Application filed .une 29,

To all whom it may concern:

Be it known that I, DOLPH Il. InAHM, a citizen oi' the United States of America, residing at the city oi St. Louis, in the State oi Missouri, have invented certain new and use- 'ul Improvements in Lantern-Burners, oi which the following is a i'ull, clear, and exact description, reference being had to the accompanying drawings, forming part oi this specification.

Illy invention relates to a lantern burner Vl'or use in coal-oil burning lanterns and it has for its object the production oi a burner for use in the hind of lanterns mentioned, frein which a steady ilarne can be secured and a burner that so protects the ilaine as to prevent extinguislunent thereoiFV in the swinging oil the lantern -l'or the purpose ol' Giving signals, as lor instance those eonnnoniy given. in the use ol hand carried railroad lanterns.

Figure I is atop or plan viewY oi iuy iniproved burner partly brohen away. Fig. II is aside elevation oi the burner partly in section. Fig. III is a vertical cross section taken on line III-III, Fig. I the body being shown in elevation. Fig` IV is a side elevation oi'a inodirpied iorin of burner. Fig. V is a view of the burner shown in Fig. IV partly in eleva tion and partly in vertical section taken on line IVI-II, IV. Y

In the accompanying drawings: l designates a wiely tube and 2 the body of iny burner in which the wich tube is litted. The body 2 is provided at its upper end with an outwardly flaring annular rini 3 that serves to deflect upwardly inoving air currents away i'roin the upper end ol the wiel; tube which extends above the body oi' the burner. rIhe wiel; tube has secured to its upper end an air controlling housing` through which air is delivered to the wich and 'flame burning thereironi in the use of the burner in a inanner to supply the necessary oxygen to the flame without there being any liability oi' the delivery oi` a current of air to the lanie ol' sutilcient strength to extinguish such i'laine. The air controlling housing carried by the wich tube embodies the following elements.

4 is a wing plate receiving and attached at its center to the wick tube near its upper end and provided with downwardly extending and spreading inner wings 5 containing slots or air passageways 6 and also with outer upwardly extending and converging irnperiorate wings 7 separated troni the Patented Aug. 17, 1909.

190B. Serial No. 440,879.

linner wings to provide air ducts lor the ascent of air at each side oi the wick tubo aliter it has passed through the slots or air passage-ways 6. The outer wings 7 extend upwardly to points adjacent to the top of the wich tube and they are suihciently spaced apart lroin the wiclr tube at such points to provide 'lor the access oi the ascending currents ot air to the wiel; that protrudes above the wick tube during the use of the burner. The outer wings 7 are 1)rovided at their upper ends with vertical guards 8 located at the sides oi the wick tube and projecting 'upwardly beyond the top ol" said wich tube. the necessary combustion and to prevent the passage oi strong currents of air i1nn1ediately across the top ol the wich tube and the upper end ot the will; to obviate the such currents ot air. To provide tor the ieeding oi air to the l'larne at the location oi the guards, I produce therein pertorations 9, see 7Eig. III, through which the necessary air may pass gradually to inix with the air that ascends in the air passages between the inner and outer housing wings 5 and 7 after gaining access thereto through the slots or air passageways 6 in said inner wings. At the ends ot the guards S are out-turned lips I0 that extend troni the side edges oi the wich tube and by their presence serve to strengthen a llanie burnin(r iroin a wich in the wich tube, inasniuch as when they beconie heated they causY such Haine to be drawn outwardly to the lips.

The air controlling housing of niy burner is preierably closed at its ends by end plates l1, thereby rendering it necessar f that all air supplied through the housing by upward passage therein inust enter the housing through the slots or passageways 6 at the bottoni oi" the housing. The end plates just mentioned may, however, be omitted with the result oi producing a inodiiied forni oi burner illustrated in Iligs. IV and V which correspond in other particulars to the burner I have herein previously described.

For the purpose of holding the air controlling housing oi my burner rigidly to the wick tube oi the burner and to brace the parts thereof, I apply to the wick tube a stay or brace trarne that is secured to the air controlling housing. This traine coinrIhe guards 8 serve to create r likelihood oi a ilaine being extinguished by prises a pair ot wires 13 located at the sides ol the Wiclrtube and having` eyes at their ends which receive stay Wires 14. These stay Wires and the wires 13 are connected to the Wicktuoe by solder or other suitable means and the stay Wires extend outvardly from the Wick tulee and then upwardly around the Outer Wings 7 of the air controllingl housing to which Wings they are secured by seating,l them in sockets 15 carried by the Wings. The outer and upper ends ot' the stay Wires are preterahly permanently and rigidly attached to the sockets just inentioned by applying solder to the wires and sockets.
