Abstract: The invention is includes a series of dimensional scales (linear measuring device) on the top surface of a miter saw table. The scales allow for measurements to be located or obtained on the saw table relative to the saw fence and relative to the saw blade. The scales may replace the need for a hand held tape measure or ruler for measuring or marking the saw table surface when cutting crown molding or other materials. The scales could be placed on or in a saw during production by a manufacturer. The scales could be placed on or in a material to be placed on a saw during production by a manufacturer. The scales could be placed on or in a material to be placed on an existing saw.

Abstract: A tire tread gauge shaped like a rectangular card that fits easily into a credit card slot in a wallet or purse. The card has a tread measurement scale imprinted, engraved, molded or otherwise marked onto one or both sides and is used to measure the remaining tread depth on motor vehicle tires. Other possible embodiments include a card with more or less than 4 sides or a round card.

Abstract: A tool for measuring movement of a strand of a chain extending between sprockets in a direction substantially transverse to the length of the strand, for example a primary motorcycle chain extending between a clutch sprocket and an engine compensating sprocket, wherein the movement of the chain needs to be adjusted at intervals, includes a handle section by which the tool is held and manipulated by a user. A chain engaging section is joined to the handle by an indicator section so that a user holding the handle can manipulate the chain engaging section to engage the strand of chain whose movement is to be measured. Movement of the tool will then move the chain. Indicia on the indicator section is usable to determine the movement of the chain. The tool can also be used to measure the tension of a belt or other material.

Abstract: An instrument for measuring the size of a testis has a pair of relatively displaceable jaws with testis contacting surfaces. The spacing between the jaws is displayed on a scale calibrated to a recommenced dose of a chemical sterilant at a given concentration for the testis measured for sterilizing a male animal having scrotal testes. The instrument is used to determine the appropriate dose to be administered the animal, each testis of which should be independently measured as the size of the testicles may different in the same animal.

Abstract: A device for measuring and marking lines and points on a steel I-beam includes a rib for contacting the outside of an I-beam flange along a line opposite the center of the beam web, a measuring blade that rests on the beam web and measures distances from the outside of the flange, and a bridge for connecting the measuring blade to the rib in a way in which the measuring blade is held perpendicular to the flange. The device marks I-beams faster and more accurately that was possible using prior art tools and techniques.

Abstract: Apparatus and method for measuring cables of varying diameters to be used in a wire bundle. The apparatus involves a support platform having a groove formed therein which is laid out to have at least one U-shaped turnaround portion. The groove is further canted such that it opens at an angle of about 4.85° away from an interior area defined by the U-shaped arc. This allows cables of varying diameters to be placed in the groove during measuring and automatically compensates for the differences in diameter of the cables. Thus, each cable laid into the groove and measured in accordance with the length of the groove will have the same length, regardless of differences in the diameters of the cables.

Abstract: A securing arrangement for transporting and mounting a measuring system used for the determination of the position of two components, which can be moved relative to each other. The securing arrangement includes a base body, which is linearly displaced along a displacement direction via a guide track of a support body of a measuring graduation of the measuring system and is fixed in place on the support body by clamping forces in order to maintain a mounting base that fastens a scanning device to one of the two components in a desired position in relation to the support body. A service element is provided on the base body and having an operating section for introducing and/or canceling the clamping forces, wherein the operating section of the service element laterally protrudes past a surface of the base body which faces away from the support body and is laterally bordered by a lateral edge, when the base body is fastened on the support body.

Abstract: A router and other cutting tools with a fixed center such as drills, shapers, milling machines, etc., used for cutting wood, metal or other materials, is provided with a fence mechanism for either a table or the base of a portable tool, for rapid and easy settings of the fence with respect to the center of the cutting tool. This is accomplished by a pivot mounting of the fence on a table or on a portable tool base, with respect to a block pivoted to the table or tool base, wherein the center of the pivot for the block and the center for the pivot for the fence are on opposite sides of the cutting tool and located on a line which passes through the tool center and the respective pivot locations. The desired spacing of the fence to the tool can be achieved using accurate spacers between the fence and the block, even with the tool being mounted in place.

Abstract: A plate-like guide for precisely positioning a plunge router for the purpose of boring a series of holes in a work piece. The plunge router is provided with a guide bushing having an outside diameter, centrally positioned in the router working face, through which the router cutter can be pushed (plunged). The boring guide is provided with a series of spaced pilot holes positioned on a center line. The inside diameters of the pilot holes are a close sliding fit with the outside diameter of the router guide bushing. The boring guide has five positioning means usable in pairs to precisely position the boring guide with respect to the workpiece. There are two groups of fence holes into which fence pins are screwed to provide a step variable fence for positioning the pilot holes with respect to the working edge of the work piece. There is a centering notch for aligning the boring guide with a centerline drawn on the workpiece.

Abstract: A pocket joint cutter system for forming a pocket cut and fastener bore into a workpiece. The pocket cut and fastener bore receives a fastener such as a self-tapping screw which passes through the bore and into a second workpiece for forming a Joint between the two workpieces. The head of the fastener is held within the pocket cut in order to secure the joint. In one preferred form of the present invention, a workpiece system secures the workpiece in a predetermined position and forms the pocket cut and fastener bore into the workpiece. This preferred embodiment further comprises a bench-mounting system coupled to the workpiece system for securing the system to a bench. Using this embodiment of the present invention, the system can be mounted to a bench, and the workpiece can be brought to the system and held in position while the user forms the pocket cut and fastener bore.

Abstract: A displacement detector which supports either the main scale or the grid to move in a direction perpendicularly intersecting the relative movement direction of the spindle, and which has a spring for pushing one of the main scale and grid toward the other, protrusions for maintaining a predetermined clearance between the urged one of the main scale and grid and the other, and a clearance limiting device for limiting a displacement of the urged one of the main scale and grid from the other to a limited clearance distance to prevent a loss of measuring continuity.

Abstract: A gauge for measuring or checking the dimensions of a weld, as well as many workpiece dimensions. The gauge comprises a pair of generally rectangular plates which are slidably secured together. One plate has a removed corner protion and the two plates are provided with a plurality of scales.

Abstract: A portable measuring device includes a template for measuring the width of an associated cutter tip. A plurality of spaced width indicator marks of different sizes are provided on the template member. A magnifying member is provided for magnifying at least one of the plurality of width marks. A housing member is provided for slidably supporting the magnifying member on the template member.
