Pipe splitter

The pipe splitter comprising:

• an elongated frame having a first end and a second end;
• said elongate frame further including a first side and a second side;
• a first roller and a second roller rotatably positioned proximate said first end and said second end of said elongated frame, respectively, to rotatably support said elongated frame along a first longitudinal path of a pipe to be split when positioned into the bore of the pipe to be split;
• a first coupling means securably positioned at said first end of said elongated frame to enable said elongated frame to be pulled along a longitudinal dimension of the pipe;
• a cutting wheel positioned between said first end and said second end of said elongated frame such that said first and second rollers supportingly engage an internal surface of the pipe to be split and said cutting wheel cuttably engages the thickness of the pipe wall along a second longitudinal path of the pipe to be split thereby splitting the pipe along said second longitudinal path thereof which is opposite said first longitudinal path traveled by said first and second rollers within the bore of the pipe to be split;
• and
• each said roller including an arced rim such that said arced rim of each said roller coincides with an arc of the inner periphery of the interior lengthwise cylindrical cavity of the pipe to be split.

A pipe splitter comprising:

• an elongated frame having a first end and a second end;
• said elongate frame further including a first side and a second side;
• a first aperture and a second aperture formed in said elongate frame proximate said first and said second ends of said elongate frame, respectively;
• a first roller and a second roller rotatably positioned in said first and said second apertures, respectively, to rotatably support said elongated frame when positioned into the bore of the pipe to be split and being moved along a first longitudinal path of the pipe to be split;
• a first coupling means securably positioned at said first end of said elongated frame to enable said elongated frame to be pulled along a longitudinal dimension of the pipe;
• a second coupling means positioned at said second end of said elongated frame to enable a coupling of a replacement pipe such that said replacement pipe follows said elongated frame being pulled along said longitudinal dimension of the pipe;
• a third aperture formed in said elongate frame between said first aperture and said second aperture of said elongate frame;
• a cutting wheel rotatably positioned in said third aperture such that said first and second rollers supportingly engage the internal surface of the pipe to be split and said cutting wheel cuttably engages the thickness of the pipe wall along a second longitudinal path of the pipe to be split thereby splitting the pipe along said second longitudinal path thereof which is opposite said first longitudinal path traveled by said first and second rollers within the bore of the pipe to be split;
• said cutting wheel having a circular dimension greater than the bore of the pipe and said first and said second rollers are dimensioned and positioned on said elongated frame such that said cutting wheel engages the pipe to be split and forms a single longitudinal split along the second longitudinal path of the pipe;
• each said side of said elongated frame further including a first opening and a second opening formed therein and extending through said first side of said elongate frame and said second side of said elongate frame;
• a first axle and a second axle being supportably received by said first and said second opening in said elongate frame, respectively, for rotatably supporting said first and said second roller wheels received in said first and said second apertures, respectively;
• each said first and said second roller wheels further include a first and a second axle bore for receiving said first axle and said second axle, respectively;
• each said side of said elongated frame further includes a third opening formed therein and extending through said first side of said elongate frame and said second side of said elongate frame;
• a third axle being supportably received by said third opening in said elongate frame for rotatably supporting said cutting wheel received in said third aperture;
• said cutting wheel further includes an axle bore for receiving said third axle;
• a first side wheel and a second side wheel positioned at said first side and said second side of said elongated frame, respectively, such that said first and said second side wheels engage the internal surface of the pipe to be split in a plane perpendicular to a plane of said first and said second rollers to prevent the inward collapsing of the pipe to be split thereby enhancing in use the cutting engagement of a pipe coupling without collapsing the pipe coupling during the passage of said cutting wheel through the thickness of the pipe to be split;
• said elongate frame further includes a fourth and a fifth opening formed therein and extending through said elongate frame;
• a fourth and a fifth axle being supportably received by said fourth and said fifth opening in said elongate frame, respectively, for rotatably supporting said first side wheel and said second side wheel;
• said first side wheel and said second side wheel further include an axle bore for receiving said fourth and said fifth axle;
• and
• a means for preventing axle rotation of said first, second, third, fourth and fifth axles relative to said elongated frame thereby enabling said first roller, said second roller, said cutting wheel and said first and said second side wheels to rotate relative to said first axle, said second axle, said third axle, said fourth axle and said fifth axle, respectively.
