Application January 29, 1947, Serial No. 725,043 10 Claims. (Cl. 273-430) The present invention relates broadly to a rotatable block apparatus, and in its specific phases to a game apparatus.

Games played with building blocks have proven to be exceptionally entertaining and instructive to small children, but of little interest to adults. n the .other hand, games of high skill have been fascinating to adults, but of no interest to children, due to the difficulty and mental concentration' involved. Perhaps the reason why these particular games have been so interesting to the respectivegroups is that there is a natural desire to accomplish some end, and that, in turn, is enhanced when there are physical elements to moveplus the requirement of skill in doing so.- 'Another game which has proved tobe fascinating to both adults and children, and which has physical elements, is the one which is variously known as' naughts and crosses, or tick-tack-toe, or criss-cross. This game is played with a pencil and paper wherein double cross lines are drawn on the paper and then the players, by alternate plays, try respectively to get three naughts or three crosses in a line, a thing which wins the game. This procedure is commonly carried on until the paper or pencil is used up, although it is sometimes detrirnentally played on wall surfaces, table.

cloths, or the like. It was a recognition of these amusementfeatures of the two types of games which led to the conception and development of the idea of combining same and playing the game of fcriss-cross with a mechanical apparatus having fixed location rotatable blocks, each of which exhibits a naught, a cross, and a blank.

- Accordingly, among the objects of the present invention is the provision of" a simple and interesting mechanical apparatus, the parts of whichare anchored in place to prevent loss, and adapted for use in playing the game of crisscrossiw ithout theuse of ,a pencil and paper, or

other equipment.

, -Anotherobject is to provide an apparatus with rotatable blocks wherein a tap on the edge of one face of a block will rotate same to bring another face up.

Another object is to provide means for causing the blocks, when rotated, to stop with their upper face substantially horizontal.

l Another object is to provide a rotatable block "criss-cross game which has a scoring means. A further object is to provide a game structure which is simple, compact, and economical to manufacture,

axle for each cross row of blocks, or individual mountings for each block.

7 A further object is to provide, modified construction triangular blocks with parallel ends,

said ends having triangular trunnions with the points of same facing the sides of the block, the

frame for receiving these blocks having substan-' tially fiat bottom vertical slots so that said trunnions may rest on same with the upper face of the blocks substantially parallel with the top face of the frame, said blocks being rotatable so that any one of the sides may become the top face.

7 A still further object is to construct the apparatus so as to facilitate clearing same ready to start a new game.

Still further objects and advantages will appear as the description proceeds. To the accomplishment of the foregoing and related ends, the invention, then, consists of the;

means hereinafter fully described and particularly pointed out in the claims, the annexed drawings and'the following description setting the invention, such disclosed means illustrating, however, but several of various ways in which the principle of-the invention may be used.

Figure 9 shows a perspective view of a block with trunnions adapted for use with the frame and cover members illustrated in Figures '7 and 8.

Referring more particularly to the drawing,

Figure 1 shows a preferred form of the invention which utilizes a frame I having partitions 2 and a set of nine pivotally mounted blocks 3. A scoring device may be provided at each end of the assembly, and one convenient form of this includes a rod 4 mounted on extending ears which are a continuation of the sides of frame I. Strung on this rod 4 are a plurality of bead-like members 6, which only partially fill out the space between ears 5. In order that two players may individually score the number of games which they have won, one of these scoring devices may be mounted on each end of the assembly, as is shown in Figure 2.

Frame I with its sides, ends, and partitions may be stamped from a single piece of sheet metal, or it may be made as a composite assembly from either metal, wood, metal and wood, plastic, or the like. Where the frame assembly is made from one piece of sheet metal, as is more particularly illustratedin Figures 1 and 2, the joints are preferably fastened together, for instance by spot welding or soldering. Openings in the frame for the blocks 3 are preferably made by diagonally cross slitting the opening area from corner to corner, following which the four triangular tongues I are bent down as shown more particularly in Figure 2, the end tongues being bent slightly beyond perpendicular to the top face of the frame to provide ample clearance for blocks 3 during the rotation. The side tongues l, on the other hand, are preferably bent to perpendicular position andperforated for three rods 8, 9, and II], on which blocks 3 are pivotallymounted for a purpose to be hereinafter described in detail; In order to space the ends of each of the blocks 3 from the adjacent tongues l, spacing washers ZlZ'mayv be used. These washers are preferably of a thickness substantially taking up the space between blocks 3 and tongues 1 while allowing the blocks to freely rotate.

