ABSTRACT:
Apparatus for selectively permitting access to the interior of a boiler and selectively closing off access to the interior of the boiler which includes a frame, a support plate, and a hinge. The hinge couples the support plate and the frame and allows pivotal movement of the support plate with respect to the frame. The apparatus also includes a door plate; and apparatus for coupling the support plate to the door plate. In some forms of the invention the apparatus for coupling comprises a plurality of studs fixed to one of the plates in generally parallel spaced relationship. The other of the plates may include a plurality of holes disposed in generally registered relationship to the studs and dimensioned for loose fitting engagement with the studs. The apparatus may also include apparatus for latching the support plate to the frame to prevent pivotal movement thereof with respect to the frame. The apparatus may also include apparatus for urging the door plate away from the support plate toward the frame.
