Abstract: A construction set comprising components for building a temporary miniature structure, intended to enable and encourage young architects to build toy building structures of recognizable conventional appearance as they choose. The set comprises structural components of easily distinguishable shapes; and of various sizes, to make it simple for each young builder to design his or her own structure. Most importantly, all components, for safety purposes, are of a size which is too large for the builder to swallow. In a structure, building blocks are fit together by morise and tenon effect, and corner members are held by mortise and tenon effect in an opposite direction to provide suitable security. A roof member is easily held in place by small, adaptable mortise and tenon effect The provision of side members of various sizes enable the builder to construct window and door openings wherever he or she wishes.

Abstract: A portable tree trimming device comprising a pruning mechanism secured at a distal end of a telescopically extendible housing. The pruning mechanism includes cutting members exterior of the housing drivable by a motor within the housing. The motor receives current furnished thru a coiled cable within the housing receiving power from either a domestic electric source or from a battery unit positioned within the housing. The coiled cable extends and protracts in unison with extension and protraction of the extendible housing.
