BACKGROUND OF THE INVENTION It has long been recognized among all classes of bridge players that some bridge hands are more interesting than others and that bridge is more enjoyable when interesting hands are encountered. Accordingly, numerous attempts have been made to provide systems for dealing previously played, interesting hands. There are numerous prior art disclosures of mechanical dealing mechanisms for dealing predetermined hands none of which has proved practical or commercially feasible. Somewhat simpler manual systems have also been proposed including at least one which has been commercially introduced with limited success wherein instructions for dealing a limited number of predetermined hands are printed on the backs of playing cards in a game where playing instructions call for revised bidding in accordance with the authors published recommendations for proper bidding before playing each hand. Duplicate bridge played with predetermined hands involves hand sorting in advance of play.
SUMMARY OF THE INVENTION The present bridge system provides for playing interesting newspaper" hands with the opportunity thereafter for comparing the original bidding and playing of the experts as reported in the newspaper columns. The system employs face coded playing cards, hand identi fying punched master cards, a manual dealing unit, and a sealed booklet having reproduced newspaper column descriptions of hands corresponding to the master cards.
A master card is placed under the deck of face coded playing cards in the dealing unit which has a mirror under one edge for viewing underside margin code marks of the lowermost card through punched holes in the master card indicating the hand to which the playing card should be dealt. As each playing card is dealt from the bottom through an escapement slit in the dealing unit hand identification for the next card appears.
A code line on each side margin of each playing card is symmetrically located in one of 52 distinctive positions. The master card has two columns of punched holes extending under one side margin of the playing cards. When a mark appears in the column nearest the dealer he deals to himself. When in the column nearest to his partner he deals to his partner. When in both columns he deals to his left. When no mark appears in either column he deals to his right.
Each master card has 13 punches in the nearest column identifying the dealer's hand; 13 differently spaced punches in the farthest column identifying his partner's hand; 13 further differently spaced punches in both columns identifying the left hand; and 13 unpunched positions corresponding to the right hand. After one or two hands are dealt the dealing pattern becomes automatic and almost as fast as a conventional deal. A large number of master cards corresponding to different newspaper column hands are supplied as part of the original set along with the sealed booklet having the corresponding newspaper bridge column experts comments on bidding and play reproduced which may be unsealed and referred to for comparison after the hand is played.
In a preferred modification of the system newly disclosed in the present continuation-impart application as illustrated in FIGS. 7l4, the use of standard data recording punch card hole spacing has been adapted with opening of tolerance requirements for coordinated registration with playing card code marks through the use of 26 longitudinal and four lateral hole positions instead of 52 longitudinal and two lateral.
The system contemplates subscription or other purchase of an unlimited number of master cards and booklets available from the vast reservoir of newspaper hands published over many years.
The foregoing as well as other objects of the present bridge system will best be understood from the following detailed description of a preferred embodiment with reference to the drawings wherein:
FIG. 1 is a perspective view of the various components of the bridge system;
FIG. 2 is a face view of several playing cards indicating code markings;
FIG. 3 is a perspective view of the dealing unit show ing a single card passing through the escapement slit;
FIG. 4 is another perspective view of the dealing unit taken'from another angle and illustrating the mirror system of reading through the master card;
FIG. 5 is a plan view 'of a single master card per se;
FIG. 6 is a sectional view taken along the line 6-6 of FIG. 3;
FIG. 7 is a perspective view of the modified dealing unit;
FIG. 8 is a plan view of such dealing unit;
FIG. 9 is a sectional view taken along the line 9--9 of FIG. 8;
FIG. 10 is a face view of two playing cards employing the modified code marking;
FIG. 1 l is an enlarged single master card strip for use in the dealing unit to identify one complete hand;
FIG. 12 is a reverse view (end over end) of the master card strip illustrated in FIG. 11;
FIG. 13 is a face view of a complete standard punch card adapted to identify three hands in three individual strips separable for use 1 in the dealing unit (with punched holes omitted); and
FIG. 14 is a reverse view (end over end) of the punch card shown in FIG. 13.
