UNITED S'Ifiilfl'ES PETER L. CHARLEBOIS, F PORTLAND, OREGON.

GLARESHIELD.

To all whom t may concern:

Be it known that I, PETR'L. CHARLEBoIs, a subject of the King of Great Britain, residing at Portland, in the county of MultnomahV and State of Oregon, have invented certain new and useful Improvements in Glareshields, of which the following is a specification.

This invention relates to certain new and useful improvements in glare shields and has for its primary object to reduce and practically eliminate the blinding glare `of headlights, spotlightsl and the like of automobiles to prevent the glare or light rays of the lamp being projected above the horizon- Y tal axis of the lamp for protecting the drivers of approaching vehicles.

Another object of the invention isv to provide a glare shield in the form of an arched hood adapted for mounting upon the forward edge of a lamp casing and being in the form of-a hood positioned forwardly of the lamp casing and substantially covering the upper portion thereof above the horizontal median lineand embodying a reflector in the hood forfdirecting the light rays downwardly, the forward edge of the hood having a flat plate section to prevent the projection of the light rays above the horizontal axis of the lamp.

With the above and other objects in view that will becomeapparent as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed. i

In the drawing, wherein like reference characters designate corresponding parts throughout the several views,

Figure l is a vertical longitudinal sectional view of a glare shield constructed in accordance with the present invention, the portion of a spot light lamp casing being illustrated by dotted lines with the glare shield operatively mounted thereon,

y Fivure 2 is a top plan view of the glare shiel and Figure 3 is a fragmentary rear elevational view of the shield. i

.Application led November 6, 1924. Serial No. 748,183.

Referring more in detail to the accompanying drawing, it being of course, understood that the glare shield is capable of being mounted upon projection lamps of different types, such as the headlight lamps or spotlight lamps generally associated with motor vehicles, there being illustrated by the reference numeral l, a spotlight lamp casing upon which the glare shield is mounted.

The glareshield embodies a split clamping ring 2 carrying outwardly directed lugs 3 that are secured together in clamping engagement with the forward edge of the lamp casing l by the set screw 4 passing thru 65 said lugs as shown in Figs. l and 3. The hood portion of the shield embodies a horizontal wall section 5 that is longitudinally curved asshown and preferablyforms an integral part of the clamping yring 2 as 70 illustrated in Fig. l, the wall section 'having its opposite sides terminating at a point slightly below the transverse median line of the lamp casing l. A. downwardly directed inclined wall 6 projects forwardly 75 ofthe horizontal wall section 5 with the lower forward edge thereof of curved formation as illustinted by'Ai the reference numeral 7 terminating in a horizontal flange 8, the forward curved edge 7 of the inclined 80 wall 6 merging into the opposite lower ends of the wall section 5.

A transversely curved and forwardly declined reflecting wall 8 has its opposite edges secured to the lower side of the wall sections 5 and 6.of the hood, the reflecting wall 8 being longitudinally arched as shown in Figs. l and 3A with the forward edge 9 of the arched portion of the plate terminating slightly in rear of the forward portion of the flange 8 of the hood section 6. A substantially rectangular fiat wall section 10 projects forwardly of the reflecting wall 8 and also outwardly of the lower flanged edge of the hood section 6 with the opposite side 95 edges l1 of the plate l() forming continuations of the side portions of the hood flanges 8. The rear transversely arched edge of the reflecting wall 8 has its central portion disposed shghtly above the horizontal axis of tions of the wall and hood sections 5 ando,

with the rear edges `.thereof anchored in the clamping ring 2 as shown.

From the above detailed descrip'tionof the invention, it is believed that the construction and operation thereof 4will at once be understood, it being noted that the light rays from the lamp inthe lcasing` 1 will be deflected by the reflecting wall 8 in a downwardly rand lateral direction while the horizontal wall section i0 prevents the upward .projection of the light rays'a-bove the horizontal axis of hthe lamp casing. The 'side guards 'l2 tend to concentrate the light rays and eliminate Vthe lateral dispersion thereof. The shield is extremely simple in construction andinay be attached to the ordinary head klamp or spotlight of an automobile.

' `While thereisherein shown -and described the preferred .embodiment of the present invention, it is nevertheless to be understood that minor changes .may be made therein without departing from the spirit and scope ofthe invention as claimed.-

What is claimed as new is l. In a `glare shield of the type described, a clamping ring a declined transversely curved hood section rhaving its linner edge held iii spaced relation to the ring by Ya transversely flat wall and projecting forwardly of said ring with the opposite side edges thereof terminating adjacent the horizontal axis of the ring and a transversely curved 'forwardly `arched declined reflecting` .-wall inclosed in thehood section.

2. lIn a. glare shield of the type described, a clamping ring, a declined transversely curved hood section having its inner edge held in spaced relation tothe ring by a transversely fiat wall and ,projecting forwardly of said ring withthe opposite side edges thereof terminating adjacent the hor 1izontalaxis of the ring-and a-transversely curved forwardly arched declined reflecting wall inclosed in the .hood section', with the 'forward edge ofthe arched portion of the reflecting wall terminating inwardly of the forward edge of .the 'hood section.

3. In a glare shield of the type described. a clamping ring, ia declined transversely vcurved hoodsection projecting forwardly of the ring with the oppositeside edges thereof 'terminating adjacent the horizontal axis o'f A'the ring, a transversely V.curved forwardly 'Y arched .declined reflecting wall linclosed rin Lthe'hood section with Ythe forward edge of n a clamping ring,

the arched. portion of the reflecting wall terminating inwardly of the forward edge of thehood section, and a horizontal wall section carried by the forward edge of the reflecting wall and projecting` forwardly of the hood section.

4;. ln a glare shield of the type described, a clamping ring, a declined transversely curved. hood section projecting forwardly of the ring with the opposite side edges thereof terminating adjacent the horizontal axis of the ring, a transversely curved foiwardly arched declined reflecting wall inclosed 'in the vhoodlsection with the forward edge of the arched portion of the reflecting wall terminating inwardly. of the forward edge .of the hood section,'.and the rear edge of the reflecting wall having its central portion spaced above the horizontal axis of the ring while the opposite side edges thereof are spaced below the horizontal axis.

5. In a glare shield of the typevdescribed, va clamping ring, a declined Atransversely -curved hood section .projecting forwardly of Ythe ring with the opposite side edges thereof terminating adjacent the'horizontal axis of vthe ring, a transversely curved forwardly arched declined reflecting wall inclosed in the yhood section'with the forward edge of` the arched portion of the reflecting wall terminating inwardly of the y'forward edge of the hood section, .a horizontal wall section carried by the forward edge of the reflecting wall and projecting forwardly of the `vhood section, and the rear edge of the reflecting wall having its central portions spaced above the horizontal axisr of the ring while the opposite side edges thereof are spacedbelow the horizontal axis.
