DAVID C. BAUGHMAN, OF ALBION, INDIANA.

RAILROAD-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 249,873, dated November 22, 1881,

(No model.)

To all whom it may concern:

Be it known that I, DAVID C. BAUGHMAN, of Albion,in the countyof Noble, and in the State of Indiana, have invented certain new and useful Improvements in Railroad-Signals; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and

to the letters of reference marked thereon, making a part of this specification.

This invention relates to certain improy e ments in railroad signaling apparatus; and it has for its objects to provide a means whereby the proper signals may be displayed either during the day or night, and the signal-lantern employed for night-signals may be supplied with air from a suitable building and the products of combustion discharged therein, so as to render the lantern free from external drafts, as more fully hereinafter specified. These objects I attain by the apparatus and devices illustrated in the accompanying drawings, in which I Figure 1 represents a vertical sectional view of my apparatus; Fig. 2, an interior view of the wall of the building or room from which the device is operated, showing the operating mechanism; Fig. 3, a side elevation of my invention; and Fig. 4 is a detail view, showing the devices for actuating the signals U.

The letter A indicates the wall of a room, building, or other structure, from which extends, on the outside, a frame, B, constructed of metallic tubes, preferably on account of economy, of the ordinary iron gas-pipes. Between the upper and lower horizontal portions of the said frame is pivoted to suitable connections, 0 D, a lantern, E, which is rectangular in shape, and is provided with bulls-eyes G and H on its four sides, the bulls eyes G being colored or tinted and arranged opposite each other, the bulls-eyes H being of clear glass and arranged opposite each other.

The letter I indicates a horizontal hollow shaft extending through the section K of the lower portion of the frame B. The said shaft, at its outer end, is provided with a beveledgear wheel, L, which engages a beveled-toothed segment, M, on the bottom of thelantern, wh ereby the said lantern may be given a partial rotation. The inner end of the said shaft is provided with a pulley, N, from which extend the cords 0, having the white and colored balls I? at their ends, whereby the shaft may be partially rotated in either direction to display the bulls-eyes to the line of the track, as may be desired. The shaft I is hollow, and through it passes a rod, R, the outer end of which is provided with a curved slot, which engages a pin, S, on a rock-shaft, S,journaled in the lower part of the lantern. The said shaft I, at its inner end, is provided with a lever, T, by means of which it may be reciprocatcd back and forth. The rock-shaft S, at its ends, carries the signals U, which are located at the sides of the lantern having the tinted bulls-eyes in such manner that they may be shifted simultaneously by reciprocatingthe rod R, in order to signal in both directions along the track. The curved slot in the end of the rod 1% permits the quarter-revolution of the lamp without affecting the vibrations of the signals U.

The lantern at the top and bottom communicates with the hollow frame B, the ends of which communicate with the interior of the building or compartmentin such manner that the air necessary to support combustion may be drawn directly from such building or compartment and the products of combustion. discharged therein to protect the lamp from violent drafts in windy or stormy weather.

The cap V (shown in Figs. 1 and 8) prevents the products of combustion from escaping directly into the open air through the coupling above the lantern.

I may use a swivel perforated cap, and a vane attached to it, instead of a closed cap; but this feature will form the subject of another application for a patent.

The letter W indicates a detent having three notches, w, by means of which the lever T may be locked in three different positions. When the tinted sides of the lantern are presented to the line of the track and the lever is held in the central notch the movable signals will occupy similar relative positions on opposite sides of thelantern, which will indicate that all trains on both sides ofthe signal must be stopped. When the lever is shifted to either of the side notches the signals will occupy dissimilar positions on opposite sides of the lantern, indicating that the train must switch off on one side and that the train on the opposite side has the right to the track. When it is desired to indicate that the track is clear the attendant draws on the white ball, so as to partially rotate the lantern and present the white sides and plain bulls-eyes to the line of the track.

What I claim, and desire to secure by Lettors Patent, is

1. In combination with the rotating lantern, the tubular frame communicating therewith and with a suitable apartment or structure, whereby sudden drafts are prevented from entering the lantern, substantially as specified.

2. The combination, with the frame 13, the lantern pivoted thereto, and the horizontal tubular section K, of the hollow shaft I, arranged in section K, and provided with bevel-gear L, the segmental rack on the lantern, the pulley N, and the cords thereof, provided with balls with a curved slot, which engages a pin, S, on

said shaft, a lever, 'I, on the outer end of rod R, and a notched detent, W, fixed to the wall A, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 7th day of J uly, 1881.

D. O. BAUGHMAN.
