'6 Claims. 1

This invention. relates to playing card shuffling devices and particularly to a shuffling device for effectively mixing two conventional decks of cards in a simple and rapid manner.

It has been found extremely difficult to effectively shuffle two decks of cards by hand and the effectiveness of the shuffle has been rather haphazard, since it is rather inconvenient to properly hold and riiile or otherwise mix two conventional decks, due to their bulk. Playing card games requiring two decks of cards, such for instance as the well known game of canasta, are largely dependent upon a thorough mixing of the cards and, since a rifiling of the cards results in a more effective mixing, the present invention has been designed in a simple and inexpensive manner to receive a divided double deck and, by a simple motion of a pair of rifiling arms, the two decks are thoroughly rifiled and intermixed.

The invention includes a tray wherein the divided double deck is manually arranged in angular relation with their ends contacting, a pair of riiiling fingers and a pair of swinging riifiing arms for exerting pressure upon the cards to be rifiied alternately from the rifiling fingers and fall within the tray more or less alternately with their ends overlapping, and a simple and novel means for pushing the riflled cards together.

An object of the invention is the provision of a device that will effectively rifile a double deck of cards, is cheap to manufacture, is simple in construction, is strong, durable, ornamental in appearance and is highly efiicient in use.

Other and important objects of the invention will be readily apparent during the course of the following description, reference being had to the accompanying drawings, wherein has been illustrated preferred examples thereof and wherein like characters of reference denote like parts throughout the several figures.

In the drawings:

Figure 1 is a front elevation of a device constructed in accordance with the invention,

Figure 2 is a plan view thereof,

Figure 3 isa vertical longitudinal-section, taken on line 33 of Figure 2,

Figure 4 is a transverse vertical section, taken on line 1-5 of Figure 1,

Figure 5 is an enlarged fragmentary front elevation, illustrating therifiling action,

Figure 6 is a fragmentary vertical longitudinal section through one end of the device, illustrating a modified form. of the invention, .and

Figure '7 is a transverse section, taken on line 7-? of Figure 6.

Referring specifically to the drawings and particularly to Figures 1 to 4 inclusive, the numeral 5 designates a base plate of generally rectangular shape having upturned and slightly outwardly inclined end flanges 6. Each flange 6 is provided with inwardly extending forward and rear wings l and 3, paralleling the base plate 5. At the junction of the flanges 6 and the base 5, fiat shoulders or ledges 9 are provided, for a purpose to be presently described. Extending vertically from the rear edge of the plate 5 and intermediate the length of the plate, is a relatively wide wall it having its upper terminus rearwardly flanged, as at H and preferably formed on an arc. The plate 5, flanges 6, wings I and -8 and the wall it with its flange Il, may be cast-as an integral unit, of metal, plastic or any other desirable material having sufiicient rigidity. The bottom of the plate 5 may be covered by a layer of felt l2, cemented or otherwise secured thereto.

'rojecting forwardly from the wall It], at a point adjacent to the upper end, is a bar [3, preferably formed integral with the Wall and having its opposite sides tapered downwardly, as shown, and the upper forward corner rounded. Fixed upon the bar It, adjacent tothe forward end, is a u shaped riflling element 14, having parallel legs I5 positioned upon opposite sides of the bar. The element It is rigidly held against movement on the bar l3, by a screw l6. As clearly shown in Figures 1, 3 and 5, one leg l5 terminates substantially flush with the lower edge of the bar, while the other leg 15 extends slightly lower, for a purpose to be described. The element I4 is substantially rigid, although it may be'desirable to impart a slight flexibility thereto.

Fixed upon the rear of the wall It], at opposite sides, are trunnion blocks l7, rotatably supporting the axially aligned ends iii, of a generally U-shaped card compressing frame It. The frame comprises a forward cross bar-20, integral with a pair of parallel arm portions 2 I. The arm portions 2| are bent in -a relatively wide are, at 22 and then are curved downwardly at 23 and extended at 24 and then bent upon themselves to form a preliminary card support and positioning arm, terminating in the ends Hi. The frame I9 is adapted to .be swung ina vertical plane from a position .of rest'at-the-rear of the base plate, to a position of rolling contact with the, surface of the cards.

