Patent number: 8448357Abstract: Couplers for attaching an accessory to an excavator arm of an excavator. Couplers having a first side for attaching the coupler to the excavator arm and a second side onto which the accessory will be coupled. The coupler includes a latch for selectively securing and releasing an attachment pin of the accessory in a jaw, groove, hook or slot in the second side of the coupler. The coupler is fully controllable from within the cab of the excavator and it allows improved security in the securement of the accessory to the coupler, i.e. preventing accidental decouplings, but while still allowing intentional decoupling operations to be carried out without undue burden.Type: GrantFiled: August 1, 2012Date of Patent: May 28, 2013Assignee: Miller UK LimitedInventors: Gary Miller, Ronald Keith Miller, Gary Pendleton, Howard Reay, Paul Grant

Publication number: 20120230760Abstract: A coupler includes first and second attachment pin jaws. A first latching mechanism is associated with the first jaw. The first latching mechanism has an arm connected to and extending away from a latching member. A second latching mechanism is associated with the jaw. The first and second latching mechanisms are adapted to latch the first and second attachment pins of an accessory in or on the first jaw and the second jaw, respectively. The second latching mechanism is powered for movement between a latching position and a non-latching position. The first latching mechanism is operatively connected to, or connectable with, the second latching mechanism to allow it to selectively operate the first latching mechanism between latching and non-latching positions by means of a groove or flange or finger on the second latching mechanism. A magnet is provided to ensure a correct disengagement of the first latch latching mechanism.Type: ApplicationFiled: March 7, 2012Publication date: September 13, 2012Applicant: MILLER INTERNATIONAL LTD.Inventors: Howard Reay, Gary Miller, Ronald Keith Miller

Publication number: 20110313625Abstract: A coupler (24) for coupling an accessory (28) to an excavator arm (12) of an excavator (10), the coupler comprising a first jaw (30) that points in a generally longitudinal direction relative to the frame of the coupler (24), the jaw (30) being for receiving a first attachment pin of an accessory (28) and having a first sensor (40) for detecting the presence of an attachment pin therein, the coupler (24) further having a second jaw (32), or a latch (34), longitudinally spaced from the first jaw (30), and being for receiving a second attachment pin of the accessory (28), and having a second sensor (42) for detecting the presence of an attachment pin therein. The sensors (40, 42) transmit or send signals to a receiver (46, 48) for notifying the driver of the coupling status of the coupler (24) with respect to the accessory (28).Type: ApplicationFiled: November 3, 2009Publication date: December 22, 2011Applicant: Miller International LimitedInventors: Gary Miller, Ronald Keith Miller, Doreen Jacqueline Miller

Patent number: 6922926Abstract: The coupler has a pair of spaced side frames (25a) in each of which a first hook like aperture (13) is provided for engagement with a first pivot pin provided on an excavator bucket and wherein a locking pin (23) is moveable from and into a locking position in which it prevents the latching hook (17a) from disengage from a second pivot pin (9a), (9b) or (9c) on the bucket there being a plurality of locking positions for the pin to accommodate different buckets. Preferably, a plurality of spaced apertures (27), (29), (31) are formed on each of the side frames (25a), those in one frame being transversely aligned with those in the other frames, and preferably also a plurality of spaced apertures (33, 35) and/or latching surfaces are formed on the latching hook or on an extension thereof, through or against which the locking pin (23) can be passed or can bear to prevent relative movement between the hook (17a) and side frames.Type: GrantFiled: February 9, 2001Date of Patent: August 2, 2005Assignee: Miller UK LimitedInventors: Gary Miller, Ronald Keith Miller, Paul Maguire

Patent number: 6481124Abstract: A coupler (11) for connecting a dipper arm (3) of an excavator to a bucket (1) without the need for the operator of the excavator to leave the cab of the excavator, the coupler (11) having means for connecting it to the end of the dipper arm, and means, including a latching hook (17) for connecting it to one of a plurality of different buckets (1) and wherein locking means (25) is provided to prevent inadvertent unlatching of the latching hook (17), said locking means (25) being operable from the cab. The locking means may be gravity operated and include resiliently deformable means (27), thereon to prevent unlatching when the coupler (11) is inverted. Alternatively, it may be spring (71) operated in which case, further means (73, 75) is provided to move the locking means against the bias of the spring. Preferably, the hook (17) has a special internal profile (56, 57, 61) so that when it is supporting the weight of a bucket, it will tend to move to a latching position, not to an unlatching position.Type: GrantFiled: June 11, 2001Date of Patent: November 19, 2002Inventors: Doreen Jacqueline Miller, Gary Miller, Ronald Keith Miller
