Abstract
A dashpot type door closer having an internal mechanism which will latch the door in an open position when the door is opened a sufficient distance, and which will release the door from a latched open position when the door is moved slightly more in the opening direction. A piston rod having a latching member extends through the internal mechanism and the latching member is pivoted between latched and unlatched positions by the internal mechanism.