The playing cards, .after being riflled, are positioned upon the surface of the base plate .5 in extended manner, with their ends overlapping. Means are employed to push the rifiled cards into a single pack, comprising a vertically arranged pusher plate 25, normally seating in a recessed rectangular opening 23, formed in one end flange 6. The lower end of the pusher plate 25 is provided with a bevelled foot portion 21. The plate 25 is moved toward and from the rifiled cards by a rod 28, having a sliding bearing in a tubular extension 29 of the flange 6. A hand knob 30 facilitates the shifting movement of the rod. The plate 25 is rectangular and its foot 2'! has sliding contact with the surface of the base plate 5. The plate 25 is maintained in proper travel position for engagement with the cards by the engagement of the foot 21 with the plate 5, thus preventing rocking movement.

In the use of the device, when it is desired to shufiie a double deck of playing cards, the cards are separated into two substantially equal piles. The compressing frame is swung rearwardly until the bar lies upon the surface of a table or other supporting medium. In this position, the extension 24 of the frame extends inwardly and overlies the base plate 5, as shown by dotted lines in Figure 4. The cards are then positioned in the device, with the outer ends supported upon the shoulders or ledges 9 and their upper or inner ends resting against the rifiling fingers !5, shown clearly in Figures 3 and 5. The cards are further supported by the extended portions 24 of the frame H). The operator then swings the frame l9 upwardly and forwardly by the bar 20, such movement causing the ends 25 to swing downwardly and rearwardly away from the cards. Continued forward movement of the frame I9 brings the arcuate portions 22 thereof into rolling contact with the upper surfaces of each pile of cards, pressing the cards downwardly and causing them to flex, as indicated in Figure 5. Continued downward pressure on the cards causes them to alternately snap from the terminal ends of the fingers l5 and, as they leave the fingers it, they fall downwardly to rest upon the surface of the plate 5, with their inner ends in overlapped position alternately. After the cards have been completely rifiied, the frame is again swung rearwardly to a position of rest and the operator then shifts the rod 28 inwardly, causing the plate 25 to engage the outer ends of the adjacent cards and shift them endwise for stacked engagement with the opposite pile. The completely riffled pile may then be removed by the operator by grasping them with his fingers and sliding them outwardly. It will be noted, that the forward wings i are sufficiently short to permit the sidewise shifting of the cards on removal. The operation may be repeated for a more thorough shufiiing of the cards if desired. After each operation, the parts are returned to their normal position. lhe bar 25 may be provided with a resilient sleeve 3|, to prevent scarring of a supporting surface, should the frame be swung rearwardly with any degree of force. While the device has been primarily designed to facilitate the shuffling of a double deck of playing cards, it will be apparent that a single deck can be riiiled with equal success, it being of course understood, that the deck would be divided into two separate piles as before.

In Figures 6 and '7, a modified form of push ing means has been provided. In this form of the invention, a base plate 32 is provided in its upper surface, longitudinally thereof, with a dove-tailed groove 33, slidably receiving a dovetail 34, carried by a movable end flange 35, corresponding to the end flanges 6 and also provided with the wings 36 and 31, corresponding to the wings I and 8. The end flange 35 carries a shoulder 38, similar to the shoulders 9. A stop plate 39 limits the outward movement of the flange. After the cards have been rifiled, the flange 35 is shifted inwardly to push the several cards into a single pile. The use of the shifting flange 35 avoids the possibly objectionable projecting rod 28, resulting in a more compact device.

It will be apparent from the foregoing that a very simple and novel device has been provided to effectively rifiie two decks of playing cards together. The use of the rifiling fingers is outstandingly novel with the two decks of cards supported in spaced relation to the surface of the base plate in a manner to cause their alternately released ends to overlap and fall upon the base plate. The presser frame imparts a downward flexing pressure upon the cards with a rolling action that progressively snaps the ends of the opposite cards of the two decks from the fingers I5, causing them to whip downwardly with their ends overlapping. The structure is simple and readily lends itself to economical manufacture from a variety of materials, such as metal or plastic. The device is shaped to avoid objectionable sharp corners and provides an ornamental device requiring a minimum of storage space and offers no objections as a part of every playing card kit.

It is to be understood, that the invention is not limited to the precise form shown, but that it includes within its purview, whatever changes fairly come within either the terms or the spirit of the appended claims.
