Abstract
An improvement in a pipe bending device to predetermine the offset distance without removing the pipe from the bender. An adhesive tape with incremental markings thereon is applied on the handle of the pipe bender in a manner so that a sight line intersects the handle at the incremental mark indicating the amount of offset desired after the first bend is made.

A method for adapting an existing manual pipe bender, of the type having a single forming head and a handle, for performing accurately and readily offset bends, which comprises:
- 1. providing an adhesive tape having a scale thereon of incremental markings such that:
- a. the first increment, marked 1, is actually one-fourth of an inch from one end,
- b. the second increment, marked 2, is actually one and one-half inches from said one end,
- c. the third increment, marked 3, is approximately 3 inches from said one end,
- d. the fourth and subsequent increments are located at 1 inch intervals from the third increment,
- 2. applying said tape longitudinally to the handle of the bender such that the said one end of the tape abuts the forming head.
A method for utilizing an existing manual pipe bender of the type having a forming head and a handle to perform pipe offset bending operations, which comprises the following steps:
- 1. providing an adhesive tape with incremental scale markings on the non-adhesive face thereof,
- 2. applying said tape longitudinally to the handle of the bender such that the end of the tape with the low end of the scale is uppermost and adjacent to the forming head,
- 3. inserting a length of pipe in the forming head of the bender and making a first bend therein where desired,
- 4. rotating the pipe to a position in which the projection of the bent section of pipe intersects the handle perpendicularly,
- 5sliding the pipe to a position such that, when sighting along the bent section of pipe, the sight line intersects the scale markings on the tape at the desired offset distance, and
- 6. bending the pipe a second time while pipe and bender are fixed in position attained in step (5.)
In a manual pipe bender of the type having a single forming head and a handle, extending substantially radially therefrom, the improvement which comprises applying to the said handle an adhesive tape having on its outer face a scale of incremental markings such that:
- a. the first increment, marked 1, is actually one-fourth of an inch from one end of the tape,
- b. the second increment, marked 2, is actually one and one-half inches from the forming head,
- c. a third increment, marked 3 is approximately three inches from the forming head, and
- d. the fourth and subsequent increments are located at 1 inch intervals from the third increment.
An adhesive tape for use in modifying an existing manual pipe bender to enable it to perform readily and quickly pipe offset bending operations, which tape comprises a self-adhering adhesive on one face thereof and a scale on the opposite face thereof, said scale having incremental markings such that:
- a. the first incremental mark, marked 1, is actually one-fourth of an inch from one end of the tape,
- b. the second incremental mark, marked 2, is actually one and one-half inches from said one end of the tape,
- c. the third incremental mark, marked 3, is substantially three inches from said one end of the tape, and
- d. the fourth and subsequent incremental marks, marked 4, 5, etc., are located at 1-inch intervals from the third incremental mark.
