## Title
Pipe joint scribe kit

## Abstract

A pipe joint scribe kit for welding pipes together at intersections, which may or may not be perpendicular, including a plurality of single-piece scriber bodies, each body having a pair of parallelepiped arms, with incremental graduations marked thereon, disposed at a fixed angle with respect to each other with at least one angle portion disposed between the arms.

## Background
BACKGROUND OF THE INVENTION
Various types of pipe scribers are known in the prior art. These previous pipe scribers are often limited in the type of connection that can be scribed, perhaps only a “T” branch connection for example. In addition, many of the previous pipe scribers require multiple adjustments prior to use. Some of the previous pipe scribers are formed of multiple elements, including coil springs and gears, that can break. The present device addresses the foregoing issues by providing a pipe joint scribe kit for welding pipes together at intersections, which may or may not be perpendicular, the kit providing a plurality of single-piece scriber bodies, each body having a pair of parallelepiped arms, with incremental graduations marked thereon, disposed at a fixed angle with respect to each other with at least one angle portion disposed between the arms.
FIELD OF THE INVENTION
The present invention relates to pipe scribers, and more particularly, to a pipe joint scribe kit which provides a plurality of single-piece scriber bodies, each body having a pair of parallelepiped arms, with incremental graduations marked thereon, disposed at a fixed angle with respect to each other with at least one angle portion disposed between the arms.
SUMMARY OF THE INVENTION
The general purpose of the present pipe joint scribe kit, described subsequently in greater detail, is to provide a pipe joint scribe kit which has many novel features that result in a pipe joint scribe kit which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.
To accomplish this, the present pipe joint scribe kit, designed for welding a pair of pipes together at intersections, which may or may not be perpendicular is illustrated. The instant pipe joint scribe kit includes a single-piece arcuate first scriber body for welding pipes together at a 90-degree angle and a single-piece arcuate second scriber body for welding pipes together at a 45-degree angle. Each of the first and second scriber bodies has a parallelepiped first arm, a parallelepiped second arm, and a first angle portion disposed therebetween.
Each of the first and second arms has an inside edge and an outside edge. A concave interior edge of the first angle portion is continuously disposed between the inside edge of the first arm and the inside edge of the second arm. A convex exterior edge of the first angle portion is continuously disposed between the outside edge of the first arm and the outside edge of the second arm in a position opposite the interior edge.
The first angle portion of the first scriber body has a greater angle than the first angle portion of the second scriber body. The first arm and the second arm of the first scriber body are perpendicular to each other. The first arm and the second arm of the second scriber body are positioned at a 45-degree angle relative to each other. The first arm has a length at least twice as long as a length of the second arm in each of the first scriber body and the second scriber body. A plurality of incremental graduations is disposed on each of the inside and outside edges of the first and second arms.
The kit also provides a single-piece arcuate third scriber body for welding a pair of pipes in a gooseneck fitting together. The third scriber body has a parallelepiped first member, a parallelepiped second member, a first angle section disposed proximal the second member, and a second angle section. The second angle section is continuously disposed between the first angle section and the first member. Each of the first and second members has an inner edge and an outer edge. The first and second angle sections are continuously disposed between the first and second members. The second angle section has an internal edge and a straight external edge.
A U-shaped interior side of the first angle section is disposed between the inner edge of the second member and the internal edge of the second angle section. A convex exterior side of the first angle section is disposed between the outer edge of the second member and the external edge of the second angle section in a position opposite the interior side. The external edge of the second angle section is perpendicular to the outer edge of the second member. The configuration of the first angle section accommodates a gooseneck pipe fitting.
A plurality of incremental graduations is disposed on each of the inner and outer edges of the first and second members. In the third scriber body, the second member has a length at least three-fourths a length of the first member.
Thus has been broadly outlined the more important features of the present pipe joint scribe kit so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.

The instant pipe joint scribe kit includes a single-piece arcuate first scriber body 20 for welding pipes together at a 90-degree angle and a single-piece arcuate second scriber body 22 for welding pipes together at a 45-degree angle. Each of the first and second scriber bodies 20, 22 has a parallelepiped first arm 24, a parallelepiped second arm 26, and a first angle portion 28 disposed therebetween.
Each of the first and second arms 24, 26 has an inside edge 30 and an outside edge 32. A concave interior edge 34 of the first angle portion 28 is continuously disposed between the inside edge 30 of the first arm 24 and the inside edge 30 of the second arm 26. A convex exterior edge 36 of the first angle portion 28 is continuously disposed between the outside edge 32 of the first arm 24 and the outside edge 32 of the second arm 26 in a position opposite the interior edge 34.
The first angle portion 28 of the first scriber body 20 has a greater angle than the first angle portion 28 of the second scriber body 20. The first arm 24 and the second arm 26 of the first scriber body 20 are perpendicular to each other. The first arm 24 and the second arm 26 of the second scriber body 22 are positioned at a 45-degree angle relative to each other. The first arm 24 has a length at least twice as long as a length of the second arm 26 in each of the first scriber body 20 and the second scriber body 22. A plurality of incremental graduations 40 is disposed on each of the inside and outside edges 30, 32 of the first and second arms 24, 26. A plurality of indicia 42 corresponding to the incremental graduations 40 is provided. The plurality of indicia 42 on the inside edge 30 of each of the first and second arms 24, 26 is in a mirror image arrangement relative the plurality of indicia 42 on the outside edge 32 of each of the first and second arms 24, 26.
The kit also provides a single-piece arcuate third scriber body 50 for welding a pair of pipes including a gooseneck fitting together. The third scriber body 50 has a parallelepiped first member 52, a parallelepiped second member 54, a first angle section 56 disposed proximal the second member 54, and a second angle section 58. The second angle section 58 is continuously disposed between the first angle section 56 and the first member 52. Each of the first and second members 52, 54 has an inner edge 60 and an outer edge 62.
