The D-handle is not directly connected to the router but is simply affixed to the base plate adjacent the router. The D-handle can be gripped by one hand of the user, and the router handle that sticks out over the transverse edge of the base plate can be gripped by the other hand of the user, and the combined structure can be pushed much like a circular saw with the revolving cutter of the router making an elongated saw cut.

  • Patent number: 5725038
    Abstract: A router baseplate and router table, and a method for accurately mounting the baseplate on a router base and machining table top material to receive the baseplate so that the router may be used suspended upside down in the table top. The router baseplate is a relatively thin plate centered on the router collet that remains attached to the router for free hand use and that is received snugly in a hole in the table top supported by a ledge adjacent to the hole. Two opposed sections of the ledge are omitted so that the router and baseplate can be installed in the table top from the bottom of the table top by tilting the router and baseplate, sliding the baseplate through the openings in the ledge, and then untilting the router and seating the baseplate edge on the ledge. Movement during use in the tabletop is limited by a pin fixed in the baseplate and received in a recess in the ledge.

  • Patent number: 5697413
    Abstract: A method of creating a decorative inlaid floor includes the first step of providing a cutting implement, such as a router, which is operable to machine an inlay recess in a finished wood floor. The next step is to position the router over a section of the floor and move the router in a particular manner so that the desired inlay recesses are machined. The operating and movement step requires that the decorative pattern be predetermined and a control program or NC tape be generated so as to control the drive motors which are associated with each of four slide assemblies. Once the desired inlay recesses are machined into the main floor, the control program is modified by scaling it up to a larger size and is then utilized on a panel of a contrasting material. A typical example would be to select a contrasting wood for the inlay elements. The reprogrammed router is then located over the second material panel and operated so as to machine a larger inlay recess in that second material panel.

  • Patent number: 5694992
    Abstract: A router for engaging a workpiece to be cut has a housing and a motor operable to rotate a drive shaft. A first fence is adjustably secured to the housing, and has a first planar surface oriented substantially parallel to the drive shaft axis. The first fence is adjustable to move the first planar surface toward and away from the drive shaft axis. A second fence is slidably attached to the first fence. The second fence has a second planar surface oriented substantially perpendicular to the drive shaft axis, and has an opening for receiving the bit therethrough. The second fence is slidable to move the second planar surface toward and away from the drive shaft to allow the bit to be plunged through the opening to cut the workpiece. The first and second planer surfaces are sufficiently sized so that either the first or second planer surface can be used as a base for the router with the router center of gravity located directly above the planer surface that is used as the router base.

  • Patent number: 5678965
    Abstract: A device and method are provided for reducing a length of an annular core on which a roll is mounted. If the core extends beyond the end of the roll, the roll is unstable when it is stacked. This device and method will trim the length of the core extending beyond the end of the roll to provide a flat face across the entire end of the roll. A stable stacking arrangement will therefore be ensured. The router includes a collar, a router bit and a transparent disk or plate mounted thereon. The router bit will chip away the portion of the core which extends beyond the end of the roll. A vacuum can be operatively attached to the router in order to remove chips formed by the router bit. The collar on the router will keep the bit spaced from the roll to prevent damage to the roll. This collar and the transparent disk or plate will also aid in guiding the router.

  • Patent number: 5675952
    Abstract: This relates to a workpiece particularly a simulated raised panel door as used on furniture and kitchen cabinets. Such doors are fabricated from a single sheet of core material and have a panel section machined into its face. In certain specific instances it is desired that the corners of the machined panel section be square and at best of very low radii. Because of this corner design it is virtually impossible and definitely time consuming to machine such corners in volume. The problem is solved by using preformed corner plugs inconjunction with a machined core. The core is composed of standard fiberboard material with a panel section machined into its face and plug housings machined into the face of the core at the panel section's proposed square corners. The corner plug is composed of a plastic material formed in part to that of a typical woodworking plug of cylindrical shape and a square inside corner section formed into the face and edge of the plug.

  • Patent number: 5667000
    Abstract: A machine for cutting a cope or kuda in the end of a log has a base member that is secured to a longitudinal side of the log. A support member is attached to the base member. A sleeve is associated with the support member, and an elongate shaft extends longitudinally through an elongate opening through the sleeve. A router is attached to the elongate shaft near one end of the shaft. The sleeve is pivotally mounted to the support member so that the longitudinal axis of the elongate shaft that extends through the sleeve can be set to any desired, acute angle of up to 90 degrees with the longitudinal axis of the log. The shaft can be moved longitudinally back and forth through the sleeve, and the shaft can also rotate about its longitudinal axis. This allows the router to be moved back and forth over the end of the log to cut an incurved, cylindrical cut into the end of the log, with the axis of the cylindrical cut being set at any desired degree of slope relative to the longitudinal axis of the log.
