Claim 1
Independent Claim
218 words
A repair patch for closing a hole in a wallboard on which an overlay of plaster or similar material is to be applied comprising a first panel having a front and a rear surface, said first panel being adapted to be folded together transversely across the front surface for insertion through said hole and thereafter unfolded to fit flush against the concealed surface of the wallboard to close said hole, a second panel secured to the rear surface of said first panel so as to urge said first panel to its unfolded position, a plate secured between said panels having a threaded aperture, said panels having apertures in registry with said threaded aperture, a screw of a selected length threadedly connected to said threaded aperture and adapted to be turned to advance the screw against an abutment to the rear of said wallboard for securing said first panel in said flush position, and a string attached to the front surface of said first panel for holding the latter in place when said screw is being turned, the stem of said screw being threaded its full length so that the head of the screw can be located against the first panel and the applied overlay material can then conceal the screwhead when the repair patch is mounted in place.

Claim 3
Dependent Claim
15 words
A repair patch as is defined in claim 1, wherein said panels are corrugated cardboard.
Claim 4
Dependent Claim
22 words
A repair pitch as is defined in claim 2, wherein the corrugations of said first panel are parallel to the transverse fold.
Claim 5
Dependent Claim
22 words
A repair patch as is defined in claim 3, wherein the corrugations of said second panel are perpendicular to the transverse fold.
Claim 6
Dependent Claim
205 words
A repair patch for closing a hole in a wallboard on which an overlay of plaster or similar material is to be applied comprising a first corrugated cardboard panel having a front and a rear surface, said first panel being adapted to be folded together transversely across the front surface for insertion through said hole and thereafter unfolded to fit flush against the concealed surface of the wallboard to close said hole, said first panel having two parallel creases in its front surface, said creases being parallel to the corrugations of said first panel to facilitate making said transverse fold, a second corrugated cardboard panel secured to the rear surface of said first panel, the corrugations of said second panel being perpendicular to the transverse fold, a plate secured between said panels having a threaded aperture, said panels having apertures in registry with said threaded aperture, a screw threadedly connected to said threaded aperture and adapted to be turned to advance the screw against an abutment to the rear of said wallboard for securing said first panel in said flush position, and a string attached to the front surface of said first panel for holding the latter in place when said screw is being turned.
Claim 7
Dependent Claim
205 words
A repair patch for closing a hole in a wallboard on which an overlay of plaster or similar material is to be applied comprising a first corrugated cardboard panel having a front and a rear surface, said first panel being adapted to be folded together transversely across the front surface for insertion through said hole and thereafter unfolded to fit flush against the concealed surface of the wallboard to close said hole, said first panel having two parallel creases in its front surface, said creases being parallel to the corrugations of said first panel to facilitate making said transverse fold, a second corrugated cardboard panel secured to the rear surface of said first panel, the corrugations of said second panel being perpendicular to the transverse fold, a plate secured between said panels having a threaded aperture, said panels having apertures in registry with said threaded aperture, a screw threadedly connected to said threaded aperture and adapted to be turned to advance the screw against an abutment to the rear of said wallboard for securing said first panel in said flush position, and a string attached to the front surface of said first panel for holding the latter in place when said screw is being turned.
Claim 8
Dependent Claim

A repair patch as is defined in claim 5, wherein said creases are on opposite sides of the aperture in the first panel.
Claim 11
Dependent Claim
201 words
A repair patch for closing hole in a wallboard on which an overlay of plaster or similar material is to be applied comprising a panel means having a greater area than said hole and formed to be constricted for passage through said hold and to be returned to its original shape for fitting against the concealed surface of the wallboard to close said hole, and a thrust member connected to said panel means and extensible in a direction rearwardly of said panel means for engagement with an abutment located a preestablished distance rearwardly of the wallboard to exert a forward thrust against said panel means for holding the latter against the concealed surface of said wallboard, said panel means including two panels and said plate having a apertures in registry, and said thrust member being a screw which extends through said registered apertures and is threadedly connected to said resilient plate, the stem of the screw having a length approximately equal to said preestablished distance and being threaded so that the head of the screw can be seated against the panel means when the repair patch is installed in place, thereby allowing the head to be concealed in the overlay material.
