Abstract: An L-shaped sine plate is mounted to pivot about an arcuately translating pivot point to maintain the sharp corner height at a constant elevation. In this way, no mathematical formulae need be used to calculate adjustments which would otherwise be necessary if the sharp corner height was changing, as is the case with other sine bars.

Abstract: An adjustable tool, and method of use thereof, for use in cutting a workpiece having a face extending between first and second opposite borders is disclosed. The tool preferably comprises an elongate guide member having proximal and distal ends, a bottom surface and a primary side including a straight-edge; a post fixed at the proximal end; an arm extending from the guide member, having measurement indicia marked thereon and defining a slot; and a movable pin positionable in the slot, the pin adapted to be secured at a desired location corresponding to a desired measurement indicium. The post and the pin are adapted to simultaneously contact the first border of the workpiece so that the straight-edge identifies a desired cutting line corresponding to the desired measurement indicium.

Abstract: The gage has a body made of flat plate which has a reference edge. Another edge is a gage edge which is angular and defines a sharp apex away from the gage edge. A foot is slidable along the gage edge to rotate the gage body around the sharp apex pivot. Indicia indicate the angle at different foot positions.

Abstract: This invention provides an angle gauge that, when used in conjunction with a caliper or other linear measuring device, improves both the precision and ease with which angles can be measured and set by allowing the user accurately to measure and set angles in fractions of degrees. Using the gauge, an angle formed by the gauge may be determined or set by reference to the linear distance measured by the caliper. Calculations or tables can be used to convert the linear measurements into the angle setting or measurement with great accuracy, or the capacity to calculate the angle corresponding to the linear measurement can be built (i.e. programmed) directly into the device.

The alignment member is movable with respect to the clamping member to receive the golf club shaft in a cradle.

Abstract: A pipe angle measuring tool and pipe angle marking tool are defined. A template is also defined which is a flexible substrate, such as paperboard, on which images of the tools are printed. A user may create the tools by cutting them out of the paperboard with ordinary scissors or by separating lines of weakness provided in the substrate. The tools are useful in measuring an angle between two pipes and marking the angle on a part of a selectable angle pipe elbow. The template is inexpensive to produce and can, therefore, be provided to purchasers of selectable angle pipe elbows at little or no charge to the purchaser.

Abstract: A device for measuring angles, primarily for measuring bending angles attained by press brakes and similar when a piece to be worked is bent between upper and lower pressing tools (1), includes an oscillating device (6) that detects the angled position of the piece to be worked. The detection device comprises a rocker (6) that is connected directly to a detecting mechanism (12) such as, for example, a rotating potentiometer. The rocker is arranged to pivot around an axis (5) that runs parallel with the longitudinal axis of the lower pressing tool. In its turn, the axis shaft (5) is supported by a supporting and displacement device (3, 4) that can displace the axle, and thereby the rocker, towards and away from the piece to be worked at an oblique angle to the relative direction of movement of the upper and lower pressing tools.

Abstract: A multi-purpose measuring tool has an elongate base and arm pivotally connected at rounded ends thereof in an angularly variable relation to perform multiple functions, including measuring inclines, measuring corner angles, measuring distances, use as a square, use as a bevel gauge and use as a torpedo level. A retractable measuring tape housed within the arm has a terminal finger gripping end adapted to be pulled away from the arm and removably attached to a distal end of the base. The measuring tape is dual purpose in that one side of the tape is used for determining the angle of the arm relative to the base to perform some of the above functions, and the other side of the tape is used for traditional linear distance measurements. The tool's base includes a “vertical” bubble level and the arm includes a “horizontal” bubble level to perform some of the above functions.

Abstract: An angle measuring device used for measuring the pendulum angle of a cable of a lifting device comprising connection components which utilize measurement value pick-ups and are connected via a cardanic-type joint to axles which are arranged at right angles to one another. To attain high precision of discrimination in measurement, the measurement value pick-ups each comprises a Hall sensor and an associated magnetic element to create a magnetic field detectable by the Hall sensor. An angle of measurement can be attained if the lower connection component is swung and causes a shift in the joint ball around the axle. This results in a change in the position of the magnets relative to the Hall sensors. This change in position results in a change in the detected Hall voltage which after appropriate adjustment can be transformed into an angle measurement.

Abstract: An adjustable angle instrument for high precision craftsmanship is configured from a pair of similar metal sector parts, each having a sector shape with a wide double flange along a straight edge. The two sector parts are accurately pivoted together in an apex region. Each flange is made to have accurate surfaces on its outer surfaces on which the instrument may be stood in a vertical position or laid horizontally on a flat surface such as a saw table. The flanges may be set to any angle between 45 and 90 degrees as indicated by a calibratable hairline cursor, and the angle may be captured by locking the two sector parts together by tightening a knurled brass knob. One of the sector parts is also provided with an edge which is accurately machined at 90 degrees relative to the flange and thus may be set to any angle between 0 to 45 degrees relative to the other flange, providing the instrument with a total range of 0 to 90 degrees.

Abstract: A workpiece is secured to a support or gang plate which is positioned at an acute angle relative to a base plate by a pair of hollow support blocks or cubes and corresponding angularly adjustable locator plates. The base plate, gang plate and support cubes have precision X-Y grid patterns of threaded holes and precision bores for use with a modular tooling system. Each locator plate is pivotally supported by a dowel or pivot pin projecting from the adjacent support cube and is precisely positioned by a selected gage block which contacts another dowel pin projecting from the adjacent support cube. Cap screws extend through arcuate slots within the locator plates and secure the locator plates to the corresponding support cubes after the gang plate and workpiece are positioned. The locator plates may be reversed on the pivot pins to provide for selecting smaller support angles.

Abstract: An angle measuring instrument provides two straight arms connected at one end for relative pivotal movement. A telescoping assembly includes two elongated telescoping members each providing a free end. The free end of one telescoping member is pivotally connected to one arm and the free end of the other telescoping member is connected to the other arm. The telescoping members provide scales indicating the angular position between the two arms, the distance between the pivots of the free ends of the telescoping members on the arms, and a correction to be added to or subtracted from measurements along the length of the arms to establish distances from the corner which is being measured. The two arms can pivot through a full 360 degrees relative to each other, permitting the measurement of inside and outside corners of all sizes. A straight edge is removably mounted on one of the arms when measuring outside corners.

Abstract: A combination simple and compound mitre gauge constitutes the subject matter of the present invention. The mitre gauge is intended to be utilized with power woodworking tools.

The support plate presents a vertical surface which mounts a guide that can be moved into one of two positions to vary the length of it. The guide may also be removed and a planar surface presenting shoe pivotally coupled with the support plate. The angle of the planar surface of the shoe may be varied and means is provided for locking the shoe in any given position.
