Patent for a new and improved door check. This design "is to provide a means for preventing the jarring and noise incident to the sudden stoppage of a door or window-blind in closing . . . and to this end it consists of a hinge having one leaf provided with a case or box extending laterally from the back thereof, the said case or box inclosing a spring-actuated bolt which normally projects beyond the point of the leaf, and is arranged to engage with the other leaf of the hinge when the door is closed" (lines 7-19).
