Abstract
Embodiments include a sharpening fixture adapted to mount to the nose of a chainsaw guide bar. When mounted, the operator may direct a force towards the guide bar thereby causing a linear directed actuator to move a sharpening element into engagement with cutters of a saw chain to sharpen a cutting edge of the cutters. In various embodiments, the actuator is biased such that when the force is no longer applied, the actuator pulls the sharpening element out of engagement with the cutters.
Claims31
A saw chain sharpening fixture, comprising:
- an attachment member configured to couple the saw chain sharpening fixture to a nose portion of a guide bar;
- and
- an actuator coupled to the attachment member, wherein the actuator is configured to receive an actuation force at least partially directed toward the nose portion, and in response to the actuation force, linearly move a sharpening element of the saw chain sharpening fixture into contact with one or more cutting links as the one or more cutting links traverse the nose portion.
A method, comprising:
- receiving, by a saw chain sharpening fixture, an actuation force at least partially directed toward a nose portion of a guide bar,
- upon receipt of the actuation force, linearly moving a sharpening element of the saw chain sharpening fixture towards one or more cutting links of a saw chain as the one or more cutting links traverse the nose portion;
- and
- sharpening, by the saw chain sharpening fixture, the one or more cutting links of the saw chain in response to said linearly moving.
1 more element
A system comprising:
- a guide bar;
- and
- a saw chain sharpening attachment configured to couple to a nose portion of the guide bar, wherein the chain sharpening attachment comprises:
- an attachment member configured couple the chain sharpening attachment to the nose portion;
- and
- an actuator coupled to the attachment member, wherein the actuator is configured to receive an actuation force at least partially directed toward the nose portion, and in response to the actuation force, linearly move a sharpening element of the chain sharpening attachment into a cutting radius of a saw chain as it traverses the nose portion.
