Abstract
Abstract Conveyor having low-speed and high-speed zones, and a connection zone there between, comprising a series of load-carrying platforms slidable one against the next to effect acceleration in the connection zone, wherein each platform is provided with connectors for linking it to the two adjoining platforms in the connection zone, a drive mechanism for the connectors being provided to effect movement thereof relative to their respective platforms, whereby progressive sliding movement of each platform relative to the adjoining platforms in the connection zone is effected, of which the following is a specification.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
160 words
A conveyor for providing a continuously moving load-carrying surface and including a low speed zone, a high-speed zone and a connection zone between the low speed and high-speed zones, the conveyor comprising: a series of elongated conveyor elements; guide and support means for guiding and supporting said elements in side-by-side relationship in said low speed zone; guide means and support means for guiding and supporting said elements in said connection zone; drive means for moving said elements; a fixed connection member on each of said elements; a movable connection member on each of said elements, the movable connection member on one element connectable to the fixed connection member on the adjacent element; and drive means in said connection zone for cooperation with said movable connection member; said drive means being so constructed and arranged that each movable connection member is moved along an edge of the related conveyor element to effect relative sliding between adjacent elements in said connection zone.
Claim 2
Dependent Claim
160 words
A conveyor for providing a continuously moving load-carrying surface and including a low speed zone, a high-speed zone and a connection zone between the low speed and high-speed zones, the conveyor comprising: a series of elongated conveyor elements; guide and support means for guiding and supporting said elements in side-by-side relationship in said low speed zone; guide means and support means for guiding and supporting said elements in said connection zone; drive means for moving said elements; a fixed connection member on each of said elements; a movable connection member on each of said elements, the movable connection member on one element connectable to the fixed connection member on the adjacent element; and drive means in said connection zone for cooperation with said movable connection member; said drive means being so constructed and arranged that each movable connection member is moved along an edge of the related conveyor element to effect relative sliding between adjacent elements in said connection zone.
Claim 3
Dependent Claim
89 words
A conveyor as claimed in claim 1, wherein the fixed connection member is constituted by a pin mounted in each of the four corners of the platforms and movable axially by ramps, and wherein the movable connection member comprises a chain sliding in a groove formed in the periphery of each platform, a bayonet attachment on said chain and adapted to be connectable to one of said bolt pins of the preceding platform to connect said platform to the chain and to be driven by it during its sliding.
Claim 4
Dependent Claim
62 words
A conveyor as claimed in claim 2, wherein a roller is mounted on said chain, the displacement of which causes said drive means in said connection zone engaging with said roller to cause sliding of said chain in said groove, said roller attached to the chain at a distance from the bayonet attachment equal to half the length of the said chain.
Claim 5
Dependent Claim
93 words
The conveyor of claim 1 wherein the fixed connection members each comprise a bent dog, one such dog being fixed at the extremity of each of the small sides of the platform, each dog including a disc portion, and wherein the movable connection members comprise an endless screw, a screw arranged in each of the longitudinal sides of each platform and an endless disgonal screw connecting said endless screws by means of conical pinions, eacH of the endless screws including a cursor for engagement with the disc portion carried by the adjacent platform.
Claim 6
Dependent Claim
25 words
A conveyor as claimed in claim 4, including a roller mounted on the endless diagonal screw displacement of said roller rotating said endless diagonal screw.
Claim 7
Dependent Claim
81 words
A conveyor as claimed in claim 1, said movable connection member comprising a flexible member slidable in a recess formed in each of the two longitudinal sides of the platform and also formed along a diagonal of the platform, a roller being fixed to said flexible member, causing its sliding in the recess along the diagonal of the platform, and a slide connected to each extremity of the flexible member, said slides connectable to the fixed connection members, of adjacent platforms.
Claim 8
Dependent Claim
66 words
A conveyor as claimed in claim 1, wherein each movable connection member comprises a screw member extending along each of the longitudinal sides of a platform, and a toothed wheel on each end of each screw member, the toothed wheels engageable with said support and guidance means, a slide on each of said screw members, said slides engageable with the fixed connection member on adjacent platforms.
