Abstract
Abstract A conveyor, in particular for eggs, comprising two lateral chains of the type having closed annular links extending in perpendicular planes. The chains are interconnected by a number of transverse bars forming the actual carrier surface. Successive bars have different levels upon a common reference plane, so that at least the upper surface of each second bar is on a higher level than the upper surface of the first bar. One advantage is that eggs resting on two bars can be transported over steeper rises without rolling backwards.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
84 words
A conveyor, in particular for eggs, comprising a conveyor belt composed of bars of spring steel or like material, which bars extend transversely to the conveyor belt and have their end portions secured to chains of the type having closed annular links extending in perpendicular planes, which links, for traversing bends, permit temporary shortening of the chain by sliding one into to the other, characterized in that the successive bars in the belt are disposed at different levels relative to the plane of transportation.
Claim 2
Dependent Claim
84 words
A conveyor, in particular for eggs, comprising a conveyor belt composed of bars of spring steel or like material, which bars extend transversely to the conveyor belt and have their end portions secured to chains of the type having closed annular links extending in perpendicular planes, which links, for traversing bends, permit temporary shortening of the chain by sliding one into to the other, characterized in that the successive bars in the belt are disposed at different levels relative to the plane of transportation.
Claim 3
Dependent Claim
31 words
A conveyor as claimed in claim 1, wherein the difference in level between successive bars is obtained by an effective choice of the attachment of a bar to the chain links.
Claim 4
Dependent Claim
32 words
A conveyor as claimed in claim 1, wherein the bar ends are secured, for example by welding, to the tops of the vertical links and to the sides of the horizontal links.
Claim 5
Dependent Claim
28 words
A conveyor as claimed in claim 1, wherein the bar ends are secured to the side of the vertical links and to the top of the horizontal links.
Claim 6
Dependent Claim
26 words
A conveyor as claimed in claim 1, wherein the chains run in a guiding chute, and further comprising driven sprockets arranged for engagement with the chains.
