AUTQMATIC ADJUSTING MEANS HEADLIGH TS.

Specification of Lcttefs Patent.

Patented Mar. 28,

Application. filed March 81, 191.6. Serial No. 552,688.

To all whom it may concern:

Be it known that I, Josnrn P. MoELLIo'rr, a citizen of the United States, and a res1 dent of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Automatic Adjusting Means for Headlights; and I do herebydeclare the following to be a full, clear, and exact descripportion of my .re central sectional and ,plan views of on, which form a which is automatically actuated to tion of the invention, such as will enable' others skilled in the art to which it appertains to make and use the same, reference being. had to the accompanying drawings, and to the figures of reference marked therepart of this specification.

My invention relates to railway appliances, and has particular reference to means move the headlight of alocomotive, electric car, or other vehicle of a self-propelled nature to cause the reflected light to follow the curves of a track over which the locomotive orthe like is operating.

The object of my invention is the provision o a simple and efi'icient apparatus of the class described, which is an improvement upon the apparatus described and claimedin the application for United States Letters Patent filed by me on June 10th, 1909, being Serial No. 501,444, and which is economical in its construction, positive in its action and adapted to adjust the headlight vertically as well as horizontally to cause the light rays to be directed on the track as far in advance of the locomotive as the nature of a curve which the track is following will permit.

The invention is fully described in the following specification, and a preferred embodiment of the same illustrated in the accompanying drawings, in which,

Figure l is a side elevation of the front portion of a locomotive, partly in section,

with my invention in operative association therewith. Fig, 2 is a front elevation of the same with a portion of the locomotive broken away. Fig. 3' is a plan of the lower inventidn, and Figs. i and 5 v the -:adlight supporting'hrocket.

Referring to the drawings, 1 designates any suitable form of locomotive, the front truck -2 of which is provided with a verlight for vertical portion or ledge of the bracket 10 1S down one of planes of the cam 153 and tically disposed axial trunnion or turning bolster 3, which is common in one form or another in most locomotives.

4 designates the locomotive headlight, which. is shown as having its drum or casing circuinferentially encircled by a hand 5, the ends of which are detachably secured t0- gether by a bolt or screw 6., This hand has trunnions 7 projecting therefrom at the sides of the headlight, which trunnions journal in the'ends of a semi-circular supporting cradle 8, carried at the upperend of a vertical shaft 9, thus adapting the headoscillatory movements with the trunnions 7 as its axis, or for horizontal oscillatory movements with the shaft '9 the axis.

The shaftt has its upper end journaled in a bracket 10 projecting horizontally'from the front end of the locomotive boiler, and has its lower end journaled in a bracket 11. carried by the usual front cross-beam 12 of the locomotive. The horizontally proj ecting rovided on its upper sarface beneath the orward portion of the headlight with a segmental inverted l-shaped cam 13 the point or apex of which is disposed hcneath'the central portion of the headlight when di rected straight ahead. Beneath the rear edge of the headlight the bracket 10 is provided with a'seginental ll-shaped cam 14 the top or cam surface of which is exactly the reverse of the top or cani surface of the front cam 13. The headlight is provided on its under side adjacent its front and rear edges with substantially V-shaped lugs 15 and 16, respectively, which rest upon the respective cams l3 and is as indicated. The cams 13 and 14 and the lugs 15 and 16 are so relatively arranged that when the head light is ie'straight-ahead position it is at a neutral point of its vertical oscillatory adjustinent with the front lug coacting with the central or highest point of the cam 13 and, rear lug coacting with the central or lowest point of the cam l l. A. turning of the headlight in either wa upon its vertical axis will cause the front lug to ride the downwardly declining the rear lug to ride up the reverse upwardly inclined plane of lit) wail

light on its horizontal axis for termined degree of horizontal turning either direction.

The lower end of the shaft 9 has arms 17 projecting horizontally 'lron'i tnn'iosite sides thereof laterally of the loromotive such arms being" preferably angled rearwardly from the shaft. to provide a space, between them and the cross-bean! 12 in which the arms may rock. A coupling member 18 is an- I'iBtl by eaeh arm 17 for longitudinal adjust ment thereon, it being secured in adjusted position by a set-screw 19.

Links or rods 20, 20 extend rearwartily from the 111?]1'15 1.7. 17 being pivotally attached thereto through the ineditnn ot the eonplinr a l8. 18, or in any other snitahle manner, and have their rear ends extenrlin; on opposite aides of the trurk trunnion or J, and pirot'aliy attached to ears 2t holster projecting from opposite sides of a hand or ring 22, wlneh encircles and 1S firmly clamped to auoh trunnion to turn therewith. For this purpose the hand is Fllt flll as being inatle in two parts clamped together by holts Q3. The degree of turning oi the shalt 9 tor a. predetermined turning of the trunnion $5 is regulated by an adjustment of the couplings 1.8 on the arms l7.

i wish it understood that my invention is not limited to any speeiiie ronslrurt'ion or arrangement ol' the parts except. in so far as such limitations are aprt-ilied in the rlainia and also that while parlirularly shown and descriht-d in t'UiHlt'tlitHl with a railway lot-o motive it may he used in all other woman:- lions l'or whirl] it may l e adapted o' a r progwiatr, an aulonloliilos or the like.
