Abstract
A saw angle gage is a square or rectangular shaped platform with two (2) electrical contacts attached to one of the four sides of the platform. A battery and a light are mounted to the platform and wired together with the two (2) electrical contacts forming an isolated electrical circuit that is open between the two (2) electrical contacts. When both of the electrical contacts touch a current conducting object, the light will illuminate. When both electrical contacts touch a current conducting object and the full length of one of the adjacent sides of the platform touches a different object, the light will illuminate, indicating a right-angle relationship between the objects. When both electrical contacts touch a current conducting object and the full length of the opposite side of the platform touches a different object, the light will illuminate, indicating a parallel relationship between the objects.
Claims
1. A saw angle gage comprised of: a platform a battery a light two (2) electrical contacts electrical wiring wherein each of the four sides of the platform are at a right angle with respect to each adjacent side of the platform; the battery and light are affixed to the top of or embedded within the platform and the two (2) electrical contacts are spaced apart and attached to one side of the platform. A straight line drawn between the tip of each of the two (2) electrical contacts is at a right angle to each of the adjacent sides of the platform and is parallel with the opposite side of the platform. The electrical components and wiring form an isolated electrical circuit that is open between the two (2) electrical contacts; the purpose of which is to only illuminate the light when both of the contacts are touching a current conducting object.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE PRESENT INVENTION
[0018] The saw angle gage, as depicted in FIG. 1 and FIG. 2 consists of a four-sided platform 1, battery 2, electrical wires 3,5 and 8, light 4 and electrical contacts 6 and 7. The battery 2 and light 4 are attached to or embedded in the top surface of platform 1. The electrical contacts 6 and 7 are attached to side a of platform 1. Wire 3 connects battery 2 to the light 4. Wire 5 connects the light 4 to electrical contact 6. Wire 8 connects electrical contact 7 to battery 2.
[0019] A line drawn between the tip of electrical contact 6 and the tip of electrical contact 7 forms a right angle with respect to side b and side d of platform 1. A line drawn between the tip of electrical contact 6 and the tip of electrical contact 7 is parallel with side c of platform 1.
[0020] In FIG. 3 when using the saw angle gage with a chop or miter saw, side b of platform 1 of the saw angle gage is held against fixed fence 9 and only electrical contact 7 touches circular cutting blade 10. Light 4 will not illuminate, indicating fixed fence 9 and circular cutting blade 10 are not at a right angle with respect to each other.
[0021] In FIG. 4 when using the saw angle gage with a chop or miter saw, side b of platform 1 of the saw angle gage is held against fixed fence 9 and both electrical contacts 6 and 7 touch circular cutting blade 10. Light 4 will illuminate, indicating fixed fence 9 and circular cutting blade 10 are at a right angle with respect to each other.
[0022] In FIG. 5 when using the saw angle gage with a wood jointer, side b of platform 1 of the saw angle gage is held against fixed baseplate 11 and only electrical contact 7 touches adjustable fence 12. Light 4 will not illuminate, indicating fixed baseplate 11 and adjustable fence 12 are not at a right angle with respect to each other.
[0023] In FIG. 6 when using the saw angle gage with a wood jointer, side b of platform 1 of the saw angle gage is held against fixed baseplate 11 and both electrical contacts 6 and 7 touch adjustable fence 12. Light 4 will illuminate, indicating fixed baseplate 11 and adjustable fence 12 are at a right angle with respect to each other.
[0024] In FIG. 7 when using the saw angle gage with a table saw, side c of platform 1 of the saw angle gage is held against fixed circular cutting blade 10 and only electrical contact 7 touches adjustable fence 12. Light 4 will not illuminate, indicating fixed cutting blade 10 and adjustable fence 12 are not at a right angle with respect to each other.
[0025] In FIG. 8 when using the saw angle gage with a table saw, when side c of platform 1 of the saw angle gage is held against fixed circular cutting blade 10 and both electrical contacts 6 and 7 touch adjustable fence 12, light 4 will illuminate, indicating fixed circular cutting blade 10 and adjustable fence 12 are at a right angle with respect to each other.
