Abstract:
A tool drills holes into different sized wooden blocks so that the holes are precisely positioned while providing a means to position the tool to match an existing line or slot on the wooden block. The tool includes two identical pieces that, when assembled, adjusts to accommodate variable sized model car blocks, provides a view port to look through the tool for positioning, and contains perfectly aligned drill guide holes on either end and in the middle of the assembly to guide a drill bit that drills the required holes needed to accurately place axles and eyelets into the model car. The tool is adjustable to accommodate different sized blocks. The holes can be angled to create wheel camber when axles inserted.
Abstract:
A system is provided for matching a new hole in an overlying member with an existing hole in an underlying member. With a magnet placed in the existing hole, an indicator device having an internal cavity, an outer boundary, and a ferrous ball freely movable within the internal cavity is slid across the surface of the overlying member and in engagement therewith. When the ferrous ball overlies the magnet, a position on the overlying member aligned with the existing hole in the underlying member is thereby located. Thereafter, the indicator means is removed from the overlying member and replaced by a drill guide means. The drill guide means is used to locate a drill to cut a hole through the overlying member coincident with the existing hole in the underlying member.
Abstract:
A pair of metal longitudinal members (herein called "tubes") having spaced holes along their lengths are held in place lengthwise against a wooden utility pole by means of spring-tensioned chain tighteners. A plurality of V-shaped brackets are slideably connected at their ends across the tubes, the brackets having positioning pins in their ends for insertion into the holes of the tubes. Interchangeable bushings for different diameter drills are affixed to the V-shaped brackets. Preferably, a top support bracket having a pipe which fits on top of the pole is affixed across the upper ends of the tubes. The V-shaped brackets can be slid up and down the tubes so that holes can be drilled at precise distances from the top of the pole and from one hole to the next.
Abstract:
A tool for layout and machining operations that incorporates an end plate for locating the tool with respect to a datum point, and beam means for slidably mounting a carriage for movement with respect to the datum point. The carriage is provided with means for fixing the carriage in relationship to a scale bar that contains a plurality of protruding locating balls. The carriage is located with respect to a ball thereby determining the incremental position of the carriage along the beam. Fine adjustment of the carriage position is accomplished by movement of the scale bar within the beam and thereby the movement of the carriage affixed thereto. This movement is measured by a standard micrometer. The carriage contains provision for receiving bushings or other means for locating a point at which machining is required and thereafter receiving a tool bit for accomplishing the machining operations.
Abstract:
A lock and pin for the structural and fluid tight repair of cracks not amenable to high temperature repairs or synthetic material patches. Fluid tight pins and locks seal the crack while one or more locks prevent the crack from growing. These repairs need to endure the remaining life cycle of the machinery part while withstanding all the strain, pressure, heat and expansion and contraction of the part before the crack(s) were formed. Often these cracks evolved due to engineering design flaws that will require even greater strength from these areas than when new.

Abstract:
A fastener for fastening a drill jig to overlapping work pieces and clamping the overlapping work pieces for facilitating accurate drilling of the overlapping work pieces including a fastener body and a damper assembly operatively connected to the fastener body. The damper assembly is configured to enable application of a first load to the drill jig, and the fastener body is configured to enable application of a second load to the overlapping work pieces when the fastener fastens the drill jig to the overlapping work pieces. The first load is less than the second load. The first load is sufficient to hold the drill jig to the overlapping work pieces during drilling but without causing significant deformation of the drill jig. The second load is sufficient to reduce the formation of burrs during drilling of a hole through the overlapping working pieces.
Abstract:
A match drilling tool comprising a body comprising a drilling leg and a fixing leg, said drilling leg being separated from said fixing leg by a gap, wherein said drilling leg defines a cutter guide opening, and wherein said fixing leg defines an alignment pin opening, said alignment pin opening being concentric with said cutter guide opening; and an alignment pin slideably received in said alignment pin opening.
