  • Patent number: 10593228
    Abstract: A penmanship device is provided to assist students learning to write consistently and evenly. The device comprises a body with a handle portion and an operational portion. The operational portion has at least two windows. A first window is used for alignment and a second window is used to write. A user writes a first letter of a first word within the confines of the second window. To write the next letter, the device is shifted so that an edge of the previous letter is aligned with a left lateral edge of the second window. This is repeated until the word is completed. To write the next word, the device is shifted so that an edge of a last letter of the previous word is aligned with a right lateral edge of the first window. In another embodiment, the device has three windows providing left-handed and right-handed support.

    Abstract: The Chappell Universal Square™ solves the problems associated with standard framing squares and provides a dynamic framing square bearing novel indicia and a novel arrangement of same for direct application to framing members during construction of complicated framing systems of equal and/or unequal pitched members. Typically, squares are limited to use with a single base unit of measurement, e.g. inches or millimeters, and provide limited tabulated information for use in calculating lengths, distances, and angles at which to cut framing members. The present invention is a tool that provides universal applicability for use in building both simple and complex structures according to metric and standard/imperial measurement systems. The present invention provides tabulated calculations aligned with indicia that enable construction of equal and complex unequal pitch framing members without necessitating the execution of complex trigonometric calculations.

    Abstract: The framing square apparatus provides immediate visual confirmation of a square relationship between two spaced apart surfaces or points. A user need only visually reference the position of the line between squares of the apparatus to determine such. The apparatus is provided with two squares, three squares, or four squares. The number of squares determines the number of points that can be established in square relationship. The line is selectively tied or knotted through the orifice of each square, as desired. The apparatus saves considerable time in determining square between two points, surfaces, corners, or the like. And, using more than two squares provides reference of additional points.

    Abstract: A dadoing system that can be set up to cut multiple dados in a workpiece. The dadoing system uses a sliding channel clamp to keep the workpiece from moving in a transverse direction, while the dados are being cut into the workpiece. The sliding guide rails are used to put downward pressure on a workpiece while guiding a router across the workpiece during the dadoing process. Once the system is set up to cut the dados in the desired locations on the workpiece, the sliding guide rail stops can be secured into place. The stops will insure that the sliding guide rails are set up in the same place thus allowing multiple workpieces to have matching dados that line up properly during assembly.

  • Patent number: 6725556
    Abstract: A rafter tool and method includes a rafter square portion, a base portion, an extension member, an L-bar and a support bracket. The extension member, such as a string, may be wrapped within the base portion during storage of the rafter tool and can be extended between two points for laying out a rafter board. The square portion may be integrally attached to the base portion and is used for providing angular and distance measurements. The L-bar and support bracket can also be stored within the base portion and are used when laying out rafters. The method includes using a floor surface, a stud wall, or a building to lay out the rafter boards.

  • Patent number: 6725559
    Abstract: The tool for locating a center mark for embroidery on articles such as garments includes a planar body having orthogonally-related legs with respective exterior and interior edges. Index markings are provided on the legs along the linear edges. The index markings include indicia identifying a plurality of corresponding preestablished garment sizes along the linear extending edges, respectively. By aligning common selected sizes along the edges with the vertical centerline of a folded garment and a shoulder portion of the garment, respectively, the location of the embroiderer's center mark on the garment is identified at the intersection of the linear edges. The interior edges of the tool may also used to form marking lines where conventional hoop grids are not available.

  • Patent number: 6643945
    Abstract: A universal anchor bolt template including a plate member having a square configuration. The plate member has planar upper and lower surfaces. The plate member has a plurality of apertures therethrough arranged in at least one group of four radial aperture lines. The apertures are spaced along each of the aperture lines in the group at corresponding distances, such that the use of corresponding apertures allows the anchoring bolts to be positioned in a square configuration with a selected center-to-center distance. Each of the apertures is surrounded by at least one concentric knock-out for allowing the apertures to be enlarged for the use of larger anchoring bolts than could be accommodated by the apertures.

  • Patent number: 6622395
    Abstract: A measuring device is used to orient and place portions of obstacles, such as pipes, conduits or the like and includes a framing square having an alignment bracket mounted thereon. The alignment bracket abuts one of the obstacles and one leg of the framing square is located adjacent to the other obstacle. The framing square then defines the location and path for a coupling element, such as an elbow or the like, used to couple the obstacles together.

  • Publication number: 20030145475
    Abstract: A layout tool for laying out or “marking” positions at a predetermined spacing for the attachment of studs having a nominal thickness to a length of dimensioned lumber comprising a plate, when framing walls during construction of a building. The layout tool includes an elongated rail for placement against the plate, and a first stud marking guide extending perpendicularly from the elongated rail. The first stud marking guide has left and right side edges, and width between the side edges corresponding to the nominal thickness of the studs. A separate stud marking guide extends perpendicularly from the elongated rail. The second stud marking guide likewise has left and right side edges and a width between the side edges corresponding to the nominal thickness of the studs. The left edge of the second stud marking guide is spaced from the left edge of the first stud marking guide a distance equal to the predetermined stud spacing.

  • Patent number: 6591511
    Abstract: An improved framing square having integral features for automating the marking and cutting of angles. The square contains two sliding carriages—one in the body and one in the blade. Each carriage has a deployable pin. In order to set an angle, the user first deploys the pins in each sliding carriage so that they protrude downward from the square. Next, the user sets the sliding carriage in the body to the desired position and locks it in place. The user then sets the sliding carriage in the blade to the desired position and locks it in place. The two pins protruding from the sliding carriages are then butted against the board to be cut. Once they are in place, the blade of the square will form the correct cutting angle across the board. Since many common cuts employ a twelve inch base leg, the invention includes another feature: Rather than set the sliding carriage within the body to twelve inches, the user may opt instead to deploy a fixed pin located in the body at the twelve inch position.
