The under surface of the segment O is escalloped,
in such a manner as to form curved recesses, c' c', int'o which the springwvheel D is forced by the action of the spring d', thereby retarding the motion of the door, Or stopping itat any desired point.
The wheel D is pivoted between the jaws of afvertical rod, e', which slides in the recess e, formed in the case E,',which is secured to the door by three screws, o a.' a, and a staple, b.
A shoulder is formed onthe lower end of the rod e, as a bearing, against which the end of the spring d operates.
This device may be fixed at the top or bottom of a door, and is rather ornamental than otherwise.
