FIG. 3

IN VENTOR HJALMAR EMANUEL SJ6STRAND MVM ATTORNEYS United States Patent 3,147,978 PLAYING CARI) DEALING DEVIEES Hjairnar Enianuei Sjiistrand, Saxdalen, Sweden Filed Jan. 14, 1958, Ser. No. 708,954 Claims priority, application Sweden Jan. 16, 1957 17 Claims. (Cl. 273-149) The present invention relates to a device for mechanically dealing or dividing a deck of playing cards into a predetermined number of hands or groups.

It is a primary object of the invention to provide a playing card dealing device in which the individual cards of the deck of cards are projected into various compartments at a comparatively high speed which is independent of the speed of the driving member of the device, ensuring a satisfactory operation even at low speeds of the driving member.

The invention is applicable in the first instance. to handdriven playing card dealing devices, but it may be applied to advantage also to devices which are motor-driven.

The invention will now be described by way of example having reference to the accompanying drawings illustrating diagrammatically different embodiments of the. invention.

FIGURE 1 shows in side view and partly in section part of a first embodiment of a device according to the invention.

FIGURE 2 is a plan view corresponding to FIGURE 1.

FIGURE 3 is a continuation of FIGURE 1 towards the right and shows a number of compartments into which the cards are projected in succession.

FIGURE 4 shows in side view and partly in section part of a device according to a second embodiment of the invention.

FIGURE 5 is a diagrammatic side view of a modified arrangement for establishing communication between the magazine for the deck of cards and the various card receiving compartments.

FIGURE 6 is a partial sectional view showing a modified card gripping device.

Referring first to FIGURES 1 and 2, the reference numeral 1 denotes a frame and the reference numeral 2 a magazine for a deck of cards. The magazine has the shape of a box which is open on top and at one of its short sides and is so dimensioned that the playing cards will fit into the box with a certain lateral clearance. The reference numeral 6 denotes a moveable bottom or platform secured by means of a screw 5 in horizontal position to a tube 4 guided for vertical movement in an outer fixed tube 3. Disposed within the inner tube 4 is a helical spring 8 dimensioned to lift the deck of cards 7 and press the uppermost card against two limit rollers 9 journaled on a horizontal pin 10. The spring 8 is furthermore so dimensioned that its expanding pressure decreases at such ratio according as the cards 7 are projected from the magazine that the contact pressure between the cards and the limit rollers 9 will remain substantially constant independently of the number of cards held for the moment in the magazine.

A driving shaft 11 is provided with a hand crank 12 at one end and with a gear wheel 14 at the other end. The gear wheel 14 is in mesh with a smaller gear wheel 15 secured on a driven shaft 16, the gear ratio being 1:4. On the driven shaft 16 is also secured a small flywheel 17 by means of a pin 13. Adjacent the flywheel 17 there is freely journaled on the driven shaft 16 a cup-shaped card projecting drum 19 of light metal, the open side of said drum facing the flywheel.

The flywheel 17 and the card projecting drum 19 are coupled together by means of a helical Spring 22 which is secured at one end to a pin 23 in the flywheel 17 and at 3,1d'i,'i8 Patented Sept. 8, 1964 the other end to a pin 24 in the drum 19. For limiting the angular displacement between the flywheel and the drum there is provided on the flywheel an axially extending pin 20 which projects through an arcuate slot 21 provided in the end wall of the drum near the periphery thereof.

Provided on the outside of the end wall of the drum 19 is a Wedge-shaped segment 25 with which cooperates a brake-block 26 of friction material secured to one end of a blade spring 27 the other end of which is secured to the frame 1 by means of a screw 28 and a fastener 29. The blade spring 27 is so positioned that its brake-block 26 is free from the drum except when the brake segment 25 passes under the brake-block, its thinner end leading, the braking effect increasing successively with the increased pressure of the blade spring against the brake block. Due to the braking of the drum 19 the drum will be caused to lag behind the flywheel a maximum angle, as shown in FIGURE 1, against the action of the coupling spring 22, tensioning the coupling spring further.

Secured to the circumference of the drum is a projecting segment 30 of frictional rubber, the outer radius of said segment being such that the segment reaches somewhat below the level of the underside of the limit rollers 9 when the drum takes up the position shown in FIGURE 1, i.e. the projecting segment 39 will take up its lowermost position in gripping engagement with the uppermost card 7 at the very moment when the brake segment 25 slides 011? the brake block 26. When the braking of the card projecting drum 19 thus suddenly ceases, the tensioned coupling spring 22 will rapidly pull the drum forward to its other limit position, in consequence of which the drum 19 will increase its peripheral speed during the last stage of the feeding-out movement of the uppermost card in the deck of cards, so that the said card is projected from the magazine 2 at a high speed also in case the hand crank 12 is turned slowly.

