Alexander Bass |

Abstract:
This invention relates to portable railways and it consists, among other things, in securing the rails and crosspieces or ties to each other by means of rivets whose bodies are square or angular, and which are placed in holes of like form made in the rails and cross- pieces, in such a manner that they cannot move upon each other, but are, by means of the form of the rivets, held rigidly to each other. My invention further consists in locking-pieces which project from the crosspieces at the ends of the sections, and interlock with each other by engaging merely by lateral contact.
Claim:
The combination, with the rails A A and crosspieces B of the sections of a portable railway, of square-sided rivets for securing the rails and crosspieces together. |
