SIGNAL-LAMP.

Specification of Letters Patent.

Patented Aug. 26, 1919.

. Application filed June 27, 1918. Serial No. 242,150.

b all whom it may concern 1 Be it known thatI, FURMAN D. SPEAK, a citizen of the United States ol. America, residing at New York city, county and Statoof New York, have invented a new and useful Signal-Lamp, of which the following is a specification.

My invention relates to signal lamps for railroad use, particularly of the type termed classification lamps. structurally, it is essentially an improvement upon the lamp shown and described in my former Patent #816,509 of March 27th, 1906. The object of the present invention is to provide in a classification lamp novel features of construction whereby it may be readily adjusted and put in condition for giving the desired signal. Classification lamps are located on the front end of locomotives and motor trains, and are arranged to throw a light directly ahead and -a corresponding light laterally at the outer side of the train, one of said lamps being provided on each side of the locomotive or motor. lVhen the light whichis projected ahead and laterally by each lamp is white, it indicates that the train is an extra. lVhen there is no light it indicates that the train is a regular. When the light is green, it indicates that the train is in sections.

Ordinarily, different lamps are required for these different signaling purposes. By my improved construction, a single lamp may be used to indicate these three different conditions.

In the drawings:

Figure 1 is a vertical section of my improved classification lamp mounted upon a suitable bracket.

Fig. 2 is a horizontal section thereof through the center of the lens.

Fig. 3 is a perspective view of one form of the lamp support or bracket.

1 represents a bracket which may be of any suitable construction designed to support the lamp and hold it in the desired position. 2 represents the base of the lamp, which, in this particular case, is of circular outline and is designed to slip into the opening in the ring of the bracket 1 and to be held in any suitable way against rotation as by a pin 3 carried by a spring 4, the pin being projected, through the ring of the bracket and into a hole in the base of the lamp adjacent thereto when the lamp is in place. As shown in the drawings, in Fig. 1 the lamp base 2 may have two oppositely positioned holes for the reception of the pin 3 so that the lamp may be held in either one of two positions 180 apart. 5 represents a burner of any suitable type as the source of light. 6 represents the main body of the lamp. In this particular case, 7-7 represent plain white glasses or lenses which are arranged 90 apart in openings in the main body 6. 88 are green glasses or lenses which are located diametrically opposite to the two white lenses. Assuming that the lamp shown in F ig. 2 is placed on the front end of a locomotive or motor at the right hand side, the front lens and the right-hand or outside lens will show white. Obviously, to prevent confusion, the other lenses should be hooded or shielded in some manner suitable to prevent light from passing therethrough. To that end, I provide a shield comprising opaque plates or shutters 9-9 which are arranged in a vertical plane to stand between one set of lenses and the source of light. The ends of these shutters 9 9 are provided with pivot shafts 10-10 which pass out through the lamp body 6 and are provided with one or'more operating handles 11-11 which may be conveniently located outside of the lamp, whereby, by turning the handle or handles, the shields may be swung over to hood the green lenses or the white lenses at will. In the particular form shown in the drawings (Fig. 2) the shields 99 are positioned to cut off the light from the green lenses, hence, with the lamp mounted as aforesaid, the signal lamp would indicate, if lighted, that the train was an extra. If it should be desired to indicate that the train was infsections the spring held pin 3 would be withdrawn and the lamp body turned 180 so as to present the green lenses at the front and outside of the train and the shutters or shields 9-9 would then be turned over or reversed so as to cut oil' the light to the white lenses, then located at the rear and inner side. If the train is a regular, the burner could be removed or the light extinguished. Thus, by this comparatively simple arrangement I am able to provide in a single structure means for indicating any one of the three signals characteristic of classification lamps. ()bviously, the structure of the lamp must be such that it can be turned angularly in the bracket so as to position the desired lenses forthe proper signaling effect, and it is also essential that the shields shall serve to cut off the light from tWo lenses at the rear and inner side of the lamp, OthGlWlSG confusion WOLIlCl result. The shield 9 9 may be made modifications in the details of construction may be resorted to Without departing from the spirit and scope of this invention, and that I have attempted herein to describe and illustrate onlyone preferred form of said invention.

That I claim is: I

1; In a lamp, a body having two sets of oppositely arranged light openings With glasses of corresponding color in one set and glasscsof anothercolor in the other set, both glasses of one set being arranged adjacent to each other, means for. supporting the lamp for angular adjustment to present the desired set of glassesin the desired position, a source of light Within the body, with means mounted within the lamp body and movable therein for cutting off therays of light from the sourceof light to one or the other set of glasses at will. i v

2. In a lamp, a, body having two sets of oppositely arranged light openings With glz'tsses of corresponding color in one set and glasses of another color in the other set, both glasses of one set being arranged adjacent to each other, means for supporting the lamp for angular adjustment to present the desired set of glasses in the desired position, a source of light Within the body, With movable means Within the lamp-body for cutting off the rays of light from the source of light to one or the other set of glasses at Will, said means comprising a shutter pivotal'ly mounted in said lamp body.

3. In a lamp, a .body having two sets'of oppositely arranged light openings With glasses of corresponding color in oneset and glasses of another color in the other set, both glasses of'o-ne. set being arranged adjacent oppositely arranged light openings With glasses of corresponding color'in one set and glasses of another color in the other set, both glasses of one set being arranged adjacent to each other, means for supporting the lamp for angular adjustment to present the desired set of glasses in the desiredposition, a source of light Within the body, With movable means Within the lamp body for cutting oil the rays of light from the source of light to one or the other set of glasses at will, said means comprising a shutter pivotally'm'ounted in said lamp body in a substantially horizontal plane, and means external of the lamp body for operating said shutter. i Y V 5."In a lamp, a body having tWo sets-of oppositely arranged light openings With glasses of corresponding color in one set and glasses of another color in the other set,-both glasses of one set being arranged adjacent to each other, means for supporting the lamp for angular adjustmentto present the desired-set of glasses'inthe desired position, a source of light Within the body, With movable means Within the-lamp body for cutting off the rays of light from the source of light to one or the other set of glasses at will, said means comprising a-shutter pivotally mounted in said lamp body in a substantially horizontal plane, and means external of the lamp body for opera-ting said shutter comprising a handle connected to one end of the pivotal portion of said shutter 7 F URMAN D.
