Description

-.|. F'. ANDREWS.
lmprovemerit in Railway-Signals.
"Pamnted April 23, 1872.
UNITED STATES PATENT JOSEPH F. ANDREWS, OF NASHUA, NEW HAMPSHIRE.
IMPROVEMENT IN RAILWAY SIGNALS.
Specification forming part of Letters Patent N 0. 125,925, dated April 23, 1872.
v Specification describing a new and Improved Railroad Signal, invented by JOSEPH F. AN- DREWS, of Nashua, in the county of Hillsborough and State of New Hampshire.
Figure 1 represents a longitudinal vertical section of my invention. Fig. 2 is atop view of the same.
Similar letters of reference indicate corresponding parts. a This invention has for its object to provide a practical means of operating signals at raiL road crossings by the trains that approach such crossings, and at a suitable safe distance therefrom, so as to give timely warning to persons approaching the track when the trains are crossing. The invention consists in the arrangement of a "ertically-movable rail set on springs, which is crowded down by the weight of the train passing over it.
A in the drawing represents the railroad track. B is the signal-stand erected at the place of a crossing. O is the rail, by the action of which the signal is to be set. This rail is supported by rubber springs a a, which rest on a firm bed, b. When the train passes over the rail (1 it depresses the same, and causes it to compress the springs a. This downward motion is utilized in swinging a pivot-ed bellcrank, d, which is, by a rod, 6, connected with the rail 0, and, by a system of other rods and levers, f f j, with the signal D. The latter is thus moved for display whenever the train passes over the rail 0. Immediately after the train has left it, the rail (3 is righted by the FFICE.
