Description: |
| The inventor's first name is "Eleazer" in this patent; his other patents all use "Eleazar" and we have normalized the spelling to "Eleazar"."My invention consists in forming between the rails of a railway-track an underground tunnel having in the inside a series of pulleys and near the level of the ground a longitudinal slot... in order that a traction-rope may be used for drawing the cars along the track without impeding the passage of ordinary vehicles across the same." |
