Abstract
Abstract A multi-functional tool arranged to allow rapid marking of perpendicular and angular lines on material surfaces is disclosed. One or more extendable stops are provided in the body of the tool to rapidly fix the angular orientation of a marking edge. Optionally, associated measuring devices such as a level, tape measure, and plumb bob, may be included to facilitate the location and orientation of the position to be marked.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
A multi-functional square and angle marking tool comprising in combination: a. a handle having at least one flat surface; b. a body portion thinner than said handle having two parallel edges and two parallel sides, said body portion attached to said handle substantially in the center of said flat surface such that said parallel sides and edges extend perpendicularly from said surface; c. a stop extendably mounted through said parallel sides of said body portion a selected distance from said flat surface; d. means for securing said stop in a retracted position whereby said stop is positioned not to extend beyond either of said sides; and e. means for securing said stop in an extended position whereby said stop is positioned to extend beyond either of said sides.
Claim 2
Dependent Claim
128 words
A multi-functional square and angle marking tool comprising in combination: a. a handle having at least one flat surface; b. a body portion thinner than said handle having two parallel edges and two parallel sides, said body portion attached to said handle substantially in the center of said flat surface such that said parallel sides and edges extend perpendicularly from said surface; c. a stop extendably mounted through said parallel sides of said body portion a selected distance from said flat surface; d. means for securing said stop in a retracted position whereby said stop is positioned not to extend beyond either of said sides; and e. means for securing said stop in an extended position whereby said stop is positioned to extend beyond either of said sides.
Claim 3
Dependent Claim
23 words
The apparatus of claim 1 wherein said stop comprises a plate pivotally mounted in said body, said plate having a V-shaped forward edge.
Claim 4
Dependent Claim

Claim 7
Dependent Claim
52 words
The apparatus of claim 1 wherein the surface of said handle opposite said flat surface is pyramidal in shape, and said body has a hole passing through said body surfaces opposite the apex of said pyramidal surface whereby said tool may form a blumb bob by tieing a string through said hole.
Claim 8
Dependent Claim
18 words
The apparatus of claim 1 further including scale indicia marked along at least one of said body edges.
