10 gypsum board, on the market, and the term wall board as herein used is understood to include all types of wall coveringto which the several features of the invention are applicable. Such wall board is usually manu- 1 factured in lengths to extend from the floor to the ceiling and is generally of a width which is a multiple of the spacing between the framing timbersof the building, which is usually 16 inches.

Each sheet of wall board must be nailed along each edge and along any framing timbers across which such sheet extends. When wall board is used as a side wall of a building the specifications as to nailing can be followed without the addition of any extra framing, as the studs extend along the edges of the sheets and the plates of the building frame extend across the top and bottom edges, thereby providing nailing support for the 1'90 sheets of wall board around their entire perimeter.

hen wall board is applied to a ceiling it is nailed directly to the joists where the joists engage it. At the ceiling angle, formed $5 at the intersection of the joists and the plate sin-mounting the studding defining the side wall of a room, the edge of the wall board that extends parallel to the plate and across the ceiling joists has no timber under it to 4.0 which it may be nailed. To prevent the wall board from warping along the ceiling angle, and to furnish necessary support for it, nailing headers are placed between the joists above the edge of the wall board. The ine5 sert-ion of nailing headers is expensive by reason of added labor caused in part by their inaccessibility which makes correct fitting and nailing difficult. They are often so insecurely fastened that the subsequent driving into them of the nails holding the wall board 1928. serm No. 269,810.

loosens them and forces them out of place.

In securing the nailing headers they must be toe-nailed in place. i

I provide'a reinforcing device for application to a frame structure at the joints between adjacent sheets of building material, elther atthe ceiling angle or at an intermed ate angle of a wall or ceiling. The reinforcing device extends across and is secured to a plurality of the framing timbers at the joint, for 1 supporting the edge of the sheets of wall board without the necessity of providing nailing headers. The application of the reinforcing device to a frame structure is much quicker, requires less labor, fewer nails, and

results in a better and stronger joint than is obtainable by the use of nailing headers.

At the ceiling angle the reinforcing device is also used to prevent the formation of a crack between the sheets of wall board upon the settling of the building frame, or the shrinking or warping of the frame. The reinforcing device also resists the separation of the various framing timbers by tying them together. i

The accompanying drawings illustrate certain preferred embodiments of the invention, in which Figure 1 is a perspective view ofa portion of a building structure illustrating the application of my invention to a ceiling angle;

Figure 6 is a sectional view showing the application of my invention to another type of ceiling angle;

Figure 7 is a perspective view of a reinforcing device for application to a ceiling prising a plurality of joists 4 constituting a ceiling, and a plurality of .studs 5 and cooperating plates 6 disposed at the top and bottom of the studs 5 and constituting a side wall. Sheets 7 of wall board are secured by nails 8 to the joists 4, studs 5 and plates 6. A reinforcing device 10 is mounted on one or more of the plates 6 and studs 5 in the included angle between the ceiling and side wall.

The reinforcing device 10, in the form of a reinforcing angle shown in detail in Figure 7, is provided with a flange 11, a strengthening and spacing rib 12 and a flange 14 extending substantially parallel to the rib 12 and spaced therefrom a distance substantially equal to the thickness of a sheet of wall board. In applying the reinforcing angle 10 to the framing timbers, the flange 11 is secured by small nails 15 to the plates 6 and a plurality of studs 5, with the flange 14 in engagement with the under surfaces of the joists 4 but free therefrom.

The length of the reinforcing angle 10 may be varied as desired. In general I prefer that its length shall be a multiple of the standard spacing of the joists and other timbers, that is 16 inches, in order that it may act as a tie between a number of the timbers for preventing their separation. After the reinforcing angle 10 is in place, the sheets 7 of wall board are applied to the studs 5 with thevrib 12'serving as a spacer against which the upper edges of the sheets 7 abut.

The sheets 7 are secured to the plates 6 by certain of the nails 8 which also extend through the flange 11. The edges of the sheets of wall board 7 applied to the joists 4 are inserted into the space between the rib 12 and the flange 14. The ends of the sheets 7 inserted into the reinforcing angle 10 are left free from the joists 4 for a distance from the ceiling angle in order to prevent opening of the joint, as hereinafter described.

By reason of the support given the edges of the sheets of wall board secured to the joists 4 by the rib 12 and flange 14 it is unnecessary to provide nailing headers between the several joists 4. This results in economy of time, labor and material. The reinforcing angle also results in a perfectly true ceiling angle as it prevents warping of the edges of the sheets and does not depend upon nailing headers which are apt to become loosened in service. After the sheets of wall board 7 are in place, the joint between them may be filled with filling material 16.

Referring particularly to Figures 2 and 3, upon the occurrence of a separation between the plate 6 and the joists 4 such as may be caused by the settling of the building, the free ends of the wall board adjacent the edge confined between the rib 12 andflange 14 as sumes a curved position, thereby keeping the joint at the ceiling angle closed rather than permitting the formation of unsightly openings and cracks. Upon a settling movement, the flange 14 curves to substantially the same extent as do the free ends of the wall board.

Referring to Figures 8, 9 and 10, the rib 12 may be spaced different distances from the flange 14 and is given a slope in order to permit its use with wall boards of different thicknesses. For example, the reinforcing angle shown in Figure 8 may have'a distance a0 between the lower surface of the flange 14 and the tip of the rib of 1/2 inch, and the distance a?) from the base of the rib to the lower surface of the flange 14 of 7/16ths of an inch, in which case the supporting angle is adapted for use in connection with sheets varying from 7/16t-hs of an inch to 1/2 inch in thickness.

In Figure 9 the distance ac is shown as 7/16ths of an inch, and the distance ab as 3/8ths of an inch; while in Figure 10 the distance ac is shown as 4/16ths of an inch and the distance a?) as 3/16ths of an inch. It is to be understood that the foregoing examples are given by way of illustration and are not to be construed as limiting the invention to any particular thickness of sheets.

In Figures 4 and 5, the invention is shown applied to a sharp roof where the sheets of wall board 7 are supported by rafters 21 that meet to form the ridge of the roof. A reinforcing angle 22 is secured by nails 24 to one set of rafters and extends beneath the sheets of wall board carried between adjacent rafters. The reinforcing and spacing rib is elim- 26, I provide a reinforcing angle 27 provided with a spacing rib 28 having a hooked portion 29 that underlies the surface of the sheets of wall board carried by the rafters 25. The wall board carried by the joists 26 is tapered for insertion between the upper surface of the rib 28 and the flange 30 of the reinforcing angle attached to the joists 26. Filling material 29 may be applied to the finished joint, if desired.

The material of the several reinforcing devices shown in Figures 6, 7 8, 9, and 10 is preferably of relatively light gauge metal through which nails can be readily driven,

and which has the desired flexibility to perdeparting from the spirit or scope of the appended claims.
