3 and 4, will be the same in whatever posi tion the cover card is placed in proper registry with the board. Any of the cards shown in Figure 3 may be placed upon the board shown in Figure 2 in any position and either side up, and the sum of the numbers disclosed through the perforations will always he the same, namely 34 in the present case. This is clearly shown in Figures l, 5, 6 and 7 in which the card 17 is shown placed upon the board shown in Figure 2 in four out of a possible eight positions. lVhile only four positions are shown, all eight positions will give the same result.

Figures 9 and 10 show a slightly modified construction of the puzzle board 12. In this construction the puzzle board 32 consists of two sheets of card board or other suitable material mounted one upon the other, the upper sheet having perforations 33' adapted to receive the number plugs 14, and the lower sheet having somewhat smaller perforations 34 arranged to register with the pen forations 33 of the upper sheet so as to form a shoulder 35 adapted to support the plug 14:. The hole 3a allows for the insertion of the finger, to remove the plug.

The arrangement of numbers shown in Figure 2 is, of course, not the only arrangement that can be used for a puzzle according to this invention. Numerous other arrange ments are available. Such arrangements are in fact so numerous that it is convenient to havea key whereby a new number set may be obtained at any time. Such a key is shown in Figures 12 to 15 inclusive. This key comprises a board similar to the puzzle board which may be provided with a set of symbols in place of numbers arranged in a pattern similar to that of the puzzle board. In the present instance, the letters of the alphabet have been used as syinbols. This board may be sub-divided into a number of sections, in the present instance, four quarter sections 10 to 43 inclusive. The quarter sections may be provided with finger notches 4:4 for convenience in manipulation.

It willbe seen that the letters in Figure 12 taken in alphabetical order are arranged 1 in the same pattern as the numbers in Figure 2 taken in numerical order. In other words, by substituting, in Figure 2, A for 1, B for 2, C for 3, etc, in alphabetical and numerical order respectively, the arrange ment of Figure 12 is obtained. The arrangement of Figure 2 can .be obtained from the arrangement of Figure 12 by reversing this process. Similarly, by substituting in Figure 12 any other set of consecutive numbers, maintaining, of course, the correspondence of alphabetical and numerical order as pointed out above, a new number set will be obtained, which will fulfill the requirements of this invention as pointed out above. The numbers substituted need not, however, be in consecutive numerical order, but number sets may be obtained by a process to be described hereinaftr-ir, which when applied to the key shown in Figures 12 to 15 inclusive, or any of the other keys to be described hereinafter, will produce a number pattern which will fulfill the requirements of'this puzzle.

With any given number set applied to the key of Figure 12, a number of different number patterns may be obtained by manipulation of said key. If each of the quarter sections blocks 40, 41, 12 and 43 is rotated in dividually in the same direction through ninety degrees from its position in Figure 12, as indicated by the arrows in that figure, a second pattern will be obtained as shown in Figure 13. This pattern will also fulfill the requirements of the puzzle. This operation may be repeated and after rotation will produce a new pattern. The fourth pattern so found is shown in Figure 14.

If the above rotation be again performed on Figure 14, the original pattern of Figure 12 will be obtained. If, however, instead of repeating said rotation, the two lower blocks of Figure 14 be transposed so as to lie above the two upper blocks as indicated by the arrows in that figure, a new pattern will be ob tained as shown in Figure 15. (The two right hand blocks may be interchanged with the left hand blocks just as well.) Starting with the arrangement of Figure 15, the rotation process can again be performed three times, obtaining a new pattern each time. Thus from the key of Figure 12, a total of eight different patterns may be obtained.

If we start with other patterns than those shown in Figure 12 by using the same set of symbols, still other number patterns may be obtained from the same number set, which willfulfill the requirementsof the puzzle. A number of key patterns which may be used are shown in the following tabulation in which the letters given in the first line correspond to those of figure 12 and each succeeding line gives a new pattern which may be applied to the key by substituting each letter in that line for the letter above it in column in the first line.

From each of these, eight patterns maybe obtained by the rotation process described above. It will be seen that by this process a large number of different number patterns may be obtained from the same number set.

An enormous number of different number sets may be obtained which when applied to th key described above will fulfill the con ditions of the puzzle. A method of obtaining such number sets is illustrated in the following tabulation. In the first line are. the let.- ters or other symbols cerresponding t the key of Figure 12- Each succeeding line repres n a w num r set h h may be an:

Wherever the Same letter appears, said difference must be th same. These differences may have any value,

but such value must always be the same for the same letter during aSer-ies. Thus,

fourth series of numbers given above, one of the numbers is zero. This, of course, is

the same as if 110 number at all were given,

or a blank space left on the board.- This means that when the puzzle is presented for solution the .zero may be replaced by some arbitrary number which will prevent asuc cessful solution. until'discarde'd. In suchacase, of course, instructionsshould begiven to discard, or replace one number. It [will be obvious also that any other number than zero can be treated in the same way.

