564,631. Model building blocks. ROBINS, T. H. May 11, 1944, No. 7535/43. [Class 132 (iii)] Model building blocks are provided with holes 10 whereby they may be connected by split ferrules, Fig. 6A. The blocks may be of full, Fig. 1, or half-thickness, Fig. 10, and may have square or rounded ends. As shown in Fig. 9, a number of blocks may be secured by a bolt 24 with nuts 23. The bolt may serve as a hinge for a door 38, Fig. 18. Thin metal strips, Fig. 22, of various forms, may be used to hold the blocks in fixed position, e.g. in making bay windows or roofs. A block may have a groove 16, Fig. 2B, for co-operation with a rib 49 on a special window unit, Fig. 27. Special roofing units, Fig. 29, may be interlocked, the apex being held by a capping unit 64, and the bottom supported by a gutter 56, Fig. 28, secured by a pin to a ceiling 58. The blocks may be arcuate in shape, whereby a model locomotive can be made. The blocks may be made in halves of moulded synthetic resin, and cemented together or held by rivets 78, Fig. 3A.
