Abstract
Abstract A bird feeder having a cup-like container for the bird seed, a vertical central shaft to support the container, a bent rod attached to the vertical shaft for hanging the bird feeder from a window frame (or other support), and a lid attached to the bent rod and spaced slightly above the container to protect the seed from the weather and to keep out large birds. The bird feeder''s central shaft carries a horizontal plate, such as a washer, to support the seed container and to prevent tipping. Also, a locking member is fitted to both the central shaft and the bent rod to prevent the bird feeder from swinging or otherwise moving despite the weight or activities of the birds.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
224 words
A bird feeder comprising: a. a cup-like hollow seed container having an open top and a substantially centered bottom hole; b. a vertical central shaft inserted upwardly through the bottom hole in said seed container, said central shaft having support means associated therewith for cooperating with the bottom of said seed container to resist downward axial movement and axial tipping of said seed container relative to said central shaft; c. said central shaft having a substantially horizontal hole formed transversely therethrough, the hole being located above the lower end of said shaft; d. a bent rod-like mounting element having a substantially horizontal free end inserted through said horizontal shaft hole, said rod-like mounting element further having a substantially vertical middle portion positioned substantially parallel to said central shaft, said rod-like mounting element further having means associated with its other end for engaging a fixed support from which the bird feeder is suspendably mounted; e. locking means for retaining said rod-like mounting element free end in said shaft hole and for retaining said rod-like mounting element middle portion in substantially parallel alignment with said central shaft; and f. a lid having a vertical hole through which said other end of said rod-like mounting element is inserted, said lid being positioned in a substantially horizontal attitude and being spaced above said top of said seed container.
Claim 2
Dependent Claim
224 words
A bird feeder comprising: a. a cup-like hollow seed container having an open top and a substantially centered bottom hole; b. a vertical central shaft inserted upwardly through the bottom hole in said seed container, said central shaft having support means associated therewith for cooperating with the bottom of said seed container to resist downward axial movement and axial tipping of said seed container relative to said central shaft; c. said central shaft having a substantially horizontal hole formed transversely therethrough, the hole being located above the lower end of said shaft; d. a bent rod-like mounting element having a substantially horizontal free end inserted through said horizontal shaft hole, said rod-like mounting element further having a substantially vertical middle portion positioned substantially parallel to said central shaft, said rod-like mounting element further having means associated with its other end for engaging a fixed support from which the bird feeder is suspendably mounted; e. locking means for retaining said rod-like mounting element free end in said shaft hole and for retaining said rod-like mounting element middle portion in substantially parallel alignment with said central shaft; and f. a lid having a vertical hole through which said other end of said rod-like mounting element is inserted, said lid being positioned in a substantially horizontal attitude and being spaced above said top of said seed container.
Claim 3
Dependent Claim
43 words
The bird feeder of claim 1 wherein said seed container bottom support means includes an enlarged portion formed on the lower end of said shaft and a washer carried by said shaft between said enlarged portion and the bottom of said seed container.
Claim 4
Dependent Claim
