SPECIFICATION forming part of Letters Patent N0. 764,229, dated July 5, 1904.

.Application filed March l0, 1902. Serial No. 97,6061 (No model.)

To rtl/ wle/me t may concern: y

Be it known that I, EDGAR A. Enwniws, a citizen of the United States, residing at Oincinnati, in the county of I-Iamilton and State 5 of Ohio, have invented certain new and useful Improvements in Headlights for Locomotives, of which the followings a speciiication. My invention relates to locomotive headlights, and especially to that class of headlights 1o in which screens are employed to reduce the glare of the light under certain conditions; and my invention consists in means by which the screen can be employed without interfer.

ing with the signal-light and without danger of injury from condensed moisture and in certain features of construction fully set forth hereinafter and illustrated in the accompany ing drawings, in which- Figure 1 is a side view of a locomotive- 2o headlight casing and reflector, illustrating my invention. Fig. 2 is afront view; and Fig. 3,

an enlarged section on the line 3 3, Fig. 52.

The casing A of the headlight is of any proper form and proportions, containing the usual lamp and reflector (not shown) and provided on the outside with an inclined frame supporting' the signal-reiieetor B, which receives a portion of the horizontal light-rays passingl through the upper portion of the 3o opening in front of the casing and projecting them upward.

In that class of headlights in which electric or other intense lights are used it is necessary to reduce the brilliancy of the light when two engines are approaching, as it interferes with the proper observation of the track and surrounding objects by the engineers, and for this reason screens or shades have been provided which can be drawn across the front 4o opening to reduce the light.

I arrange outside of the goggle-ring O, which is hinged tothe front of the case A, a vertical casing 5, adapted to receive a spring-roller 6, upon which is wound a shade 7, of any suitable flexible translucent material. This easing is extended so as to inclose a space at cach side of the frame that will receive the shade 7 when carried through a slit 8 in the frame and across the glass-covered opening .fr

in front of the frame. To thus draw the 5o shade across the opening, it is provided at the edge with a stiiI'ening-strip 9, to the center of which is connected a draw wire or cord I0, which is passed around the guide-pulley l2, outside'the casing A, and back to the cab or the engineer, and this strip is properly guided by providing it at the upper end with an eye 13, receiving a guide-rod 14, that extends across the opening a'. By this means the engineer can draw the shade across the opening 6o or relax the cord and allow it to move back under the action of the spring.

Inasmuch as the signal-reflector B covers the upper portion of the opening :1: and as it is desirable that the light-rays shall at all times fall upon this reflector, the screen 7 is made only of a height sui'licient to cover that portion of the opening below the reflector B, whereby this portion may be screened at will without interfering with the signal-light. 7o

By arranging the spring-roller and casing at one side of the structure any interference with the light or obstruction of the opening m by the casing is avoided, while any moisture which condenses on the plate I5 and 75 passes downward can escape without in any manner ai'ecting the screen or its operation.

Without limiting myself tothe precise construction shown and described, I claim- I.
