Patent number: 5938398Abstract: A dispensing bucket apparatus that removably connects to a loader vehicle. The apparatus is a bucket that is adapted to receive and hold a flowable material and has an exit opening in its front end that is selectively opened and closed by a gate. The position of the gate may be controlled by the user from within the loader vehicle to control the flow and flow rate of the flowable material from the bucket. The side walls of the bucket converge toward the front of the bucket and form a funnel that directs the flowable material to the exit opening. The construction of the apparatus is such that the user can view the pour at all times and, thereby, reduce spillage and waste. An alternate embodiment includes a tilting mechanism that provides for attachment of the bucket to a forklift and for tilting of the bucket. A removable chute allows the pour opening to be extended further from the front of the bucket.Type: GrantFiled: October 10, 1997Date of Patent: August 17, 1999Assignee: Akard & GriffinInventor: Rodney E.
