Abstract
The present invention provides an anti-kickback device suitable for use on circular saws. Kickback occurs when the rotating saw blade engages with a workpiece in a manner which causes the saw blade tojam in the workpiece. The resulting forces can cause the circular saw to fly off the workpiece towards the user. A device, integral with the circular saw footplate, is provided which allows movementof the circular saw in one direction along a guide rail, but which prevents movement of the circular saw relative to the guide rail in a second direction, towards the user. This can be achieved by a device being integrally mounted on the footplate which jams the footplate to the guide rail when the saw moves in the second direction. This jamming of the saw to the guide rail prevents the saw from leaving the guide rail, and leaving the workpiece when the guide rail is clamped to the workpiece, when kickback occurs.
