Abstract
A bird feeder having a lid latching mechanism which comprises L-shaped holes on the feeder's lid, and a wire handle having projections that orient above the lid. The projections in the handle align with the sides of the L-shaped holes to prevent the lid from being lifted from the bird feeder. A seed cover over the seed dispensing area is connected to a shaped wire perch via a through-hole. The perch acts as an actuator to close the seed cover, and is counter actuated by an extension spring, which attaches to the seed cover and feeder base.
Claims3
A bird feeder comprising:
- a) a base having a floor and sides
- b) a seed column attached to, or formed from the sides of said base
- c) a seed dispensing area
- d) a lid having two apertures with each aperture comprising two rectangular sections connected in a perpendicular orientation, whereby forming an L-shape
- e) a wire handle having two projections that comprise bends
- f) a means for latching said lid, whereby the wire handle goes through the apertures on the lid with said projections being oriented above the lid to align with the sides of the apertures to prevent the lid from lifting
- g) trunnion holes in the sides of said base
- h) an extension spring
- i) a shaped wire perch/actuator
- j) pivot holes in the sides of said base for attaching said perch actuator
- k) a plurality of attachment points for said extension spring in the side of said base, whereby spring resistance can be adjusted
- l) a seed cover having trunnion tabs, an attachment point for said extension spring, and a through hole for said perch/actuator at the bottom corner,
- m) a means to prevent a squirrel from accessing said seed dispensing area, whereby a squirrel's weight on the perch/actuator caused the seed cover to pivot to a closed position over the seed dispensing area.
