Abstract A current collector to be engaged with a conductor rail and specifically to desired conductors thereof, which collector comprises a box-like frame of an insulating material, in which at least three contact fingers are movably arranged so that at least two of said fingers may be brought simultaneously from a retracted position inside the frame to a position protruding from the frame to engage the conductors in the conductor rail, said fingers being operated by a camshaft member slidable in its axial direction and turnable around its axis and provided with cams to engage the fingers, the cams being so positioned that, at turning of the camshaft member, a desired pair of contact fingers, depending on the axial position of the camshaft member, is brought into contact with the corresponding conductors of the conductor rail. Preferably, the collector frame further comprises a turning lever connected to and allowing axial movement of the camshaft member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
A current collector for a conductor rail of the type having a plurality of separate longitudinally extending conductors, which current collector comprises a frame; at least three electrical contact fingers each supported on said frame for movement relative thereto between a retracted position out of engagement with a corresponding conductor of said rail, and a protruding position of engagement with said corresponding conductor; a camshaft member supported on said frame for axially slidable and rotary movement relative thereto; and cams on said camshaft member positioned to selectively engage respective contact fingers according to the axial position of the camshaft member and to move such contact fingers from their respective retracted positions to their respective protruding positions to engage corresponding conductors of said rail.
Claim 2
Dependent Claim
123 words
A current collector for a conductor rail of the type having a plurality of separate longitudinally extending conductors, which current collector comprises a frame; at least three electrical contact fingers each supported on said frame for movement relative thereto between a retracted position out of engagement with a corresponding conductor of said rail, and a protruding position of engagement with said corresponding conductor; a camshaft member supported on said frame for axially slidable and rotary movement relative thereto; and cams on said camshaft member positioned to selectively engage respective contact fingers according to the axial position of the camshaft member and to move such contact fingers from their respective retracted positions to their respective protruding positions to engage corresponding conductors of said rail.
Claim 3
Dependent Claim
34 words
A current collector according to claim 1 including a lever connected to said camshaft member to rotate same, said lever being disposed to allow axial movement of the camshaft member relative to the frame.
Claim 4
Dependent Claim
55 words
A current collector according to claim 1 including notches in said camshaft member spaced apart from one another in the axial direction of the camshaft member, and a resilient member supported by said frame and positioned to engage said notches, one at a time, to retain the camshaft member in a corresponding selected axial position.
Claim 5
Dependent Claim
23 words
A current collector acccording to claim 1 including a prong on said camshaft member and extending therefrom to facilitate the axial movement thereof.
Claim 6
Dependent Claim
41 words
A current collector according to claim 4 wherein said prong is carried on the camshaft member so that when same is rotated to move said contact fingers in their protruding positions, the prong is in a concealed position within the frame.
