The numeral 1t) generally refers to the chess machine as best illustrated in FIG. `1. Machine 10 is comprised of a housing 1l having a bottom 13, top` surface 15 and an interior 17.

Top surface 1S is provided with a square board 19 which consists of 64 individual squares, usually colored ivory and brown alternately. However, the board is described as having a White side and a Black side. For purposes of description, the numeral 21 indicates Whites side and the numeral 23 indicates Blacks side. Also for purposes of description, the board will be described by the algebraic notation system rather than the descriptive notation system. Viewing the board 19 from Whites side, the board 19 is arranged in eight liles from left to right which are designated by the letters a, b, c, d, e f, g and h respectively, and the eight ranks on the board from the lower to the upper side are denoted by the eight numbers 1, 2, 3, l, S, 6, 7 and 8 respectively. A square is named by use of both its tile letter and rank number, for instance, al is the square in the lower left hand corner of the board while h is the square in the upper right hand corner of the board.

Each player is provided with 16 men, all of the same color, White or Black. Eight of each group are called pawns while the other eight are called pieces. The eight pieces in each group are called: the King, the Queen, two Castles or Rooks, two Bishops, and two Knights. At the commencement of the game, each player places his 16 men on the board in a denite order. In the initial position, White would place the following men in the following squares: Queens Rook in al., Queens Knight in blt, Queens `Bishop in c1, Queen in dl, King in eli, Kings Bishop in fil, Kings Knight in g1, Kings Rook in h1, and the eight pawns are placed in a2, b2, c2, d2, e2, f2, g2 and 122 respectively. Black would initially place the following men in the following squares: Queens Rook in a8, Queens Knight in b8, Queens Bishop C8, Queen in d8, King in eil, Kings Bishop in f8, Kings Knight in g8, Kings Rook in 118 and the eight pawns are placed in a7, b7, c7, d7, e7, f7, g7 and h7 respectively.

Housing l@ is provided with a data card reader means 25 adjacent one end thereof. Data card reader means 25 can be of any suitable design but the embodiment of FIGS. l, 2, 6` and 7 are the preferred designs.

Card reader means 2S is provided with a tray 27 having a bottom 29 and upstanding sides 31 and 33. Sides 31 and 33 are provided with inwardly extending lips 35 and 37 respectively. A transparent hold-down 39` is secured to and extends between sides 31 and 33 as best seen in FIGS. l and 2 and has pointer or hairlines 4l at opposite ends thereof. A shaft 43 is rotatably mounted on tray 27 beneath bottom 29 and has a thumbwheel 45 secured at one end thereof, the upper end of which protrudes upwardly from the top of housing 11. Bottom 29 of tray 27 is provided with cut away portion 46 beneath hold-down 39 to permit a drive wheel 47 which is secured to shaft 43 to protrude from the upper surface of bottom 29. The numeral 49y designates a data card preferably having 8() columns of 12 bits each. Card 49 is inserted into card reader means 25 from one end thereof. Sides 31 and 33 guide the card while lips 35 and 37 hold the card down. Drive wheel 47 engages the underside of card 49 and the rotation of thumbwheel 45 causes drive wheel 47 to move the data card through card reader means 25. Drive wheel 47 and thumbwheel 43 are optional equipment in card reader means 25. A detent spring means 51 is secured to the bottom surface of bottom 29 of tray 27 and is adapted to successively eng-age bits in one of the rows of the card to position the card in card reader means 25. A plurality of photoelectric cells or light sensitive switches 53 are secured to card reader means 25 beneath cut away portion 46 and a plurality of lights 55 tare secured to the bottom surface of Ihold-down 39. It should be understood that photoelectric cells 53 would be positioned closer towards shaft 43 than is shown in FIG. 2. This is necessary to position cells 53 closer to the hairlines 41 for the proper relationship therebetween.

Housing 11 is provided with six auxiliary lights 57, 59, 61, 63, 65 and 67 at one end thereof. Housing 11 is also provided with a read switch 69 adjacent card reader means 25.

As previously stated, data card 49 is preferably provided with 80 columns each of which have space for 12 bits of binary digits. Card 49 has a top margin area '71 and a bottom margin area 73. Top margin area 71 is preferably divided into ten sub areas which are numbered 1-10. However, when additional cards 49 are needed for a particular game, the top margin areas thereof would be consecutively marked, that is, 11-20, 21-3tl, etc. Bottom margin `tarea 73 is divided into forty sub areas, each group of four having the same width as a sub area in top margin area 71. In other words, sub area No. in top margin area 71 would have four sub areas positioned therebelow in bottom margin area 73. The sub areas at the top margin area indicate the particular move to which the game has progressed. Each move therefore represents a from readout and a to readout for both White and Black as identified at bottom margin '73.

