Apparatus And Method For Extracting Energy From A Passing Train
US Patent:
6362534, Mar 26, 2002
Filed:
Aug 23, 2000
Appl. No.:
09/644730
Inventors:
William M. Kaufman - Swampscott MA 01907
International Classification:
H02P 904
US Classification:
290 1R
Abstract:
A system for extracting energy from the passing wheels of a railcar, converting the energy to into rotation of a shaft in first and second directions, converting the rotation of the shaft into electrical energy, and storing any excess generated electricity. A pivoting member includes a shaft, first and second arms extending from the shaft, and contact elements at the ends of the arms. The vertical reaction force imparted to the wheels of a passing railcar may be minimized by, among other techniques, orienting the pivoting member so that the contact elements move in a horizontal plane and by coupling the contact elements to the ends of the pivoting member arms via respective journal bearings.
