Abstract: A window locking mechanism includes a flanged bracket in which the flange is attached to the window so that the remainder of the bracket protrudes over the window frame. The locking bracket is in a shape to support a disc shaped locking member, loosely supported on a center pin and adapted to wedge between an angled side of the support bracket in the window frame at all times except when the disc is lifted to prevent wedging.

Abstract: A stud for attaching to a door hinge to prevent the removal of the door by the removal of the hinge pins. The security stud has an elongated screw having self-threaded metal threads at the end thereof and wood threads between the metal threads and the head of the screw so that the screw can be threaded into both metal and wooden doors. The head of the screw has dual bevel portions abutting each other in opposite directions; and a stud extending in the opposite direction from the threaded portion of the screw with a slot for a screwdriver tip.
