SAM 1\T. WAGES, OF CORNWELL, SOUTH CAROLINA.

LOCOMOTIVE-HEADLIGHT.

Application filed September's, 1915.

0 all whom it may concern Be it known that I, SAM N. WAGES, a citizen of the United States, residing at Cornwell, in the county of Chester and State of South Carolina, have invented new and useful Improvements in Locomotive- Headlights, of which the following is a specification.

This invention relates to locomotive headlights and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a headlight especially adapted to be used upon locomotive engines and which includes means for automatically turning the lamp in a manner to cast its rays along the track when the locomotive is passing around a curve.

lln railroad track construction it is customary to elevate the outer or longer rail around a curve at a higher position than the inner or shorter curved rail, consequently the rolling stock as it passes around a curve is tilted toward the rail having the shorter curve. Along straight tracks the rails are at the same level. The fact that the rails around a curve are at different levels is taken advantage of in the present invention and as a locomotive equipped with the headlight hereinafter described passes around such a curve, the light is automatically turned or turned by gravity in order to cause the rays from the lamp to follow the curvature of the track. When the locomotive is running along straight tracks the lamp is automatically positioned or moved by gravity to cause the rays of light to travel in a straightforward direction along the track.

The structure of the device includes a frame which is applied to the forward end of the smoke box of the boiler and in which is pivotally mounted a disk for turning movement in a vertical plane. A weight is applied to the lower side of the disk and the disk is provided at its forward face with two cam arms. A shelf is located at the lower forward portion of the frame and a lug is located at the upper forward portion thereof. A standard is pivoted between the shelf and the lug and is provided at its opposite sides with outstanding arms which have rollers bearing against the forward faces of the said cams. A lamp is attached to the said standard. As the locomotive moves along the straight track the Specification of Letters Patent.

rails of which are at the same level the standard is held so that the rays from the lamp are cast in a straight forward direction along the track. As the locomotive moves around a curve and is tilted the weight at the lower side of the disk turns the disk whereby the cams which engage the rollers upon the arms swing the standard and thus the lamp is turned so that its rays are cast in the same general direction as the curvature of the track.

In the accompanying drawings :-Figure 1 is a front elevation of the headlight. Fig. 2 is a similar view showing the lamp turned with relation to the supporting frame. Fig. 3 is a front elevation of the supporting frame of the headlight with the lamp removed therefrom and showing parts thereof in sections. Fig. 4: is a vertical sectional view of the headlight. Fig. 5 is a horizontal sectional view of the headlight.

The headlight comprises a frame 1 which may be attached to the forward end of the locomotive boiler or smoke box in any suit able manner. A disk 2 is pivotally mounted in the frame 1 for turning movement in a vertical plane and a weight 3 is carried at the lower side of the disk and the said weight hangs pendent through the lower portion of the frame 1. As the weight 3 moves to one side or the other under the influence of gravity with relation to the frame 1 the disk 2 is turned in the said frame. The disk 2 is provided at its forward side with forwardly disposed cam arms at one located at each side of the center of the said disk. A bracket 5 is located at the forward side of the lower portion of the frame 1 and a lug 6 is located at the forward side of the upper portion of the frame 1. A standard 7 is pivoted between the bracket 5 and lugs 6 for horizontal turning movement. The bracket 7 is provided at its opposite sides with outstanding arms 8 having rollers 9 journaled thereon, and which bear against the forward surfaces of the cam arms i. A lamp 10 is mounted at the forward side of the standard 7. The lamp 10 may be oil, electric or any other suitable type of lamp.

When the locomotive to which the headlight is applied is traveling along straight tracks, the rails of which are at the same level, the weight 3 hangs approximately in vertical alinement with the longitudinal dimension of the standard 7 and the lamp 10 is held in a position to cast its rays in a straightforward direction along the straight track. When the locomotive is rounding a curve and tilts due to the fact that the outer rail is at a higher level than the inner rail, the frame 1 tilts with the locomotive but the weight 3 hangs in a vertical direction whereby the disk 2 is turned with relation to the frame 1 and the cam surfaces of the arms l operating against the rollers 9 carried by the arms 8 turn the standard 7 so that the lamp 10 is turned and its rays are cast in the same general direction as the curvature of the track around which the locomotive is passing. After the locomotive has passed around the curve and again moves along the straight track the rails of which are level the weight 3 assumes its normal position approximately in alinement with the long dimension of the standard 7 and the lamp casts its rays in a straightforward direction.

From the above description taken in conjunction with the accompanying drawing, it will be seen that a locomotive headlight of simple and durable structure is provided and the parts mutually cooperate with each other whereby an automatic operation is had which causes the lamp to cast its rays in a straightforward direction when the locomotiveis moving'along a straight track and which causes the lamp to cast its rays approximately in a direction of a curve when the locomotive is passing around the same.

Having described the invention what is claimed is 1. A. locomotive headlight comprising a frame, a weighted disk pivoted therein, cam arms mounted upon the disk, a standard pivoted upon the frame, a lamp carried by the standard, and arms mounted at the opposite sides of the standard and adapted to be operated by the cam arms when the disk is turned with relation to the frame.

2. A locomotive headlight comprising a frame, a weighted disk pivoted therein, a standard pivoted upon the frame, cam arms mounted upon the disk at the opposite sides of the center thereof, a lamp carried by the standard, arms mounted upon the standard at the opposite sides thereof, and rollers journaled upon the arms and bearing against the cam surfaces of the cam arms.

3. A locomotive headlight comprising a frame, a weighted disk pivotally mounted therein, cam arms mounted upon the disk at the opposite sides of the center thereof, a bracket mounted upon the frame, a lug mounted upon the frame, a standard pivoted between the lug and bracket, outstanding arms carried at the opposite sides of the standard, rollers journaled upon the arms and bearing against the cam surfaces of the cam arms and a lamp mounted upon the standard.

In testimony whereof I aiiix my signature in presence of two witnesses.
