Abstract: A protective cover for electronic equipment automatically expanding by the spring action of a pair of telescoping arms (24) having a cover (48) of resilient material attached between. The arms (24) are positioned contiguous with a pair of bases (20) that are located parallel with each other on the floor on either side of the electronic equipment with a hinged cover enclosure (50) between the ends forming a "U" shape. The arms (24) are connected on the ends by a strut (26) holding the cover (48). Solenoids (58) retain the arms in a tensioned position and when electrically actuated release them. The spring action pivots the arms with its accompanying cover completely enveloping the equipment. A lever (64) arrangement overrides the solenoid action manually releasing the arms. The device is reset by manually rotating and compressing the arms while folding the cover (48) into the enclosure (50). The object is to protect expensive equipment from fire, smoke and water damage if a fire is in the vicinity.

Abstract: A lock type sealed security device or unit for clamping bills accumulated in vending machine validating or other paper currency accumulating devices. The device is locked onto the accumulating device in a position which allows the currency to be accumulated therein. When the currency is desired to be removed, the device is moved into a clamping position and operated to securely clamp the sheaf of paper currency therein. The security device can be unlocked from the validating device only when the currency is clamped and an unclamped sealed security device can be mounted in its place on the validating device. The security device with the currency clamped therein then is removed to a collection area, where the device is unsealed and the currency is unclamped and removed.
