Patent number: 9424701Abstract: A locking device comprises a key that comprises a key power coil and a key data coil and an electronically-actuatable lock comprising a lock power coil and a lock data coil. The key power coil and the lock power coil are coaxial and at least partially overlapping one another when the key engages the lock. The key data coil lies in a first plane and the lock data coil lies in a second plane. The first plane and the second plane are substantially parallel to one another.Type: GrantFiled: June 4, 2014Date of Patent: August 23, 2016Assignee: The Knox CompanyInventors: Dohn J.

Patent number: 8991434Abstract: A lockable pipe cover includes an inner cap and an outer cover which are selectively coupled together for axial rotation. When the cap is locked, the inner cap and the outer cover are free to rotate independently from one another thus rotation of the outer cover will not remove the cap from the pipe. In the unlocked position, the inner cap and the outer cover are coupled for rotation and thus rotation of the outer cover results in rotation of the inner cap.Type: GrantFiled: September 13, 2007Date of Patent: March 31, 2015Assignee: The Knox CompanyInventor: Dohn J.

Patent number: 8683831Abstract: A locking cover plate can be selectively locked in position on a stortz pipe end fitting or can be unlocked and removed for access to the open pipe end. The cover plate includes a sliding plate that is driven laterally outward into a deployed state by rotating a drive bolt. The drive bolt is coupled to the sliding plate through a torque limiting coupling that transfers the rotation of the drive bolt to translating movement of the latch bar with a cam plate. Movement of the sliding plate is indicated through a front of the cover plate such that the user can identify whether the cover plate is locked on a fitting or simply placed on the fitting without the lock engaged.Type: GrantFiled: November 28, 2006Date of Patent: April 1, 2014Assignee: The Knox CompanyInventor: Dohn J.

Publication number: 20100236306Abstract: An electronic lock may include a locking mechanism and a cartridge having a body portion and one or more extension receiving portions that may receive the locking mechanism. The lock may also include a first coil positioned around the cartridge, a core disposed within the cartridge and substantially within the first coil, and a second coil positioned around the cartridge. The second coil may be spaced from the first coil. In addition, a first sliding barrier may be disposed within the cartridge, which barrier may be selectively in communication with the locking mechanism. A control circuit may be included in the lock, which may energize the first and second coils to cause the first sliding barrier to move from a first position magnetically attracted to the core to a second position magnetically attracted to the second coil and thereby allow actuation of the locking mechanism.Type: ApplicationFiled: March 20, 2009Publication date: September 23, 2010Applicant: KNOX Associates, dba Knox CompanyInventors: Dohn J.

Patent number: 7437901Abstract: A locking cap is selectively locked into place within a tubular opening, such as the open end of a standpipe used to charge a building sprinkler system. The locking cap has an expandable sleeve and a spreader member. As a key is turned, the spreader member is drawn into the expandable sleeve which is urged outward. The outward movement of the expandable sleeve increases a frictional component such that the expandable sleeve becomes frictionally locked within the tubular opening. The key has an end design that is complemented by an end of an actuator shaft such that the likelihood of unauthorized removal of the locking cap is reduced.Type: GrantFiled: February 27, 2004Date of Patent: October 21, 2008Assignee: Knox CompanyInventor: Dohn J.

Patent number: 6674080Abstract: An elongated heat detection device identifies heat sources based upon infrared radiation. The device includes a purged and sealed instrumentation chamber and a rugged and shock absorbing case. The case surrounds and protects the chamber and includes anti-roll features. The instrumentation is provided in a forward end of the device and is capable of being plugged into the balance of the device for rapid repair and replacement. The power supply is contained in a rear end of the device and the case forms a portion of the power supply circuit. The device employs a startup test of the sensor and the power supply. Also, the power supply is continuously monitored. The device also employs a lost device locator such that the device can be readily located after being misplaced. Moreover, the device has a signal expanding feature that allows a heat source that is rapidly passed over to be relocated on subsequent sweeps of the device.Type: GrantFiled: December 19, 2001Date of Patent: January 6, 2004Assignee: The Knox CompanyInventors: Dohn J.
