Abstract
A device for shuffling objects such as lottery balls is provided, disposed at the base of a generally spherical enclosure of a lottery machine carrying separately identifiable objects, the shuffling device including first and second concentric rotating parts which together form a substantially contiguous support surface for the objects, and the surfaces of which carry substantially radial slender projecting elements which, in operation, are intended to hit the objects, and also including a driver for rotating the first and second parts at speeds which differ in terms of value and/or direction.
Claims9
A device for shuffling objects such as lottery balls, disposed at the base of a generally spherical enclosure of a lottery machine, into which are inserted objects, each having a means of identification, said shuffling device comprising:
- a first and a second rotating part (5, 6) each of said first and said second parts having an inner surface (5A, 6A) facing an inside of the enclosure, each of said surfaces carrying a plurality of substantially radial slender projecting elements (7) intended to hit said objects (1),
- said first and second parts further being concentric rotating parts (5, 6), each equipped with slender projecting elements (7), wherein said first part surrounds and rotates around said second part, and wherein said first and said second parts together form a substantially contiguous surface for supporting said objects, and
- means (8, 9) for driving said rotating parts (5, 6) at speeds that differ in terms of value and/or direction.
A drawing machine comprising:
- a generally spherical enclosure;
- a device for shuffling objects therein disposed at a base of said spherical enclosure;
- and
- a plurality of objects disposed within said spherical enclosure;
- wherein
- said device for shuffling objects further comprises a first and a second rotating part, each of said first and second rotating parts having an inner surface facing an inside of said enclosure, said inner surfaces of said first and second parts being positioned such that said inner surfaces form a substantially contiguous surface, and wherein said first part rotates around a perimeter of said second part, each of said inner surfaces carrying a plurality of substantially radially extending slender projecting elements thereon, and means for driving said first and second parts at speeds that differ in terms of value and/or direction.
