Patent for a new and improved door-check. This design "relates to improvements in devices for checking the movements of a door to prevent its forcible contact with a wall or other object, and for automatically fastening it in an open position, so that it will not be accidentally closed. The invention consists of a check or catch plate adapted to be secured to the floor or wall and provided with an inclined track for the passage of a spring-bolt on the door, a transverse projection being arranged vertically at the rear end of said inclined track and formed into a seat for the spring-bolt" (lines 8-20).
