LAMP OR ILLUMINATOR.

Specification of Letters Patent.

Patented Sept. 19, 1911.

Application filed. April 21, 1911. Serial No. 622,456.

To all whom it may concern:

Be it known that IJVILLIAM K. Lnnrnnrr, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new Lamp or Illuminator, of which the following is a specification.

My invention consists of a lamp or illuminator which is composed of a plurality or set of burners which are arranged at varying angles to each other and disposed in front of a reflector so as to diffuse the lights of said burners directly ahead and laterally, or to the right or left, or both right and left, whereby the path in front of say a vehicle, boat or the like, will be illuminated to a greater width than that afforded simply by directly forwardly, a feature of importance particularly when a vehicle, boat, or the like equipped with the same turns aside or around corners, provision being made also for extinguishing the side burners of the set Without affecting the central or direct ahead burner.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific arrangement and organization shown and described.

Figure 1 represents a top or plan view of a lamp or illuminato-r embodying my inventipn. Fig. 2 represents a front end elevation thereof, portions of the same being broken away. Fig. 3 represents a top or plan view of another embodiment of my invention.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings :-A designates an arm which is of curved segmental form, and B. G. C. designate a series of burners which rise therefrom and are secured there to in. any suitable manner, they constituting a central burner and a burner at each side thereof.

D designates a tubular plug which forms a downward continuity of the burner B and has its bore E in communication with that of said burner, said plug being also secured to the arm A and supported on the plate F which latter is aflixcd to a suitable member Gr of a vehicle, boat, or like article by the Screws H or other means.

ing the valves through the medium of the heads or handles L, the said valves may be closed or opened so as to cut oil' or let on the illuminating gas employed for said burners, without. affecting the supply of gas to the central burner B, it being noticed that the plug I) has connected with it the nipple M with which may be connected a conduit or pipe leading from a place of supply of gas.

It will be noticed that the burners B. C. G. are disposed in front of a reflector N, shown in dotted lines and adapted to be supported on a vehicle, boat, or the like, in the present case, an automobile, it being noticed that the curvature of the arm A causes said burners to be in accord wit-h the curvature of said reflector, consequently the burner B will have its light projected directly in front and the burners C will have their lights projected respectively to the right and left as shown by the dot-ted rays Fig. 1, consequently, the

path in front of the burners will be illuminatcd to a greater width than would be afforded by a single burner or a set of burners in right lined direction with each other instead of the curvature in direction shown in harmony with that of the reflector, as has been stated, and the tips P of the side burners C C while standing at an inclination to the top of the burner B preserve right angular positions to the portions of the reflector behind the same, thus producing the best results in reflecting the lights of said burners C to the right and left.

In Fig. 3, I show the illuminators of opposite sides of the vehicle, etc, as composed each of a central burner B and a single side burner C. In this case neither of the said side burners reflect its light to the opposite side crossing the center of the vehicle or the like, but one burner of a side has its light reflected to the right, and the burner of the other side has its light reflected to the left, and so these actions in connection with the reflected light of the central burner illuminates the path in front of the vehicle, to a greater extent than will be afforded by the use of only a single burner, Which directs the light directly ahead.

Having thus described my invention What I claim as new and desire to secure by Letters Patent, is

1. In a gas-supplied illuminator, an arm, a plurality of burners supported thereon, a tubular member depending from said arm and having its bore in connection With one of said burners, said tubular member hav ing lateral branches, connections between said branches and the other burners, valves in said branches, and an attaching member on which said tubular member is supported.

2. In a gas lamp, a curved reflector, a main burner, and an auxiliary burner at one side thereof, the tips of each of said burners being set perpendicular to that portion of the reflector nearest said tips.

3. In a gas lamp, a curved reflector, a main burner, and an auxiliary burner at one side thereof, the tips of each of said burners being set perpendicular to that portion of the reflector nearest said tips, a gas supply common to said burners and at all times open to said main burner, and a valve for the auxiliary burner, whereby the light of the latter may be adjusted Without interfering With that of the main burner.
