This invention relates to lamps or torches; and more particularly.to' improvementsfin torches ofthe sort that are employed,.for in-' stance, for lights. and as danger signals on: construction jobs and forotherout-of-door uses where; they are'expo'sed to the varying out door weather conditions, but'which are not provided with chimneysiglobesor'the like means commonly-employed in lamps: and lanterns for protecting the flame.

One object of theinvention is to. provide ao torch of this sort which willbe elfi'cient,nre-- liable and economical inoperation;

Other objects of the inventioniaretopro duce'a torch which will give the maximum light with the minimum. consumption offuel under the various different outdoor weather conditions; which is providedwith 'a' burner whlch will remain cool in operation; tLDdWlll insurea proper mixtureotaii-and gaseous fuel with a consequent improvement incombustion, a white-flame, and econorny inoperation; which will give a substantiallyrunobstructed or open flame during normal weather conditions, butnevertheless is adapted to'preventthe flame from being extingui shed bystrong winds, rain or snow {which 1s adapted to afford anexposed andlsubstam tially unobstructedflame under normal conditions, butris provided with a shield which can be readily adj usted when" necessary to protect the flame fromarainy which 'is providedwith a'movable rain: shield which can be readily positioned over the burner when desired to protect the flame fromrain and movedaway from its operativ e 'posi tioni-to, leave the fiamefexposed and zunoboperative -position over the burnep a 7 Another object-of the inve'ntionjis to prove torches; of the type mentioned, whereby.

The wick tube may besecured in the holes in the shell bottom 16 and disk 17 by expanding the ends of the wick tube at the outer sides of the bottom 16 and top disk 17 orotherwise, and the disk 17 is shown as provided with adown-turned peripheral flange '18 which'fits tightly in theshell 13 against an internal shoulder 19 in the shell,

which prevents displacement of the disk in the shell. The'bu'rner may be secured in the torch body in any suitable manner, as for instance, by screw-threading the lowernend portion of the burner shell, whereby the burner is adapted to-be screwed into a threaded opening 20 in the top of the torch body.

the lower end ofwhich provides ashoulder adapted to abut against the top face of the:

to'rchbody'to form a practically tight closure forthe burner opening 20 in the top of the body, which opening also serves as the opening forthe torch.

- The outer endof the wicktube 14 preter t-V ably extends somewhat above the top face of the vtopflwall 17 of the burner and the shell or body 13 of the burner'extends above the burner top 17 and above the outerend'of the wick. which, in its normal position, protrudes slightly out 01"? the upper end of the wick tube. The shell 13 thusrforins an opentopped tubular guard which surrounds the upper end of the wick andcwick tube and forms an open-ended combustion chamherin which the flame is protected from being ex-.

tinguished or blown out by strong winds, while nevertheless the upper end of this col-nbustion chamber is open and unobstructed so that the flame burning in this chamber can i extend out through the open top thereof illumination. (5

' represents a rain shield 'which is mounted onthe torch so that it is adapted to be supported in a position above or over the burn r and spaced from the open, upper end of the burner shellljd, or to be moved to one side or away from this position over'the burner. Preterably this rain shield is carnee by a combined shield support and carrying handle; 24 for the-torch. As shown, the support or handle 24 is in the form of a U-shaped bail, theinner endsof the two'legs of which are bent inwardly at 25 and 26 and entendloosely through radial holes in the burner body-thus pivotally connecting the bail24 tothe burner; -One of the pivots, 26, ofthe bail is preferably-long enough-to project'through a hole'intheside of the wick tube and engage or penetrate somewhat the side of the ,wick and thus serves asa wick retainer for holding the wick in adjusted positions in the wick tube and preventing the accidental displacement of the wick from the burner.

' The rain sliield"- 23.;in the construction shown in; Figs. 1-5 consists of acircular diskwhioh extends horizontally-between the 3- 7 legs of the hail 24, is vprt-"rierably of slightly dome shape having a central opening 27 ,and ismorintedon the bail by; means of a slide orcross piece 28 on which-the'disk is'rigidly' secured by welding or otherwise, and which is provided at its. ends withloops or guides 29 slidably engaging thelegs'of the bail 24;

so thatthe cross piece with the rain shield can slide freely. upand down on the bail. The cross piece 28 may be madeof a piece of sheet metal which is suitably shaped by stamp'mg or otherwise, to provide the guides or-loops-29 at its ends, and preferably the central portion of the cross piece 28 is dis-' posed beneath the central opening 27 of the .rain shield disk and spaced downwardly away-from the-central portion'of the disk.

cThus the cross piece 28 forms abaflie below thesopening 27 of the rain shield, which prefrom falling on; the wickand extinguishing the flame,- whi lenevertheless the battle 28 does notlclose the opening 27 in the rain shield, toplface' of the burneri'top, and above the but permits "the fl ame from the wick to issue and burn through the opening '27and be seen above the-rain shield. f p Preferably the ;legs' of the bail vided with lugs or projections 30 :on which the rain shield uides" 29 are adapted to rest,

. whereby when-t e ba-il 24 is in its upright po- '53:

theupper end of thefshell so that theira-in shield can, be readily n'ioved into and out of its shielding position simply by swinging the bail and without the necessityofshifting the shield on the bail to clear the burner shell.

\Yhenitis not raining and the rain shield is not needed, thebaillis-swung=down to one s de out of its vertical position, and the rain shield is adaptedto slide outwardly on thebail to a position at one side of thetorch, as shown in F 1g. 2. v shield, it is simply necessary to swing the bail to its upright position and the rain shield can slide downwardly thereon until it rests on the lugs'or stops 30, and is thereby supported above the burner. V i a v v M The bail or rain shield support 24 can be re-i i leasably retained in its upright position by any suitable means, such as notchesa3li (Figs. Band 5) in the opposite sides'of the outturned top flange 82 of the burner shell 13,

into which'notchesthe legs'of the bailfare adapted to spring or snap when the bail; is in the upright position. The bail is preferably made of spring wire with anormal tendency for the legs to springinward-ly into holding engagement with the notches.

In the construction"llustrated in' 'Figsfq' and 8, the rain shield is mountedon the burner in the manner described, but instead of the disk which forms the rain shield having the" central opening, the shield is formedbya' disk 23aha'ving a pluralityof-circumferential slits and hayingthe portions 33 of the disk opposite the slits pressed upwardlj 'sothat the slits forma plurality of'flame openings 3-4: in the disk disposed-preferably equidis l: tant about the center of the disk; As in the case of the rain shieldjfirstdescribed, the cross piece 28 is preferably spaced downwardly from the underside of the. disk so that it will permit the flame to issue and burn"throughthe openings 34 m the rain shield andw1lla'et as a battle to prevent rain which may enter through these openings from "falling on the wick and extinguishing the flame. l 3 q I T he burner; s shownasproinded at one side thereof with a lug or'cam 35"W hiCl1'is Sof disposed that if the bail is swung down front its Jupright position towards the cam 35;;the leg of the bail having th'e' long pivot engage the cam 35 which will force the lower end ofthis leg outwardly and withdraw the pivot 26 from engagement with "the wield;
