ABSTRACT:
A security device for protecting equipment such as typewriters, calculators and the like, comprises a base member having a hole through which the shank of a bolt passes through a mounting body and into the frame or housing of the equipment to be protected, the head of the bolt being held at a seat within the base member. A protective envelope has an end member positioned to be juxtaposed to, and cover, a portion of the base member around the seat to prevent access to the bolt head. The end member has a threaded hole through it communicating with the bolt head, and a lock body having a barrel with a threaded protruding neck which engages the threaded hole, fits within a hollow shank of the protective member. The lock body contains a number of transversely slidable locking blades which resiliently protrude from the barrel to engage spline stops of the shank when in the normal locked position. The lock body can only be unthreaded from the threaded hole when the proper key is inserted into the lock body to force withdrawal of the blades from the locking position, thereby uncovering the bolt head so that access may be had to it. An adjustable bar on a table attaches to the equipment and a locked anchor bolt fastens to the bar.
