Abstract

Apparatus for randomly cutting a deck of cards. The apparatus supports the deck of cards in stacked registration and slides the cards in a common direction to offset or "shingle" the cards in the deck. A probe is moved into the offset zone of the shingled deck and is caused to stop at a randomly selected location in the zone. Means is provided for moving the shingled deck relative to the probe to engage the leading edge of the probe with a card to separate the card from a contiguous card and randomly cut the deck into a sub-deck on one side of the probe and a sub-deck on the other side of the probe. The cut is preferably made in the range of cards 20-32 in a 52 card deck.

Claims

1. Apparatus for randomly cutting a deck of cards which comprises:

a. support means for supporting a deck of cards in stacked registration;

b. means for sliding each card in the deck in a common direction and to a greater extent than the preceding card in the deck to thereby offset or shingle the cards in said direction to define an offset zone between the least offset card and the most offset card;

c. a probe having a leading edge;

d. means for moving the leading edge of the probe into said zone;

e. means for randomly determining the location inside said zone to which said leading end of said probe is moved; and

f. means for moving the deck relative to the probe transversely to said, direction, to thereby engage the leading edge of the probe with one of the cards in the deck to separate that card and all cards having greater offset than the one card from the contiguous card and all other cards having lesser offset than the one card thereby cutting the deck into two randomly, sized sub-decks.

2. The apparatus of claim 1 wherein said support means supports the deck with the cards in a horizontal plane.

3. The apparatus of claim 2 wherein the probe is tongue-like, is disposed horizontally and has sufficient area to lift and support a card.

4. The apparatus of claim 3 wherein said means for moving the leading edge of the probe into said zone moves the leading edge horizontally.

5. The apparatus of claim 4 and means for moving the leading edge and the probe substantially completely beneath a card to thereby lift and support the card and all cards above it on the probe and cut the deck into a first sub-deck supported on said support means and a second sub-deck supported on said probe.

6. The apparatus of claim 5 and means for pinching the cards comprising the second sub-deck against the probe to thereby hold them in a stationery position against the probe.

7. The apparatus of claim 6 and means for moving the probe and the second sub-deck supported on the probe horizontally out of vertical registration with the first sub-deck.

8. The apparatus of claim 3 and a roller disposed for rotation on a horizontal axis transverse to the direction of movement of the probe at the leading edge of the probe.

9. The apparatus of claim 1 wherein the probe is tongue-like and has sufficient area to support a card.

10. The apparatus of claim 9 and means for moving the leading edge of the probe substantially the full length of a card to thereby completely separate the card from the contiguous card and cut the deck into a first sub-deck on one side of the probe and a second sub-deck on the other side of the probe.

11. The apparatus of claim 10 and means for pinching the cards comprising the second sub-deck against the probe to thereby hold them against the probe.

12. The apparatus of claim 11 and means for moving the probe and the second sub-deck pinched against the probe out of registration with the first sub-deck.
