CARD DEALING DEVICE Filed Jan. 6, 1932 2 Sheets-Sheet 2 EicharaCSmilZ Patented May 14, 1935 UNITED STATES:
My invention relates to devices for mechanically dealing cards-that is to say, dividingv a previously shuflled deck by delivery of the cards in regular succession into a plurality of groups. The device should be distinguished from shuflling machineswherein it is the intention to distribute cards differently throughout a deck by distributing them irregularly into one or several groups formed from the original deck, and then consolidating these groups, if more than one are formed.
It is an object of my present invention to devise a machine of the character indicated which can be inexpensively constructed, to the end that it canbe sold at a price attractive to the large group of those who play for amusement, and can be built in large quantities.
It is an object, then, to devise such a machine byrmeans of which the cards are delivered one by one, and which has means for positively intercepting-and holding back cards inexcess of the one which is intended to be delivered.
It is a further object to devise a receiving device for employment in such a dealing machine, and to provide means for presenting the several compartments in succession in position to receive the successively delivered single cards, so that; for instance, four hands maybe dealt, the cards being delivered in recurring succession to the several compartments, ready for play. 7
Other objects, and more especially such as deal particularly with the mechanical details of my invention, will be best understood as thisspecification progresses. I
My invention comprisesthe novel parts, and
. the novel combination and arrangement thereof,
as shown in the accompanying drawings, described inzthespecification, and as will be more particularly: defined by the claims which terminate-the same.
In the accompany ng r wings I have shown my invention embodied in a form which at present is preferred by me, it being understood'that the principles thereof may be otherwise embodied, within the scope of the claims.
Figure l'is a plan view of the complete machine,
and Figure 2 is a longitudinal vertical section therethrough on the line 22 of Figure 1.
Figure 3 is a view similar to Figure2, showing parts in a position assumed during the delivery of acard, and Figure 4'is asimilar view, taken on the line 4'4.of Figure 1, showing a further stage in theldelivery of a card.
.gure 5 isa transverse vertical section through themachineon the line 5-5 of Figure 1, and
Figure dis a cros's section throughthe hopper on the line 6-45 of Figure 1.v
Essentially the device comprises a hopper to receive a deck of cards, a seriesof compartments to receive the cards insuccession, means to move the compartments so that the successively presented cards are received in; difl'erent compartments, in regular rotation, andmeansto handle the cards, first to project them from thelhopper,
moving the-lowermost-card first, then insuring that only thelowermost card will be further advanced, then engaging and feeding forward this lowermost. card for, delivery to the compartment then presented, Theseveral parts are timedtogether soas to accomplishthe end in view, which isthe distribution of vthe' deck of cards, or any portionthereof, into a given number of hands, eachof anzequal-number of cards. The machine may be designed to deliver any number of hands, within reason, and may deal out the entire deck or any portion thereof. I Let-usassume that itisintended that. the ma:- chine shall deal four bridge hands from a deck. Aureceiving box I is divided. into a; plurality; of compartments ll,- 12, l31and Hi. In orderto support this box fromthe frame. 9, or a bracket 9|, upstanding therefrom, I may provide an arm or arms I!) pivotedat. l5 atsuch adistance from theentrance. to the compartments ll, I2, 'l3
and. M as tov flattenthearc. of swing thereof to a considerable extent,,and to lessen the size of a cam l whichmoves the same, as will be explained hereafter. Thebox hasa pin l6 pro jecting therefrom between the; entrance tothe compartments and the pivot point l5, for engagement withthis cam.
At the oppositeend'ofthe frame isjsupported the hopper, and as illustratedin Figure 6, this maycomprise a rectangular frame 2- having the cover- 20with flanges 21 in whichthe deck may bereceived when the cover. is removed, and which may be then inverted. within the hopper "2. The hopper. is providedwith flanges 22 at its lower sidetosupport a deck of cardsD. A weight 23, I with ani als-24. projecting through. the top 20, may be employed to presslthe cards down to" the bottom of-the hopper. The bottom of the hopper otherwise is open, and the hopper, has a slot 25 at the bottom of'one. side through. which it is intended that single cards shallibe. discharged. t
T M P) 2 Y grip between this card and the one above it, and will cause the same to be withdrawn from beneath the deck, and to be projected through the slot 25. Movement of the platform may be accomplished in various ways, for instance, by means of a downwardly projecting fin 32 having a vertical slot 33 in which is engaged a crank pin 43 upon an arm 42, which arm is rotatableby means of a crank handle 4 (see Figures 1 and 5). Both the armAZ and the crank handle 14 are secured upon-the shaft 4|. J. "i.
Likewise secured upon this shaft 4| is a drive wheel such as the gear 50, through a chain drive, indicated at 51, a hold-back roller a shaft 52, which may be supported forgslight vertical movement in frame, and which in such upward above the plane of C by means such as to rotate than the tendency of-the 'r'o'llerf5 to move it or' hold it back,=but if a card,'-such as the card in Figure 3,'rests upon a lower card'C, the frictional' grip on the under-surface of the upper card Cfwill be less than the grip of the roller tending to hold it back, and consequently only the lowermost card in eachinstance will be moved past the hold-back roller'5.
Suchmovementof the roller S'intoengagemerit v rith the cards may be I accomplishedin various -'ways, for instance, by providing a nose 35 upon the fin 32, this'nosebeing engageable with an inclined cam-member 55"ccnnected by an arm 54 to the shaft' 52. These members-are so positione'd' that the cards' uponthe platform will have their leading :edg'esadvanced beyond the roller 5 before theroller isfbrought"down into "engagement ther'ewith, for ifthe roller were to engage with the leading edge of afsi'ngle card C, the engagement with the edge might: be sufficient in some-cases to'overcome the frictional grip of the platform 3 :upon-the' card,'and it would be thus heldback and the dear would be incorrect. l a 1 After the cards have been thus-projected',-and excess cards held back; 5 the lowermost 'card- C will be passed bythe latter portion of theplatforms advance between rollers 6 andtll which act as feedrollers to complete the withdrawal of the card from'the hopper and from-engagement with the platform and"hold -back roller. The roller 6 may be frictionally engaged by the roller 5 to cause rotationof the roller 6,- and the rollers 5 and 60 may befrictionally engaged with each other, as is common infeed"rollers."-'- LIn order to present the-several compartments H, l2,l3 and 14 into such pos'itio'n'as toreceive a card advanced between the feed-rollers 5' and 60,,Imay: provide cam means,- generally indicated at s'i,upon a shaft-l0, this-cam means being formedfor engagement with the pin=' l6, previ"- ously referred to,'to advance the -box -lS step byfstep from'one position" ;to1an0ther -through' a recurring cycle, and thus I have. shown the sevwhich is connected 5. This roller is secured upon sion by turning the vertical slots 95 of the caseis' yielding'ly held movement; of, a card 1 3 the spring 53. This holds the" roller 5 normally above the plane of move-- It is believed that the sealer of use of my device will now be apparent. Cards are placed in the hopper 2, are
delivered one by one into the compartments ll, l2, l3 and M in succescrank handle 4, and when the dealing iscompleted the several hands are removed from the end of the box I (see Figure 1).
