l n, if

My invention relates to provements in educational toy blocks for teaching children to select and put together articles of different sizes, shapes,

and colors, in like or different sizes and color combinations and, incidentally, testing their aptitude as regards perception of size, color and shape.

Other and subordinate objects, within the purview of my invention, together. with the precise nature of my improvements will be readily understood when the succeeding description and claims are read with reference to the drawing accompanying and forming part of this specification.

In said drawing: V

Figure 1 is a view in perspective illustrating my invention in a preferred embodiment thereof;

Figure 2 is a view in vertical longitudinal section;

Figure 3 is a view in perspective of a modification of the invention; and

Figure 4 is a similar view of another modification of the invention.

Referring to the drawing by numerals, according to my invention as illustrated in Figures 1 and 2, an elongated rectangular, flat, base block I is provided with a plurality of top, threaded cylindrical sockets 2 in the longitudinal center thereof spaced apart equidistantly, preferably, and of the same diameter, preferably although not necessarily.

A set of cylindrical blocks 3 of the same size are provided for stacking n the base block I with the blocks attached together in the stack and to said base block. For this purpose, the blocks 3 are provided with axial threaded bores 4 preferably of the same size, in diameter, as one of the sockets 2. Screw plugs 5 are provided, one for turning into one socket 2 to extend out of the same so that one block 3 may be threaded thereon, and the others for turning into the bores 4 of subjacent blocks 3 in the stack to project above such V blocks for the attachment of the blocks together in stacked concentric formation.

Another set of rectangular successively smaller blocks 6, I, 8 are provided for stacking on the base'block I. This set of blocks is designed to be stacked with smaller blocks on top of larger blocks with the stack attached to the base block I and the blocks of the stack attached together by the following means. Stepped bores 9 are provided in the center of these blocks 6, 1 with larger Screw 'A pplication M ytw, 19ras iama2aj612 :"1o1aim. (01535-73) eter, are provided, one for turning into one of the sockets 2 to project out of the same for turning of the larger end of the bore In of the larger block 6 onto the same to secure said block to the base block land the others for turning into the smaller ends of the bores 9 to project out of the same for turning of the larger ends of successively smaller blocks 1, 8 thereon to secure the blocks of the set together.

In the modification of the invention illustrated in Figure 3, a cruciform shaped block is provided with a central bottom screw plug l3 fast thereto for turning into one of the sockets 2, and also with a top central threaded socket M for turning into the same a screw plug on another similar block so that such blocks may also be secured together in stacked formation with the stack attached to the base block I.

In the modification of the invention shown in Figure i, a rectangular block I5 is provided with a bottom screw plug l6 and a top threaded socket l'i like the screw plug l3 and socket [4 of the cruciform block l8 of Figure 3 and for the same purpose, and said block I5 is provided with threaded side sockets l9 for attachment of other similar blocks to the sides thereof by the screw plugs 16 thereof.

All of the set of blocks may be colored differently, respectively, for arrangement in stacked formation in corresponding colors in the stack, but, it has not been deemed necessary to illustrate the blocks as colored. 7

As will now be seen, the blocks of my invention and the means for attaching the same together and to the base block I are especially designed to teach attaching articles together in like or dif- The foregoing will, it is believed, suflice to,

impart a clear understanding of my invention, without further explanation. I

Manifestly, the invention, as described, is susceptible of modification, without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claim.

Having described the invention, what is claimed as new is:

A set of educational and intelligence testing blocks for children comprising an elongated base block, sets of blocks for stacking on said base block, the blocks in one set being alike, and the blocks in the other set being difierently shaped than the biocksiof the iset first-r'nentioned and of successively smallersize in-the set, like devices of the same size and character for securing each block of the first-mentioned set to a lower block in the stack and the lowermost blockvof-"the stack to said base block, and devices fofsbufing each block of the second-mentioned set -to -a lower block of the stack and the lowermostblo ck oi the stack to the base block comprisii'ig lilie"devices-- of different sizes relatively, whereby to teach'cl'iildren the difierence between like and unlike articles and the difference between articles of different sizes.
