Abstract: A hand-held tool for spacing clapboards that includes a speed square tongue located in the top center of the device. This feature allows a user to quickly and accurately transfer both horizontal and vertical lines, revealing material to be removed around doors and windows. There is a trigger mounted on the ergonomic handle that both locks the tongue in place for transferring horizontal lines, and releases the tongue for transferring vertical lines. Two trays are adjustable in ¼? increments that use pull pins under the trays. The trays can be adjusted for any board up to 10? in height. Desired overlap is achieved by adjusting the position of the bottom tray as desired. Finally a ruler is provided along the side of the tool. A second model that has no handle is also taught.

Abstract: The present invention provides methods for the manufacture of body line templates, and for the use of those templates to repair the body lines of motor vehicle body panels. The present invention improves body line repair by restoring body lines more precisely and in the fraction of time it would typically take. Templates are often used in the industry to cut and forge body panels or body panel pieces, but not for repairing body lines. The original pattern for a body line template is made from an undamaged, perfectly contoured panel, such as a quarter panel, door panel or fender. The body line templates are used as a guide to restore the original shape of the body line on a damaged body panel. The templates are also used as a guide to more easily perfect the body lines by manipulating the applied body filler. In this way, repair time can be reduced by fifty, or as much as seventy-five, percent.

Abstract: A three-dimensional coordinate measurement apparatus capable of reducing shaking of a Y carriage and improving measurement accuracy. The Y carriage is supported by two strut members which are across a surface plate and movable in a Y-axis direction. The two strut members include a first strut member having a driving mechanism and a second strut member which moves following the first strut member. A guide portion parallel to the Y-axis direction is formed in the surface plate on a first strut member side. Side surface support members support the first strut member on the surface plate by holding both opposed side surfaces of the guide portion. The driving mechanism includes a roller having an axis perpendicular to a surface plate surface, and the roller is brought into contact with one side surface of the guide portion and rolled to move the Y carriage relatively to the surface plate.

Abstract: A quilt stamps and quilt stamp sets can be used to simplify and expedite the process of cutting and sewing fabric pieces for a patchwork quilt. A quilt stamp can be formed of a transparent material in a desired shape. A stamping side of the quilt stamp includes parallel ridges that are offset from and extend along the outer edges of the shape. The outer ridge can be formed as a continuous ridge while the inner ridge can include repeating gaps thereby forming a dashed pattern. Both the outer and inner ridges can function to stamp lines onto fabric which define where to cut as well as where to sew the fabric.

Abstract: A device and method for measuring the amount of knee extension loss, hyperextension, or extensor length associated with arthritis, trauma, surgery or other medical conditions. This device and method includes measuring the difference in heel heights of a patient while patient is lying prone on a table with their legs, at the level of their knee caps, off the table. This device and method also measures extensor length in a patient's knee joint, by assessing heel height difference while a patient is lying prone on a table with a prone knee bend. This device and its methods provide accurate distance measurements that correlate to knee straightness and flexibility; these distinguishing metrics are unattainable by a standard “disc” goniometer. In addition, this device permits convenient measuring of a knee's mobility for two unique perspectives, namely in prone with legs straight or with a knee bent.

Abstract: Workpiece-holding tools and techniques are described. Workpiece-holding tools and techniques are usable to ensure consistent and durable alignment of various workpieces while providing access for performing attachment techniques thereon. In one example, the workpiece-holding tool is configured to allow objects to be held or removably affixed to an alignment surface. Holding objects with the workpiece-holding tool ensures that the alignment of objects with an alignment surface does not change while a user is operating upon a workpiece, e.g., as by joining aligned objects together, without interfering or obstructing access to the objects. The ability to hold objects is enhanced by the inclusion of cutouts that provide increased access to interior surfaces of the workpiece-holding tool, such as to increase the area available for use of clamps or other fastening devices.

Abstract: A wall plate bracket includes integral straight edges used to quickly, easily and precisely define an area on a wall where a wall opening for the bracket is to be cut. The integral straight edges are formed along a top or bottom edge and a side edge of a generally rectangular front face plate of the bracket. The front face plate is held against a wall, and an L-shaped line is drawn along the straight edges. The bracket is then rotated 180 degrees and the ends of the straight edges are aligned at the ends of the previously drawn line. Another L-shaped line is then made or drawn along the straight edges, resulting in the two drawn L-shaped lines together forming a proper rectangle defining the wall opening to be cut.