The reference numeral 32 denotes a guide member for the projected card, the said guide member being turnable at one end around a horizontal pin 34- and being supported at its other end by a vertically disposed helical spring 36 tensioned between a pin 37 in the frame 1 and a point 38 at the upper side of the guide member. A link in the shape of a blade spring 39 couples the guide member 32 to a follower 41 which is swingable about a pin 40 and presses against a cam disc 42 secured to the driving shaft 11. The cam disc 42 is shown as having four sections, each section comprising a comparatively short eccentric portion and a comparatively long concentric portion so that on rotation of the driving shaft 11 the guide member 42 will be moved stepwise stopping for an instant right opposite one of four fixed guide paths 33 each time a card 7 is projected from the magazine 2.

In the embodiment shown, the fixed guide paths 33, which are made of polished plate of light metal, are somewhat narrower at their inlet and outlet openings, their middle portions being wider in a vertical direction for the purpose of decreasing friction while retaining a certain guiding effect. The fixed guide paths 33 each opens at the upper edge of a corresponding pocket or compartment 44 the bottom of which forms an obtuse angle with the guide path, causing the rapidly moving card to slide with its front edge against the lower guide surface obliquely upwards, causing its rear edge on account of the resilient bending of the card to move downwards so that it bounces against the rear wall behind the outlet opening of the guide path and sinks to the bottom before the next card is received.

As shown in FIGURES 1 and 2 the same device may be used alternatively for dividing the deck of cards either into four parts, as already described, or into six parts. For that purpose there is secured on the shaft 11 by means of a pin 46 a gear Wheel 45, and on the shaft 16 by means of a pin 48 a gear wheel 47, the gear ratio in this case being 1:6. An extra cam disc 49 is also secured to the shaft 11. Said extra cam disc has six sections of 60 each, the four innermost sections having the same radii as the four sections of the cam disc 42, whereas the fifth and the sixth sections have correspondingly larger radii. The extra cam disc is secured in such a position on the shaft that the beginning of its first section is located exactly opposite the corresponding point 42a on the cam disc 42. The hand crank 12 is so secured to the shaft as to extend in the same radial direction as the inner portion of the cam disc. It follows that when the hand crank is directed downwards it can be moved together with the shaft, the cam discs and the gear wheels in an axial direction to cause the gear wheels 45 and 47 to mesh. The gear wheels 45 and 47 will mesh before the gear wheels 14 and 15 unmesh, and vice versa.

Also the embodiment shown in FIGURE 4 comprises a spring which gives the card projecting member a rapid movement in the card projecting direction. In the embodiment shown the uppermost card in the deck of cards placed in the magazine is gripped by a small downwardly concave suction cup of soft rubber. Vulcanized to the uppermost portion of the rubber cup and extending upwardly through a hole near the end of a blade spring 57 is a small screw bolt 56, the screw bolt being secured to the blade spring by means of a small ball-shaped nut 58. The portion of the blade spring carrying the rubber cup 55 extends substantially horizontally. An extension of the blade spring is bent through an angle of about 90 around a metal bushing 59, to which the spring is secured, the extension extending upwardly for a distance of about 1 centimeter. Secured to the upper end of the extension is a small weight 66. The bushing 59 is journaled on a horizontal pin 61 secured to the lower end of a card projecting rod or arm 62, said arm being made of light metal plate and being U-shaped in cross section. The card projecting rod 62 is turnably journaled at its upper end on a horizontal pin 64 secured by elements 65 to the front side of a frame 66.

The frame 66 has the shape of a box open at top and bottom and provided at one of its corners with a cylindrical sleeve 67 for receiving a carrying pipe 69 extending from a bottom plate 68. Provided at the front side of the frame 66 is a horizontal projection 70 the outer portion 71 of which is directed at right angles downwardly and provided with a pin 72 to which is secured one end of the card projecting spring 73 the other end of said spring being secured to the card projecting arm 62 by means of a pin 74. Near to the upper end of said rod or arm 62 the two side plates of the arm are shaped to form a projecting nose 75 at the point of which a narrow roller 76 is journaled on a pin 76a.

