IMPROVEMENT IN RAILROAD-SIGNALS.
Specification forming` part of Let ers Patent No. 48.085, dated June 6, 1865.
, at right angles to the track and having an upwardly -projecting flange which is suddenly depressed by the lia-nge of the wheel which runs over it so as to vibrate the lever, and by means of a connecting-Wire oscillate a rock-shaft and draw upon a lWire Which is stretched from pole to pole alongside of the railroad and connected to bells at suitable intervals, to give notice to an approaching train or to passengers on railroad-crossings, or to communicate the alarm to a point in advance to which the Wires are conducted; in short, to herald the approach of the train to any required spot or distance, according to the arrangement and connection of the Wires.
`'lo enable others skilled in the art to which my invention appertaius to fully understand and make the same, I will proceed to describe its construction and operation.
A A are the railroad -rails, and Bis a truck. C C are the projections from the upper side of the lever D, which is pivoted at a point, E, so that the lia-nge of the passing Wheel Will depress it and draw upon the cord F, vibrating the rock-shaft G, which is mounted on the post K, and drawing upon the cord H, which rings the bell I and others connected to it. Suitable springs, J, cause the oscillating and continuous motion of the bell, and the lever D is raised to its normal position by a .spring beneath it.
A modification ofthe device is shown, Where a shaft, L, Wit-l1 a counterbalance-iveight, M, passes under the track, an arm or standard, N, attached to the shaft, being vibrated by the passing Wheel, causing the arm O to draw upon the cord P and pull the bell-Wire H.
I do not coniine myself to bells attached to the Wires, as I may elect to eiiect the alarm by other audible meanssuch as hammers or hornso'r to employ an electro-magnet in connection therewith, making the circuit by the depression of the said lever and conveying the intelligence desired.
Having thus fully, clearly, and exactly described the nature, construction, and operation of my invention, what I claim `as ner therein, and desire to secure by Letters Patent7 is The bar L, laid transversely to the track, and provided with an arm, N, and counterbalance- Weight M, for the purpose, and arranged substantially as described.
