RAILWAY SIGNAL.

Application filed February 24, 1926. Serial No. 90,316.

My invention relates to signals of the type used along railway tracks for the guidance of trains, and more particularly to appliances of this kind employing targets during the daytime and lamps at night.

One object of the invention is to provide a signal of the kind mentioned in which the lamp and the target are built as a unit.

A further object of the invention is to fit the target to serve as a base for the lamp and also as a fuel tank therefor. 7

Another object of the invention is to construct the same of few and simple parts for production on an economical basis.

lVith the above objects in view, and any others which may suggest themselves in the specification and claims to follow, a better understanding of the invention may be obtained by reference to the accompanying drawing, in which- Figure l is a front elevation of the novel signal;

Fig. 2 is a side elevation thereof; and

Fig. 3 is a section taken on the line 83 of Figure 1.

Referring specificaly to the drawing, 5 denotes a fragment of the post usually projected from a switch or other track control for signalling purposes. The operation of the control imparts a quarter-turn to the post. hen the latter carries a target and a lamp, a positive or safe indication is evidenced in the direction of the trafiic by.

the edge of the target and a green light from the lamp; and when the post turns to indi cate a negative or danger sign, the face of the target-painted red-and a red light from the lamp show.

In the present instance, the customary sheet metal target is replaced by one of cast ironmarked 6-which has the circular form, the proper size and the red color on both sides, as in the case of the standard target. The thickness of the new target is however much greater and the interior hollow to enable the target to serve as a fuel tank or fount for the lamp 7. The latter is of standard design, having two opposed green lenses 8 and adjacent red lenses 9. The fount 6 is made with a neck portion 10 into which the attaching nipple 11 of the lamp is screwed, the lamp wick 12 depending in the fount per showing in Fig. ure 3.

The fount is cast with a filler neck 13 at one side, provided with a cap 14.

The bottom of the fount is extended to form a'socket 15 which fits over the post 5; and the assembly is transversely bored to receive a securing pin 16. To check vibration, a set screw 17 is tapped through the socket wall from, one side to bear against the post.

While the sides or faces of the fount are painted red, the periphery or edge thereof is colored green. of the device is seen as in Figure l the fount is taken as a target in the danger position, and when the target is not visible because of darkness the same signal is given by the illuminated red lenses of the lamp,

hen the signal changes to indicate a clear road, the green edge of the target becomes clearly visible in the daytime.

It is thus seen that a compact signalling device 'is had, which gives greater utility to the target than heretofore in that (1) it shows a green safety signal instead of but a thin edge, (2) it functions as a tank or fount with a large capacity of fuel, obviating the necessity of frequent filling, and (3) it furnishes a heavy and firm base for the lamp, so, that the latter is not subjected to excessive rod-bed vibration and can operate for long periods without attention or repairs.

1 claim p 1. A railwaysignal comprising a fuelfount having the appearance of a target, and a signal lamp mounted on the fount in co-ordination with the indications of the target.

2. A railway signal comprising a standard signal lamp, and a fuel-fount base for such lamp having target-shaped opposite faces in coordination with the danger signal of the lamp, and adjacent faces in co-ordination with the safety signal thereof.

3. A railway signal comprising a target in the form of a hollow cylindrical vessel, the ends of the latter serving as a danger signal and the periphery as a safety signal.

4. A railway signal comprising a standard signal lamp, and a target in the form of a hollow cylindrical fount for said lamp, the ends of the fount serving in co-ordination with the danger signal of the lamp, and the periphery of said fount serving in coordination with the safety signal thereof.

In testimony whereof I aflix my signature. v
