IMPROVEMENT IN RAILROAD-SIGNALS.

Specification forming part of Letters Patent No. 1 77,561, dated May 16, 1876; application filed April 24, 1876. i

To all whom it may concern: V

Be it known that I, IRA ROBBINS, of Hughesville, in the county of Lycoming and State of Pennsylvania, have invented a new and Improved Slide-Signal for Railroads; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, in which- I Figure 1 is'a side elevation of my invention applied to a railway-track, showing it, free from obstruction. Fig. 2 is a front elevation of the device on the right-hand side of the railway-track, signaling danger; Fig. 3, a similar view on the left-hand side of the railwaytrack, in the position shown in Fig. 1.

The invention consists in erecting, along mountain or hillsides, where there is danger of slides of earth, rocks, or stones, aseries of posts, between which suitable panels are hinged, either above or below, as the 'case may require, so as to connect with signals near the track. These panels may be extended any distance required along a mountain where there is danger of slides, afterwhich a single small wire is extendedboth ways tothe signal.

The latter is not made visible to the engineer of a train of cars unless a slide has occurred, when the wires are pulled V by the force of the slide striking any one of panels or sections, and the signalis raised. The engineer thus has time to stop the train before running into the slide. These panels may be from sixteen to twenty .feet long, and from two to ten feet high, according to-the nature of the situation-where they are to be put up.

A represents a railroad-track, which is encompassed on both or either side by a mountain, hill, oracclivity. B is a series of posts,

placed at a suitable distance apart, and each pendicular attitude with the broad side facing the direction of the track. By carrying the signal-plate Gr backward into a horizontal plane, the catch-shoulder obtains a bearing upon it, so that it is retained in that position. The lower lever-arm c is connected with that of another lever 01" levers by a cord, E and thence with another spring-catch, so that a slide striking any of the panels will have the effect of raising the signal in time to warn an approaching train of its danger.

I claim as new is- 1 The combination of bottom-hinged panel D, levers (l, and spring-catches F with signals Gr, connected by cords or wires, substantially as shown and described, for the purpose specifled.
