LEWIS E. CURTIS, OF WARREN, OHIO, ASSIGNOB TO THE YOUNGSTOWN PRESSED STEEL COMPANY, OF WARREN, OHIO A CORPORATION OF OHIO. I

CORNER BEAD.

Application filed May 25, 1921. Serial No. 472,569

To all whom it ma concem:

Be it known that I Lnwrs E. CUnrIs, a citizen of the United dent of Warren, in the countyof Trumbull and State of Ohio, have invented certain new and useful Im rovements in Corner Beads, of which the ollowin'g 1s a spec1- fication.

My present invention relates to corner beads such as are used by plasterersto protect angles of plastered walls, and aims to provide a construction WhlCh w1l1 be s mple and economical in manufacture, which will have a strong and well braced corner 16 head and in which ample provision Wlll be made for the keyin of the plaster.

The invention inc udes the novel features of construction and arrangement of parts hereinafter described and particularly de- 20 fined by the appended clalms.

My invention is illustrated in the accompanying drawing, in which:

Figure 1 is a perspective v ew of my improved corner strip.

26 Fig. 2 is a transverse sectional view showing the same as embodied in a plastered wall angle.

' Fig. 3 is a sideview.

Fig. 4 is a section on line 4-4 of-Fig. t3. Referring by reference characters to th1s drawing, my corner strip is shown as comprising a corner bead 1 preferably of rounded formation carried by the narrowweb portions 2 from the supporting sheets 5 3, the whole being formed by stampin or pressing from a single sheet .of metal. he portions 2 are brought into proximityv or contact with eachother, the diameter of the head and the width of these portions 2 cor- 4 responding to the thickness of the plaster.

he supporting sheets or wings 3 are provided with openings 4 for the passage of nails 5 designed to secure the corner strip to the wordwork, as illustrated in Fig. 2.

In order to brace the corner bead and also provide for efl'ectively keying the plaster States, and a resi adjacent to the bead, raised brid e pieces 6 are arranged, extending prefera 1y from the base of the bead to suitable points in the supporting sheets, and these bridge pieces are formed integral by slitting the a sheet metal of which the corner strip is made on parallel as clearly shown. in the drawings. The raised bridge pieces provide spaces beneath them into Which'the plaster, shown at -7 in Fig. 2, passes, forming an effective ke Such a strip as above described would be very readily and economically manufactured by the use of dies for stamping or pressing the sheet metal into the desired shape.

Having thus described my invention what I claim is: a

1. A plasterers corner strip having in combination, a corner head, support elements, diverging attaching elements and bracing members extending from the head, above the junction of the supporting'elements and attaching. elements, to the attaching elements remote from said junction and out the plane of said member.

2. A plasterers corner strip having in combination, a corner bead member, web members connecting the bead and diver ing attaching members and bracing..mem%ers, connecting the bead and attachin members and disposed out of the plane of t e attaching members.

3. A plasterers corner strip comprising a tubular bead and diverging supporting sheets connected thereto by adjacent web portions, the whole being formed of a single sheet of metal, portions of the sheets and webs being slit' along parallel lines with portions of the metal between such slits pressed upward from the planes of the sheets.

In testimony nature.

whereof, I afiix my sig- LEWIS E. CURTIS.
