be applied, inwardly bent offsets substantially perpendicular to with attachment wings separated from adjacent edges byv the wings, brought together along their inner edges and forming an angular recess in the back of the bead, and oppositely folded two-ply gage flanges overhanging and substantially parallel with the wings and formmg a reentrant angle at their intersection.
3. An inside corner bead consisting of a continuous strip of sheet metal formed integrally with attachment wings separated from each other at their adjacent edges by a clear space and disposed at an angle to each other corresponding with the angle formed by the intersection of-the walls to which the head is to be applied, inwardly bent ofl'sets substantially perpendicular to the wings, brought together along their inner edges and forming an angular recess in the back of the bead, and oppositely ti folded two-ply gage flanges continuous wi the inner edges of the offsets and formin reentrant angle whose sides arevparallel with and overhang the wings, formed with clench openings.
' 4. An inside corner bead consisting of a continuous strip of sheet metal formed integrally with attachment wings separated from each other at their adjacent edges by a clear space and disposed at an angle to each other and each comprising a seriesof ears separated from one another by corresponding: indentations alternating with the ears and indentations of the other wing, in-
wardly bent meeting ofi'sets substantially perpendicular to the wings and forming a longitudinal recess in the back of the bead, and oppositely folded two-ply gage flanges continuous with the meeting'portions of the offsets andtorming a reentrant longitudinal angle whose sides are parallel with and overhang the Wings.
