Claims (1)

[Claims for Utility Model Registration] (1) A. An integrally formed product having the outer shape of a right triangle with first and second sides intersecting at right angles and a third side extending between their opposing ends. a pivot hole spaced along the second side from the intersection point and inwardly from the second side; a convex arcuate groove formed by a radius spaced from a right-angled intersection of the parts and having as its origin the pivot hole, the arcuate groove being closer to the first side than the pivot hole; the body also having an arcuate side thereof spaced apart from the arcuate groove and a pair of intersecting straight sides adjacent to the pivot hole; an arcuate-sided hole between the groove and the arcuate-sided hole, the arcuate side being formed by a radius having as its origin the pivot hole; a first scale marking angular graduations spaced along said arcuate side of a shaped-sided hole; markings spaced along a side of said arcuate groove adjacent said arcuate side; a second scale with markings and a third scale with markings spaced apart along the other side of said arcuate groove, said second and third scales having markings with markings; Corresponding to the unit rise per unit length in the direction of the hanging tartar, the third scale is graduated for use with ordinary tartar jacks,
and a second scale calibrated for use with hipped and valley jacks; a protractor arm comprising a pair of elongate arm elements overlapping in an arcuate groove; C a pivot device engaged in said arm elements and extending through said pivot hole; D a pivot device installed in said arm element and sliding in said arcuate groove. A sliding locking device is possible, the locking device being in clamping engagement with the arm element against opposite sides of the body and capable of being manually removed from the clamping engagement, the locking device being capable of being manually removed from the clamping engagement, enabling movement of one of the three scales to a selected mark, whereby the longitudinal edge of the protractor arm adjacent to the first side of the body is placed against the upper edge of the rafter; cut, and the first side of the body provides a score line to be cut for a bottom cut, and the other longitudinal edge of the protractor arm is placed in a rafter thereby to be cut. and the second side of the body provides a score line to be cut for a hip cut, and thereby the protractor arm is used to cut the edge defined by the first side. A ruler for use in the design of barrel cuts, including a sliding lock device adapted to define the angular cut. (2) Utility model registration The ruler according to claim 1, wherein the main body includes a fourth scale having unit length graduations spaced apart along the second side. A ruler used for designing. (3) Utility Model Registration The ruler according to claim 1, wherein the tightening device includes a threaded recess in one of the arm elements and a threaded member attached to a hole in the other arm element. Ruler used for cutting design. (4) Utility model registration In the ruler according to claim 3, the hole in the other arm element has the shape of a keyhole and is used for the design of a barrel cut to lock the threaded member therein. ruler. (5) The ruler according to claim 4, wherein the threaded fastener is a barrel having a handle having an enlarged knurled head and a threaded portion engaged in the threaded recess. A ruler used for cutting design. (6) Utility Model Registration In the ruler according to claim 1, each of the arm elements has a thickness at least equal to the thickness of the main body member, and has a thickness for installation against the edge of the rafter. A ruler used in the design of stubble cuts that provides a stable impact surface. (7) In the ruler according to claim 1 of the utility model registration claim, the zero graduation for each of the first, second and third scales is parallel to the first side. When the ruler used in designing the cooper cut is aligned with the other longitudinal edge of the protractor arm. (8) The ruler according to claim 1, wherein the third side includes a scale along at least a portion of its length that includes an angular graduation that cooperates with the graduation of the first scale. A ruler used in the design of barrel cutting with a scale of five. (9) In the ruler according to claim 8 of the utility model registration, the first scale extends around an arc smaller than 90°, and the fifth scale is different from the first scale. A ruler used in the design of barrel cuts that includes marks extending 90° from the end mark.