. A blank II, as shown in Figure 4, is used to form'an individual block. This blank has a plain center panellZ, onone edge ofwhich is a' zero panel I3; while on the opposite edge is attached an X panel [4. Attached to the other pair of edges of the center panel are a pair of isosceles triangle shaped end panels l5 and N5, the side edges of which are of the same length as the side edges of the zero and X panels. The outlines of thecenter'panel are shown by dashed lines which are the bending lines about which the four attached panels are bent downward to form the assembly shown in Figure 5. For inexpensive constructions, the adjacent edges of the panels, after bending to form the block, would be left unattached, although in the more expensive toys, those edges would be welded, soldered, orotherwise fastened together. The X and the zero on the inexpensive construction blocks would be painted thereon, while in the more expensive toys, they would be embossed and then painted. The use of embossing, is shown in Figures 1 and 5, while the plain painting is illustrated in Figure 3.

End panels I 5 and I6 are provided with isosceles triangle perforations, H, the apexes of which are respectively directed at the corresponding faces of the finished block; as shownclearly in' Figure 5.

These triangular perforations, which form the hub of the block, are made of a size sufficient to facilitate mounting on rods 8, 9 and H), as shown in Figure 2, so that when the block 3 is rotated, the triangular perforation will shift from apex to apex thereof on the rod, and, since each apex is above the center of gravity of the block, the latter will come to rest each time with its uppermost face substantially horizontal.

The assembly shown in Figure 3 has wooden partitions 2a. which become part of the frame la to which is fastened an outer continuous sheet metal strip 18 by means of screws or tacks l9. The sheet metal strip [8 will protect the blocks 3 from accidental injury under normal conditions of use, and, at the same time, makes possible a very simple construction of both wood and metal.

The use of rods 8, 9, and Hi, as shown in Figure 2, may be avoided by following the construction shown in Figure 6. Here the pivot portion of each of the side tongues la is perforated on three sides of a prechosen location rectangular area and half way down the fourth side, following which, each is folded and bent as shown to form the pivot 20 on which blocks 3 can rotate. The slope of this tongue is preferably the same as the slope of triangular openings l7 when assembled, but is not limited to same since other slope angles may be satisfactorilyused to permit the top face of the blocks to come to rest in substantially horizontal position. It should be noted in this connection that in Figure 6 on the right-hand tongue la, there has been indicated by dashed lines where integral pivot 20 is-to be bent and by solid lines where it is to be sheared, while the left-hand tongue la shows this integral pivot 26 sheared and bent to finished position. While the top and bottom tongues have been bent down into place, the edges of pivot carrying tongues 1a are shown with dashed lines 2|, thus indicating where these tongues are to be bent to form the downward depending tongue construction generally illustrated in Figure 2. All of these tongues are part of the sheet of metal which is used to form frame lb with its sloping sides as illustrated in Figure 6.

For convenience of forming the particular assembly shown in Figures 1 and 2, the blocks 3 may be mounted on rods 8, 9, and I0, before one or both of the side panels which carry ears 5 are bent down to the final assembled position shown, and in which position, they may be fastened, for instance, by interlocking, welding, brazing, or soldering. Rods 4 with bead-like members 6 would also be installed'in place before the sides are bent and anchored in final position. In the cheaper constructions, the interlocking, welding, brazing, or soldering of the side members to the members 23 may be omitted, and if desired, the outer ends of rods 4 may be bent down to hold the sides in assembled position. This construction, however, is not very rigid, and it is preferable to positively anchor the side members having tongues 5, to end members 23. A still better construction involves the use of a bottom panel 24, Figure 2, with up-turned edges 25, which may be soldered or otherwise fastened to the side and end members of frame I. The smooth bottom thus provided maybe safely laid on the finest furniture without danger of scratching same, and if desired, a piece of felt or the like may be glued to the bottom face of panel 24 so as to minimize slippage when used on tables; or the like.

While the present invention readily lendsitself 5.. to production from-isheet'metal, or sheet metal and wood, it is also adapted to molding from plastic material as well as die casting from metal.

