HEADLIGH DIMMER.

, Application filed January 13, 1926. Serial No. 80,920.

. ment, to eliminate the glare of the headlights of an automobile, and also means to enable the ready application of the device to the standard type of head-light.

Another object of the invention resides in the provision of readily attachable clamp ing bands adapted to carry the dimmer hood and the bearings for the hood actuating shaft.

A third object of the invention resides in the provision of readily attachable clamping bands adapted to carry the dimmer hood, the bearings for the hood actuating shaft, and means to conceal the band clamping means to render the device more artistic in appearance.

Other objects of the invention are mentioned and described herein.

The preferred embodiment of my invention is illustrated in the accompanying drawing in which Figure 1 is a side elevation of an auto head-light showing my improved dimmer mounted thereon; Fig. 2 is a front elevation of an automobile illustrating the application of my invention to the headlights thereof; Fig. 3 is a top plan view of one of the dimmer hoods and the actuating elements connected therewith; Fig. 4 is a fragment of one of the hood carrier bands showing one shaft bearing element applied thereto; Fig. 5 is a view of the same element at right angles thereto; and Fig. 6 is a section taken on line 6-6 of Fig. 4E.

Similar numerals of reference indicate like parts throughout the several views on the drawing.

Referring to the details of the drawing, the numeral 1 indicates an automobile fragment provided with the two spaced headlights 2, 2 suitably mounted upon brackets 3, 3 secured in the frame of the car in the usual manner, which said brackets may be connected by a transverse rod 4 to steady the lamp unit.

The invention herein contemplates a glare eliminating hood or dimmer 5 carried by each of the lamps 2 and movab-ly mounted upon a split clamping band 6 which is readily attachable to and removable from each lamp, as hereinafter described, together with means operative from the auto dash for simultaneously actuating said dimmer hoods.

In Fig. 1 of the drawing the normal position of the hood 5 is indicated by the full lines thereof, and the dottedlines thereof indicate the depressed or glare eliminating position thereof. 1 Both hoods 5, and the two bands 6, respectively, are of similar construction and a description of one of each will suffice.

Each band 6 is preferably made of sheet or strap metal and divided, and formed circularly to encompass the cylindrical body of the lamp 2, the division point of the band being provided with integral end lugs '7 and 8 in'which the clamping screw 9 is mounted. The outer end of band lug 8 is extended at 10 and downwardly, at right angles, to cooperate with lug 7 to partially conceal the screw 9. The arch-like hood 5 is tiltably arranged above the band 6 and is provided with a pair of spaced hinge lugs 11 which are hingedly connected with corresponding hinge lugs-12 rigidly connected with the band 6 and projecting forwardly therefrom above the divided portion of the band. And each hood 5 is provided with a single arm 18 extending laterally from one side thereof and adapted to pivotally carry the forward end of the actuating link 14, the other end of said link being pivotally connected with the outer end the lever arm 15' at 16, said lever arm being rigidly secured to the horizontally arranged rock-shaft 17 which extends transversely of the car front and between the lamps 2 and is ournaled at its opposite ends in the bearing eye 18 of the element 19. The bearing element 19 is secured to the upper face of the band lug 8 by the head of the screw 9 and is provided with the extension 20 which is right angularly bent downward to cooperate with the band lug 7 and the lug extension 10, to effect complete concealment of the screw 9, Fig. 6.

The numeral 21 indicates a coil tension spring the lower end whereof is anchored in the rod l, the upper end thereof being connected with the arm 15, adjacent the outer end thereof, to normally hold the hood 5 elevated. The numeral 22 indicates an arm depending from the rock-shaft 17 and rigid Obviously, the full line position of the hood, e.- tte sd;i tefsdtwi ing, efteets'the' full and un immedli-ghtr 'ayfroin the lamp. To dim the light theoar driver tilts the hand lever 2% ,tothecdotted line position thereof, as illiistfated in 1, thereby depressing the front end oft-lie hood 5 to the dotted line position thereof. Upon release of the lever 24 the e011 'spi'ing- 21 re traets the parts to the original, or fnll line, position thereof, said lvef sga ifig the end Wall of the slot 26 which serves as a stop th reioi.

I claim:

The combination with a vehicle headlight, of a divided band encompassing said head-light, said band being 'provided ivith a pair of spaced cla npin 'mgs, one of lugs being extnfleda'ngiflarly to jooopeiate with the other, scfew means for clamping s is b se-eb ttisa d h ti s te screw means blngfll'ifitl'l'ttd "in said band ln'gs, a dimmer hojod tiltably mounted upon said rhenf izmes sfihe tm.t k -ft bearing ele- .dimriir teed i'oek shafgand means eonneotd with saiid ij'ockshaft and operable from the vehicle dash for controlling the movement of said shaft and thereby said dimmer hood.

In Witness whereof I have hereunto'aflixed my signiitur this-8th day of January; 1926.

G'EYER.
