Abstract: An apparatus and method for efficiently inscribing positioning marks on a ring band, including a positioning plate having a pattern of scribe holes defined therein, wherein the pattern of scribe holes is arranged to permit a jeweler to inscribe positioning marks on a ring band based on a number of desired scribe locations chosen from the pattern of scribe holes. A positioning lever is centered above the positioning plate and includes a positioning needle for placement into a scribe hole chosen from among the pattern of scribe holes, and an angular marker for inscribing positioning marks on a ring band positioned below the positioning lever in a central location of the positioning plate. A ring band mount for maintaining the ring band rigidly in place while the angular marker is utilized to inscribe a positioning mark on the ring band.

Abstract: An illuminated centerpunch designed to illuminate the area on a workpiece where a punch mark is to be made. The centerpunch includes a hollow, cylindrical-shaped main body. Attached to the proximal end of the main body is a replaceable striking cap. Disposed inside the main body is a bulb holding collar acts as a switch and which holds a plurality of bulbs. Attached to the distal end of the main body is a post assembly designed to hold a replaceable tip and the bulb holding collar inside the main body. Attached over the distal end of the main body and around the replaceable tip is an optical end assembly. The optical end assembly includes a ring plate with a plurality of radially, spaced-apart arms which extend distally and curve inward from the main body. Located inside each arm is a fiberoptic capable of transmitting light produced by the bulbs located inside the main body to a desired point on the work surface. Disposed inside the main body are batteries electrically connected to the bulbs.

Abstract: A gauge is disclosed to grid in the location of sprinkler lines above grid type suspended ceilings. The gauge is used after the grid is installed but before the overhead sprinkler system is completed and before the ceiling tiles are installed. The gauge includes a plurality of arms, preferably three which have lengths approximating 1/2 of the grid opening dimension and are all pivotal and extendable, if necessary to engage the grid system and locate a central body to which the arms are secured. When extended, the arms define the center of the grid opening. An extendable arm is secured to the central body and may be manually extended upward to locate the center of the grid opening at the structural support for the sprinkler distribution system. A drop branch line from the distribution system at the location identified by the gauge is installed and a sprinkler head attached to the drop branch line.
