RAILWAY-GATE.

SPECIFICATION forming part of Letters Patent No. 795,022, dated July 18, 1905,

Application filed April 4, 1905. Serial No. 253,826.

To all whom, it may concern.-

Be it known that I, AUGUSTA BERG, a citizen of the United States, residing at Lanse, in the county of Clearfield and State of Pennsylvania,-have invented certain new and useful Improvements in Railway-Gates, of which the following is a specification.

This invention relates to improvements in automatic railway-gates, and has for its ob ject to produce a device of the character mentioned which will be both simple in construction and efficient in operation.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a perspective view showing the device applied to a railroad-crossing. Fig. 2 is a transverse sectional view. Fig. 3 is a horizontal sectional View taken through the mechanism on one side of the track.

Corresponding and-like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The numeral 1 indicates the track-rails, and 2 is a highway crossing the track. Posts 3 are located at both sides of the highway on each side of the track and gatesl of any suitable construction are hinged to these posts. Pinions 6 are attached to the lower part of the gates by means of metal heel-plates or sockets 7 and are so placed that their center points coincide with the lines through the hinge-pivots. When necessary, a portion of the gate-post may be cut away to allow the pinions 6 to operate freely. Racks 8, mesh ing with pinions 6, are carried by rods 9, which pass through openings 10 in the web of the rails and guide members 11 on the posts 3.

The inner ends of these rods 9 on each side of the track are joined by bars 12, the ends of which extend along the track in both directions and are connected to heads 13, which slide in slots 14 in the rails. These bars 12 are made of spring metal and act to hold the gates normally across the track, so that there is a clear passage for traflic on the highway.

The operation of the device is as follows: Normally the gates are swung across the track, as shown in Fig. 1; but when a train approaches the flanges of the wheels will engage the bars 12 and press them in toward the rails on each side. This is made possible by the fact that the ends of the said bars are attached to the sliding heads 13. The rods 9 being connected to the bar 12 are also pushed in, and the racks 8 cause the pinions 6 to turn and swing the gates across the road. When the train has passed, the spring-bars 11 will cause the gates to swing back across the track. It will thus be understood that this railwaygate as constructed by me automatically performs the double function of keeping traffic off the track when a train is passing and of keeping stray animals, &c., from wandering along the track when the highway is open.

What I claim as new, and desire to secure by Letters Patent, is

1. In an automatic railway-gate, the combination of posts on both sides of the road and each side of the track, gates pivoted to said posts and provided with pinions for operating same, racks engaging said pinions and carried a by rods passed through openings in the rail, and spring-bars connecting the ends of said rods on each side of the track and having their ends bent toward the rails and slidably connected thereto.

2. In an automatic railway-gate, the combination of posts at both sides of the road and each side of the track, gates pivoted to said posts and provided with pinions for operating same, racks engaging said pinions and carried by rods passing through openings in the rail, and spring-rods having their middle portions arranged parallel with the tracks and connected to the said rods, and having their end portions inclined toward the proximal rails and fitted in longitudinal slots thereof.

3. In an automatic railway-gate, the combination of posts on both sides of the road and each side'of the track, gates pivoted to said posts and provided with pinions for operating same, racks engaging said pinions and carried by rods passing through openings in the rail, and spring-bars connecting the ends of said rods on each side of the track, the ends of which are bent in toward the rails and connected to heads sliding in slots in the rails.

In testimony whereof I aflix my signature in presence of two witnesses.
