i i sHAnowLnss LANTERN.

M To all whpm it may concern:

vBe it known that I Gnomes A. Misti-N, a slib'ectof the Emperor of Austria, residing at ilwaukie, in the county of (llackamas and State. of Ore on, have invented certain new and useful mprovements in Shadowless Lanterns; and I do declare the follr'min to be a full, clear, and exact description reon'st 'ing. of an oil tank,

the invention, skilled in the art to which it appertains to make and use the same, i i

i This invention relates generally to illuminating devices and more particularly to certain'new' and. useful improvements in retofore, most hand lanterns have been rotated with a supporting base c'onsisb ,u'sually large and prevents the rays of light.

from radiating downwardly. It is to over- .come this difliculty that the present invcn- 3 :tion. isldevised, and to this end it consists of a. supporting base which is made of co m- 1 paratively thin! and light material which "preciable amount.

' further object of the invention is to 1 generally ixnprove upon devices ofthis class y the provision of a comparatively simple, I and Inexpensive construe tion, one which will be efficient and reliable in operation, and well adapted to the purpose for which it is designed.

With these and numerou's other objects 'inview, the. invention consists of certain hotel features of construction, and the combination'and arrangement of parts as will be hereinafter fully described and cleimed.

indicated bythe line 4-4 of .Fig. '1; and,

Fig. 5 a detail sectional view taken: on the plane indicated Fig. l. k e A o Referring more particularly to the drawings. the muncral 1 designates wfuei tank, which is of cylindrical construction, having :1 convex'o, concave top 2 secured thereon in any suitable manner and provided with a filling opening 3 hovin a, cap 4 fitted therein. The cap 4 is provi ed with an inwardly opening spring pressed valve 5 in order that air may be pum ed into the tank should it. be found that" tie force of gravity is not suflicicnt. to cause the 'fuel to run to the burner) Thebottoinol the tenk 1 is pro-- vided with n downwardly projecting eccen tricaliy :u'raned nip 'ilefi, the purpose of which will be iereinafter described.

The nipple extends through suitable openings arranged in an asbestos plate 7 and a metallic crown plate 8. the latter forming the top of a cylindricalcasing 9. As shown, the upper end 'of the casin Sis provided with a horizontally dispose outwardly-extending annular flange 10, and has its u per side contacting with the lower side of the by the line 5-5 of plate 8 and is secured thereto by means of V )OltS 11, whichhave an additional function to be hereinafter described. The Walls of i the casing 9 are perforated as at 12 to provide proper ventilation in the same, as will be obvious.

Threaded to the nipple 6 is the upper end of a short tube section 13, the lower end of which is likewise secured to a small casing 14 having a needie valve 15 mounted therein. The stem of this-Valve extends through one of the erforaticrlltin thewgll of the casing tel pipe section 17 contains a, wick AU-of suitable material, and threadhemp or other end of this pipe section is a ed in the free nozzle 21. p

The mixing chamber 19 constitutes the IQQ vertically disaosed portion of a casing having inverted -shaped portions 22 communieating with said vertically disposed portion by means of a narrow neck 23. This casing is arran ed beneath the crown. plate 8 centrally o the same, and secured t ereto by a bolt 24 which extends through the crown plate and through a lug formed on the top of said casing. Formed at the to of the i0 casing on the interior of the same a ove the neck 23 and between the inverted U-shaped ortions 22, is a rib 25, the purpose of which 18 to divide the gases as they pass from the mixingchamber 19 through the neck 23 and cause them to flow around the U-shaped portions 22 into tubes 26 which are threaded at their upper ends to said U-shaped portions and which are provided at their lower ends with suitable burnersin the form of incandescent mantles 27. As shown, these mantles 27 are disposed a suitabledistance below the plane of the lower end of the casing 9.

The mixing chamber 19 is provided with an internally threaded opening in one side thereof in which is fitted the inner end of an air pipe 28. This air pipe 28 inclines downwardly from its point of connection with the mixin chamber and has its outer end exten'de through the wall of the casing 9 near the lower'end of the same and curved downwardly. By this construction air from the outside atmosphere may .be conveyed into the mixing chamber without any dange of rain or dust gaining entrance to the same.

as The numerals 29 represent inwardl extending stops which are secured to the inner wall of the; casing 9 near the lower end of the same. Resting against these stops 29 is the annular flange 30 formed at the upper endof an inverted transparent globe 31, the

lower end of which is provided with air inlet openings This flange 30 extends outwardly of the globe and is of a diameter substantially equal to theinternal diameter of the casing 9, to cause a rather snug fitting in the lowenend of the same.

Secured to one side of the casing 9 is a lug 33 having an eye at its lower end which forms a hinged portion for a U-shaped resilient 60 clamping member 34. This member34 surrounds the major portion of the globe 31 directly beneath the flange 30 and holds it in hinged relation with respect to the cas-' ing 9. Secured to the other side of the easing 9 is a resilient hook 35, the hooked portion of which is adapted to en age the lower side of the flange 30 of the g obe 31. This construction provides a meansi'or connecting the globe to the casing 9, and yet permits the former do be swung out of the way when lighting tlre lantern.

The supporting base for the lantern coin prises an nnular base member 36 which is arranged horizontally below the lowermost l5 portion of the globe 31. Secured at their causes a partial vaporization o the fuel be:

lower ends by rivets .or otherwise to this annular base member 36 is a plurality of substantially upright standards 37 These standards 37 consist of fiat strips and have their upper ends bent ir lteegrally as at 38 over the heretofore mentio flange 10 and ground late 8, and are secured to these parts by the olts 11. The stri are then struck upwardly and have t eir extreme ends offset outwardly to form ears 39 to 'which are pivoted the lower ends of a bail-shaped handle 40.

The intermediate portions of the strips or standards 37 are twisted into planes .disposed at right-angles to their ends so that 80 they extend edge to edge in radial directions in order not to form an obstruction to the rays of light from the burners.

nusing the device, suitable h drocarbon fuel 18 placed in the tank 1 and om this it passes through the ipe section 13 into the valve chamber 14. he valve 15 controls the sup ly of fuel into the pi e section 17. The wic 20 disposed within t is'pi 0 section 17 D0 fore it reaches the nozzle 21,'a coin lete v'aporization taking place as it issues in the latter in the form of a spray and mixes with the air conveyed into the mixing chamber through the pipe 28. The mixed gases then pass upward y through the neck 23 and di vide, some ofi them assing downwardly throu b one o the tubes 26, while the remain er passes downwardly throu h the other tube 26. The heat from the urners 27 causes a quick .va orization of the fuel. In first light n the antern it is necessary to heat the various arts with a match before applying it to t e burners. The ashes, tos plate 7 prevents the fuel tank 1 from becoming hfiated from the heat from the burners 27 and cons uently eliminates the danger of x losion i i the fuel.

From th: oregoing description, taken in connection with the accompanying drawings, it will be seen that the objects of the invention have been eflectively carried out as-the supporting base of the lantern is 0 such skeleton structure that it will not obstruct, an appreciable amount of thcrays of light from the burners.

As various changes in form, proportion, and in the minor details of construction may 'be resorted to without departing from the spirit of this invention, it is to be understood that I do not wish to be limited to the precise construction herein shown and described.

I claim:
