CARD SHUFFLING DEVICE Filed Nov. 16, 1953 4 I5 Sheets-Sheet 3 E INVENTOR.

This invention relates to card shuflling devices, and particularly to a device which fans the edges of a plurality of cards across a fanning bar located centrally of the device.

While it is old in the art to provide devices for shuffling cards, both by the rotating roller method and by the fanning method, diificulty has always been experienced in the latter because of the engagement of the ends of the cards with each other, thereby interrupting the fanning operation. Different types of shuflling devices of the fanning type were sold in the trade but all of these proved unsatisfactory because the card edges moved into locking engagement with each other.

The present card shuffling device has overcome this difficulty by shaping the farming bar in a desired manner relative to a support for the cards which tilts the cards relative thereto and which prevents edge engagement. The device embodies a base portion, preferably having spaced legs on the bottom side and having a fanning bar on the upper side. The fanning bar has two portions which align the two groups of cards in holders mounted on plates which are pivoted to the base member and extend beneath projecting flanges on the fanning bar. As the plates are turned, the edges of the cards pass across another area of the fanning bar which is closer to the pivot than the first area, tothereby cause the cards to bend. The cards are slightly tilted since they rest upon the flange along the bottom edge of the fanning bar and the fanning bar is tapered from a thicker base to a thinner top to cause the bottom corners of the cards to be further bent so that they will move from the end of the fanning bar with a snap action. This will prevent the card from engaging an opposite card coming ofl? at the same time because of the snap action of both corners since only a point engagement could occur between the adjacent tilted edges. As a result, no particular care need be taken as to the manner of loading the cards into the card receiving receptacles or in operating the plates supporting the receptacles for moving the cards across the surfaces of the tanning bar. The receptacles are preferably of a width so that each may receive one and a half decks of cards when a three-deck pack is to be shuflled, and means are provided whereby two packs or a single pack may also be shuflied in the device.

Accordingly, the main objects of the invention are: to provide a card shuifiing device with card receiving receptacles which are pivoted to carry cards past a fanning bar to fan the corners of the cards thereacross; to provide receptacles for the cards which support the cards at an angle to the vertical and to the face of the fanning bar so that the major bend in the card occurs at the bottom forward corner thereof; to provide a snap action to the bottom corner edges of the cards as they are fanned from the fanning bar to cause them to overlap with each other rather than to move into and remain in edge-to-edge relationship with each other, and, in general, to provide a card shuffling device which is simple in construction, positive in operation, and economical of manufacture.

The card shuffling device of the present invention comprises a base member 20, having

fiat side areas

21 and 22 upon which the

quadrants

23 and 24 are secured for arcuate movement on pivots 25. At the forward edge of the base member 20, a raised portion 26 is provided, while a similar raised portion 27 is located adjacent to the pivots 25 to reduce the area of engagement between the bottom of the

quadrants

23 and 24 and surface of the

flat portions

21 and 22. A further raised portion 28 is located at the forward edge of the base member 20 which is aligned with the

quadrants

23 and 24 and which supports a stop block 29. The stop block limits the degree of movement of the cards as the quadrants are moved forwardly.

At the rear end of the plate 20, a fanning bar 31 is provided having faces 32 which are disposed parallel to the rear wall of the card receptacles 33 which are supported by the

quadrants

23 and 24. The faces 32 accurately align the cards in the receptacles when they are being loaded therein. A second pair of faces 34 is located at the sides of the fanning bar which is closer to the pivots 25 than the faces 32 so that the cards will be bent as they are advanced by the rotation of the receptacles about the pivots. The sides of the fanning bar at the end thereof have a pair of faces 35 which slope toward each other from the bottom to the top thereof, as clearly illustrated in Fig. 4. At the base of the fanning bar,

ledges 36 extend outwardly for receiving the end of the card which, as clearly illustrated in Fig. 4, tilts the forward edges of the cards to have them disposed at an angle to the vertical. As will be noted in Pig, 4-, the corner portions 37 are bent a substantial amount to produce a snap action to the corners as the cards are moved from the end of the fanning bar, to thereby have the cards overlap each other.

The

sectors

23 and 24 have arcuate corrugated mated edges 38 which act as teeth to retain the two sectors accurately positioned relative to each other. A knob 39 is secured to the forward end of each sector by which the sectors are pulled forwardly to rotate the receptacles 33 about the pivots 25 and thereby simultaneously fan the two half decks from the end of the fanning bar 31 into shufiled relation with each other. The cards are prevented from moving from overlapped position by the stop block 29 against which the foremost card engages as the tanning operation proceeds. This relationship of the cards to the block is clearly shown in Fig. 3 which illustrates the advanced position of the sectors after the fanning operation. It will be noted that the two terminal ends 41 of the sectors abut each other and therefore form a stop to limit further forward movement. In the same manner the arcuate portions 42 at the forward end of the sectors abut each other and limit the return movement of the sectors. The ends 41 remaining under the ledges 36 maintain the pivots 25 within theapeitures in the base 20, and through the deflection of the material of the sectors, the pivots 25 are assembled within the apertures 43 after the ends 41 have been inserted beneath the ledges 36. No means are required, therefore, to maintain the pivots 25 within the apertures.

The receptacles 33 are of a width to permit one and a half decks of cards to be placed therein when three decks are employed, as in a Canasta game. A filler block 44 is provided for reducing the width of the receptacles so that each receptacle will support a single deck of cards employed when two decks are used in a game. The filler block as herein illustrated has a tongue -15 in the wall 46 thereof and the receptacle has a slot 47 and a pivot 43 molded therein so that the tongue 45 may be heated and bent around the pivot 48, as illustrated more specifically in Fig. 5. In this manner, the block 44 may be either swung outwardly so that the full width of the receptacle is available for a deck and a half of cards, or swung inwardly when a single deck of cards is to be supported therein.

As will be noted in Figs. 4 and 10, a spring 4-9 has one end 51 secured to one of the pivots 25. the opposite end abutting an extending wall portion 52, the spring being so disposed with relation to the pivot that when the

quadrants

23 and 24 are pulled forwardly, the spring is further teusioned so that when the knobs 39 are released, the sectors will be returned to their initial position by the action of the spring. Thus, the entire shuttling device is composed of three members, as illustrated in the exploded view of Fig. 8. the base member and the two

sectors

23 and 24. As pointed out above, the two sectors are assembled on the base by first inserting the ends 41 beneath the ledges 36, after which the opposite ends of the rcceptacles are raised sutiiciently to slide the pivots across the corners of the base member until they snap into the apertures 43 where they will be retained in assembled position.

In Fig. 9, a slotted block 53 is illustrated which may be employed in place of the ller block id which eliminates the necessity of providing the slot 47 and pivot 43 in the receptacles and the heating and bending of the tongues 45 about the pivots. The block slides along the wall 46 beneath the top roiled edge 54, the block having a slot 55 which receives the wall. it will be noted that one side 56 or" the block is of a thickness to leave a place within the receptacle for a full deck of cards, while the opposite side 57 leaves a space within the receptacle for a half deck of cards. When a deck and a half of cards are to be used in the receptacle, the two blocks 53 may be slipped upon the end of the fanning bar 31 in a recess 58 provided therein, the blocks being illustrated in broken lines.

The bottom side of the base 20, as illustrated in Fig. 11, is provided with supporting legs 61 at the four corners and with further supporting legs 62 and 63 centrally thereof. Preferably the supporting legs are so disposed as to provide

spaces

64 and 65 for receiving portions of a deck of cards as play proceeds. The width 66 between the corner legs 61 is such as to receive a card when placed on the pack, with the length of the card extending to the left or right, as viewed in the figure. It will be further noted in the figure that the pivot 25 having the spring 49 thereabout may be enclosed in an apertured housing 67 molded in the base 20 to hide the spring from view. It will also be noted that the tops of the knobs 39, the receptacles 33 and the fanning bar 31 are all disposed in the same plane which, when inverted, sup ports the device, with the

legs

61, 62 and 63 extending upwardly, as illustrated in Figs. 11 and 13.

