To all whom it may concern: ing two or more grooves in its periphery, Beitknown that we, TIMOTHY H.

Having described our invention, what we claim, and desire to secure by Letters Patent,

1. A gate for a railroad-crossing, comprislng posts having pulleys near their tops, a. drum mounted on one of them and means for rotating it, pairs of oppositely-extending arms pivoted to each of said posts, a chain or flexible connection having several chains connecting thereto, one end of the main chain being secured to the drum and adapted to be wound upon it, the opposite ends of the chains passing over pulleys and secured to the ends the arms over or around the upper portion or the post and a walking-beam pivoted to said post having its ends connected to the arms for the purpose of operating said arms simultaneously.

3. A gate for a railroad-crossing comprising posts, a drum mounted on one of them and means for rotating it, pairs of arms pivoted to said posts, antifriction-rollers at the upper ends of said posts, a flexible connection between said drum and the end of one of the main arms over said roller, a walkingbeam pivoted to each post and connecting the arms of its pair for the purpose of oper ating them simultaneously, and auxiliary chains connecting the aforesaid chain with the remaining posts for the purpose of operating the arms.

In Witness whereof we have hereunto set our hands on this th day of June, 1895.
