c. M KAY AUTOMATIC CARD SHUFFLER AND DEALER 5 Sheets-Sheet 2 Filed Jan. 22, 1951 INVENTOR Patented Nov. 1, 1932 UNITED STATES PATENT OFFICE I orr, MassAoHu'sErrs AUTOMATIC CARD SHUFFLER AND DEALER Application filed January 22,- 1931. Serial No, 510,365.

This invention relates to apparatus for shufliing articles and dealing them indiscriminately. It will be herein disclosed as embodied'in a machine designed particularly for shufliing and dealing playing cards.

1 In playing various card games it is-necessary to shuflie the cards in the pack and then to deal the hands to the players. A fair deal requires a very thorough shufiiing of the cards. It is an important object of the present invention to devise a machine or apparatus for performing the function of shufliing the cards and dealing them indiscriminately V to provide the desired number of hands.

While the invention will be herein disclosed as embodied in a machine designed especially for shufliing a pack of cards and dea ing the pack into four hands, it will be evident that minor modifications only would be re uired to adapt the machine for dealing a di erent number of hands, and that essentially the same principles could also be used in shufliing and-dealing other articles. 7 The nature of the invention will be readily understood from the following description when read inconnection with the accompanying drawings, and the novel features will'be particularly pointed out in the appended claims. In describing my invention in detail, reference will be had to the accompanying drawings wherein like charactersdenote like or corresponding parts throughout the several views and in which: t

Figure 5 is a section on line ure 2.

Preliminary to a detailed description of the a machine shown in the drawings, it may be stated that the machine comprises a container or magazines for holding a pack of cards, mechanism for feeding the cards one at a time out of the magazine, sorting mechanism for, distributing the cards to divide the entire pack into four hands, selectors which control the sorting operation, and means for selecting or choosing the selectors indiscriminately. In this particular machine one selector is provided for each card and the selectors are divided into four groups, the individuals of each group differing from those of the other groups. Since the selectors which control the sorting of the successive cards are chosen indiscriminately, the final distribution of the cards is made indiscriminately and is determined simply by chance.

The device comprises a container or magazine 1 for holding a pack of cards, consisting of a rectangular box with one side open for the insertion of the cards. The bottom inclines slightlydownward toward the front and is slotted to permit the rubber tired wheels 2 and 3 to enter and push the bottom card forward. In line with the slots 44 and 45 are two beads 46 and 47 designed to place the most friction where the moving force is being applied. The front of the container has a horizontal slot 48 with two fingers 49 and 50 extending downward opgosite the beading on the bottom, leaving a istanoe less than the width of two cards betweenthe fingers and the heading so not more than one card can be forced out of the container at one time. The eover 4 fits inside the walls of the container and is of sufficient weight to :1 ply a constant pressure on the cards. The ottom of the cover is also beaded to correspond to the bottom of the container.

. The rubber tired wheels 2 and 3 rotate on a shaft in the frame 5 which is pivoted on the main shaft 6 and held with the wheels pressing upward by coil spring 7 attached to a prolongationof one side of the frame over the shaft 6. The frame is pulled downward, bringing the rubber tired wheels out of contact with the cards by the earn 8 forcing down the lever 9 which is attached to arm 10 of frame 5. The cam 8 is arranged so it will allow the frame 5 to return and permit the rubber tired wheels to force out one card at each revolution of the shaft 6 unless stopped by the failure of a ball to come out of the hopper, as will be explained later. The shaft holding the rubber tired wheels 2 and 3 is rotated by gears 11 and A series of fifty-two balls is provided divided into four sets of different sizes with thirteen of each size. The halls are contained in the hoppers13 and 14 which are fastened together by a circular casing fitting over the circular casing 15vvghich surrounds the wheel 16. The casing 15 has a slot to admit the arm 17 of lever 18. This arm normally rests in a. groove 51 in wheel 16. This casing 15 also has a chute 19 open at the top which corresponds with'a similar opening in the hoppers 13 and 14 and permits the balls to fall out of the upper hopper 13 and rest on the wheel 16. As the wheel 16 is rotated, a ball falls into the indentation of the wheel and is forced out through an opening in the chute under arm 17 of lever 18. This lever operates to prevent more than one ball being delivered at each turn of the wheel 16. It should also be noted that the diameter of the balls is so arranged thatthe largest ball is less than twice the diameter of the smallest ball and that the indentation in wheel 16 is of a size to admit the largest ball/but not large enough to allow two of-the smallest balls to lie side by side in the bottom of the indentation and so pass out at one revolution of the wheel 16. Having passed under the arm 17, the ball falls into the lower hopper 14 through an opening in the bottom of casln '15. After all the balls have been carried out of hopper 13, the position of the hoppers can be reversed by turning the hoppers half way around, which brings hopper 14, containing all the balls, on top.

