This invention relates to an apparatus for and parallel with the rail-sections. .The lugs mining coal, an object being to provide and rail sections are connectedby pins or means whereby thin seams of coal heretofore rivets 20 which bridge the space between left unmined due to the cost of mining, may these lugs and rail sections. 1

Having described the invention what is claimed is:

1. A sectional track of angular cross sec'-' tion rails, spacing bars havin their opposite ends removably enga ed t erewith, lugs spaced from and para-l el with the rail sections at opposite ends thereof, pins connecting the lugs and rail sections, and means removably positioned over the lugs of the ends of adjacent track sections and engaging the pins to detachably connect the sections.

2. A sectional track of angular cross section rails, spacin bars having their opposite ends removab ly engaged therewith, lugs spaced from and parallel with the rail sections at opposite ends thereof, pins connecting the In and rail sections, transversely U-shaped ars removably positioned over the ends of adjacent track sections and having slots to receive the pins to detachably connect the track sections.

In testimony whereof I aflix my signature.
