8 Claims. 1
The present invention relates to a game recorder.
More specifically, this invention concerns an apparatus designed to keep a complete record of a game such as chess or the like, every move by each player being recorded as well as the interval of time between successive moves. The apparatus is particularly suitable for use in chess playing but may be modified, or even simplified within certain limits, for the recording of other games played on a limited playing surface of chequered or similar design.
The main object of the present invention is to provide an apparatus capable of recording, in a game wherein a plurality of game pieces are moved about a limited playing area according to standardized rules, the actual position of each piece at each move.
It is another important object to provide apparatus of the character described which records also the interval of time which has elapsed between successive movements of the pieces.
Another important object of the invention resides in the provision of apparatus of the type set forth above which is especially suitable for recording purposes in the playing of chess, and
thus advantageously usable in chess competitions or tournaments where it is often necessary to review the games or to ascertain that each player has obeyed the rules.
Yet another object resides in the provision of I apparatus of this nature wherein the actual position of all pieces in the playing area are recorded, automatically and preferably on paper, as each movement is completed. Thuseach recording on the paper is a complete picture of the game at that movement.
Still another object is to provide apparatus of the type described, which is practical, fool proof in operation, and is capable of embodiment in an attractive, compact unit-a unit which may resemble a desk including a chess board on top and at opposite sides of which two opponents may be seated conveniently for play.
And still another object resides in the provision of apparatus of the character set forth which is of simple, durable design and whose operation may be understood by any intelligent individual.
Other objects and advantages will become apparent or be further pointed out in the description to follow.
As an example, and for purposes of illustration only, a preferred embodiment of my apparatus as designed for the recording of chess Figure 1 shows a perspective view of the apparatus as enclosed in a table or desk, looking down towards the playing surface thereof;
Figure 2 shows a plan view of the apparatus of Figure l with the top-enclosing covers removed;
Figure 3 shows a longitudinal section through the apparatus;
Figure 4 shows an enlarged view of part of Fig. 3 illustrating some features of the apparatus in greater detail;
Figure 5 shows a, detail similar to a portion of Fig. 4'at another point of operation of the apparatus;
Figure 6 is a transverse elevation view, somewhat diagrammatic in representation, illustrating the time-interval recording mechanism;
Figure 7 shows a detail sectional view, longitudinally of one of the positions of the playing area, indicating when in inoperative position the members beneath the playing surface adapted to be actuated by the chessman;
Figure 8 is a view similar to Figure 7 with a chessman occupying the position;
Figure 9 is a detail sectional elevation, longitudinally through the record-printing release mechanism, indicating operation thereof;
Figure 10 shows diagrammatically and in detail a section transverse to that of Fig. 9;
Figures ll, 12 and 13 are similar views taken longitudinally through one point of the release mechanism illustrating modifications necessary to this mechanism to permit the castling move in chess, and these views show in three stages how the modified portion of the mechanism operates;
Figure 14 is a diagrammatic detail elevation view taken transversely to Figs. 11, 12 and 13.
It may be emphasized that the apparatus herein shown and described has been devised to record only the game of chess, with its plurality of pieces having different values and limits of movement, and with its involved rules and complications thereto such as in the case of the castling'move. After an examination of the operation of the recorder when used for this elaborate game, it will immediately be apparent how the principles of the invention are embodied for simpler games such as checkers and others. v
The principle of the recording mechanism is that each position in the playing area is accorded a separate column on specially-ruled recording paper, this paper being provided in quantity, say in rolls, for the printing machine. As each move is made, the printing mechanism will print, in a horizontal line across the page, a mark for each square, these marks indicating whether a chessman is located in the square and, if so, the nature of the piece.
Obviously, then, the positions of all pieces in the game will be recorded in one printing operation, such operation occurring automatically, as will be apparent below, after each movement by either player. In a game of chess, there are twelve different pieces (since each player has a king, queen, bishop, knight, rook and pawns) which must be represented by different printing marks, a thirteenth symbol being provided to indicate when any square is unoccupied.
Referring now to the drawings, wherein the same reference characters indicate corresponding parts throughout, Figure 1 shows that the unit may be conveniently enclosed in a sort of desk or table having a rectangular top portion 2i of sufiicient depth to contain the apparatus moving parts and supported chests or the like 22 at each end between which the knees of players seated on each side of the dest may be accommodated. At one end of the desk a clockcabinet 23 may rise above the top surface thereof to hold the time-interval recording mechanism,
the printing mechanism and the record paper. 9
On the side facing the players, cabinet 23 may have displayed-clock dials 24 and movementtabulating indicators 25 corresponding to each player.