Referring to FIGS. 1 and 2 code marks 10 such as applied to the ace of diamonds are located symmetrically on each side margin extending in from the edge approximately of an inch within a normally blank area of the face border of a conventional deck of bridge cards. Code marks are provided in 52 distinct positions on the respective 52 cards comprising the deck within approximately a2 inch length along the side border with approximately a 0.040 inch relative spacing or pitch in line location. The code lines are preferably solid black on a white background and as heavy as possible short of overlapping which could lead to misreading under the various tolerances hereinafter described. In assigning code mark locations to the various card suits and values they are deliberately mixed on either a random or overlapping sequence basis so as to render impossible any specific or general evaluation from memorization and observation of mark location during dealing. In this connection the close 0.040 inch spacing is such as to render adjacent mark locations indistinguishable from general observations unaided by gauging means, which is an important factor in avoiding any suspicion of dealer knowledge of card values gained through observations of code mark locations.
As best shown in FIG. 5, the master card 11 is preferably punched with rectangular holes extending to the full width of the spacing or pitch so that two adjacent punches will leave no intermediate web, thereby assuring maximum visibility of any playing card code line in registration therewith when viewed in the mirror 12 located in a recessed pocket of the dealing unit 13 under the punched area of a master card positioned therein. The master cards are also preferably punched in two columns 14-15 on either side of a central dividing line 16 so as to provide four alternatives with respect to any particular card code line: (I) a single punch on the dealers side 14 indicating the card to be dealt to the dealer; (2) a single punch on the partners side indicating the card to be dealt to the partner; (3) punches on both sides 14 and 15 indicating the card to be dealt to the left or the west position (as shown by the indicia 17 on the top left rail of the dealing unit); and (4) no punch in either column indicating the card to be dealt to the right or east (as indicated on the right rail at 18).
Printed on the upper face of the master card is the number of the hand (82 as shown in FIG. 4) and indication of vulnerability of original players by the letters W-E or N-S or neither or both (as shown in FIG. 4).
In dealing the deck of cards is placed face down over a master card in the dealing unit and cards are dealt from the bottom of the deck through an escapement slit 19 at the lower end of a retaining gate 20 extending over the bottom of the holder 21; finger access to the bottom card being provided by an opening 22 in the bottom. Preferably, the bottom of the dealing unit incorporates a recessed pocket having a depth equal to the thickness of the master card to permit the deck to lie flush on top of same with the lowermost card aligned with the escapement slit which preferably has a depth of approximately 1 h times card thickness to facilitate card removal without hang-up or jamming of a second card. The master card and dealing unit preferably are provided with interengaging tabs 23 and recesses 24 positively retaining the master card against lateral movement with the bottom playing card during dealing. Endwise location of the master card is effected through registration of end surfaces 26 with side rails 27; the length of the master card apart from the projecting tabs 23 being exactly the same as that of the playing cards. A close free fit between the side rails and lowermost playing card is essential to avoid misalignment of master card and playing card which could result in a false reading. In this connection a draft or taper in the side walls is desirable to facilitate insertion of the deck while providing a close free fit for the bottom card.
In practice, it has been found that a code mark line width in the order of 0.020 to 0.030 inch with a pitch spacing of 0.040 inch and a punch slot opening of 0.040 X 0.100 inch for each column provides a highly visible combination while providing sufficient allowance for clearance and tolerance variations without any possibility of misreading a mark from an adjacent space. The dealing unit is preferably held directly in front of the dealer in a level position with the mirror reflection in full view of both eyes. In this position the code marks indicating the dealerss and partners positions are logical and the code of double marks for west and none for east is readily remembered and automatic after dealing a few hands at which time the speed of dealing is almost as fast as normal sequence dealing.
