" ’ ' In the following description and in the claims, various details will be identiñed by speciñc names for convenience, but they are intended to be as v A top piece 30 (see Fig. 5) is formed from stock. which preferably is similar to the stock forming'4 the liner members 20a and 20h and is similarly“ provided with a wrapper 3|. The top piece 3U is' dimensioned similarly to the top sections 24 ofthe liner members 20a and 20h. Referring to Fig. 6, the block is assembled by folding one of the liner members 20a` along the fold lines 2| and 22 With the wrapper 26 on the inner side whereby the liner member assumes a generally U-shaped form. The top piece 30 is then disposed on the bottom panel 24. 'I‘here after, the liner member 20h is set up in a similar manner to the first liner member 20a and is dis generic in their application as the art will per posed `on top of the top piece 30 but rotated 90° mit.

'I‘he block consists essentially of a heavy outer shell of tubular formV and one or more liner mem bers disposed within the shell and serving to close one end of the tubular shell and reinforce the side walls thereof; usually, a Wrapper is applied 30 to the block for improving the attractiveness. Referring particularly to Fig. 1, the shell is liner members 20a and 20b lying against the inner faces of the panels I, 2, 3 and 4 of the 25 shell I5. Referring to Fig. '7, it will be seen that the block as thus far assembled has four side walls formed of two-ply material, the total thickness of which is approximately three times the thick ness of the liner piece. `The wall which is per formed preferably from a single blank 5 of rela pendicular to the side Walls, and designated here in, for convenience, as the “top” or “end” wall, board, ñbreboard or the like. The blank may be is of approximately equal.thickness to the side formed of stock of any desired thickness, but I ` Walls but'is constituted of three plys of material, 35 have found that a stock ranging from about à; namely, the two top panels o-f the liner members to about 1/8 of an inch suitable for many sizes of 20a and 20h _and the’top piece 30. The liner blocks. A plurality of relatively deep 90° grooves members 20a and 20h and the top piece 30 may tivelyv heavy material, as for example, paper v or cuts 6, 'I and 8 are formed in the blank and 40 divide it into side panels I, 2, 3 >and 4. The end be secured in the shell I5 by applying an adhe sive to the side panels 23 and 25 preferably be edges 9 and IIJ are beveled at 45° whereby to pro fore the liner members and top piece are inserted vide a mitered corner when the blank is set up. in the shell I5. Preferably, the sides of the grooves 6, 1 and 8 and the beveled edges 9 and III extend through out the major portion of the thickness of the blank, but‘sumcient material is left to provide a Itwill be seen that the side panels 23 and 25 olfA the liner members 20b iit inside of the side flexible connection between the panels, along the grooves 6, 'I and 8. l The blank 5 is set upto form a tubular shell by bending the sections at right angles about the lines 6, 'I and 8 and bringing the beveled edges 9 and I0 into abutment, as shown particularly in Fig. 6. The abutting edges of the side panels I and 4 are secured in a suitable manner, as for 55 example, by the adhesively attached thereby forming a tubular shell` I5. strip I4, ' " panels `23 and 25 of the liner member 2üa. Hence, when the liner members are inserted in the shell I5, and secured thereto, there is an interlocking of the liner members at the corners of`> theA block and the structure is more rigid than if "the Wallsïwere merely individually laminated. 4The blanks, employed in forming the liner . members 20a and 20h and the blank forming the shell I5, are cut from material in such a way that when the block is assembled, the fibres or> “grain” of the material inthe side panels 23 and _Referring Anow to Fig. 3, a liner member 20a 25 of each of the liner members extend or run perpendicular of the fibres or grain in the cor is formed from a rectangular blank, such as responding panels of the shell I5. Thus, when paperboard, which preferably generally is of less 60 er thickness than the shell blank. For example, the block is assembled and the liner members are secured to the shell, an extremely stiff, rigid block is provided. The top- wall and side walls are ofV substantially equal thickness and are formed of laminated members having the grain the liner blank may be approximately one-half the thickness of the shell blank. 'I‘he liner blank is provided with spaced score’lines 2I and 22 which divide the blank into side sections 23 and 25 and an intermediate top or “end” section 24. The liner blank may be formed of stock which is suitably calenderedv and/or colored on at least ' extending in perpendicular directions, hence the wallsL have _substantially equal rigidity and are substantially equally rigid both longitudinally and laterally. , Thus, the block is not weak in any one side thereof, but preferably the blank is cut direction but is capable of withstanding shocks from stock having a wrapper 26 of calendered- or stresses applied from any direction. and/or colored material secured to one face In this connection it will be noted that when thereof. Y ’ the liner members 20a and 20h are assembled, Preferably, two identicalfliner;'members 20al the grain of the end'panel 24 of the liner mem and Zlibv are provided, for apurposeV which will berV 20b`extendsperpendicularly to the grain of `ihereinafter appeanthe second` linerv member 20h theîcorresponding portion of the liner member being shown in Fig. 4. 20a. Thus, the top wall of the block likewise arenas-asi. has increased; rigidity, by: reason. of the perpene dicularity of the» fibres. in the;la_minations- _ofîthe Wall. » 1', ' , It; Willz be, noted that: the. cutì lines L20,w |,2¿|~,Y - The block preferably is. provided'iwith. a; suitUl able covering or lWrapper. and/or liner which may» befof plain. color, a. contrasting color with thev Wrappers: on the liner pieces or. which may be» decorated. with; designs, indicia', scenes. or» the like, as iscustomary in- toy blocks.
