- Y This invention lrelates to lamp gaugesand `an object? ofthe invention is to 'provide for Yvisible indication to the user of the supply ofoil 'in the `reservoir of the lamp,

`i El Another feature 'of the invention isto pro :vide a floatinteriorly` of the fuel reservoir that utilizes the airchamber of thelamp for slidably guiding the float in same plane.l

-Qther, objects of the invention are to pro-` vide,in"a manner-as hereinafter set forth,

a device of the character referred to, which isstrong, compact and durable, very simple in its method of assembling, very reliable inl its operation, and comparatively inexpensive;

to manufacture and install.

` lVith the foregoing and other objects'in view, the invention consists of a novel construction, combination and arrangement of parts as will be hereinafter more specifically -zoidescribed and illustrated in the accompanying drawing, wherein it discloses an embodi? ment ofthe inventlon, but 1t 1s to be understood that changes, variations and modifications may be resorted to without departingV from the spirit hereunto appended.

In the vdrawings'wherein like reference characters denote y corresponding parts throughout the several views I Figure 1 1s a side elevation of the fuel reser- Voir of a lamp, having a portion of the reservoir walls broken away illustrating an adaptation therewith of the device in accordance with the present invention. p

Figure 2 is a perspective view of the clo- Y sure cap. Y

` Figure 3 is a perspective view of the sleeve cap. Y

Figure 4 is a perspective view of the indicator drum and operating rod. 4 A Figure 5 is a perspective view ofthe float. Referring to the drawings in details, 6 indicates the reservoir of a lamp for containing the fuel supply 'of the lamp. TheV reservoir 6 rests upon a suitable base 7 and has extend- 1 ing through the interior of. the reservoir 6 and out of the top thereof an air compartment or tube 8.v It is to be'understood that the tube extends above the base 7 and sup-V plies the burner, not shown in the drawings, with air or proper combustion of the fuel rounding the tube 8 in any conventional-manl t l.

. tight tit to prevent on the wik .of the lamp; Any eenv'eiaionai type ofvburner is .used and is adapted-to be supported on the ltopof theV reservoir surner; f The reservoir 6'isprovided-withaclo# .sure plugf9 through .which 'the fuel supplyis replenishedin the reservoir, Y y. l The reservoir v6, has ,formed integraltherewith, at the marginal portions -of1the..upper j Y face r an upstanding `necklO-thepassagefl) through-which is disposed vertically. .The

neckiscircularin crosssection',: A'v Vhollow f cylindi-icalshapedv cap indicated general-ly `at i 11- is `open, at its bottom, l The side walls ,112 of tlieca 11 are tubular in kconfiguration and longitudinal thereof. an inverted `V-shaped Y, fslot 13 V'which extends the major portionof the-length ofthe sidewalls. Y A solid top wall 14 is formedintegral with the upper edges of thefside -wa-lls and terminates in a vlaterallyv projecting fiangel. The* side wall ofthe cap 1.1 is forinedwithv a pair of openings 16, in alignmentl with each other and disposed n on th-e diametricallyfopposite sides. The top 7.5 wallfl; is-provided with anope'ning 17,-preferablyV yof diamond shaped configuration.

- The cap y11 is adapted to be inserted inthe neckV 10 .havingY the side wall 12 frictionally -abuttingthe --innerside walls of theneck 10 .and the annular flange .12 overlapping uand abutting againsty theupper edge of the,L neck wherebylthe capis inounted'in .the reser-ry voir of ythe lamp.:

. ,l lAn annular closurekv cap `18 formed with 85 anannular shoulder 19 on the innerface there- Y of adjacent thef bottom to receive. the't upper portion of the neck lOandabut againsttthe flanged lportion 15 of the capill. A transparent disc-'20 is anchored in, annular grooves 21 formed adjacent the upper edge of the vclosure cap -18 so'that/afperson canlookint'ofthev i opening landat the Sametime to provide a evaporation of the fuel in thel reservoir; 1

v A crescentshaped'float ofsuitable thickness 22 has a concaved portion-23 disposed in overy hanging relation to the air'chamber 8`so that v the float' will be guided thereby Ain thefsame place. It isto be understood that the iioat lion,

there isformediintheseside walls,extending f 22 is slidable with respect to the chamber 8. The float 22 is adapted to rest on the fuel in the reservoir in a flat relation. On the upper face of the float 22 there is formed an upstanding bracket 24 having an opening 25 therein.

A drum 26 has a pair of oppositely projecting tru'nnions y27 'secured to the opposite ends thereof along the -axis of the drum. The peripheral face of the drum is markedwith indicatingmeans such las letters,*or the like that will register with the opening 17 in .the` cap 11. rlhe oppositely disposed trurniioli's4 27 are journaled in theopenings 1-6. A rod.28 rigidly secured at one end in the peripheral Aface of the drum 26 extends through the slot 13 and on the-other end thereof is formed with a loop 29 that is movably engaged in the opening 25 on thevbrack-et24. By having the loopV A50 29 movable in the opening 25 any thrust on the .rod 2,8 is compensated for so as not to bind the trunnions 27 in the opening 16.

In the application of the invention, as the oil is consumed from-the reservoir, the oat 22 3l holds downwardly being guided in its movement by the tube 8 which is slidably encircled by the cavity: 23 on the ioat. 'When the float moves., therod 28 rotates thebarrel 26 on its Y i Y i trunnlons 27 thereby brin-ging the properly calibratedindicia in vregistration with the opening 17l thatmay be viewed on the face of the tifansparentdisc '20.,` 'It will be seen 'from the foregoing that the person is apprised of the amount of fuel in the'reservoir without requiring access to the interior thereof.

It is to be understoodthat yby describing in detail herein any particular form, structure or arrangemenuit isnot intended to limit the inventionV beyondthe terms lof the severalV claims, or the requirements lof the prior art.

- Having described my invention, what I claim as new'is l1. In 'combination with a lamp fuel reservoir, having a vertically extendingy air compartment, said fuel reservoirhaving an open voir, having a vertically extending air compartment, said fuel reservoir having an open neck therein, a cap extending into the neck and having an opening in its upper wall and a pair of aligned openings in its side wall, said capfurther having a slot in its side wall between the openings, a closure cap having diaphanous panel across itsupper face supported at the upperend of the neck over the first mentioned cap, a floatdisposed in the reservoirfin'slidable abutment with the air compartment, a drum having oppositely extending 'trunnions journaled in said pair of openings ,with its axisin parallelism with the top of th'ezca'p'so as to register indicia on the pe- 8o ripheral face thereof with theyoke in the cap, al rod rigidly securedat one end to the periphery of the drum and. at its otheren'dlmovably coupled with the float for transmitting movement of the float to the drum, saidfloat being ver) crescent vshaped and having the concaved p01:- tion thereof slidably surrounding thelair compartment. In testimony whereof k'I 'aflix my signature.
