Abstract: A view limiting enclosure and assembly for dial combination locks with a dome cover(9): which completely covers a dial combination lock(1): dial turning knob(3): and dial except for a dial viewing hole(10): to view the dial graduations as they go by a partly transparent L shaped cover(6): which covers the dial inside the dome cover so that only 3 or 4 dial graduations are seen at one time and all but one dial graduation mark looks the same. A rope pulling hole(11): in the side of the dome cover contains a rope(2): that goes around the dial turning knob and is used to turn the dial by pulling on one end or the other end of the rope slowly and counting one dial graduation at a time until the correct combination is reach to open lock. It takes one minute to open sober, very hard if not impossible, to open if you are drunk.

Abstract: A disk shaped element has a plurality of tactile sensed position indicators arranged along its' circumference. Each position indicator consists of a straight bar terminated at one end with a rod having a diameter greater than the thickness of the corresponding bar. Each bar extends outwardly from the circumference of the disk, and each rod extends outwardly from the circumference a distance greater than the corresponding bar. Each position indicator on the dial is oriented analogous to an hour hand position on a clock, with the rod providing a reference for the base of the hand.

Abstract: A lid is secured to the base of a key box device that defines an enclosed compartment for securing a spare key. The lid carries push-buttons and a knob for locking the lid to the base. The surface of the lid is generally flush with the plane of the base edges thereby eliminating locations for prying the lid from the base. A flanged portion in the lid and corresponding recessed portion in the base sidewalls provide gripping sidewalls to facilitate handling of the lid.

Abstract: A system for introducing fresh air to a locked vault which is integral to the door of the vault. A fan provides motive force to the air which flows principally through passages in, or created with, existing components in the door. A food/water passage may be furnished by providing the door wheel spindle as a hollow, rather than a solid, tube.

Abstract: A combination lock of the type having a hollow base (1) containing a central plunger (12) guided for both rotational and slidable movement therein, the base (11) having a plurality of base notches (26) selectively engageable by lock plungers (31) carried by the central plunger (12) for axial movement, each lock plunger (31) having a portion capable of being contained within a respective notch (26) to thereby inhibit rotation, each lock plunger (31) also having a notch (33) arranged, when correctly positioned, to permit rotation of the central plunger (12), and a selection knob (42) which is rotational and slidable with respect to the central plunger (12) and which has a push pin (43) operable to depress selected ones of the lock plungers (31), the central knob (42) obscuring the lock plungers (31) such that it is not apparent which of the lock plungers are the selected ones for a combination.

Abstract: A bushing 10 for a safe door combination lock supports a spindle 20 extending through inner and outer door walls 13 and 12 separated by a space filled with insulation. A stub 15 secured in a hole 17 in the inner wall 13 by a rotational rivet 16 has an axial bore hole and a machined periphery for receiving components of the combination lock. A thin walled tube 11 extends through the bore hole in stub 15 and through the space between the inner and outer walls. An outer end of tube 11 is flared against an outer surface of outer wall 12 and an inner end of tube 11 is flared against an inner end of stub 15. Tube 11 then receives spindle 20 for the combination lock without providing a large heat conductor through the interior of the safe. Also, if tube 11 and spindle 20 are driven into the interior of the safe with a punch, stub 15 retains the tumbler wheels of the combination lock to keep the lock secure.
