The invention relates to a nipple drinker formed by; a) the body of the nipple (1) which has multiple sections including an upper section formed by a dome (9) having a central circular groove (10), three hollow cylindrical sections (11) of different diameters, which are stepped one under another, and a lower frusto-conical section (12), the inner surface of which is provided with a small circular flange (13); a tubular pin (2) having a lower solid cylindrical portion (14); c) two spheres (3 and 6); d) two maximum-precision washers (4 and 7); e) a hollow, cylindrical inner seal holder (5), the upper outer portion of which is provided with a washer (15), leaving a space between the two portions of 0.3 mm, in which the washer (4) is housed; and f) a cylindrical outer seal holder (8), the lower portion of which is provided with a small frusta-conical section (16) that is inclined slightly by 17° towards the center.

TECHNICAL FIELD

The present patent application refers to a Nipple-Type Poultry drinker consisting in a device useful to deliver water to poultry when they activate the sphere protruding from the bottom part of the nipple, at the moment of drinking water.

BACKGROUND OF THE INVENTION

Different types of drinker are known in commerce, such as open system and close system. The open system, in which the water is directly in front of the poultry eyes, consist in a metallic container or plastic container when dealing with manual drinkers, having the mouth in an inverted position and on which there is a dish which delivers water in a dosing manner, when the poultry place their beak in the dish; with the disadvantage that the poultry soils the water with food, or frequently they return the drunk water into the dish thus contaminating the same. This type of drinker is referred to as bell type, channel type, can type etc.

There also are open type automatic drinkers in general bell type which receive the water directly from a water tank and deliver the water to poultry when ever needed. As it is an open system it is necessary to wash all at least once every day with the consequent problem of having personnel in and out constantly which besides molesting the poultry this can be a vehicle for poultry diseases.

The nipples correspond to the closed system and due to its design, the water in it cannot be soiled by the birds. The water that the poultry drink is that which the farmer gives them, which must be of excellent quality.

ADVANTAGES OF THE INVENTION

The nipple drinker subject matter of the present patent application has the following advantages: It is the only nipple-type drinker not having an outer pin activator. All other nipples have an outer pin which is activated by the peak of the birds but besides that in an involuntary manner with their comb, head, wings, thus producing more humidity in the poulterer's bed. This drinker carries two seals and two spheres made of high precision Stainless steel securing a dry bed. Using the same water column it delivers more water to poultry that any other nipple does, with no waste and no humidity. It requires less water column height and delivers a greater flow, which means there is no spilling when there is greater pressure, thus maintaining a dry floor.

DESCRIPTION OF THE INVENTION

The Nipple Drinker, subject matter of the present patent application, as shown inFIGS. 1 and 2, comprises: a) a Nipple body (1); b) a pin (2); c) a sphere (3); d) a maximum-precision washer (4); e) an inner seal holder (5); e) a sphere (6); f) a maximum-precision washer (7); g) an outer seal holder (8).

The Nipple Body (1), as seen inFIG. 3, is comprised by various sections such as: a top section, formed by a semi-sphere (9) having a diameter of 7.45 mm, having a circular slot (10) at its center having a diameter of 3.15 mm; three hollow cylinder shaped sections (11) having different diameters, located each under the other in a staggered manner; and a lower frusto-conical section (12) with a top outer diameter of 12.35 mm and a bottom outer diameter of 16.70 mm, having a small circular flange (13) at a height of 6.23 mm, seeFIG. 4. The nipple body (1) is made out of poly-acetal co-polymer, having a weight of 3 g and a height of 33 mm.

Pin (2) has a tubular shape with a lower cylinder part (14), it is solid and made of poly-acetal, having a weight of 0.18 g.

The spheres (3) and (5) bear a diameter of 0.635 cm and are made of stainless steel.

The maximum-precision washers (4) and (7) are made of stainless steel and have a outer diameter of 0.95 cm, an inner diameter of 0.57 cm, a thickness of 0.03 mm and a weight of 0.25 g.

The inner seal holder (5) has a hollow cylinder shape with a washer (15) located at the top outer part, such as shown inFIG. 5, with a 0.3 mm gap between the two parts, wherein the washer (4) fits in, and it is made of neoprene having a weight of 0.22 g.

The outer seal holder (8) has a cylinder shape having an outer diameter of 12.35 mm, as shown inFIG. 6, a thickness of 3.1 mm, bears in the bottom part a small frusto-conical section (16) having a height of 1.8 mm, a slight inclination towards the center of 17.43° determining an inner diameter of 7.45 mm and an outer diameter of 7.75 mm; it is made in poly-acetal co-polymer, which is a very strong material that will resist the continuous picking of the birds when activating the inner sphere (6), having a weight of 0.4 g.

The nipple drinker design allows a direct engaging to the tubing, in general PVC tubing of 1.27 cm or 1.9 cm which maintains available water for the birds.

Both the inner (5) and outer (8) seal holders, and both spheres (3) and (6) act in an independent manner, producing a double seal which stay closed thus preventing the water to flow while not activated by the birds.

When the bird acts on the stainless sphere (6) of the bottom part of the nipple with its peak, the movement of said sphere (6) immediately activates the second sphere located on the inner seal holder (5) in an independent manner and at the same time allows the water to flow which is now received by the birds.

The water flow passing by the nipple is regulated by the pin (2) located in the inner and top part of the same.

FIG. 3is the perspective view of the nipple body and shows the nipple body (1), the top section, formed by a semi-sphere (9), the cylinder shaped sections (11) and the lower frusto-conical section (12).

FIG. 4shows the view of the bottom part of the nipple drinker comprised by: the nipple body (1), the sphere (6), the maximum-precision washer (7), the outer seal holder (8), the top section, formed by the semi-sphere (9), the cylinder shaped sections (11) and the lower frusto-conical section (12).

FIG. 5shows the perspective view of the inner seal holder wherein one can see the shape of the inner seal holder (5) and the washer (15).

FIG. 6shows the perspective view of the outer seal holder wherein it is shown the outer seal holder (8) with the small frusto-conical section (16).
