PORTABLE WATER FEEDER

Abstract

A portable water feeder for collecting rain water for bees, butterflies and many other uses has a vessel in which rain water is collected. A filter removes impurities from the rain water and a wind-powered agitator maintains the water in motion to minimize the build-up of algae. A valve controls the quantity of water which flows from the vessel to a watering station where the water is available for use.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0019] With reference to FIGS. 1a and 1b, the water feeder of the invention, generally 10, comprises an array of cones, generally 11, at the top of the water feeder. Beneath the cones is a first or upper vessel 12, a second or intermediate vessel 14 beneath the upper vessel, a third vessel 15 for a float beneath the intermediate vessel and a tray or watering station 16 which forms the base of the water feeder. The four vessels and the tray or watering station are all in liquid-flow communication with each other and water cascades through each of the vessels entering the first vessel 12 and exiting from tray 16.

[0020] With reference to FIGS. 2a, b, each cone 18a, b in the array is attached by means of a ring 19a and a staple 19b to a separate arm 20 which extends radially outward from a circular plate 21 attached to a central shaft 22. The cones are hollow and have an open circular base 18a, a side wall 18b which tapers to an end 18c. A small aperture 18d is formed in the cone adjacent to end 18c through which the air from the wind exits. The cones function to catch the wind which strikes the water feeder and cause shaft 22 to rotate.

[0021] Shaft 22 is mounted in bearings within a housing 24 to rotate about a vertical axis. The shaft extends downward from the array of cones and terminates at a horizontally extending bar 26 within the intermediate vessel 14. Paddies or vanes 28 are attached to opposite ends of the bar and function to keep the water within the vessel in motion.

[0022] The cones and paddles constitute an agitator and function to minimize the growth of algae in the water. Wind may be the prime mover for the agitator but other means may be employed for that purpose. For example a battery activated motor may serve to activate the agitator when the wind is too weak to do so.

[0023] With reference to FIGS. 1a and 3, the upper vessel 12 has a cone shaped or frustum shaped upper wall 30 which tapers upwardly and terminates at housing 24. The upper wall is in the form of a screen for admitting water from rain or from other sources such as municipal water or a well. The screen also serves both to prevent insects from entering the vessel and to minimize the amount of dust in the air from entering the vessel. Because of the shape of the cone, less water evaporates from the vessel than would be the case if it were flat. The cone-shape also functions to catch rain water which the wind causes to flow in various directions over the upper wall such as horizontally, vertically and obliquely.

[0024] The side wall 12a of the upper vessel is solid and tapers downward to a central orifice or opening 12b through which water flows downward into the intermediate vessel 14. The upper and intermediate vessels 12, 14 are interconnected by straps 36 which are connected at its upper end to a rim 12d on the upper vessel and on its lower end to a flange 14a on the intermediate vessel.

[0025] With reference to FIG. 4a, the level of the water within the vessel can be determined by a conventional transparent graduated tube 40 which is spaced apart from the vessel and extends its height. Water flows into the tube through an opening and an elbow 42 near the bottom the vessel. tWxcess watr in the vessel is drained off through overflow port 38.

[0026] With reference to FIGS. 4b and 5a, beneath the intermediate vessel is the float-containing vessel 15. The two vessels are interconnected by tabs 71 which are attached to vessel 15 and frictionally engage vessel 14. The bottom wall 14b of the intermediate vessel is solid but for a central orifice through which water discharges into the vessel 15. The quantity of water which discharges is controlled by a float valve assembly which includes a water inlet tube 50 having a threaded stem 50a and a hexagonal nut 54 at its lower end. The stern extends through the orifice and is immobilized by an upper hexagonal nut 52. Both nuts 52 and 54 are threadably attached to the stern and are tightened together to ensure that the inlet tube is secured to wall bottom 14b. Gaskets or washers 56 minimizes leakage of water around the edges of the nuts.

[0027] Beneath the inlet tube is a valve guide 58 which is provided with a number of longitudinal ribs or tongues 58a which are slidingly received in the cylindrical central inner hollow in inlet tube 50, At the bottom of the valve guide is a circular base 58b which contacts a like shaped valve support 60. The support has a downwardly extending stem 60a which is internally threaded for receipt of a threaded adjustment rod 62.

[0028] The adjustment rod extends downwardly and through a central opening in a float 66. The float is sandwiched between lower and upper plates 67, 68 respectively which are threadably attached to the adjustment rod.

[0029] In operation, and with reference to FIGS. 5a and 5b, the level of water in the float-containing vessel 15 measures the level of the float. In FIG. 5a, the float is at the maximum elevation. At that elevation, the base 58b of the valve guide is in contact with hex nut 54 and no further upward movement of the float is possible. As the level of water in vessel 15 recedes, the float likewise descends with resulting downward sliding of the ribbed area of the valve guide in the central hollow of the inlet tube. Downward movement of the float ends when clip 70 contacts the top of the valve guide.

[0030] Since the central hollow in the inlet tube is cylindrical and the valve guide is ribbed, there is space between the ribs for water to flow downwardly from the intermediate vessel 14 into the float-containing vessel 15. The water continues to flow until the water in the vessel 15 supports the float sufficiently to bring the base 58b of the valve guide into contact with hex nut 54.

[0031] To summarize, in FIG. 5a the valve is closed and no water discharges from vessel 14 while in FIG. 5b, the valve is open and water discharges into vessel 15.

[0032] By means of adjustment rod 62, the position of the valve guide and the float on the adjustment rod can be adjusted by rotating the backing plate 60 or the lower and upper plates 67, 68 respectively on the rod with resulting adjustment in the maximum level of water within the vessel. An overflow port 72 is provided in vessel 15.

[0033] With reference to FIGS. 5b and 6, water from vessel 15 discharges through orifices or openings 80 in the side wall of the vessel into tray or watering station 16 which defines the upper wall of the base. The tray has a rim 82a which prevents water from overflowing the tray. A notch 82b is formed in the rim for water to discharge from the tray should it be over-filled.

[0034] As has been explained above, the water feeder of the invention is composed of a number of individual vessels which are arranged one below another and that rain water flows through orifices from one vessel to the next in line. Since the orifices constricts the flow, there is turbulence in the water and this turbulence supplements the turbulence caused by the agitator. The turbulence caused by the orifices is produced entirely without the necessity of an external source of power to cause it.

[0035] To facilitate periodic cleaning of the tray, a depression 84 is provided so that the tray may be drained dry at that time through tap 86. The tap may be closed to prevent water in the tray from draining from the tray at other times.

[0036] If the water feeder of the invention is intended to provide water for bees, it is advisable to have a layer of gravel or stones 88 on the tray on which bees can rest while drinking to minimize the risk that they will drown at that time.

[0037] It will be understood that modifications can be made in the water feeder of the invention without departing from the scope and purview of the invention as defined in the appended claims.
