This invention relates to an educational play device particularly adapted. for young er persons, wherein a number of builder boards are provided, having openings therein, the,openings being relatedto the edgesxof all boards, and-the spacing of the openings on all boards being such that the boards may be connected together edge to edge, and in co-planar or angular relation,

1 in innumerable combinations, for jforming various full size or miniature structures, such as tables, chairs, bookcases, closets,

kitchen cabinets, doll houses, etc.

,.An..object is to provide for the building of substantially full size Wooden- Structures from aplurality of board sections, of dif ferent sizes, said sections adapted to, beconnected. edge in co-planar relation, such a variety of sizes of boards being had, as will permit plural piece sections or lengths of large size or areato be constructed from smaller sizes whereby comparatively large and useful structurescan beyproduced. I

. The device further provides a plurality of 1 connectors. or tie pieces, having openings therein spaced in correspondence to the spacing. of theadjacent' openings, and to the inward; spacing of the rows. of openings from the edge of the boards, so that;tlie

openingsof the connectors .canbe, ;madeto use'tuln'ess, particularly forchildren of,-all

ages and sizes.

Although the rectangular form of board is; preferred as being more, simple, and thus more; suitable in the education of younger children, as for. example, those in the kindergarten yet theinventive idea canbe appl1ed,;to boards havlng any regular :geo-

metric figure, wherein the inward spacing of. the-openings as Wellv as the spacing betweenconsecutwe openings canbe made-to -.pr.oper1y. correspond .in all boards. The

larger sets as used at present, include ninety boards, one hundred angle irons, fifty fiat connectors, and three hundred bolts with the winged nuts. I Y

In the embodiment illustrated, each rectangular board has adjacent each of its four sides, spaced inwardly therefrom and panel lel therewith, a straight row of openings 7 between adjacent members of herein being consecutively related as the sides of a rectangle." The spacing of the rows inwardly from the sides of the boards and linear spacing from center to center of adjacent openings, is the same for all boards, whereby the boards may be arranged in angular or co-planar relation in many combinations, and connected edge to edge in such co-planar or angular relations, by the use of connector straps or connector angle pieces, and the bolts 13 with their complementary wing nuts.

The dimensional relation of the members of the set is regular, or in other words, the pieces' have a fixed dimensional ratio to one another, so that by selecting and securing together in co-planar relation the proper combinations of smaller pieces, 'a large plural piece board, of a size corresponding to one of the large single piece'boards, can be produced, (see Figure 6). Thus the smaller pieces'can be utilized for the production of a desired larger single fiat piece (see Figure 6), and likewise larger built-up plural piece boards can be produced and attached in angular relation to large single piece boards.

The smallest board,-1 of the set herein illustrated, has a dimension of 5x 10", the ratio of the length of the sides being as one to two, and this board has eight openings therein equally spaced apart from center to center and each of the four rows spaced inwardly the same distance from a corresponding edge. The next larger board 2 is 5 x 20", a ratio of one to four, and has sixteen openings therein. The next larger board 3 is 5x 30", a'ratio of one to six, and has twenty-four openings In this series of three boards, the width of all boards is the same, with the lengths consecutively increased, and the consecutively larger boards are respectively two and three times the length of the smallest board.

In the second series of three boards, the size of the first board 4, is 10 x 10", a ratio of one to one, and has twelve openings. The second board 5 is 10 x 20, a ratio of one to two and has twenty openings, the size of the third board 6 is 10 x 30", a ratio of one to three, and has twenty-eight openings. In this series, also, the width of all boards is the same but the length is increased, and the consecutively larger boards are respectively two and three times longer than that of the smaller.

The ratio of the widths of the series are as one to two, or five inches to ten inches. In both series, the increase of the number of openings of consecutive larger members over the preceding, is eight. Moreover, the difference in number of openings between corresponding members of the two series, is four.

I claim as my invention:

1. A device of the class described comprising a plurality of boards each having only four rows of openings, said openings extending through the board fromoneface side of greatest area to the other end in the same direction, a row parallel with each side, the spacing between consecutively related openings ofall boards being equal and the rows of all boards being spaced the same distance inwardly. i

2. A device of the class described com-1 prising a plurality of boards each having only four rows of openings, said openings extending through the board in the same direction, a row parallel with each side, the spacing between consecutively'related openings of all boards being equal and the rows of all boards being spaced the same distance direction, a row parallel with each side,'the

spacing between consecutively related openings of all boards being equal and the rows of all boards being spaced the same distance inwardly the inward spacing of the rows being one-half of that between consecutive openings, and metal straps, having two-openings spaced apart twice the distanceof the inward spacing of the rows, adapted to connect the boards in coplanar edge to edge relation. H

4. A device of the class described com prising two series of rectangular boards the members of each series having dimensions which are simple multiples of each other and of the'members of both series, each board having only four rows of openings all extending in the same direction, a row parallel with each side, the space between consecutively related openings of all boards being equal, and the rows of all boards spaced the same distance inwardly from the edges.-

5. A device of the class described comprising plurality of boards each'having only four rows of openings, said openings extending through the board in the same direction, a row parallel with each side, the spacing between consecutively related openings of all boards being equal and the rows 7 of all boards being spaced the same distance inwardly the inward spacing of the rows being one-half oi that between consecutive openings and angle irons each having an opening in each leg, each opening spaced from the corner a distance equal to the inward spacing of: the rows, said irons adapted to connect the boards in right angular relation.

6. A device of the class described com prising two series of rectangular boards the members of each series having dimensions which are simple multiples of each other and of the members of both series, each board having only four rows of openings all extending in the same direction, a row parallel with each side, the space between consecutively related openings of all boards being equal, and the rows of all boards spaced the same distance inwardly from the edges, the inward spacing of therows being one-half of that between consecutive openings, and the number of openings in consecutively larger boards of each member of each of the series being increased by eight openings.

7. A device of the class described comprising members of each series having dimensions which are simple multiples of each other and of the members of both series, each board having only four rows of openings all extending in the same direction, a row parallel with each side, the space between consecutively related openings of all boards being equal, and the rows of all boards spaced the same distance inwardly from the edges, the

inward spacing of the rows being one-half ol'that between consecutive openings, and the number of openings in consecutlvely larger boards of each member of each of the series being increased by eight openings and connector plates and angle irons having openings therein adapted to register with the board openings for attaching the boards edge to edge in coplanar relation, or "for attaching them at rightangles to one another.

In witness whereof, I have hereunto set my hand this 29th day of April, 1926.

ELIZABETH M. WALKER.
