TECHNICAL FIELD

The present invention relates generally to layout tools, and more particularly to layout tools having calibrated offsets for applications such as the coiHnear marking of woodworking joints and other such work pieces.

BACKGROUND ART Laying out and marking workpiece such as wooden board during various activities such as joinery requires the carrying of precise layout or measurement marks from one surface of a workpiece to another without the introduction of measurement inaccuracies or the compounding of error. Such errors are commonplace due to the multiple steps, tools, measurement and markings typically required to carry a mark around a workpiece or to other workpieces to be joined together. These layout errors are often compounded by the variable thickness of the marking utensil used, with small errors adding up significantly after just a few measurements and marks.

These layout errors are often dealt with by a skilled eraftsperso through a variety of compensating techniques, many of which simply involve estimation and a keen eye. The choice of marking utensil can help, but no eliminate, such layout errors. Layout error can make the simple task of accurately marking a work piece such as a rectangular board time consuming and frustrating » or result in a waste of material.

For example* a dovetail joint is typically, although not exclusively* used in woodworking to join two planar components together at a right angle. Often the joining of the sides of a wooden box or drawer employs the use of dovetail joints. Dovetail joints are commonly seen joining the sides of a drawer to the front face of the drawer. When joining two planar components such as boards, a series of‘‘pins” are cut into the edge of the first board and a serie of“Tails” are cut inf the edge of the second board. The pins and tails each have a trapezoidal .shape. The pins of the first board are then interlocked with the tails of the second board, forming an extremely strong and durable joint, especially when glued together, without the need lor mechanical fasteners.

The dovetail joint is also referred to as a fantail joint, culvertaif joint, swallowtail joint, simply dovetail, and the like. This joinery technique dates back to ancient times, and is evident in ancient Egyptian architecture as well as at ancient Egyptian an Chinese tombs.

While the dovetail joint is very strong due to its inherent shape, and nearly impossible to pull apart when glue Is used, it Is a difficult joint to make manually. The traditional method is to cut one hoard and then use it as a template of sorts to mark the mating board.

Consider that the cratisperson is attempting to hold two potentially wide, long, and heavy boards at a perfect right angle with the edges in perfect registration and trying to mark the opposing side of the joint while working inside the confined spaces between the pins or tails;. Any slight movement, distortion of the parts, a doll pencil or even an uncomfortable stance will introduce errors resulting in ill-fitting joints. Such problems exist with many types of joinery, fabrication, and production in wood and other materials such as metal, plastic, and the like.

What is therefore needed are layout tools with offset surfaces calibrated to a marking utensil that allow for error free marking of a workpiece or multiple workpieces without dependency on the workpieces as a reference or the use of compensating techniques that may not be reproducible across materials, processes, or craftspeople.

DISCLOSURE OF THE INVENTION in accordance with the present invention, there are provided layout tools with calibrated offset surfaces to provide for the eolimear marking of a workpiece or multiple workpieces across multiple surfaces.

The .foregoing paragraph has been pro vided by way of introduction, and is not intended to limit the scope of the invention as described by this specification, claims and the attached drawings.

The offset surfaces are calibrated to a marking utensil appropriate to the intended task.

The device of the present invention provides precise registration using physical contact of the tools in relation to each other and to the workpiece and eliminates the potential errors that are introduced each time a tool is repositioned to complete a line, or one layout tool is put down to pick up another. The tools of the present invention are .registered ONCE and used to draw layout lines on multiple faces of a workpiece. See tor example Figures 33-35 and the associated description herein . in a method of the present invention boards to be joined l r example are secured face to face using a vice or damps. Once secured in a. perfectly solid position joint spacing marks are established on the hoards simultaneously. The boards are then marked using the calibrated layout tools of the present invention, ensuring perfect registration of all layout lines. A skil led craftsman cutting along each layout line will produce perfectly fitting joints, eliminating the error-inducing steps present in traditional methods,

While various embodiments of the present invention are described and depleted herein, each embodiment comprises a calibrated edge or face that enables error free coIHuear marking. The term calibrated indicates that the edge or face is correlated or in conformance with a known standard.

Figures 33-35 illustrate examples of how to use various embodiments of the calibrated layout tools of the present invention.

The calibrated layout tools presente here are unique in that the approach to laying out and marking the joinery is accomplished across multiple surfaces (of a wooden board for example) using physical registration instead of numerous rounds of measurement and marking. There arc many possible configurations and embodiments of the tool of the present invention, making each applicable to specific tasks. These include square (90 % angled (other than 9(F and flexible, pivoting, or hinged configurations using a variety of lengths, widths, and thicknesses in the various parts making up the task-specific devices. The parts also include angled or otherwise shaped surface in various combinations to achieve the. offsets that provide the colliueaf marking utility of the de vices.

The tools provide eollmear marking of workpieces through calibration to a marking device of specific size. The calibrated offsets may be scaled to accommodate a wide range of marking de vices in a wide range of sizes. The tools of the. present invention eliminate potential errors that are introduced each time a conventional measuring device (he.: a ruler or square? is moved to complete a line or one calibrated layout tool is put down to pick up another. The tools of this invention are registered ONCE and used to draw colfinear layout lines on one or multiple faces of a work piece. in on method for marking a line carried to multiple surfaces of a board for example, a crafisperson will measure and make a mark at the desired position of the line and place a square on the mark. After striking a line with a calibrated marking utensil and without moving the square the crafisperson will place the offset, surface of the calibrated layout tool against the square and across the adjoining edge of the work piece. The calibrated offset built info the tool allows the marking of the adjacent and opposing faces in perfect registration with the original line without additional measuring.

In one method using angled calibrated lay out tools (to mark do vetail joints for example) opposing boards are secured face to lace using a vice or clamps and in that perfectly solid position the joint spacing is established on both the pin AND tail boards. The boards are then marked for joinery using the calibrated layout tools of the present invention ensuring perfect registration of layout lines on all parts A skilled craftsperson cutting to each layout line will produce perfectly fitting joints, eliminating the primary error-introducing steps of conventional methods.

It is therefore, apparent that there has been provided, in accordance with the various objects of the present invention, a layout tool with calibrated offset surfaces to provide for eollinear marking of work piece or multiple work pieces.

While the various objects of this invention have been described in conjunction with preferred embodiments thereof it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternati ves, modifications and variations that fall wi thin the spirit and broad scope of this specification, claims and drawings appended herein.
