摘要： An L shaped versatile, combination construction square for a carpenter having measured marks for all common framing combinations about its six sides. A series of template openings, as well as two adjustable base arms able to set angles for setting plumb, lock into a position to cut rafter tails and birds mouths as well as stair treads and risers. It has a precise scale that accommodates a traditional carpenter's rectangular 3/16 inch wide pencil lead that allows for ⅛ inch increments that can be transferred the length of a board using the adjustable arms. It also functions as a framing square and a laser angle finder.

摘要： A roof square for marking rafters comprising a right angle triangular body with a marking blade pivotally mounted adjacent the right angle. Either side of the square adjacent the right angle is held against the stock to be marked, and the blade used to mark either a plumb cut or a foot cut. The blade retracts to allow marks to be made at a measured depth. The tool can also be used as a conventional square to make 90 and 45 degree marks.

摘要： A device that teaches the relationship between a right triangle, the length of its hypotenuse, the length of its two sides and the trigonometric functions. The device includes a horizontal and vertical ruler attached by a sliding attachment bracket. A circular plate showing 360 degrees (θ) is attached to the horizontal ruler along with a pivoting ruler that can rotate 360 degrees. By sliding the vertical ruler along the horizontal ruler and revolving the pivoting ruler, the height of the vertical ruler (Y) where it intersects the pivoting ruler, the length of the horizontal ruler (X) where it intersects the vertical ruler, and the length of the of the pivoting ruler (R) where it intersects the vertical ruler can be measured. The trigonometric functions can then be calculated and plotted by their relationship with the measured values of X, Y, R and θ.

摘要： An apparatus for verifying placement of a rear view mirror mounting button on a motor vehicle windshield includes a first member pivotally attached to a second member for rotation about an axis. The first member includes a portion adapted to align the first member substantially perpendicular to an edge of the windshield. The second member is adapted to engage the mounting button such that the second member is aligned with a longitudinal axis of the mounting button. The apparatus further includes cooperating indicia carried by the first and second members for determining the accuracy of alignment between the first and second members.

摘要： The invention relates to a hand tool which is capable of functioning as a framing square, a roofing framing square or rafter square, a plumb bob, a level, and a gauge or scribe for straight lines, arcs, or circles. The hand tool preferably includes a body, a plate and a releasable locking member. The body includes first and second ends, first and second sides, a top surface and a bottom surface. The hand tool may include a light source disposed at the first end of the body, a horizontal level vial intermediate the first and second sides, a vertical level vial intermediate the first and second sides, and a straight sliding slot intermediate the first and second sides such that the straight sliding slot transverses the body from the first side to the second side providing an aperture. The plate is pivotally attached to the body by a pivot member. The pivot member is disposed in the straight sliding slot thereby allowing the pivot member to be slidably captured therein. The plate includes an arcuate sliding slot. The releasibly locking member has a locked position and an unlocked position and is disposed in the arcuate sliding slot and the straight sliding slot. The releasable locking member allows variable orientation of the plate with respect to the body in its unlocked position such that the plate is permitted to rotate about the pivot member and slide linearly along the straight sliding slot.
