DEVICE FOR SEGTIONAL CONSTRUCTION.

Application filed September 2, 1924. Serial No. 735,385.

To all whom it may} amera: Figure 6, a symmetrical design produced Be it known that I, RAYMOND L. KURTZ, by a different interlocking arrangement of citizen of the United States, residing at sect-ions of the type shown in Figures 1 Denver, in the county of Denver and State and 2; of Colorado, have invented certain new and Figure 7, an assembly of sections of simiuseful Improvements in Devices for Seclar character bearing letters arranged to tional Construction, of which the following form a word; is a specification.

' lockingrelation;- f InFigure 5, for example, the middle sec:

tion is disposed at right angles to the outer section while in Figure 7 a number of sec tions are arranged with their edges in parallel relation to each other.

The sections of the last mentioned figure are provided with letters and the sections are so arranged that their letters spell the Word schools.

It will be seen that in this manner the pupils are taught the rudiments of word construction at the same time that their artistic sense is developed by the symmetrical arrangement of the sections on which the let ters are printed.

Section bearing numerals may be used in a similar manner to form numbers or sums or by providing the sections with other symbols or markings, pictures or ornamental and fanciful designs may be produced by the proper arrangementof the sections in either predetermined or arbitrary relation.

In Figure 6 has been shown a number of sections arranged and interlocked to form two squares at right angles to each other, the squares being interwoven so that they form conjointly a complete article, the parts of which are integrally connected.

An article of this kind may be used for ornamental purposes or it may have a useful object, it being apparent that in the manner shown doi li'es, mats and other similar objects may be constructed in a large variety of designs.

By connecting the end sections of a success'ion of sections :as shown in Figure 1, a picture frame or na/pk-in ring may be constructed, or by an arrangement of different parts each composed of a plurality of the sections and interlocked by inserting the protruding corners of their end or edge sections through each others slits, baskets, lamp shades and other devices too numerous to be separately mentioned, may be pro duced.

Now referring to the form of the invention illustrated in Figures 5 and l, the sections each have one or more pairs of slits 6 extending obliquely in opposite directions from an :intemnedi ate point in the perimetric edge of the article.

The slits of each .pair may meet on the edge of the section as in the form shown in Figure or they may beseparate from each other by an intermediate portion of said edge as indicated in Figure 11.

The double slits which preferably are formed at opposite edges of the section permit of a still larger variety .of designs in assembling the sections and by inserting portions of one section through. both slits at one side; of another -.section, the sections may be interwovenlinto-an article of great rigidity. v

As: stated. iheizeinloefe e, he design and articles that can be made are innumerable, the articles produced may be ornamental only and used for decorative purposes or they may be useful as avell as ornamental, thereby placing the invention in a class outside of that relating merely to educational appliances. However, it is as a medium of instruction that my invention is of particular value since it develops and stimulates the faculties or artistic conception and constructive ingenuity as a natural adjunct to a pleasurable occupation and without perceptible effort on the part of the student.

Having thus described my invention, What I claim and desire to secure by Letters Patent is:

1. A device for sectional construction comprising normally loose and separated pieces of pliable material slitted at and obliquely to their perimetric edges, for their interlocking connection.

2. A device for sectional construction comprising normally loose and separated pieces of pliable material slitted' in opposite directions relative to intermediate points in their perimetric edges for their interlocking connection.

3. A device for sectional constrnctioncomprising normally loose and separated pieces of pliable material each having oppositely disposed slits at and obliquely to its perimetric edges, for their interlocking connection.

4. A device for sectional construction comprising normally loose and separated pieces of pliable material each having oppositely disposed pairs of slits for their interlocking connection, the slits of each pair diverging relative-to an intermediate point in the perimetric edge of the respective piece.

5. As a new article of manufacture for sectional construction, a piece of pliable material having a pair of slits diverging 0bliquely from a common point in its perimetric edge.

6. A device for sectional construction comprising normally loose and separated geo metrically formed pieces of pliable material slitted at and obliquely .to their ,perimetric edges for their interlocking connection.

7. As a new article of manufacture for sectional construction, a normally loose .piece of pliable material, perimetrically square, slitted at and obliquely to an edge thereof for its interlocking connection nitl' another similar piece.

8. As a new article of manufacture for sectionalicon truetioinanornia ly loos of pliable material, periinet-ricall s are slitted at and obliquely to opposite edges thereof-for its interlocking connection with other similar pieces.

.9. .Aspa .new article of manufacture for sectional construction, anormally -loose;pieee f pliable a t p rennially quar and having at one edge, a pair of diverging slits for its interlocking connection with another similar piece.

10. As a new article of manufacture for sectional construction a normally loose piece of pliable material, perimetrically square, and having at opposite edges, pairs of diverging slits for its interlocking connection With other similar pieces.

11. An article of sectional construction composed of normally loose and separated sections slit-ted at and obliquely to their perimetric edges and interlocked by insertion of a part of one section through a slit of another section.

12. An article of sectional construction composed of normally loose and separated sections having pairs of diverging slits at their peripheral edges and interwoven by insertion of a part of one section through a pair of slits of another section.

In testimony whereof I have afiixed my signature.

RAYMOND L. KURTZ.
