Specification of Letters Patent.

Application filed ma 1920. Serial No. 378,279.

T all whom it may concern:

Be it known that 1, Former K. MILLARD, a citizen of the United States, and a resi- .dent'of -l?ittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a ,new and Improved Puzzle, of which the following is a description.

The general object of my invention is to provide a sectional puzzle made up of a definite number of sections of given shapes, whereby the given task of solving the puzzle may be varied within limits to add to the interest of the puzzle. j

The nature of the invention will clearly appear from the specificrdescription followmg. 7 I s 1 Reference is to be had to the accompanying drawings forming apart of this specification, it being understood that the draw: ings are merely illustrative of one example of the invention.

Figure 1 is a plan view of a sectional puzzle embodying elements formed in accordance with my invention and arranged to forma square;

Fig. 2 represents on a reduced scale another square formed by the same elements differently arranged; v

Fig. 3 represents two figures formed from my improved sectional elements, the two figures jointly employing all the elements of the puzzle;

Fig. 4 is a plan view of another figure that may be formed from my improved puzzle by employing all the elements thereof;

Fig. 5 represents in plan and side elevation one of the elements of my improved puzzle.

In carrying out my invention I employ fifteen separate elements servin to jointly make up the sectional puzzle. fitIlOHS solutions of my improved sectional puzzle are possible; the four solutions illustrated as examples will be particularly referred to in the following:

All the elements present a series of squares of equal size and adjacent squares are distinguished from each other by suitable means. In the illustrated example I distinguish a square or squares of a given element from the other square or squares of said element by a circle. The arrangement i such that when the sections are properly assembled to jointly make up a figure rep-' resenting a given solution of the puzzle, squares of the respective elements will be disposed in the complete figure in amanner that those squares similarly distinguished will alternate. The squares in each element are defined by surface lines in conjunction with the defining edges of the element.

Patented June "2,1921.

The total of fifteen sections orfelem ents'i are employed to conipose the puzzle and these are respectively designated in the assemblage of Fig. 1 by the numerals 11 to 25, inclusive. i l

Four L-shaped elements numbered 11, 12,

15 and 19 each presenting three squares are employed, some of said elements presenting two squares similarly distinguished (by the circlefor example) and a single square otherwise distinguished as by leaving the same plain, while in others of the said four L-shaped elements two squares remain plain and unmarked while the third is distinguished by the particular means adopted, such as the circle. The other elements of the puzzle are sisfollows: An L-shaped element presenting five squares, of which four are in line; one element, 22, presenting five squares of which four are disposed in the form of a Tand one at one end of the T- head and at the opposite side from that square constituting the shank of the T; one element, 20, presenting four squares arranged in the form of a square, and a fifth square at one side of one of the said four squares; two elements, 13 and 1 1, of T-shape presenting four squares, that is, three in the head of the T, and one representing the shank of the T; one element, 17, presenting six squares of which four are in a row, .and two at the sides of the two intermediate squares in said row of four; one element, 24, presenting four squares in a row and the fifth square at a side of one of the squares and disposed next to an end square; three elements, 16, 21, and 25, presenting four squares disposed in two overlapping rows of two squares each; and finally, one element 23 presenting four squares in a row' and two squares at one side of said row,

said two squares beingspaced the distance i zle is afforded by Fig. 3, wherein two figures a e sh h on (at the left of Fi 3) made up of the elements 15, (or 11) '16, (or 21); 18; 19, (or 12); 22; and 25 (or 21); while the figure atthe right of Fig. 3 is similar to thatat the left except that it has two additional, and longer rows of squares at the center, said figure at the right of Fig. 3 being made up ofthe elements as follows: 11. (or 12; 13; 14; 17; 20; 21; 23 and 24.

In ig. at a further example is given of a figpre employing all the elements (1 to 25 V V Fig. 5 is yen to show one of the sectional elements to wit; No. 25, which, as stated, 5

corresponds with 16 and 21 in shape.

I would state in conclusion that while the illustrated example constitutes; a prac of equal size and defined jointly by surface. lines and the marginal edges of the respective elements, adjacent squares being dietin guished, said elements presenting members puzzle comprising fifteen ele-i and surface squares positioned to variously receive different members and squares of others of said elements 1n a varlety oi distlnctlve assemblages, sald elements comprising thefollowing to wit; four Lsha-ped elements each presenting three squares; three elements each presenting four squares disposed in two overlapping rows of two squares each; two elements of T-shape presenting four squares; one L-Shaped element presentmg five squares of which four are in line; one element presenting five squares of wh ch four are disposed as a T and one at one end of the T-head and at the opposite side from that square constituting the shank of the T; one element presenting four squares arranged' as a square and a fifth squareat one side of one vof the, said four squares; one element presenting six squares of which four are in a row and two at one side of said row alongsidethe two intermediate squares insaidrow; one element presenting four squares: in a row and a fifth square at a side of one of the squares disr posed next to an end squarein said row;

and one element presenting four squares in a row and two squares at oneside of the row said two squares being spaced the distance of one square and one of the two being adjacent to an end of said row.
