Filed:

Jul 13, 1977

Appl. No.:

5/815259

Inventors:

George P. Patriquin - Gardner MA

International Classification:

E05B 2700

US Classification:

70364R

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 first directional wafer, spring biased into a quiescent position wherein it allows counterclockwise rotation of the plug from a locked station but prevents clockwise rotation thereof and movable into an active position wherein it allows either clockwise or counterclockwise rotation of the plug. A second directional wafer is spring biased in a primary position wherein it permits both clockwise and counterclockwise rotation of the plug from the locked station and movable into an intermediate position wherein it allows clockwise rotation but prevents counterclockwise rotation of the plug. A first control key is bitted so as to pull the locking wafers to shear positions out of the locking spline while leaving the first and second directional wafers in their quiescent and primary positions, respectively, A second control key is bitted so as to pull the locking wafers into shear positions and draw the first and second directional wafers into their active and intermediate positions, respectively. Finally, a master key is bitted so as to draw the locking wafers into shear positions, pull the first directional wafer into its active position and leave the second directional wafer in its primary 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. The tumbler stop is engaged by the directional wafer when in its auxiliary position so as to prevent clockwise rotation of the actuator plug beyond the third station but it is not engaged with the directional wafer in either of its primary or intermediate positions which allow continued clockwise rotation of the plug to the second station.

International Classification:

E05B 2700

US Classification:

70369

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.

International Classification:

B23C 116

US Classification:

90 1305

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.

US Classification:

70 90

Abstract:

Disclosed is a lock comprising a housing and a shell movable therein between a locked position and an unlocked position.

Appl. No.:

Inventors:

George P. Patriquin - Gardner MA

Assignee:

Hudson Lock, Inc. - Hudson MA

International Classification:

E05B 1514
E05B 2902

US Classification:

70369

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. Also retained by the plug and engaging the shell spline with the plug in its locked position is a release tumbler shaped and arranged to permit rotation of the plug to its open position but to prevent rotation to its release position. The release tumbler also can be withdrawn from the shell spline by a properly bitted key so as to allow rotation of the plug to its release position.
