Claims12
In a saw tooth grinding machine, means for mounting a saw with a tooth of the saw occupying a grinding station in the machine,
- first and second power-driven grinding wheel means, each including a grinding wheel, and a mounting for each grinding wheel means, said mountings supporting said grinding wheel means with the grinding wheels thereof disposed in opposed relation on opposite sides of a tooth in said grinding station,
- the mounting for each of said grinding wheel means including means for producing movement of the grinding wheel thereof with that part of the grinding wheel which engages a tooth occupying the grinding station moving in a curved sweep across the side of the tooth which sweep moves toward the tip of the tooth and thence toward the base of the tooth while converging on the side of the tooth.
In a grinding machine for grinding the teeth in a circular saw,
- holding means for holding the saw at the eye region thereof with the saw rotatable about its axis,
- an index finger spaced radially from the axis of a saw so held adapted to have a tooth of the saw rest there against thus to position the saw tooth for grinding,
- clamp mechanism for clamping a saw having a tooth thereof so positioned,
- first and second grinding wheel means, each including a grinding wheel, and a mounting for each grinding wheel means, said mountings supporting the said grinding wheel means with the grinding wheels thereof disposed in opposed relation on opposite sides of a tooth so positioned, said grinding wheels being positioned to edge grind opposite sides of the tooth and said mountings for said grinding wheel means including means for producing movement of their grinding wheels simultaneously across opposite side faces of the tooth with each grinding wheel moving in a defined path extending toward the axis of the saw and converging on the plane of the saw.

In a saw tooth grinding machine,
- means for mounting a saw with a tooth of the saw occupying a grinding station in the machine,
- a power-driven grinding wheel means including a grinding wheel and a mounting for said grinding wheel means supporting the grinding wheel means with the grinding wheel thereof adjacent a side of a tooth in said grinding station,
- the mounting for the grinding wheel means including means for producing movement of the grinding wheel thereof with that part of the grinding wheel which engages a tooth occupying the grinding station moving in a curved sweep across the side of the tooth which sweep moves toward the tip of the tooth and then towards the base of the tooth while converging on the side of the tooth.
