WILLIAM E. TETER AND CHARLES .B. GRAY, OF DALLAS, TEXAS.
MECHANISM FOR ROTATING A LOCOMOTIVE-HEADLIGI-IT.
To all whom it may concern:
Be it known that we, WILLIAM E. Tn'rnn and CHARLES B. GRAY, citizens of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Mechanism for Rotating a Locomotive- Headlight, of which the following is a specification.
Our invention relates to a new and useful mechanism for rotating a locomotive headlight, and its object is to provide a manually operated mechanism that will enable a locomotive engineer to rock the headlight about a pivotal axis without leaving his cab so as to illuminate a curved portion of the track ahead of the engine.
A further object of the invention is to provide a device of the character described that will be strong, durable, simple and eflicient and comparatively easy to construct and also one that will not be likely to get out of working order.
With these and various other objects in view, our invention has relation to certain novel features of the construction and operation, an example of which is described in the following specification, and illustrated in the accompanying drawing, wherein:
Figure l is a view diagramatically showing a locomotive in side elevation, our novel headlight adjusted mechanism being correlated with said locomotive. F lg. 2 is a vertical sectional view of the headlight showing how the reflector is rotatably mounted. Fig. 3 is a detail sectional view showing one of the rollers adapting the headlight to undergo rotation.
Referring now more particularly to the drawing, designate similar parts in all of the figures, the numeral 1 denotes the boiler and 2 the cab of an ordinary locomotive. On the forward extremity of the locomotive there is mounted in the usual manner a headlight casing 3. Upon the floor of this casing is rigidly secured a circular plate 4. A second circular plate 5 is superimposed upon the first mentioned plate, being supported by a plurality of rollers 6 recessed inthe plate 4 adjacent to its periphery. The reflector 7 mounted within the casing is rigidly sup- Specification of Letters Patent.
Application filed May 5, 1913.
wherein like reference characters Patented Aug. 18, 1914. Serial No. 765,701.
ported at an elevation above the plate 5 by a plurality of bracket members 8. A short lever 9 is rigidly secured to the plate 5 and projects rearwardly through the back wall of the casing 3. WVith the free end of said lever is connected a swinging rod 10 joining said lever with an arm 10* carried fast upon the forward end of a rock shaft 11,
mounted in bearings 12 in the boiler l. The
shaft 11 projects at its rear end into the cab 2 and carries a gear 13 closely adjacent to the rear end of the boiler 1. The gear 13 is in mesh with another beveled gear 14: carried by the upper end of a short shaft 15 supported by a bracket arm 16. The bracket arm 16 carries a quadrant 17 adapted to be engaged by a lever 18 secured to the lower portion of the shaft 15. The parts 17 and 18 in conjunction appears to hold the refiec tor of the headlight adjusted in any desired position of rotation.
The above described mechanism enables the engineer to keep the track ahead of the locomotive well illuminated whether or not said track is curved and thus materially decreases the possibility of accidents or colli- S'rOIlS.
The invention is presented as including all such modifications and changes as properly come within the scope of the following claim:
lVhat we claim is:
In a headlight adjusting mechanism, the combination with a stationary headlight and a reflector rotatably mounted within the headlight, of a lever projecting rigidly from said reflector, an elongated rock-shaft, an arm fast upon the forward end of said rockshaft projecting toward the lever, the lever and arm being normally in planes at right angles to each other, an angularly disposed link pivotally attaching the ends of the lever and said arm, and means engaging the rear end of the rock-shaft for actuating the same.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
