ABSTRACT:
Surface mounted apparatus for closing a door that is hinged along a side thereof includes a commercially available spring powered closer unit that is mounted within a heavy duty outer housing secured directly on the door. A pivoted linkage is connected between the closer unit and a bracket secured directly on a door jamb. The linkage is constructed of heavy duty arms and pivot pins are mounted permanently as by welding. A stub shaft on the linkage extends through a tiltable bearing unit into the outer housing to engage the output shaft of the closer unit. Extensive use is made of tamper resistant fasteners to secure elements together and to mount the outer housing and the bracket.