The master cards 11 are preferably selected at random from a book such as shown in FIG. 1 or cut for deal simulating the conventional cut of the playing cards, preserving the element of chance as to the hand to be dealt and the deal rotates from hand to hand in a clockwise manner as in conventional bridge. Each hand is bid and played under assumption of vulnerability corresponding to original players with scoring as in duplicate bridge. In producing the hand from a given newspaper column the dealers hand becomes south in the master card regardless of whether the dealer is north, south, east or west as reported in the newspaper column where the south hand is normally presented as the winning bid playerss hand regardless of who may be dealer. In this respect, vulnerability will likewise be restated with respect to the master card dealers hand as south in order to preserve the same conditions of play. It is of course obvious that in comparing play with that reported in the republished bridge column comparison would be made with reference to the actual hands rather than their designated positions of north, south, east and west which may or may not correspond depending on whether the dealer is south or otherwise in the reported hand. The book 30 containing reproduced newspaper hands preferably is sealed at its front edges 31 with an adhesive binder except for the top edge available for page reference corresponding to that of the master card. When bidding and play of a particular hand is completed it is intended that the players may then, if they desire, refer to the corresponding book page, slit open that page only and make any desired comparisons. It is intended that once a hand has been played the master card will be disposed of thereby avoiding any possibility of preview on the part of the host or other players. In this connection it will also be understood that additional master hands and books may be made available by subscription or otherwise and used with the original deck of cards and dealing unit so that the element of fresh hands may always be retained.
From the foregoing description it will be clear that the present bridge system provides a simple, inexpensive, convenient manual system for reproducing and redealing the interesting hands which have been reported for years in newspaper columns with the provision of an opportunity for comparison with the original bidding and play of the experts, if desired. The system retains all of the elements of natural play with the single exception that consistently interesting hands are provided. The deal passes successively from player to player. The element of chance as to who gets what hand is preserved by cutting for the next master card to be used. Secrecy is preserved and previews are rendered impractical by furnishing large numbers of hands with a sealed book describing each original newspaper hand .to be unsealed for comparison only after bidding and play are completed. The system contemplates a subscription opportunity for an unlimited number of additional hands for which master cards and sealed books are furnished and which can be used with the original coded playing cards and dealing unit fu rnished with the initial kit.
This system has been developed to avoid any possibility of memorizing or observing suit values of cards or any preview information regarding the hand by the dealer or other players. Code markings have been employed for the playing cards which are completely compatible with standard decks employing only side margins on the face which are otherwise blank on all of the cards of a conventional deck. Face rather than back markings are employed to avoid any possible implication of reading the card from the back by any opponent during dealing or play. 52 distinct code marked locations are employed with a spacing so close as to be indistinguishable from an unaided visual observation of location and are mixed with regard to suit and card values so as to render any information as to either, even of a general nature, unavailable from observation of code mark location during the dealing process. Only three hands are identified through punch marks in the master card so that there is no way of observing memorized code marks with reference to terminal punches in the master card (there being the possibility of up to 13 unpunched positions at each extremity of the master card).
Referring to FIGS. 7-14 the modified dealing unit, master card and coded playing card arrangement as illustrated, makes use of standard IBM System 3 data recording punch cards, FIGS. 13 and 14, adapted for multiple hand punching and separation into individual master card strips shown double size in FIGS. 11 and 12, each containing punched information necessary to identify one four-hand deal.
As shown in FIGS. 11 and 12, a standard 4 X 26 hole pattern is employed for hand identification. The holes punched in this standard data recording punch card are circular, spaced on a 0.0871 inch pitch in each direction, with a diameter equal to approximately one-half the pitch. The four hole positions a, b, c, d, extending progressively inwardly from the margin for each of the 26 longitudinal positions identify two different playing cards, one of which corresponds to the a and c hole positions on either side of the central dividing line 120 and the other of which corresponds to the b and d hole positions; likewise on either side of the dividing line 120.
