CUBE BOX.

SPECIFICATION forming part Of Letters Patent NO. 508,298, dated November 7, 1893. Application filed June 22, B93. Serial No. 478.527. (No model.)

To all whom it may concern.-

Be it known that I, NEWTON Z. FULTON, of Gunniso'n, in the county of Gunnison and State of Colorado, have invented a new and useful Improvement in Cube Boxes, of which the following is a specification.

My invention is in the nature of an educational appliance for the purpose of demonstrating plane and solid geometry, and to this end it consists in a cubical shaped box designed to receive and act as a receptacle for the various models of plane and solid geometric forms such as cylinders, conesf'cubes pyramids, globes, squares, triangles, ellipses, parallelograms, 850., and having also on the outer walls of three sides of said boxhinged sections which when folded form a perfect cube of larger size than the box, and which sides have also other hinged sections which by their movable character serve to illustrate the principles of square and cube root by the segregable character of one of the aliquot parts of said square or cube, all as hereinafter fully described.

Figure 1 is a view in perspective of the box the device with its hinged section opened and 'with a portion of the box broken away to show the storage within the same of various other geometric forms.

In the drawings A represents the box or receptable which is a perfect cube with equal sides. Within this box or receptacle are contained the various other geometric forms used for illustrating plane and solid geometry such as the cylinder, globe, cube, pyramid, cone, square, triangle, ellipse, parallelogram, &c. The top F of this box is made to fit down within the sides of the box so as to be flush with their upper edges, and is provided with hinges a at one side, and a flush or non proj ecting handle or pull b. To each of the three sides of the box at one of their edges is hinged a folding section, which are all of the same size, and correspond in square dimension to the sides of the box. The top folding section B is hinged at one side to the upper horizontal edge of the box, and has also hinged to it in turn at its free edge a smaller supplemental section B whose length is the same as one of the side sections 13, and whose cross section is a perfect square.

0 isone of the side folding sections. The square dimensions thereof are equal to one of the sides of the box, and it is hinged at c to one of the vertical edges of the same, and in turn has hinged to its upper edge another supplemental section 0 equal in length to the side of the box, anda square in cross section.

D is the third of the side folding sections. Like the others its square dimensions are equal to those of the side of the box, and itis hinged at d to one of the vertical edges of the box, and has attached to its free edge a supplemental section D whose length is equal to the side of the section and whose cross section is a square. To the end of this supplemental section D is hinged a further supplemental section D which is a perfect cube with all square sides equal to the cross section of all the supplemental sections B O D. When all of these hinged sections are folded about the box they make a perfect cube, and when unfolded, as in Fig. 2, they illustrate the analysis of the cube into its aliquot parts of which D is one, and this serves to illustrate square and 7 cube root in the following way: Supposing the top of the closed box to be divided into aliquot parts, of which D is one, and there are six of these aliquot parts in each row, and six rowsof them, it will be plain that there will be thirty six aliquot parts similar in size to D and the square root of thirty-six will be six or the'number of times that such number must be multiplied by itself to equal thirty six. aliquot space so that six corresponding areas will lie under each aliquot section D we will have thirty six multiplied six times to make two hundred and sixteen, the cube root of which is six or the number which multiplied by itself and the product then multiplied again by itself equals two hundred and six teen. In this way, owing to the segregable character of the parts, ocular demonstration of square and cube root is clearly and forcibly given, and yet the parts are all connected together and are not capable of being detached and lost.

As the device is made of sufiicient size to act as a receptacle for other detached geometric forms within, the hinged sections all are secured by catches e, and an external handle E is provided so that the device maybe conven- Now measuring down from each iently transported without opening and spilling its contents.

I am aware that a small and solid cube has been provided with supplemental folding sections corresponding in the main to .my sections B C D D and I do not claim this broadly. My invention is distinguished by the fact that it is constructed as a box or receptacle of considerable size with flush lid and handle for the storage of geometric forms, and by the fact that the hinged sections are provided with locking devices and a main supporting handle.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The cube box herein described consisting of a hollow receptacle made in the form of a cube with an adjustable flush door or lid; combined with three hinged folding external sections of the same square dimensions as the box having supplemental hinged sections equal in length to sides of the box and of square cross section, one of said supplemental folding sectionsbein g provided with a hinged block forming a perfect cube whose square is equal to the square cross section of the supplemental hinged sections, substantially as and for the purpose described.

2. The cube box herein described consisting of a hollow receptacle made in the form of a cube with an adjustable flush door or lid;

combined with three hinged folding external sections of the same square dimensions as the box two of said hinged sections having a supplemental folding section on their free edges parallel to the hinges, and the third section having a folding supplemental section on its edge at right angles to its hinged edge, and one of said hinged supplemental sections having a hinged cube whose square equals the cross section of the supplemental sections substantially as and for the purpose described.

3. The cube box herein described consisting of a hollow receptacle made in the form of a cube with an adjustable flush door or lid; combined with three hinged and folding sections of the same square dimensions as the box, and having supplemental hinged sections equal in length to the sides of the box and of square cross section, one of said supplemental folding sections being provided with a hinged block or cube whose square is equal to that of the cross sections of the supplemental hinged sections, catches or fastenings for holding these hinged sections in locked position, and a handle for lifting and transporting the entire device substantially as and for the purpose described.
