Patent number: 10555622Abstract: A dispensing device comprises a loading chamber (12), a dispensing chamber (14), located beneath the loading chamber, a gate or shutter (24) movable between a first open position and a second closed position to allow selective communication of the loading chamber and the dispensing chamber. The device further comprises a first indicating means in the form of a first indicator member (114) which is retainable in a first-retracted position when the gate or shutter (24) is in the closed position and which is displaceable to a second, extended position when the gate or shutter is moved from the closed position to the open position. The device further comprises second indicating means (116) which is actuable to display a second visible signal to indicate that the first signal has been observed.Type: GrantFiled: June 18, 2008Date of Patent: February 11, 2020Inventor: Stephen William Clarke

Patent number: 9476739Abstract: An indicator device comprises a first slide member (22) mounted on a planar base (1). The first slide member (22) is displaceable between a first position in which it reveals a first status indicating area (26) indicative of a first condition or state and a second position in which it reveals a second status indicating area (28) indicative of a second condition or state. A second slide member (30) is mounted on the base (10) and is displaceable into and across the path of the first indicator member (22) when the first indicator member is in the first position, to inhibit displacement of the first indicator member. The second indicator member (30) is displaceable between a first position in which it does not inhibit the displacement of the first indicator member (22) and a second position in which it inhibits the displacement of the first indicator member to its second position. The device may also be provided with one or more RFID tags (80, 82, 84) to permit remote monitoring of the status of the device.Type: GrantFiled: February 6, 2012Date of Patent: October 25, 2016Inventor: Stephen William Clarke

Publication number: 20140292493Abstract: An indicator device (D) comprises a base (10, 12) and a first indicator member (30) slidably mounted in a window (28) in the base between a first position indicative of a first condition or status of the device and a second position indicative of a second condition or status of the device. A releasable retention means, e.g. in the form of a pawl or catch (40), is mounted on the base, for retaining the first indicator member (28) in the first position and release means (48) are operable from outside the base for releasing the retention means, wherein the first indicator member (30) moves toward the second position on the release of the retention means (40).Type: ApplicationFiled: November 9, 2012Publication date: October 2, 2014Applicant: HURST GREEN PLASTICS LIMITEDInventors: Stephen William Clarke, Thomas Benjamin Sharples

Patent number: 7146246Abstract: A dispenser has an upper loading chamber (38), a dispensing chamber (40) located beneath the loading chamber, first and second openable covers (24, 34) for the loading chamber (38) and a dispensing chamber (40) and a gate means (32) mounted in the housing between the two chambers and forming a lower wall of the loading chamber (38). The gate means (32) is movable to allow selective communication of a loading chamber (38) and the dispensing chamber (40) to allow the contents of the loading chamber to fall into the dispensing chamber (40). Opening of the gate means (32) to an extent sufficient to allow the contents to fall into the dispensing chamber generates a signal from a limit switch (59) indicative that the loading chamber (38) is empty.Type: GrantFiled: March 15, 2002Date of Patent: December 5, 2006Inventor: Stephen William Clarke
