all fwhom may concern Beit-known thatl, JOHN -L. DAY, a Cltl of the United States of America, reside: g at Memphis, 'in the county, of, Shelby. and State of Tennessee, have invented cer-v tai'n new and useful,Improvements in Am tomobile-Lamps, of whichthe following is a specification. I r

My present invention relates to improvements in automobile lamps, and is designed particularly with aview to simplifying automobile lights in certain details. In many rear or tail lights for automoe biles as at present in use, the lamps are complicated in construction, are difiicult in manipulation, comparatively expensive in cost of production-due to their numerous parts,

and the glass which invariably incloses the lamp, quickly becomes coatedwith dust and constantly requires attention to prevent the consequent dimming and loss of effectiveness of-the lamp.

' By the utilization of my invention I pro vide a lamp which combines-a red light or danger signal in connection with the tail lamp for illuminating the number or license plate of the automobile; which is compact and simple in construction, facile in its ma.-

nipulation and accessibility, efficient, and

economical.

The invention consists in certain novel features of construction and combinations and arrangements of parts as hereinafter set forth and claimed.

In the accompanying drawings I have illustrated one complete example of the physical'embodiment of my invention con- -'structed according to the best mode I have sofar devised for the practical application of the principles of the invention.

Figure 1 is an elevation of the device complete, ready for attachment to an automobile. Fig. 2 is an end view of Fig. 1 looking from the right. Fig. 3 is a bottom plan view of Fig. 2. Fig. 4 is an enlarged, de-

tail view, partly broken away, showing the manner of supporting the lamp'as indicated in dotted lines Fig 3.

Inthe referred embodiment of my invention I ave illustrated an electriclamp as the illuminating medium in'closed within the hood or casing l. The hood is prefer ably of sheet metal, nickel plated on its exterior for ornamentation, and either enamssaled or painted white on the interior for the pin-pose of reflecting the rays of, light from Specification of Letters Patent. I Patented J 'lln e' 23, 191&." Application filed January 12,1914.

' Serial No. 811,578,

the lamp. bestsee i TQthehoodor casing is semi-circularin cross section or tom of the hood is illustrated as boundedby -the horizontal .flange to which the sci'e'en 3 of foraminous material is secured at three sides.

which projects below. tl'ie; ho.od .p1;0per throughout its entire length. A cylindrical barrel" 5, integral with the hood projects therefrom, and is providedwith a lens 6] used. This license or numberplate is sep The fou1'tl1 si cle,.0f the screen issef cured iii-the bent back wallf l 'offthe ho'od concavo-convex, and inFig. :3 .the jopenbot- 6 cured between the back wall 4 and abase plate bolts or screws 9, and this base plate isi-n'turn adapted to be attached to a part of the automobile'inthe, customary manner. y p I The lamp bulb 10 which provides theilluminationof the "device. is introduced into and retained in the hood in a novel and .especially meritorious manner. 11 of the hood is provided with an orifice of suitable size and this orifice is bounded and its walls strengthened by a cast ring 12 formed with a threaded flange 13 projecting inwardly from the hood wall 11. It will be noted that the inside diameter of the flanged ring or plate 12 is of sufficient size to permit the entrance of the lamp bulb 1 0, and this flanged ring is adaptedto receiveathreaded ferrule or hollow plug 14 having a knurled turning handle or head 15 at the outer side of the hood and a reduced stem 16 project- 7 ing inside the hood. The stem 16 is-for the attachment of a pipe 17 which'is threaded on the stem and on the electric lamp bulb 10. The wires 18 are introduced through the opening in the ferrule and stem. thence through the pipe 17 to the lamp where they are attached in customary mannen From .thisdescription it will be seen that the lamp may be removed,-bodily, from the hood, by turning the handle or head 15 to The end wall 17 is of a length suitable to bring the lamp bulb directly behind the lens or red glass 6 as seen in Fig. 1, and its central location permits an equal distribution of the light rays, direct, and by reflection from the walls of the hood upon the license number the lamp and number plate, and yet does not interfere with the rays of light shed from the lamp.

From the above description taken in connection with my drawings it' is evident that I have provided an automobile lamp which fulfils the purposes and objects set forth to be accom lished by my invention. 1 What claim is In an automobile lamp, the combination with an open bottom screened hood having a flange threaded ring attached at the inner side of one of its end walls, a threadedopen plug screwed into said ring, a'threaded stem promoting from the plug, a, threaded pipe screwed on the plug, and a lamp supported in the pipe as described 1 1 In testimony whereof I afiix my signature in presence of twdwitnesses.