A master card strip placed in the pocket of the dealing unit illustrated in FIGS. 7, 8 and 9 over the mirror 121 is supported on a ledge 122 with the left end of the strip as seen in FIG. 11 registering against the end wall 123 of the dealing unit and the right end confined by the ledge wall 124 shown in FIG. 8. The outer or lower edge of the strip as seen in FIG. 11 registers against the back wall surfaces 125 and the remaining inner edge against the shoulder 126 provided on the ledge 122 with recesses 127 accommodating tab projections 128 which may remain on the strip when separated for use. The pocket in the dealing unit is dimensioned to fit closely the four edges of a master card strip in order to minimize any clearance for shifting of the master card relative to the dealing unit.
With the master card strip positioned over the mirror 121, a deck of playing cards code marked as shown in FIG. is inserted face down so that one side edge of the lowermost playing card is superimposed over the master card strip. The dealing unit is provided with tapering walls to facilitate insertion of the deck but dimensioned at the lowermost card level to closely fit with a minimum free clearance assuring a coordination of playing card position relative to the master card strip. Each playing card is code marked with two side margin spaced code marks symmetrically arranged on either side, adapted to align in superimposed position with either a or 0 position punched holes 1300 in the master card strip as in the case of the 4 of diamonds or with the b and d positions 130b as in the case of the 4 of hearts. The two code marks on each playing card occupy a distinctive position in one of the 26 longitudinal spaces and in one of the two alternate pairs of the four lateral spaces to provide a total of 52 distinctive and unduplicated double mark positions corresponding to one of the 52 available pairs of punch card hole locations in the 4 X 26 hole pattern allocated to card identification.
The size of the code marks on the playing cards is preferably substantially equal to the hole pitch spacing of the holes in the master card which is approximately twice the diameter of an individual punched hole in order to provide a maximum tolerance in the relative location of superimposed punched holes and code marks without loss of full mark appearance in the mir-' ror viewing of the code mark through the punched holes. Thus, with a pitch and hole spacing of 0.0871 inches a relative shifting between master card and playing card from a nominal exactly centered position of approximately 0.022 of an inch in any direction can be accommodated without loss of hole mark registration for the corresponding punched hole and without any code mark registration for adjacent punched holes which could provide any chance for misreading.
The advantages of the modified. system illustrated in FIGS. 7-14 accordingly lie not only in the utilization of standard data processing hole spacing which permits the direct use of standard data processing cards in making master cards as will be subsequently explained, including available high volume rapid reproduction equipment for duplicating punch cards, but also in substantially doubling the manufacturing tolerances compatible with accurate reading relative to the dealing unit, card size, printing inaccuracies and master card as compared to the previously disclosed embodiment wherein 52 distinct longitudinal positions are allocated to approximately the same space along the margin on the playing card.
The same general dealing system as in the first embodiment is employed with a black dot appearing oh the out side only of the dividing line signifying a card to be dealt to the dealer; a black dot on the in side to the dealer's partner; a black dot on both sides to the dealers left; and no apparent mark to the dealer's right.
With reference to FIGS. 11-14, in adapting the standard IBM "System 3" datarecording punch card to the fabrication of master cards, the hole pattern available is in a rectilinear pattern of 32 X 18 as shown in FIG. 13 with a pitch of 0.0871 in inches in each direction. In the preferred embodiment, three complete fourhand deals are identified in three equal size strips which may be separated for individual use in the dealing unit and then discarded (or saved for repeated use if desired).
In processing standard blank System 3" IBM data recording cards, the size of which is represented in FIGS. 13 and 14 including the phantom line 134 at the bottom, the first step is to print the face of all supply cards with common page numerals as indicated in FIG. 13 in locations which maybe selectively punched to indicate a specific page number such as page 41 in FIG. 11. (Thus, any page from I to 9 may be indicated by a single punch in the right hand group of numbers and from 10 to 99 by a combination of two punches in left and right hand number groups.) On the reverse side shown on FIG. 14 only three dividing lines 200, b and c are printed. There is space at the top of the blank IBM cards 131 which of course may be used for printing any specific instructions or otherwise and only that printing specifically required for dealing purposes has been shown.
