Abstract: A hand tool enabling self-aligned placement and post alignment clamping of a surface mounted tooling element and a method for manufacturing such a tool. Using an additive manufacturing process, a tool housing may be manufactured in which one or more internal voids allow insertion and rotational movement along and about a longitudinal axis of the housing, respectively, of a member having a radially extending portion. A handle and a brace may be coupled to the proximal and distal ends of the member to facilitate operation of the tool and placement of the surface mounted tooling element, respectively. Such member may also be spring loaded to enable the tool to clamp itself to a workpiece during the mounting operation, with the radially extending member portion limiting rotational travel of the brace.

Abstract: A panel installation tool is provided that includes a first portion configured to releasably engage with a panel, a second portion attached to the first portion and configured to releasably engage a structural component to retain the first portion with respect to the structural component, and a location indicator configured to enable marking on a panel surface a location through which a retaining element may be used to retain the panel to the structural component.

Abstract: A method and apparatus for identifying locations for holes for a stackup of parts. In one illustrative example, a required edge distance for a hole for the stackup of the parts is identified. A measurement tool is selected based on the required edge distance identified for the hole. The measurement tool comprises a circular section having an edge and an indicator centrally located with respect to the edge of the circular section. The edge of the circular section of the measurement tool is associated with a part in the stackup of the parts. A location on the part for a center of the hole for the stackup of the parts is identified using the indicator.

Abstract: An alignment system and method for aligning a hole-making device for forming a hole in the ground. In one example, the alignment system includes an alignment template selectively securable to the ground; and a centering plate positionable within the alignment template, the centering plate having a hole adapted to be positioned on a survey pin or nail or other mark. The alignment template is aligned relative to desired marked hole location, and the hole making device is aligned relative to the template, which thereby aligns the hole making device relative to the marked hole location.

Abstract: A marking system for cutting an aperture for pipe clearance has a pipe and a pipe stamp. A stamp posterior side has a posterior aperture fluidly connected to an interior cavity. A first rubber stamp projection has an annulus that projects out and away from the stamp anterior surface. A second rubber stamp projection is centrally located on the stamp anterior surface having a general shape of an “X”. The pipe stamp slides over an end of the pipe via the posterior aperture. The first rubber stamp projection and the second rubber stamp projection are placed against a surface for applying a mark for cutting an aperture for pipe clearance.

Abstract: An apparatus for locating at least one site on a first side of a workpiece in a predetermined relation with at least one aperture located on a second side of the workpiece includes: (a) at least one first locus-fixing structure; each respective first locus-fixing structure of the at least one first locus-fixing structure being configured for effecting the locating at least one respective site of the at least one site; (b) at least one second locus-fixing structure configured for cooperating with the at least one aperture to substantially fix the at least one second locus-fixing structure with respect to the workpiece in an installed orientation; and (c) a substantially rigid connecting member coupled with the at least one first locus-fixing structure and the at least one second locus-fixing structure. The connecting member situates the at least one first locus-fixing structure substantially in the predetermined relation in the installed orientation.

Abstract: An electrician's center point device to simplify placing conduit holes in electrical enclosures wherein a device is provided having a stamp to imprint the center point of the conduit to the electrical enclosure. Diametric lines are drawn through the center point to facilitate the positioning of a conventional knockout set on the sidewall of the electrical enclosure for pulling a hole for a conduit there through.

Abstract: A method and apparatus that will locate the center of a circle in a single operation by positioning two points of registration at the edge of the circle relative to a third point of registration previously set at the edge of the circle where these points are held in accurate spatial relationship to each other and a fourth point of registration that in turn, indicates the center of the circle. By allowing precise registration and novel operation, this invention provides a simpler, more accurate means to locate the center of a circle that precludes the need to make extraneous marks on the circle being measured.

Abstract: 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.

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.

Abstract: An electrician's center point gauge to facilitate placing conduit holes in electrical boxes wherein a circular disc is provided having a center hole and four 90.degree., circumferentially spaced notches in its peripheral edge. A trace is made of the circumferential edge of the disc, notches and center hole. Diametrical lines are drawn through the center of the circumferential trace and notches to facilitate the positioning of a conventional knockout set on the side wall of the electrical box for pulling a hole for a conduit therethrough.
