Abstract

A system for setting and sharpening teeth of a saw blade includes a frame, a sharpening assembly and a setting assembly. A block affixed to the frame defines at least in part a blade path. The sharpening assembly is configured to sharpen a first tooth of the saw blade in a first position of the blade path. The setting assembly configured to set the first tooth of the saw blade in a second position of the blade path, wherein the blade path is defined through the sharpening assembly and the setting assembly. An advancement assembly is configured to move the saw blade along the blade path in an advancement direction to advance teeth of the saw blade into and out of the first position, and into and out of the second position.

Dependent claims

A system for setting and sharpening teeth of a saw blade comprising:

a frame having a first block affixed thereto, the first block defining at least in part a blade path;
a grinding wheel, a motor operably coupled to drive the grinding wheel, the grinding wheel configured to sharpen a first tooth of the saw blade in a first position of the blade path;
an actuator operably coupled to drive at least one tooth setting clamp to set the first tooth of the saw blade in a second position of the blade path, wherein the blade path is defined through the first position and the second position;
and
a lever pivotably connected to the frame, and a push pawl pivotably connected to the lever, the lever and the push pawl configured to move the saw blade along the blade path in an advancement direction to advance teeth of the saw blade into and out of the first position, and into and out of the second position;
wherein the at least one tooth setting clamp further comprises
a first tooth setting clamp configured to clamp the first tooth and set a first lateral position of the first tooth in the first position, and
a second tooth setting clamp configured to clamp a second tooth of the saw blade to set a second lateral position of the second tooth of the saw blade concurrently with the setting of the first lateral position;
wherein the second set position is in an opposite direction relative to the first set position from a blade path plane defined centrally along the blade path in the advancement direction;
wherein the frame supports the motor and the actuator;
and
the system further comprising
a second block positioned adjacent to a second side of the blade path plane;
and
wherein the first block includes the first tooth setting clamp and is disposed adjacent to a first side of the blade path, and
wherein the system further includes a third block positioned adjacent to the second side of the blade path plane, the third block including the second tooth setting clamp.
