DESCRIPTION OF THE PREFERRED EMBODIMENT

[0027] Embodiments are described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense in that the scope of the present invention is defined only by the appended claims.

[0028] The numeral 10 refers to a squirrel-proof feeder which is illustrated in FIGS. 1-8. Bird feeder 10 includes a vertically disposed shroud 12 having an upper end 14 and a lower end 16. Shroud 12 is comprised of a mesh material having a plurality of openings 18 formed therein. A ring-shaped wall member 20 embraces the upper end of shroud 12 and is secured thereto by welding or any other convenient means and extends therearound as seen in the drawings. The upper end of wall member 20 has a pair of tabs 22 and 24 which extend horizontally inwardly from wall member 20 and which have screw openings 26 and 28 formed therein respectively. A horizontally disposed plate 30 is secured to the undersides of tabs 22 and 24 and extends therebetween. Screws secure the ends of plate 30 to the tabs 22 and 24. Plate 30 has a central opening 32 formed therein. The plate 30 may be omitted in some cases.

[0029] The numeral 34 refers to a cover which is secured to the upper end 14 of shroud 12 and/or the upper end of wall member 20 by welding or the like. In the embodiment shown, cover 34 is somewhat cone-shaped and has its lower outer end 36 positioned outwardly of wall member 20 and the upper end of shroud 12 and below the upper end of wall member 20 so as to shield the upper end of the shroud 12. Cover 34 has a frusto-conical shaped member 38 at its upper end with the member 38 having an opening 40 formed therein. Although it is preferred that cover 34 is generally cone-shaped, cover 34 may be flat.

[0030] Shroud 12 has a ring-shaped wall member 42 secured thereto by welding or any other convenient means. As seen, wall member 42 ernbraces shroud 12 above the lower end 16 of shroud 12. Wall member 42 could be replaced by a plurality of closely spaced wires or other structure extending around shroud 12. The lower end of shroud 12 has a plurality of radially spaced-apart perches 44 pivotally secured thereto. The perches 44 may not be pivotally secured to the lower end of shroud 12 but could be non-pivotal.

[0031] The numeral 46 refers to the one-piece feed container of this invention. Feed container is preferably of plastic construction and is transparent and has an upper end 48 and an inwardly tapered and open lower end 50. As seen, feed container 46 is positioned within shroud 12. A ring-shaped feed tray 52 is secured to the lower end 50 of feed container 46 by any convenient means. Feed tray 52 is configured to receive bird feed from the open lower end 50 of container 46 in conventional fashion. The outer end of feed tray 52 is positioned inwardly of the inside of shroud 12. As will be explained hereinafter, shroud 12 is vertically movable with respect to container 46 between upper and lower positions.

[0032] Feed container 46 includes a feed inlet structure 55 which is positioned within the upper end of feed container 46 and which is molded therewith. Feed inlet structure 55 has a plurality of feed inlet openings 56 formed therein to permit feed to pass downwardly therethrough to permit the feed container 46 to be filled with feed. The numeral 60 refers to a spring having an upper end 62 and a lower end 64. As seen, the lower end 64 of spring 60 engages the upper side of feed inlet structure 55. The upper end 62 of spring 60 operatively engages the underside of plate 30. The spring 60 yieldably urges shroud 12 upwardly to its upper position with respect to container 46 as will be described in more detail hereinafter. If the plate 30 is omitted, the upper end of spring 60 will operatively engage the underside of the cover 34. Spring 60 could be replaced with other springs such as seen in the co-pending application.

[0033] The numeral 66 refers to a vertically disposed hanger rod having an upper end 68 and a lower end 70. The lower end 70 of rod 66 is secured to feed inlet structure 55 by any convenient means. Rod 66 extends upwardly from feed inlet structure 55, through spring 60, through opening 32 in plate 30, and through opening 40 in member 38. A hanger support 72 is threadably secured to the upper end 68 of rod 66. A hanger loop 74 or other hanger device is secured to hanger support 72 for supporting the bird feeder 10 from some overhead supporting structure such as a tree, pole, etc. Although it is preferred that member 66 be a rod, member 66 could be a cable or other like member.

[0034] When it is desired to first place the bird feeder 10 into operation or to re-fill the feed container 46 with bird feed, the bird feeder 10 is placed upon a horizontal support surface such as the ground. The fitting 72 is then threadably disconnected from the upper end 68 of rod 66.

[0035] The shroud 12 and the cover 34, which is attached to shroud 12, are then moved upwardly with respect to feed container 46 and removed therefrom. Bird feed is then poured into the feed container 46 by way of the feed inlet structure 55. The bird feed passes downwardly through the feed openings 56 in feed inlet structure 55 into the interior of feed container 46 until the feed tray 52 and the feed container 46 are filled.

[0036] The shroud 12, with attached cover 34, is then lowered onto the feed container 46 with the rod 66 extending upwardly through spring 60, through opening 32 in plate 30 and through opening 40 in member 38. The fitting 72 is then threadably secured to the upper end of rod 66. The bird feeder 10 is then hung from an overhead support such as a tree, pole, etc.

[0037] When the seed container 46 is filled with bird feed and the feeder is hung from a support, the spring 60 will yieldably maintain shroud 12 in its upper position with respect to container 46 as seen in FIGS. 1 and 3. When the shroud 12 is in its upper position, the wall member 42 or other structure will be positioned above the openings 18 of shroud 12 which are outwardly of the feed tray 52 so that birds may perch on the perches 44 and have access to the feed in the feed tray 52. If a squirrel moves onto the shroud 12 or onto the perches 44, the weight of the squirrel overcomes the upward force of spring 60 which causes shroud 12 to move downwardly to its lower position with respect to container 46. The downward movement of shroud 12 to its lower position with respect to container 46 causes wall member 42 to be positioned outwardly of feed tray 52 thereby preventing the squirrel from having access to the feed in the feed tray 52 as seen in FIG. 8.

[0038] Thus it can be seen that the invention accomplishes at least all of its stated objectives.

[0039] Although the invention has been described in language that is specific to certain structures and methodological steps, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures and/or steps described. Rather, the specific aspects and steps are described as forms of implementing the claimed invention. Since many embodiments of the invention can be practiced without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
