Abstract: Position and angle are measured by a linear device having an elongate frame comprising a pair of parallel arms joined by a cross-arm, each of the arms terminating with an adjustable foot so that the device may be leveled, thereby establishing a level reference platform from which position and direction may be determined. A support bracket is adapted for rigid engagement with the elongate frame and is linearly positionable on it. A laser beam source is removably engagable with the support bracket for positioning a laser beam in a selected and known direction. The feet are spaced for clamping the T-bar sections of a dropped ceiling so as to enable the placement of further T-bars, roof joists and other structural members at selected angles. The arms provide parallel, spaced apart grooves for mounting the apparatus onto the T-bars.

Abstract: In a coordinate measurement device with a base frame, a measurement table supported at the latter for holding an object to be measured, a sensing device for sensing the surface of this object, and with a positioning device for moving the sensing device in three spatial axes over the measurement table, which positioning device is mounted at the base frame and carries the sensing device, the positioning device has a first slide which is guided at the base frame in a first direction and which is movable on one side of the measurement table toward and away from the latter and on which a second slide is movable in a second direction vertical to the first direction, this second slide being provided at its end area remote of the measurement table (considered in its movement direction) with a supporting portion which projects lateral to the measurement table and at which there is arranged a stirrup arm which projects over the measurement table in a direction vertical to a principal work plane of the measurement table

Abstract: An archery bow sight is provided in which the sight mount includes a horizontal adjustment mechanism to adjust the horizontal position of the sight relative to the bow, in addition to the vertical position of the sight. Indicia are provided on the horizontal adjustment mechanism to determine the amount of adjustment that has been made to the sight.

Abstract: A measuring tool for measuring in two directions orientated perpendicular to each other such that obstructions may be accurately measured. The measuring tool includes an elongated member having a first end, a second end, a top side, a bottom side, a front side, and a back side. The front side has an elongated slot therein. The slot extends between the first and second ends. The bottom side has a channel therein extending between the first and second ends. The front side has length measuring indicia thereon. The length measuring indicia extends between the first and second ends. Each of a pair of arms is movably positioned on the elongated member and each extends below the bottom side of the elongated member. Each of the arms are movably coupled to the slot and the channel. The arms each have measuring indicia thereon.

Abstract: The present invention includes a gauging tool for attachment to a fastener gun which dispenses fasteners. The gauging tool includes a positioning shoulder that is placed against the shoulder of siding that is to be secured to the wall of a building. The siding includes an attaching lip through which fasteners are driven for fastening the siding to the wall. The gauging tool of the present invention automatically positions the fastener a selected distance from the shoulder of the siding and automatically drives the fastener a selected depth into the wall.
