LAMP.

Speeicetion o1' Letters Patent.

Patented July 23, 1918.

Application led October 11, 1917. Serial No. 195,913.

To all 'whom t may concern:

Be it known that I, Meren N. FlNKELsTEIN, a citizen of the United States, residing at i Greenwich, Connecticut, have invented eertain new and useful` Improvements in Lamps. ot' which the following is a clear, full, and exact description.

This invention relatos to improvements in la1nps,such as head-lights for automobiles or the like, of the type in which the direct rays o" light from the lamp are shielded at the upper portion ot' the from, of the lamp so that the useful rays ot light for the one driving the ear are. directed upon the ground in front of the lamp, One of thc ob]eets of the present invention is to provide means for illuminating, lo a certain extent at least, the front surface o l the light shield so that the front of said shield will not appear so darkly contrasted with the space throuGh which the direct rays of light from tie soul-re of light are east. Further objects of the invention are to provide a practical etticient and durable lanip oi' the type mein tioued.

These lining among the objects of the present invention,` the same consists of certain features of construction and mlmhinations of parts to he hercimrlter described and than rlaimed with reference to the arronlpany ing drawings illustrating an embodiment of the invention. in which- Figure 1 is a Jfront elevation of the improved lamp without the lens;

Fig. 2 is a central vertical section of the lamp; and

Fig. 3 is a horizontal section on th'e line 3-3 Fig. l.

Referring to the drawings, the lamp Acas4 ing l0 contains a main retlectoi.' 1l, in which is hal-ai ed the source of light, lhere shown as an inramlesrcnt electric lamp l2, which is suitahlv mounted in the lamp in any weltlmown manner. Mounted upon the lamp is the lens 13, and preferably the improvements corr stitnting the, present inwntion are arranged within the lamp back of said lens.

Light inten-,opting means is provided lu' a senricirrular shield il of sheet metal. the curved edge ot which is provided with iutegral lugs l5 passed through slits in the month of the riivftor ll and turned over and soldered to the back of said reector, so that said shield covers approximately onehalt' of the said mout-h, whileits loaver'edge 16 will be located at the approximate diameter ofthe lamp.

Supported by the lower edge-of the shield 1l is a narrow horizontal metallic strip 17, which extends substantially parallel with the lower edge of the Shield, and is provided with bent-up 'bracket portions 18 at the ends, which are soldered or otherwise suitably secured to the back of the shield, the reflector being thereby located in front of the lower portion of said shield. Preferably the shield 1l is inclined slightly rearwardly while the strip 17 is inclined from its lower edge away from said shield so as to be positioned at an acute angle thereto. The adjacent surfaces 19 and 20 of the shield and strip 17 are so made as to constitute reflecting surfaces, with the result that the rays of light from a source ot light positioned properly to the rear ot the said surfaces will be reflected from the surface Q0 backwardly upon the refecting surface l5) from whence the rays are again reflected in a forward direction. This will result in illuminating the front surface lJ of the shield to such' extent that it will not. he dark as would ordinarily be thc ease, but will have a. light value more in harmony with the direct rays of light which are rast below the shield forwardly from the lamp.

Ii an incandescent electric lamp such as l2 is employed to provide the illumination, a recess 2l is formed in the lower portion of the shield 14 so as to receive the lamp Vl2. Shielding nnans are also provided upon the rellecting strip IT, which means are located directly in front of the incandescent electric lamp 1L). so that no direct forward rays of light from the lamp will he cast in front of the lamp proper. To this end, the stril') 17 is provided at about its middength with a shield whirh is formed integrally therewith and vomprises an upwardly extendin f porA tion 22 provided with an inner rel ecling surface and a. dnwl'iwardly extending porlion :2li whix'h is slottedvertically at 2l. The slot 2-1 provides a gap for receiving the projecting apex of the electric lamp, which acts as an addilional support for the adjacent portions of the reflecting stilip, Urel'ornbly,y the lower projecting portion or lip titl is formed, as shown in Figli t, for enabling the one Who applies the incandescent lamp o the lamp proper to do so more conveniently, and the edges of the portion 23 are preferably stilfened by bending them bmah as shown at 25.

lt is obvious that the invention is susceptible of modification` as parts may be omitted, added and substituted without departing from the.scope of the invention as claimed.
