Abstract: A high security door lock having a crossbar mounted on a door and a keeper mounted on the door frame. A pin with at least one projection is provided to secure the crossbar to the keeper by inserting the pin through at least one slot in the keeper. A locking channel is provided integral with the keeper and located at an angle to the slot in the keeper. When the pin is inserted into the keeper and rotated, the pin projection seats in the locking channel. A biasing means is provided to coact with the pin to hold the projection in the locking channel and prevent uncoupling of the crossbar from the keeper absent depression and rotation of the pin.

Abstract: A bolt seal for securing hasps on trailer truck doors and/or rail car doors which utilizes a round or oval head bolt which extends through the hasps and upon which a nut is threaded. The nut is threaded onto the bolt until it is tight and then a hollow tube is used to bend the bolt sharply to about 90.degree. just under the nut. Identification number areas are formed at the tail of the bolt and on a flat portion of the bolt adjacent the head. If a thief tries to break the seal by bending the bolt back to its original straight condition, the metallurgy of the bolt is selected so that the bolt breaks off. This indicates that the seal has been tampered with and furthermore, the thief finds that if he tries to turn the nut the round head of the bolt will rotate and since the threads are upset by the bending he will be unable to remove the nut. A modification of the invention utilizes a spin nut which is cylindrical in shape.

Abstract: A security system for double doors which incorporates keeper blocks secured to the doors near their free edges in positions such that they overlap vertically when the doors are closed. The blocks have holes extending vertically therethrough which align when the doors are closed to form a passage for reception of a lock pin assembly having irremovable heads above and below the blocks. The lock pin can only be removed by destroying the pin or the keeper blocks or their supports. The blocks are secured to and shielded by vertically extending reinforcing ribs attached to the doors near their free edges. A pilot hole of a diameter exceeding that of the pin extends through one of the blocks perpendicular to the axis of the pin so that the pin can be cut by means of a drill, allowing the two severed sections of the pin to be moved out of the aligned holes to free the doors.

Abstract: A preferably cylindrical body has a closed bottom bolt opening with an internal spring pressed plunger constantly urged at an angle less than 90.degree. to the bolt opening into interference partially within the bolt opening and retained against such movement by a selectively movable plug within the bolt opening. A bolt preferably having an enlarged head has a recess at an opposite end portion formed generally transversely therein. The bolt end portion is inserted into the body bolt opening displacing the plug further inwardly into the bolt opening and ultimately aligning the bolt end portion recess with the body plunger causing positive interengagement therebetween and permanently preventing withdrawal of the bolt from the body. An annular shoulder of the bolt may engage a body surface at the outer end of the bolt opening during such interengagement to permanently block off the body bolt opening.
