  • Publication number: 20100089496
    Abstract: A router accessory for attachment to the router base allows a plunging router to cut a mortice in a workpiece. The baseplate accessory has a central aperture for the bit and width dividing fingers projecting from the base capable of straddling the workpiece and upon rotation to abut the sides of the workpiece and aim the bit half way between the workpiece sides. A router modified with a built-in baseplate with this capability is described. A dedicated router with the same feature which allows deep plunging such as for mortice locks is described.

  • Publication number: 20090056833
    Abstract: A router table comprises a table top, a bit mount, and a drive train. The bit mount is configured to hold a router bit such that the router bit extends from the table top defining a bit axis. The drive train is positioned under the table top and is operably connected between the bit mount and a drive coupling. The drive coupling is configured to engage a driven member, with the drive coupling defining a drive axis that is not coaxial with the bit axis. The driven member may be provided by a drive bit on a portable router secured to the table top. Operation of the portable router results in rotation of the driven member. Rotation of the driven member and associated drive coupling operates the drive train and results in rotation of the bit mount and associated router bit.

  • Patent number: 6585018
    Abstract: First and second guide plates are engaged for linear sliding between them by a channel and rib engagement system. A grooving tool is carried by the plate associated with the rib, and the rib is in axial alignment with the tool head, such that the tool head can lead the rib. When a groove is being cut into a workpiece, the rib can follow the tool head into the cut groove to extend the range of the guide. Ribs of different size can be selected to coordinate with the tool and groove width. Filler strips similarly coordinate the channel width. An alternate or supplemental guide system joins the first plate to a series of accordion style hinged and foldable plates. These plates guide the first plate in linear movement as they fold or unfold.

  • Patent number: 6510878
    Abstract: An attachable baseplate for a highspeed router which can be used with router in an upright handheld position, or in an inverted position with router suspended by same baseplate in a router table. Front edge of baseplate has cutout portion for sliding engagement and containment of a right and a left incrementally marked alignment indicator. When secured to baseplate in a predetermined position indicators show actual diameter margins of the installed cutting tool. This simplifies and makes precise the alignment of the cutting tool to the layout line of the workpiece and allowing measuring capabilities when enlarging the existing cut without the necessity of changing cutting tool. Alignment and measuring capabilities perform equally in the handheld or suspended router table mode.

  • Patent number: 6382276
    Abstract: The invention relates to a slotless router base plate used for mounting routers by a majority of manufacturers to a router table. A router is attached to a baseplate, and then this router-baseplate assembly is attached to a router table. Numerous hole grouping patterns are provided to accommodate various routers, eliminating the need for users of the baseplate to create holes for specific router models themselves. Slots in the router baseplate are avoided to provide for greater strength and stability in the mounting. An alternative embodiment includes providing a labeling for the hole groups. The router baseplate may be round, but alternative shapes are provided, including providing the hole pattern directly in the router table.
