1i claims. (o1. 213-136) This invention relates to chessboard boxes, and has for one of its objects the production of a simple and efficient means for facilitating the handling of chessmen in a manner to provide convenience, order, efficiency, durability, intelligence, cleverness and pleasure to the players while playing the game of chess.-
A further object of this invention is the production of a simple and efcient rack for receiv` 1oing chessmen which are removed from the playing board while playing chess, which rack is so constructed as to locate all of the playing pieces of each side in the same relative positions as when placed on the board at the beginning of l5: the game.
Another object of this invention is the production of a simple and ecient means for attaching the racks to the playing board and folding the board around the racks in a manner whereby the racks, board and chessmen are fastened together into a neat and substantial box.
Other objects andv advantages of the present invention will appear throughout the following specification and claims.

Be referring to the drawings it will ybeseen that 3d y' A designatesthe chess-board box in general, which comprises a playing board 30 which is hinged longitudinally, asat 3|, tou provide foldalolesec-v tions which -encase the box sections or racks 32, which box sections or racks provide framing del s vices, These box sections 32 or racks are detach'-v ably secured to the corners of the playing board v30hy means of spring snap fasteners 33 ofthe conventional type, as shown in Figure 1, and the box, sections or racks 32 are detachably held in nestedl relation by means of spring snap fasteners 34 similar to the fasteners 33, thereby holding the chessboard box in rm assembled position, A plurality of these snap fasteners 34 may be providedv upon vthe adjoining faces of the box sec-tions .or u racks 32. rThese spring snap fasteners 33 and 34 may be of the conventional type, such as isillusf trated in detail in Figure 8. Each rack or box section 32 is provided with a plurality of rows of chessmen-receiving apertures 35 and 36 which 50 'extend vertically through the box in the manner as shown in Figures 3, 4 and 5. The apertures 35 at one end are preferably beveled, as at 31, to facilitate thedropping of the chessmen 38` lin position, as will be hereinafter described, and the 55 opposite ends of the apertures 36 are notched, as at 39, to facilitate the moving of playing pieces to place them in proper positions upon the board. Attention is particularly directed to Figures 14 to 21 of the drawings, and especially to Figures 19 and 20. 'I'he notches 39 will permit the blocks to be shifted laterally to separate the pawns from the pieces about one-half inch over their previous positions had prior to this movement and this is l0 the manner in which the pieces or men finally find their position each over the center of its respective square. This structure will allow the parts to be reduced in size so that the chessboard may reach around the blocks when folded.
Each rack or box s'ection 32 is provided with track channels 4U upon its longitudinal side edges in which track channels 46 are slidably mounted the inturned flanges 4| of the plates 42. These plates 42 are slidable longitudinally of the racks 20 or box sections 32. The racks or box sections 32 are 'preferably made of balsa wood to provide a light structure, and the plates 42 are preferably formed of light sheet metal. The plates 42 are provided with apertures 43 which are adapted to register with the respective apertures 35 and 36 formed in the racks 32 to permit the chessmen to drop through the apertures 43 in the plates into the apertures 35 and 36.
When the game is not in use, the chessboard 3Q box is arranged in its assembled position, as shown in Figure 1, 2 and 5, thereby providing a very compact and assembled box within which the chessmen kare contained and are ready for instant use. When it is desired to use the game,
361 the box is placed in the position shown in Figure 14, this being an end View of the box. 'Ihe boX is pickedup by using both hands with the thumbs ontop and the fingers underneath the box and in such a fashion that the box is pointing away from 40 the'body of the operator. By rotating the hands outwardly so that the thumbs separae or more away yfrom each other, the box will be brought to the position shown in Figure 15, and it is important thatthe two center sections of the chessboardzor4 playing board stand up in the form of an invertedjv, as shown at the center of Figure`15. 'Ihe purpose of this position is to keep the chessmen from falling out of the apertures 35 and 36 which constitute receptacles for the chessmen.
