CORNER FOR CORNER BEADS.

Application filed June 29, 1925. Serial No. 40,381.

This invention relates to improvements in corner for corner-beads, and more especially to such a corner adapted for use in connection with metallic corner-beads.

By the use of my invention it is possible to form the corner between adjacent strips of corner-bead accurately and quickly without requiring laborious fitting, adjusting or cutting of metal. B the use of my invention also, for exampfe, the right angle corners formed by the corner-beads around a window casing may be quickly and ac curately made.

My improved device is cheap to make and is neat and durable.

Other features and advantages of my invention will appear more fully as I proceed with my specification.

In that form of device embodying the features of m invention, shown in the accompanying di'awings, Figure 1 is a View in front elevation of my improved corner for corner-beads, Fig. 2 is a View taken as indicated by the line 2 of .Fig. 1, Fig. 3 is a View in side elevation of the corner piece itself, and Fig. 4 is a bottom view of the same.

As shown in the drawings, the corner-bead is made of a single strip of sheet metal curved longitudinally along its length at the center to form a bead proper 10 which thus presents a rounded transverse outer surface having elongated straight edges 11, llto provide the ground or gage to which the plasterer may finish his Work and further to provide means for straightening the plastered structure at the corners.

At the edges 11, the metal is bent back as indicated at 12 to partially overlap and lie parallel with the side margins Oil/11B bead portion 10. The portions 12 are preferably spaced from the side margins of the portion 10 a distance equal substantially to the thickness of the metal. The metal from the inner edges of the portions 12 is bent away from the bead portion 10, the two sides being substantially parallel for a short distance, to form the narrowed throat 13. From the inner end of the throat, the metal is bent outwardly to form the two side wings 14, 14, which lie substantially at right angles to each other and serve to attach the head to the structure to be plastered. These wings are provided with the holes 15, l'adapted to receive the nails 16 which may nail the corner-bead to the structure to be plastered. The wings are also provided with the usual perforations 17 having the flanges 18 which serve as keys for the plaster.

The corner piece itselfis shown in Figs. 3 and 4. This is preferably made out of pressed steel and it will be seen that this corner piece in cross-secti0n is substantially the same as the head portion proper of the corner-bead. The corner piece itself is indicated in general by 19. This piece comprises the corner portion proper indicated by 20 which forms a right angle for the corner-bead proper as shown. The portion 20 is provided at each end with an ear or lug 21 which is also curved transversely to conform to the curvature of the head 10. The lug or ear 21 of the corner piece is adapted to fit into the space between the bead portion 10 and the bent-back portions 12. The corner piece 19 is provided with a shoulder or oflset 22 where the ear 21 joins the corner portion 20. This oifset or shoulder 22 is substantially the thickness of the metal and is adapted to butt against the end of the bead portion 10 of the corner-bead and form a continuation thereof. (See Fig. 1.)

The corner piece 19 is preferably stifi' and rigid so that when the ears or lugs 21, 21 are in place in the ends of the cornerbeads, a stifi and rigid corner connection for the two corner-beads will be made. The ear 21 is adapted to fit snugly in the end of the corner-bead piece. It will be seen that by the use of my invention, a corner for corner-beads may be accurately and quickly formed without requiring any laborious cutting or fitting. If it attempted to make a corner between the two beads without the use of. such a corner iece it is necessary to do very accurate diagonal cutting and fitting of the two ends of the corner-beads in order to make the mitered corner. By the use of my invention, all such work is done away with.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invenloo tion as broadly as possible in vi'w of the prior art.

What I claim as new, and desire to secure by Letters Patent, is:

1. A corner-bead structure comprising; a corner-bead formed from astrip of metal bent longitudinally to provide a bead portion proper, gprtions of said metal being bent backwar y upon itself at the edges of said bead portion proper, thence inwardly substantially parallel to form a narrowed throat and thence away from each other substantially at right angles to form wings for attachment to a structure to be plastered; and a corner piece having a corner portion forming a right angle and adapted to form a continuation of and right angled connection between the two bead portions proper of two corner-beads lying at right angles to each other, said corner piece being provided at each end with an ear adapted to be inserted into the end of one of the corner-beads in the space between the head portion proper and the portions of the metal bent backwardly upon itself at the edges of said bead portion.

2. A corner-bead structure comprising; a corner-bead formed from a strip of metal bent longitudinally to provide a bead portion proper, ortions. of said metal being bent backwar ly upon itself at the edges of said bead portion proper, thence inwardly substantially parallel to form a narrowed throat and thence away from each other substantially at right angles to form wings for attachment to a structure to be plastered; and a corner piece having a corner portion forming a right angle and adapted to form a continuation of and right an led connection between the two bead portions proper of two corner-beads lying at right ang es to each other, said corner piece bead between the ing provided at each end with an ear adapted to be inserted into the end of one of the corner-beads in the space between the bead portion proper and the. portions of the metal bent backwardly upon itself at the edges of said head portion, said ear adapted to be held snugly in said -cornercorner-bead portion proper and the backwardly bent portions of metal at its edges.

3. A corner-bead structure comprising, a corner-bead formed from a strip of metal bent longitudinally to provide a bead portion proper, portions of said metal being bent backwardly upon itself at the edges of said bead portion proper, thence inwardly substantially parallel to form a narrowed throat and thence away from each other substantially at right angles to form wings for attachment to a structure to be plas tered; and a corner piece having a corner portion forming a right angle and adapted to form a continuation of and ri ht angled connection between the two bea portions proper .of two corner-beads lying at ri ht angles to each other, said corner piece emg rovided at each end with an ear adapted to be inserted into the end of one of the corner-beads in the space between the bead portion proper and the portions of themetal bent backwardly upon itself at the edges of said bead portion, said corner piece being provided with a shoulder or ofi'setat the juncture between the ear and the. corner portion, whereby the outer surface of said corner portion will lie flush with the outer surface of the head portion proper of the corner-bead.

In testimony whereof I have hereunto set my hand this 26th day of June, 1925.

CHARLES H. RICHARDS.
