This patent covered the addition of a half cock notch to self-cocking revolvers. In operation, it was similar to the "hesitation" mechanisms patented by Ells, Cooper and others.

The patent model was an Allen Wheelock bar hammer revolver with the half cock feature added. No production use of this patent was made.
