Abstract
Abstract An egg transferring or collecting device for collecting eggs from several superimposed channels and conveying them to a single channel comprises a main vertical endless chain conveyor with a number of baskets in the form of multi-tine forks, the baskets being pivoted so as to occupy either a ''''collect'''' position or a ''''deliver'''' position, both positions being stable. On the ''''up'''' moving side of the chain each basket is tipped to a collect position at a respective channel, and whether eggs are collected there or not, thereafter tipped to a deliver position. From this position eggs are collected at a collecting station during the downward movement of the chain and transferred to a belt conveyor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
266 words
A device for transferring eggs or like small fragile objects, said device comprising an endless conveyor chain which circulates in a vertical plane, a plurality of conveyor elements with parallel rake teeth pivoted on said conveyor, a plurality of superimposed stationary delivery stations with bottoms also formed of rake teeth parallel to said conveyor element teeth and pointing toward said conveyor, said conveyor elements passing through said delivery stations during a rising movement of said chain, a receiving station including rake teeth extending parallel towards said conveyor chain, said conveyor element teeth passing through said receiving station teeth during the chain descending movement wherein said conveyor elements are conveyor baskets, each of which has a receiving compartment and a delivery compartment, said compartments being inclined towards each other approximately at right angles, open at the top and formed by said teeth, said conveyor baskets being each suspended from said conveyor chain to pivot between stops about a horizontal axis extending perpendicularly to the plane of circulation of said chain, said pivoting movement being between a receiving position in which said receiving compartment extends approximately horizontally outwardly from said chain and said delivery compartment extends approximately vertically upwardly, and a delivery position in which said receiving compartment extends approximately vertically upwardly and said delivery compartment approximately horizontally outwardly, and changeover cranks associated with said delivery stations to pivot selected conveyor baskets forwardly into their receiving positions, before a respective delivery station is reached, stops to pivot said baskets back into their delivery positions after passing through said respective delivery station and before reaching the next delivery station.
Claim 2
Independent Claim
266 words
A device for transferring eggs or like small fragile objects, said device comprising an endless conveyor chain which circulates in a vertical plane, a plurality of conveyor elements with parallel rake teeth pivoted on said conveyor, a plurality of superimposed stationary delivery stations with bottoms also formed of rake teeth parallel to said conveyor element teeth and pointing toward said conveyor, said conveyor elements passing through said delivery stations during a rising movement of said chain, a receiving station including rake teeth extending parallel towards said conveyor chain, said conveyor element teeth passing through said receiving station teeth during the chain descending movement wherein said conveyor elements are conveyor baskets, each of which has a receiving compartment and a delivery compartment, said compartments being inclined towards each other approximately at right angles, open at the top and formed by said teeth, said conveyor baskets being each suspended from said conveyor chain to pivot between stops about a horizontal axis extending perpendicularly to the plane of circulation of said chain, said pivoting movement being between a receiving position in which said receiving compartment extends approximately horizontally outwardly from said chain and said delivery compartment extends approximately vertically upwardly, and a delivery position in which said receiving compartment extends approximately vertically upwardly and said delivery compartment approximately horizontally outwardly, and changeover cranks associated with said delivery stations to pivot selected conveyor baskets forwardly into their receiving positions, before a respective delivery station is reached, stops to pivot said baskets back into their delivery positions after passing through said respective delivery station and before reaching the next delivery station.
Claim 3
Dependent Claim
48 words
A device as recited in claim 1, wherein said cranks are each associated with a respective delivery station, means for driving said cranks synchronously with said conveyor chain to move into an operative position effecting said forward pivoting of selected conveyor baskets associated with the respective delivery station.
Claim 4
Dependent Claim
42 words
A device as recited in claim 2, wherein said cranks are driven by a drive derived from said conveyor chain, said stops being stationary elements, and adjusting arms secured each to said conveyor basket and acted upon by said cranks and stops.
Claim 5
Dependent Claim
60 words
A device as recited in claim 1, wherein an empty conveyor basket is held by its centre of gravity in its receiving position, said receiving compartment forming, in said receiving position, an inclined plane sloping towards said delivery compartment, said basket when loaded being urged into a delivery position by a change in the position of said centre of gravity.
Claim 6
Dependent Claim
105 words
A device as recited in claim 3, wherein each conveyor basket comprises a U-shaped carrier stirrup having free outwardly angled ends engaged in opposed members of a double conveyor chain so as to allow said basket to swing about an axis coaxial with said angled ends, and a tube slipped on the horizontal freely swinging straight cross-piece of said carrying stirrup, to which tube said rake teeth and said adjusting arms are secured, the tube projecting at least on one side beyond the ends of said carrier stirrup, to define a gap, and stops engaging in said gap to limit the rotation of said tube.
Claim 7
Dependent Claim
38 words
A device as recited in claim 5, wherein the links of said conveyor chain define circular openings therearound, said carrier stirrup being bent from wire having a circular cross-section so as to be freely rotatable in said openings.
