To all whom it" may concern:

Be it known that 1, Finance JENKINS, a

citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented.

new and useful Improvements in Dimmer- Shields for Lamps, of which the following is a specification.

My invention relates to new and useful improvements in dimmershields for lamps and has for its object to provide an exceed ingly simple-and eflective device of this character, whereby the rays of light issuing from a lamp will be prevented from striking the eyes of pedestrians, drivers oi other vehicles or beasts of burden traveling along the roadway which is being traversed by the vehicle carrying lamps equipped with my improvement. I

A further object of the invention is to provide a new and improved construction for fastening shields of this character to the lamp rim.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by claims.

In order that those skilled in the art to which this invention appertains may under-- stand how to make and use the same, I will, describe its construction in detail referring; by numerals to the accompanying drawings forming a part of this application in which- Figure 1 is a side elevation of a lamp showing my improved dimmer shield applied thereto.
