Be it known that I, IVAN ILLINE, engineer, a subject of the Emperor of Russia, residing at Kharkov, in the Province of Oharkow, Russia, have invented certain new and useful Improvements in Apparatus for Railway Fog Signaling; and I do hereby declare the following to be a full, clear; and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The ordinary visible signals which regulate the approach and departure of trains at railway-stations are not reliable in dull fogg weather, as either they are entirely invisible to the engine-driver on the train or else can only be seen from such a short distance that a stoppage within the prescribed limits is not possible. In such cases so-called fog-signals are used, which consist of explosive matter inclosed in capsules fastened on the rails. The capsule explodes by means of the pressure of the wheels going over it and by its sharp report rouses the attention of the train officials. These fog-signals require special officials, who walk along the track and secure the capsules on the rails by hand. There are,-however, considerable objections to this plan. At small stations the proper person may not be momentarily available, while at large stations with a great deal of traffic there is much risk to the workmen in simple manner by placing angle-levers at a suitable distance from the station to an arm of which one or more fog-signals are fixed.

illustrates the apparatus in plan View, and Figs. 2 to 4 illustrate single parts thereof.

Near the railway track an angle-lever b is arranged in a box a. In Fig. 1 two such le' vers are illustrated, one behind the other, which are connected by means of a movable rod 0. One arm of the lever 12 engages with a bar d, which is suitably guided and has at its other end a widened extension d, on'which can be placed a thin metal casing containing the fog-signals. shown.) The fog-signals may of course be applied to the bar in other suitable ways.

, The levers b are preferably fixed on the sleep- The bars d are coners, as shown in Fig. 1. neoted, by means of the rod 0, with onearm of the angle-lever e, movable in the perpen= dicular direction in a bearing, the free end of which angle-lever bears a heavy weight. on the same arm of the angle-lever e adraw-wire f is secured, which wire extends to the rail way-station and is there fastened to a handlever. The leverb, like the lever e, is usuallyin the position indicated by-dotted lines. If the fog-signals are to be laid down, then the hand-lever at the station is shifted, and this by means of the wire f, causes the anglelever e to be set free,the weighted arm of which is sufficiently heavy to bring the lever into the position indicated by the dotted lines. In this position the widened ends d of the bar (1 rest on the rail, which at this point can and the weight of the weighted arm of the angle-lever draws back the rod 0, so that the bar (I moves away from the rails.

, Devices of this kind suffer from the great drawback that there is a possibility that the wheels of the passing train will push the lever cl, with its detonating signals, from the rail, so that the fog-signals remain inactive. To avoid this, a flat cross-piece d is arranged at the lower side of the enlargement d, Figs. 1 and 2. When the rod d is advanced, this cross-piece d presses with its straight front side firmly against the counter-rail, and thus prevents a lateral displacement of the rod d,

(Four in the construction as the red when pushed at its end to move would have to describe a sector-like course. The flat cross-piece d having a long bearing on the rail, will prevent this movement, so that a train passing over the track must explode the detonating signals under all circumstances.

It is preferable to connect the present apparatus with a visible signal with the object of sparing the fog-signal Whenever the former can be seen. The best is the simple signal illustrated in Fig. 3, consisting of a disk and lantern connected with the first of several angle-levers b, lying one behind the other,-by means of a rod g, which assists in the movement of the angle-lever, and thereby moves the visible signal as desired.

The connection of the separate parts with each other and also with the station can obviously be made in any preferred manner.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a railway signaling device, the combination with the rail, a pivoted lever, means operated from a distance for tilting the lever,
