Description

BIRD FEEDER WITH TOP RING

The present invention relates to bird feeders and improvements thereto.

The use of bird feeders is well known in the art. The feeding of birds, particularly during inclement weather, is widely practiced. Most of the bird feeders comprise a container which will house the seeds or other bird feed and allow for distribution of the seed to the birds at positions whereby they can feed.

Typically, the bird seed is allowed to feed by Gravity to a position proximate to one or more bird perches upon which the bird can land and eat the seed.

Many different types of seed feeders are known and one particular type includes that which is known as "squirrel proof'. These squirrel proof feeders incorporate a mechanism to prevent squirrels from feeding. Some of the mechanisms include weight sensitive technology which denies access to the seed when a weight above a certain predetermined amount lands on the perch. Other mechanisms use mechanical barriers such as baffles on poles.

When manufacturing the bird feeders, care must be taken that the weight sensitive mechanism either provides an adjustment or is predetermined and set by the factory. Adjustment of the spring tension would be desirable.

All bird feeders include one type or other of a perch on which the bird can land to 20 have access to the seed. A common type of perch is a stamped metal piece which is cut and stamped and the piece secured to the bird feeder. Frequently, the perches are uncomfortable for some birds who will not remain for very long on the perch.

A further problem is that squirrels will attempt to chew at the seed container to gain access to the seeds When a baffle is involved, the squirrels will attempt to use the baffle as a place where they can move on to an access field and without putting weight on the shroud.

A still further problem common to many bird feeders is the risk of spreading disease due to poorly maintained feed stations. The combination of moisture and seeds can result in the seeds becoming moldy or rancid. in order to obviate this problem, the feeders should be cleaned at a regular interval. This is frequently difficult to accomplish with the structure of many bird feeders. -2 -

In order to minimize the amount of cleaning required, it is desirable to minimize the access of rain or moisture to the interior of the feeder containing the seeds.

In order to minimize the amount of moisture, it would be desirable to have a deflector to deflect water running down the seed tube.

Most bird feeders will have a cover which is secured to the seed tube and generally a rotatable locking mechanism is utilized, it is frequently preferred that the cover is disengaged from the seed tube and put aside during the filling thereof. While providing access to the seed tube, a removable cover can present a problem as far as dropping or displacing of the same.

It is an object of the present invention to provide a novel arrangement for a cover for a bird feeder and a method of attaching the cover to the seed tube.

It is a further object of the present invention to provide a bird feeder which has an arrangement, for deflecting rain from flowing down the seed tube and moistening the feed within the seed tube.

Seed tube 12 defines a seed container having a cylindrical wall 28. Seed tube 12 has an open upper end 30 and an open lower end 32.

Located at open upper end 30 is an upper ring 34 which sits on seed tube 12.

Upper ring 34 includes a lower circular wall 36 and an upwardly tapering wall 38. Upper ring 34 also includes an upper side wall 40 which has protrusions 42 extending outwardly therefrom. Preferably, there are provided a pair of such protrusions 42 each being diametrically opposed to the other. A pair of recesses 44 are provided in upper side wall 40 for reasons which will become apparent he.reinbelow. Also, an upwardly extending wall 46 defines a slot 48. There are two such structures located on upper ring 34.

Cover 14, as may be seen In Figures 8 and 9, has a domed top wall 52 and a vertical side wall 54 extending downwardly therefrom. There is also provided a sloping wall 56 which terminates in a drip edge 58. Protrusions 60 are provided on the inner surface of vertical side wall 54. Preferably four such protrusions are provided. A pair of diametrically opposed protrusions 60 are designed to engage with protrusions 42 to hold the cover in position. A second pair of protrusions 60 engage within recesses 44 as is known in the art. Cover 14 also has a pair of recesses 62 formed in domed top wail 52 with an aperture 64 being located thereat.

Hanger 16 comprises a relatively stiff wire 68 Wire 68 passes through aperture 64 and is provided with an enlarged portion 70 which sits under upper ring 34 and is thereby retained in position in an alternative embodiment illustrated in Figures 15 and 16, wire 58 passes through cylindrical wall 28 with enlarged portion 70 retaining the wire.

