  • Patent number: 4365819
    Abstract: A stroller for transporting a doll when pushed or pulled by a child has a pair of wheels secured to and rotatable with a horizontal axle, a right angle gear transmission from the axle to a vertical central shaft which is rotated when the stroller is propelled forward or backward. The top end of the vertical shaft is secured to and passes through the center of a frame formed as a seat for receiving and holding at least one doll. Rotation of the wheels when the stroller is pulled or pushed causes corresponding rotation of the vertical shaft and the canopy and the seat and doll therein.

  • Patent number: 4349987
    Abstract: A robot doll with an internal drive unit for automatically causing the doll in prone face-down position to bend at the waist until reaching a semi-erect position, then to straighten-up to a standing position, and then to wobble from side-to-side, or to simulate walking, and/or to fall down. A first switch actuates the doll to move from prone position to standing. A reversing switch, actuated as the doll stands, reverses the drive motor to complete standing action. A rod is reciprocated in and out of at least one foot to simulate walking actions and to cause the doll to tip. An interior frame carrying an electric motor and gears is loosely mounted and a cam mounted thereon causes the frame, hence the doll, to wobble while in the standing position. The doll eventually falls from standing position and impacts its pivoted arms on the support surface. This opens a reversing switch and starts the series of moves over again.

  • Patent number: 4101607
    Abstract: A vessel with means for aerating a liquid therein, and particularly a bait bucket for containing water and live bait and means for replenishing oxygen in the water. The vessel has an upper chamber for containing the liquid, with a vent comprising a small aperture at the bottom of this chamber for allowing the liquid to slowly drip downward into a second closed chamber containing air or other selected gas. As the liquid occupies more of the space in the second chamber, the pressure of the gas in the lower chamber increases until a small quantity of gas escapes through the orifice, forms gas bubbles and rises through the liquid in the upper chamber. This gas flow is intermittent and will continue for many hours.

  • Patent number: 3991507
    Abstract: A leader holder which provides an elongated corrugated shell axially compressible in a bellows-like manner along a series of alternating raised and lowered circumferential protrusions and depressions. Each of the depressions are separated from an adjacent protrusion by a continuous circumferential surface, each surface including a plurality of spaced apertures positioned about the length of the circumferential surface. The apertures are adapted to hold a length of leader therein, each of the leaders being contained entirely within one of the circumferential surface areas in an individual depression. A case is adapted to encase the shell, and to do so in a manner maintaining the shell in its axially compressible state.

  • Patent number: 3947989
    Abstract: A fishing lure or teaser that is constructed with a hollow cylindrical body and a shaped front end portion. The cylindrical body includes a removable plug positioned opposite the shaped end portion and held in place by means of a retaining shaft or other means. The plug includes means for retaining a plurality of streamers. The hollow cylinder includes a series of spaced ribs along the length thereof protruding inwardly. Positioned internally against the ribs is a sheet of light-controlled film which exhibits a varied color characteristic in accordance with light incident thereon. The hollow cylindrical body is fillable with liquid such as water for effecting the buoyancy thereof while in use and transmits the reflective index and qualities of the light-controlled film more effectively. The retaining shaft includes means for fixably attaching a hook or like member for securing an attracted fish.
