The gates at the side of the track, as before 60 This invention relates to improvements in explained, are similar to the gate between the railway'gates, and has more particular relatracks, with the one exception that only one tion to gates intended as cattle-guards. of the pendent arms on the platform is used,

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In a railway-gate, the combination with a pivoted platform having a pendent arm, of a pivoted gate, a pivoted bell-crank lever connected to the pendent arm, a link connecting said gate and said bell-crank lever, whereby any pressure upon the platform will raise said gate into operative position, and a Weight connected to said bell-crank lever for returning the gate to its normal position, substantially as described.

2. In a railway-gate, the combination with a transverse shaft, of a platform pivotally mounted thereon,'a gate also pivotally mounted on said shaft, a pivoted bell-crank lever, and means for connecting said bell-crank lever to the pivoted gate and the pivoted platform, whereby upon the depression of the latter the former is raised into operative position, substantially as described.

3. In a railway-gate, the combination With i a transverse shaft, of a platform pivotally mounted thereon and provided with pendent arms, a gate also pivotally mounted upon said shaft, pivoted bell-crank levers connecting said gate and said pendent armsrespectively, and Weights also connected to said bell-crank levers, substantially as described.

4:. In a railway-gate, the combination with a transverse shaft, of a platform pivoted on the same and provided with pendent arms, a gate also pivoted on said shaft, pivoted bellcrank levers connected to said pendent arms, pivoted links connecting said bell-crank levers and said gate, and a Weight attached to said bell-crank levers, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

ALMOND HOWARD.