The playing area 26 is seen in Fig. 1 to be a conventional chequered design marked on the desk top, which latter has an aperture 2'! therethrough in each position square. The game pieces or chessmen used with the recorder will have bases adapted to enter into said aperture when moved into any position so as to actuate mechanisms below the top cover of desk 20. Chessmen of different identities (there are twelve different identities, as noted above) will have diiferently shaped bases in order to actuate the mechanisms below the playing surface to a diff erent degree.
Figures 2, 3, 7 and 8 best illustrate the construction of preferred mechanisms underneath the playing surface to be actuated by the chessmen. The most important of these is the mechanism for transmitting information concerning the identity of a chessman in any position to the printing bar corresponding to that position. These identity transmitters constitute a plurality of levers 28 (one for each square) which are pivoted on rods 29 transverse the apparatus casing. One end of each lever is disposed directly under the aperture 27 of its square, preferably being formed in a horizontal ring 30, whilst the other end is coupled to the lower end of a type bar 3 I. v
The base of each chessman 32 (Fig. 8) is preferably shaped with a downwardly-projecting sleeve 33 of reduced dimensions and capable of entering aperture 21, whilst an axial bore will extend inward and upward from the outer end of the sleeve 33 for a distance corresponding to the identity of the chessman. The sleeve is adapted to rest over a washer 34 which, in its uppermost position (Fig. 7) closes the aperture 21 to enhance the appearance of the board when the chessmen are removed. There being twelve diffrent identities, accordingly the several pieces will have interior bores of twelve different lengths 4 from bottom to top, the length of sleeve 33 being the same for all pieces.
Underneath the playing surface, a pair of horizontal partitions 35 may be supported between surface 25 and the bottom 3? of desk casing 2|. Through each of these partitions, apertures 38 are provided which are directly below a corresponding aperture 21. An upright rod 39 is slidable in these apertures and carries a washer 40 secured thereon at a point between partitions 35. A spring M above upper partition 36 is coiled around the rod and under member 33 to urge it upwards. When the rod is pushed up until its flange 43 abuts the upper partition 33, the upper extremity of the rod should extend to the playing surface '26 whilst the lower end may approximate the bottom of lower partition 35. The ringed end 30 of each lever 28 will encircle loosely its corresponding rod below flange G0, and, as the rod is pushed down by the insertion of a chessmaninto any square, this end of lever 28 will be depressed accordingly and to an extent inversely proportional to the length of the axial bore 35 of the chessman.
Since a chess playing surface is eight rows square, naturally there will be sixty-four levers 28 and type bars 3|, and eight transverse rods 23 upon which the levers are pivoted. The positionsof the rods and lengths of the lever arms will be such that achessman will cause the same depression of a lever and lifting of a type bar regardless of where in the playing area it is positioned. The type bars will have on their printing surfaces 45 thirteen symbols spaced vertically, the correct symbol being positioned with respect to the printing mechanism according to the elevation of the bar, the latter being in its lowest limiting position when no chessman is in the square.
The type bars having been positioned, the printing mechanism may be of any desired conventional type although a preferred arrangement is shown best in Figs. 4 and 5. Here the record paper is supplied in a roll carried on transverse feed roller 5! and feeding up through the printing station 52 to an upper transverse drawing roller 53. The inking tape 53 may extend between a pair of rollers 55 one at each end of the record paper and journalled on upright axes. To force the paper and tape against the type bars in a horizontal line at the printing station, a pair of bars 56 may be piv'otally suspended from each end of an axle 5'! transverse the top of the cabinet, these bars being rigidly connected by transverse rod 58 and printing bar 59, the latter extending transverse the apparatus behind paper and tape and at the level of station 52. If the bars 56 and hence bar 59 be swung smartly to the right (Fig. 5) this will cause the paper and tape to be pressed against the type bars at the level of station 52 for printing purposes. As the bars 55 and 59 retreat, a pawl 60 pivoted on one of the former (56) will co-operate with ratchet wheel 8| at one end of upper roller 53 in order to displace the latter angularly. Roller 53 may be coupled to roller 5! by means of pulleys 62 and belt 53 and, accordingly, after each movement of a piece has completed a printing operation, the paper will have been displaced further onto the upper roller in order to present a new, clean, horizontal line to printing station 52.
In order to operate the printing mechanism in the manner described, obviously any method might be used or the cycle of operation might be carried out manually after each movement by a spending square. '69, a transverse pivot H is arranged in a pair of player. It is proposed, however, that; the mechanism functions automatically upon movement of a chessman, and that this same automatic motion actuates the time-interval recording mechamsm.
