' ILLUMINATTNG AND SIGNALLAMP.

Application filed December This invention relates to an illuminating and signal lamp which is especially used by track walkers, car inspectors and by workmen in subways, on railroads and in tunnels.

Heretofore track walkers and workmen engaged along railroad tracks have been greatly handicapped by the type of kerosene lamp in use, which failed to provide suflicientillumination and without any substantial warning signal to make their presence on the track known to an operator of an approaching train. Another disadvantage arising out of the use of the old type of kerosene lamp was its extinguishment by the suction created by apassing train which left the workmen, particularly when engagedin subways and railroad tunnels without means to illuminate their way and without any means to give warning of theirpresence on the track. Such difficulties, as far as" I am aware, have never been overcome and this invention, for the first time, provides a satisfactory means of constantly illuminating the path of the workmen, in-

suring constant illumination and providing a suflicient and reliable warning of ,their presence in the path of an approaching train. 1

Other advantages of its construction will appear from the specification and drawings. The figures of the drawings represent respectively: V V j Fig.. 1 a front elevation of this invention; Fig- 2 a side elevation Fig. 3a vertical sec: tion through the center of Fig. 2;] Fig. 4; a

lamp.

The water reservoir 1 is filled with water by removing the cap 2 and the water flows through the aperture '3, in the water tube 4:, into the carbide chamber 5. The gas generated by the action of the water on the ter mass 6 and then is burned at the burner 7. The filter mass is retained in place against the underside of the water reservoir 1 by the plate 8, which is held against the spring 9"against thenipple 10. It is to be noted that the plate 8 is of less diameter than the-diameter of the filter mass 6,sothat 5, i924.- Serial No. 754,055

which parts are causedto be engaged by rotating the bolt by. means of the wings 12.

The burner 7 projects through an opening in the burner housing .13 and the burner The spacing of the burner housing 13 from the water rcservoirl, provides. a ventilating space .2tbetween the housing and the water reservoir as is particularly observable. in F igs. and 5. The walls of the burner housing provide a. reflector whereby-the illuminating rays from the burner 7 are projected forwardly of the lamp. The front end of the burnerjhousing is provided with a lens loandsuitable ventilating openings 17 provided-at-therear ofthe lens 16.

A fdanger signal 18'is providedlatthe rear side of; the water reservoir and in line with the burning flame, sof that the presence of theuseriof the lamp will he signaled to the engineer or motorman controlling the train andw-hich danger signal consists of a suitably mounted lens of. ruby .or red color.

Light-from the bumer Z is transmitted to the danger signal 18 through the light channel,

which is formed by the tubing 19 passing through the water' reservoir. 1.; and secured by soldering at the places where it passes through the forward and rear walls of the water reservoir 1. Astrengthening plate 20 is riveted to the flat side 15 .of the water reservoir and around the light tube 19.

A suitable handle 21 is secured to thev arms 22, fastened on the water reservoir 1 by means of the screws23. A grip of the handle-21 is' lengthwise of the lampand substantially parallel to the light 1 channel so that, as the user carriesit, 'th'eilluminating stream of light will be directed forwardlyv and the danger signal will-be directedrearwardly. 1

. No particularfimportance is placed upon the" shape of the light channel, inasmuch as it may be altered'at will andgmay, if desired,

be shaped likethe burner housing 13 sothat its sides will be flaring, but it is important that the danger signal 18 bein line with the flame so that it is lllumina't'ed.

It is tobe understood that a lamp of this character zproducesgreat candle power and isnot readil extinguished. Iiifact itbnrns with as muc 1f not greater, efficiency when afburner, a reflector surrounding the burner,
