Oct. 28, 1941. P. MINCHILLO NONGLARE HEADLIGHT BULB FOR AUTOMOBILES Filed June 20, 1940 Patented Oct. 28, 1941 NONGLARE HEADLIGHT. BULBFOR AUTOMOBILES PasqualeMinchillo,'Medford, Mass. Application June 20, 1940,1Serial No. 341,425

2 Claims.

This invention relates to new and useful improvements in an non-glare headlight bulb for automobiles.

The invention proposes to characterize the headlight bulb by the fact that it comprises a standard automobile headlight bulb having a glass bulb, and a plurality of opaque dots on the bulb material to make it non-glare.

More specifically, the invention proposes to form the dots by painted or printed or other material preferably engaged on the outer surface of the bulb.

Still further the invention contemplates several modified forms in which the dots are arranged at different areas on the glass bulb.

Still further the invention contemplates a modified form in which a glass shell made of sections is mounted on the glass bulb and is provided with opaque dots alignable with the opaque dotsof the glass bulb and adapted to be adjusted to various positions in partial aligmnent or completely out of alignment, as desired, to vary the non-glare effect.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly. set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a side elevational view of a reflector and bulb constructed in accordance with this invention.

Fig. 2 is a front elevational view of the bulb, per se.

Fig. 3 is a fragmentary enlarged sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a fragmentary side elevational view similar to a portion of Fig. 1 but illustrating a modified construction.

Fig. 5 is another fragmentary side elevational View similar to Fig. 1 but illustrating a still further modified form.

Fig. 6 is another fragmentary side elevational view similar to a portion of Fig. 1 but illustrating another modification.

Fig. 7 is a fragmentary sectional view taken on the line 'l-I of Fig. 6.

Fig. 8 is a fragmentary sectional view of a nonglare bulb constructed in accordance with this invention and shown applied to a reflector.

The non-glare headlight bulb for automobiles, in accordance with this invention, comprises a standard automobile headlight bulb l having a .glass :bulb rillv and a socket portion l (W. The. bulb is intended to engage within theusual socket II of an automobile headlight having areflector l2. Thus :far the device ;is conventional. However,

.itnow departs in the fact that the glassbulb 10 is provided with a plurality of opaque dots l4.

'Thesedots aretrelatively closely spaced together.

Preferably, the dots are approximately oneeighth of aninchin diameter. :Sixteen to twenty of them arearranged in. a square inch of area. These dots I4 may belpainted, printed .or in any othermannerformed on .thematerialof the glass bulb.

However, they must be formed of material which is opaque, preferably blackiii .color.

In the form of the invention illustrated in Figs.

.1 170.3 the dots 1:4 are arranged on-the front portion of the bulb l0.

:passing throughv the front .ofthe bulb.

.In.Fig..4 :a modified form of the invention has been disclosed which is substantially identical to the. prioriform, distinguishing merely in the, fact :that opaque :dots ,l 4' .are .arrangedupon the sides of the bulb. These opaque dots cut down the glare of the reflected rays of the bulb.

In Fig. 5 another form of the invention has been disclosed in which the bulb is provided with opaque dots I4 on its front face and opaque dots I4 on its side. This bulb may be advantageously employed as a headlight for vehicles since it cuts down both the glaring direct, and the glaring indirect rays of the lamp.

In Figs 6 and 7 another form of the invention has been disclosed which distinguishes from the prior form in the fact that an arrangement has been provided whereby it is possible to control the degree of glare of the headlight. It should be understood that as the glaring rays are cut down the light of the bulb is also cut down. For this reason it may be desirable to permit more or less of the glaring rays to pass.

More specifically, there is a glass shell l5 fashioned to snugly fit about the glass bulb Ill This shell I5 is made from two half sections I5 and I I5 Each of these sections is mounted in a substantially U-shaped half ring member I6 and "5 respectively. These half ring members together encircle the base portion of the bulb. Fastening elements I! engage through adjacent end portions of the substantially U-shaped half ring members l6 and I6 to releasably connect them together. The shell 15 is provided with a plurality of opaque dots [8 arranged to normally align with the dots l4 and Hi. When desired the fastening elements I! may be loosened, to

which connect together the adjacent ends of the half ring members Hi and lB In other respects this form of the invention is similar to the pre vious form. I

In Fig. 8 another modified form of the invention has been disclosed which distinguishes from the prior form in the fact that the non-glare headlight comprises a standard automobile headlight bulb having a glass bulb l0 provided with a plurality of pimples or projections 10 upon its outer surface. preferablyone-eighth of aninch in'diameter and arranged approximately 16 to 20 per square inch. The outer surfaces of these projections lll are covered with opaque material 20. This material These projections are of opaque closely spaced non-reflecting dots arranged circumferentially on said glass bulb, a glass shell completely encasing said glass bulb, a plurality of opaque closely spaced non-reflecting dots arranged circumferentially on said glass shell and in aligned positions with the dots of said bulb, and means for rotatively supporting said shell on said bulb, whereby vv said shell may be turned relative to-said bulb to move said aligned dots out of alignment, said shell being formed from two half shell sections engaging said glass bulb, said means, comprising a half ring substantially U-shaped member rigidly mounted on the base of each of said shell sections and engaging around said glass bulb at its base, and means for releasibly connecting together the [adjacent ends of said half ring substantially U- preferably is black paint having heavy, pigments.

In other respects'this form of the invention is similar-to the previous forms, and like parts are identified by like reference numerals.

It is to be understood that the opaque dots may be of any desired size and may be formed in the" glass during the manufacture of the bulb.

While I have illustrated and described the preferred embodiments of my invention, it .is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by States Letters Patent is: p 1. A non-glare automobile headlight bulb, comprising a lamp having a glass bulb, a plurality United shaped members.

2. A non-glare automobile headlight bulb, comprising .a lamp'having a glass, bulb, a plurality of opaque closely spaced non-reflecting dots ;arranged circumferentially on said glass bulb, a

.glass shell completely encasing saidglass bulb, a a

plurality ,of opaque closely spaced-nonereflecting dots arranged circumferentially on said glass shell and in aligned positionswith the dots of said bulb, and means for rotatively supporting said shell on said bulb, whereby said shell may be. turned relative to said bulb, to. move said aligned dots out of'alignment, said shell being formed from two half shell sections engaging said glass bulb, said means, comprising ,a' half -ring substantially 'U-shaped; member rigidly mounted on the base of each ofsaid; shell sections and engaging around said glass bulb atits base, and. means for releasibly connecting together the adjacent ends of said half ring substantially. Uf-

shaped members, comprising outwardly. extending lugs formed on' the adjacent ends of said half ring substantially U-shaped'members, and screws threadedly engaged through said lugs. PASQUALE MINCHILLQ;
