APPLICATION FILED DEC. 6 I916- Patented Sept. 21,1920.
z'e sharner ,onirso srATEs JOHN GRIESHAMER, or JACKSONVILLE, FLORIDA.
\ AUTOMOBILE-LIGHT DIMMER.
Specification of Letters Patent.
"Patented Sept. 21, 1920.
Application filed December 6, 1916. Serial No. 135,443.
To all whom it may concern:
Be it known that I, JOHN GRIESHAMER, a subject of the Emperor of Germany,residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in"'Automobile-Light Dimmers; and I do hereby declare the following to be a full, clear}, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.
This invention relates to new and useful improvements in headlight constructions and has for its primary object the provision of a body and reflector construction that will deflect the largest proportion of ther'ays of light toward the ground to prevent blinding of approaching traffic and the loss of light which does not strike the ground, but still will permit a small amount of light to shine straight ahead. or in a horizontal plane to moderately illuminate objects in the roadway at a distance'and render comparatively safe driving at night time.
Another objectQof this invention isthe piovisionof'means for establishing a connection between the reflector and body at their front endsfwhich firmly supports the reflector and is-also cooperated with by the lens supporting door when in a closed poition to prevent any relative movement of the reflector and the lens.
A still'further object of this invention is the provision of a headlight construction of the above stated character, which shall be simple, "durable and cilicient, and which may be manu factl-ired and sold at a comparatively" low cost.
With these and other objects in view as will become more apparent as the description proceeds, the invention consists of certain novel features ofconstruction, combination and arrangement of parts as will be hereinafter claimed.
For a complete understanding of! my invention, reference will be had to the following description and accompanying drawmore fully described and ing, in which: A
1- Figure 1 is a topcplan view ofla headlight my invention, 1'
F ig. 2 is'af vertical sectional view-of the same.
Referring in detail to the drawing, the nuconstruction constructedfin accordance with mural 1 indicates the body of the lamb having oppositely disposed ears 2 for receiving the ordinary lamp supporting standards of an automobile. Located within the body 1 is a suitable reflector 3 which has formed in the rear wall thereof a socket 4 for receiving an electric lamp 5. The rear Wall of the body lis provided with an opening in rommunication with the socket 4 to permit an electric terminal to be inserted therein. (The forward edges .of the body 1 are bent inwardly to ,form an annular flange 6 over which the edges of the reflector 3 are bent as illustrated at 7 to securely hold the relegtor 3 within the body 13'. A suitable door 8 is secured to'the body 1 as illustrated at 9 and carries a lens 10 which bears against the edges of the reflector 8. The; upward end of. the body 1 is cut away in the direction ed within the bottom of the reflector 3 and body 1 and is of a smaller size than the elec' tric lamp 5 to provide a pilot light to be. used when the lainp is employed in cities or illuminated places.
A substantially arch shaped hood 12 has i formed thereon a flange 13 which is bolted or otherwise secured to the door as illustrated at 14:. The hood 12 is provided with an opening15 to receive a set screw 16 which extends through an elongated slot 17 in an extension hood 18 whereby the extension hood 18lis adjustably secured to the 'hood 12, In "operation, when the rays of light from the electric lamp 5 arereflected from the body by the reflector 3, the upper portion of the rays will shine against the hoods l2 and 18 and be directed downwardly upon the ground, thus preventing the rays of light tfrom shining in the eyes of approaching trafiic. 13y releasing the tension of the set screw 16, the length of the hoods 1.8 and 12 may be adjusted so as to regulate the amount of light to shine directly ahead of the lamp.
While I have shown and described the preferred embodiment of my invention, it
wvill-be understood that minor changes in construction, combination and arrangement of parts may be made Without departing from the spirit and scope of the invention as.claimed.
Having thus described my invention, what I'claim is:
A headlight comprising a subsancielly tubular shaped body and reflector, one ii"- ting Within the other and each being; tapered to provide large and smell front and rear ends respectivciy, conceived rear wells o1osin; the rear ends of the body and refiec'izor, an electric lamp socket formed in the upper portion of the roar wail of the reflector receive an electric lamp to support the same adjacent to the highest point of said reflector and said socket shutting the rear We of the hody to aid in supporting the redstor therein, said body and refiertor having their large forward ends disposed on :1 downvurdly inclined plane to provide the great est reflected surfzice. or" the reflector nppep most and to permit she .lergesi; proportion of rays of iigh'i: to escape in a downwardly and forwardly direction, means securing the reflector to the body so as 120 sngiport said re'fieeior Within the body and in spaced relation iiereto, and a hood carried by the body and extending to a point in a plane below the electric light.
In testimony whereof I effix my signature 25 in presence of Mm WitTiEGSSQS.