In Fig. 14, a further form of invention is illustrated, that wherein a cover 68 is secured by hinges 69 to the base 29, the hinges being similar to the hinges formed by the tongues 45 hereinabove described. An extension '71 is located at the front end of the base portion 20 so as to provide an area 72 in which the cards may be stored, as illustrated in broken line in Fig. 15. An upstanding wall 73 is provided on the extending portion 71, having a central finger 74 and projections 75 and shoulders '76 on each side thereof. When three decks of cards are employed, their edges will span the distance between the shoulders 76 and the central finger '74 will divide the three decks into two halves. When two decks are employed, the thickness will span the distance between the projections 75 so that the finger 74 can divide the two decks into two equal parts. In this manner, the cards may be divided into two equal packs, one for each receptacle. The top of the cover 68 is provided with similar corner legs 61 and central dividing partitions 77 to provide the two

areas

64 and 65 of a size to receive the cards. The

quadrants

23 and 24 have projecting dowels 78 rigidly secured thereto for limiting the movement of the cards after they are fanned from the end of the fanning bar 31, to thereby retain them in overlapped position. The dowels function in the same manner as the fixed block 29 illustrated and described hereinabove with regard to the structure illustrated in Fig. 1. If the block 2) were located in the same position as illustrated in Fig. 1, it would be within the area 72 and would prevent the cards from being stored therewithin.

In Figs. 15 and 16 -a movable stop block 79 is illustrated as being employed in place of the two dowels 78. The block 79 is mounted within a slot 81 of the base member 20 and is provided with an extending portion 32 containing a slot 83 in each side which receives the webs 84 each side of the slot 81. An aperture 35 is provided at one end of the slot 81 of a size to receive the portion 82 which has the slots thereof shifted over the webs 84. When the cards are being shufiied, the block is moved downwardly to the position illustrated in Fig. 15, and when the area 72 has the cards stored therein, the block 79 is moved upwardly, as shown in broken lines in the figure. In any of the forms of the device herein illustrated, the fanning of the cards occurs in a positive manner due to the tilted position of the cards when rested on the ledges 36 and the shape of the side surfaces 32, 34 and 35 of the fanning bar. The surface 32 aligns the cards squarely in the receptacles, as illustrated in Fig. and the surfaces 34 cause the entire pack to be bent in an opposite direction from the advancing movement of the sectors when the handles 39 are pulled toward the operator. The end surfaces 35 bend the ends of the cards a substantial amount to cause a snap action of the ends as the cards leave the fanning bar. This causes the cards to move into overlapped relation rather than into end-to-end abutting relation, as has occurred heretofore. The two parts of the deck are fanned simultaneously due to the interrelation of the corrugated or toothed edges 38, the amount of movement being limited by the

stop portions

41 and 42 at opposite ends of the mated portions. Filler blocks may be employed for changing the internal width of the card receiving receptacles to conform to the number of decks to be shuttled, the one of Fig. being pivoted at the top, the one illustrated in Fig. 9 being slipped upon the side Wall from the end thereof, while the one illustrated in Fig. 14 utilizes a vertical pivot 86 which permits the block to swing in extension of the wall 46 or to swing within the area of the receptacle for reducing the Width thereof. Feet are provided on the bottom of the device which produce a rigid support for the device when the cards are being shutfied, permitting the pivots 25 to extend downwardly a substantial distance from the under side of the base portion 20. By providing such a length to the pivots, the sectors :are maintained assembled on the base plate after the pivots drop within the apertures 43 thereof. The legs also function as card receiving areas when the device is supported on the tops of the knobs, receptacles and the fanning bar in inverted position from the position in which the cards are shuffled. Thus, a very simple card shufiling device is provided made from a minimum number of castings, three in number in the device illustrated in Figs. 1 to 13 inclusive, four parts being employed when the cover 68 is utilized, as illustrated in Fig. 14. Not only is a simply constructed device provided, but the device has a positive action so that rarely are the cards blocked by moving into endto-end relationship. While corrugated types of teeth are shown on the two sectors, it is to be understood that such teeth may be of any form which retains the two sectors in predetermined relation to each other and to the tanning bar. In Fig. 14 it will be noted that the length of the 'face 35 on the right-hand side of the fanning bar 31 is shorter than the face 35 on the left-hand side thereof, as viewed in the figure. This offsets the edge 88 rearwardly from the comparable edge on the left-hand side a fraction of the thickness of a card to avoid having a card from each receptacle leave the end of the fanning bar simultaneously. The same effect is obtained in the structure of Fig. 1

by having the receptacles 33 so interlocked relating to each other that a card from one receptacle passes from the end of the fanning bar a fraction of a thickness of a card ahead of a card from the other receptacle. In either of the arrangements, the cards are further prevented from moving into interlocked relation with each other which would interrupt the shuffling operation.
