Abstract
Abstract A transfer station comprising a ram operable to push an article from a first conveyor to a second conveyor which is parallel to the first one at least in the station. A partition is disposed between the conveyors and is mounted for vertical sliding movement in response to movement of the ram, and for pivotal movement about a substantially horizontal axis. An assembly is selectively operable to lock the partition in its vertical position.

Claim 1
Independent Claim
158 words
A transfer station for moving an article from a first conveyor to a second conveyor parallel thereto at least in the station, said station comprising a ram operable to push an article from said first conveyor to said second conveyor, a partition between said conveyors mounted for vertical sliding movement in response to movement of the ram and for pivotal movement about a substantially horizontal axis, and means selectively operable to lock the partition in a substantially vertical position, said partition being mounted on at least one support slidable along a vertical guide, and being pivoted to said support for movement about a horizontal axis, said locking means including at least one rotary jack comprising a sectorshaped working chamber, a vane in said chamber mounted for rotation with said partition about an axis at the geometrical center of said sector, a fluid inlet on one side of said vane, and a fluid outlet on the opposite side thereof.
Claim 2

A transfer station for moving an article from a first conveyor to a second conveyor parallel thereto at least in the station, said station comprising a ram operable to push an article from said first conveyor to said second conveyor, a partition between said conveyors mounted for vertical sliding movement in response to movement of the ram and for pivotal movement about a substantially horizontal axis, and means selectively operable to lock the partition in a substantially vertical position, said partition being mounted on at least one support slidable along a vertical guide, and being pivoted to said support for movement about a horizontal axis, said locking means including at least one rotary jack comprising a sectorshaped working chamber, a vane in said chamber mounted for rotation with said partition about an axis at the geometrical center of said sector, a fluid inlet on one side of said vane, and a fluid outlet on the opposite side thereof.
Claim 3
Dependent Claim
56 words
A transfer station as claimed in claim 1, wherein said jacks are two in number, the partition is hung from a rod providing an axle supported for rotation in each of two spaced supports, and each support carries a respective rotary jack whose vane is rigidly connected to the rod for rotation about the axis thereof.
Claim 4
Dependent Claim
37 words
A transfer station as claimed in claim 2, wherein: said ram and said jack are pneumatically operated from a common source arranged such that said jack is under pressure when said ram is not, and vice versa.
