To prevent or minimize bridging of material to be dispersed within a containment vessel, a rotatable auger is positioned in close proximity to a curvilinear inner wall surface of the vessel. The auger has an axis that moves parallel to the curved wall surface in a manner such that the auger flights maintain a close working relationship relative to the curved wall surface as the auger is positioned for movement therealong. A spreader apparatus is positioned to receive material dispensed through the vessel outlet port to broadcast the dispensed material externally of the vessel.

I claim: 1. A dispensing apparatus for particulate material comprising: (a) a vessel configured to retainably hold a charge of particulate material to be dispensed, said vessel comprising: (i) opposed end walls; (ii) a bottom wall laterally extending between and connected to the opposed end walls; (iii) a back wall obliquely connected to said bottom wall and laterally extending between and connected to said end walls, said back wall having an inner surface extending longitudinally from said bottom wall substantially to an upper edge of the vessel; and (iv) said vessel defining an outlet port through which said particulate material passes when dispensed from said vessel, said outlet port being formed through at least one of said opposed end walls or said back wall and extending substantially from said bottom wall and substantially up to said vessel upper edge; (b) an auger having an axis of rotation and mounted within the vessel such that the auger axis of rotation is generally parallel to the inner surface of said back wall, said auger having a plurality of flights being configured and operable to move said particulate material within said vessel toward and through said outlet port; and (c) operator apparatus connected to rotate the auger about said axis of rotation and to longitudinally move the auger along the inner surface of the back wall from substantially the vessel upper edge to said bottom wall and such that the auger flights are maintained in close operative proximity to the inner surface as the auger dispenses said particulate material through said outlet port; and (d) wherein said auger moves the particulate material through said outlet port at substantially any longitudinal position along said inner surface of the back wall while removing the charge of material from the vessel from an upper surface of the charge. 2. The dispenser apparatus of claim 1, wherein said outlet port is positioned through one of said opposed end walls. 3. The dispenser apparatus of claim 1, wherein the vessel is an open vessel. 4. The dispenser apparatus of claim 3, wherein the vessel is configured as a bucket suitable for connection as an implement to a tractor. 5. A particulate material dispensing apparatus comprising: (a) an open vessel configured to retainably hold a charge of particulate material to be dispensed, said vessel comprising: (i) opposed left and right generally planar end plates; (ii) a lower generally planar wall member laterally extending between and connected to the opposed end plates; (iii) a back wall connected to said lower wall member and laterally extending between and connecting said opposed end plates, said back wall extending longitudinally from said lower wall member to an upper edge of the vessel, wherein said back wall defines a broad curvilinear surface extending from said lower wall and substantially up to said upper edge of the vessel; and (iv) said vessel defining an outlet port through which said particulate material is directed from said vessel, said outlet port passing through at least one of said opposed end plates or said back wall, said outlet port extending substantially from said lower wall and substantially up to said vessel upper edge; (b) an auger having an axis of rotation and mounted within the vessel such that the auger axis of rotation is generally parallel to said broad curvilinear surface, said auger having a plurality of flights operable to move said material within said vessel toward and through said outlet port; and (c) operator apparatus operatively connected to rotate the auger about said axis of rotation and to position said auger and said curvilinear surface for relative cooperative movement such that the auger axis is arcuately moveable substantially between the vessel upper edge and said lower wall so as to maintain the auger flights in close operative proximity to said broad curvilinear surface as the auger dispenses said particulate material through said outlet port; wherein during dispensing of said particulate material, said auger is positioned overlying said charge of material in said vessel such that said auger engages said material and dispenses said material from the vessel from the top of the charge of material. 6. The dispensing apparatus of claim 5, further including a spreader apparatus mounted to said vessel adjacent said outlet port, positioned to receive said material leaving said vessel through said outlet port and operable to dispense said material externally of said vessel in a broadcast manner. 7. The dispensing apparatus of claim 5, wherein said vessel comprises a bucket member. 8. The dispensing apparatus of claim 5, wherein said vessel is configured for attachment to a vehicle. 9. The dispensing apparatus of claim 5, wherein said operator apparatus comprises a linkage operatively connecting said auger to and for movement relative to said vessel. 10. The material dispensing apparatus as recited in claim 5, wherein said outlet port is positioned through at least one of said left or right opposed end plates of said vessel.
