The primary object of my invention is to ings, big. 1 shows a locomotive A, having provide a railway signal which is simple and a pair of signals of my invention mounteddurable in construction, andinexpensiveto thereon.

The base a has an upturned extension at which receives a vertical pivot a atv the lower end of the casing. An opening I) approximately s uare is provided in the extension at and be ow this opening is a round socket which receives the pivot a By reference to Fig. 6 it Will be observed that the lower end I of the signal case is round at the lower end and square above to fit in the above described socket. When the si nal is not in use and it IS desired to change t e position of thecase,
' the signal case is raised until the square portion is disengaged from the holder and the case can beturned'so that it is located in an edge-on position with reference to. the direction ofmotion of the locomotive, the pivot.

1. A railway signal, comprising a case adapted to be pivotally mounted upon a locomotive and having a lateral opening and a guideway projecting laterally therefrom, a standard mounted in said case and having a signal disk, said disk being adapted tomove in said guideway when displaced from the 2. A railway signal comprising a case mounted upon a locomotive and having a lateral opening and a plurality of guides projecting laterally therefrom a plurality of signal disks differing one from the other in form and color. pivotally mounted in said and having a lateral .openin case, said disks being adapted to be laterally displaced through said opening and being adapted to move in said guides, means for holding said disks in said case, and meansfor holding said disks in a set position.
3. -A railway signal, comprising a case adapted to be mounted upon a locomotive member projecting laterally t ierefrom, said member having a plurality of guide grooves,
one edgethereof, said disk being pivotally mounted in said case, a catch .upon said case adapted to engage with said notch to hold said standard Within said case, and a catch upon said guideway adapted to engage with said notch to hold said standard in set position.
