This gauge with three pins is used to set a lead (one raker tip higher then the other) on the rakers. The right and left pin can be used to set the rakers on both ends of the saw with the same tool and without reversing the saw. At least that is what the patent description says.

See:

It was common practice to set the lead so that raker tips closer to each end of the saw were longer. On a large log this would tend to pull cuttings better from the center of the log toward the ends of the saw and out of the kerf.
