Description

The present invention has for its object a nest for egg-laying installation, more specially for egg-laying installation equipped with an automatic system for collecting the eggs, One aim of the invention is to provide a new/for egg-laying installation having altogether the advantages of being easy to manufacture, cheap and pratically everlasting, of being attractive for the hens so that the hens quickly get accustomed with the new nest, of being, due to its own cons-titution, able to remain clean for a long time and further of being easy to clean, and of allowing the hens to be given sanitary or even veterinary treatments without requiring any special work, without any inconvenience for the hens, and without any risk of spoiling the eggs.

According to the invention, a nest for egg-laying installation is constituted by a basket shaped body with a solid bottom, provided with a perforated double-bottom which is inclined towards a flush aperture in e side wall of the body, through ¾hich the laid eggs are to be evacuated towards any know system for collecting the eggs.

Advantageously, the perforated double-bottom is removable, and both pieces, i.e. body and double-bottom, are made of molded plastic material of the same colour, preferably yellow or the like.

Such a nest is obviously easy to manufacture and therefore cheap.

As the hens see the solid body bottom through the perforated double-totom, they do not hesitate to lay in the nest,, as it occurs in the egg-laying installations where the The attractiveness of the nest is still increased by the fact that the air confined under the hen betwean the body bottom and the perforated double bottom has a warmth insulating power completed by the own insulating power of the molded plastic material. Further, it has been proved by experience that the hens are more attracted by a yellow colouring, probably because it looks out approximatively as the straw. All these causes do that the hens get quickly accustomed with the nest according to the invention, even when they did previously nest and lay on straw nests.

- The excrements, eggs without shell broken when laid, and any other dirts brought by the hens in the nest, pass through the perforated double bottom, which can thus remain clean a long time, and fall into the solid . ■ body bottom, which only need to be cleaned from time to time. The collected eggs are consequently pratically never dirty.

Finally, one may pour within the nest, on the solid body bottom and under the perforated double-bottom, a disinfectant or insecticide liquid which evaporates as a result of the warmth generated by the hen and penetrates the plumage thereof, without inconvenience for the hen nor impaling the quality of the eggs. One can also pour a volatil liquid medicament, for instance for the treatment of the hen bronchi maladies.

Another aim of the invention is to provide a nest for egg-laying installation of the above type, with a perforated double-bottom the cleaning of which is automatically ensured merely by the movements of the hens laying in the nest · tuted by a grate with bars the tipper surface of which forms a continuous surfacei and the sross-section of which presents at all points a sharp acute angle adjacent to said continuous surface.

Due to this feature, the excrements or other dirts laid upon said continuous surface of the perforated double bottom fall directly into the solid bottom of the body when they are swept by the hen stiring in the nest, without adhering to the sides of the bars because they are cut by said sharp acute angle. It has been proved by experience that such a perforated double bottom remains clean for ever, and that, in the contrary, with a grate having for instance round cross-section bars, the spaces between the bars are soon obstructed by the dirts which dry and gather on the sides of the bars.

These and other advantages and objects of the present invention will be readily apparent to those skilled in the art from a consideration of the following description taken in connection with the appended drawings; Fig. 1 is a simplified cross- section of an egg-laying installation equipped with a nest according to the invention ; Pig. 2 is a plan view of the nest according to the invention ; Fig. 3 is a cross-section along the line III-III of fig. 2 ; Fig. 4 is a front view of the nest according to the invention, and Fig. 5 is an enlarged detail in cross-section of the perforated double-bottom of the nest according to the in each with a nest 3 fitted therein; The nest 3 is ,_ji^oj i to--te provided with a perforated double-bottom 6 whichJ,s,inclined through which aperture the laid eggs roll to fall upon a slo pe 8 and from there upon a collecting endless conveyor 9· The body 4 has an upper rectangular horizontal fledge the rear corners 10 of which are intended to rest on support 22 provided in the box 2, and the front part of which compri ses a raised horizontal portion 11 intended to rest on a front support 21 of the box 2, and a vertical portion 12 which forms an abutment against said front support 21 · The perforated double-bottom 6 is supported upon the solid bottom 5 of the body 4 by feet 13 relied by a reinforcement rib 14, and, upon a shoulder 16 of the body 4, by a peripherical rib 15.

The perforated double-bottom 6 is constituted as a grate with bars' 17, the cross-section of which is clearly shown by the fig. 5. The upper surface of the bars forms a continuous surface 18, and their cross-section presents at all points sharp acute angle 19 adjacent to said continuous surface 18.

While a particular embodiment of this invention has been illustrated and described herein, it is intended that this invention be not limited to such disclosure, and changes and modifications can be made and incorporated within the scope of the claims.