To this end, a second set of levers is pivoted below the top coverof desk 2| in the manner shown in Figs. 2 and 3. The free ends 65 of these levers 6B are formed in rings encircling rods 39 above springs 4| and below the top cover of the desk. The levers extend to the right and are pivoted on eight spaced rods 6! extending transverse the apparatus casing. When a chessman is inserted in position in a square, the sleeve thereof will force end 65 of the corresponding lever 66 downward, spring 4| urging the lever up upon removal of the piece.
In a transverse line across the casing and pivotally suspended from the levers 66 intermediate their ends is a row of pawls B8. The spacing of rods 61 is such that no matter in which playing position a piece is inserted, it will cause the lever pawls to be depressed an identical distance. And the lower ends of all the pawls are maintained by their own weight in engagement with a ratchetshaped cylinder 59 journalled on a shaft transverse the casing and below the levers.
Figs. 9 and 10 show that when a pawl is depressed, it causes ratchet cylinder 69 to rotate a distance equivalent to the pitch of one tooth. The pawls corresponding to levers 66 in raised position are permitted by their pivotal suspension to slip one tooth and hence remain in readi' ness for when a chessman is inserted in the corre Near one end of the cylindel supports 12 extending up from the bottom 31 of the casing. Another pawl member 13 is journalled on this pivot and is held in contact with the bottom of the cylinder by a rightwardly-extending (Fig. 9) weighted arm 14. The engagement of pawl 13 with the cylinder helps to keep the latter constantly under control and prevents any rotation in a sense reverse to that described. However, when positively driven around by depression of one of the levers 66, the cylinder depresses pawl '13 against the counterbalancing of member 14 and tilts to the left (Fig. 9) an arm 15 extending vertically upward from the pawl 13 at its pivotal point.
Figures 2, 3 and 10 show the effect of this tilting-of arm 15. On its upper end, this latter carries an offset pin 16 engaging and holding against rotation a circular member 11 carrying segmental abutments on portions of its circumferences. 1
That is, the member I1 carries a raised segmental abutment 18 on over one-half of its width for less than a quarter of its circumference, there is a space across the circumference and then another abutment 18 on the other side thereof, another space, and so on; there being four spaced abutments in all alternating as to the side on '18 (by depression of lever 66, rotation of cylin der 69 and depression of pawl 13) member I1 rotates through a quarter of a circle, allows pin 16 to return to its original position (upon comple- 'tion of the movement of cylinder 69 and subseduent elevation of pawl 13 under weight of member 14) and rotates through another quarter of a 6 circle until pin 16 again abuts against one of the raised portions 18.
The semi-circular displacement permitted shaft 80 causes operation of the printing mechanism and time-interval controlling mechanism. In the former case (see Figs. 4 and 5) the shaft extends leftward and has keyed thereto in co-operation with the lower end of one bar 56 a cam member 82. This cam member is circular in outline with a flanged circumference 83, the flange shaped with two slopes thereon, end to end and each occupying half of the circumference. A roller 84 may be provided on the lower end of bar 56 which will normally be held, as by spring 85, with the roller slightly away from one of the depressed portions of the cam surface when the latter is at rest. Upon rotation of the cam, however, the sloped portion thereof forces the lower end of 56, and hence transverse bar 59, to the right, thus causes the printing operation to take place. Upon completion of a semi-circular displacement, the roller reaches the recessed portion of the cam and so is permitted to move leftward, carrying its associated parts therewith.
Figure 6 shows the elements of the time-interval recording mechanism, including a pair of timing clocks 99 and a pair of movement indicators SI for the players. A bar 92 extends transverse the apparatus below the clocks and is pivoted centrally (on a fixed pivot 92A), having also a downwardly extending arm 93. The lower end of arm 93 is coupled to one end of a transverselyslidable rod 94, the other end of which abuts against the surface of a cam 95 keyed to shaft 80. A spring 91 presses against arm 93 so that contact between cam and rod end is maintained, and the cam is designed to cause a rocking of arm 93 past the vertical from one side to the other with each semi-circular angular displacement. Accordingly one end or the other of bar 92 will be in an upper position, depending on the disposition of the cam.
On each end portion of bar 92, an upwardly extending rod 98 will act as a stop arm locking and releasing the escapement to the corresponding clock at the right moment whilst a pawl 99, pivoted on the extremity of 92 and held in engagement with the ratcheted exterior of the movement indicator by a counterbalancing arm 99A will control the movement of the indicator.
