Safety Shaft Coupling.
Patent for a new and improved coupling for thills. This design consists in "the combination of the side plates having recesses in their upper edges, the coupling-plates pivoted to the side plates and having recesses in their lower edges registering with the recesses in the side plates, the free ends of the coupling-plates forming detents, the thill having trunnions resting in the registered recesses, and the spring-actuated locking-bar engaging the detents of the coupling-plates" (lines 110-119).