Funnel 22, best illustrated in Figures 17 and 18, has an upper wall 76 with a plurality of protrusions 78 being formed thereon. Each protrusion 78 is designed to fit within an aperture formed in the bottom portion of cylindrical wall 28 of seed tube 12. To aid in locking and unlocking, a sloping ^,yall 80 is provided thereon.

Funnel 22 also has a lower wall 82 which is funnel shaped to help direct seeds as will be discussed hereinbelow. A middle wall section 84 extends downwardly from upper wall 76 and is spaced from lower wall 82. Threads 86 are provided on the interior of middle wail 84. A drainage member 68 extends outwardly from middle wall section 84 and has a U-shaped drainage channel 90 formed therein for reasons which will become apparent hereinbelow. It will be noted that there are gaps 92 between sections of middle wall section 84 to direct any water away from the feed openings.

Seed tube base 24, as may be seen in Figure 13, has an upper side wall 98 which has a plurality of threads 100 thereon. Threads 100 are designed to engage with threads 86 formed on middle wail section 84 of funnel 22. A plurality of feed openings 102 are provided in side wall 96 of seed tube base 24. As will be noted, there is provided a rim protrusion 104 which extends partially about the upper portion of feed openings 102. This arrangement allows rainwater to pass to the side of the feed openings 102.

Shroud 18 has a lower side wall 108 with a plurality of feed openings 110 therein.

An upper side wall 112 is directed to lower side wall 108. A baffle 114 extends circumferentially around the shroud and is located on upper side wall 112 such that it is above feed openings 110 to provide protection from the weather such as rain. It is obviously important that the baffle is located above the feed openings while also being close to the feed openings. An interior bottom wall has a plurality of drainage apertures 116 formed therein.

Located inwardly of the seed tube base is a longitudinally extending post generally designated by reference numeral 120. Post 120 is formed of a cylindrical wall 121 having a top wall 123. Located internally of post 120 is a rod 122 which has a flange 124 formed at the top end thereof. A lower portion 126 of rod 122 has screwthreads 128 formed thereon. Extending about rod 122 is a coil spring 130 which has a first end biased against top flange 124. An insert 132 is provided and is connected to the seed tube base by means of screws 134. A cap 136 is screwthreadedly engaged with lower portion 126 by screw-threaded engagement with screwthreads 128 Insert 132, as may be seen in Figure 7, has a cylindrical wall 152 which extends upwardly within post 120. Insert 132 also has a top wall 154 on cylindrical wall 152 and which top wall 154 functions as a stop to bias the lower end of coil spring 130.

An advantage of insert 132 is that it permits different sizing to be used to vary the compression of coil spring 130. Thus, if spring 130 happens to be of a different strength than normal, the length of cylindrical wall 152 may be varied. Insert 132 could also be used to vary the weight needed to move shroud 18 downwardly. -8 -

In the embodiment of Figure 4, rod 122 has an enlarged portion 123 at s upper end.

Stand 20; as seen in the drawings, also functions as a perch for the birds.

Stand or perch 20 is comprised of a plurality of circular elements 130 which extend completely around the shroud. In the illustrated embodiment, there are two such circular elements although more may be utilized if so desired. A plurality of radial elements 142 extend between and connect circular elements 140. A plurality of gaps 144 are formed by tins structure.

Each of circular elements 140 and radial elements 142 is designed to have a somewhat flat upper surface 146. On each side of upper surface 146, a pair of side walls 148 extend downwardly. The transition between upper surface 146 and side walls 148 is provided by arcuate corners 150 The arrangement is such that no sharp corners are present when the birds land on circular elements 140 or radial elements 142. The birds appear to be 15 more comfortable with this arrangement.

It will be understood that the above-described embodiment is for purposes of illustration and that changes and modifications may be made thereto without departing from the spirit and scope of the invention.
