MOSES E. NEWELL, or rnwasnsvmrn, rumors} -A'UTOMOBIIJE HEADLIGHT DIMMER.

T 0 all whom it may concern."

Be it known that Moses E. NEWELL, a

citizen of the United States, residing at .Edwardsville,.lnthe county of Madlson and State of Illinois, has invented certainmnew and useful Improvements in Automobile Headlight !Dimmers,-of which the following is a specification.

This invention relates to new and useful improvements in automobile head light dimmers The primary object of my invention is to provide a mechanism of the character specifled that will eliminate the usual head-light glare commonly encountered in passing automobiles on the street or roadway and will, at the same time, give ample or sufiicient illumination to the roadway for a distance of 40 to feet so that the driver or operator of the machine which is equipped with my invention can safely proceed and know what obstructions, if any, are in his path. The non-glare effect attained through the use of my dimmer is accomplished by catching the upper rays of light and deflecting them downwardly and forwardly, increa ing the road light for some distance and producing a stronger illun'iination than is derived from the headlight without the dimmer. In this connection, it is poii i out that the usual dimming of the head lights to avoid glare, produces such a weal: illumination of the road that it is unsafe for the'driver to proceed for any appreciable distance with his lights dimmed.

With the foregoing and other objects in View that will appear as the nature of my invention is better understood, the same con sists in the novel features of construction, combination and arrangement of parts iilustrated in the drawings and more particularly pointed out in the appended claim.

In the accompanying draw u s which are for illustrative purposes only, and are there fore not drawn to scale 1- Figure 1 is a plan view, illustrating the application of my invention.

Figure 52 is a front view.

Figure 3 is a side elevation, the dimmer hoods in lowered or operative position.

Figure 4: is a similar view, the dimmer hoods in raised or inoperative position.

The other views are details of various features of my invention.

Referring to the drawings for a more particular description of my invention and in Application filed March 12,192t .SeriaLNe-69 fl82r which drawings, like parts are designated by like reference charactersthroughout the several views, A designates the headlight casings, B the lightrbulbsand C thereflec- 60 tors of'the automobile headlights which are of'anystandard or approved construction.

Hingedly mounted 'within the headlight casings A to swing in a vertical plane, above and over the light bulbs B, are the dimmer hoods D. hen in operative or lowered position the dimmer hoods set directly over the light bulbs and deflect the upper rays of light downwardly and forwardly on the roadway. When in raised or inoperative position, said hoods permit the full unobstructed reflection of the light rays.

The dimmer hoods are carried by opposite ends of the rock shaft E, extending through and journaled in the headlight casings. daid hoods are perfectly secured to the rock shaft by the eyes or loops F fastened to the upper inner corners of the former and en circling or embracing said shaft. The rock shaft aforesaid, is provided intermediate its ends with a crank arm G, to which is connected, as at a, the forward one of open ating rod H, which extends through the radiator shell and the instrument board 5') of the machine and is provided with a lT'l-OlO or handle 0 adapted to be grasped by the otor in manipulating the same. practice, when the dimmer hoods l in raised or inoperative position, the hno'o or handle 0 of the operat g rod Z -4 against the instrument board and pull is exerted on said rod to lower 'tl e hoods directly over the light bulbs i hoods are in operative posi' :1, the rays of light are directed downward the roadway and the direct rays of 3; which would ordinarily produce r I T inter ere with the driver of an ap machine, are eliminated.

They are also provided in th vertical perforations 25, it havi on experience that some of the L, through the perforations strength of the road light ahead.

From the foregoing description, taken in connection with the drawings, is thought that the construction, operation and advantages of my invention will be readily understood without requiring a more extended en planation.

Various changes in the form, proportions and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of my invention as defined in the appended claim.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

A headlight dimmer for automobiles comprising a pair of hollow dimmer hoods provided in their top Walls with vertical perforations, said hoods hingedly mounted to swing in a vertical plane within the headlight casings over the light bulbs and adapted to set in horizontal position directly over and entirely encompassing the upper portions of the latter when in lowered or operative position whereby the upper rays of light will be deflected downwardly 011 the roadway and means under the control of the operator for raising and lowering the dimmer hoods, said means comprising a transverse rock shaft extending through and journaled in the headlight casings, loops at the upper rear corners of the dimmers embracing the rock shaft, a crank arm extending from the rock shaft and an operating rod connected with said crank arm and extending rearwardly through the radiator shell to within convenient reach of the operator.

In testimony whereof he affixes his signature.

MOSES E. NEWELL.
