JAMES SMITH AND SHERMAN F. WARNER, OF ELMHURST, NEW YORK.

HEADLIGHT..

To @ZZ whom it may concern Be it known that we, JAMES SMITH and SHERMAN F. WARNER, citizens of the United States, residinor at Elmhurst, Long Island,in the county of ueens and State of New York, have invented new and useful Improvements in Headlights, of which the following is a specilication.

This invention relates to headlights for automobiles orsimilar vehicles; and it has for its primary object the provision of means which will be automatically controlled on movements of the steering gear to effect corresponding adjustments of the headlight, whereby the latter will always be thrown in the direction of travel of the machine and directly in advance of the same when taking curves.

Another object of the invention is to provide an adjusting mechanism which can be connected with any standard form of machine without necessitating changes in the construction thereof.

A further object of the invention is to provide adjusting mechanism which will include relatively movable connecting sections between the steering rod and the lamp post which will adapt themselves to relative vertical movements of the steering rod and thereby eliminate strain and torsion upon the adjusting section.

A still further object of the invention is to provide means for minimizing' the friction between the lamp carrying post and the supporting brackets so as to render the posts extremely sensitive to movements of the steer-ing rod and to prevent the post from binding in its support.

lilith these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings r-Figure 1 is a top plan view of a portion of an automobile, showing the application of the head lamps thereto; Fig. 2 is a perspective view of one of the supporting brackets and the lamp supporting -post thereof: Fig. 3 is a vertical section through the post and through the supporting sleeve; and Fig. el is a section on line 41E-J1 of Fig. 1. Fig. 5 is a section through the connecting means of 'the rod for the lamp supporting post.

The automobile frame herein shown inchicles side bars 1 of the usual well known Specification of Letters Patent.

Serial No. 742,834.

construction being provided preferably at their forward ends with vertical sockets 2, which receive stems 3 which are formed integrally with lateral branches 4 of vertical sleeves 5. Said stems 3 are provided with lower reduced extremities 6, which are threaded for the reception of clamping nuts 7, and as illustrated said extremities are provided with horizontal passages S which receive cotter pins or like locking devices 9 which are adapted to underlie the nuts and prevent the same from turning relatively of their co-engaging surfaces of the sockets 2. Said sleeves 5 are provided with upper and lower annular race-way forming channels 10 and 11. The lamp supporting posts 12 are extended through the sleeves 5 and arranged wholly in spaced relation of the inner walls of the sleeves. These posts are provided with upper liXed caps 13 having portions 14 extending into the sleeves and portions 15 arranged exteriorly of the sleeves and in spaced relation thereto. The portions 14 are provided with race-way forming grooves 16, which are associated with the race-ways 10, so as to receive therewith the spherical anti-friction sustaining Abodies 19, which are adapted to sustain all portions of the heads in spaced relation to adjacent portions of the sleeves so as to minimize the friction between the sleeves and the lamp supporting post.

Each post 12 is provided with upper and lower spaced threaded portions 18 and 19 respectively, and an intervening squared portion 20, the said threaded portions being of differentdiameters, the upper portion 18 being the larger. The portions 18 receive adjustable cones 21, which are partly eXtend ed into the sleeves/5 and provided with upper race-ways 22, which are associated with the race-ways 11 so as to receive therewith' the anti-friction bodies 23. The portions 20 of the posts are fitted in correspondingly formed openings 24. in arms 25 which are disposed in rearwardly diverging relation relatively at the opposite sides of the vehicle and provided with rear depending reduced cylindrical stems 26 which extend through corresponding openings 27 in connecting elements 2S. T he lower ends of the stems 2G receive retaining nuts Q9 and locking pins 30, the latter being removably associated with the pins and adapted to underlie the nuts so asto hold the same against displacement. The members QS are preferably provided with openings 31, which extend in the direction of the stems 2G opening directly thereonto whereby `oil may be introduced to the stems and the openings 27. The threaded portions 19 of the lamp supporting post receive retaining nuts 32 and locking cotter pins 38.

The members 28 are provided with spaced ears 33, which accommodate knuckles 34 of connecting rods 35. These rods are ar? The post l2 terminates in up er forks 41 whose branches 4t2 are extende into receiving sockets '43 at the opposite sides of the headlamps. By eonnectmg the rods with the vattaching plates 36 and the members 28 as described, it is evident that they are .adapted for' substantial universal movements whereby they will be permitted to respond to movements of .the vehicle frame without being strained or otherwise affected through such movements.

From the foregoing description, taken in f Legnano' connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the -minor details of construction may be resorted to without departing vfrom the principle or sacrificing any of the advantages of this invention, as claimed.

Having thus described our invention, what we claim is ln a light su )port for vehicles, the combination with a racket having a fixed sleeve thereon, a post revolubly mounted within the sleeve and having its lower end provided with upper and lower1 spacedv threaded portions of different diameters and an intervening squared portion, a member having 'a squared opening therein adapted to lit over the squared portion of the post, a nut ad? justably mounted on the upper threaded portion of the post, and a second nut mounted on the lower threaded portionv of the post, and means on the last mentioned threaded portion of the post to prevent displacement of the last mentioned nut.

In testimony whereof we aflix our signatures in presence of two witnesses.
