A device is provided for locating the center position of an object directly, without the need of measurement or mental computation. The device comprises a generally flat elongated frame having a center point marker and distance scales. Two pins are journaled in the frame, and a cord is disposed around the pins to form a taut, endless pulley. Alternately, the pins can be eliminated and the frame slotted to receive the cord. Two end point markers are attached to the cord, one on each run of the pulley circuit. The end point markers abut at the center point marker on the frame. In use, the end point markers are adjusted to match the ends of the object in question. Since the displacement of each end point marker from the center point is equal, the center point marker indicates the center point of the object. Additional features provided are a lock screw to hold the index markers in one position, and a fine tuning adjustment to make fine corrections to the end point marker positions.
A positioner for positioning a partition or a divider at a predetermined position in a cabinet, such as for mounting a pair of drawers. The cabinet includes left and right side walls. A partition holder mounted on a frame holds the partition parallel to the left and right side walls. A left slider, slidingly mounted to the frame, includes a left jaw, and a right slider, slidingly mounted to the frame, includes a right jaw. The sliders are coupled such that longitudinal sliding movement of either slider moves the other slider an equal and opposite distance and such that positioning the left jaw to abut and align with the left side wall and positioning the right jaw to abut and align with the right side wall positions the partition holder at a predetermined holding position between the left and right side walls.
The center locator tool has a flat, rectangular case with a top wall, a bottom wall, and two opposing side walls. The interior of the case houses a spur gear rotatably mounted on a center post extending through the center of the case, the center post having a bore defined axially therein. A pair of arms are mounted so that the arms are slidable through the case on opposite sides of the spur gear, each arm having a rack defined in its edge which engages the spur gear so that when one arm is extended from the case, the other arm is extended an equal distance in the opposite direction. Each arm has a groove defined in its bottom surface for engaging a guide projecting from the bottom wall of the case. The end of each arm has a work engaging plate forming a "V" shape, the opening of the "V" facing towards the center of the tool, the plates depending from the ends of the arms and being adapted for engaging a square or circular workpiece. When the "V" plates engage the diagonally opposing corners of a square or opposite sides of a circle, the center of the surface lies below the bore defined in the center post. An alternative embodiment of the tool has a wheel with an O-ring about its circumference frictionally engaging slots defined in the edges of the arms in place of the spur gear and rack mechanism.
A level is disclosed with a sliding measurement system. The level includes a planar upper surface, a planar lower surface and a web extending between the upper surface and the lower surface. The web includes at least one elongate channel to which a track having an inwardly facing slot is mounted. The level further includes one or more pods slideably received on the track in the inwardly facing slot. The pod includes a generally cylindrical female member having upper and lower ridges extending outwardly therefrom, and a generally cylindrical male member configured to receive a marking instrument, the male member being matingly received in the female member. The upper and lower ridges of the female member are configured to be received in the inner slot of the track and are slideable thereon. The level further includes at least one bubble level vial mounted to the web of the body of the level.
