MITER FOR SHEET METAL GORZN'ER BEADS Application filed Angust 6, 1930. Serial 110.473/168.

, This invention relates to corner miters for corner beads and screeds, and more particularly to a miteroint forming connection be-.

tween meeting angularly-related metal cor-,

- -5 ner beads, or screeds.

The primary object of theinvention is to provide a miter-forming angles formed at the adjacent ends of right- 7 angularly related corner beads of so-called 1 bull-nose type, as about uncased window and door openings in walls, wall niches, and the like, which. device complements said beads and forms at the angle between the latter a .continuous exposed surface.

A further object is to provide, in association with the adjacent right-angularly sheared end of right-angularly related corner beads of that type commonly employed as a trim and plaster gauge in external angles of uncased wall openings, a simple and inexpensive connection or attachment whereby is formed between such beads a close-fitting miter-like joint.

' In describing erence is'herein the invention in detail, refhad to the accompanying Figure 1 is aview in front elevation illustrating the invention applied to the adjacent ends of angularly related corner beads disposed about a window opening;

e same, the section being taken on line 22, Fig. 1, withthe plaster applied to the inner side wall and to the window sill;

Figure 3 is a similar section on Fig. 1; Figure 4: is aninner face perspective view of the corner miter; V

Figure 5 is an outer face elevation of the same; and

Figure 6 is a section on line 6-6, Fig. 5.

Referring to said drawings, 1 and 2 designate right-angularly related sheet-metal corner beads of the bull-nose type commonly employed in the outer corner angles formed by meeting interior plastered walls of buildings, such beads being used both as a protective trim and as a depth gauge for the plaster. As herein shown, said cornerbeads 1' and 2 are applied to the faces of the wall defining a line 3-3,

device for use in ire 2 isea sectional elevation of the window opening, but it will be understood that this disclosure is merely such beads and the present invention being applicable in numerous other'places. One of said beads, as the head 1, is attached to the wall, or to the lath 3 of suchwall, with an end thereof, or a portion of such end, more 7 or less closely abutting the lath et'of the adj aoent wall defining the window opening, as shown in full lines in Fig. 3 and 'as is indicated in dotted lines in'Fig. 1, said end being cross-sheared at a right angle to the length of the bead. The associated bead 2 has fitted closely within that end thereof which forms an angle with'said bead 1 the tongue portion f of a false corner miter 5. Said miter is formed of a single piece of sheet metal'and comprises, body 5 of arcuate form in cross section which conforms both in widthand shapeto the exposed face of the head portion of the bead2 for forming a continuation of the latter, as shown in Figs. '1 and 2.

The tongue 5, toward its end, is shapedto conform to the curvature of the inner wall ofthe head portion of the beadandis adapted for'having its opposite lateral edges received within the channels Gformed interior-1y of and at oppo-- site sides of said head portion. -Further, said tongue is inwardly offset with respect to the body 5 of the miter, therebyto form a shoulder 7 against which'theadjacent end of the head 2 may seat, or abut, and which, therefore, limits the extent to which the miter may telescope with respect to said bead. The body 5 tongue 5 in a diagonally inclined edge"8 which iscurved to conform substantially to the shape of thethereby engaged surface of 1 for formingwiththe the head of the bead latter a line. joint of'miter form, asis most clearly shown in clined at an angle of substantially degrees relative to the axial line of the miter, and, havinga slight concave curvature, is thus adapted to seat closely upon the head of the bead 1. Manifestly, the miter5 is applied to the bead 2 prior to mountingthe latterin illustrative,

in additionto the tongue v5", a

terminates at the end opposite the A'CORPORATION on 'nnLA-j 1 which is slightly tapered V Fig. 1. Said edge 8 is inplace, and said miter constitutes means for spacing said bead 2 relative to the bead 1.

The miter described provides an extremely simple and inexpensive form of device whereby, without alteration of the form of the ends of the corner beads as the latter are furnished by the manufacturer, two angularly related beads may be oined for forming a joint of miter form and appearance.

lVhat is claimed is 1. In combination with adjacent angularly related corner beads, a miter-joint forming connection comprising a body substantially corresponding in size and contour with the face portions of the heads of said beads and terminating at one end in a: diagonally i clined edge for conformably seating upon the head of one of said beads, and an integral tongue formed on the opposite end of said body occupying telescopedrelation to the adjacent end of the head of the other of said beads.

52. In combination with adjacent an 'ularly related corner beads, a miter-joint forming connection comprising body substantially corresponding in size and contour with the face portions of the heads of said beads and terminating at one end in a diagonally in clined edge which is curved to adapt it to seat conformably upon the head of one of said beads, and a tongue formed integrally on the opposite end of said body, said tongue being receivable within the head of tee other bead.

3. A miter for sheet metal corner beads comprising a sheet metal body of arcuate form in cross section, and a tongue formed on one end of said body and occupying inwardly offset relation to the latter, the opposite end of said body terminating in a diagonally inclined edge.

4. A miter for sheet metal corner beads comprising a body of arcuate form in cross section having at one end thereof a tonguelike extension which is inwardly offset with respect to said body, forming a shoulder, said body having its opposite end inclined at an angle of approximately d5 degrees to the axial line thereof.

5. In combination with corner beads disposed in right angular relation in a wall opening, one of said beads having an end thereof occupying abutting relation to one of the defining walls of the opening and the other of said beads having its adjacent end occupying spaced relation to said one bead, of a connection interposed between said ends and comprising a body substantially corresponding in size and contour withthe face portions of the heads of said beads and terminating at one end in a diagonal inclined edge which conformably seats upon the head of said one bead, the opposite end of said connection being received within the head of the said other bead.

6. In combination with corner beads disposed in right angular relation in a wall opening, one of said beads having an end thereof occupying abutting relation to one of the defining walls of the opening and the other of said beads having its adjacent end occupying spaced relation to said one bead, of a connection interposed between said ends and comprising a body substantially corresponding in size and contour with the face portions of the heads of said beads and terminating atone end in a diagonally inclined curved ed e whichconformably seats upon and complements the head of said one bead in the formation of a false miter joint, the opposite end of said connection'bcing reduced to form a tongue which is received within the head of the said other bead.

in testimony whereof, I affix my signature.
