Abstract
A device for receiving power from a rigid conductor extending in the direction of advance to an electrically driven, rail vehicle, which comprises current collecting members independently supported on a base through elastic members having a low spring constant, as far as possible, within the working ranges. The current collecting member has a higher predetermined vertical level than the average static height of the rigid conductor so as to be displaced back to the average static level of the rigid conductor. The current collecting member is maintained in a resilient condition during operation so that it is responsive to any sudden changes in pressure and thus prevent separation from the rigid conductor. Supporting members are independently supported on the same base through the elastic members and the supporting members have a vertical level which is equivalent to the average static height of the rigid conductor to be maintained during operation for resiliently supporting the rigid conductor which is partially displaced back.
