The measuring unit includes a transmitter and a measuring processor in communication with the transmitter. The measuring unit includes a first retractable tape measure having a first variable resistance wire and a sensor, the measuring processor having programming for determining first distance data and for transmitting that data.

Abstract: It is a miter saw table that has adjustable measuring tapes. The tape sections can be calibrated so that the zero point on the tape is always set at the outer surface of the blade. This is done by using slidable wings that can be secured to a base. The wings a readjusted until the built-in tapes match a control tape. Once the wings are set, cuts can be made quickly by either setting a stop at the precise distance needed, or by sliding the board under the blade until the end of the board aligns with the desired measurement. The board can then be accurately cut without having to measure and mark the board first. Moreover, if the blade is changed during the course of work. The measuring system can be quickly re-calibrated to the thickness of the new blade and cuts can immediately be resumed.

Abstract: An improved hollow grinder bevel angle control wherein a height-attitude coupling mechanism links the height and attitude motions of an adjustable tool-rest, and a scale on a stationary portion of the grinder cooperates with a pointer on the height-attitude coupling mechanism to indicate a relationship between bevel angle and grinding wheel radius. The coupling mechanism is implemented with a linkage mechanism that provides a wide range of tool-rest adjustment, subject to the height-attitude relationship defined by the linkage. The pointer is mounted for rotation with the linkage mechanism about its fixed pivot point, and is user-adjustable so that a dimension from the fixed pivot point to the tip of the pointer coincides with the radius of the grinder wheel. The bevel angle scale is stationary with respect to movement of the linkage mechanism, and arranged so that the tip of the pointer sweeps across the scale as the linkage mechanism is adjusted through its full range of movement.

Abstract: The combination saw guide and gauge permits the use of a powered saw such as a circular, jig, or reciprocating saw to make cuts with precision presently requiring a table saw with a circular saw blade. The combination saw guide and gauge comprises a scale with at least one uppeer jaw that, in combination with at least one screw, serves to clamp the device to the base of the powered saw. The scale comprises a base, gradations, and at least one clearance into which a guide member can be inserted. The at least one clearance can be an aperture, a slot, or a groove. The gradations serve as a means of measurement. A purpose served by said means of measurement is enabling setting a width of material to be cut. The device is clampable onto a powered saw base such as is common to, but not restricted to, a circular, jib, or reciprocating saw. An optional guide flange on the scale permits a sawer to grasp and help guide the scale.

Abstract: A method and apparatus for cutting baseboard molding to join two adjacent pieces in an inside comer provides a plate constructed with at least one patterned cutting edge having a contour which conforms to the front face of a baseboard molding. A plate support is adapted to carry the plate, and is in turn itself carried by a clamping apparatus of known type which typically combines features of a vise and a table. The baseboard molding to be cut is carried adjacent to the plate support within the clamping apparatus. Upper and lower angle boards may be used to support the baseboard molding to be cut at a slight angle from perpendicular to the blade making the cut, in a manner that allows a slight bevel to be made in the cut. A cutting device such as a router is then traced along the patterned cutting edge, thereby cutting off an end of a first piece of baseboard molding in a contour which corresponds to the face of a second piece of baseboard molding.

Abstract: An apparatus and method of using a power saw guide for use with a power saw having a sole plate with a fence-following surface spaced a set distance from a sawing plane of the power saw. The power saw guide comprising a long leg and a short leg that are mutually orthogonal legs defining an "L" shape. A permanently attached fence is located along the outer edge of each leg defining a sole-sliding edge to guide the fence-following surface of the saw. Each fence is located on opposite surfaces of the guide Opposite the sole-sliding edge of the fence, is a plank-contact edge that makes contact with plank edge and ensures the cutting of the plank is done perpendicular to the length. An apron gusset extends beyond the intersection of the legs in both mutually orthogonal directions. The apron gusset is aligned with the plank-contact edges of the fences. Since the set distance for each power saw is different, the apron gusset initially has a length that exceeds the set distance.

When the edge of a work piece mounted on the table of the milling machine is slowly advanced by a machinist to contact the rotating end member, the flat thereon produces an audible clicking sound each revolution of the spindle. Moreover, upon contact, the flat on the rotating working end member causes it to vibrate radially thereby enhancing the sidewise jump thereof and making it easier for the jump to be observed by the machinist.

Abstract: A log gauge for a chain saw is provided which enables an operator to repeatedly cut approximately equal lengths of firewood logs with only a minimal amount of effort being required to visually measure the logs.