FIG. 4 illustrates the preferred circuitry for the machine but any number of different circuits can also be used. In FIG. 4, the reference numeral 75 designates a 115-120 volt power source which is series connected to a step-down transformer 77. Read switch 69 and a fuse 79 are imposed in the circuit between power source 75 and transformer 77. Transformer 77 is grounded at 81 fand a wire 83 extends to and is selectrically connected to 22 lights generally designated by the reference numeral 55. Each of the photoelectric cells 53 are imposed in the circuitry of FIG. 4 so as to be positioned opposite a light S5. As previously stated, card 49 is preferably provided with 80 columns of 12 bits. The card reader means is designed to read from awo adjacent columns at each readout. In other words, 24 bits can be read at one time but 22 bits are all that are needed for this particular design. Therefore, 22 photoelectric cells 53 are positioned beneath the 22 information bits in card 49 and 22 lights 55 are positioned abo-ve the 22 information bits in the card at each readout. If the card 49 has been punched in one of its bits, light will shine through the bit to energize the photoelectric cell therebeneath.

In FIG. 4, eight horizontal buss wires, generally referred to by the reference numeral 85, are electrically connected to the eight photoelectric cells 53 located adjacent the left side of FIG. 4. The eight horizontal buss wires 85 are electrically connected to eight vertical buss wires 87, as indicated in FIG. 4, which are electrically connected to the eight photoelectric cells 55 located at the bottom of FIG. 4. A pilot lamp 89 is connected between each junction of a horizontal buss wire and vertical buss wire as clearly shown in FIG. 4. Sixty-four pilot lamps are provided and a pilot lamp would be positioned beneath each of the 64 trauslucent squares in board 19.

Each of the 64 pilot lamps has a diode 91 connected in series to prevent unwanted current pathes from lighting additional pilot lamps. In FIG. 4, the numeral 92 generally designates various resistors which are provided in the circuit as illustrated. As seen in FIG. 4, the six auxiliary lights 57, 59, 61, 63, and 67 are controlled by six photoelectric cells 53 which are energized by six lights 55 respectively.

FIG. 5 illustrates the electrical circuitry of a modified form of the chess machine. In FIG. 5, it can be seen that the photoelectric cells and lights of FIG. 4 have been replaced by mechanical switches.

In FIG. 5, the symbol will be used to designate those elements which are identical to that which is shown in FIG. 4.

In FIG. 5, the reference numeral designates a 115-120 volt power source -which is series connected to a step-down transformer 77'. An optional read switch 69", optional on-oilC switch 93 and a fuse 79' are imposed in the circuit between power source 75 and transformer 77'. Operatively electrically connected to transformer 77 is a DC rectification means 120 which is electrically connected to one contact of 1l switches generally referred to by the reference numeral 110 and to one side of auxiliary lights 57', 59' and 61 by means of wire 83'.

A capacitor 122 is connected to rectification means 12@ and is connected to one contact of l1 switches 110 and to one side of auxiliary 110 and to one side of auxiliary lights 63', 65' and 67 by wire 124. Switches 110 are of the mechanical type and can be of any suitable design. For example, 22 terminals 115 (FIG. 6) could be positioned over the 22 information bits on the card and 22 spring loaded contact pins 117 could be positioned below the 22 information bits. When any of the bits are punched, pin 117 would make contact terminal 115 therethrough to energize a particular light. Also, 22 spring contacts 119 (FIG. 7) could be positioned at one side of the card, the switches being closed upon the spring contact pin extending through a punched hole in the card and engaging a terminal 121. It should be understood that the switches of FIGS. 6 and 7 are designated by the numeral 110 in FIG. 5. As previously stated, card 49 is preferably provided with columns of 12 bits. The card reader means is designed to read from two adjacent columns at each readout.

In FIG. 5, eight horizontal buss wires, generally referred to by the reference numeral are electrically connected to one side of the eight switches located adjacent the left side of FIG. 5. The eight horizontal buss wires 85 are electrically connected to eight vertical buss wires 87', as indicated in FIG. 5, which are electn'cally connected through 64 diodes and lights to one side of the eight switches 110 located at the bottom of FIG. 5. A pilot lamp 89' is connected between each junction of a horizontal buss wire and vertical buss wire as clearly shown in FIG. 5. Sixty-four pilot lamps are provided and a pilot lamp would be positioned beneath each of the 64 translucent squares in board 19.

