Abstract: An apparatus is disclosed for attachment to a loader for moving materials. The apparatus includes a bucket having a first and a second end. A support is secured to the first end of the bucket for supporting the bucket relative to the loader. A front plate is pivotally secured to the second end of the bucket. A clam shell closure has a first and a second extremity. The first extremity is pivotally secured to the first end of the bucket, the arrangement being such that in operation of the apparatus, when the closure pivots from an open disposition thereof to a closed disposition thereof in which the second extremity of the closure cooperates with the front plate, the materials are secured between the bucket, front plate and the closure. The apparatus also includes a device for pivoting the front plate from a first location for loading the materials to a second location in which the front plate cooperates with the second extremity of the closure for moving the materials.

Abstract: An improved auger is used for conveying flowable materials, such as liquid and semi-solid manure, through a bed of a container such as a manure spreader and out through a discharge opening. The auger has a shaft with a back end and a front end, a continuous blade, and paddles for discharging the manure. The continuous blade extends radially outwardly from the shaft and includes helical portions and at least one plate portion which is substantially perpendicular to an axis of the auger. The plate portions extend between the helical portions of the blade to make the blade substantially continuous. The rotation of the auger causes helical portions of the blade to accelerate the manure in a direction of the front end wall and causes the plate portions to slow the movement of manure so that the rate of flow of manure is controlled and boiling action of manure against the front end wall of the container is inhibited.