The mechanism will be adjusted so that, as a player moves a piece and releases shaft 80, cam 95 will cause the end of bar 92 corresponding to this player to move up. The pawl 99 thus being actuated causes the indicator 9i to move angularly one division, showing the player to have made one more move. The rod 98 moves up and stops the clock. At the same time, through the depression of that end of bar 92 corresponding to the other player, the latters clock commences to record time and his pawl 99 retreats in readiness for another upward movement.
It is proposed that from each clock a rod I00 extends centrally rearward to the printing station, this rod rotating in unison with, say, the minute hand of the clock, and adapted to mark on the record paper an arrow indicating the position of this hand.
It will be remembered that in chess there is a movement known as castling, in which both the king and a, rook are moved at once. Figures 11 to 14 inclusive show modifications which are applicable to the apparatus and which prevent such a complicated move from interfering with the recording operation of the machine. In this case, it is essential that the kingbe moved first, the idea being to prevent recording by the machine until the rook also has been moved in the event that castling is to be employed.
Normally, when the king is moved, it can only travel one square at a time. During castling however, the king should jump right or left two squares. Thus the mechanism should be prevented from recording only when the king is moved in the latter manner. Looking at Figs.
.11 and 14, it is seen that the alternative squares to which the king might be moved during castling are characterized by the elongated lower ends 68A extending down from the pawls 68 of their respective levers 66; Underneath the lever 65 corresponding to each king's starting position, a lever IilI is freely pivoted to the bottom of the casing and extends up therefrom, having a transversely'projecting rod I02 engaged (at the start) under extensions 68A. The upper extremity I03 of lever IllI abuts, at the start, against a finger I04 depending from the kings lever 65, this finger thus preventing lever IOI from toppling to the right. a
When the king, is lifted from its starting position, however, finger I04 is elevated and no longer holds lever IOI. The latter falls towards the right and, by virtue of rod I02, lifts the pawls 68 having extremities 68A out of engagement with the cylinder. A bell crank I05 is pivoted at I06 below cylinder 69 and has one pawled extremity I01 in engagement with the latter and another toothed extremity I08 engaging a toothed hub I09 on the base of lever WI. The normal position of the bell crank, when the cylinder is stationary, is such that tooth I08 will allow lever I02 to fall only a limited distance to the right upon being released by finger I04. This limiting position is shown in Fig. 12 and indicates that the lever has fallen just far enough to lift the elongated pawls 68 as described above.
If the king is now placed in either castling position, no recording will take place since the pawls 68 corresponding to these positions are not in engagement with the cylinder 69. On the other hand, if the king makes any other legal move, it will cause rotation of cylinder 69, upon being set down, and this will displace bell crank I05, lift tooth I08 out of engagement, allow (Fig. 13) lever IOI to topple to the right, and return pawls 6868A to engagement with the cylinder. The castling mechanism will then be inoperative, but castling is illegal after the king has once been moved.
On the other hand, if castling is carried out, the subsequent movement of the rock will also cause the machine to operate in the manner noted immediately above, the movement being recorded and the castling mechanism being rendered subsequently inoperative until reset manually at the beginning of a new game.
It is proposed that shaft 80 be continually urged to rotate by some means. A suitable arrangement is shown in Figs. 2 and 3, wherein a drum H is disposed transverse one end of the apparatus and carries a weight III on the end of a cord II2 wound therearound. The weight will urge rotation of the drum which may be imparted to the shaft through a suitable chain of gears H3 at one end of the drum, said gears held in clutched position by spring I I4. A handle H at the other end permits rewinding of the cord on the drum, inward pressure on the handle serving to declutch the drum.
Obviously, from the foregoing, the present invention fulfills the objectives hereinbefore. set forth. A practical apparatus, capable of embodiment in a convenient attractive unit, has been disclosed for the recording of all the movements in such games as chess, checkers, etc. The operation of the apparatus is foolproof. and it is capable of recording even in the face of the complicated rules employed in such a game as chess.
It may be emphasized'that the fundamental parts of the apparatus are the following:
A game board including a divided playing area;
Game pieces having bases characteristic of their identity;
Levers corresponding to all the board divisions which are acted upon by the pieces to set up in a printing mechanism symbols, one for each division, which indicate what piece if any is located at each division.
Means for operating the printing mechanism after each move, manually or automatically.-
These fundamental mechanisms may be elaborated, as in the present instance, to record auto matically and to provide for games having more complicated rules.
It will therefore be understood that I do not limit myself to the particular embodiment of my invention herein shown and described, since obviously various alterations might be made in the size, shape and arrangement of parts without departing from the spirit of the invention or the scope of the subjoined claims.