Various modifications of this puzzle are possible. For instance, two or more puzzle boards may be. combined. 'When four are combined making onepuzzleboard consisting of four boardsas described above, in

the form of a square, cover cards can be provided havingtheir perforations arranged as combinations of the arrangements shown .inFigure 3, so that they may be applied to the puzzle board: in -any position with a similar result as obtained with the single board. v

A way of combining four puzzle boards in such a way to make the puzzle'more difiicult of solutiomisshown in Figures l6'to 19.

Figure 16 represents a puzzle board having in all SlXtYrfOUI- spaces for numbers, ar-- ranged in a square with eight spaces on each side; For the sake of olearness in nomenclature, we may consider this board asdivided into, four quadrants, each .quadrantflbeing divided into four quarter sections and each quarter, section into four spaces? The quarter sect ons'of this board arelettered,

each at its center, with letters placed to cor re -p nd w h a puzz e board. e lla teen numhepspa'ces as describedfabove,

Each of the quarter sections of the presb eor ep nds t e ingl um space of'thesixteen space board, asipreviously described, and the letters are, placed on said sections according to-the original key pat-tern, as describedfor such aboard.

The spaces of each quarter section are lettered with the same letters as applied to that section and in addition, are numbered to indicate their relative positions in that quarter section. Thus, the quarter section A, has four spaces A 1, A 2, A 3, and A l, and similarly for all the other quarter sections. The numbering of the spaces of each quarter section maybe determined as follows:

First, each space is given a letter corresponding to the letter of its quarter section. Next, a pattern is selected such as shown in Figure '17, which may be superimposed upon one quadrant of the board so as to discloseone space of each quarter section of that quadrant. In each space so disclosed, the number 1 is added to the symbol for that space, so that, for instance, the first spaces of the first quadrant will bear the symbols A 1, N 1, K 1, and H 1. The pattern may now be turned about the vertical center line of the board as an axis, (Figure 19) so as to lie upon the second quadrant of the board. It will now disclose one space of each quarter section as before. The spaces so disclosed are numbered'l, as before. The pattern may now be turned about the horizontal center line of the board as an axis so as to lie upon the third quadrant, and again the spaces disclosed are each numbered 1. The process is again repeated by turning the pattern about the vertical center line as an axis so as to lie upon the fourth quadrant, and the disclosed spaces are again numbered 1.

We now have sixteen spaces bearing symbols A 1, B 1, C- 1, etc., up to P l, and located in quarter sections arranged relatively to each other to correspond with the original key pattern. These numbered sections are furthermore located symmetrically with respectto the center of the board.

If the pattern is now turned about the horizontal center line of the board as an axis from its last position in the fourth quadrant. it will regain its first position in the first quadrant. The pattern may now be rotated about an axis through its center and perpendicular to the plane of the paper to a new position over the first quadrant and a new set of four spaces will be disclosed. These four spaces may now be numbered 2, so as to complete the symbols A 2, N 2, K 2 and H 2. The process of rotating the pattern successively about each of the center lines of the board, as described before, may now be repeated so as to complete the symbols of a second set of spaces A 2, B 2, C 2, etc., up to P. 2. we now have a second set of symbols placed in the quarter sections according to the ori inal key pattern.

By continuing this process, proper symbols maybe placed. in all of the spaces of the board, and we will have four'completc sets of symbols, each arranged on the board in the quarter sections according to the original key pattern. The pattern used in producing this arrangement may be varied by omitting some of the perforations, or shifting their location, provided that by so doing, no space in a quadrant is disclosed inmore than one position of the pattern.

The pattern shown in Figure 16 may be varied by rotating all of the quarter sections as described for Figures 12 to 15 inclusive. The numbers to be applied to the spaces are obtained by taking any four number sets, obtained as previously described, and applying one to each of the symbol sets A 1',B 1, etc., A. 2, B 2, etc., A 3, B 3, etc., A 4, B 4, etc.- Such number sets must, however, have the same values of W, X, Y and Z and in addition, the difference between P 1 and A 2 must be equal to the difference between P 3 and A a.

It will be seen that apuzzle is, therefore, produced which, when certain numbers are left out, will be very diilicult of solution.

Another type of cover card (Fig. 19) may be produced by arranging the perforations so as to disclose numbers similarly located in each of the four quadrants. By this is meant, an arrangement which would dis close, for instance, 1, 2 or 3 adjacent numbers in the upper left hand corner of each quadrant.

It is obvious that various changes may be made in the details of construction with out departing from the spirit of this invention; it is, therefore, to be understood that this invention is not to be limited. to the specific details shown and described.
