Wrought iron or cast steel bar and hook, slotted and drilled at nose for link and pin when these are necessary.

Mr. Jamks McNabb, of Widder, Ontario, is the Ij^vkxtou and Okkjinal Patkntek of this Horizontal Latch Coupler, having obtained a patent for his device in Canada, October 12, 18,57; and during the ])ast year he obtained Letters Patent for the same in the United States. The "Miller" Coi'pler, being identical in principle, is held by Mr. McNabr to BE an infringement UPON THIS PATENT, AND IT IS NOW BEING ACKNOWLEDGED AS SUCH BY En(}Ineers and Mkchanical men, both IN Canada and the United States.
