Abstract
Abstract Mechanically fastened appended tabs invisibly secure common edge-abutting wallboard panels to common wood or metal framing members. The fastener appendants are spaced apart tabs extending from the back of and exposed beyond the vertical edges of the wallboard panels so as to be conveniently screw fastened. When screw fastened to common wall framing members, the appended tabs secure the wallboard panels slightly off the framing member front surface to permit offset appendant tabs of abutting wallboard panels to slide between the fastened wallboard panels and the framing members and be engaged by the fastened wallboard panels in a tongue and groove relationship.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
261 words
Wallboard fasteners useful for holding a first wallboard panel to a framing member at an end thereof and for joining to a second wallboard panel to be installed coplanar with and having an end thereof abutting the held end of the first panel so that parts of said fasteners, on installation of the second wallboard, contact the first panel, to which said fasteners are not joined, and prevent transverse movements of the second panel, which fasteners are each of a single piece of sheet metal having a substantially flat plate portion, a tongue portion extending from the plate portion and coplanar therewith, a pair of web portions, one on each side of the tongue portion and each extending at a right angle from said plate portion and an impaling flange portion extending from each web portion in the same direction essentially parallel to and overlying said plate portion and opposite to the direction in which the tongue extends so that the plate portion may contact the surface of the wallboard panel while the impaling flange portion is impaling said panel at an edge thereof, said fasteners including a walled depressed area in the plate and tongue portions with a longitudinal slot in the tongue portion, the depression being in a direction opposite to that in which the webs extend, and said fasteners being free of impaling portions extending in the direction of the tongue portion and being free of webs extending beyond the depression from the tongue and from the plate portions in the direction the depression extends from such portions.

Claim 3
Dependent Claim
101 words
Wallboard fasteners according to claim 1, in each of which the depressed area in the plate and tongue portions is of such a depth as to allow the head of a mounting screw passing through the slot in said depressed area to be below the surface of the tongue portion of the fastener and in which said depressed area has a substantially flat bottom and terminates short of the end of the tongue portion so as to facilitate insertion of fasteners impaled on a second wallboard panel behind a mounted first wallboard panel as the panels are assembled on a wall.
Claim 4
Dependent Claim
25 words
Wallboard fasteners according to claim 1 wherein sides of the web portions near sides of the tongue portion are spaced away from said tongue portion.
Claim 5
Dependent Claim
25 words
Wallboard fasteners according to claim 2 wherein sides of the web portions near sides of the tongue portion are spaced away from said tongue portion.
Claim 6
Dependent Claim
19 words
Wallboard fasteners according to claim 4 wherein in each fastener the slot therein extends into the plate portion thereof.
Claim 7
Dependent Claim
79 words
Wallboard fasteners according to claim 1 which are of steel, each of which comprises a substantially rectangular flat plate portion, a substantially rectangular tongue portion coplanar with the plate portion and extending longitudinally axially from it, a longitudinally axially located flat bottomed depressed area in both plate and tongue portions and a longitudinally axially located slot opening therethrough in the tongue portion, and in which, between each of the webs and the plate portion there is a clearance opening.
Claim 8
Dependent Claim
79 words
Wallboard fasteners according to claim 2 which are of steel, each of which comprises a substantially rectangular flat plate portion, a substantially rectangular tongue portion coplanar with the plate portion and extending longitudinally axially from it, a longitudinally axially located flat bottomed depressed area in both plate and tongue portions and a longitudinally axially located slot opening therethrough in the tongue portion, and in which, between each of the webs and the plate portion there is a clearance opening.
