Abstract: A combination lock adapted to simulate a slot-machine including a housing, a rotating wheel assembly, a u-shaped hasp, and a releasing mechanism, said releasing mechanism including an external lever-arm. The rotating wheel assembly is partially within said housing including a plurality of rotatable wheels, each rotatable wheel having a plurality of symbols adapted to simulate the wheels on a slot machine. The u-shaped hasp having a terminating end pivotably connected within the housing and a shackling end adapted to be held within the housing by the releasing mechanism. Said releasing mechanism including a lever-arm having one end extending beyond the housing simulating the actuating arm of a slot machine, and said lever-arm adapted to be actuated when the wheels of the rotatable wheel assembly have been aligned in a pre-determined position, whereby actuation of the lever-arm releases the shackling end of the u-shaped hasp, thereby opening the lock.

Abstract: In accordance with one aspect of the invention, a kicker arm-pawl lock mechanism rotates a number one wheel of a combination lock a predetermined distance to require resetting each number of a combination during lock manipulation. A drive cam-travel arm and bolt lock mechanism assures complete scrambling of the combination by requiring rotation of all wheels prior to bolt extension into a locked position. Another aspect of the invention includes a lock lever and drive cam mechanism which requires opening of the combination lock once a combination has been correctly dialed. A lock lever and pivoting pawl lock mechanism prevents lockout conditions by diverting forces applied to the combination lock bolt to the lock casing rather than the lock lever.

Abstract: A combination lock has a pivoting bolt for engaging and disengaging a hasp. The hasp, which is disengaged from the bolt when the lock is on-combination, may be re-engaged with the bolt, even if the lock is off-combination. A first spring resiliently biases the bolt to an unlocked position. A second spring resiliently restrains movement of the bolt beyond a locked position in order to prevent disengagement of the hasp in response to application of a shock force to the lock.

Abstract: A fast opening, high security combination lock includes a case, a dial connected to a rotatable spindle, and a plurality of rotatable tumblers mounted coaxially therewith. A movable impeller mounted on said spindle is carried by internal projections in the case to engage the tumblers in sequence as the dial is turned through a series of partial clockwise turns to combination characters and returns to a set mark. After setting the tumblers, the impeller engages a driver which, if all of the tumblers have been properly set, retracts a bolt. The impeller is reset to its initial position on the spindle and the tumblers are scattered to secure the lock, by rotating the dial one-half turn anti-clockwise.

Abstract: A lock mechanism having a mechanical combination lock and an electronic lock, wherein the mechanical combination lock serves for effecting a fail safe entry in case of failure of the electronic lock. More specifically, the lock mechanism includes a mechanical combination lock having a bolt-retracting linkage which is tripped by inward movement of a dial into a first operative relationship with a driver on the drive spindle. An electronic latch prevents bolt retraction by this bolt-retracting linkage when in the first operative positive until the electronic latch has been operated. However, when the tumblers of the lock have been aligned and a gate bar enters the tumblers, the bolt-retraction linkage is caused to assume a second operative relationship with the driver so as to permit bolt retraction despite the latching effect of the electronic lock.

Abstract: A fence lever control device for a combination lock provides a pivoted plate having an arm positioning a spring to normally bias the fence lever of the lock in a position out of engagement with the fence lever operating cam wheel, with an actuator roller mounted to the cam wheel which engages a follower surface on the pivoted plate once on each complete revolution of the cam wheel in a given direction in response to similar rotation of the dial shaft to which the cam wheel is mounted to thereby shift the pivoted plate and its associated spring mounting arm in an over center fashion to place the spring in a position to bias the fence lever toward the cam wheel, movement of the fence lever into engagement with the cam wheel being prevented by engagement between the fence member and the tumbler wheel assemblies when the wheel assemblies are not oriented in a predetermined relationship.

Abstract: The invention relates to the technical field of combination locks, and in particular to a combination lock of the type having a plurality of combination dials which, once angularly positioned, enable a manually turnable driver element to cause translation of a bolt element by a means of a stud engageable with said combination dials.Provision is made for said stud to be rotatable coaxially with said dials and oscillably movable radially thereto. Further, said dials are defined by a ring which is split by a cut and clamped, by elastic deformation, onto a smooth surface of a hub.

Abstract: A keyless lock which eliminates the requirement for visual contact with the lock to effect disengagement thereof. A series of push buttons are operated by depressing each push button the proper number of times according to a predetermined numerical code. The push button increment ratchet wheels having slots therein. When the slots are in proper alignment with lock releasing pins, the lock can be opened.

Abstract: A live bolt lock mechanism for a safe door uses a rotatable idler 15 in a middle region of the door. A plurality of live bolts 20 spaced around the door each has a connecting rod 19 joined to the idler 15 at crank locations for operating the live bolts. A handle 25 is mounted between the idler and the opening edge of the door, and a combination lock 30 is mounted beside the idler. An actuator 27 rotated by the handle moves an actuator link 31 connected to the idler for rotating the idler when the handle turns. A lock link 50 mounted on the idler and extending toward the combination lock 30 has a projection disposed adjacent the combination lock to block the lock link and idler from movement unless a combination for the lock is fulfilled.

Abstract: A combination lock having a plurality of rotatable tumblers, a knob for positioning the tumblers, a bolt, a bolt cam for operating the bolt to unlock the lock upon proper positioning of the rotatable tumblers by proper clockwise and counter-clockwise rotation of the knob, and locking means for preventing said bolt cam from operating the bolt prior to proper positioning of the rotatable tumblers. According to a preferred embodiment the locking means includes a floating pin unconnected to any structure but moveable within the lock structure between positions preventing and permitting movement of the bolt cam and the knob is longitudinally moveable to engage the bolt cam for operation of the bolt.

Abstract: An improved combination lock mechanism including a dial adapted for removable securement thereto. Mechanically connecting a conventional wheel pack and drive cam combination to a lock cam is a locking lever pivotally secured at a point intermediate the opposite ends thereof to said lock cam, said lever having a first end adapted for engagement by said drive cam and wheel pack and a second end conforming to at least a portion of the peripheral geometry of said wheel pack. Finally, there is included a relock plate and means for biasing said relock plate against lock bolt connective members. Fence members are formed on said relock plate and spaced apart a distance slightly less than the distance between the ends of said connective members when said connective members are in an extended position. Thus, the urging of said relock plate against said extended members upraises said fence members to a position proximate the ends of said extended connective members whereby to inhibit the retraction of the locking bolts.

Abstract: A replacement housing and plug adapted to substitute a key-operated housing, plug and tumblers in an existing tumbler lock without extensive modification of an existing installation in a door, thereby reducing the possibility of mechanical picking of the tumblers which are thereby eliminated. The combination tumblers are disposed for rotation about an axis corresponding to the axis of the substituted plug, and a resiliently urged locking bar is positioned above the tumblers to drop into tumbler engaging position when the proper combination has been obtained, thereby interconnecting a dial member with a lock opening means for transmitted motion from the former to the latter.
