Patent number: 10830373Abstract: A dump handle locking device inhibits tampering with a dump handle of a tank dump valve assembly. A handle portion and a barrier portion interface with respective ends of the tank dump valve assembly. The handle portion and the barrier portion are releasably locked together through a lock mechanism, which restricts displacement of the dump handle that controls movement of a barrier covering the pipe opening. A key regulates fastening and unfastening of the lock mechanism. Consequently, the dump handle is restricted from axial displacement, remaining in a closed position. In some embodiments, handle portion is a valve handle box that encapsulates the dump handle, and barrier portion is a lock plate interfacing with pipe section in tank dump valve assembly. In other embodiments, handle portion is a valve handle cable that attaches to the dump handle, and barrier portion is a barrier cable that attaches to the pipe section.Type: GrantFiled: February 2, 2019Date of Patent: November 10, 2020Inventor: Kenneth Wayne Baker

Patent number: 8091587Abstract: A system and method for installing and removing a flow restrictor assembly in a shower, while prevents tampering with the flow restriction system thus installed. Tampering is prevented by concealing the flow restrictor assembly behind a shower wall, attached directly to a water supply line. The system further prevents tampering by concealing the tool-hole necessary for its removal behind a flow restrictor disk, so that there are no visible means of removing the flow restrictor assembly. The flow restrictor assembly threads onto a showerhead arm and the flow restrictor assembly with the attached showerhead arm threads directly into the water line. When the showerhead arm is unthreaded, the flow restrictor assembly remains connected to the water line by an external screw thread. The flow restrictor must be removed to reveal the tool-hole which may only then be engaged by a tool for removal.Type: GrantFiled: January 28, 2010Date of Patent: January 10, 2012Inventor: David Schwartz
