  • Patent number: 4848702
    Abstract: An aero marine vehicle having a fuselage having front wings extending from its respective left and right sides. Engines are mounted in these wings and their drive propellers are supported adjacent the rear edge of these wings. A pair of laterally spaced hull members are supported beneath the respective right and left wings. A plenum chamber is formed in each of the hull members with the bottom wall of the hull members forming the bottom wall of the plenum chambers. Exhaust lines are connected between the engines and the respective plenum chambers. The bottom wall of the hull members has a plurality of exhaust ports formed therein which allow the escaping exhaust gases to form a boundary layer of air between the bottom wall of the hull members and the water they are floating upon to overcome the suck-down effect of the water upon the hull member. The majority portion of the interior of the hull members form a buoyancy chamber.

  • Patent number: 4821452
    Abstract: A snail trap in the form of a housing having a dome-shaped top wall with cylindrical side walls extending downwardly therefrom. A plurality of snail entry archways are formed around the circumference of the side walls. A plurality of legs extend downwardly from the side walls for anchoring the snail trap in the ground. In actual use, a liquid or paste type of snail insecticide is first applied to the bottom surface of the ceiling of the dome as a toxic bait for slugs and snails. The snail trap is then placed on the ground and its legs are pushed into the soil up to the bottom of the archways.

  • Patent number: 4815709
    Abstract: The winch has a disc-shaped hub having a shaft extending upwardly from its top surface. It also has a winch drum having an axial bore whose diameter is sized to rotatably receive the shaft of the disc-shaped hub. The bottom end of the winch drum has a recess with ratchet teeth formed around its inner annular surface and there are a pair of pawl members in spring loaded attachment with the outer surface of the shaft of the disc-shaped hub to form a ratchet assembly. There is a bore hole in the bottom end of the disc-shaped hub and an upright extending secondary shaft member has its top end rotatably inserted into this bore hole. A handle has its one end secured to the secondary shaft and it extends radially therefrom and has a supporting block mounted on its opposite end and a double cam cleat is mounted thereon. An alternative form of handle is also operable with the same basic winch structure but does not require the handle to be permanently secured to the winch.

  • Patent number: 4813252
    Abstract: A locking device for firearms that allows the firearms to be openly displayed, yet safe from the hands of inquisitive children. The device is formed from an elongated rod member that has been formed into an open loop configuration whose free ends are directed toward each other and have a predetermined open space between their tips. The rod member is inserted into the eyelet portion of an eyebolt that has been threaded into a corner stud of a room. Two portions of the open loop configuration of the rod member are oriented at 90 degree angles to each other and these aligned horizontally and in mating relationship to the respective corner walls to which the eyebolt has been secured. Either of the free ends of the rod member is threaded through the trigger guard of a rifle or revolver to secure the firearm to the locking device.

  • Patent number: 4778428
    Abstract: A flying saucer toy having a pair of LED's mounted diametrically opposed to each other on the rim of its disc-shaped body. The LED's are electrically connected to a printed circuit board and batteries which allow the LED's to strobe imperceptably fast at approximately 100 Hz. A touch-sensitive switch has three terminal posts that extend through the top surface of the disc-shaped body and the bottom ends of the terminal posts are soldered to the circuit board to form a mounting structure for the circuit board. When the flying saucer toy is thrown at night the strobing effect will produce the effect of more than twenty lighted points around the disc perimeter depending upon the rotational speed of the disc.

  • Patent number: 4774869
    Abstract: A multi-flag marching baton formed from an elongated tubular sleeve within which an elongated member is telescopically received. There is a space between the inside wall surface of the tubular sleeve and the outer surface of the elongated member to form an annularly shaped flag storage chamber. A strap passes along the outside length of the tubular sleeve and has its opposite ends attached adjacent one end of the elongated member. A first display flag is secured to this strap. A second display strap is secured to the elongated member. When the elongated member is telescopically withdrawn from one end of the tubular sleeve, the second flag will be withdrawn from the flag storage chamber within the tubular sleeve and unfurled for display while at the same time the first display flag that is attached to the strap will be drawn into the opposite end of the tubular sleeve and its flag compressed into the flag storage chamber.
