spring 10 against the member 9 maybe wring-pressed member 9 moves in a path which will cause it to encounter the stop 4: laterally and the tension of the spring 10 should be suflicient (when the sto is in action) to hold the arm 3 in the position in her 9 is back of the 'stop shoulder 4; that is to say, sutiicient to prevent the closer spring (not shown) from restoring the arm 3 to its normal position in. which the door is closed. \Vhen it is desired toclose the mented.-\'iz., by a pressure against the door, thus causing the spring member 9 to be pressed back until it clears the stop 4, wrhereupon the closer mechanism restores the arm 3 to its normal door closingposition. Obviously, by this a-rrangementthe stop 4 maybe adapted to either a right or deft handdoor. and may be so set as to the door ajar at any desired=positionl It is obvious that this stop mechanism may be readily applied at minimum cost; almost any form of door close'r 'and may be put into action or out of action at amoments notice either by releasing the tension against the member 9 or by shifting the stop shoulder l to surh aposition that it will not be encountered by the member 9 at any angle to which the door is opened.
