Appl. No.:

09/850217

Inventors:

William J. Ryan - Arlington Heights IL
Carl C. Carlson - Vernon Hills IL

Assignee:

S-B Power Tool Company - Chicago IL

International Classification:

B27C 100

US Classification:

1441545, 14413695, 409182, 409187, 408 16

Abstract:

A plunge-type router is disclosed which has a base and a head assembly that is vertically adjustable by an adjusting mechanism. The plunge router includes an electronic control system with a digital display and control functionality that enables the router to accurately determine a baseline or zero position for a router bit installed in the router and permits the user to input a depth of cut value or other predetermined command. The control system then automatically causes the motorized adjusting mechanism to go to the appropriate position. The electronic control system enables the storage of multiple depth settings as well as multiple step or macro operations. In this regard, macros may be run to provide incremental cutting necessary for performing multiple passes to achieve a relatively deep depth of cut.

US Classification:

1441341, 1442865, 1441361

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.
