CARD-SHUFFLING MACHINE.

Specification of Letters Patent.

' Application filed .T une 7, 1915. Serial No. 32,523.

To all ywhom/15 may concern:

Be it known that I, GEORGE J. PERRET, a citizen of the United States, residing in Brooklyn, city of New York, county of Kings, State of New York, have invented a new and useful Improvement in Card-Shuffling Machines, of which the following is a specification.

This invention relates to machines for shuiiling cards used in playing games, the object being to thoroughly shuttle the cards, an operation usually performed by the hand, and the object is to guard against careless or imperfect work, to produce a complete and thorough mixed distribution of the cards, and to perform the operation with skill and expedition.

T have shown the best arrangement of mechanical means for attaining the desired end known to me, but I am conscious that skill and experience may improve on the mechanical arrangement and further limit the superficial area occupied bythe machine.

lThe accompanying drawings illustrate .the invention.

Figure 1 is a longitudinal section in normal position; Fig. 2 is a similar section showing an intermediate stage in a complete movement; Fig. 3 is a similar view showing the termination of a complete movement; Fig. 4 is a transverse section taken on the line 4--4, Fig. 3, looking in the direction of the arrows. Fig. 5 is a transverse section on the line 5--6, Fig. 1, looking in the direction of the arrows; Fig. 6 is a view on the line 5 6, Fig. l, looking in the opposite direction, and Fig. 7 shows details of construction.

There is a box of wood or metal a forming a complete inclosure; there is a door 32 hinged at 33, through which the complete pack of cards C is introduced, to rest upon a slide b, which reciprocates upon slideway c. lVhen the slide I) has been carried to its extreme right hand position, Fig. 3, cards C drop down and rest upon the slideway 0,' the slide .7) projects above the slideway c as indicated in Figs. 1 and 2 and the extent of that projection determines the number of cards to be removed from the bottom of pack C. Upon the return movement of the slide I), cards are separated from the bottom of the pack and moved down the slideway h into a second receptacle f, where they rest upon a reciprocating device; as soon as the divided section of cards has reached this point, two vertically reciprocating Wires 53, 54, engage and hold them, while the reciprocating device 22 returns to its normal position; upon the succeeding movement, another section of cards 1s removed from the bottom of the pack, passes down the slideway h, the fingers rise, the reciprocating element 22 moves the second division of cards up against the preceding division, the iingers descend and retain the section so separated, and the cycle of operations is repeated, until the-pack has all been transferred in its changed, or shuffled sequence.

Referring to Fig. 1, the device for separatlng a plurality of the cards C from receptacle in which they are normally placed, consists of the sliding wooden section b, traveling on the slideway 0,' the cards are retained in position by side pieces 27 and 28, and the hinged cover 32. A spring s iixed at one end to the part 34 and at the other end to a pin projecting from the bottom of the slide serves to return slide I) to its extreme left hand position, where it is stopped by a projection w, engaging the partition 2S. The second receptacle 22 is located below the first receptacle, and the cards pass by gravity through the passage h from one receptacle to the other. The receptacle f slides on the bottom of the box a, the bottom portion 20 is a thin board having a long slot 2G, and its movement is retarded by a friction device composed of a Washer 'w engaging its upper surface; washer fw is pressed downward by a helical spring 36 on a pin 3S, and a-plate 37, with the washer w, slide on pins 39. 22 is a reciprocating vertical plate moving on the surface of the part 20, and there is a platform 23 .fixed to the part 22 which receives the division of cards upon its arrival at the bottom of the passage l1.. At this time the divided section of cards rests upon the platform 23 and rests against the wall 35. There is a door G4 hinged at G5, which door controls accesskk to the shufiied pack. To remove the cards,

`the door 64 is lifted and the reciprocating receptacle 21 is drawn out, the cards re-l Fig. 4, which in one position project downward far enough to pass through a slot in the reciprocating device 22. A cross-wire connects these two fingers and a vertical finger 52 projects through a fixed guide n. and the fingers travell in a fixed transverse guide o. For the purpose of connecting the manually operated motor device, to be described With these vertically reciprocating fingers, I provide a shaft located outside the box; this shaft mV is ournaled at 48 and 49. There is an arm 51 of wire pivoted at 151, see Fig. 4, which engages the loop of wire terminating in the vertical member 52. The wire 50 projects through a slot 56 in the side of the box, and this wire is firmly fixed to the shaft m, and its free terminal engages the arm 51, so that when the arm 50 has its free end elevated by the partial rotation of shaft m, it elevates the free end of the Wire 51 and this lifts the lingers 53, 54. l The introduction of the pivoted arm 5l and its engagement with the arm 50 is a mechanical device to increase the extent of movement of the fingers, as compared With the extent of movement of the free terminal of the arm 50. The details of construction of this shaft fm, and the arms 50 and 51 are clearly shown in Fig. 7.

A manually operated motor device 1s provided to operate the reciprocating parts and maintain the regular sequence of operation. This consists of a transverse shaft d journaled in the walls of the box, and havlng an exterior handle or crank e. On this shaft is a radially moving member 11 which engages with the fixed projection 10, fixed to the bottom of the reciprocating slide b. The projection 10 is mechanically connected with the reciprocating device 22 by means of a link 12 pivoted to the part 10 at 13, and a link 14 is pivoted at 15, links 12 and 14 are hinged together at 16, and a link 17 is hinged to 14 at 18 and to the reciprocating device 22 at 24. There is a cam z' engaging the -lever 7c which lever 7c is pivoted at 41 and has a projection 40 engaging the cam surface of i. The opposite end of lever c is hinged at 44 to a link 45, which in turn is hinged to an arm 47, fixed in the shaft lm and hinged to link 45 at 46. When the crank arm e is rotated, projection 11 engages projection 10, this forces the reciprocating device b against the action of spring s withdrawing it from under the pack of cards C, the cards drop down the distance measured by the dotted line and the surface of the device b, Fig. 1; simultaneously with this movement, the link connections 12, 14, 17. is straightened out to a certain extent and the reciprocating device 22 with the platform 28 is moved under the passage h and coincidently with this the cam i operating on the projection 40, tilts lever c, which rotates shaft fm, to a certain extent. This elevates the free terminal of arm 50, which in turn elevates arm 51, and the fingers 53, 54, are elevated; the part 22 is now moved up into contact with the subdivision of cards in the receptacle 21, while the fingers 53, 54 are elevated out of engagement with said cards. As this movement of rotation of crank arm e is continued, the reciprocating part b and 22 return to their normal position, while the fingers 53, 54 descend and retain the division or divisions of the cards which have been transferred to the lower receptacle. rIhis rotative movement is repeated and the cycle of operations dcscribed is repeated, until the cards are all transferred from one receptacle to the other. There is provided a receptacle for an extra pack of cards C. This consists of a holder 58 pivoted at 59; the holder 5S is forced outward into the position shown in Fig. 2 by a spring 60. The holder 58 is normally held in a compartment 57 having a door 61 pivoted at 64, which, when closed, forces the holder 5S back into position, while the door is retained in its closed position by a catch 63.
