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.
Claims20
In a saw grinder comprising a carriage, a mounting assembly, a dividing block and a power-driven grinding wheel, the improvement comprising:
- a front wear plate assembly having a front slide plate and a front fixed plate, the front fixed plate fixed to the dividing block and containing a slot to slidably receive the front slide plate for allowing relative movement between the front fixed plate and the front slide plate, and the front slide plate substantially fixed relative to a peripheral edge of a saw blade when the saw grinder is in use;
- a back wear plate assembly having a back slide plate and a back fixed plate, the back fixed plate fixed to the mounting assembly and containing a slot to slidably receive the back slide plate for allowing relative movement between the back fixed plate and the back slide plate, and the back slide plate substantially fixed relative to a peripheral edge of a saw blade when the saw grinder is in use;
- at least one front resilient member for controlling the relative movement between the front fixed plate and the front slide plate;
- and
- at least one back resilient member for controlling the relative movement between the back fixed plate and the back slide plate.
A saw grinder comprising:
- a carriage;
- a mounting assembly supported by the carriage;
- a dividing block supported by the carriage;
- a power-driven grinding wheel mounted on the mounting assembly;
- a front wear plate assembly having at least a first front plate and a second front plate, the front wear plate assembly mounted and assembled so as to allow relative movement between the first and second front plates, the first front plate substantially fixed relative to a saw blade when the saw grinder is in use, and the second front plate fixed relative to the carriage;
- and
- a back wear plate assembly having at least a first back plate and a second back plate, the back wear plate assembly mounted and assembled so as to allow relative movement between the first and second back plates, the first back plate substantially fixed relative to a saw blade when the saw grinder is in use, and the second back plate fixed relative to the carriage.
A method for using a saw grinder with improved wear plates, the method comprising:
- providing a saw grinder having (i) a carriage, (ii) a mounting assembly supported by the carriage, (iii) a dividing block supported by the carriage, (iv) a power-driven grinding wheel mounted on the mounting assembly, (v) a front wear plate assembly having at least a first front plate and a second front plate, the front wear plate assembly mounted and assembled so as to allow relative movement between the first and second front plates, the first front plate substantially fixed relative to a saw blade when the saw grinder is in use, and the second front plate fixed relative to the carriage, and (vi) a back wear plate assembly having at least a first back plate and a second back plate, the back wear plate assembly mounted and assembled so as to allow relative movement between the first and second back plates, the first back plate substantially fixed relative to a saw blade when the saw grinder is in use, and the second back plate fixed relative to the carriage;
- mounting the saw grinder on the saw blade so that the first front plate and the first back plate contact the saw blade to support the saw grinder on the saw blade;
- and
- sliding the second front plate and the second back plate over the first front plate and the first back plate, respectively, as the carriage moves forward and backward.
