Abstract: An overhead door mechanism with torsion type counterbalance springs includes a spring adjustment device comprising a housing suitable for attachment to a horizontal shaft and a gearing mechanism that allows angular adjustment of the attached end of the spring relative to the shaft. The gearing mechanism includes a toothed ring gear member adapted for connection to the spring and rotatably mounted in the housing. A threaded worm is also mounted in the housing so that it engages the teeth of the toothed member. Rotation of the threaded worm induces a corresponding rotation of the toothed member. The rotation, when conveyed to one end of a spring that is fixed at its other end causes the spring torsion to be altered without releasing the spring from retention by the adjustment mechanism.

Abstract: A door closer assembly for connection between door and frame members relatively movable between open and closed positions includes a housing having a power screw rotatably mounted therewithin. A follower is mounted on the screw and moves axially along the screw when the screw is rotated. A spring is disposed in the chamber and is compressed by the follower. A handle member is mounted for rotation about a first end of the housing and is connected to the screw for rotation therewith. An indicating member is mounted on the housing for axial movement relative thereto. The indicating member is in engagement with the handle whereby rotation of the handle results in simultaneous axial movement of the follower and the indicator member. The indicator member includes visually observable means for indicating the relative degree of compression of the spring.
