ABSTRACT:
An improvement in R. E. McClellan's U.S. Pat. No. 2,750,901 issued June 19, 1956 to an Insulated Metal Cabinet Construction and its adaptation to lateral or wide shallow drawer insulated filing cabinets. The improvements include: a U-shaped sheet for three panels of the outer shell; reverse flanges at the edges of the outer shell panels; the reduction of welding spots by the use of adhesive in interfitting U-shaped channels between the jamb frame and the outer shell; formation of rail-supporting ribs in the inner shell panels; simplification of the structure and assembly of the jamb frame and its cross members; glass fiber reinforced insulation between the inner and outer shells; the addition of a telescoping slide on the bottom of the drawer, particularly for wide drawers to maintain their alignment and prevent them from becoming askew; simplification of the guide for the follower in the drawer by T-shaped antifriction plastic slides; an adjustable frame of rails and half-partitions for drawers for hanger files; simplification and positive action of the bolt mechanism by reduction of springs and the inclusion of plastic bolts crimped in position on their slides; the adaptation of the bolt mechanism to be operated by either a twist or a pull-type handle on the front of the door; a bell crank and spring interlocking plunger attached to the bolt of a combination lock for spinning its dial and relocking the plunger; a fusible stop for releasing a supplemental door-locking bolt to prevent warping of the door in a fire; mounting of the drawer-locking pawl lever, a bell crank lever and a horizontal sliding plunger rod on a common demountable plate at each drawer; and separate vertically slidable locking bars on opposite sides of the drawers inside the cabinet for locking all the drawers by one key plunger lock on one drawer door, and for preventing the opening of more than one drawer at a time, particularly in wide drawer or lateral drawer-type cabinets to prevent them from tipping over.
