LSigpit Specification of .Letters Patent. r'ii'qqitiiqf ,2511? friggin .pplicaton lil hflach 29, 1920, Serial No. 389,723,

To all wilma vir? may co'lictf'rii f Be it known that l, HARRY l?. lli-Aeration), a citizen of the llnited States, and a resident in the county oi' Be` nington and State ot' Vermontj have invented a new and improved .-eiidlili.i';.l of

vwhich the following is a i'iill, clear, and eX- act description.

This invention relates to improvements in headlights7 an'object of the invention being to provide an attachment for ordinary head? lights which will operate to prevent glare but allow full road illuminatioii-- A further object is to provide a device ol the character stated which is of transparent colored materia-l so as to color the light rays which are thrown upwardly from the headlight and at the same time permit a full glare of uncolored light rays on the road.

With these and other objects in view the invention consists in certain novel features or construction, and combinations and arrangements of parts, as will ne more fully hereinafter described and pointed out in the claims.

In the accompanying' drawings- Figure l. is a view in front elevation-illustrating my invention;

Fig. 2 is a view in section on the line 2 2 of Fig. l;

Fig. 3 is a view in section of Fig. d; i

Fig. i is a top plan view of my improved attachment;

on the line 3 3 Fie. 5 is a view inside elevation illustrating a modification; and

Fig. 6 is a view in section of Fig'. 5.

l represents the shell or casing or' an ordinary` headlight which is provided with a grooved edge 3 for the reception of a gasket i against whichthe lens or frame supporting the lens, both of which are omitted for purposes of clearness, are adapted to snugly on the line 6-6 lit to 'render the headlight casing airtight.'

As is common with headlight casings a socket 5 is provided at the rear and center thereof for the reception of an electric lamp 6.

7 represents my improved device which is in the forni of an attachment or" general cylindrical shape, but having a conical or tapering inner end 8, the latter provid-ed centrally with a ring or sleeve 9 to lit over the sochet'. metal strap i() is secured to the bottom and inner portion of the device i and is strengthened hy a hracc ll adjacent its forward end. rhis strap l() is adapted tol lie projected through a slot l2 iii the eldee of the shell l and when lient haelt airainst the shell and the lens of the reiiector closed will e securely clamped in place. i

lilyiinpioved attachment is made with an end plate 13 oi' semi-circular torni across the upper half leaving the lower halt of the outer end open so as to allow the direct rays lfroin tlievlamp to pass iorwaidlv and downwardly7 tout prevent the direct ravs from passing upwardly. The top ot the Ldevice 7 is cut out or open as shown at hl, and this opening or ciit-oiit portion extends substantially halfway around the device.

My improved device or attachment is in reality a light controlling and ray diffusing' device and is composed preferably of celluloid, although it may be made oil any other suitable transparent or semi-transparent material. The material is preferably reen in color, although it lis. of course. be understood that l do not limit *myself to the particular color of the transparent material as itvmay he of any color which will answer the purpose.

Then the device is in operative position in a headlight, the light rays Jfrom the lamp o will pass directly through the openlower portion of the outer end of the device onto the road and will also he deflected liv the iipper portion of the shell l directly down iipon the road. rlhe light rays which pass downwardly are softened hy the transi'iarent inaterial and colored before they engage the lower reecting surface or the shell and hence siicli rays which are deflected iipwai'dly are 'free from glare. The direct rays troni the lainp which pass forwardly and upwardly are diffused and sotteiiedl lov the closed upper end 13 of the attachment. i' lt will tliiis he noted that while the rays which pass either directly or are reflected ilowiiwardly iipon the road are free from the diii'iising action of the attachment, the other. rays which pass upwardly are all colored and diffused so as to positively prevent glare. i

ln the modification illustra-ted in Figs. 5 and d l illustrate a form oic my device which is composed mainly oi2 metal hat is provided in its lower portion with a transparent colored section i5.

With the modified forni of invention illustratedin Figs. 5 and 6,'the glare is further lessened; the small transparent portion l5- f Y alterations as fairly fall Within the spirit and scope of the appended claims. 'lli I claim:

l. An attachment tor headlights comprising a body of general cylindrical form ineiudng a tapering inner end adapted to inclose a lamp, said body composed of colored im transparent material, said body having a semi-cylindrical cutaway portion in its upper side, and having` a semi-circular opening 1n the lox'rerhalf of the outer end.

2. The combination with a headlight shell 125 .or casing, a socket in the center thereof, and

y 'a lamp in the socket. of a hollow cylindrical bod a sleeve or collar at the inner end of the ody positioned on the socket, said body hazen/te having an open top and an open lower outer end, a metal strip secured to the body and connected to the casing, and a brace connecting the lower portion of the body `with said strip.

3. The combination with a headlight shell or casing, a socket in the center thereof, and a lamp in the socket. of a hollow cylindrical body, a sleeve or collar at the inner end of the body positioned on the socket, said body having an oyien top and an openlower outer end, a meta strip secured to the body and connected to the casing, and a brace connecting the lower portion of the body `v,vith said strip, said casing having a slot therein, and said strip having a bendable portion at its outer end projected through the slot.

4. An attachment of the character described, comprising a body ofgeneral cylindrical form, said body having a tapering or conical inner end, a ring or sleeve in the cen- Ater of said inner end, said body having the lower portion of its outer end open, and said body having an opening or cut-ont portion between its ends which extends substantially halfway around the body.