Frame is shown in Figure 7 is particularly adapted for construction by the latter procedures. For

improved appearance the edges of frame lo are' preferably flared out slightly at the bottom, and a top grill 26, Figure 8, provided for the assembly. Thecorners of this grill may be provided with openings 21 which are preferably countersunk for flat head screws 32 which are adapted, infinal assembly, to engage threaded openings 28 in the top face of the frame lc.

I-Frame I is provided with partitions 2c, and

two of these partitions are provided with fiat bottomed parallel bearing slots 3| while the corresponding side walls have parallel slots 3 la. The slotted partitions may be used alone withoutly from the walls or partitions carrying the sup-' porting'slots. These blocks may beprovided with markings as described in connection with block 3, or other insignia maybe used as desired for playing other games, such as picture puzzles, and theshowing is intended to diagrammatically illustrate these variations; Blocks Scmay be cast of plastic with the trunnions in placaor same maybe made of wood, metal, or other suitablev material and the trunnions added later. Where the blocks 30 are tobe used for playing the game of criss-cross, the trunnions are preferably offset slightly toward the blank face for a purpose to be hereinafter described.

' I With a triangular block 30 the trunnions will preferably be in the form of isosceles triangles withthe points of the triangle pointing toward the adjacent faces of the block. When the blocks are placed in the frame with the latter in horizontalposition and the trunnions in the slots, one of the faces of the trunnion will rest on the bottom face of the corresponding slot which in turnwill permit the upper face of the block to assumefa plane parallel with the top face of the frame. When all of the blocks are in place in frame Ic, grill 26 is mounted thereon and anchored in place in conventional manner. This grill, .in turn, holds blocks 30 in fixed location while permitting same to rotate.

While the game has been illustrated with nine rotatable blocks particularly adapted for playing the game of criss-cross, it is to be understood that the apparatus is not limited to nine blocks, but that more or less blocks 'may be used, and the showing is to be considered as diagrammatically illustrating variations of thisfnature. n is furtherqto be noted that while triangular blocks with triangular perforations ll have been used-to explain the principle of constructing the rotatable, blocks 3,, the latter are not limited to specific triangular shape, since, for instance, a square block will operate in like manner, wherein the perforations for the axle rod are square and thepoints of the'pcrforation directed toward the respective faces of the block. With this in mind, it isto be considered that the blocks 3 illustrated in placein 2 Figures l and'3, diagrams ditionfor playing once more.

ofblocks usable in accordance withthepresent invention. 7

To play the game, the blocks are all turned so;

that the center or blank panels l2 are-up. In

this case, the under face of all the. triangular blocks at one end of the assembly will be zeroj' while all of the faces of the blocks at the other The player at the endof the game assembly having the zero" on the under face, may make the first playby deciding;

side, carry an X.

which block he wishes to play, and then, by tapping the adjacent edge of that block, it will rotate so that the next face will turn up and that face will carry an X. This block, for

the adjacent face is up and that face will; carry a zero. Such block, for instance, may. be the one shown at the lower left -hand edge,of .the.

assembly illustrated in Figure 1. The playing then continuedin rotation until either a stalemate is reached, or one of the players gets three of his marks in line, and wins. The blocks] are then turned back to the blank faces and a new,

game is started inalike manner. i

In order to simplify the clearing of the game back to blanks to start over, it is preferable to shift the triangular opening ll, or trunnion-$29, just slightly toward the blank face of the blocks which, in turn, will move it slightly awayfrom' the other two faces. This will'shiftthe center of gravity and make it slightly lowerin connection with the blocks when theblankfaces are up.

With this type of construction, when it is desired to clear the game, the assembly is picked up and the whole given a quick rotation in the 'air so as to cause the blocks to rotate due to this off-center mounting. Under these conditions, when the blocks come to rest, the most of them will stop with blank faces up, another quick rotation of the assembly will substantially clear all of the blocks to blank face up, and this to-' gether with individual turning of any remaining X or zero blocks will place the game in con Other modes of applying the principle of my invention may be employed instead ofthose ex-- plained, change being made as regards the apparatus herein disclosed, provided the means stated by any-of the following claims: or the equivalent of such stated means be employed." 1 therefore particularly pointout and distinctly claim as my invention: 1
