  • Patent number: 4159590
    Abstract: A trap has a body having an end formed with a first opening. Rotatably mounted on the end is a closure shaped with a second opening. The closure has an open position with the openings aligned so the animal may enter the body and a closed position with the closure blocking the first opening to prevent escape. The closure is releaseably held in open position by a pin slideably mounted in the end passing through a hole in the closure. Bait in the body is connected by a cord to the pin so that when an animal attempts to carry off the bait the pin is pulled out of the hole and the closure pivots to closed position. A treadle may be mounted inside the body and connected to the cord. When an animal steps on the treadle it pivots to pull the cord away from the end to pull the pin as an alternative way to close the trap. Counterbalancing of the closure and of the treadle make the triggering of the closure very sensitive.

  • Patent number: 4019462
    Abstract: For transportation and storage the device is made of detachable components which are easily assembled without use of special tools. Three platforms, preferably circular, are held horizontal by at least one vertical post fitting through holes in the platforms. Fastening means engaging the post or posts hold the platforms horizontal and vertically spaced. Surrounding the two lower platforms and supported by dowels in the edges thereof are wires which function as perches. Edgings around the lower platforms prevent the contents from falling to the ground. On top of the upper platform is a pan and depending from its lower surface is a circular skirt which protects the contents of the lower platforms from being washed away by rain. The plan on the top functions as a bird bath. One of the lower platforms contains bird seed and the other gravel or other items on which birds feed. A hummingbird feeder may hang below the lowest platform.
