Abstract: The sound-of-steam producing system is completely mounted on the tender intended to be pulled by a toy electric locomotive. The system includes a switch mechanism included in the circuit of a module which energizes a speaker to simulate the puffing sound of a real locomotive. The switch mechanism is opened and closed by a roller mechanism comprising a pair of rollers having their diameters ratioed in accordance with the relative diameters of the locomotive's drive wheels and the tender's wheels, whereby the puffing sound is precisely synchronized with the rotation of drive wheels of the locomotive.

Abstract: The manipulator includes an internally toothed ring, an externally toothed wheel, and a cam arm. The wheel and arm, which function in a "master" capacity, have registerable holes for accommodating the tip of a ballpoint pen so that a primary line design is created as the ballpoint pen is manually moved over a sheet of paper while maintaining the wheel teeth in mesh with the ring teeth. The ring has at least one pivot post projecting upwardly into a slot in the cam arm to cause the cam arm to function in a "slave" capacity so that a fiber-tipped pen gripped by the cam arm produces a secondary line design at the same time the primary line design is being produced.

Abstract: A resilient U-shaped steel band has its upper ends adjustably attached by means of slotted angle irons to a rigid saddle composed of a panel of fiberboard and a strip of plywood secured thereto. A bottom plate overlies the horizontal section of the band. Fabric sheet material constitutes the outer cover for the luggage being stitched to the fiberboard. A relatively heavy fabric belt is stitched to the cover along the edges of the band, thereby providing a sheath for the band and preventing transverse shifting thereto.

Abstract: Prismatic blocks having a triangular cross section are provided with letters and scoring numerals on two faces thereof. In forming words, the players position the blocks in a grid having rectangular openings therein so that only one of the lettered faces is visible. The scoring numeral on one face of each block is contained in a box, whereas the scoring numeral on the other lettered face is unboxed. The highest score wins the game. However, the players can earn extra or bonus points by combining the blocks in prescribed patterns, such as words of at least a certain length containing all boxed numerals or all unboxed numerals.
