10 Claims.

s to devices for burning tes more particularly to what are ordinarily called torches, such as those used on highways, buildings, excavations and other places, for va Generally stated, the

rious purposes.

object of the invention is to provide a novel and improved construction and arrangement whereby a torch of this kind is provided, which is practical and economical to manufacture, and which in use is better protected against rain and against blowing out of constructed in a wind, in order to insure the name, and which is manner to insure better com bustion, thereby7 to increase the effectiveness and visibility of the flame, weather.

lt is also an object t under all conditions of o provide certain details and features of construction and combinations tending to increase th the desirability character.

invention consists in e general eniciency and of a torch of this particular useful ends, the matters hereinafter set forth and claimed and shown in the accompanying drawing,

in whiching. l is a plan view of a torch embodying the principles of the invention.

As thus illustrated, the hollow body i, preferably invention comprises a of metal, provided at an annular depending portion 2, provided its lower end with an inturned horizontal for a packing ring l of said body for a purpose hereinaft The removable E, forme-n an enlarged bottom por which latter rests upon vicusly mentioned. This hold the el, which material. The shell i of uprights providing their lower ends 'united which latter rests on. the

An annular outer ring, having a mentioned.

straight vertical portion resting thereon. is also provided with spring clips 5 flange forming a seat The top er explained.

burner comprises the wick tube with an external shoulder l, and with tion the lower edge olf the packing ring 5i, pre:-

tube ii is adapted to is made ol any suitable il is composed of a plurality spaces between them, with by the base portion il, shoulder l", previously l2, and a lower outwardly ilared portion i3, the latter forming a beveled flange, is secure d to the shell l@ in position to protect the name against wind, and to l admit air below it through the spaces between the lower ends of the uprights of'which the shell ill is composed. The upper ring is composed of a straight upper portion lll, having an upper inturned flange l5, provided with openings it to receive the reduced upper end portions l1 of said uprights, forming a top opening i8 for the naine, andthis ring also has a bottom ilange i9 that is downwardly flared, thereby to admit air between the lower edge of this flange and the upper edge of the portion it to the llame, and providing enough space between` the two ange rings to permit lighting of the wick. The top plate 2t is preferably a metal disk provided with openings 2l to receive the upper end portions 22 of the shell ES, which upper end porn tions may be bent down to fasten the plate in place. This plate 2li forms a cap or top piece for the burner and is provided with tongues 23, struck up from the middle of the plate, as shown, thus forming openings 2li in the top wall of the cap, with the plate E@ spaced a distance abo-ve the upper edge of the upper iiange ring lil, previously mentioned.

The burner thus constructed is preferably provided with radial arms 25 for engagement with the under sides of the spring clips 5, previously mentioned, thereby to tightly hold the burner in place within 2, previously mentioned, and upon the packing ring 4, previously mentioned, thus forming a tight joint which will prevent leakage of the fuel, whereby the latter can only escape by capillary attraction, as well as by internal pressure, through the Wick to the llame.

With the burner thus constructed, there will always be an air space above the liquid fuel, inasmuch as the level of the latter will be approximately in the pocketing of the air in the top of the hollow body tends to prevent overheating or" the fuel and prevents the latter from escaping and iiowing over the top of the hollow body, where it would ignite and might forni a serious iire hazard. The beveled flange rings l2 and l@ have a tendency to divert all winds and rain from the interior of the burner, as also do the tongue openings in the cap at the top of the burner. At the same time, these tongue openings tend to cause the burning gases to converge upwardly, with air, to provide an effective light. In other words, the construction not only more effectively protects the flame against wind and rain, but also tends to insure better combustion of the the socket formed by the portion y plane of the flange 3, and this fuel, thereby providing a practically non-blowout flame of better visibility. And, as shown and described, the burner is tightly held in a depression in the top of the hollow body which containsthe fuel, preventing leakage of the latter, while at the same time making it easy to remove and insert the burner.

The ring. Il., with its integral upstanding portions I0, is an important feature of the invention, it will be seen, inasmuch as with this feature the construction is not only strong and effective in use, but is also comparatively simple. and characterized by a comparatively low cost of production, as practically only sheet metal i's used, and. the stamping and forming operations are simple and comparatively inexpensive.

The construction thus provided results, it will be seen, in the provision of a cage-like housing for protecting the iiame against rain and wind, the entire housing being supported by means having atight fit on the. Wicki tube. This construction is comparativelyI inexpensive, but at the same time very effective in use.

What We' claim as our inventiony is:r

l.V En: a torch, a hollow body forV the fuel, having a countersink or recess in the top thereof, a wick tube expanded at its: lower end to rest in said recess, a ring encircling the reduced upper end portion ofthe wick tube, with a shoulder formed on the tubeto support the ring, integral upright portions on the outer edge of said ring, a top plate fastened to the upper ends of' said upright portions', the latter being spaced apartr to provide ai'r inlets between them,v andi a plurality of rings encircling saidt upright portions, spaced one above the other, and provided withI outwardly flared lower edge portions, forming an* apertured enclosure for the flame to protect the; latter against Wind and rain.

2. A structure as specified in claim 1, said top plate beingapertured and formed of integralmclined portions overhanging the apertures.

3. A structure as specified in claim 1, the ring immediately below said top plate having its upper edge flanged inwardly, with notches in. theflange to embrace. the upper end portions of said upright portions.

4. A structure as specified iny claim 1, said recess having an inwardly extending. bottom flange.

and said Wick tube having its lower end supported on said flange, together with means for tightly holding the wick tube in place on the seat formed by said flange.

5. In a torch, a hollow body for the fuel, with an opening in the top thereof, a wick tube removably connected to said opening, a ring encircling and fastened on said tube, said ring having a plurality of integrally formed, upright portions spaced apart at the annular outer edge thereof, forming air inlet openings between said upright portions, a plurality of annular members encircling and fastened to said upright portions, one above the other, with space between them, providing a pluralityy ofV upwardly converging beveled flanges overhanging said openings, so that air may enter upwardly under each beveled flange, with means forming an apertured covering` above the top of the interior of the cage-like housing thus formed around the upper end of the wick, to protect the fla-me against rain and wind.

Y 6. A structure as specified in claim 5, in which each beveled flange is integralv at its upper edge with a cylindrical ring-like portion fastened to said upright portions, withA the inner surface of sai'dring-like portion exposed between said upright portions.

'7'. A structure as specified inclalm 5, the lower and outer edge of one beveled flange being substantially in the plane of saidr ring onl the wick tube: and below the plane of the upper end. oisaid tube.

8. A structure asv specified in. claim 5, said ring- I on the wick tube having its inner edge turned up to provide a cylindrical upstanding portion that tightly embraces the wick tube.

9.. A, structure as specied inY claim 5, said wick tube being expanded at'` its lower end andsaidj' ring having a tight iit on the tube immediately above said expanded base portion thereof, with: a shoulder on the tube above the base to support said ring.,

10. A. structure. as specified in claim 5, the upper ends of said upright portions having direct seating engagement with said apertured covering.