Each of the 64 pilot lamps has a diode 91' connected in series to prevent unwanted current paths from lighting additional pilot lamps. As seen in FIG. 5, six auxiliary lights are generally designated by the reference numerals 57', 59', 61', 65' and 67 and are controlled by six switches 110.

With respect to FIGS. 1-4, the normal method of operation is as follows: Data card 49 is previously prepared by punching out certain of its bits. The machine is connected to the power source 75 and the machine is turned on by means of an optional switch 93.

Card 49 is inserted into data card reader means 25 as previously described. Thumbwheel 45 is rotated to cause drive wheel 47 to move card 49 into the card reader means due to its engagement therewith. Thumbwheel 45 is rotated until the rst white square in bottom margin area 73 is positioned under one of the pointers 41 and the sub area 1 of top margin area 71 is positioned under the other pointer 41 which places the card in its initial starting position.

White is the iirst player to move one of his men and he woud contemplate which piece or pawn should be initially moved. After the player has determined which piece or pawn to move, he will press the read switch 69 to compare his strategy with that of a previously played game which has been recorded on the data card. The closing of read switch 69 causes the lights 55 on one side of the data card 49 to be lighted. The light from the lights 55 will pass through any punched bits in card 49 to activate the photoelectric cells 53 therebeneath. For example, if Whites pawn on square e2 is the man which should be moved, the data card 49 would be punched so that the photoelectric cell in rank two and the photoelectric cell in file e are energized. The energization of the photoelectric cell in rank two would cause current to How through the horizontal buss wire 8S which is connected therewith. The energization of the photoelectric cell in .le e would cause current to flow through the vertical buss wire 87 which is connected thereto. The pilot lamp 89 which is positioned at the junction of the two beforementioned buss wires (square e2) will be lighted to indicate that the piece or pawn on e2 is the piece or pawn to be moved, or in other words, the from position. After having determined that the piece or pawn on e2 is the piece to be initially moved, White then determines where he should move the particular piece or pawn. White then turns thumbwheel 45 to cause the card to be moved to the next position which is the second white square on the bottom margin area. White then compares his strategy with the move recorded on the card 49 by again pressing read switch 69 to learn his to move. For example, if the piece or pawn on square e2 is to be moved to square e4, card 49 would have been punched to permit light to pass therethrough to energize the photoelectric cells in file e and rank four which would light the pilot lamp beneath the square e4. Black would then determine his from and to moves in identical fashion as did White. Data card 49 is also punched so as to energize the auxiliary lights at times to convey additional information to the players. The auxiliary lights are controlled directly by photoelectric cells as is obvious from FIG. 4. As previously stated, 22 bits in data card 49 are all that are needed for each read out. Sixteen bits select one or more of the 64 pilot lamps and six bits select one or more of the auxiliary lamps. The six auxiliary lights can be entitled: (1) Comment; (2) Check; (3) Good Move; (4) Bad Move; (5) Capture; and (6) Game End. The moves would be continued until the game ended. If the game required more moves than are on the data card 49, a second card would be inserted into card reader means 25, etc.

Detent spring means 51 accurately positions data card 49 over the photoelectric cells by simply successively engaging punched bits in one of the rows therein.

The embodiments of FIG. 5 operates like the embodiments of FIGS. l-4, the only difference being in the substitution of mechanical switches 110 for the photoelectric cells and lights -associated therewith. Additionally, if desired, read switch 69' can be omitted and the card reader means could be designed so that the mechanical switches 110 are normally open. The card reader means can be designed so that the upper portion of the traymeans which carries one contact of 22 switches 110 may be pressed downwardly to create contact between the opposing contacts of the switches 110 when the data card permits.

Thus it can be seen that the machine permits the players to replay games of the masters. Also, :the machine pernzits a player to learn the game of chess without constantly referring to books, etc. The machine simply indicates the from and to moves for each player through the used of a data card means. The machine conveys substantially all of the information to the players which could be conveyed to them by books, etc. without the constant reference to these books, etc. The players are continuously aware of the progress of the game due to the information contained on the top and bottom margin areas of the card, said information being aligned with the pointers 41.

Thus it can be seen that the device accomplishes at least all of its stated objectives.
