The invention relates to building lumber for fabricating toy structures, and has for an object to provide building lumber which can be readily assembled and interfitted by children to produce toy buildings, fences and other structures.
Another object of the invention is to provide a building block or slab which is corrugated on one face to simulate logs and which is fiat on the opposite face, the edges of the block having jointforming parts adapted to frictionally interfit with i the mating parts of other building elements.
The invention further consists in the several j features hereinafter described andclaimed. In the accompanying drawings,

Fig. 17 is a side view of another form of build- T ing element.
In these drawings, 20 designates one form of building element, which is shown in detail in Figs.
3 and 4, and which consists of a rectangular plate-like block or slab, preferably of wood, having a flat inner face 2| and a corrugated outer face 22. The corrugated face carries a plurality of rounded parallel beads 23 extending longitudinally of the block and simulating logs. The opposite side edges of the block are formed with a tongue 24 and a groove 25 respectively, both extending longitudinally of the block. The opposite end edges of the block are provided with a' tenon 26 and a mortise 21, respectively, preferably arranged substantially midway between the tongued and grooved edges. At one end of the block the tenon projects beyond both of the corresponding ends of the tongued and grooved edges, and the other end of the block has at its corners projecting tenon-like parts onto which the tongued and grooved edges extend. Preferably, the effective length of the block is twice the effective width of the block, excluding the tongue 24 and the tenon 26. A rectangular block 28 is similar to the block 20, but has only onehalf the effective length of the latter block. The edges of the blocks 20 and 28 are adapted to frictionally interfit with the mating edges of similar blocks, or of other'building elements hereinafter described. 7
A block 29 (Figs. 2 and 15) is similar to the block 20 but is provided with a rectangular notch 30 in one side edge simulating a door or window opening- A block 3| (Fig. 5) is similar to the a block' 20 but has an intermediate rectangular opening 32 to frictionally receive the tenon of another block. A block 33 (Fig. 6) is similar to the block 20 but is provided with intermediate rectangular notches or mortises 3G in opposite edges to frictionally receive the forked mortised end of another block. The blocks 3| and 33 permit the use of other blocks forming partition walls, as indicated in Fig. 16. A block 35 is similar to theblock 28 but has a port hole 36 l and is suitable for use in the block house shown in Fig. 2.
Several wall-forming blocks with diagonal edges are provided forsupporting roof panels. As seen in Fig. 1, a trapezoidal block 31 is surmounted by a small triangular block 38 to form a triangular wall section. If desired, a window notch 39 may be formed in the block 31. The span of the block 3'! is here indicated to be one and one-half times the length of the block 20. The sloping edges of the blocks 3'! and 38 are at an angle of 45 to the horizontal. A triangular block 40, used in the mill building of Fig. 14, is similar to the triangular panel formed by the blocks 31 and 33 and has a span substantially equal to the length of the block 2E].
For supporting roof panels of less slope, as seen in Fig. 15, other triangular blocks are employed. A block shown in detail in Fig. 17, is used in the building shown in Fig. 15, and may have a window opening '62. The span of the block 4| is substantially one and one-half times the length of the block 20, and the height of the block is substantially equal to the width of the block 20. Tongues 24' extend along the lower edge of the block M to be frictionally received in the grooves of subjacent blocks.
For supporting the lean-to roof of the cabin of Fig. 15, there are used triangular blocks 43 and 44 shown in detail in Figs. 7 and 8. Each of these blocks has substantially the same length and heigh as the block 29. The blocks 13 and 94 are provided with a tenon 2S and a mortise 21', respectively, to interfit with other wall-forming blocks. The blocks 43 and 44 are also capable of fitting together endwise to form a long span wall section. The lower edges of the blocks 53 and 44 are formed with tongues 24".
The roof panels of the cabin of Fig. l are formed by fitting together edgewise a number of the blocks 29 and 28, the laterally adjacent blocks being staggered. The length of each slope of the roof is made up by one block 20 interfitting end- Wise with one block 28. In the mill of Fig. 14, one end of the roof carries a rectangular frame made from four of the short blocks 28, the upper two of which interfit with the side edges of the end blocks of the roof. Four of the blocks 29 interfit with side edges of the frame blocks 28 to simulate a wind wheel. A chimney block 55 has a V-notch 49 by which it can be saddled over the ridge of any one of the cabin roofs.
