RAILROAD Application filed J'uly 23,

To all whom it may concern: a

v Be it known that I, EDWARD, D. a citizen of the United States, residing at Tucson, in the county of Pima and State of Arizona, have invented certain new anduseful Improvements in Railroad Lanterns; and

. I do hereby declare the following to be a full, clear, and exact description of'the invention, such as will enable others skilled in the art to which it appertains tomake and use the same. a V This invention relates to new and useful improvements in lanterns especially adapted for use on railroads to give signals and for various other purposes and has for its primary object the provision of a device ot the above stated character which will be evenly balanced owing to its compactness and arrangement of parts, so that the same maybe conveniently handled when giving signals or otherwise used. 3

Another object of this invention isthe provision of a novel ventilating means which will insure proper burning of the flame-and obviateany danger of. the flame being ex-v tinguished by wind or storms or from rough use to which the device may be subjected.

A further object of this invention is the provision of means which willfirmly lock the fuel bowl or receptacle toethe frame and prevent accidental detachment of the same;

during the use of the device or in case the device ispositioned on or struck by an object.

nation, and arrangement of parts as will be hereinafter claimed. 7

The eyes 5 are formed by bending theupper ends of said vertical members upon themselves and said loopmembiers orears 4: are adapted tore ceive the ends of a bail or handled The lower anunlar mem-berl is adaptedto; form a base or support for the frame and' the side members between athelower and intermediate annular members are bent inwardly.

element 8 The lower portion oftheiglobe or 1 chimney supporting element 8 is curved inwardly as illustratednt 9-and is provided? I i with an opening 10 to? receive a iu'el-bowlor receptacle 11 andwsaidop ehing'm is disposed'in'a plane above the suporting annular 1 member 3. ,Anqannular bead 12 is'formed I I on the inner face of; the globe supporting element 8 adjacent its, upper edge and-is adapted'to form a seat for a globe or chim- "neyf13,-of anywel'lknown constructionj The:

lower. end of the chimney-or. globe extends ment 8 will be unobstructed. The air is adapted to pass through the openings 1% and strike against the chimney or globe 13 and be deflected downwardly and inwardly when it passes upwardly in the chimney or bowl around the burner 15 carried by the fuel bowl or receptacle 11 andwhich is located within the chimney or globe.

The curvature 9 of the globe supporting element 8 also aids in deflecting the air under the lower edge of the chimney and upwardly therein about the burner so as to insure a proper burning of the flame on the wick of the burner and obviate a direct draft against the flame.

The fuel bowl or receptacle 11 consists of a body 16 adaptedto contain the fuel and has formed in its top wall 17 a screw threaded opening 18 to receive the burner 15 andits wick. A screen 19 is located within the body 16- and is provided with an opening 20 to permit the wick of the burner to extend downwardly in the'body. The body 16 has formed thereon an annular and down wardly depending wall'21 of a diameter greater than the diameter of the body 16 which has formed upon its lower edge an annular flange 22 adapted to engage the globe supporting element 8 about its open ing lOand against the outer face thereof. A pair of brackets 23 are secured to the outer face of the bottom of the body 16 within the supporting wall 21 and slidably supports substantially U-shaped locking elements 2 1. The arms -15 of the locking elements 24 have interposed between the same an expansion spring 26 for the purpose of urging the locking elements away from eachother. The arms 27 of the locking ele ments have formed thereon right angled latch elements 28 that extend through slots in the wall 21 and engage the globe supporting element 8 upon its inner face and above the opening 10 to cooperate with the flange 22 in securing the fuel bowl or receptacle 11 within the chimney supporting element and provides a construction which will permit the easy removal of the fuelbowl or receptacle when desiring to clean the burner or fill the body 16 with fuel. This also to be noted that the locking elements 24 are confined within the wall 21 and are prevented from coming in contact with obstacles which may have a tendency to accidentally unfasten the bowl 11 from the chimney supporting element 8. Further it is noted that the body 16 containing the fuel is supported a considerable distance away from the ground when the frame is positioned on the ground. thereby keeping the fuel. from coming in contact with the ground which has considerable advantage in extremely cold countries as fuel sometimes contains a large percentage of water or other freezing fluid and when allowed to contact with snow or ice or frozen ground the same is liable to become frozen rendering the lamp void of further use until thawed out.

A hood 29 is hinged to the upper annular member 3 of the frame 1 and is detachably secured to the frame at an oppositely disposed point by a spring catch 30 which consists of a resilient wire'31 secured to the hood upon the inner face'thereof and has an annular related catch formed on its ends which moves through a bracket 33 and ongages the annular member 3 of the frame to retain the hood in engagement with the frame but which will permit the hood to be swung laterally of the frame when desiring to remove the chimney 13.

The hood 29 is provided with a conical portion 35 which engages the upper annular member 3 of the frame 1 and a ventilating cap 36 provided with a series of openings 37 in its side wall. The cap 36 is of hollow formation and the top wall thereof has secured thereto a pair of resilient fastenin members 38 adapted to pass through a slot 39 in a ventilating cap 40 and then bent laterally to retain the plate 10 within the cap The ventilating plate 40 is located in the lower end of the cap 36 and is urged downwardly by means of an expansion spring 41 located between said plate and the top wall of the cap. The plate 40 has spaced ventilating slots 12 which permits the air passin upwardly through the chimney to escape through the cap 36 by way of the openings 3? thereof. Deflecting plates -i8 are formed on the plate -12 and are disposed in diverging planes and overlie the slots 12. Tnclined and arc'uately curved deflecting elements 44- are formed on the plate 520 adj cent the ventilating slots 42 and overlie a portion of said slots and cooperate with the diverging deflecting plates 4:3 in preventing a direct draft downwardly through the cap into the chimney or globe 18 but which will permit a free passage of air upwardly through the chimney and outwardly of the cap.

Having thus described my invention what I claim is A lantern having a burner, a globe there for, a plate provided with an inclined wall to rest on the upper end of said globe and having openings therethrough, deflecting elements secured to said wall and disposed over and partly closing said. openings a cap over said plate, an expansive spring intermediate said cap and plate, said cap being closed at its top and having draft openrections and in contact With the lower sur- 10 ings through its side Walls, deflectors inteface of said plate.
