  • Patent number: 4441256
    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.

  • Patent number: 4383386
    Abstract: A battery powered toy in the form of a skillet has a simulated cooking surface of dielectric material containing thereon a grid of electrically conductive strips which are normally electrically insulated from each other by reason of the dielectric cooking surface that exists between the strips. When a deformable material, such as Play-Doh.RTM. brand modeling compound, having a sufficiently low electrical conductivity is kneaded or cut into the shape of an article of food and is manually placed on the cooking surface so as to bridge or span portions of the electrically conductive strips constituting the grid, the deformable material completes a circuit that activates a noise signal generator which produces through the agency of a small speaker a sizzling sound resembling that of frying food.

  • Patent number: 4185413
    Abstract: A toy milkable figure representative of an animal of the type capable of dispensing milk. The figure has a pivotally mounted head which may be pushed downwardly from an upper position to a lower position where a mouth opening in the head is immersed in liquid. The figure has a pivotally mounted tail which may be pumped up and down to create a liquid pumping action. The figure has an udder that forms a liquid holding chamber and has one or more flexible and squeezable teats. When the head is lowered into the liquid supply and the tail pumped, liquid is drawn into the mouth opening and delivered into the udder chamber. A liquid intake limiting mechanism causes the head to automatically raise out of the liquid after a predetermined amount of pumping.
