An apparatus and methodology is provided for filling portable containers, such as sandbags, with aggregate materials. The utility utilizes a transfer mechanism to selectively transfer aggregate between a supply of aggregate material (e.g., sand) and first and second filling stations that direct received aggregate into portable containers or bags. The transfer mechanism is operative to alternately supply aggregate between the first and second filling stations and operates primarily under the force of gravity.

1. An apparatus for filling portable storage containers with aggregate material, comprising: a supply hopper having an inlet and an outlet;a first bag filling hopper and a second bag filling hopper, each having an inlet and an outlet; anda carriage located between the supply hopper and the first and second bag filling hoppers, the carriage being movable about an rotational axis between a first position and a second position, said carriage including: a first transfer hopper, the first transfer hopper having a first open end adapted for alignment with the outlet of the supply hopper in the first position and the inlet of the first bag filling hopper in the second position; anda second transfer hopper, the second transfer hopper having a first open end adapted for alignment with the inlet of the second bag filling hopper in the first position and the outlet of the supply hopper in the second position. 2. The apparatus of claim 1, wherein: the first transfer hopper further includes a first volume between said first open end and a first closed end; andthe second transfer hopper further includes a second volume between said second open end and a second closed end. 3. The apparatus of claim 2, wherein aggregate received from said supply hopper is maintained in said first volume in said first position and flows out of said first open end of said first volume in said second position. 4. The apparatus of claim 2, wherein, in said first and second position of said carriage, a first centroid of said first volume and a second centroid of said second volume are disposed on opposing sides a vertical reference axis passing through said rotational axis of said carriage. 5. The apparatus of claim 1, wherein said carriage supports said first and second transfer hoppers at first and second angular positions about said rotational axis. 6. The apparatus of claim 5, wherein said first and second angular positions are offset by at least 90°. 7. The apparatus of claim 5, wherein said first and second angular positions are offset by at least 100°. 8. The apparatus of claim 5, wherein the carriage further comprises: a radial surface extending between the first inlet of the first transfer hopper and the second inlet of the second transfer hopper, wherein the radial surface is disposed beneath the outlet of the supply hopper as the carriage moves between the first and second positions. 9. The apparatus of claim 8, further comprising: at least one seal element attached to at least one edge of said outlet of said supply hopper, wherein said at least one seal element is adapted for engagement with the radial surface as said carriage moves between said first and second positions. 10. The apparatus of claim 1, further comprising: a first biasing member, wherein the first biasing member is biased by said carriage when the carriage moves to the first position; anda second biasing member, wherein the second biasing member is biased by said carriage when the carriage moves to the second position. 11. The apparatus of claim 10, wherein said first biasing member applies a restoring force to the carriage to displace the carriage from the first position toward the second position, and wherein the second biasing member applies a restoring force to the carriage to displace the carriage from the second position toward the first position. 12. The apparatus of claim 1, further comprising: a first latch member adapted to engage said carriage in said first position and maintain said carriage in said first position; anda second latch member adapted to engage said carriage in said second position and maintain said carriage in said second position. 13. The apparatus of claim 12, wherein each of said first and second latch members is operable to move between a latching position engaging said carriage and a release position releasing said carriage. 14. The apparatus of claim 1, wherein the outlet of the first and second bag filling hopper further comprises: a lip disposed transverse to a central axis of the outlet, wherein the lip is adapted to be disposed within a portable storage container. 15. The apparatus of claim 1, further comprising: a frame supporting said supply hopper, said carriage and said first and second bag filling hoppers. 16. The apparatus of claim 1, wherein said supply hopper comprises a plurality of outlets and further comprises: a corresponding plurality of sets of first and second bag filling hoppers; anda corresponding plurality of carriages each including first and second transfer hoppers. 17. A method for filling multiple portable storage containers with aggregate material, the method comprising: filling a supply hopper with an aggregate material, said supply hopper having an inlet end and an outlet end;draining the aggregate material through said outlet end of said supply hopper into a first open end of a first transfer hopper supported by a rotating carriage, wherein said rotating carriage is in a first position;rotating the carriage to a second position wherein said first open end of said first transfer hopper engages an inlet of a first bag filling hopper and a second open end of a second transfer hopper supported by the rotating carriage is aligned with said outlet end of said supply hopper;wherein, in the second position, the aggregate material in said first transfer hopper spills into said first bag filling hopper and aggregate material in said supply hopper drains into the second open end of said second transfer hopper. 18. The method of claim 17, wherein a mass of said aggregate material in said first transfer hopper, acting under gravity, rotates said carriage between said first position and said second position. 19. The method of claim 17, further comprising: locking said carriage in said second position while the aggregate material in said first transfer hopper spills into said first filling hopper and aggregate material in said supply hopper drains into the second open end of said second transfer hopper. 20. The method of claim 17, wherein: upon said aggregate material in said first transfer hopper at least partially spilling into said first filling hopper, a mass of said aggregate material in said second transfer hopper, acting under gravity, rotates said carriage between said second position and said first position. 21. The method of claim 17, further comprising: blocking the outlet end of the supply hopper as said carriage moves between said first and second positions.
