DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new and improved automatic funnel embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

More specifically, the automatic funnel 10 of the instant invention essentially comprises a conical frontal body 11, having an exit tube 12 extending therefrom in fluid communication with the funnel body, wherein the exit tube 12 is of a predetermined tube diameter and has an exit tube lowermost end 13 in surrounding relationship about an exit tube exit end. An annular groove 14 (see FIG. 2a) is directed into the exit tube 12 in adjacency to the lowermost end 13. A mesh web pocket 15 is provided, including a pocket annular entrance ring 16, having a ring annular projection 17 arranged for reception within the annular groove 14 of resilient construction for securement of the mesh web pocket 15 to the exit tube 12 extending and projecting therebeyond and therebelow, with a buoyant sphere 18 mounted within the mesh web pocket whereupon filling of a container, the buoyant sphere extends into the exit tube exit end opening to effect blockage thereof and provide for fluid filling within the exit tube and frontal body for visual indication of ample fluid within a container (not shown) to filled.

The FIG. 5 indicates the use of an exit tube annular seat 19 positioned within the exit tube 12, with a door 20 provided, having a door hinge 21 arranged for directing the door 20 over the annular seal 19 in fluid impermeable communication therewith, wherein a tether line 22 having its first end secured to the door 20 spaced from the hinge 21 includes a second end secured to a U-shaped spring clip 23 arranged for mounting to the entrance periphery of the funnel tube 11, as indicated in FIG. 6. The U-shaped spring clip 23 includes clip first and second legs 24 and 25 respectively, with the second clip 25 including a leg projecting 26 in facing relationship medially of the first leg 24 to effect spacing of the door 20 from the seat 19, with projection of the clip fully onto the seat, as indicated in FIG. 6, permitting closure of the door, in a manner as indicated in FIG. 5. A U-shaped clip entrance end 27 provides ease of directing the clip structure onto the periphery of the funnel body 11.

The FIGS. 7 and 8 includes a central leg 28 mounted within the exit tube in facing relationship relative to the lowermost end 13 for abutment with the buoyant sphere 18 when the buoyant sphere is in contiguous communication with the exit tube outlet opening, such that the central leg 28 is in electrical communication with an audible alarm 29 having a self-included battery 29 to effect actuation of the audible alarm 29 upon the central leg 20 engaging the buoyant sphere. A body cavity 30 mounted to the funnel body 11 at the annular entrance periphery provides spaced orientation of the audible alarm to provide for such maximum spacing preventing fluid communication with the body cavity 30 during a filling procedure. It should be understood that a simple DC circuit may be employed, whereupon the central leg 28 is operative with a switch to effect electrical communication of the audible alarm 29 relative to its included battery.