The next step in processing is to key punch one complete four-hand deal in the lower left 4 X 26 hole location space for three individual master cards 132a, l32b and 1320. Such punched holes, omitted in FIGS. 13 and 14, will involve a pattern spacing similar to enlarged FIGS. 11 and 12 but of course on a normal rather than double scale in size. Accordingly, whatever specific hand identifying pattern is punched will lie within the area indicated in phantom in each of the three strips shown in FIG. 13 which will overlie and be confined within the area of the mirror 121 as seen in FIG. 8.
In addition to hand identifying and page number punching, vulnerability if any is also indicated by punches 133; two horizontal or vertical punches indicating respectively opponents or dealers team vulnerability and three punches as shown in FIG. 11 indicating both teams are vulnerable. After all punching is completed for the three hands, the composite master card is employed for duplicating purposes, employing standard IBM duplicating equipment, in quantities sufficient to meet distribution requirements. Following production punching a suitably large number of different three-hand punch cards are collated for sales distribution. The cards are next processed to trimming and slitting operations wherein the lowermost phantom portion 134 is completely trimmed off and partial slitting along the three lines 135 is performed leaving only three tab connections 128 to facilitate player removal of individual strips 132a, b and c.
It is contemplated that the triple hand master cards will be packaged and distributed intact and for normal play will constitute a random distribution of interesting newspaper hands. In order to further simulate normal random play, it is contemplated that as the deal progresses clockwise from player to player each individual hand to be played will be determined by an opponent of the dealer cutting a stack of master cards to any random level from which the lowermost strip of the top card will be removed for insertion in the dealing unit. In order to avoid suspicions or implications of previous play, particularly where gambling is involved, it is contemplated that a fresh master card strip will be separated from triple hand supply card at the start of each deal and disposed of thereafter, since the available supply of newspaper hands is so great, and the production costs of the master cards so economical as to make possible a constant supply of fresh hands at nominal cost.
For special purposes such as duplicate bridge or instruction the master card strips may of course be reused at the players option. Nevertheless, it will be understood that an important factor in gaining general acceptance for the system lies in the provision of every possible means to avoid any suspicion of pre-view knowledge of the hand to be played. Thus, by using fresh master card strip each time, providing a sealed booklet with reprints of newspaper columns opened only after bidding and play are completed, and by employing a face coding system of card identification which avoids any possibility of reading code marks, as when printed on or punched through the back, acceptance of the system for general play and other purposes may be greatly enhanced.
With reference to the dealing unit illustrated in FIGS. 7, 8 and 9, it will be understood that the deck played face down, overlying a master card inserted in the recess pocket, will be supported on the top surface of the ledge 126 and the two corner supports 139a adjacent each of the escapement slits 139 establishing a level for the lowermost card along the line 138. With the deck in normal unbowed condition, the center support 137 is tapered along its upper surface as shown in FIG. 9 to provide a slight clearance at the end in the order of 1/16 inch against which a deck may be bowed by thumb pressure to assure lowermost card contact with the comer supports 139a facilitating bottom card dealing through the escapement slits without interference or hang-up. Since the cards need not be shuffled in use of this system, they are not exposed to distortion from the bowing incurred in shuffling and the use of escapement slits 139 in the order of 0.015 inch or 50 percent greater than card thickness has been found suitable to release the lowermost card freely while retaining the remainder of the deck in position. Slight practice results in accurate dealing almost as fast as conventional dealing.
The present invention is believed to incorporate novel patentable subject matter in the various sub combination elements of the system, including the master card and booklet which may be furnished as subscription or supplemental supply items, as well as the dealing unit and coded playing cards furnished as part of an original kit. Thus, while all elements cooperate in a single combination system, claims directed to novel and patentable subject matter of the sub combination elements are included along with complete combination system claims.
