Abstract:
A saw grinder having improved wear plates for allowing the saw grinder carriage to move without having to overcome the resistance caused by contact of the saw grinder wear plates with the peripheral edge of a saw blade. The wear plates form two separate wear plate assemblies, each having a slide plate and fixed plate containing a slot for slidably receiving the respective slide plate. This configuration permits the entire saw grinder, except the slide plates, to easily move in the direction of the force applied to the grinder carriage by allowing the slide plates to fixedly engage the peripheral edge of the saw while the fixed plates remain fixed to the saw grinder carriage and thus move therewith. Resilient members can be used to control the relative movement between the fixed plates and slide plates.