k5() By continuing to rotate the sections of the box outwardly, the position illustrated in Figure 16 will be reached. If the box sections'32 are now separated still further, the board will be stretched out flat to the position shown in Figure 17. The
L5 5 box sections 32 are then unsnapped from the board by pressing the ngerdown against the center of the chessboard and near the edges of the box sections at the points b-b, after which a slightly further rotation of the box sections out- 60 wardly away from each other'will result in their being released from the snap fasteners. The box sections are then permittedto fall back on the board with their contents of chessmen located in the apertures 35 and 36 and the box sections are .6,5 then slid an inch or so toward the center ofthe board to the position shown` in Figure 19. The box sections or racks are then slid back toward the edges of the chessboard until the movement is stopped by contacting the snaps 33 mounted in l70 recesses in the bottom of the racks. This movement is indicated in Figure 20, and results in each man being centered on its proper square on the playing'board, the playing board being of the conventionalchessboard type. The formation of the #1,5 bottom of the-apertures 35 and 36 as previously described, will facilitate the lifting of the racks vertically from the board, thus leaving all of the men on the board in their proper respective positions. The racks or box sections may be lifted in the direction as indicated by the arrow in Fig- 5 ure 21, and as also further indicated in Figure 13.
When the racks 32 are lifted as above described, they are then placed on the table preferably at the left-hand edge of the board and parallel thereto as illustrated in Figure 5a. One rack 10 may be colored black, and the other white, for containing the respectively colored chessmen. The racks are so placed that the white rack is next to the board and the black rack is spaced further away from it. Also the racks are placed 15 so that the holes for the pawns are next to each other, as indicated in Figure 5a. The slide plates 42 are then displaced so that the apertures 43 will be offset with respect to the apertures 35 and 36, and preferably located between the apertures 20 formed in the racks, the apertures 43 providing a rest for receiving the pawns and supporting the pawns in proper position to allow the players to tell at a glance the relative strengths of the two sides on the chessboard. It is obvious that by 25 again sliding the plates 42 to bring the apertures 43 into registration with the apertures 35 and 36, the chessmen or pawns may drop into the apertures 35 and 36. Each rack is provided with a series of apertures 35 and a parallel series of 30 apertures 36, as above described.
As the chessmen are taken from the board in the course of the game, they are placed each in its respective hole in the cover or slide plate 42 and rest upon the solid part of the rack be- 35 tween the apertures formed within the rack. When the game is finished, any men remaining are transferred to the rack. The racks and their contents are then placed on the chessboard and snapped thereto. The plates 42 are then moved 40 to the position to bring the apertures 43 into registration with the aperturesI 35 and 36 causing the men to drop into the receptacles or apertures 35 and 36 and rest upon the playing board. When the chessmen have fallen through the aper- 45 tures 35 and 36 they will rest near the center of the squares on the chessboard and in the proper relative positions where the playing piecesI or men belong for the beginning of the game. The racks may be given a slight forward and back- 60 ward movement with the result that each piece is centered in its proper square. These racks may then be lifted as previously described for the purpose of playing another game. In playing the game, the racks are placed as shown in Figure 5a, so that the pawn receptacle holes are facing each other and the plates 42 are moved in a position so that the chessmen may besrupported on the top of the racks as previously stated. When the players are ready to discontinue the playing, the racks are placed on their proper edges of the chessboard and snapped fast in position through the medium of the fasteners 33 and a slight movement of the plates 42 will cause the chessmen supported upon the rack to drop into their respective apertures 35 and 36. The chessboard is then rolled up around the racks or box sections following the reverse steps illustrated in Figures 21 to 14, this being possible due to the Ahinge formationsI 3l of the chessboard 70 being so placed that they t just at the corners of the racks or box sections 32. When the two uncovered faces of the box sections or racks come against each other a slight pressure from the outside causes the snaps 34 to fasten together into 75' aneat and substantial box. When the game is in progress, a piece is taken from the board and is placed upon the rack in sucha position that at the end of the game all of the pieces of each side are in the same relative positions as when placed on the board at the beginning of the game. By this procedure, each White piece is placed opposite to the corresponding black piece, thus enabling the player at a glance to Ycompare the relative strength of the men left on the eld which is essential in determining the strategy to pursue.
From the foregoing description, it will be seen that an important feature of the present invention is the compactness of the structure' which has been provided whereby the racks 32 are folded up Within the chess game board 3 of the conventional type, the game board being hinged, as at Si, so as to allow the game board to be wrapped around the racks 32 and to be fastened thereby by means of the snap fasteners 33. The racks 32 are provided upon their adjacent faces with a series of the fasteners 363 which will firmly hold the racks 32 in assembled relation when the adjoining faces are brought to abutting relation such as is shown in Figure 2, in tris way avoiding the necessity of providing an additional case or providing a tying band or other securing means independent of the board and racks. 4
Furthermore, it should be noted that the beveled ends of the apertures 35 will facilitate the dropping of the chessinen 33 therethrough when the apertures i3 of the platesy d2 vare brought into registration with the apertures 35. Furthermore, the formation of the apertures 35, as
' at 39, will facilitate the lateral shifting ofthe racks to properly place the chessmen in their positions.
