Abstract
Abstract This invention is concerned with a device for eliminating seams at the butt joints caused by the installation of contiguous wall boards in building construction. A bracket, having means for fastening to the studs, has a slightly recessed surface. The butting edges of the wall boards that are fastened to the studs are screwed down tightly on the recessed surface of the bracket. The wall boards, being somewhat flexible, form a concave outer surface slightly below the plane of the wallboard surface that is mounted on the stud. The concave area is taped and then filled with a selected filling material or a joint compound, bringing the new surface formed thereby back to the original plane of the wallboard. The bracket is permanently secured by the wallboard so there will be no movements, and the filling and taping procedure completely conceal the joint lines, so that the wallboard can be painted or wallpapered and will appear as one continuous surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
179 words
A device for eliminating seams between the butt joints of two contiguous sheets of installed wall board mounted on studs comprising, a front flat surface, a top surface extending at right angles to the rear of said front surface, a bottom surface at right angles to said front surface, below said top surface, said top and bottom surfaces converging towards each other, a first vertical section located at the closest point between said upper and lower surfaces and extending at right angles forward of said front surface, a first flange extending at right angles to said first vertical section and in the same plane as the front surface, a second vertical section extending forward of said front surface and parallel to said first vertical section, a second flange extending outwardly therefrom, and being in the same plane as the first flange, a third section extending upwardly from said top surface and in the same plane as said second section, a fourth section extending downwardly from said bottom surface and in the same plane as said second and third sections.
Claim 2
Independent Claim
179 words
A device for eliminating seams between the butt joints of two contiguous sheets of installed wall board mounted on studs comprising, a front flat surface, a top surface extending at right angles to the rear of said front surface, a bottom surface at right angles to said front surface, below said top surface, said top and bottom surfaces converging towards each other, a first vertical section located at the closest point between said upper and lower surfaces and extending at right angles forward of said front surface, a first flange extending at right angles to said first vertical section and in the same plane as the front surface, a second vertical section extending forward of said front surface and parallel to said first vertical section, a second flange extending outwardly therefrom, and being in the same plane as the first flange, a third section extending upwardly from said top surface and in the same plane as said second section, a fourth section extending downwardly from said bottom surface and in the same plane as said second and third sections.
Claim 3
Dependent Claim
27 words
A device as described in claim 1 wherein the dimension of the first and second sections are approximately one-fourth of an inch forward of the front surface.
Claim 4
Dependent Claim
50 words
A device as described in claim 2 wherein when two contiguous wall boards are screwed down into surface contact with the front surface, butt joints form a concave surface below the surface of the wall boards that are in contact with the front surfaces of the first and second flanges.
Claim 5
Independent Claim
57 words
A device as described in claims 3 whereby when the butt joint is taped and a filler material is placed over the tape in contact with the front surface and brought up to the level of the plane of the wall boards that rest on the said flanges, the seams caused by the butt joint is eliminated.
Claim 6
Dependent Claim
69 words
A device as described in claim 2 having means for securing the contiguous wall boards to the front surface, tape means for covering the seam created by the butt joints of said wall boards, and filler means for bringing the plane of the wall boards at the butt joints up to the level of the plane of the wall boards that are in surface contact with the said flanges.
Claim 7
Dependent Claim
42 words
A device as described in claim 2 having means for securing the first flange to the front surface of a stud, and means for securing the third and fourth sections of said device to the inside surface of the next proximate stud.
Claim 8
Dependent Claim
65 words
A device as described in claim 6 having means for securing the contiguous wall boards to the front surface, tape means for covering the seam created by the butt joints of said wall boards and means for bringing the plane of the wall boards at the butt joints up to the plane of the wall board that is in surface contact with the said flanges.
Claim 9
Dependent Claim
42 words
A device as described in claim 5 having means for securing the first flange to the front surface of a stud, and means for securing the third and fourth sections of said device to the inside surface of the next proximate stud.
Claim 10
Dependent Claim
51 words
A device as described in claim 8 wherein when two contiguous wall boards are screwed down into surface contact with the front surface, their butt joints form a concave surface below the surface of the wall boards that are in contact with the front surfaces of the first and second flanges.
Claim 11
Dependent Claim
57 words
A device as described in claim 8 whereby when the butt joint is taped and a filler material is placed over the tape in contact with the front surface and brought up to the level of the plane of the wall boards that rest on the said flanges, the seam caused by the butt joint is eliminated.
