LAMP.

Specification of Letters Patent.

Patented May 11, 1915..

. Application filed may 5, 1911. Serial No. 625,217.

To all whom it may concem:

Be it known that I, ROBERT C. SHAAL, a citizen of the United States, residing in Port Chester, county of Westchester, and State of New York, have invented new and useful .Improvements in Lamps, of which the following is a description.

My invention pertains to that class of lamps usually carried upon vehicles and has for its particular object to direct the rays of the source of illumination in desired directions.

In the drawing lfiigure lrepresents a vehicle to which my improved lamp is applied. Fig. 2 is a vertical section of one type of lamp illustrating my invention. Fig. 3 is a longitudinal section of my lamp looking downwardly upon the line A-B.

In Fig. 1, 1 represents a vehicle to which my improved lamp is applied, the same being indicated at 2 and provided with the usual glass front 3 allowing the rays of the source of illumination to be projected forwardly as is usual in vehicle side lamps. The transparent side 4 allows rays to be projected at right angles to the body of the vehicle as is also usual in ordinary side lights. The bottom portion 5 of the lamp 2 is provided with means for directing light rays downwardly and toward the rear of the vehicle'in such manner as to illuminate the running-board 6 and other objects in close proximity to the running-board as, for example,-.the stepping-stone or other objeets in the vehicle.

One of the forms'of my lamp which is preferred by me is shown; in Fig. 2 as provided with the body portion 8 carrying a spider 9 which carries the socket 10 into which is placed the bulb 16; with which electrical communication is established as by means of the conductor '12.

Any type of suitable reflector may be used for directing the rays of the bulb 16 in desired directions as indicated at 11.

13 represents a blank side of the lamp which prevents the same from shedding rays toward the center of the vehicle which would tend to confuse the driver.

14 represents the back portion of the lamp which is preferably made of metal and provided with the usual bulls-eye 15. The glass in the front of the lamp for allowing the rays. to project ahead of the vehicle is path of one alighting from the indicated at 3, while 5 represents a glass prismatic bottom portion of the lamp having its prisms so designed as to throw light backwardly and downward in what I term a cone of small divergence, as indicated by arrows in such manner as to illuminate the ground immediately in proximity to the step so that one alighting from the car may readily see where to step with safety.

In Fig. 3 like numerals are used to indicate like parts and the side 4 which is preferably made of glass isshown as provided with a hinged door, which may be locked the vehicle as, for example, that portion ofv the road .where one would step in alighting from the vehicle, which I find a very valuable feature in this ty e of lamp.

It will be obvlous that various types of illuminants may be used in connection with my lamp and that many types of reflecting and refracting and otherwise directing means may be used for directingthe rays in a desired manner and still remain Within the scope of my invention. I, therefore, do not limit myself to any details of construction or exact arrangement of parts shown and described for the purpose of illustrating one type of my invention which is as set forth in the following claims.

- I claim- 1. In combination with a vehicle, a lamp supported thereby, said lamp comprising a rectangular frame having a source of light supported therein, a-blank side toward said vehicle, and also having a light-refracting bottom so formed as to direct the rays of light rearwardly and downwardly.

2. In combination with a vehicle, a lamp supported thereon comprising a frame having asouroe of light supported therein, and a reflector in cooperative relation to the latter, said frame having a bulls eye in its ac and a light-refractive bottom comstructed so as to direct the rays of light rearwardly.

3. In combination with a vehicle, a lamp supported thereon consisting of a frame having its top and the side toward the vehicle closed, said frame having also a'transparent front, and a light-refractive bottom constructed to direct the rays of light to-- ward the rear of the vehicle.

4. A lamp for vehicles comprising a rectangular frame, having one side blank and its opposite side transparent, and having a transparent front, and a bulls-eye lens in its back, and also a prismatic bottom.

5. A lamp for vehicles comprising a rectangular frame, a source of light suspended therein, a reflector arranged in cooperative relation to said source of light 'so as to direct ROBERT C. SHA'AL.
