With the above and such other objects lde plates l0 can be secured to the arm,

as at 10 to hold the inner ends of the plates 4, t e arm being cut away to provide a seat 10 for the side plates.

From the foregoing it Will that the transparent plates 4 are adapted to protect the body 2 from the forces of nature, the plates 4 eing made of glass or other transparent material having a flat smooth surface being readily cleaned and maintained in such condition that the colors carried by the inner faces of the plates 4 or be observed in the scope of the appended claim the outer faces of the body 2 can be readily In tie draWing:-Figure l is an elevaobserved by an engineer or motorman. The tion 0 a semaphore arm in accordance With coloring matter carried by the plates 4 is intensified by the coloring matter carried by the outer faces of the body 2, and should the transparent plates 4 be broken, the coloring expense of maintenance reduced to a minimum.

I reserve the right to make the plates 4: in sections, as shown in Fig. 1 of the drawing, whereby various colors can be displayed u on the semaphore arm, and with the channel-shaped holders (3 and 7 made of a non-corrosive material, the life of the semaphore arm is materially increased and the colored to correspond to the color of the face of the signal portion with which it contacts.
