HEADLIGHT ATTACHMENT.

Application filed December 8. 1914.

To all whom it may concern:

Be it known that I, WILLIAM FRANCIS LENNON, a citizen of the United States, residing at \Villimantic, county of Windham, State of Connecticut, have invented certain new and useful Improvements in Headlight Attachments, of which the following is a full, clear, and exact description.

My invention relates to improvements in electric headlights and consists particularly in an improved appliance which may be interchangeably and adj ustably mounted upon and used with incandescent electric light bulbs, such as are employed in headlights, the object of my invention being to confine the intense rays largely to the roadway.

In the accompanying drawings, Figure l is a side elevation of my invention in place in a headlight reflector, the latter being in section. Fig. 2 is a top plan view of my invention as applied to an electric light bulb. Fig. 3 is a relatively enlarged view of the forward end of said electric light bulb equipped with my improved attachment, parts of the latter being broken away. Fig. 4 is a view of the under side of my improved attachment.

1 represents a headlight reflector.

2 represents an electric socket therein arranged to receive an electric incandescent bulb 3, any suitable type of socket being available, the particular type shown herein being a screw type, in which 3 represents the screw plug.

l represents the body of a cup-shaped protector conforming closely to the contour of one-half of the bulb 3. The said protector 4 is cut away or recessed at 5 to afford clearance for the plug 3. The opposite edge of the protector 4: is cut away at 6 to afford clearance for the pointed glass tip 3 of the bulb 3, such tip being almost universally found in glass bulbs of this character. The edge of the protector 4 is rolled up or suitably formed to provide a channel 7.

8 is a rubber band. This rubber band is seated in the aforementioned channel and extends across the

recesses

5 and 6, as shown. To apply the protector to an electric light bulb the bulb is first removed and the plugend 3 is passed through the recess 5 back of the part 8 of the band. The protector 4 is then placed down on the bulb and the part 8 of the band is stretched around the tip 3 of the bulb, thus uniting the parts. The

protector 4 is preferably madefof metal. the inner side of the same being suitably brightened as by white paint or a suitable electroplating, such as silver or nickel. Indeed it is preferable to silver or nickel the, entire protector :1, thus makin it practically invisible in the headlight and at the same time giving to the interior a proper reflecting capacity, serving to throw the light against one side of the reflector, in this instance the lower side, whereby the powerful rays of light projected forwardly by the reflector will practically lie below the horizontal dotted .line shown in Fig. 1.

There are many advantages growing out of employing this improved construction, for exa1nple, 'the'device is readily interchangeable with different lamps. The user can either apply or remove it at will. In the eventthat one lamp breaks, the attachment need not be discarded but may be applied to a new lamp. When in position it is securely held without danger of injury to the bulb since it is yieldingly held by the elastic band 8. By using a rubher or elastic band sufficient friction occurs between the band and the lamp to hold the protector 4 in I whatever position it is initially placed. Should a rubber band break a new one may be readily substituted by simply pushing it into the channeled edge. The channeled edge of the protector serves not only to hold the band properly in place but hides it from observation save as to that very small part 8 which engages the bulb tip 3 By making the protector 4 adjustable to any position around the bulb 3, it permits the use of any type of lamp socket, whereas if the protector were rigidly attached to the bulb 3 a suitable lamp socket would have to be employed to guarantee the proper positioning of the lamp, whereby the protector would be uppermost for otherwise there would be no certainty that when the lamp is secured in proper operative position the protector would stand inthe proper position to confine the powerful reflected rays to the roadway.

What I claim is,-

1. In a protecting device for incandescent lamps, a cup-shaped body arranged to cover one side of the lamp, and elastic globe-em gaging means with means carried by the body for holding said elastic globe-engaging means at the front and at the rear, whereby said cup-shaped body may be detachably and adjustably connected to the shank of the lamp and to the opposite end or tip of the lamp.

In a protecting device for incandescent lamps, a cup-sha ed body arranged to cover one side of the lamp, an elastic means carried by said body and arranged to engage the lamp at the front and rear edges of said body to adjustably hold said protecting device thereon, the edge of said body being channeled, said elastic means being located in said channel, with two openings in said channel to permit said elastic means to be engaged with said lamp. 4

3. In a protecting device for incandescent lamps, a cup-shaped body arranged to cover one side of the lamp, an elastic means carried by said body and arranged to engage the lamp at the front and rear edges of said body to adjustably. hold said projecting device thereon, the forward and rear edges of said body being recessed, the elastic means spanning said recessed portions.

4. In combination, an incandescent lamp comprising a bulb, a plug terminal at one end and a forwardly pro]ecting'-"tip at the other end, a protector conformed substantially to one side of said bulb, said protector having recesses to afford clearance for said plug and tip, an elastic band carried by said protector and spanning said recesses and arranged to ieldingly engage said plug and tip to hold the protector 111 place on said bulb.

5. In combination, an incandescent lamp comprising a bulb, a plug terminal at one end and a forwardly projecting tip at the other end, a protector conformed substantially to' one side of said bulb, said protector having recesses to afford clearance for said plug and tip, an elastic band carried by said protector and spanning said recesses and arranged to yieldingly engage said plug and tip to hold the protector, the edges of said protector between said notches being channeled to receive and hide the major portion of said elastic band.

WVILLIAM FRANCIS LENNON.
