Abstract: A flush mount latch assembly including a housing having sidewalls and endwalls that define a chamber and an open face defined by front surfaces of the side and endwalls and opening into the chamber. Pivotally mounted along a pivot axis between the sidewalls is a face plate handle that covers the open face. The face plate includes a push portion disposed on one side of the pivot axis and a pull portion disposed on an opposite side thereof. In response to pivotal movement of the face plate the push portion enters the chamber and the pull portion pivots away from the open face. Also included on the face plate is a plate surface pivotably movable within the chamber during pivotal movement of the face plate. A bolt is mounted for reciprocating linear movement within the chamber and projects through a bolt passage defined in one of the housing sidewalls.
Abstract: A cylinder lock with a shell defining a plug cavity, a plurality of locking shell tumblerways, and a control shell tumblerway. A plug is rotatable within the plug cavity and defines a plurality of locking plug tumblerways alignable with the locking shell tumblerways, a control plug tumblerway alignable with the control shell tumblerway and a keyway for receiving keys. Positioned within each of the locking plug tumblerways is a locking tumbler that is biased into an active position wherein it projects into one of the locking shell tumblerways and movable into an inactive position out of the tumblerway by a proper key in the keyway. The locking tumblers prevent rotation of the plug when in their active positions and allow rotation thereof when in their inactive positions. Retained by the control plug tumblerway is a control tumbler biased in a latched position and movable into a release position by a control key in the keyway.
Abstract: The invention is a lockable electrical switch including a cylindrical plug mounted within a shell for rotary movement between locked and unlocked positions and for axial movement between active and inactive positions, the plug defining a keyway and a plurality of tumblerways intersecting therewith. Residing in the tumblerways are tumblers that operatively engage the shell and the plug so as to prevent relative rotation therebetween in the absence of a proper key in the keyway. A movable contact is mounted for movement with the plug and a stationary contact is shaped and arranged so as to be engaged by the movable contact with the plug in both its unlocked and active positions but to be disengaged therefrom with the plug in either of its locked or inactive positions. Closure of the switch by engagement of the contacts requires the use of a key to rotate the plug into an unlocked position.
Abstract: Disclosed is a cylinder lock with an annular housing defining a cavity that retains a lock core formed by a cylindrical plug within an annular shell having an internal longitudinally directed shell spline. The plug is retained within the annular shell in a locked position and is rotatable therein in one direction to an open position and in the opposite direction to a release position. A plurality of locking tumblers are retained by the plug and engage the shell spline to prevent rotation of the plug from its locked position unless the locking tumblers are withdrawn from the shell spline by a properly bitted key inserted into a keyway defined by the plug. Coupled to the plug is an actuator member that moves a locking member between latched and unlatched positions in response to rotation of the plug.
Abstract: A cylinder lock with a hollow cylindrical shell that defines a plurality of shell tumblerways and is longitudinally movable in a shell cavity defined by a housing. Received by the hollow shell is a plug that defines a keyway for receiving a proper key and a plurality of plug tumblerways aligned with the shell tumblerways. The plug is rotatable within the shell but is longitudinally restrained therein. A plurality of locking tumblers are accommodated by the aligned shell and plug tumblerways and are movable from biased locked positions into open positions by a proper key in the keyway. Also responsive to a proper key is a control tumbler that can be moved out of a biased, latched position into a release position. The control tumbler obstructs longitudinal withdrawal of the shell from the shell cavity when in its latched position and permits withdrawal when in its release position.
Abstract: A security apparatus including a cylinder lock with an actuator plug rotatably mounted within a hollow cylindrical housing. Retained by the actuator plug are a plurality of locking wafers that are spring biased into a locking spline formed in the inner surface of the housing so as to retain the plug in a locked station. Also retained by the plug is a directional wafer, spring biased in a primary position wherein it permits both clockwise and counterclockwise rotation of the plug from the locked station and movable into either intermediate or auxiliary positions wherein it allows clockwise rotation but prevents counterclockwise rotation of the plug. A control key is bitted so as to pull the locking wafers into shear positions and to draw the directional wafer into its intermediate position permitting rotation of the plug to a second station. Also defined by the housing is a tumbler stop that establishes a third operational station located between the locked station and the second station.
Abstract: Disclosed is a lock comprising a housing and a shell movable therein between a locked position and an unlocked position. Locking apparatus is responsive to a key and releasably restrains the shell in the locked position. Restraining apparatus is responsive to the same key and selectively prevents the removal of the shell from the housing.
Abstract: Disclosed is a key making machine with a sample vise for receiving and retaining a sample key to be duplicated and a blank vise for receiving and retaining a key blank. When the sample key is positioned properly a path of electrical conduction is provided through it. A similar conductive path is established through the key blank when it is properly positioned. A series circuit through the key and blank prevents operation of the machine if the sample key or key blank is not properly positioned. During each cycle of operation, a support table completes one cycle of reciprocating linear motion. Toggles responsive to the motion of the table close the vises shortly after the table begins to move. Positioning towers near the vises support slidably mounted rigid fingers that project toward the vises to aid in the positioning of the key and the blank. Following closure of the vises, the towers respond to the motion of the table and move to a standby position to facilitate the cutting operation.
