Abstract
Abstract A security file having a cabinet open at the front with mullion means dividing the open front into a series of drawer receiving pigeonhole compartments. Spaced outer and inner shells form the cabinet, the inner shell including a duplex walled entryresistant shell comprising an outer sheet of aluminum and an inner sheet of abrasive steel. Insulation material fills the space between the outer and inner shells where an insulated security file is desired. Drawers are slidably located in the pigeonholes and a gang-lock bolt mechanism which extends through the drawer fronts and mullion means is operated by a handle of the main locking mechanism. The gang-lock mechanism includes dual upper and lower bolts located at the corners of each drawer and tied together by tie straps. A bolt strap is rigidly connected at one end to each tie strap and pivotally connected at its other end to a rotatable cam plate. A plunger operated bolt is fixed to the lower tie strap in the upper or main locking drawer and operates a plunger in the next-adjacent mullion means. Each such plunger contacts the upper end of a gang-lock control rod, the lower end of which contacts the plunger in the next-lower mullion means. Horizontally disposed side bolts are pivotally connected by actuating arms to diametrically opposite points on a cam disc in each drawer front. Detents are provided which prevent locking of any drawer unless the same is fully closed, and release means is provided for releasing said detent means when the drawer is fully closed. An anti-wedge plate is provided in each drawer front and protective angles are welded thereto in positions to permit locking of the bolts in each drawer to pass therethrough. A protective cover is provided for a locking bar bolt which connects the lower tie strap in the main locking drawer with the cam plate. Protective device are provided to impede drilling of the ends of lock bolts and the lower ends of the lowermost control rod of the gang-lock. Protective devices and anti-wedge means are provided in various areas of the mechanism to impede access to or actuation of the mechanism if attacked by externally applied force.
