tion more particularly to a device of this general character capable of: automatic operation whereby the headlight will' be properly turned so as to throw the 11 hi: to one side when the locomotive to whic it is applied is rounding a curve, and=the ob ect of theinvention 'is to provide .a' device of this general character having novel and 1mroved means whereby the sup ort for'the' am is under control of a pen ulum.

T e invention consists in the detalls of construction and inthe combmation and arrangement of the several parts whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more copvement and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein-- Figure 1 is a view in side elevation of a locomotive headlight constructed in accordance with my invention, the adjacent portion of the locomotive to which it may be attached being indicated by dotted lines; Fig. 2 is a horizontal sectional view taken through Fig. 1 with the lam omitted; and Fig. is a ransvcrse vertica section taken tlnou h Fig. 1.

As isclosed in the drawings 1-1 denote spaced frame plates dispose in horizontal planes and sui ably connected one with the other by the posts or uprights 2-2 the frame ail'orded thereby being adapted to be positioned at the space now Igenerally employed for locating the headlig t on a locomotive.

Mounted in the plates 1-1 and adjacent the forward marglnal portions thereof at substantially their centers is the vertical shaft 8 having fixed thereto the table or platform 4, such table or platform 4 being preferably circular in form and projecting a predetermined distance beyond the plates 1-1 and produced on such projected portion 5 of the table or support are the uprights 6 6 between which is adapted to be positloned the lam 7 proper, said lamp being held against displacement by the clamping bar 8-coactin with the uprights 6-6 in a manner whic is believed to be well known and a further detail thereof is thou ht to be unnecessary as this arrangement orms no particular feature of my presentinvention. Tothe rear of the platform or table 4 and in alinement with the table 3 and suitably secured in the frame plates 11 is the verticallyv disposed rod 9 which is adapted to serve as a fulcrum for the lever member 10, such lever member 10 having produced at a predetermined point intermediate its length the elongated opening 11 extended longitudmall of the lever and through which the re 9 is adapted to pass. The forward end portion of the lever is reduced, as at 12, and such reduced ortion is so dirooted as to loosel projectt rough an openmg 14 produced in the table or platform 4 at a point substantially central of its radius, such openin 14 being positioned in alinement with te shaft 3 and the rod 9 when the lam is in position to direct its rays directly orward of the locomotive. In the opposite end portion of the lever member; 1 is reduced a lon itudinally directe elonga ed opening 15 t rough which projects the pendulum bar 16 which bar is swingingly supported from the forwardly projecting arm 17 carried by the upper extremity of the upright 18 supported in position by the frame plates 1-1 and disposed in a inement with the shaft 3, hereinefore referred to. To the lower extremity of the pendulum bar 16 is ailixcd the weighted mass 19, such weighted mass being referably composed of a suitable member ormed to ailord an olon atcd body with the opposite faces thereo flattened and disposed in parallel planes with the connection between such mass 19 and the pendulum bar 16 being at substantially the center of such mass, for purposes which are believed to be clearly ap arent.

t is thought to be obvious that upon the locomotive taking or rounding a curve the mass 19 will serve automatically to main tain the pendulum bar 16 in vertical position with the result that the table or support 4 will be 'caused to rotate through the medium of the lever member 19 in a direction corresponding to the curve of the roadway. The extent of the axial movement of the table or an port 4 being dependent upon the extent or agree of leanin of the locomotive together with the lengt of the pendulum bar 16. It is therefore thou ht to be obvious that the turning of the ta is or latformd will cause the lamp 7 to properly illuminate the roadway as the locomotive is making a turn.

In order to prevent the weighted mass or body 10 from undue lateral movement or vibration as would otherwise tend to interfere with the .successful operation of the device, I have such body 19 mounted to travel between the parallel ide plates-20, the s ace between such p ates beingbut slight y in excess of the transverse diameter "of the body 19. The speed of the lccomotive in transit tends to cause the weighted mass or body 19. to bear againstor contact with the rear of the guide lates 20a ndi.in order toeliminate theresu tant friction I suitably mount in such rear plate 20 a pl ralityof vertically disposed rollers 21 serv ing as an anti-friction means to relieve the weighted mass or body lill of any ossible' frictional resistance, The forwar guide late 20 serves as a means for limiting the ownward movement of the lever 10, such lever being adapted to rest upon the'upper ed e thereof. rom the foregoing description, it is thought to be obvious that a headlight for locomotives constructed in accordance with my invention is of an extremely simple and comparatively inex ensive nature and is particularly well a opted-for use by reason of the convenience and facilitywit which it may be applied in osition and by reason of the certainty wit lamp proper may be cause to direct its ra s alon the roadway at all times and it will also e obvious from the foregoing description that my invention is susce tible of some change and modification wit iout material departure from the princi les and spirit thereof and for this reason do not wish to be understood as limitiii myself to the precise arran emcnt and ormation of the several parts erein shown in carrying'cut my invention in practice. claim:
