Device for current collecting with separate contact shoes

Claim 2

A current collector adapted for movement along a longitudinally extending current supplying rail defining a dihedral contact surface, said collector comprising a frame member, at least one pair of contact shoes symmetrically arranged with respect to the bisecting plane of said dihedral contact surface and spaced apart substantially perpendicularly to said plane, each contact shoe having a single plane contact surface, the contact surfaces of said pair being adapted for sliding contact engagement with the plane of said dihedral contact surface, respectively, guide means on said frame member to guide said contact shoes of said pair towards and away from said rail substantially perpendicularly thereto, and a plurality of resilient contact shoe biasing means, one for each contact shoe, whereby each biasing means biases the corresponding contact shoe against said rail independently of the operation of the other biasing means.

Claim 3

A current collector according to claim 1, said guide means guiding said contact shoes parallelly to said bisecting plane.

Claim 4

A current collector according to claim 2, said planes of said dihedral contact surface having spaced apart confronting edges, said guide means comprising a partition wall extending in said bisecting plane and having a knife-shaped free end portion protruding between said edges.

Claim 5

An electrical distribution and current collecting assembly for use in high speed drive arrangements, comprising: a rail type stationary conductor having a pair of juxtaposed parallelly extending profile strips of conducting material, each having an outer and an opposed inner surface, the latter defining together a dihedral contact surface; at least one pair of contact shoes symmetrically arranged on either side of the bisecting plane of said dihedral contact surface, the contact surfaces of said shoes together forming a dihedral surface which conforms to the dihedral surface of said stationary conductor; a plurality of resilient contact shoe biasing means, one for each contact shoe, whereby each biasing means biases the corresponding contact shoe against the corresponding one of said pair of profile strips independently of the operation of the other biasing means; and guide means for guiding said contact shoes in a direction of movement towards and away from the dihedral surface of said stationary conductor and substantially parallel to the bisecting plane thereof.

Claim 6

An electrical distribution and current collecting assembly for use in high speed drive arrangements, comprising: a rail type stationary conductor having a pair of juxtaposed parallelly extending profile strips of conducting material, each having an outer and an opposed inner surface, the latter defining together a dihedral contact surface; at least one pair of contact shoes symmetrically arranged on either side of the bisecting plane of said dihedral contact surface, the contact surfaces of said shoes together forming a dihedral surface which conforms to the dihedral surface of said stationary conductor; a plurality of resilient contact shoe biasing means, one for each contact shoe, whereby each biasing means biases the corresponding contact shoe against the corresponding one of said pair of profile strips independently of the operation of the other biasing means; and guide means for guiding said contact shoes in a direction of movement towards and away from the dihedral surface of said stationary conductor and substantially parallel to the bisecting plane thereof.

Claim 7

An assembly according to claim 4, wherein said profile strips are spaced apart to define a longitudinally extending gap between the faces of the dihedral contact surfaces thereof, said guide means comprising a partition wall between said pair of contact shoes and extending through the gap between said profile strips for guiding the contact shoe assembly and limiting lateral movement thereof.
