It will thus be seen from the foregoing description, that a dirigible headlight has been provided which is of such construction as to enable the same to be readily and easily installed on the front of a locomotive and will furthermore at all times be positive and efficient in its operation so as to insure the proper illuminating of the tracks ahead of the locomotive.

lVhile I have shown the preferred embodiment of my invention, it is to be under stood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit or sacrificing any of the advantages of the ap pended claim.

lVh-at is claimed is A dirigible headlight for locomotives comprising in combination, a base, a vertical post supported thereon, a headlight casing adapted to swing on a vertical axis on the upper end of said post, a closed liquid container mounted on the base rearwardly of the standard, a pair of upstanding ears formed on the forward and rear ends of the container, the top of said container being pro vided with a transversely extending slot, an oscillatory shaft journalcd at its respective ends in said upstanding ears, intermeshing segmental gears carried by the bottom of the rear portion of the headligln casing and the forward end of the oscillatory shaft respectively, and a pendulum depending from the intermediate portion of said oscillatory shaft through the slot in the top of the casing, the lower end of the pendulum being operable within the liquid in the aforementioned container.

In testimony whereof I afiix my signature.
