This spacing of the boards from the studs w; 5 also greatly lowers the sound transmission of a wall over'a wall in which the boards lie in face abutting position against the studs. As shown in Figs. 11-13 the attaching member 21 may be moved to any position intermediate the full line position and the dot-and-dash position so that as the frame member 32 warps or twists the attaching member 21 provides a yielding connection to prevent cracking of the plaster layer 25. In the form of clip shown in Fig. 14, a special attaching member 21a is provided withan outstanding flange 34 to engage the face of stud 32 andprovide a greater distance between the inner board face 35 and the stud, thus more effectively preventing stud marks on the exposed plaster surface. In the form of clip shown in Fig. 15, an attaching member 36 is pivotally secured to a clip body 31 by means of pivot pin 38. An outstanding flange 39 is formed on the member 36 and is adapted to ,be bent around a steel channel 40 or other metal section for attachment purposes.

It will be seen that the clips described serve to yieldingly attach the boards 23 to the frame members in the field, or main expanse of the wall or ceiling. Another important feature of my invention consists in providing free floating corners in which the boards are disconnected from the frame membersat the corners of the room to permit free expansion and contraction and eliminate corner cracks. For this purpose, I provide a corner clip 42 (Fig. 9) presenting channels arranged 'at right angles to receive the edges of plaster boards at the comer of a room. The body 43 of the clip 42 is provided with a right angle flange 44 along one edge, and finger flanges 45 along the other edge. Between the flanges 45, are L-shaped flanges 4B, the entire structure loosely and yieldingly connecting the adjacent edges of building boards meeting at a 90 angle, either interior or exterior. The corner clip 42 is not secured to corner frame members 48 but merely lies in abutting relation thereto. These corner clips are useful for erection purposes to support the boards while they are being put in place. Were it not for this function in aiding in erection, the corner clips 42 could be omitted and the boards left entirely unsecured to the comer stud to make a corner board construction which is entirely free to permit expansion and contraction of walls and ceilings without forming cracks in the plaster at the corners of a room. The corner clips 42 may be used in the interior corners of the room as shown in Fig. 8, or on the exterior corners of the room as shown in Fig. '7. In either case, Comerite or corner reinforcing is unnecessary to prevent corner cracks.

In the form of modified construction shown in Figs. 2-8, inclusive, the boards 23 are nailed directly to the studs 32 in the field of the walls and ceilings by nails 49, but the nails are entirely omitted within about 14 inches of the corners,of the room so as to provide this corner floating of the boards to prevent corner cracks in the plaster. In either the preferred form of full floating construction shown in Fig. 1 or the modifled form of construction, the boards extend transversely of the studs and the ends of the meeting in 'a haphazard manner between the studs, waste of boards due to cutting is reduced to a minimum, being only necessary at the corners of a room where nailing to the studs is prefor windows.

I would state in conclusion that, while the illustrated examples constitute practical embodiments of my invention, I do not wish to limit myself precisely to these details, since manifestly the same may be considerably varied without departing from the spirit of the invention as defined inthe appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

, 1. In a building construction, a plurality of spaced frame members for supporting walls or ceilings intersecting at corners, building boards secured to said frame members in the field of said walls or ceilings, said building boards being unattached to said frame members at said corners and for a substantial distance from said corners, means for connecting said boards together at said corners and a layer of plaster on the exposed face of said building boards, said plaster being characterized by freedom from corner cracks.

2.
