The code information is referenced with respect to a blank edge of a side of the key to be cut, and the predetermined sequence of movements being referenced to the detected blank edge position. A key is cut with the key held in the vise jaw with a groove of the key aligned with respect to the vise jaw without needing to align the key with respect to a keyrest.

Abstract: A door lock comprises a driver hub connected to a door lever, a driven hub, a latch lever movable by the driven hub for retracting the lock's bolt to open the lock, and a catch mechanism for selectively connecting the driver hub to the driven hub. The catch mechanism includes an idle position in which the driver hub moves without moving the driven hub and an engaged position in which the driver hub moves the driven hub and thus the lever and the bolt. A state selection mechanism is provided to displace the catch mechanism between its idle and engaged positions. An actuating mechanism, e.g. a solenoid, selectively positions the state selection mechanism such that the latter causes the catch mechanism, when driven by the driver hub, to adopt one of its idle and engaged positions such that the catch mechanism respectively drives, or not, the driven hub.

Abstract: The transponder detector has an antenna for radiating a power signal to an identification transponder of an unidentified type and for reading a response signal characteristic from the transponder. A plurality of power signal and response signal characteristic parameters associated with transponder communication protocols are serially selected and implemented while an analysis of the response signal characteristic is carried out to determine whether the response signal characteristic matches the selected parameters and to produce an identification match signal. The result of the match signal is displayed as text identifying the transponder make and model number on an LCD display, in the case of a hand-held universal transponder detector. The device is particularly useful for confirming the presence and type of transponders embedded in the head of keys.

Abstract: A lock and a key are provided wherein the key is used in conjunction with the lock. The key has a stop bit and a series of coding bits along its shank. The stop bit and each coding bit have a leading edge and a trailing edge to provide coding of the key and to form one side of a groove. The lock has a housing having a key-actuated cogwheel assembly. The cogwheels are registered with a keyhole and are spaced for engagement by the coding bits of the key. A driven cogwheel assembly has a series of cogwheels that mesh with a corresponding key-actuated cogwheel. A lock bolt is projected and retracted between two positions by a lock bolt actuating mechanism responding to position of the stop bit and coding bits.

Abstract: A circular rotating member, having an outer peripheral surface, is rotatably mounted in a ring member. The rotating member includes an elongated central slot and four peripheral slots extending inwardly from the peripheral surface of the rotating member and spaced at 90 degrees from each other. The key of the combination lock extends into the central elongated slot, and a ball bearing is carried in each of the peripheral slots of the rotating member. The inner surface of the ring member is substantially identical to the outer peripheral surface of the rotating member but the inner surface of the ring member includes, additionally, two cut-outs. Thus, when the ring member is driven to rotate at a high speed by an automatic dialer, the ball bearing will be driven by centrifugal force into the cut-out whereby to prevent further rotation of the dial to thereby block the lock.

Abstract: A combination lock is provided having a housing with a lock dial shaft rotatably mounted thereto. A lock bolt is slidably mounted to the housing, and a fence lever is pivotally coupled to the lock bolt. A tension spring constantly urges the fence lever into an operative, lock bolt displacing position thereof. An assembly of gated tumbler wheels is rotatable by the lock dial shaft and a slotted disc is mounted on a tumbler wheels assembly. The fence lever is adapted to close against the gated tumbler wheels when in alignment and thereby enabling the displacement of the lock bolt by the fence lever. A displaceable spring cam plate is coupled to a cam disc associated with the slotted disc so that, on every revolution of the cam disc, the plate becomes displaced a short distance. A second spring coupled between the fence lever and the cam plate is effective in the non-displaced position of the plate to restrain the pivoted movement of the fence lever under the tension of its spring.

Abstract: A locking system is provided for doors with a bolt unit installed on the inside and a control unit installed on the outside of the door. The bolt unit has a casing enclosing a bolt displaceable between a projected, locking position and a withdrawn, unlocking position. A solenoid device has an armature being displaceable between electromagnetically induced attracted and repelled positions. Linkage means are coupled between the armature and the bolt to drive the bolt between the unlocking and locking positions, respectively. A pass code may be entered into the control unit, and in response, a solenoid may be actuated by a current pulse into the unlocked position of the bolt. In addition, a reverse current pulse actuates the solenoid into a locked position of the bolt.

Abstract: An electrically operated locking system for doors and the like has an electrically operated locking device installed inside the door. A control device installed outside the door is operatively connected with the locking device. A sensor detects the position of the door with respect to the door mounting by a light activated means electrically coupled to the locking device such that when darkness is sensed, the locking device is activatable to operate the locking unit. When light is sensed, however, the locking device is nonactivatable.

Abstract: A key cutting machine having manual and automatic modes of operation includes a shaft, a pivotal carriage on the shaft with clamps for a master key and a blank key, the master key facing a tracer bar and the blank key facing a cutter. A spring acts between the carriage and the shaft and a latch system, operated by a trigger selectively locks the carriage and shaft for common rotation for a manual key cutting operation in which the force of the spring is disengaged from the carriage or unlocks the carriage and shaft so that the carriage is urged by the spring to bring the master key into contact with the tracer bar and the blank key into contact with the cutting. A drive system axially moves the shaft and the carriage therewith past the tracer bar and the cutter in the automatic key cutting operation.

Abstract: The push-button lock arrangement includes a permutation chamber, and, in accordance with the invention, the combination of the permutation chamber can be changed without dismantling the lock arrangement and without the use of special tools. A cam, which is rotated by a simple screwdriver, activates the end of the lock-out slide of the permutation chamber to put the permutation chamber in its reset mode. The lock arrangement also includes a rotating stop member and a stationary stopper. The rotating stop member is connected to the outside door knob so that the rotation of the outside door knob is constrained to a predetermined angle of rotation.

Abstract: A permutation lock chamber has a chamber shaft extending therethrough which is held against rotation when the chamber is in a locked condition and which is rotatable when the chamber is in an unlocked condition. The chamber shaft is connected to the shaft of an outer door handle through a clutch. When the chamber is in its unlock condition and the outer door handle is rotated, the clutch engages and the chamber shaft rotates with the outer door handle shaft. When the chamber is in its locked condition and the outer door handle is rotated, the clutch slips to permit rotation of the outer door handle shaft without rotation of the chamber shaft.