As a'ball is forced out under arm 17 of lever 18," lever 18 is raised to a height corresponding to the size of the ball delivered and the latch 20 catches in the notch at the end of lever 18 and holdsit in substantially the position to which it has been moved by the ball. The raising of lever 18 by the-ball also moves the lower end of arm 21 inwardly and permits frame 5 to move upward under the force of spring 7 and start the delivery of a' card. Arm 10 has a small projection 22, Fig. 1, which is caught by arm 21, pre

venting the rubber tired wheels 2 and 3 from comingin contact with the cards except when a ball is delivered. The latch 20 is released by the pin 23 inserted in cam 8 just prior'to the time the wheel 16 starts to force another ball under-the arm 17.

A receiver 24 with four compartments, 25,

26, 27 and 28, is provided detachable from the rest, ofythe mechanism. When the machine is in use, however, it is inserted by slidin along frame '29 until the lugs 30 and 31 fafi into the slots 32 and 33. -The receiver then rests on lever 34. The arm 35 is attached firmly to lever 34 and is slidably mounted on the vertical arm of frame 29 and projects over the cam 8. It is also attached to lever 18 by means of screw 36 passing through slot 37. Slot 37 is arranged so arm 35 can be raised or lowered without interfering with lever 18. If

a ball has'been delivered, however, and lever 18 held in any of the four positions by latch 20, then arm 35 will be held by lever 18- and will not be allowed to follow the cam 8 down. Asthe cam 8 is rotated, the arm 35 raises the lever 34 which moves the receiver 24 in an arc in front of the rubber tired wheels 38, 39, 40 and 41: ALthe top of the arc the compartment 28 of receiver 24 isslightl'y above the place where a card would be delivered by the rubber tired wheels 38 and 39. At the bottom of the arc 'the compartment 25 of receiver 24 will be slightly below the place where a. card would be delivered by the rubber tired wheels 38 and 39. The levers and the notches in, the end of lever 18 are so arranged, however, that lever 18 will stop the receiver 24 on its downward swing so that ,the compartment in the receiver corresponding tothe size of the ball which raised lever 18 will be held in position to receive the card.

The rubber tired wheels 38 and 39 are mounted on shaft 6 and the rubber tired wheels 40 and 41 are mounted on another shaft immediately above in such a position that a card forced out of container 1 comes ing the balls is on top. As themain shaft 6 is rotated by the hand crank, all the rubber tired wheels are rotated as well as wheel 16 and cam 8. The position of the indentation in wheel 16 is located so the cam 8 has raised the receiver 24 to the top of its arc and permitted the frame 5 to, rise to a position where the rubber tired wheels 2 and 3 come in contact with the cards at the moment a ball is forced under arm 17. The raising of lever 18 by the ball permits a card to be forced out by the rubber tired wheels 2 and 3. The cam 8 18 so arranged that as soon as the card has started between the rubber tired wheels 38, 39, 40 and 41, the frame 5 is drawn down, thus preventing the starting of another card from container 1 until the cam 8 has completed its revolution. Lever 18 has also been held in the position placed by the ball by latch 20. This holds arm from following the cam down and arm 35 holds lever 34 which stops receiver 24 in its downward arc and holds it in a position to receive the card in the compartment corresponding to the size of the ball. The size of the rubber tired wheels 38, 39, and 41 is so arranged that they w ll deliver the card before the cam 8 starts raising the receiver and before the pin23 releases the latch.. It will be apparent that a card is delivered at each revolution of the shaft 6 and that the receiver 24 will have been stopped in position to receive thirteen cards in each compartment in fifty-two revolutions of shaft 6. The order in which it has stopped at the various compartments will, however, depend on the order in which the various sizes of halls are taken out by the wheel 16.,

It will thus be evident that in this machine the distribution of successive cards into the several compartments of the receiver 24 is controlled by the size of the particular ball selected or picked by the wheel 16 from the mass of balls in the upper hopper during the feeding of each card. Since this picking or choosing of the selectors for each card is made indiscriminately and is entirely a matter of random or chance, the sorting of the cards into the four compartments of the receiver is made indiscriminately and is controlled simply by chance. The ,shufliing of the cards, therefore, occurs automatically in connect on with the dealing of them and a fair deal is always ensured. 1 I

A casing 42'is provided to cover the mechanism with a topsuitable for holding a score pad 43 for recording the results of the game.

. While I have herein shown and described one embodiment of my invention, it will be evident that the invention may be embodied in a great variety of other forms without departing from the spirit or scope thereof. For example, selectors of other constructions can be used. Also, the organization and arrangement of the elements of the machine ecessarily will depend upon the nature 0 the articles which it handles, the requirements of the game in which such articles are to be used, and the particular use to be made of the machine.