Secured on the driving shaft 77 is a symmetrical fourarmed cam member 78. With said cam member 78 cooperates the roller 76 on the card projecting rod 62, said roller being pressed against the eccentric surfaces of the cam member by the card projecting spring 73. After said roller during rotation of the shaft has been lifted to the outer extremity of an arm of the cam member 78 and thus has swung the card projecting arm 62 to its starting position while tensioning the spring 73, it suddenly slides off the point permitting the spring 73 to pull the car projecting arm 62 rapidly to its other limit position.

On account of the inertia of the weight 60 said weight will cause the blade spring 57 to swing on its axis each time the card projecting rod 62 changes its direction of movement. This happens in the two limit positions shown at 62a and 62b in FIGURE 4. In said figure is also shown the changed positions of the gripping memher 55 with respect to the uppermost card in the magazine 79, the gripping member being pressed against the card at the rear end position 62a and being caused to release the card at the front end position 62b. In the latter position the card has obtained a very high velocity in a direction out through the guide path 86 to the card receiving compartments.

It should be noted that the gripping cup must not necessarily be positioned at the lagging end of a blade spring link or the like, but it may also be positioned at the leading end. In such a case the weight 60 must be eliminated or arranged in other manner than shown.

The arrangement shown in FIGURE 4 for successively directing the cards to different compartments consists of a spiral shaped cam 80 provided on the driving shaft 77, an angular lever 81 swingably mounted on a pin 82 at the front side of the frame 66. On a connecting rod 83 secured to the free end of the angular lever 81 is provided a helical spring 84 adapted to press the connecting rod upwardly. At its lower end the connecting rod is pivotally secured to a guide member 86 swingably secured at the outlet end of the magazine by means of a pin 85. Said guide path or member is intended to cooperate with four fixed guide paths leading each to a corresponding pocket or compartment, for instance of the kind shown in FIGURES l to 3. The driving shaft 77 is normally provided with a hand crank, not shown. Alternatively, a small electric motor may be used as a driving source.

In FEGURE 5 is illustrated another embodiment of the device for successively guiding the projected playing cards to various pockets or compartments. The swingable guide member 32 or 86 shown in FIGURES l and 4 is here substituted by a plurality of guide paths 87 combined to form a unit and journaled by means of a pin 88 in posts 89 rising from the bottom plate. At the outlet from the magazine is arranged a fixed mouthpiece 90 provided with a narrow slit-shaped month which guides the rapidly projected cards into the inlets of said guide paths and pockets. The desired swinging movement of the unit 87 may be obtained for instance by means of the connecting rod 83 shown in FIGURE 4 or the blade spring 39 shown in FIGURE 1.

In FIGURE 6 there is shown in cross section and on 1 an enlarged scale a modified embodiment of the gripping member at the lower end of the card projecting rod 62 of FIGURE 4.

For obtaining a higher suction power in the rubber cup 55 than the one resulting from the contact pressure caused by the weight 60, FIGURE 4, there is provided a small rubber bladder 91 enclosed in a small box 92 in the card projecting rod 62, rectangular openings 93 and 93a being provided at the rear and front sides of the box.

At the bottom of the bladder is provided with narrow rubber hose 94 leading through opening 95 out from the box and extending to the inside of the suction cup 55. Both ends of the rubber hose are glued to the respective rubber members. In FIGURE 6 the weight 60 and part of the blade spring are cut away to illustrate the above described details more clearly. At the upper edge of the card magazine or at an extension thereof are secured two substantially equal abutments 96, only one of said abutments being shown. The effective part of each abutment 96 is adapted to pass through the opening 93 or 9311 to partly compress the bladder 91 when the card projecting rod approaches one of its limit positions, as shown in FIGURE 4. In this manner part of the air is driven out from the bladder 91 before the rubber cup 55 is moved into engagement with the uppermost card 7. When the card ejector rod continues its movement forwardly in its card projecting direction the bladder is released from pressure and will expand resiliently causing an increase of the vacuum and a more secure grip between the cup and the card. Immediately before the card projecting member 62 has reached the limit position shown in dotted lines at 62b in FIGURE 4 the other of said abutments, not shown, will enter through the front opening 93a of the box 92 and compress the bladder 91 very rapidly, causing the suction in the rubber cup 55 to cease and enabling the cup to be lifted from the card in the manner already described.

As will be easily understood the playing card dealing devices illustrated and described may be used not only for dealing the cards in the deck of cards to the participants of a card game but may also be used for mixing the cards in the deck. Such mixing may be effected by placing the various groups of cards obtained by operating the device upon one another in an arbitrary order and place the cards in the magazine anew, whereafter the device is operated as before.