The mortise and tenon joints between the ends of the blocks 29 or similar blocks are such that the interfitting blocks can be placed in alignment or in angular relation. The short blocks 28 can be used as swingable doors, as indicated in Figs. 1, 14, and 15. The width of the mortise 21 of the block 29 or similar block is one-half the width of the block, and the effective width of each of the tenon-like parts on opposite sides of the mortise is one-quarter the width of the block, or one-half the width of the mortise 21 or tenon 26. When two of the blocks are assembled edge-to-edge by the tongue-and-groove joints, the adjacent tenon-like parts of the two blocks combine to form a full-width composite tenon, so as to permit symmetrical patterns to be produced both in composite panels and at building corners. The full-width composite tenon thus formed will frictionally fit in either the corresponding composite mortise formed at the ends of a pair of similar edgewise-connected blocks, or in the mortise 21 of the block 29 or similar block.
Fence posts 41, 48, and 49 are provided to cooperate with the blocks, especially the short blocks 28, for the construction of a fence, as seen in Figs. 1 and 15. The post 41 is of square crosssection and has a vertical groove 59 on one side and a vertical tongue on an adjacent side. The post 48 has vertical grooves 59 on adjacent sides and a rectangular notch or mortise 52 on another side, the mortise having the same width as the block tenon 26. The post 49 has vertical tongues 5! on adjacent sides and a tenon 53 on another side, the tenon having the same Width as the mortise 52. The blocks 28 are set vertically to simulate a picket fence and interfit with each other and with the fence posts 97, 48, and 49, as seen in Figs. 1 and 15. Another block 28 is disposed as a gate between the fence posts 48 and 49 and has its opposite ends interfitting with the mortise 52 and tenon 53. The gate-forming block may be swung on one of these posts. The posts 48 and 49 may also be interfitted with the blocks 28 or blocks 26 when these blocks form part of a building wall.
In the block house of Fig. 2, four of the short blocks 28 are assembled in a square wall frame to form a base section, and four of the similar blocks 35 form a similar wall frame interfitting with the upper edges of the blocks 28. The tongues of the blocks 35 are uppermost and fit in cross grooves 54 formed in the bottom face of a square platform 55, which overhangs the frame of blocks 35. The upper face of the platform has cross grooves 5'5 therein to receive the tongues of four of the blocks 29 assembled into a square wall frame. The frame of blocks 29 is surmounted by a pyramidal roof section 51. In the present instance one corner of the roof section is cut away to admit a square wall frame of the blocks 35, the tongues of two of these blocks entering the grooves of two of the blocks 29. The uppermost wall frame of blocks 35 is surmounted by a pyramidal roof section 58 carrying a flag staff 59.
In assembling the various blocks into panels for the walls and roofs of the buildings, the blocks are preferably placed flatwise on a table or other support and fitted together, and the panels are then placed in upright position to be interfitted with companion panels. The relation of the tongues, grooves, tenons, and mortises on the blocks is such that when any two of the rectangular blocks are interfitted end to end with the corrugated faces thereof at the same side, the tongues thereof will be at the same edge of the assembly, so as to insure the proper fitting of additional pieces to the several edges of the assembly. Because of the position of the mortises and tenons at the ends of the blocks 29 and similar blocks, it is possible to form building corners with superposed blocks, and also ridged roofs, without need for transversely notching either the tongued or grooved edges of the blocks.
What I claim as new and desire to secure by Letters Patent is:
1. A building to-y comprising a pair of rectangular plate-like wall-forming blocks, two opposite edges of each block having a tenon and a mortise respectively to interfit with the complementary edges of the other block, and two other opposite edges of each block having tongue-andgroove parts, a side of at least one of said blocks being apertured at an intermediate portion to interfit with one of the mortise and tenon edges of the other block, said blocks when thus selectivelylinterfitted edge-to-edge or edge-to-slde having their tongue-and-groove edges in flush relation.
2. A toy building element comprising a substantially rectangular plate-like block two opposite parallel edges of which are tongued and grooved longitudinally of the block to frictionally interfit with the mating edges of similar blocks, and two other opposite edges of which respectively have a tenon and a mortise to frictionally interfit with the complementary mating mortised and tenoned edges of similar aligned and angularly extending blocks, said tenon at one end of the block projecting beyond the ends of the tongued and grooved edges, and the other end of the block having at its corners projecting tenon-like parts onto which said tongued and grooved edges extend, a pair of said blocks when interfitted edge-to-edge by their tongued and grooved edges having their adjacent tenon-like parts forming a composite tenon at one end adapted for engagement in a corresponding composite mortise formed at an end of a pair of similarly interfitte-d blocks.