By referring to Figure 1l, it will be noted that the chessmen may be placed upon the top of the racks when the apertures i3 are brought out of registration with the apertures 35 and 36 when the plates 'e2 are moved to such a position. By moving the plates 42 in the direction of the arrows as shown in Figure 11, it will be noted that the apertures t3 will be brought into registration with the apertures 35 and 35.
As shown in Figure 6, certain of the apertures 35 may be marked for the king and queen, and if it is desired, certain other markings may be provided and certain other detail changes may be Asubstituted without departing from the spirit of the invention, so long as such changes fall within the scope of the appended claims.
In Figures 22 to 24 inclusive, I have shown a modified form ofthe invention wherein a playing board $5 is illustrated consisting of a oentral section IE6 and two side sections hinged thereto and numbered @l and 58 respectively. A hollow box-like form 53 is detachably secured to each end of the playing board 45 by means of suitable snap fasteners 5B similar to the snap fasteners previously described and indicated by the numeral 33. Inside form 53 isl a rack or framing device @9 that can be made to slide therein in the direction of the arrows shown. This rack 4S is provided with apertures 5l and 52 shown by dotted circles for receiving the chessrnen for spacing them on the board or for storage when the game isI finished. The form 53 is also provided with apertures on its upper face as shown by the solid lines 54. By sliding the rack 49 towards the center of the board, the chessmen may be caused to drop into the apertures' 5l and 52 in a manner similar to that previously described. Hinged gates' 55 are secured at each end of the form '53 to provide fillers forl closing the ends of the spaces between the sides of the forms 53 and the section of the board 46, asI shown in Figure 24. Gates 55 are opened by sliding the rack 49 towards the center of the board and are closed by spring hinges In Figures 25 to 28 inclusive, I have shown a further modified for-m of the invention which is so constructed as to econornize as to space, and in this form I have illustrated a playing board 60 and a special type of rack 6l having apertures 62 formed therein for receiving the pawns 63, the apertures 32 being spaced sufciently to provide a bridge 63a between the apertures 62 to support the pawns when desired. A tray 64 is hingedly supported lupon the pivoted links 65, which links are connected by a transverse journal rod 66 to the tray 64. These links 65 are in turn connected to the sides of the racks 6 i, as shown in Figures 25 to 28, inclusive. This tray 6i! is pro vided with a `plurality of apertures 6l at the bottom thereof registering with lthe apertures 68 at the top and between which is slidably mounted a sliding plate EQ having suitable apertures l0 adapted to be brought into registration with the apertures S5 and 6l to allow the pawns to drop therethrough and be positioned in the proper places upon the board t@ in a manner similar to that previously described. The tray 64 may be supported in the position shown in Figure 2'7, and when the pawns are .to be placed upon the board, the tray M may be placed in the position shown in dotted lines in Figure 27. For the purpose of compact assembly, the tray 54 may be swung into the channel ll upon the inner `face or" the rack 6i in a `position as shown in Figure 28, the pawn or chessmen l2 ntting in the socket 13. The chessboard 62 may then be folded around the racks fil in the manner shown in Figure 25. A cover plate ll2a simi-lar to the plate i2 is provided in the struc-ture shown in Figures 27 and 28. The shaft 5t is essential for the reason that the links at the opposite ends of the blocks are kept parallel to each other, thus holding the pawn tray in a proper position through the medium of the links 65. Thejoint between the links 65 and the tray 6l is of a friction and stop type to Ifacilitate the holding of the tray in three selected positions. When the joint is opened to its widest angle i-t is stopped in the position for the tray in its elevated position. When it is pushed down against the chessboard the board itself will furnish the stop vto determine its position. When the pawns are pushed into closed Iposition in the storage rack Si the rack itself will furnish the stop. In all positions the friction in the two joints will support the weight involved.
Fromthe foregoing description, it will be seen that a very entertaining and convenient game apparatus has been provided, whereby the game apparatus is compactly assembled for convenient use and whereby the playing pieces may be kept in proper order.
