21 Claims.
My invention relates to improvements in drip valves.
The object'of myinvention is to. provide means for. enabling fowls to. supply themselves with pure water from a protected reservoir or other source ofv supply.
A further object is to prevent the withdrawal of excess water, while enabling the fowls to pick it inindividual dropsfrom positions of suspension,.and to-withdraw it from the reservoir substantially in proportion to their needs and not materially in excess of needs, whereby waste of water and the wetting of: the surrounding premises may be avoided.
Inthe followingv description, reference is had to the accompanying drawings, in which:
Fig 1 is a perspective view ofa poultry drinking fountain containing a plural set of drip valves embodying my invention.
Fig. 2 is an elevation of one of the drip valves, drawn to an enlargedscale.
Fig. 3 is a sectional view drawn to line 3-3 of Fi 2.
Fig. 4 is a detail view of the male valve member in tilted position, fragments of the body and valve seat member'being' shown in vertical section.
Fig. 5 is a detail, partly'in' elevation and partly in vertical section, showing a modification.
Like parts are'identified by'the same reference characters throughout the several views.
My improved drip-valve-has a' body- I provided with a'threadedsocket l I at its upper end, and a central vertical bore i2 leading downwardly through the body from the bottom of the socket. A- tubular member His-fitted-to thebore and provided with a conical valve seat It at its lower end. The upper end of the member l3'extends into the socket H and is provided with a head 15; exteriorly threaded", asshown in Fig. 3.
The body is supported from a water supply pipe by means of a coupling member 11 which has a stem-like extension [8 at its lower end. It it exteriorly threaded forengagement in the socket H, and interiorlythreaded for engagement with a thread on the headed end I of the member 13. The upper end of this coupling member is provided with an exterior thread IQ for engagement withthe supply pipe 20.
The body Ill has a. sleeve like depending portion 21' through which .the. bore I2 extends, and annularly spaced: therefrom isa depending skirt 22. .0! greater length. A spring. supported valve member 23: has an annular shoulder 24 which seats against the lower .end'of thesleeve-like extension 2 l, the latter having its lowerend notched as shown at 2|. The valve member 23 has its upper end provided with a needle-like extension 25 which loosely enters conical valve seat [4, but is more sharply tapered and, therefore, adapted to be tilted as shown in Fig. 4. Near its point it is in closeproximity to the seat l4 along a circular line and a water seal tends to form along this line, although the parts are out of actual contact. They are held out of contact by the lower end of the sleeve-like extension 2!.
The valve member 23 has a supporting stem 28 provided with a neck 29 and a head 3!) at its lower end, upon which a drop of water may collect, as indicated at St in Fig. 2. A spring 3'2 is coiled around the neck 29 and connected with the skirt 22 at 33. the upper end ofthe spring being preferably received in the annular socket 34 between the skirt 22 and the sleeve-like extension 2|. The skirt 22 protects the upper end of the spring and limits tilting movement of the valve.
Normally the spring holds the valve 23 with its annular shoulder 24- in contact with the lower end of the sleeve-like extension 21, with the needle-like projection 25 slightly retracted from thevalve seat IA. The needle valve contact is so close that a film of water tends to form a seal along the-line of closest approachand prevents dripping if the pressure of the water is insufllcient to overcome the upward urge of the spring. Ifthe film is. dislodged, a drop of water will escape and pass downwardly over the valve to the'head 30 where it will tend to collect in the form of a suspendedtdrop. If the water does not so escape, a light lateral pressure applied to the head 30 will cause the valve to tilt, or fulcrum on the lower end .of member 2 thereby slightly withdrawing the needle-like extension 25 from the seat [4 and permitting the escape of additional water from the passage 25 in the member [3. Sufficient lateral pressure for this purpose will be exerted whenever one of the fowls picks at the head 30. The latter preferably will be provided with a semi-spherical glass knob 35-, sufiicientlysuggestive of a drop of water suspended from the head 38 to induce the fowls to pick it.
My improved drip'valve may be connected with any suitable source of water supply under light pressure. It Fig.1 I have illustrated a set of four of these drip valves, each connected by a pipe 2'! with a supply main 4!}. leading from a reservoir 41, supported by a shelf 42- from the interior surface of the wall-43 ofabuilding or chicken coop.
Also, in Fig. l I have illustrated a disk 44 suspended by a rod 435 from an end cap 46 on the supply main 4!]. The disk 4:3 has its upper surface dished toward an opening 41 communicating with a drain trough 48 leading to any suitable point of discharge, preferably through the wall 43 of the building, whereby excess water dripping from any one of the four drip valves will be delivered through the opening ll of the trough 48 and discharged beyond the building wall.
The valve seat member l3 may be adjusted vertically in the coupling member ll by screwing its head l5 upwardly or downwardly in the threaded central bore 553 of the coupling member 11. A lock nut 5!! may be employed to prevent accidental changes in the adjustment, this lock nut having a central bore 52 in registry with the passage 26. Thus the pressure of the valve 23 upon its annular seat 21: may be nicely adjusted with reference to the pressure of the water in the main 4B, and this adjustment may be made at the factory where the valves are produced. This factory-predetermined adjustment will ordinarily be unknown to the user.
However, it will be desirable to allow the user to make a slight additional adjustment, and for this purpose I provide a resilient gasket 5 between the upper end of the body it and the lower end of the coupling member ll. By rotating the body It? upon its threaded connection with the coupling member ll, it may be moved upwardly or downwardly to regulate the drip during the night or at other times when the fowls do not have access to the valve. When the valve is properly adjusted the film of water will then tend to collect between the valve seat and the valve and form a seal which will prevent dripping except for a short period after a lateral displacement of the valvehas occurred.
The conical valve seat l4 allows the valve 25 to be tilted laterally as shown in Fig. l, the normal tilt under impact of a fowls bill being somewhat exaggerated in that view.
It will be observed that the valve 23 is in reality a double valve, the portion 24 serving as a check valve with its fiat annular face 2 3 seating against the lower end of the sleeve-like member 2| and the portion 25 serving as a needle valve to regulate the drip without moving to full closing position. But in fact, neither the annular face 24 or the needle '25 is ever fully closed, the notches 2i allowing water to escape to the dropcollecting knob whenever the film seal of the needle valve is broken by a tilting movement or by the pressure of the supply water.
Spring actuated needle valves which completely close are not sufficiently delicate in their operation to satisfy the requirements of a poultry waterer, and those which conform in taper to that of the seat are apt to stick and remain closed despite the effort of the fowls to open them. But I have discovered that by giving the needle a sharper taper than that of the seat and preventing it from closing farther than necessary to prevent a flow of water under very light pressure, such a valve may easily be vibrated laterally by the pick of a fowl, and when so vibrated it will allow the escape of at least one drop of water, and it can be easily restored to its normal position by a light spring with just sufficient tension to overcome the water pressure and prevent the escape of more than a few drops of water after each vibratory movement of the valve.
In Fig. 5 I have shown a modification in which a rubber sleeve or collar 60 protects the lower end of the spring 32a and covers the head 30a. The upper end of the spring 32a is in screw connection with the threaded outer surface of the sleeve-like body member 21a. and the protecting outer skirting 22a is separately formed and. screwed to the body at 6|. The drop of water is trapped by the convergent walls of the rubber collar 60, but is partially exposed and accessible to the fowls. Also the rubber presents a softer surface for them to pick at.
