Abstract
Abstract A taping gun or tool for dispensing tape for drywall or the like comprising a handle-like support means having a container mounted thereon adapted to receive a cement material therein. The container is provided with a first tape opening formed therein adjacent the juncture of the rearward and top walls thereof and has a second tape opening formed therein at the juncture of the front and top walls. A roll of tape is rotatably mounted on the support at the rearward end thereof and extends through the first tape opening and thence along the interior surfaces of the container rear wall, bottom wall, forward and thence outwardly through the second tape opening. A first roller is rotatably mounted on the forward end of the container and is adapted to receive the tape extending therearound to enable the roller to apply the tape having cement thereon to the drywall or the like. A tape cutter assembly is pivotally mounted on the forward end of the container and is movable from a tape cutting position to a non-cutting position. A spring is operatively connected to the tape cutter assembly for maintaining the assembly in its cutting position. An elongated flexible member is also secured to the tape cutter assembly to enable the operator to selectively maintain the tape cutter assembly in its non-cutting position. An elongated flat flexible member also extends through the interior of the container and is manually movable to permit pressure to be exerted on the tape towards the cement in the container.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
293 words
A tapping tool comprising, a support means having rearward and forward ends, a container mounted on said support means adapted to receive a cement material therein, said container having a rearward wall, a forward wall, spaced apart side walls, a bottom wall and a closable top wall, said container having a first tape opening formed therein between rearward wall and said top wall, said container having a second tape opening formed therein between said front wall and said top wall, means for supporting a roll of tape material on said support means adjacent the rearward end thereof so that said tape material may pass into said container through said first opening, thence adjacent said rearward wall, thence adjacent said bottom wall, thence adjacent said forward wall, thence outwardly through said second opening, said cement material in said container being normally positioned above said tape material so that a layer of cement material is placed on said tape material as said tape material is pulled through said container, a first roller means operatively rotatably mounted at the forward end of said container adapted to have the tape material with cement thereon pass at least partially therearound and onto a wall surface as the tape material is applied thereto, and a tape cutter assembly pivotally mounted at the forward end of said container adjacent said first roller, said tape cutter assembly being movable between a first non-cutting position to a second cutting position, said tape cutter assembly having a blade mounted thereon, means normally yieldably urging said tape cutter assembly to its said cutting position, and means on said tape cutter assembly for selectively maintaining said blade out of engagement with the tape material when said tape material is being applied to the wall surface.
Claim 2
Dependent Claim
293 words
A tapping tool comprising, a support means having rearward and forward ends, a container mounted on said support means adapted to receive a cement material therein, said container having a rearward wall, a forward wall, spaced apart side walls, a bottom wall and a closable top wall, said container having a first tape opening formed therein between rearward wall and said top wall, said container having a second tape opening formed therein between said front wall and said top wall, means for supporting a roll of tape material on said support means adjacent the rearward end thereof so that said tape material may pass into said container through said first opening, thence adjacent said rearward wall, thence adjacent said bottom wall, thence adjacent said forward wall, thence outwardly through said second opening, said cement material in said container being normally positioned above said tape material so that a layer of cement material is placed on said tape material as said tape material is pulled through said container, a first roller means operatively rotatably mounted at the forward end of said container adapted to have the tape material with cement thereon pass at least partially therearound and onto a wall surface as the tape material is applied thereto, and a tape cutter assembly pivotally mounted at the forward end of said container adjacent said first roller, said tape cutter assembly being movable between a first non-cutting position to a second cutting position, said tape cutter assembly having a blade mounted thereon, means normally yieldably urging said tape cutter assembly to its said cutting position, and means on said tape cutter assembly for selectively maintaining said blade out of engagement with the tape material when said tape material is being applied to the wall surface.
Claim 3
Dependent Claim
49 words
The tool of claim 1 wherein said means on said tape cutter assembly comprises a flexible member secured at one end thereof to said tape cutter assembly and extending therefrom, a slide member movably mounted on said container and having the other end of said flexible member secured thereto.
Claim 4
Dependent Claim
23 words
The tool of claim 2 wherein said means on said tape cutter assembly also comprises a second roller rotatably mounted on said blade.
Claim 5
Dependent Claim
16 words
The tool of claim 3 wherein said second roller also comprises a tape material creasing member.
Claim 6
Dependent Claim
19 words
The tool of claim 3 wherein a third roller is mounted on said blade opposite to said second roller.
Claim 7
Dependent Claim
45 words
The tool of claim 1 wherein an auxiliary tape material cutter blade is slidably mounted on said top wall and has a cutting edge positioned adjacent said second tape opening, said auxiliary cutting blade being slidably movable from a stored position to a cutting position.
Claim 8
Dependent Claim
23 words
The tool of claim 1 wherein said first roller means comprises a drum member having tape gripping means provided on the periphery thereof.
Claim 9
Dependent Claim
20 words
The tool of claim 1 wherein said roller means and said tape cutter assembly have common rotational and pivotal axes.
Claim 10
Dependent Claim
24 words
The tool of claim 1 wherein said means normally yieldably urging said tape cutting assembly to its said cutting position comprises a spring means.
Claim 11
Dependent Claim
143 words
The tool of claim 1 wherein an elongated flat flexible member is secured at one end to said container adjacent said second opening and extends therefrom adjacent said forward wall, thence adjacent said bottom wall, thence adjacent said rearward wall and thence outwardly from said container, thence adjacent the exterior surface of said rearward wall, thence adjacent the exterior surface of said bottom wall, said tape material in said container normally being positioned between said flat flexible member and said cement material, and slide connection means secured to the other end of said flat flexible member and being operatively slidably mounted on said container whereby slidable movement of said slide connection means in a forwardly direction relative to said container will cause said flat flexible member to urge said tape material in said container into engagement with the cement material in said container.
Claim 12
Dependent Claim
22 words
The tool of claim 10 wherein said flat flexible member has a width substantially equal to said tape material and said container.
