A front and rear wheel assembly having an axle housing with a wheel rotatable on a shaft at each end of the axle housing and a connecting member connecting a central portion of each axle housing. A right and left side upright support frame affixed to a top surface of each axle housing between the connecting member and the wheel. The upright support frames each have multiple engagement ridges on a top surface and side edges adjacent the top surface. A movable planar platform is slidably mounted with its C-channels enclosing the side edges of the support frame. A latch portion of the movable planar platform having a downwardly directed spike engaging the engagement ridges on the support frame. Lifting of the latch allows movement in or out of the planar platforms with respect to the connecting member to accommodate containers of different widths resting on the planar platforms.

1. An adjustable width carriage for supporting and carrying containers of varying widths, the carriage comprising:a front and rear wheel assembly connected by a central connecting member; the front and rear wheel assemblies each having an axle housing having a shaft at a first and second end with a wheel rotating on the shaft at the first and second end; a right side upright support frame affixed to a top surface of the axle housing between the central connecting member and the first end of the axle housing and a left side upright support frame affixed to the axle housing between the central connecting member and the second end of the axle housing in the front and rear wheel assemblies; the upright support frames each having on a top surface multiple engagement ridges, the top surface terminating in side edges adapted to engage oppositely positioned C-channels on a movable planar platform; the movable planar platform having a top and bottom surface, the platform slidably mounted along the side edges of the support frame; and a latch portion of the platform having a bottom surface with an engagement spike complimentary to the engagement ridges on the top surface of the upright support frame so that upon lifting of the latch the spike disengages from the engagement ridges and movement of the planar platforms can be achieved by sliding the planar platforms in or out with respect to the central connecting member to accommodate containers of different widths resting on a top surface of the planar platform. 2. An adjustable width carriage according to claim 1 wherein the central connecting member has a front portion snapping into an opening in the front axle housing and a rear portion snapping into an opening in the rear axle housing.3. An adjustable width carriage according to claim 1 wherein a rope is attached through a bore in the front wheel assembly for pulling the carriage.4. An adjustable width carriage according to claim 1 wherein an open container is mounted on the planar platforms.5. An adjustable width carriage according to claim 4 wherein the open container is held in place by a pair of U-clamps, each affixed to a strap, the strap attached distally from the U-clamp to the wheel assembly.6. An adjustable width carriage according to claim 4 wherein the planar platforms have an upright wall at an outboard end to prevent sideways movement of the container.7. An adjustable width carriage according to claim 1 wherein a closed container is mounted on the planar platforms.8. An adjustable width carriage according to claim 7 wherein the closed container is held in place by a pair of straps, each attached at a bottom end to the front and rear wheel assemblies, respectively and engaged together at a top end by a male and female snap lock fastener.9. A four wheeled carriage for supporting and carrying containers of varying widths, the carriage comprising:a front and rear wheel assembly, each having an axle housing with a wheel rotating on a shaft at a first and second end of the axle housing; a connecting member attached to a central portion of the front and rear wheel assemblies; a right side upright support frame affixed to a top surface of the axle housing between the central connecting member and the first end of the axle housing and a left side upright support frame affixed to the axle housing between the connecting member and the second end of the axle housing on the front and rear wheel assemblies; the upright support frames each having on a top surface multiple engagement ridges positioned to receive a spike on a bottom surface of a latch, the top surface terminating in side edges; a movable planar platform having a top surface with the latch formed at an inboard end of the platform, C-channels formed on opposed inner sides of the planar platform to receive the side edges of the upright support frame top surface; and the spike on the bottom surface of the latch portion of the platform normally contacting the engagement ridges on the top surface of the upright support frame, but upon lifting of the latch the spike is disengaged from the ridges and movement of the planar platform can be achieved by sliding the planar platform in or out with respect to the connecting member to accommodate containers of different width resting on a top surface of the planar platform. 10. A four wheeled carriage according to claim 9 wherein the front portion of the connecting member snaps into a through bore in the front axle housing and the rear portion of the connecting member snaps into a through bore in the rear axle housing.11. A four wheeled carriage according to claim 9 wherein the right side upright support frame and left side upright support frame are integral with the respective axle housings.12.
