Patent ID: 7364172

Claim:
A device for use with a bucket having a bottom surface of a given diameter, a sidewall, an interior chamber surrounded by the bottom surface and the sidewall and a top circumference of a given diameter at the top of the sidewall, the device comprising: a. a receiving section having a bottom surface of a given diameter and a circumferential sidewall with a top circumference of a given diameter, the diameter of the bottom surface being approximately the same as the diameter of the bottom surface of the bucket and the diameter of the top circumference being slightly larger than the diameter of the bottom surface of the bucket so that when the bucket is inserted into the receiving section, a press fit is achieved; b. a sealing section connected to and surrounding the receiving section, the sealing section having an exterior sidewall and an interior sidewall which surrounds the circumferential sidewall of the receiving section, a gap of a given diameter spaced between the exterior sidewall and the interior sidewall of the sealing section, the diameter of the gap being only slightly larger than the diameter of the top circumference of the bucket so that a press fit is achieved when the sealing section is placed on top of the bucket; c. the bottom of the sealing section having a lower surface with a multiplicity of rolling members rotatably attached to the lower surface of the bottom of the sealing section, the rolling member and the attachment means each having a given height; d. a receiving means attached to the lower surface of the bottom of the sealing section, the receiving means having a first rail with a vertical wall and a horizontal wall and a second rail with a vertical wall and a horizontal wall, the vertical walls being parallel and spaced apart and the horizontal walls being in the same plane, parallel to the lower surface of the bottom of the sealing section and extending toward each other to form an interior channel between the rails; and e. a supporting platform comprising a supporting base having a height equal to the height of each of the multiplicity of wheels and their attachment means and a joining beam with a transverse tightening means, the joining beam received within the interior channel of the receiving means and tightened therein by said tightening means.
