Ox-Yoke Key.
Description:
Patent for an ox-yoke key that holds the bows in place. The key makes movement easy because of a swinging plate. "By this arrangement the plate may be swung so as to move the key away from the bow, and so as to move it toward the same; and in operation of advancing and retracting the key, the plate swings in the manner described abode" (lines 20-25).
