Abstract
A pipe peeler for removing a uniform layer of material from the outer surface of a polyethylene pipe is provided. The device comprises a cuboid body, a blade with housing for retracting the blade, a chain attached to one end of the cuboid body, a threaded hook for attaching the other end of the chain to the cuboid body and tightening the chain around a pipe, and a push knob for rotating the device around the pipe in order to peel the pipe. The two points on the chain attached to the body are different distances from the end of the pipe when the chain is tightened around the pipe, thereby creating a spiral track on the pipe that the blade will follow when the device is pushed around the pipe, thereby creating a uniform spiral peel.
Claims11
A device for peeling a pipe, comprising:
- (A) a body;
- (B) a blade attached to said body;
- (C) a chain;
- (D) a first fastener, wherein said first fastener is operable to attach a first point on said chain to said body;
- (E) a chain tightener, wherein
- (1) said chain tightener includes a second fastener, and wherein said second fastener is operable to attach a second point on said chain to said body, and
- (2) wherein said chain tightener is operable to reduce any a distance between said second point and said body when said second point is attached to said second fastener,
- wherein said chain between said first and second points defines a helix when said first and second points are attached to said first and second fasteners respectively and when every point on said chain between said first and second points is extended a maximum average distance from all other points on said chain that are between said first and second points.
A device for peeling a pipe, comprising:
- (A) a body;
- (B) a blade attached to said body;
- (C) a chain;
- (D) a first fastener, wherein said first fastener is operable to attach a first point on said chain to said body;
- (E) a chain tightener, wherein
- (1) said chain tightener includes a second fastener, and wherein said second fastener is operable to attach a second point on said chain to said body, and
- (2) wherein said chain tightener is operable to reduce any a distance between said second point and said body when said second point is attached to said second fastener,
- wherein said chain between said first and second points defines a helix when said first and second points are attached to said first and second fasteners respectively and when said chain between said first and second portions is positioned as an arc portion of a circle.
A device for peeling a pipe, comprising:
- (A) a body;
- (B) a blade attached to said body;
- (C) a chain;
- (D) a first fastener, wherein said first fastener is operable to attach a first point on said chain to said body;
- (E) a chain tightener, wherein
- (1) said chain tightener includes a second fastener, and wherein said second fastener is operable to attach a second point on said chain to said body, and
- (2) wherein said chain tightener is operable to reduce any a distance between said second point and said body when said second point is attached to said second fastener,
- wherein said first and second fastener are located on opposing sides of said body, and wherein said first and second fasteners are offset from one another, such that said chain defines a helix when said first and second points are attached to said first and second fasteners respectively and when said chain is wrapped and tightened around the pipe.
