Abstract
The invention herein named “Magnetized Fence with Stock Feeder for Decked Saws” is in total manifestation a table saw fence or other saw fence magnetized for resistance to lifting, in combination with a stock feeder or powerful spring-loaded workpiece guide mounted directly on said fence. Thus the stock feeder, which advances workpieces over the cutting element of a saw, can be used without its mounting apparatus interfering with lateral travel of the fence. Said invention is comprised of a: 1) saw fence, which guides workpieces, 2) motorized feeder with mounting apparatus, or spring-loaded guide, and 3) mechanisms incorporated for switching the magnetic element.
Claims19
An apparatus, comprising:
- a “T-square” table saw fence having an elongated main body with a proximal end and a distal end and adapted to be secured to a table saw top parallel to a saw blade thereon, the fence having a cam-actuated clamp with a handle on the proximal end for securing the proximal end of the fence to the table saw top, the fence also comprising an ON/OFF switchable magnet actuated by rotation of one magnet with respect to another and mounted within the main body near the distal end, wherein when switched ON the switchable magnet secures the distal end of the fence to the table saw top, the fence further including a mechanism inside the main body configured to switch the switchable magnet ON simultaneous with movement of the handle when actuating the cam-actuated clamp, the mechanism further configured to switch the switchable magnet OFF upon reverse movement of the handle when de-actuating the cam-actuated clamp and releasing the proximal end of the fence from the table saw top;
- and
- wherein the mechanism comprises a spur gear connected to rotate with a core of the switchable magnet and two linear rack gears with teeth in meshing engagement with opposite sides of and for rotating the spur gear, wherein movement of the handle linearly displaces the rack gears in opposite directions via a linkage.
An apparatus, comprising:
- a table saw fence having an elongated main body with a proximal end and a distal end and adapted to be secured to a table saw top parallel to a saw blade thereon, the fence having a locking clamp actuated by a handle on the proximal end for securing the proximal end of the fence to the table saw top, the fence also comprising an ON/OFF switchable magnet actuated by rotation of a core magnet with respect to another magnet and mounted within the main body near the distal end, wherein when switched ON the switchable magnet secures the distal end of the fence to the table saw top, the handle being connected to linkages which linearly displace a pair of rack gears inside the main body of the fence in opposite directions which in turn engage and rotate a spur gear mounted to rotate with the core magnet to switch the magnet ON or OFF simultaneous to movement of the handle.
